A three-part study suggests that the deep voices of primates, including humans, evolved to intimidate rival males, not as a tactic to attract potential mates.
Finding the vulnerable points where HIV enters the female reproductive tract is like searching for needles in a haystack. But scientists have solved that challenge by creating a glowing map of the very first cells to be infected with a HIV-like virus.
Tooth-marks on a 500,000-year-old hominin femur bone found in a Moroccan cave indicate that it was consumed by large carnivores, likely hyenas.
Modern horses are expert runners. They reach top speeds using a special running gait in which they hold their back stiff as they move. A new study reveals that tiny fossil ancestors of modern horses may have moved quite differently.
Researchers have found that a single minute of very intense exercise produces health benefits similar to longer, traditional endurance training. The findings put to rest the common excuse of "there is not enough time."
Chocolate is divinely delicious, mouthwateringly smooth and unfortunately full of fat. But reducing the fat content of the confection makes it harder and less likely to melt in your mouth.
Why does one person who tries cocaine get addicted, while another might use it and then leave it alone? Why do some people who kick a drug habit manage to stay clean, while others relapse?
Scientists are teaching computers to figure out why people accept or decline invitations to participate in clinical trials. Recruiting sufficient numbers of participants is a current challenge in medical research that can compromise results.
While norovirus is often linked in the news to outbreaks on cruise ships, the highly contagious stomach bug sickens nearly 700 million around the world every year and results in roughly $4.2 billion in health care costs and $60.3 billion in societal costs annually.
Targeting cancer cells for destruction while leaving healthy cells alone—that has been the promise of the emerging field of cancer nanomedicine. But a new meta-analysis indicates that progress so far has been limited.
Meticulous records kept by Shinto priests and Finnish fisherman show a warming world over a number of centuries, according to a new study. The “citizen scientists” marked the dates when lakes and rivers would freeze in the winter, then break up again for spring.
The Hubble Space Telescope has detected a tiny, dark moon circling the dwarf planet on the frozen fringes of our solar system. Scientists announced the discovery by some members of the team that spotted Pluto's smaller moons years ago.
The EVOLVE manual pipette range from INTEGRA features three adjustable dials for setting each individual volume digit.
Scientists have discovered Sarmientosaurus musacchioi, a new species of titanosaurian dinosaur, based on a complete skull and partial neck fossil unearthed in Patagonia, Argentina.
CSIRO, one of Australia’s most prestigious science organizations, is reportedly reconsidering its decision to cut much of climate science staffing – just in time for the Australian Senate’s inquiry to widen this week.
