Ocean acidification (the ongoing decrease in the pH of the Earth's oceans, caused by the uptake of CO2 from the atmosphere), is affecting the formation of the skeleton of coralline algae which play an important part in marine biodiversity, new research from the University of Bristol, UK has found.
Agricultural policies aimed at alleviating poverty in Africa could be making things worse, according to research by the University of East Anglia (UEA).
BYU research shows unexpected immune system cells may help repair muscles.
An international team of scientists have discovered two new plankton-eating fossil fish species of the genus called Rhinconichthys from the oceans of the Cretaceous Period, about 92 million years ago, when dinosaurs roamed the planet.
New close-up images of the proteins that copy DNA inside the nucleus of a cell have led a team of scientists to propose a brand new mechanism for how this molecular machinery works. The scientists studied proteins from yeast cells, which share many features with the cells of complex organisms such as humans, and could offer new insight into ways that DNA replication can go awry.
Research published in 2012 garnered international attention by suggesting that a possible early human ancestor had lived on a diverse woodland diet including hard foods mixed in with tree bark, fruit, leaves and other plant products. But new research by an international team of researchers now shows that Australopithecus sediba didn’t have the jaw and tooth structure necessary to exist on a steady diet of hard foods.
By chance, scientists have discovered a malaria parasite that infects white-tailed deer. It’s the first-ever malaria parasite known to live in a deer species and the only native malaria parasite found in any mammal in North or South America.
Climate change may harm early-flowering plants not through plant-pollinator mismatch but through frost damage, a Dartmouth College-led study shows.
tars are born inside a rotating cloud of interstellar gas and dust, which contracts to stellar densities thanks to its own gravity. Before finding itself on the star, however, most of the cloud lands onto a circumstellar disk forming around the star owing to conservation of angular momentum.
Cellular senescence -- when a cell can no longer divide -- is a programmed stage in a cell's life cycle. Sometimes, as in aging, we wish it didn't happen so much and sometimes, as in cancer, we wish it would happen more. Given its important impacts on health, biologists wish they could explain more about what's happening in cells when senescence takes hold. A new study helps by showing that chromosomes become somewhat transformed, altering their patterns of gene expression.
Neurobiologists characterize nerve cells that detect motion by light changes.
If you just flubbed a big work project, you might be feeling down on yourself. Maybe you’ll head to the mall to indulge in a little retail therapy. Buying products is a common way to make yourself feel better, with half of all Americans reporting that they do it.
Sorry, Explorers Club, but woolly mammoth is no longer on the menu. Neither is the giant ground sloth.

For the first time ever, researchers from the University of Adelaide have been able to non-invasively study the inner workings of wombat warrens, with a little help from ground-penetrating radar.
HITS astrophysicists use new methods to simulate the common-envelope phase of binary stars, discovering dynamic irregularities that may help to explain how supernovae evolve.
Approximately 60,000 patients in the United States will receive a diagnosis of ductal carcinoma in situ (DCIS) in 2016. DCIS is not an invasive form of cancer and the 10-year survival rate for women with DCIS is greater than 98 percent. However, incidence of DCIS has increased dramatically over the last three decades, and being able to determine which women are among the small percentage at higher risk of breast cancer recurrence and mortality could help clinicians and patients tailor treatment to neither over treat nor under treat the disease.
Bursts of gamma rays from the center of our galaxy are not likely to be signals of dark matter but rather other astrophysical phenomena such as fast-rotating stars called millisecond pulsars, according to two new studies, one from a team based at Princeton University and the Massachusetts Institute of Technology and another based in the Netherlands.
Study of plaque production holds promise of helping improve treatment.
Researchers at the Stanford University School of Medicine have developed a fast, inexpensive and highly accurate test to screen newborns for cystic fibrosis. The new method detects virtually all mutations in the CF gene, preventing missed diagnoses that delay babies’ ability to begin receiving essential treatment.
Thousands flock to the internet in search of ways to boost a healthy lifestyle. Many popular diet facts and trends are circulated so often in the media that it’s hard to know which tips to trust and which ones should be tossed. Underneath popular opinion and platitudes, the truth about eating healthy may surprise you. A Texas A&M Health Science Center registered dietician separates myths from fact when it comes to your diet.
In 2010, a research team garnered attention when it published evidence of finding the first animals living in permanently anoxic conditions at the bottom of the sea. But a new study, led by scientists at the Woods Hole Oceanographic Institution (WHOI), raises doubts.
In Japan and areas like the Pacific Northwest where megathrust earthquakes are common, scientists may be able to better forecast large quakes based on periodic increases and decreases in the rate of slow, quiet slipping along the fault.
Until recently, being paralyzed from the waist down meant using a wheelchair to get around. And although daily life is more accessible to wheelchair users, they still face physical and social limitations. But UC Berkeley’s Robotics and Human Engineering Laboratory has been working to change that.
Loss of ice in Antarctica caused by a warming ocean could raise global sea levels by three metres, research suggests.
Study analyzes 40 years of science against 4 areas of sustainability.

Underrepresented students’ first-semester GPA may be a better predictor of whether they’ll graduate college than their ACT score or their family’s socioeconomic status, a new study found.
When it comes to making healthier food purchases in our nation’s grocery stores, the simpler the nutritional packaging is, the better. In fact, if one only has to look at a single number—a score that represents the nutritional value of what’s inside the packaging—a consumer is more likely to buy healthier products, finds a study involving research performed at the University of Pittsburgh.
New research published in Nature has shown how genome sequencing can be rapidly established to monitor outbreaks.
The effect of aging on cognitive processes such as learning, memory and logical reasoning have so far been studied almost exclusively in people. Using a series of touchscreen tests, Lisa Wallis and Friederike Range of the Messerli Research Institute at Vetmeduni Vienna have now studied these domains in pet dogs of varying ages.
Caltech biologists have modified a harmless virus in such a way that it can successfully enter the adult mouse brain through the bloodstream and deliver genes to cells of the nervous system. The virus could help researchers map the intricacies of the brain and holds promise for the delivery of novel therapeutics to address diseases such as Alzheimer's and Huntington's. In addition, the screening approach the researchers developed to identify the virus could be used to make additional vectors capable of targeting cells in other organs.

How has new legislation affected marijuana use in the United States? The best available data suggest that marijuana use is increasing in adults but not teens, with a decrease in marijuana-related arrests but an increase in treatment admissions, according to an update in the January/February Journal of Addiction Medicine, the official journal of the American Society of Addiction Medicine (ASAM). The journal is published by Wolters Kluwer.
A Drexel University materials scientist has discovered a way to grow a crystal ball in a lab. Not the kind that soothsayers use to predict the future, but a microscopic version that could be used to encapsulate medication in a way that would allow it to deliver its curative payload more effectively inside the body.
People who have self-reported penicillin allergy may have a three times greater chance of suffering from chronic hives. And people who have chronic hives tend to self-report penicillin allergy at a three times greater rate than the general population. Authors of a new study think it's not coincidence.
