How Data Beats Intuition at Making Selection Decisions
A recent meta-analysis by Kuncel, Klieger, Connelly and Ones found that, across multiple criteria in work and academic settings, when people combined hard data with their judgments, and those of others, their predictions were always less valid, and less predictive of real outcomes, than those generated by hard data alone.

“To know that we know what we know, and that we do not know what we do not know, that is true knowledge,” Confucius once said. Algorithms using objective data lead to much greater accuracy in predicting widely valued outcomes such as job and academic performance. A true expert is someone who knows what they do not know—namely, that our intuition can fail us.

Fatal toxins found in ‘edible’ wild mushrooms
A wild mushroom eaten by foraging enthusiasts across Europe has been found to contain dangerous and potentially lethal toxins. Chinese scientists believe they have identified the mushroom toxins that cause rhabdomyolysis – a sometimes fatal disease that can irreparably damages the kidneys – that was first reported 15 years ago in France. However, the toxins were not isolated from the mushroom Tricholoma equestre that was thought to be responsible for the deaths, but from Tricholoma terreum, its close relative, highlighting the complexity of fungus toxicology. These scientists are recommending that people who forage for mushrooms avoid eating both of these species.
The two new compounds are of medium toxicity, so it is possible that they work together, perhaps with other unknown mushroom toxins, in a cumulative way to cause lethal rhabdomyolysis.
A person would have to eat a portion of T. terreum every day for several days before the dose would be deadly. He says that it is fortunate that T. terreum, prized for its flavour, is only eaten in small quantities or there might have been more fatalities.
A combination of three types of mushroom toxins may have been responsible for more than 200 deaths in China.

 Antimatter: Have you ever heard about Antimatter? You may have probably not heard of it much. Antimatter is basically a mirror image of existing matter and it is very difficult to make. This can be created by physicists at the world’s largest particle accelerator called the Large Hadron Collider, near Geneva, Switzerland. This material is scarcely available, only about a billionth of a gram can be made per year. It is so rare that even its potential uses are still largely not known. One of its explored uses is that antimatter shows some possibility of practical application in treating cancer. Not only can it be used as medicine, it can also be possibly used to fuel spaceships to the planets in future. Its price is nearly $62.5 trillion/gram.

 Californium 252: Californium is a radioactive transuranic element with its atomic number as 98 is a man-made element. It was discovered in 1950. It was created by scientists by bombarding the chemical element curium with alpha particles which resulted into a radioactive material. There are almost ten known versions, or isotopes of this material that exist. Few of its uses include treating certain forms of cancer and detecting gold and silver in ore or oil at the bottom of a well. It is true that californium is artificially made on Earth, but it is also said that certain stars that explode as super-novae may produce californium in space too. The actual price of californium is $27 million/gram.

10 Scientific Ideas That Scientists Wish You Would Stop Misusing
http://io9.com/10-scientific-ideas-that-scientists-wish-you-would-s...

There is a difference in using words in science and art/literature. In art and literature perceptions differ from person to person depending on the region , culture etc. people are associated with and therefore usage can also differ. But in science the perception is based on facts and there can be only one fact given the conditions in which it is sought are same. You cannot give several names to it.  I think science has a universal language unlike other subjects. Therefore one has to follow it to avoid misconceptions.

The United Nations will seek ways to toughen environmental laws this week to crack down on everything from illegal trade in wildlife to mercury poisoning and hazardous waste.

The UN environment assembly (UNEA), a new forum of all nations including environment ministers, business leaders and civil society, will meet in Nairobi from June 23-27 to work on ways to promote greener economic growth.

That drive includes giving environmental laws more teeth.

The calorie free sweetener erythritol is widely used in Asia; it is also gaining popularity in Europe and America. At the Vienna University of Technology, a new cheap method has been developed to produce erythritol from straw with the help of mould fungi.
Erythritol has many great advantages: it does not make you fat, it does not cause tooth decay, it has no effect on the blood sugar and, unlike other sweeteners, it does not have a laxative effect. In Asia it is already widely used and it is becoming more and more common in other parts of the world too. Up until now, erythritol could only be produced with the help of special kinds of yeast in highly concentrated molasses. At the TU Vienna, a method has now been developed to produce the sweetener from ordinary straw with the help of a mould fungus. The experiments have been a big success, and now the procedure will be optimized for industry.

From Straw via Sugar to Erythritol
Straw is often considered to be worthless and is therfore burnt, but it can be a precious resource. Some of its chemical components can be made into valuable products. First, the finely chopped straw has to be “opened up”: with the help of solvents, the cell walls are broken, the lignin is dissolved away. The remaining xylan and cellulose are then processed further.
“Usually the straw has to be treated with expensive enzymes to break it down into sugar”, says Professor Robert Mach (Vienna University of Technology). “In highly concentrated molasses, special strains of yeast can then turn the sugar into erythritol, if they are placed under extreme osmotic stress.”
Mould Fungus Makes Intermediate Step Obsolete
The enzymes opening up the straw can be obtained with the help of the mould fungus Trichoderma reesei. This kind of mould also plays the leading role in the new production process developed at the Vienna University of Technology.

Two big advantages have been achieved by genetically modifying the fungus: the process of obtaining the enzymes from mould cultures and chemically cleaning them used to be cumbersome – now the improved strain can be directly applied to the straw. Secondly, the mould can now produce erythritol directly from the straw. The intermediate step of producing molasses is not necessary any more and no yeast has to be used.

New Neurons In the Brain Keep Anxiety at Bay
The adult brain generates neurons every day. These cells help us to distinguish one memory from another—a finding that could lead to novel treatments for anxiety disorders

A study in the journal Cell reveals that a significant number of new neurons in the hippocampus — a brain region crucial for memory and learning — are generated in adult humans.

“It was thought for a long time that we are born with a certain number of neurons, and that it is not possible to get new neurons after birth,” says senior study author Jonas Frisén of the Karolinska Institute.

By Carbon-dating neurons the researchers measured the carbon-14 concentration in DNA from  the hippocampal neurons of deceased humans. They found that 1,400 new neurons in the dentate gyrus.area are added each day — 1.75% per year — during adulthood, and that this rate declines only modestly with age, suggesting that adult hippocampal neurogenesis may contribute to human brain function.

'Biggest prize in science' announced
The Breakthrough Prizes are awarded for recent achievements in fundamental physics, life sciences and mathematics.

The organisers describe them as the "biggest science awards in the world" as they offer the most prize money - $3m (£1.76m) for each.
such awards were important because they help to attract the "the best brains into science".

"Science has an undeserved reputation of being dry and unglamorous so anything that can be done to change that image is to be welcomed.
The Breakthrough Prizes were launched by a group of philanthropic technology billionaires including Sergey Brin, co-founder of Google, and Mark Zuckerberg, CEO of Facebook, Jack Ma, founder of Alibaba Group, and Yuri Milner, founder of investment firm Digital Sky Technologies.

Mr Milner said the aim of the prize was to "cultivate a positive image of science and rationalism, and an optimistic view of humanity's future".

"Outside the field of entertainment, intellectual brilliance is under-capitalized in our society. 58 years ago, one of the most famous men on earth was not an actor, athlete or musician, but a theoretical physicist. Albert Einstein's face was on magazine covers, in newspapers and on television, worldwide,"
His name was synonymous with genius. Yet most of today's top scientists - despite opening new windows onto the Universe, curing intractable diseases and extending human life - are unknown to the general public. The greatest thinkers of our age should be superstars, like the geniuses of screen and stadium."

With Prizes Like This, Who Needs a Nobel?

Tech titans  to make winners of the 'Oscars of science' into instant millionaires - but is it the right thing to do?
Silicon Valley hosts lavish ceremony for Breakthrough prize that aims to give scientists celebrity status and inspire interest in life's 'big questions'.

Now a handful of billionaire engineers have turned their attention to a social blight that affects their own kind: the lack of appreciation (and funding) for scientists.

This is among the most lucrative awards in science, almost triple the size of the Nobel prize, and bigger than the $1.7m Templeton prize. It's expected to be bigger and bolder than the last similar ceremony.

Breakthrough prize and the Fundamental Physics prize

with focus on the very short-term problems that have an immediate impact on our lives.

It's easy to see why science has struggled to get the public recognition it deserves till now: much of it goes over everyone's heads.

With the right combination of celebrity endorsement and cash, scientists touting the most complex theories can become modern-day celebrities - making people realize the importance of science.

However, there is criticism too:

Perhaps not surprisingly, Milner's prizes have come under some criticism from scientists and even a few Nobel prizewinners, who claim they benefit the egos of their founders more than anything else. They are, says one physicist quoted in Nature magazine, "buying the prestige of Nobel". After scientist Alexander Polyakov received his orb-like Fundamental Physics prize from Morgan Freeman last March, and instantly became a millionaire, he told Nature backstage that it was all an "interesting experiment. Such big prizes could have a positive impact," he added, "or they can be very dangerous."

Some also complain that these well-heeled prizes focus on established researchers who don't need lavish funding as much as peers in other, more obscure realms of science. They also don't give credit to the wide, collaborative networks of researchers whose collective efforts lead to breakthroughs as much as the work of lone geniuses. Criticism for lavishing so much money on a few researchers  rather than spreading the money more widely, and for downplaying collaboration is the main objection.

But the supporters say- these prizes inspire young people to follow in these scientists' footsteps. If they know recognition and large sums of money are within their grasp, even if it does take a big stroke of luck, they'll be more likely to start exploring those big questions themselves.

Mobile phones carry the personal microbiome of their owners

Most people on the planet own mobile phones, and these devices are increasingly being utilized to gather data relevant to our personal health, behavior, and environment. During an educational workshop, we investigated the utility of mobile phones to gather data about the personal microbiome — the collection of microorganisms associated with the personal effects of an individual. We characterized microbial communities on smartphone touchscreens to determine whether there was significant overlap with the skin microbiome sampled directly from their owners. We found that about 22% of the bacterial taxa on participants’ fingers were also present on their own phones, as compared to 17% they shared on average with other people’s phones. When considered as a group, bacterial communities on men’s phones were significantly different from those on their fingers, while women’s were not. Yet when considered on an individual level, men and women both shared significantly more of their bacterial communities with their own phones than with anyone else’s. In fact, 82% of the OTUs were shared between a person’s index and phone when considering the dominant taxa (OTUs with more than 0.1% of the sequences in an individual’s dataset). Our results suggest that mobile phones hold untapped potential as personal microbiome sensors.

Scientists have discovered the secrets behind electric fish, using genetic studies that revealed how these exotic creatures developed an organ that can unleash a wicked jolt.

Researchers on 26th June, 2014, unveiled a genetic blueprint of the electric eel - a fearsome denizen of South America that can zap you with an electric field of up to 600 volts - as well as detailed genetic data on two other types of electric fish.
Even though six groups of electric fish have evolved independently in far-flung locales like the muddy waters of the Amazon and murky marine environments, they all seem to have reached into the same "genetic toolbox" to fashion their electricity-generating organ, they said.

The new study found that various electric fish rely on the same genes and biological pathways to build their electric organs from skeletal muscle despite the different appearance and body location of their organs.

Their electrical abilities stand as one of the wonders of nature alongside traits like bioluminescence in some insects and sea creatures and echolocation in bats and whales.
"This only arose in fish because water is a conductor of electricity while air is not. Thus, birds or terrestrial animals could not come up with this''.
There are hundreds of species of electric fish worldwide, with varying degrees of electric power.

Fish with weak electric power use it to navigate in dim waters and communicate with one another. Those like the electric eel - a serpentine freshwater predator up to 8 feet long (2.4 meters) that is not a true eel but rather a catfish relative - possessing a powerful jolt use it to stun or kill prey and repel enemies.
"Electric organs start out their lives as muscle precursor cells. Through a series of developmental steps, they become larger, more electrically excitable and lose their ability to contract".
All muscle cells have electrical potential because any muscle contraction releases a small amount of voltage. Certain fish exploited that by transforming ordinary muscle cells into a larger type of cell called an electrocyte that generates vastly higher voltages. The electric organ is made of these cells.

"Each electric organ cell makes only a small voltage, similar in magnitude to our own muscles. The secret of electric organs is that the cells are aligned in stacks and electrically insulated so that the voltages add like batteries in a series," University of Texas neuroscience professor Harold Zakon said.

The six groups include: South American knife fishes, African electric catfish, African elephant fish, stargazers, some skates and some rays. Scientists think the electric organ first appeared in a fish 150 million to 200 million years ago.

The study was published in the journal Science.

Running cures blind mice

Exercise combined with visual stimulation helps to quickly restore vision in unused eye.
Sensory experience during locomotion promotes recovery of function in adult visual cortex.
Abstract

Recovery from sensory deprivation is slow and incomplete in adult visual cortex. In this study, we show that visual stimulation during locomotion, which increases the gain of visual responses in primary visual cortex, dramatically enhances recovery in the mouse. Excitatory neurons regained normal levels of response, while narrow-spiking (inhibitory) neurons remained less active. Visual stimulation or locomotion alone did not enhance recovery. Responses to the particular visual stimuli viewed by the animal during locomotion recovered, while those to another normally effective stimulus did not, suggesting that locomotion promotes the recovery only of the neural circuits that are activated concurrent with the locomotion. These findings may provide an avenue for improving recovery from amblyopia in humans.

Speed of light slower than thought, says US scientist
A US scientist claims to have found evidence that suggests that the speed of light as described by Einstein's theory of general relativity is slower than has been thought. The theory of general relativity suggests light travels at 299,792,458 metres/second in a vacuum.

The claim by physicist James Franson of the University of Maryland claims to have found evidence that suggests the speed of light is actually slower than has been thought. Franson's is based on observations made of the supernova SN 1987A, which exploded in 1987. Researchers on Earth picked up the arrival of both photons and neutrinos from the blast but The arrival of the photons was later than expected by 4.7 hours. Scientists at the time attributed it to a likelihood had said that this may be because the photons were from another source.

But what if that wasn't what it was, Franson has proposed that this may actually be because light slows down as it travels due to a property of photons known as vacuum polarization - where a photon splits into a positron and an electron for a very short time before recombining back into a photon. That should create a gravitational differential, Franson noted, between the pair of particles, which would have a tiny energy impact when they recombine - enough to cause a slight bit of a slowdown during travel.

Depression Makes Time Estimates More Accurate
Depressed people gauge time more accurately
When you are depressed, in which case your time-gauging abilities are pretty accurate reports PLOS ONE.
researchers in England and Ireland asked 39 students—18 with mild depression—to estimate the duration of tones lasting between two and 65 seconds and to produce tones of specified lengths of time.
Their results suggest that depressive realism, a phenomenon in which depressed people perceive themselves more accurately (and less positively) than typical individuals, may extend to aspects of thought beyond self-perception—in this case, time. They speculate that mindfulness treatments may be effective for depression, partly because they help depressed people focus on the moment, rather than its passing.

Controversial American scientist slammed for irresponsible flu research

Senior scientists have criticised an American university for allowing controversial research on enhancing a pandemic strain of flu virus to be undertaken in a laboratory with a relatively low level of biosecurity.
The University of Wisconsin-Madison was labelled irresponsible and negligent for allowing one of its scientists, Professor Yoshihiro Kawaoka, to genetically manipulate pandemic H1N1 flu virus in a laboratory categorised as biosafety level-2
Professor Kawaoka has for the past four years been working on ways of mutating the 2009 pandemic strain of H1N1 flu so that it is no longer neutralised by the antibodies that provide immunity for the wider population.
Biosafety level-1 (BSL-1)

For work on bacteria and viruses that do not generally cause disease in healthy adults. Precautions, such as washing hands with anti-bacterial soaps, are minimal and the work can be done on an open bench-top.

Biosafety level-2 (BSL-2)

For infectious agents with a moderate hazard to health or the environment, such as viruses or bacteria that cause mild disease in humans or are difficult to contract by airborne transmission. Gloves and gowns.

Biosafety level-3 (BSL-3)

This is for agents that can cause severe or fatal diseases in humans, such as plague, yellow fever and West Nile virus. Requires protective clothing and fume cupboards where the work is carried out.

Biosafety level-4 (BSL-4)

The highest level of safety for the most dangerous pathogens, such as Ebola, Marburg and Lassa viruses. Measures include high-security buildings, multiple showers, positive-pressure personnel suits and air filters.

Studies that claimed simple way to make stem cells withdrawn after 'extensive' errors found
The scientists who reported in January that they'd found a startlingly simple way to make stem cells have withdrawn that claim, following accusations of falsified data. On Wednesday, July 2, 2014, the journal Nature released a statement from the scientists who acknowledged "extensive" errors and said they couldn't say "without a doubt" that their method works.

Elastic Cloaking Material Makes Objects “Unfeelable”
Move over, invisibility cloaks. There's a structure that can keep objects from being felt or jostled
Scientists have developed an "unfeelability cloak," a material that hides objects within it from being felt or touched. The researchers suggest that in the future such cloaks might find help protect objects from bumps and pokes that might otherwise harm them.
Invisibility cloaks work by smoothly guiding light waves around objects so the waves ripple along their original trajectories as if nothing were there to block them. Scientists have designed cloaking materials that work against other kinds of waves as well—for example, inaudibility cloaks hide objects from the acoustic waves used in sonar.
The unfeelability cloak is a so-called pentamode metamaterial, an artificial structure that, despite being a solid, can behave like a fluid; although difficult to compress, its shape is otherwise easy to shift. The specific material the researchers devised is a three-dimensional hexagonal lattice reminiscent of a honeycomb, with the rods making up this lattice wider at their middles than at their ends.
The scientists built the cloak around the object they intended to hide, a rigid hollow cylinder that itself could hide anything big enough to fit within it. To simultaneously create both the cloak and the cylinder, the researchers shone an infrared laser beam into a vat of light-sensitive fluid, with plastic shapes hardening where the laser beam had focused. The resulting cloak was made of rods only about 40 microns long and 10 microns thick at their widest points, built around a cylinder 750 microns in diameter with walls 125 microns wide.

Tibetans live high life thanks to extinct human relatives
Modern people’s DNA adaptation to altitude passed down from ancient Denisovans
Tibetans inherited a genetic adaptation to high altitudes from an extinct group of human relatives called Denisovans, a new study finds.

Researchers have known for years that Tibetans carry a genetic variant in the EPAS1 gene that allows them to survive at extreme altitudes where oxygen is scarce. But how that variant arose has been mysterious. Now researchers report July 2 in Nature that the high-altitude version of EPAS1 almost certainly came from Denisovans or from a related group of extinct humans.

In the past, scientists concluded many of man’s defining qualities, such as legs made for walking upright and a large brain, evolved all at once. But according to a new study in the journal Science, shifts in climate caused these qualities to evolve separately.
''Evolution of early Homo: An integrated biological perspective ''
http://www.sciencemag.org/content/345/6192/1236828.abstract

Based on analyses of fossil evidence, the study researchers said the shrinking of forests and expansion of savannas in East Africa led to walking upright, which freed our forebears’ hands up for the creation and use of stone tools.

“Unstable climate conditions favored the evolution of the roots of human flexibility in our ancestors,” said study author Richard Potts, curator of anthropology and director of the Human Origins Program at the Smithsonian’s National Museum of Natural History. “The narrative of human evolution that arises from our analyses stresses the importance of adaptability to changing environments, rather than adaptation to any one environment, in the early success of the genus Homo.”

The study team found the predecessors of Homo erectus didn’t evolve in a series of progressively advanced iterations. Instead, a patchwork of at least three species lived alongside each other and the evolution of these species was driven by long-term climate factors in the region.

Scientists from Indian Institute of Science (IISc), Bangalore have developed a new non-invasive technique to identify dangerous and hazardous chemicals hidden inside any container including explosives.

This new technique, in addition, can also be used to as diagnostic tool for detection of tumors.

Prof Siva Umapathy from Inorganic and Physical Chemistry Department, IISc and his student Sanchita Sil, High Energy Materials Research Laboratory, Pune, said this new method can also be used for obtaining signals from samples which are concealed or packed inside containers such as commercial pastic bottles, thick papers, envelopes, coloured glass bottles etc.,

The novel technique is based on Raman spectroscopy--Universal Multile Angle Raman Sectroscopy (UMARS) and relies on illuminating the sample with the light source, which provides scattered light, offering molecular specific signatures to identify the chemical susstance, according to a research paper published in Nature Scientific Reports Journal dated June 16-2014.

Major Scientific Journal Joins Push to Screen Statistics in Papers It Publishes
Science's new policy follows efforts by other journals to bolster standards of data analysis
The journal Science is adding an extra round of statistical checks to its peer-review process, editor-in-chief Marcia McNutt announced on July 3. The policy follows similar efforts from other journals, after widespread concern that basic mistakes in data analysis are contributing to the irreproducibility of many published research findings. “As most journals are weak in statistical review, this damages the quality of what they publish. For the majority of scientific papers nowadays statistical review is more essential than expert review”. Most biomedical journals such as Annals of Internal Medicine, the Journal of the American Medical Association and The Lancet pay strong attention to statistical review.
Manuscript will be flagged up for additional scrutiny by the journal’s internal editors, or by its existing Board of Reviewing Editors (more than 100 scientists whom the journal regularly consults on papers) or by outside peer reviewers. The SBoRE panel will then find external statisticians to review these manuscripts.

Two new studies published in the journal Gastroenterology provide strong evidence that antiviral therapy can reduce the risk of liver cancer in patients with chronic hepatitis B infection.
Both papers support the accumulating evidence that, to avert the risk of liver cancer, antiviral therapy needs to be initiated early during the chronic hepatitis B infection, preferably before the stage of advanced fibrosis.

Undisclosed stocks of small pox virus can exist!
Do you think Smallpox, officially preserved in only two repositories worldwide ( Since its eradication in 1980, smallpox officially exists in only two places: the CDC in Atlanta, and its Russian counterpart, the State Research Center of Virology and Biotechnology VECTOR, in Novosibirsk), then think again. Because "variola”, the name of the virus that causes smallpox - may have been sitting alive and well in an unsecured US government refrigerator. On July 8, the US Centers for Disease Control and Prevention (CDC) announced that vials containing the deadly virus had been discovered in a cardboard box in the refrigerator, located on the National Institutes of Health (NIH) campus in Bethesda, Maryland. A similarly forgotten stock of smallpox was found in a lab in eastern Europe in the 1990s, for instance, and more recently at the Swiss Serum and Vaccine Institute in Bern.
Most experts believe that numerous stocks exist around the world, whether in clandestine labs or preserved in tissue, such as the scabs used for immunizations into the 20th century. They believe that the box now found that held the smallpox vials dates back to the 1950s, but the virus is extremely stable in its powdered form and could still be infectious.

A team of researchers in the U.S. and Germany has measured the highest level of ultraviolet radiation ever recorded on the Earth’s surface. The extraordinary UV fluxes, observed in the Bolivian Andes only 1,500 miles from the equator, are far above those normally considered to be harmful to both terrestrial and aquatic life. The results are being published in the open-access journal Frontiers in Environmental Science.
“A UV index of 11 is considered extreme, and has reached up to 26 in nearby locations in recent years,” notes Cabrol. “But on December 29, 2003, we measured an index of 43. If you’re at a beach in the U.S., you might experience an index of 8 or 9 during the summer, intense enough to warrant protection. You simply do not want to be outside when the index reaches 30 or 40.”

The intense radiation coincided with other circumstances that may have increased the UV flux, including ozone depletion by increased aerosols from both seasonal storms and fires in the area. In addition, a large solar flare occurred just two weeks before the highest UV fluxes were registered. Ultraviolet spikes continued to occur – albeit at lower intensity – throughout the period of solar instability, and stopped thereafter. While the evidence linking the solar event to the record-breaking radiation is only circumstantial, particles from such flares are known to affect atmospheric chemistry and may have increased ozone depletion.

High UV-B exposure negatively affects the entire biosphere, not just humans. It damages DNA, affects photosynthesis, and decreases the viability of eggs and larvae. For these reasons, it is important to keep a close watch on UV flux levels.

Although feelings are personal and subjective, the human brain turns them into a standard code that objectively represents emotions across different senses, situations and even people, reports a new study by Cornell University neuroscientist Adam Anderson. “We discovered that fine-grained patterns of neural activity within the orbitofrontal cortex, an area of the brain associated with emotional processing, act as a neural code which captures an individual’s subjective feeling,” says Anderson, associate professor of human development in Cornell’s College of Human Ecology and senior author of the study. “Population coding of affect across stimuli, modalities and individuals,” published online in Nature Neuroscience.

Two genes clear up psoriasis and eczema confusion
The two inflammatory skin disorders, often misdiagnosed, are distinguishable with a simple test
A test might prevent hundreds of thousands of misdiagnosed cases of skin disease by simply checking two genes, scientists report in the July 9 Science Translational Medicine.

Eczema and psoriasis are widespread, affecting 10 percent and 3 percent of the population, respectively. Both skin diseases produce itchy red patches that can look similar, even under the microscope. Accurate diagnosis is crucial because treatmentsfor one disease can exacerbate symptoms of the other.
Disease-specific genes could distinguish between the two, but so far scientists have searched in vain for such markers. The genes involved in each condition can differ between patients, so Eyerich and his colleagues compared tissue samples for eczema and psoriasis collected from 24 people afflicted with both disorders. After sequencing RNA from patients’ tissue samples, the team discovered 15 genes that could distinguish psoriasis from eczema.

The researchers screened the two best classifier genes, NOS2 and CCL27, among a second group of 34 patients, 16 with psoriasis and 18 with eczema. The researchers found that the two-gene test could discriminate between the disorders in every case.
