A Bronze Age palace excavation reveals an ancient wine cellar. Wine production, distribution, and consumption are thought to have played a role in the lives of those living in the Mediterranean and Near East during the Middle BronzeShow More Summary
Wolves may be susceptible to yawn contagion, according to a new study. Researchers suggest that contagious yawning may be linked to human capacity for empathy, but little evidence apart from studies on primates, exists that links contagious yawning to empathy in other animals. Show More Summary
An invasive grass species frequently found in forests has created a thriving habitat for wolf spiders, who then feed on American toads, a new study has found. Japanese stiltgrass, which was accidentally introduced to the US in the early 1900s, is one of the most pervasive invasive species. Show More Summary
By manipulating neural circuits in the brain of mice, scientists have altered the emotional associations of specific memories. The research reveals that the connections between the part of the brain that stores contextual information about an experience and the part of the brain that stores the emotional memory of that experience are malleable.
'Trending' topics on Twitter show the quantity of tweets associated with a specific event but trends only show the highest volume keywords and hashtags, and may not give information about the tweets themselves. Now, using data associated...Show More Summary
Big snowstorms will still occur in the Northern Hemisphere following global warming, a study shows. While most areas in the Northern Hemisphere will likely experience less snowfall throughout a season, the study concludes that extreme snow events will still occur, even in a future with significant warming.
Researchers analyzing human, fly, and worm genomes have found that these species have a number of key genomic processes in common, reflecting their shared ancestry. The findings offer insights into embryonic development, gene regulation and other biological processes vital to understanding human biology and disease.
Scientists have demonstrated a way to use a metallic complex, trinuclear titanium hydride, to accomplish the task of activating benzene by breaking the aromatic carbon-carbon bonds at relatively mild temperatures and in a highly selective way.
Most memories have some kind of emotion associated with them: Recalling the week you just spent at the beach probably makes you feel happy, while reflecting on being bullied provokes more negative feelings. A new study from neuroscientists reveals the brain circuit that controls how memories become linked with positive or negative emotions.
Using one of the most sensitive neutrino detectors on the planet, physicists have directly detected neutrinos created by the 'keystone' proton-proton fusion process going on at the sun's core for the first time.
Was Mars — now a cold, dry place — once a warm, wet planet that sustained life? Research underway may one day answer those questions — and perhaps even help pave the way for future colonization of the Red Planet. By analyzing the chemical...Show More Summary
The birth of massive galaxies, according to galaxy formation theories, begins with the buildup of a dense, compact core that is ablaze with the glow of millions of newly formed stars. Evidence of this early construction phase, however, has eluded astronomers — until now. Show More Summary
About 400 million years ago a group of fish began exploring land and evolved into tetrapods – today's amphibians, reptiles, birds, and mammals. But just how these ancient fish used their fishy bodies and fins in a terrestrial environment and what evolutionary processes were at play remain scientific mysteries.
Parents who try to understand their baby's babbling let their infants know they can communicate, which leads to children forming complex sounds and using language more quickly. The study's results showed infants whose mothers attended more closely to their babbling vocalized more complex sounds and develop language skills sooner.
The implications for cultural diversity and cultural competence in brain injury research and rehabilitation has been the focus of recent study. Risk for brain injury is higher among minorities, as is the likelihood for poorer outcomes. More research is needed to reduce health disparities and improve outcomes among minorities with brain injury, experts say.
Thirty percent of all positive hospital blood culture samples are discarded every day because they reflect the presence of skin germs instead of specific disease-causing bacteria. Now research demonstrates that rather than toss these...Show More Summary
Engineers and physicians have developed a smartphone application that checks for jaundice in newborns and can deliver results to parents and pediatricians within minutes. Skin that turns yellow can be a sure sign that a newborn is jaundiced and isn't adequately eliminating the chemical bilirubin. Show More Summary
While many scientists are trying to prevent the onset of a cancer defense mechanism known as autophagy, other researchers are leveraging it in a new therapy that causes the process to culminate in cell death rather than survival.
Thousands of fishing traps are lost or abandoned each year in US waters. A new NOAA report is the first of its kind to examine the derelict fish trap problem, nationally, and recommends actions to better manage and prevent it.
The Pacific tectonic plate is not as rigid as scientists believe, according to new calculations. Scientists have determined that cooling of the lithosphere -- the outermost layer of Earth -- makes some sections of the Pacific plate contract horizontally at faster rates than others and cause the plate to deform.
