Georgia Tech study finds that Instagram pictures with human faces are 38 percent more likely to receive likes than photos with no faces. They’re also 32 percent more likely to attract comments.
RNA encodes the proteins that play a key role in cellular reproduction, but the manner in which cells regulate its removal once these proteins are synthesized remains a mystery. One piece of this mystery has been solved as researchers at the University of North Carolina at Chapel Hill who have identified the steps by which a cell removes RNA from the cytoplasm.
The massive genome of the loblolly pine—around seven times bigger than the human genome—is the largest genome sequenced to date and the most complete conifer genome sequence ever published. This achievement marks the first big test of a new analysis method that can speed up genome assembly by compressing the raw sequence data 100-fold.
Scientists from Carnegie and Smithsonian museums and the University of Utah today unveiled the discovery, naming and description of a sharp-clawed, 500-pound, bird-like dinosaur that roamed the Dakotas with T. rex 66 million years ago and looked like an 11 ½-foot-long “chicken from hell.”
Why do we become saucer-eyed from fear and squint from disgust? These near-opposite facial expressions are rooted in emotional responses that exploit how our eyes gather and focus light to detect an unknown threat, according to a study by a Cornell University neuroscientist.
UC San Diego experiment is the first to show a connection between adult dishonesty and children’s behavior, with kids who have been lied to more likely to cheat and then to lie to cover up the transgression.
A powerful, new three-dimensional model provides fresh insight into the turbulent death throes of supernovas, whose final explosions outshine entire galaxies and populate the universe with elements that make life on Earth possible. Described in AIP Advances, it shows how the turbulent mixing of elements inside stars causes them to expand, contract, and spit out matter before they finally detonate.
The Institute for Research in Immunology and Cancer (IRIC) at the Université de Montréal (UdeM), in collaboration with the Maisonneuve-Rosemont Hospital’s Quebec Leukemia Cell Bank, recently achieved a significant breakthrough thanks to the laboratory growth of leukemic stem cells, which will speed up the development of new cancer drugs.
Researchers have analyzed 50 years’ worth of hit songs to identify key themes that marketing professionals can use to craft advertisements that will resonate with audiences.
One in eight visits to a a doctor for a headache or migraine end up with the patient going for a brain scan, at a total cost of about $1 billion a year, a new University of Michigan Medical School study finds. And many of those MRI and CT scans – and costs – are probably unnecessary, given the very low odds that serious issues lurk in the patients’ brains.
A new pre-clinical study by researchers at Temple University found that people who experience chronic sleep disturbance could face an earlier onset of dementia and Alzheimer’s.
We are less likely to humanize members of groups we don’t belong to—except, under some circumstances, when it comes to members of the opposite political party. A study by researchers at New York University and Harvard Business School suggests that we are more prone to view members of the opposite political party as human if we view those individuals as threatening.
A new study in Nature Geoscience shows that dust in the air in North Africa and West Asia absorbs sunlight west of India, warming the air and strengthening the winds carrying moisture eastward, raining down in India about a week later. The results explain one way that dust can affect the climate, filling in previously unknown details about the Earth system.
An international team of scientists has discovered that the last remaining stable portion of the Greenland ice sheet is stable no more. The finding will likely boost estimates of expected global sea level rise in the future.
While previous studies have suggested a connection between contagious yawning and empathy, new research from the Duke Center for Human Genome Variation finds that contagious yawning may decrease with age and is not strongly related to variables like empathy, tiredness and energy levels.
Research from the University of Adelaide has confirmed that a gene linked to intellectual disability is critical to the earliest stages of the development of human brains.
A brain-mapping study of patients with schizophrenia has found that areas associated with the ability to imitate are impaired, providing new support for the theory that deficits in this basic cognitive skill may underlie the profound difficulty with social interactions that characterize the disorder.

A University of Iowa researcher and colleague found greater diversity among insects in a rainforest in Peru than theory would predict.
A University of Wisconsin-Madison researcher has detected a higher rate of seizures among children with autism who were fed infant formula containing soy protein rather than milk protein. The study found excess seizures among girls and in the total sample of 1,949 children. The soy-seizure link reached borderline significance among boys, who comprised 87 percent of the children described in the database under study.
When it comes to Oscars and some other Hollywood movie awards, who your friends are affects whether you win, according to a new study.
A study led by UC San Diego shows that emotions can spread in an online social network -- and that positive emotion spreads more than negative.
An international team of scientists has discovered that the obesity-associated elements within FTO interact with IRX3, a distant gene on the genome that appears to be the functional obesity gene. The FTO gene itself appears to have only a peripheral effect on obesity. The study appears online March 12 in Nature.
A new fossil species, Cotylocara macei, shows evidence of echolocation and the complex anatomy underlying this unique behavior that has evolved in toothed whales, dolphins, and porpoises.
As the climate changes in the 21st century, more hurricanes may stray farther north along the eastern seaboard, like Superstorm Sandy did. During Sandy, researchers used crowdsourcing to collect the largest ever dataset of hurricane rain waters and analyze the storm's isotopic fingerprint.
Children who use their hands to gesture during a math lesson gain a deep understanding of the problems they are taught, according to new research from University of Chicago’s Department of Psychology.
How exactly does Twitter, with its 241 million users tweeting out 500 million messages daily, shape public opinion? That question was tackled by a group of researchers in China, who investigated how opinions evolve on Twitter by gathering about 6 million messages (tweeted over a six month period), which they ran through algorithms and analyzed. Described in the journal Chaos, the work reveals several surprises about how Twitter shapes public opinion, researchers say.
Innovative approach introduces five-to-eight year-olds to the concept of natural selection using a story book, and the children show remarkable comprehension
CHORI Scientists Rhonda Patrick, PhD and Bruce Ames, PhD, find causal link between Vitamin D, serotonin and autism. The findings point towards possible prevention and treatment options.
A team of astronomers from Canada and the United States used ALMA to study the often deadly relationship between highly luminous O-type stars and nearby protostars in the Orion Nebula. Their data reveal that protostars within 0.1 light-years (about 600 billion miles) of an O-type star are doomed to have their cocoons of dust and gas stripped away in just a few millions years, much faster than planets are able to form.
Kinases are proteins that play vital roles in disease, but scientists have struggled to study how they interact in real time. The lab of UNC's Klaus Hahn has developed a new technique to make these interactions occur and then watch them in real time to reveal some underlying causes of metastasis.
– By literally looking below the surface and digging up the dirt, Cornell researchers have discovered that a burgeoning deer population forever alters the progression of a forest’s natural future by creating environmental havoc in the soil and disrupting the soil’s natural seed banks.
Researchers have found that decision-making accuracy can be improved by postponing the onset of a decision by a mere fraction of a second. The results could further our understanding of neuropsychiatric conditions characterized by abnormalities in cognitive function and lead to new training strategies to improve decision-making in high-stake environments. The study was published in the March 5 online issue of the journal PLoS One.
Researchers at the University of California, San Diego School of Medicine have discovered that FDA-approved anti-psychotic drugs possess tumor-killing activity against the most aggressive form of primary brain cancer, glioblastoma.
Researchers have debated for more than two decades the likely impacts, if any, of global warming on the worldwide incidence of malaria, a mosquito-borne disease that infects more than 300 million people each year.
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have discovered the splattered remains of comets colliding together around a nearby star; the researchers believe they are witnessing the total destruction of one of these icy bodies once every five minutes.
Classroom programs designed to improve elementary school students’ social and emotional skills can also increase reading and math achievement, even if academic improvement is not a direct goal of the skills building, according to a study to be published this month in American Educational Research Journal (AERJ). The benefit holds true for students across a range of socio-economic backgrounds.
Georgia Tech has created a robotic drumming prosthesis with motors that power two drumsticks. The first stick is controlled both physically by the musicians’ arms and electronically using electromyography (EMG) muscle sensors. The other stick “listens” to the music being played and improvises.
Frequent Facebook users might be sharing more than party pictures, vacation videos and shameless selfies — they also share a greater risk of eating disorders, according to a new study led by Florida State University researchers.
Jeanette Wyneken, Ph.D., associate professor of biological science at Florida Atlantic University, and Kate Mansfield, Ph.D., a co-investigator at the University of Central Florida, are the first to successfully track neonate sea turtles in the Atlantic Ocean waters during what had previously been called their “lost years.” Findings from the study appear today in the journal Proceeding of the Royal Society B.
A new study found that neural circuits in the brain rapidly multitask between detecting and discriminating sensory input, such as headlights in the distance. That’s different from how electronic circuits work, where one circuit performs a very specific task. The brain, the study found, is wired in way that allows a single pathway to perform multiple tasks.
Researchers at New York University have identified the nature of brain activity that allows us to bridge time in our memories. Their findings offer new insights into the temporal nature of how we store our recollections and may offer a pathway for addressing memory-related afflictions.
Researchers analyzed fundraising and recruitment behavior among members of the Save Darfur Cause on Facebook. They found that the majority gave no money and recruited no one.
Astronomers at the University of Washington have developed a new method of gauging the atmospheric pressure of exoplanets, or worlds beyond the solar system, by looking for a certain type of molecule. And if there is life out in space, scientists may one day use this same technique to detect its biosignature — the telltale chemical signs of its presence — in the atmosphere of an alien world.
New research, titled “Lift and Wakes of Flying Snakes," appears March 4 in the journal Physics of Fluids. This work is the first to study the lift of a snake's cross-section computationally.
Animal flight behavior is an exciting frontier for engineers to both apply knowledge of aerodynamics and to learn from nature's solutions to operating in the air. Flying snakes are particularly intriguing to researchers because they lack wings or any other features that remotely resemble flight apparatus.
In the largest, most comprehensive, nationwide study to examine the prevalence of allergies from early childhood to old age, scientists from the National Institutes of Health report that allergy prevalence is the same across different regions of the United States, except in children 5 years and younger.
Looking to lose weight? Think happy thoughts. An international team of researchers has found that mood and food do more than just rhyme – your mood impacts what kind and how much food you eat.
The ruins of Sardis have been a rich source of knowledge about classical antiquity since the 7th century B.C., when the city was the capital of Lydia. Now, Sardis has given up another treasure in the form of two enigmatic ritual deposits, which are proving more difficult to fathom than the coins for which the city was famous.
