Book Review : Brilliant Blunders: From Darwin to Einstein - Colossal Mistakes by Great Scientists That Changed Our Understanding of Life and the Universe by Mario Livio

Brilliant Blunders: From Darwin to Einstein - Colossal Mistakes by Great Scientists That Changed Our Understanding of Life and the Universe

Review by Allison Bohac

By Mario Livio

Web edition: June 28, 2013
Print edition: July 13, 2013; Vol.184 #1 (p. 30)

Even brilliant scientists have bad days. Consider chemist Linus Pauling, who described the alpha helix structure of proteins in 1951. When he attempted to do the same for DNA, however, he botched it ? badly. Among other problems, he flubbed the basic chemistry, proposing a structure for deoxyribonucleic acid that wasn?t an acid.

When asked about Pauling?s faulty DNA model, one of his contemporaries commented, ?You could not have written a fictional novel in which Linus would have made an error like this.?

Why Pauling stumbled is just one of the questions that astrophysicist Livio attempts to answer. Countless scientists have made major mistakes over the centuries, but Livio wisely focuses on gaffes from just five great minds: Pauling, Darwin, Einstein, astrophysicist Fred Hoyle and William Thomson, also known as Lord Kelvin.

Livio outlines the scientific context for each scientist?s work and pores
over personal correspondence and historical records to try to explain what went wrong. Hoyle, for instance, stubbornly dismissed the Big Bang model of the universe for decades, and Einstein failed to see the importance of his cosmological constant, which he had devised as a fix for general relativity. Though Livio can only speculate on the reasons behind these errors, his clear and compelling writing reinforces the important contributions each of these men made to their fields.

The double helix may have eluded Pauling, but his mistake helped to galvanize James Watson and Francis Crick into a concentrated effort to find the correct structure. Livio?s ultimate message is that blunders ? even big ones ? can play a role in scientific discovery.

Video game tech used to steer cockroaches on autopilot

June 25, 2013 ? North Carolina State University researchers are using video game technology to remotely control cockroaches on autopilot, with a computer steering the cockroach through a controlled environment. The researchers are using the technology to track how roaches respond to the remote control, with the goal of developing ways that roaches on autopilot can be used to map dynamic environments -- such as collapsed buildings.

The researchers have incorporated Microsoft's motion-sensing Kinect system into an electronic interface developed at NC State that can remotely control cockroaches. The researchers plug in a digitally plotted path for the roach, and use Kinect to identify and track the insect's progress. The program then uses the Kinect tracking data to automatically steer the roach along the desired path.?

The program also uses Kinect to collect data on how the roaches respond to the electrical impulses from the remote-control interface. This data will help the researchers fine-tune the steering parameters needed to control the roaches more precisely.

"Our goal is to be able to guide these roaches as efficiently as possible, and our work with Kinect is helping us do that," says Dr. Alper Bozkurt, an assistant professor of electrical and computer engineering at NC State and co-author of a paper on the work.

"We want to build on this program, incorporating mapping and radio frequency techniques that will allow us to use a small group of cockroaches to explore and map disaster sites," Bozkurt says. "The autopilot program would control the roaches, sending them on the most efficient routes to provide rescuers with a comprehensive view of the situation."

The roaches would also be equipped with sensors, such as microphones, to detect survivors in collapsed buildings or other disaster areas. "We may even be able to attach small speakers, which would allow rescuers to communicate with anyone who is trapped," Bozkurt says.

Bozkurt's team had previously developed the technology that would allow users to steer cockroaches remotely, but the use of Kinect to develop an autopilot program and track the precise response of roaches to electrical impulses is new.

The interface that controls the roach is wired to the roach's antennae and cerci. The cerci are sensory organs on the roach's abdomen, which are normally used to detect movement in the air that could indicate a predator is approaching -- causing the roach to scurry away. But the researchers use the wires attached to the cerci to spur the roach into motion. The wires attached to the antennae send small charges that trick the roach into thinking the antennae are in contact with a barrier and steering them in the opposite direction.

The paper, "Kinect-based System for Automated Control of Terrestrial Insect Biobots," will be presented at the Remote Controlled Insect Biobots Minisymposium at the 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society July 4 in Osaka, Japan. Lead author of the paper is NC State undergraduate Eric Whitmire. Co-authors are Bozkurt and NC State graduate student Tahmid Latif. The research was supported by the National Science Foundation.

Weizmann Institute scientists discover that spontaneously emerging brain activity patterns preserve traces of previous cognitive activity

What if experts could dig into the brain, like archaeologists, and uncover the history of past experiences? This ability might reveal what makes each of us a unique individual, and it could enable the objective diagnosis of a wide range of neuropsychological diseases. New research at the Weizmann Institute hints that such a scenario is within the realm of possibility: It shows that spontaneous waves of neuronal activity in the brain bear the imprints of earlier events for at least 24 hours after the experience has taken place.

The new research stems from earlier findings in the lab of Prof. Rafi Malach of the Institute's Neurobiology Department and others that the brain never rests, even when its owner is resting. When a person is resting with closed eyes that is, no visual stimulus is entering the brain the normal bursts of nerve cell activity associated with incoming information are replaced by ultra- slow patterns of neuronal activity. Such spontaneous or "resting" waves travel in a highly organized and reproducible manner through the brain's outer layer the cortex and the patterns they create are complex, yet periodic and symmetrical.

Like hieroglyphics, it seemed that these patterns might have some meaning, and research student Tal Harmelech, under the guidance of Malach and Dr. Son Preminger, set out to uncover their significance. Their idea was that the patterns of resting brain waves may constitute "archives" for earlier experiences. As we add new experiences, the activation of our brain's networks lead to long-term changes in the links between brain cells, a facility referred to as plasticity. As our experiences become embedded in these connections, they create "expectations" that come into play before we perform any type of mental task, enabling us to anticipate the result. The researchers hypothesized that information about earlier experiences would thus be incorporated into the links between networks of nerve cells in the cortex, and these would show up in the brain's spontaneously emerging wave patterns.

In the experiment, the researchers had volunteers undertake a training exercise that would strongly activate a well-defined network of nerve cells in the frontal lobes. While undergoing scans of their brain activity in the Institute's functional magnetic resonance imaging (fMRI) scanner, the subjects were asked to imagine a situation in which they had to make rapid decisions. The subjects received auditory feedback in real time, based on the information obtained directly from their frontal lobe, which indicated the level of neuronal activity in the trained network. This "neurofeedback" strategy proved highly successful in activating the frontal network a part of the brain that is notoriously difficult to activate under controlled conditions.

To test whether the connections created in the brain during this exercise would leave their traces in the patterns formed by the resting brain waves, the researchers performed fMRI scans on the resting subjects before the exercise, immediately afterward, and 24 hours later. Their findings, which appeared in the Journal of Neuroscience, showed that the activation of the specific areas in the cortex did indeed remodel the resting brain wave patterns. Surprisingly, the new patterns not only remained the next day, they were significantly strengthened. These observations fit in with the classic learning principles proposed by Donald Hebb in the mid-20th century, in which the co-activation of two linked nerve cells leads to long term strengthening of their link, while activity that is not coordinated weakens this link. The fMRI images of the resting brain waves showed that brain areas that were activated together during the training sessions exhibited an increase in their functional link a day after the training, while those areas that were de-activated by the training showed a weakened functional connectivity.

This research suggests a number of future possibilities for exploring the brain. For example, spontaneously emerging brain patterns could be used as a "mapping tool" for unearthing cognitive events from an individual's recent past. Or, on a wider scale, each person's unique spontaneously emerging activity patterns might eventually reveal a sort of personal profile highlighting each individual's abilities, shortcomings, biases, learning skills, etc. "Today, we are discovering more and more of the common principles of brain activity, but we have not been able to account for the differences between individuals," says Malach. "In the future, spontaneous brain patterns could be the key to obtaining unbiased individual profiles." Such profiles could be especially useful in diagnosing or learning the brain pathologies associated with a wide array of cognitive disabilities.

Averting worse economic collapses

June 25, 2013 ? By managing macro-economic parameters, scientists believe that -unlike previously thought- it is possible to steer an economy around irreversible changes in its complex dynamics and avert potential economic disasters. These findings, about to be published in The European Physical Journal B, stem from the theoretical work of Michael Harr? and colleagues at the Complex Systems Group at the University of Sydney, Australia.

Physicists have a long experience of using statistical mechanics to study equilibrium points and small fluctuations in large numbers of interacting particles under varying pressure and temperature conditions. By applying statistical-mechanics methods to economic game theory, it is possible to describe the strategic interactions between, say, businesses which are influenced by their own incentives as well as the incentives of third parties.

By changing a macro-economic parameter like tax rates, previous research has shown the system will usually move away a little from where it had settled, but not much. Their new results show that such optimisation can produce a tipping point where a change in the tax regime, for example, will cause the whole economy to suddenly collapse.Harr? and colleagues found that it is possible to find a steady state in the specific scenario where the contributions each business makes to the whole economy are maximised in terms of financial return. And even if an economy is drifting inexorably towards a tipping point, they showed that small perturbations of the system parameters can move an economy around a tipping point, thus averting it.

The ability to exert control on economies depends on having sufficient control of the system parameters -potentially addressed by empirical research, and knowing where the economy is relative to these tipping points- provided by recent measuring techniques.

Paula Deen re-scheduled for 'Today' on Wednesday

NEW YORK (AP) ? Paula Deen will appear on NBC's "Today" show on Wednesday, according to host Matt Lauer.

Lauer's announcement came Monday, three days after the celebrity cook abruptly canceled on the morning show, where she was scheduled to answer questions about her past use of racial slurs.

Lauer said Deen "told us she will be here this time."

While questioned last month in a discrimination lawsuit, the 66-year-old Food Network star admitted to using the N-word in the past, but she insisted she and her family do not tolerate prejudice.

Deen issued videotaped apologies Friday afternoon seeking forgiveness from fans and critics.

But hours later, the Food Network announced it wouldn't renew her contract when it ends this month.

(AP) ? Aerialist Nik Wallenda's tightrope walk over a gorge near the Grand Canyon drew nearly 13 million viewers to the live television broadcast.

The Discovery Channel said Monday that the quarter-mile stunt at the Little Colorado River Gorge was among the most highly viewed shows in the station's history.

It also prompted 1.3 million tweets Sunday, making it one of the top trending topics.

Wallenda took 22 minutes to cross the 2-inch-thick steel cable, 1,500 feet above the dry river bed. He did it without a harness or safety net.

The well-known daredevil contended with the wind and repeatedly called on God to calm the swaying cable.

He wore a microphone and two cameras, one that looked down on the river bed and one that faced straight ahead.

Syrian regime, rebels step up offensives

BEIRUT (AP) ? Syrian government forces stepped up their attack against rebel strongholds north of the capital, Damascus on Saturday, while opposition fighters declared their own offensive in the country's largest city Aleppo.

The fighting in Damascus came as the Syrian government announced salary increases for state employees and members of the military, days after the Syrian currency dipped to a record low of 210 pounds to the dollar compared with 47 when the crisis began more than two years ago. The raise also covered pensions.

Both sides intensified operations as an 11-nation group that includes the U.S., dubbed the Friends of Syria, began meeting in Qatari capital of Doha to discuss how to coordinate military aid and other forms of assistance to the rebels seeking to oust Syrian President Bashar Assad.

The donors agreed on Saturday to do more to help the embattled rebels trying to overthrow Assad, U.S. Secretary of State John Kerry said. While he offered no specifics, Kerry said the assistance would help change the balance on the battlefield. Kerry also denounced Assad for inviting Iranian and Hezbollah fighters to fight alongside his troops, saying the Syrian president risked turning the civil war into a regional sectarian conflict.

Activists, meanwhile, reported heavy shelling of many districts north of Damascus, apparently an attempt to cut links between rebel-held districts that have served as launching pads for operations against the capital. Three children, including two from the same family, have been killed in shelling of the outlying district of Qaboun since Friday, according to the Britain-based Syrian Observatory for Human Rights, which relies on an extensive network of activists in Syria.

The Lebanese TV station Al-Mayadeen, which had a reporter embedded with Syrian government forces in the offensive, quoted a military official as saying that the operation aims to cut rebel supply lines, separate one group from another and secure the northern entrances to the capital. The regime's forces have struggled for months to regain control of these suburbs.

The Observatory said the neighborhood was being attacked from several different sides, while the shelling has caused structural damage and started fires. Activists from Qaboun posted on Facebook that government forces had deployed new tanks to reinforce its positions outside the neighborhood, and the bombardment had brought buildings down.

The Observatory said rebels targeted a police academy in the nearby Barzeh area Saturday, pushing back against a government attempt to storm the neighborhood. One rebel was killed in overnight fighting, it said.

State news agency SANA said troops "inflicted heavy losses" among rebels in several suburbs of Damascus.

The uprising against Assad began in March 2011 as peaceful protests but morphed into a civil war as rebels took up arms against a government crackdown. The Syrian regime has gained momentum in recent weeks with the help of Iran and its proxy group Hezbollah. The opposition is hoping the Obama administration's decision to begin supplying them with arms will help swing the tide in their favor.

Rebels say they have already received new weapons from allied countries? but not the U.S. ? that they claim will help them to shift the balance of power on the ground. Experts and activists said the new weapons include anti-tank missiles and small quantities of anti-aircraft missiles.

It was not clear if any of the new weapons have made it to the Damascus area. A spokesman for one of the main groups fighting outside of Damascus, the al-Islam brigade, said his group had none of the new weapons. The spokesman, who declined to be named for fear of government reprisals, spoke to The Associated Press on Skype.

He said government forces were shelling Barzeh from Qasioun mountain overlooking Damascus. Syria's main Western-backed opposition group said Thursday that 40,000 civilians in the two northern districts of Damascus are suffering from shortages of food and medical supplies.

Rebels and government also clashed in and around the northern city of Aleppo, where government forces launched an offensive earlier this month. Activists reported clashes in southern and western neighborhoods.

The Observatory also said rebels pounded a military academy in the area, causing a fire in the compound. No casualties were immediately reported. In Rashideen, rebel forces have pushed government forces out from parts of the neighborhood, according to the local Aleppo Media Center network and posts on Facebook.

A statement by a coalition of rebel groups, posted on the Center's page, declared that the fighters are launching a new operation to seize control of the western half of Aleppo.

Also Saturday, Syrian forces fired a dozen shells that landed in a northern Lebanese border town, causing a panic among residents, the Lebanese news agency reported.

SANA said government troops were targeting a group of infiltrators across the border. It gave no further details.

Rockets from Syria fall regularly into towns and villages near the border.

In Damascus, a presidential decree said that the raise for the public sector could reach up to 40 percent depending on the salary of the civil servant. Pensions could rise by up to 25 percent, according to the decree.

It said those who make 10,000 pounds ($54) a month will get a 40 percent raise, while those who make double that amount will get a 20 percent boost. People making 40,000 pounds a month will get a 5 percent raise, it said.

Citrix Systems co-founder dies in Florida

BACO RATON, Fla. (AP) -- Citrix Systems co-founder Edward Iacobucci has died in South Florida. He was 59.

The VirtualWorks Group reports that Iacobucci died at home Friday morning after a 16-month battle with pancreatic cancer.

Iacobucci graduated from Georgia Tech with an engineering degree and got a job working for IBM in 1979. He left IBM in 1989 to co-found Citrix Systems, Inc., where he served chairman and chief technology officer through all of its market and product development phases. He retired in 2000.

In 2002, Iacobucci co-founded DayJet Corporation, which ceased operations in 2008. But a year later, he co-founded VirtualWorks Group, headquartered in Boca Raton, to help customers organize their information. He served as president and CEO there until last month, when he stepped down for health reasons.

Germany protests over Turkish minister's comments

BERLIN (AP) ? Germany's Foreign Ministry has summoned the Turkish ambassador to hear a protest after Turkish minister accused Chancellor Angela Merkel of picking on Turkey for domestic political gain ahead of elections.

Merkel on Monday criticized the Turkish security forces' crackdown against street protests as "much too strong." The chancellor has long been skeptical of Turkey's ambitions to join the European Union; her coalition government supports continuing membership talks but this week blocked a decision to open a new chapter in negotiations.

Egemen Bagis, Turkey's minister in charge of EU affairs, said that if Merkel is looking for "internal political material" ahead of September elections "this should not be Turkey."

German Foreign Ministry spokesman Andreas Peschke said ambassador Huseyin Avni Karslioglu was summoned to the ministry Friday.

Two Planes In Near Miss Over New York - Business Insider

The Federal Aviation Administration is investigating after two planes came perilously close to each other in a near miss over New York City on June 13, the Associated Press reports.

The incident happened around 3.45pm when a Delta Airlines Boeing 747 landing at John F. Kennedy International Airport came close to a Shuttle America Embraer E170 departing from LaGuardia Airport.

In a statement released today the FAA said the planes were "turning away from each other at the point where they lost the required separation." The issue occurred after the Delta flight had missed an approach and ended up traveling in the same direction as the Shuttle America flight.

One federal official told NBC New York that the two planes had come within 200 feet of each other.

NBC New York also got hold of a recording of the air traffic control contacting the planes, which is notable for how calm everyone involved sounds. Listen below (at around 0.30 in):

World Food Prize goes to 3 biotech scientists

DES MOINES, Iowa (AP) ? The World Food Prize Foundation on Wednesday took the bold step of awarding this year's prize to three pioneers of plant biotechnology whose work brought the world genetically modified crops.

The private nonprofit foundation, which is in part funded by biotechnology companies, refused to shy away from the controversy surrounding genetically modified crops that organic food advocates say are harmful to people and the environment.

"If we were to be deterred by a controversy, that would diminish our prize," said the foundation's president, Kenneth Quinn, a retired U.S. diplomat.

This year's award goes to Marc Van Montagu, founder and chairman of the Institute of Plant Biotechnology Outreach at Ghent University in Belgium; Mary-Dell Chilton, founder and researcher at Syngenta Biotechnology; and Robert Fraley, chief technology officer at Monsanto.

Van Montagu and Chilton independently developed the technology in the 1980s to stably transfer foreign genes into plants, a discovery that set up a race to develop tools to genetically engineer plants. It allowed other scientists to incorporate genetic traits in plants to better withstand drought, extreme heat and to fight off pests and disease. Fraley was the first to successfully transfer immunity to specific bacteria into a plant.

Fraley genetically engineered the first herbicide-resistant soybean in 1996.

The foundation lists Monsanto and Syngenta Foundation among its annual donors, along with other agribusiness corporations such as DuPont Pioneer, Archer Daniels Midland Co. and Cargill.

The award drew immediate condemnation from opponents of corporate farming.

"We could not ask for a better poster child for what's wrong with the prize than the recipients of this year's World Food Prize," said Frank Cordaro, who organized an Occupy World Food Prize protest last year. "It's all part of the very same system of the corporate elite. The problem is not with the recipients, the problem is with the system that gives the 1 percent all the power and corporate agriculture is built on that system."

Genetically enhanced crops are grown on more than 420 million acres in nearly 30 countries by over 17 million farmers worldwide, the foundation said. More than 90 percent are small, resource-poor farmers in developing countries.

Many U.S. farmers credited genetic modifications in corn with saving last year's crop from all but total devastation as half of the nation endured the worst drought in 60 years. Modern corn plants are more stable and can withstand a wider variety of climate conditions because of genetically improved leaves, roots and reproductive capability.

Fraley said biotechnology will enable the farming industry to meet the needs of a growing global population.

"We know we need from a demand perspective to double food production around the world in the next 30 years," he said.

Some organic farmers warn that widespread planting of genetically modified crops could contaminate organic and traditional crops, destroying their value. Others are concerned about the uncharted long-term impact for those who eat products such as milk and beef from animals raised on genetically modified plants.

"GMO crops have led to the loss of food security worldwide and for small farmers, they have led to the development of factory farms and have destroyed biodiversity in food we do produce and consume," said David Goodner, a community organizer for Iowa Citizens for Community Improvement, an environmental and human rights activist group that opposes corporate farming. "The World Food Prize by selecting these people to honor shows that it cares more about corporate profits than it cares about truly feeding the world with healthy food."

Van Montagu said the food prize award should raise understanding of the safety of genetically modified crops.

"We just have to explain to society the science fact and that is not the slightest risk has been identified. These crops are as safe, if not safer, than food that comes from traditional agriculture," he said. "If somebody denies that we bluntly can say they are misinformed."

The World Food Prize was created in 1986 by Norman Borlaug, winner of the Nobel Peace Prize for his efforts to fight hunger. Borlaug was honored in 1970 for work that boosted agricultural production in what has become known as the "Green Revolution."

Recipients will receive the prize, which includes $250,000, at a ceremony in October at the Iowa Capitol in Des Moines attended by hundreds of scholars and agribusiness leaders from around the world.

FGF21 hormone, key to control obesity, also protects against heart diseases in mice

June 17, 2013 ? A research group has found that FGF21, an endocrine factor which reduces glucose levels, protects against cardiac diseases in mice.

The research, published online on the journal Nature Communications, was led by Francesc Villarroya, professor from the Department of Biochemistry and Molecular Biology of the UB and Director of the Institute of Biomedicine of the University of Barcelona (IBUB), affiliated centre with the campus of international excellence BKC. Anna Planavila, first author of the paper, from that Department of the UB, the experts Luigi Gabrielli and Marta Sitges (IDIBAPS-Hospital Cl?nic de Barcelona) and other international experts also collaborated in the research.

Fibroblast growth factor 21 (FGF21), mainly secreted by the liver, is a protein which acts as a metabolic regulator and plays a key role as an antidiabetic and antiobesity agent. In 2010, the cover of the journal Cell Metabolism echoed a finding made by the UB research group headed by Dr Villarroya: FGF21 activates thermogenesis in brown adipose tissue -- which governs energy expenditure and heat production in the body -- , what promotes the burning of calories to release heat, dissipating then large amounts of energy.

FGF21: a cardioprotective agent in mice

According to Professor Francesc Villarroya, member of the Biomedical Research Networking Centres on Physiopathology of Obesity and Nutrition (CIBERobn), "the research has contributed to describe the protecting role against cardiac hypertrophy that FGF21 plays in mice." The research group compared the role of FGF21 in cardiac tissue in a group of knockout mice (those lacking FGF21) and in another group which perfectly express the factor. They observed that mice lacking FGF21 are more prone to develop cardiac diseases.

Anna Planavila, expert on metabolism and cardiac functions study, explains that "echocardiography tests, carried out together with a group from Hospital Cl?nic, proved how knock-out mice's heart function had got worse as they showed dilatation and cardiac hypertrophy, electrocardiography waves due to alterations of the mechanisms of cardiac systole and diastole mechanisms, etc. These effects were also observed at histological and gene expression levels."

The heart is able to produce FG21

Besides FGF21 new function, the paper reveals new scientific findings about cardiac metabolism and physiology. Authors affirm that the heart is also able to produce this factor which works as a protective agent against heart stress situations.

"Previous knowledge." Villarroya adds, "had already stated that FGF21 is synthetized by the liver, the skeletal muscle and the brown adipose tissue to speed up glucose uptake and energy metabolism. The research has also unveiled that the cardiac muscle produces the endocrine factor too."

Experts state that the heart produces the factor under basal conditions. If the heart undergoes more physiological stress, FGF21 production is increased as a protective response. "Unlike the liver, the skeletal muscle and the brown adipose tissue, cardiac cells ability to produce this factor has a local and self-protection effect," Villarroya remarks. The pre-clinical study published on Nature Communications shed new light on the metabolic control of molecular signalling pathways of diabetes, obesity and adipose tissue inflammation. The research can contribute to establish FGF21 as a potential tool in the development of new strategies to prevent and treat cardiac damage.

Governor Morton's 'Finance Bureau' - NYTimes.com

Disunion follows the Civil War as it unfolded.

President Abraham Lincoln once said that Oliver P. Morton, Republican governor of Indiana, was a ?good fellow? but ?the skeeredest man I know of.? Morton had just written him a panicked letter about the results of the October 1862 state elections; Democrats had swept the contest, overwhelmingly winning the state offices and 7 of the 11 Congressional districts. They would now control both houses of the State Legislature by wide margins, threatening Morton?s control of the state?s war effort.

In response, Morton asked for federal aid to help secure the Indiana public?s support of the Union. And Lincoln, his personal opinion of Morton aside, did something surprising: he allowed the governor to establish a finance bureau that had no legal or constitutional basis.

The arrangement was unprecedented, but it worked to both Lincoln and Morton?s advantage. The historian William B. Hesseltine chronicled the ?clash of personalities? between the president and several Northern governors, including Morton, who sought to preserve their prerogatives, essentially their states? rights, against the centralizing tendencies of the wartime federal government. But Hesseltine argued that ?with many a skillful maneuver,? Lincoln ?proved that he alone could direct the war? ? by helping Morton shore up his own base in Indiana, he also tied the state even closer to the federal government.

Morton was Indiana?s first governor to be born in the state. A former Democrat, he had practiced law in Centerville. How or why he became a Republican is unclear: during the 1840s and ?50s, he had opposed antislavery positions within the Democratic Party; objected to renewing agitation over slavery; and accepted the Compromise of 1850, including its proslavery provisions. But by 1856, Morton had broken with the Democrats and joined the Republicans. As with many positions Morton took during his political career, historians have been unsure whether he acted from principle or opportunism.

Whatever the reason, Morton?s conversion served his career well. He ran unsuccessfully for governor in 1856 as a candidate for the People?s Party, as the Republicans were then called in Indiana. But four years later, he ran for office as lieutenant governor ? even though everyone knew that if Republicans gained control of the statehouse, the new majority would pick the gubernatorial candidate, Henry S. Lane, as a senator, whereupon Morton would ascend to the governorship. This is indeed what happened: Morton spent only two days as lieutenant governor.

Morton aggressively embraced his newfound Republican identity. During the secession crisis, Indiana?s departing governor, the Democrat Abram Hammond, had urged attempts to address Southern grievances. Even Lane, among the most radical of Republicans, had counseled ?conciliation? toward the South. But Morton would have none of this. Taking office as governor, he began to prepare for war. He tirelessly recruited troops, helping to make Indiana second only to Kansas in the percentage of military-age men who served three years in the Union Army. After the firing on Fort Sumter, Morton offered President Lincoln 10,000 men from Indiana alone, a significant proportion of the 75,000 that the president had called up from the entire country. Morton not only sent agents to purchase supplies for Indiana troops, including weapons and uniforms, but he also established a state arsenal to manufacture munitions.

And Morton earned the appellation the ?Soldier?s Friend? for his solicitous care of Hoosiers in the army: he visited them in camp, on the battlefield and in the hospital, and he insisted that donations from Indiana for the troops be funneled to Hoosier soldiers.

He also fought on the political battlefield. Upon taking office, Morton had made efforts to bring Hoosier Democrats into support of the war effort, and even appointed prominent Democrats to military posts. But increasingly, the state?s Democratic Party chose to oppose him. Indiana Democrats were especially disinclined to compromise after they gained a majority in the Legislature in the 1862 elections, which convinced them that voters had repudiated Morton?s war policies. Underestimating Morton?s capacity for a fight, some even expected the governor to resign.

In turn, Morton suspected that the newly elected Democrats were disloyal and might even try to take Indiana into the Confederacy ? fears that he confided to President Lincoln in a letter written shortly after the state elections. When the legislative session began in January 1863, Democrats rejected Morton?s message, preferring to endorse the opinions of Horatio Seymour, the Peace Democrat governor of New York.

Heavily outnumbered in the statehouse, Republicans first bolted ? that is, refused to show up for the session ? in an unsuccessful attempt to prevent the election of Democrats as United States senators. Anti-war Democrats introduced resolutions expressing their view that the war was ineffective as a measure to restore the Union. These resolutions did not make it to the floor for debate and so posed little threat. But other resolutions condemned the Lincoln administration?s violations of civil liberties, the issuance of the Emancipation Proclamation and the enactment of the draft. The Legislature even investigated the governor?s bank accounts, but could find no financial irregularities.

Still, it took other measures to disempower Morton: besides reorganizing the Board of Benevolent Institutions to give Democrats control of the charitable relief so important to soldiers? families, the Legislature discussed an armistice and a convention to restore the Union, which Republicans feared would make concessions to the Confederacy.

Again and again, Republicans broke the quorum in the Legislature to block what a legislator from Lafayette called ?all treasonable Legislation.? In late January, state troops deployed around the statehouse, evidently to intimidate the Democrats. The breaking point came, however, when Democrats introduced a militia bill that would have stripped military power from the governor. Rather than leave the militia under Morton?s control, the Legislature wanted to commission officers, make policy for the militia and create a four-man board to raise troops. Republicans called this a ?treasonable conspiracy? and again bolted the session.

They fled to Madison, Ind., which sits on the Ohio River opposite Kentucky, where they planned to flee if the sergeant-at-arms came for them. The Republicans were ready to come back if Democrats would drop their obnoxious measures. Democrats, meanwhile, compared the Republican bolt to Southern secession and expected that the Republicans would have to return to pass an appropriations bill. Instead, the session expired without providing funding for the state government. Democrats then expected that the governor would be forced to call a special session, which Republicans feared that Democrats would exploit ?to consummate their schemes of revolution.?

With his state in a deep political crisis, Morton chose not to call the Legislature into session ? but he still had to pay the state?s bills. The state auditor, who was also a Democrat, refused to issue funds to the governor, arguing that the state treasury could not issue them without a specific legislative appropriation. The Indiana Supreme Court, also dominated by Democrats, ruled in the auditor?s favor.

And so, on his own authority ? but with Lincoln?s blessing ? Morton borrowed from bankers in New York to finance the state government. The governor appealed to private citizens and Republican officials for money to run the state, receiving over $1 million from bankers, corporations and local governments. Secretary of War Edwin M. Stanton provided $250,000 in War Department funds to Indiana from monies intended for states threatened with rebellion. Morton could not deposit the funds he received in these extra-legal ways into the state treasury, because the state treasurer was also a Democrat and might deny him access to the money. So he kept the money in his office safe ? which he referred to as his ?Bureau of Finance.?

Democrats accused Morton of acting like a dictator. Judge Samuel E. Perkins of the Indiana Supreme Court derided the governor for keeping ?the public treasure of the state? in his ?breeches pocket ? or in his illegal bureau of finance,? and even compared Morton to Caesar and Cromwell. Historians have agreed in condemning Morton?s actions: Frank Klement wrote that ?constitutional government collapsed in Indiana? during the period of Morton?s finance bureau.

In January 1865, a new State Legislature, dominated by Republicans, took office. W.H.H. Terrell, Morton?s military secretary, who had supervised the Bureau of Finance, submitted its expenditures to a joint legislative committee. The committee approved the expenses and the Legislature passed a bill appropriating money to repay the New York bankers at 7 percent interest. Morton?s 19th-century biographer, William Dudley Foulke, points out that Morton took a great risk in bypassing a state appropriation: had a future Legislature not upheld his actions, he might have been held personally liable for the money he borrowed. In his letter thanking Secretary of War Stanton, Morton wrote that Stanton had been ?endowed ? with soul and ability to comprehend the times and grapple with the great questions presented.?

Stanton could be forgiven for looking twice at that statement: Morton so often chided the federal government, particularly the War Department, for its slowness and inefficiency that Hesseltine called the governor ?an irritating goad? to the Lincoln administration. It is among the many quirks of the Civil War that a man once solidly in line with the Democrats would, by the middle of the war, not only fall in line behind the president, but work with him to entrench federal power in his state.

Historians have often pointed to the ways in which the Lincoln administration skirted constitutionality. Early in the war, reacting to Chief Justice Roger B. Taney?s order that he had unconstitutionally suspended the writ of habeas corpus, Lincoln asked, ?Are all the laws, but one, to go unexecuted, and the government itself go to pieces, lest that one be violated?? Morton?s actions in creating the Bureau of Finance may have been illegal and unconstitutional, but the governor, as well as the president, earnestly believed that such steps were necessary to the times and great questions of civil war.

Revolutionary technique lets scientists 'see' with sound ? underwater

With a powerful acoustic transmitter and receiver, researchers can take detailed and almost instantaneous pictures of ocean waves, currents, and the underwater structure of the sea.?

The uppermost reaches of the ocean could be rapidly scanned in groundbreaking high detail using acoustic techniques, researchers say. The method resembles that employed to probe the deep Earth.

For more than a century, geologists have used sound waves to investigate?Earth's interior, analyzing how these waves reflect off different layers of rock. Recently, such?seismic imaging?has become commonly used by oceanographers. They employ the technique to analyze fine-scale ocean structures ? thin layers of water only 3 feet (1 meter) or so thick that vary in temperature and?salinity (salt content). These layers can pop up in currents, swirls and the boundaries separating currents or masses of water.

Until now, most seismic imaging of the ocean focused on depths below 500 feet (150 m). This is because structures further up in the water reflect sound only weakly, and there are many sources of noise in shallow depths that can muddle analyses, such as shipping vessels or the breaking of waves. Still, many valuable insights about the ocean waters closest to most human activity potentially awaited scientists who could seismically image shallow waters.

Now marine geophysicist Helen Pi?t? at the University of Brest in France and her colleagues have devised a way to scan the upper ocean at depths of 30 to 500 feet (10 to 150 m).?

"These results are very exciting, not only because they provide the first actual imaging of shallow oceanographic structures, but also because they [are the] result of many unsuccessful attempts," Pi?t? told LiveScience.

Beating the odds

One key factor in the research team's strategy to image the upper ocean is a powerful transmitter of acoustic energy. Another is a receiver that can pick up multiple channels of sound, to help overcome interference from ambient noise. The scientists also made sure the acoustic wavelengths they used matched the thickness of the ocean features they investigated.

A major challenge the researchers faced was that many of the technical aspects of the device's design had contradictory requirements, calling for a series of compromises to make things work.

"When we started working on this project, many people were very skeptical about our chances," Pi?t? said.

The scientists tested their system on the continental shelf off western Brittany in France. From April to October, the warmer upper waters and the colder lower depths at this location become separated by a layer of water known as a thermocline.

"It took us almost four years and four scientific cruises to set up and test the device that we used for this study," Pi?t? said.

Report: Slowdown in health care costs to continue

WASHINGTON (AP) ? There's good news for most companies that provide health benefits for their employees: America's slowdown in medical costs may be turning into a trend, rather than a mere pause.

A report Tuesday from accounting and consulting giant PwC projects lower overall growth in medical costs for next year, even as the economy gains strength and millions of uninsured people receive coverage under President Barack Obama's health care law.

If the calculations are correct, cost spikes because of the new health care law should be contained within a relatively narrow market segment. That would come as a relief for Democrats in an election year during which Republicans plan to use criticism of "Obamacare" as one of their main political weapons.

"There are some underlying changes to the system that are having an impact, and we can expect lower increases as we come out of the recession," said Mike Thompson of PwC's Health Research Institute, which produced the study. Cost "is still going up, but not as much as it used to."

The report comes with a caveat that sounds counterintuitive at first: Self-employed people and others who buy coverage individually could well see an increase in premiums in 2014.

The reasons have to do with requirements in the health care law. For example, starting next year insurers must accept patients with pre-existing medical problems, who cost more to cover. Also, new policies have to provide a basic level of benefits more generous in some cases than what's currently offered to individual consumers.

About 160 million workers and family members now have job-based coverage and are less likely to be affected. The individual market is much smaller, fewer than 20 million people. Still, it's expected to grow significantly over the next few years as a result of the health care law, which will also provide tax credits to help many people afford their premiums.

The U.S. spends more than $2.7 trillion a year on health care, well above any other developed country. But quality is uneven, there's widespread waste and fraud, and the system still leaves about 45 million people uninsured.

For years U.S. health care spending has grown much faster than the overall economy and workers' wages, but since the recession those annual increases have slowed dramatically. The debate now is whether that's a continuing trend. The answer will be vitally important, not only for companies and their employees, but for taxpayers who foot the bill for government programs such as Medicare, Medicaid and Obama's coverage expansion.

PwC's report forecasts that direct medical care costs will increase by 6.5 percent next year, one percentage point lower than its previous projection. The cost of care is the biggest component of premiums, followed by administrative expenses and overhead.

Cost-shifting to workers and efficiency measures from employers got most of the credit for slowing growth. PwC also said the health care law's push for hospitals and doctors to be more accountable may be starting to have an impact.

Four big factors were seen as pushing costs down next year:

?Patients seeking more affordable routine services in settings like clinics springing up in retail stores, as opposed to a doctor's office or the emergency room.

?Major employers contracting directly with hospital systems that have a proven record for complicated procedures such as heart surgery and certain back operations.

?The government ramping up penalties on hospitals that have too many patients coming back with problems soon after being discharged.

?Employers' ongoing effort to shift more costs to workers through higher annual deductibles, the amount people must pay each year before insurance picks up.

By using such shifting, PwC estimates that employers may be able to drive their share of next year's cost increase even lower than 6.5 percent.

On the other hand, two big factors will push costs upward:

?The high price of new "specialty" drugs to treat serious chronic illnesses such as autoimmune diseases and some types of cancer.

?Industry consolidation, with big hospitals buying up smaller ones, as well as medical practices and rehab centers. The downside of the demand for greater efficiency by employers and government is that it may be fostering new health care monopolies.
