The Food and Drug Administration on Friday revised sweeping food safety rules proposed last year after farmers complained that the regulations could hurt business.
By comparing nine ancient genomes to those of modern humans, scientists have shown that previously unrecognized groups contributed to the genetic mix now present in most modern-day Europeans.
On this episode of Bioscience Technology This Week, Christina Jakubowski explores the role that bees may play in the search for antibiotic alternatives. Our second story focuses on how increased carbon dioxide levels in water can rob sharks of their ability to sense the smell of food.
Earth's protective ozone layer is beginning to recover, largely because of the phase-out since the 1980s of certain chemicals used in refrigerants and aerosol cans, a U.N. scientific panel reported Wednesday.
Life can be so intricate and novel that even a single cell can pack a few surprises, according to a new study. The pond-dwelling, single-celled organism Oxytricha trifallax has the remarkable ability to break its own DNA into nearly a quarter-million pieces and rapidly reassemble those pieces when it's time to mate, the study says.
Smoking is banned in more than eight out of 10 U.S. homes— nearly twice as many as two decades ago, according to a new government study. The Centers for Disease Control and Prevention found smoking is even forbidden in nearly half of homes where an adult smoker resides.
An unusual new fossil discovery of one of the earliest animals on earth may also provide the oldest evidence of muscle tissue– the bundles of cells that make movement in animals possible.
At first blush it is a bit disingenuous, using beer waste as a base material for new bone. But that is exactly what a multidisciplinary team of researchers in Spain has come up with in a process for making the substrate material on which bone can be regenerated.
A researcher believes that the potential human health implications of bee colony collapse disorder extend beyond the drop in pollination to the impact on humans of long exposure to low-level poisons, like neonicotinoid pesticides.
A study of 1,400 ancient and modern human skulls suggests that a reduction in testosterone hormone levels accompanied the development of cooperation, complex communication and modern culture some 50,000 years ago.
A water ban that had hundreds of thousands of people in Ohio and Michigan scrambling for drinking water has been lifted, Toledo's mayor announced Monday.
On this episode of Bioscience Technology This Week, Editor-in-Chief Rob Fee reports on gold nanoparticles' promise in drug delivery. Our second story examines the work being done to decipher the wheat genome and the implications of this work.
Stop sunbathing and using indoor tanning beds, the acting U.S. surgeon general warned in a report released Tuesday that cites an alarming 200 percent jump in deadly melanoma cases since 1973.
A new study has found that turning the thermostat down a few notches at night may expand brown fat tissue mass and activity, which could lead to metabolic benefits such as more effective disposal of glucose.
A cross-disciplinary team is calling for public discussion about a potential new way to solve longstanding global ecological problems by using an emerging technology called “gene drives.” The advance could potentially lead to powerful new ways of combating malaria and other insect-borne diseases.
As daily temperatures increase, so does the number of patients seeking treatment for kidney stones. In a study that may both reflect and foretell a warming planet’s impact on human health, a research team found a link between hot days and kidney stones in 60,000 patients in several U.S. cities with varying climates.
Bowel cancer patients with high levels of vitamin D in their blood are more likely to survive the disease, a new study shows. Patients with the highest levels of vitamin D have half the risk of dying compared with those with the lowest levels, the findings reveal.
Re-examination of a circa 100,000-year-old archaic early human skull found 35 years ago in Northern China has revealed the surprising presence of an inner-ear formation long thought to occur only in Neandertals.
Mice exposed to low doses of arsenic in drinking water, similar to what some people might consume, developed lung cancer, researchers have found. Arsenic is present in the environment as a naturally occurring substance or due to contamination from human activity.
The elaborate courtship dance done by flies combines multiple motor skills with advanced sensory cues. Remarkably, this behavior is entirely innate. Now, researchers have determined that the Abdominal-B (Abd-B) gene is important for this complex behavior.
Emotional and behavioral problems show up even with low exposure to lead, and as blood lead levels increase in children, so do the problems, according to new research.
Environmental policy must respond to ever-changing conditions on the ground and in the water, but doing so requires a constant flow of information about the living world. Now, scientists propose employing emerging environmental DNA sampling techniques that could make assessing the biodiversity of marine ecosystems as easy as taking a water sample.
Figuring out how to survive on a lean-season diet of hard-to-reach ants, slugs and other bugs may have spurred the development of bigger brains and higher-level cognitive functions in the ancestors of humans and other primates, suggests new research.
A new study being presented at ICE/ENDO 2014, the joint meeting of the International Society of Endocrinology and the Endocrine Society in Chicago, demonstrates that ambient temperatures can influence the growth or loss of brown fat in people. Cool environments stimulate growth, warm environments loss.
Ruminant livestock are the single largest source of methane emissions, and in a country like New Zealand, where the sheep outnumber people 7 to 1, that’s a big deal. However, not all ruminants are equal when it comes to greenhouse gas emissions. It turns out that the amount of methane produced varies substantially across individual animals of the same ruminant species.
