The asteroid that killed the dinosaurs also baked Earth for 100,000 years. By analyzing tiny fish bones and teeth, researchers determined global CO2 levels reached 2,300 ppm following the impact. For comparison, CO2 levels recently climbed above 410 ppm for the first time in millions of years.
The dominant hypothesis for why we evolved such large brains suggests that challenging social interactions were the driving force. A new study finds evidence against this idea and shows that human brain expansion was likely driven by ecology.
Scientists have discovered three vast canyons in one of the last places to be explored on Earth - under the ice at the South Pole. The deep troughs run for hundreds of kilometres, cutting through tall mountains - none of which are visible at the snowy surface of the continent.
Abortions don’t lead to an increased risk of suicidal thoughts - Suicidal ideation was similarly low for women who had abortions and for those denied abortions. Policies requiring that women be warned that they are at increased risk of becoming suicidal if they choose abortion are not evidence based
Researchers have found that oxytocin mediates subjective duration of social interactions. They found that socially less proficient individuals were less susceptible to the effect of "subjective time" than socially proficient ones. Social proficiency has been linked to one’s endogenous oxytocin level
Scientists have created a pill-size device that can detect bleeding deep inside a pig’s digestive tract and relay that information via a wireless signal to a cellphone. If modified to detect other chemicals this could be incredibly useful for human medical use.
Men take shortcuts, while women follow well-known routes, finds a new study that suggests that men and women tend to adopt different navigation strategies and men navigate more efficiently than women.
Quaillike creatures were the only birds to survive the dinosaur-killing asteroid impact. A new study suggests that widespread forest fires made it impossible for tree-dependent birds to survive, meaning the vast avian diversity of today likely arose from just a few ground-dwelling survivors.
Research highlights the psychological dangers of long-haul space flights particularly to Mars. Communication with family and friends will be extremely minimal. Even talking to Mission Control will be difficult, given that signals to and from the craft will take almost an hour to arrive.
UCLA scientists have identified specific gut bacteria that play an essential role in the anti-seizure effects of the high-fat, low-carbohydrate ketogenic diet. The study, published in the journal Cell, is the first to establish a causal link between seizure susceptibility and the gut microbiota.

Depression speeds up brain aging, find psychologists. This is the first study that provides comprehensive evidence for the effect of depression on decline in overall cognitive function (also referred to as cognitive state), in a general population.
Weekend sleep-ins may counteract the effects of lack of sleep during weekdays - Adults under the age of 65 who get 5 or fewer hours of sleep may have a higher risk of death compared to those who get 6 or 7 hours. However, individuals who then sleep longer on weekends had no raised mortality risk.
Danish DNA detective helps English police in homicide cases - A statistics researcher has helped English police identify likely perpetrators in a number of cases. Her unique method, now accepted in English case law, could lead to new legal standards.
By the end of this century, rice may not be what it used to be. As CO2 increases, rice loses B vitamins and other nutrients, which may put 600 million people at risk of nutritional deficiencies
Training compassion 'muscle' may boost brain's resilience to others' suffering. The findings may have implications for professions in which people routinely work with others who are suffering, like doctors, law enforcement officers and first responders.
High school students taught by a string of teachers who majored or minored in a specific teaching subject, instead of a general teaching degree, are more likely to become college graduates, finds analysis of more than 6,000 students and their teachers nationwide.
Stringent limits on global warming would bolster the world economy by averting tens of trillions of dollars in damage this century from heat waves, droughts and floods, a U.S. study said on Wednesday.
Laser-driven microbubble implosion is new way to create a tabletop particle accelerator. The technique uses high-energy laser pulses to irradiate tiny bubbles composed of hydrides. As the bubbles are squeezed together, high-energy hydrogen ions are released.
A study led by Harvard researchers finds that stretching reduced tumor growth by 52 percent in mice injected with breast cancer cells. Stretched mice showed signs of reduced inflammation and boosted immune cell activity.
An analysis of almost 295,000 people of all different weights may tie antidepressant use with weight gain. Researchers monitored health records for antidepressant use and weight gain over time, accounting for factors that may affect weight gain, like age, disease, smoking status and other drug use.
Leg exercise is critical to brain and nervous system health - Groundbreaking research shows that neurological health depends as much on signals sent by the body's large, leg muscles to the brain as it does on directives from the brain to the muscles.
Scientists at the University of Alberta have applied a machine learning technique using artificial intelligence to perfect and automate atomic-scale manufacturing, something which has never been done before. 'An atom-scale manufacturing revolution is sure to follow,' they say.
