Study Reveals Immune System is Dazed and Confused During Spaceflight
There is nothing like a head cold to make us feel a little dazed. We get things like colds and the flu because of changes in our immune system.
500 million year reset for the immune system
A single factor can reset the immune system of mice to a state likely similar to what it was 500 million years ago, when the first vertebrates emerged.
Why global warming is taking a break
Global warming is currently taking a break: whereas global temperatures rose drastically into the late 1990s, the global average temperature has risen only slightly since 1998 - surprising, considering scientific climate models predicted considerable warming due to rising greenhouse gas emissions.
Zombie ant fungi manipulate hosts to die on the 'doorstep' of the colony
A parasitic fungus that must kill its ant hosts outside their nest to reproduce and transmit their infection, manipulates its victims to die in the vicinity of the colony, ensuring a constant supply of potential new hosts, according to researchers at Penn State and colleagues at Brazil's Federal University of Vicosa.

The bacterium Clostridium difficile causes antibiotic-related diarrhoea and is a growing problem in the hospital environment and elsewhere in the community.
Exporting US coal to Asia could drop emissions 21 percent
Under the right scenario, exporting U.S. coal to power plants in South Korea could lead to a 21 percent drop in greenhouse gas emissions compared to burning the fossil fuel at plants in the United States, according to a new Duke University-led study.
No one-size-fits-all approach in a changing climate, changing land
As climate change alters habitats for birds and bees and everything in between, so too does the way humans decide to use land.

Turtles are well known for their longevity and protective shells, but it turns out these reptiles use sound to stick together and care for young, according to the Wildlife Conservation Society and other organizations.
Pygmy phenotype developed many times, adaptive to rainforest
The small body size associated with the pygmy phenotype is probably a selective adaptation for rainforest hunter-gatherers, according to an international team of researchers, but all African pygmy phenotypes do not have the same genetic underpinning, suggesting a more recent adaptation than previously thought.
Climate Change Will Threaten Fish by Drying Out Southwest U.S. Streams, Study Predicts
Fish species native to a major Arizona watershed may lose access to important segments of their habitat by 2050 as surface water flow is reduced by the effects of climate warming, new research suggests.

Trees and shrubs invading critical grasslands, diminish cattle production
Half of the Earth's land mass is made up of rangelands, which include grasslands and savannas, yet they are being transformed at an alarming rate.
Antibodies, together with viral 'inducers,' found to control HIV in mice
Although HIV can now be effectively suppressed using anti-retroviral drugs, it still comes surging back the moment the flow of drugs is stopped. Latent reservoirs of HIV-infected cells, invisible to the body's immune system and unreachable by pharmaceuticals, ensure that the infection will rebound after therapy is terminated.
Opioid users breathe easier with novel drug to treat respiratory depression
People taking prescription opioids to treat moderate to severe pain may be able to breathe a little easier, literally.
Innate lymphoid cells elicit T cell responses
In case of an inflammation the body releases substances that increase the immune defense. During chronic inflammation, this immune response gets out of control and can induce organ damage.
Old naked mole rats are young at heart, study finds
Cardiovascular disease is the greatest killer of humans the world over, presenting huge financial and quality-of-life issues.
Researchers obtain key insights into how the internal body clock is tuned
Researchers at UT Southwestern Medical Center have found a new way that internal body clocks are regulated by a type of molecule known as long non-coding RNA.
NOAA analysis reveals significant land cover changes in US coastal regions
A new NOAA nationwide analysis shows that between 1996 and 2011, 64,975 square miles in coastal regions--an area larger than the state of Wisconsin--experienced changes in land cover, including a decline in wetlands and forest cover with development a major contributing factor.
Purdue ag economists: Shale oil 'dividend' could pay for smaller carbon footprint
Unanticipated economic benefits from the shale oil and gas boom could help offset the costs of substantially reducing the U.S.'s carbon footprint, Purdue agricultural economists say.
Men fare worse than women in China regarding discrimination among obese workers
New research that analyzes economic disparity among obese Chinese adults shows that there is no wage disparity for obese women in China, but there is pay inequality among obese men.
More than just X and Y: A new genetic basis for sex determination
Men and women differ in plenty of obvious ways, and scientists have long known that genetic differences buried deep within our DNA underlie these distinctions.
Happiness in schizophrenia
Schizophrenia is among the most severe forms of mental illness, yet some people with the disease are as happy as those in good physical and mental health according to a study led by researchers at the University of California, San Diego School of Medicine.
Study at Deepwater Horizon spill site finds key to tracking pollutants
A new study of the ocean circulation patterns at the site of the Deepwater Horizon oil spill reveals the significant role small-scale ocean currents play in the spread of pollutants.
Flexible tapes from the nanoworld
Dr. Wilhelm Auwärter and his team are working on a research project to develop tiny flat molecule tapes at the Department of Physics of Technische Universität München (TUM).

Quasi-Legal Drug Fifteen Times Stronger Than Heroin Hides in Plain Sight
Emergency physicians should expect "an upswing in what on the surface appear to be heroin overdoses," but are actually overdoses tied to acetyl fentanyl, an opiate that is mixed into street drugs marketed as heroin.
Bionic Liquids from Lignin
While the powerful solvents known as ionic liquids show great promise for liberating fermentable sugars from lignocellulose and improving the economics of advanced biofuels, an even more promising candidate is on the horizon - bionic liquids.
New Tool Makes Online Personal Data More Transparent
The web can be an opaque black box: it leverages our personal information without our knowledge or control. When, for instance, a user sees an ad about depression online, she may not realize that she is seeing it because she recently sent an email about being sad.
Massachussetts General-developed device monitors key step in development of tumor metastases
A microfluidic device developed at Massachusetts General Hospital (MGH) may help study key steps in the process by which cancer cells break off from a primary tumor to invade other tissues and form metastases.
Do gut bacteria rule our minds?
It sounds like science fiction, but it seems that bacteria within us - which outnumber our own cells about 100-fold - may very well be affecting both our cravings and moods to get us to eat what they want, and often are driving us toward obesity.
Engineering long-lasting joint lubrication by mimicking nature
By finding a way to bind a slippery molecule naturally found in the fluid that surrounds healthy joints, Johns Hopkins researchers have engineered surfaces that have the potential to deliver long-lasting lubrication at specific spots throughout the body.
Rheumatologic diseases like lupus can initially look like neurological disorders
Lupus and other rheumatologic diseases can initially present as neurological disorders such as headaches and seizures, and thus delay diagnosis for many months, according to Loyola University Medical Center neurologists.
Personal, public costs of scientific misconduct calculated
Much has been assumed about the private and public damage of scientific misconduct. Yet few have tried to measure the costs to perpetrators and to society.
