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...
A researcher believes that the potential human health implications of bee colony collapse...
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.
An imbalance of female sex hormones among men in Western nations may be contributing to high levels of male obesity, according to new research. The study suggest that obesity among Western men could be linked with exposure to substances containing the female sex hormone estrogen.
Infants exposed to rodent and pet dander, roach allergens and a wide variety of household bacteria in the first year of life appear less likely to suffer from allergies, wheezing and asthma, according to a new study.
A new study shows how exposure to air pollution early in life produces harmful changes in the brains of mice, including an enlargement of part of the brain that is seen in humans who have autism and schizophrenia.
Young men who use cannabis may be putting their fertility at risk by inadvertently affecting the size and shape of their sperm, according to recently published research.
As humans, how, and why, do we think and act so differently from other species? A new study suggests that the big difference between humans and other species may lie in how we use our brains for routine tasks.
The intimate interaction between a plant and its environment has sent some puzzling cues to scientists trying to determine how, at the molecular level, a plant becomes infected by bacteria. At this level, researchers have found that plants sometimes beckon the bacteria in a seemingly counterintuitive action to its health.
A newly developed fuel-cell concept will allow biodiesel plants to eliminate the creation of hazardous wastes while removing their dependence on fossil fuel from their production process.
Scientists have discovered that the earliest living organisms on Earth were capable of making a mineral that may be found on Mars. The clay-mineral stevensite has been used since ancient times, but scientists had believed deposits could only be formed in harsh conditions. Researchers found living microbes create an environment that allows stevensite to form, raising new questions about the stevensite found on Mars.
A new study uses genetic information extracted from the remains of an adolescent girl to help resolve the longstanding debate about the origins of the first people to inhabit the Americas.
A new study of preschools and day care centers finds that flame retardants are prevalent indoors, potentially exposing young children to chemicals known to be hazardous.
