New research suggests sea level rise caused by man-made global warming is likely to increase the risk of devastating tsunamis. Scientists estimate that a minor rise of just 12 inches of sea level would put coastal communities in greater danger.
A new U.S. study examines whether quitting cigarettes is worth the weight gain, and finds you are still better off in the long run. Compared with smokers, even the quitters who gained the most weight had at least a 50 percent lower risk of dying prematurely from heart disease and other causes.
A new pesticide may be as harmful to bees as the old one. Chronic exposure to the sulfoximine-based insecticide sulfoxaflor produced significantly fewer workers than unexposed controls, and ultimately produced fewer reproductive offspring.
Cancer drugs may help the liver recover from common painkiller overdoses. Thousands of people overdose with Tylenol or other acetaminophen-containing drugs each year, leading to liver damage. In a new study, researchers found a way to repair the liver damage in mice.
A number of swirls (swirling patterns of magnetic polarizations called B-modes) recently detected in the faint echo of light at the edge of space could be signs of a previous universe existing before ours, according to a new study.
Stone Age mass graves unearthed on Scottish islands could have been used to house prehistoric tsunami victims, according to a controversial new study. The Orkney islands is home to at least 72 stone tombs – known as 'cairns' – dating back as far as 6,000 years ago.
The multicolored cloud bands that streak across Jupiter's face are roughly 1,900 miles deep (about 4% the planet's radius). And according to new research, they would be much deeper if Jupiter had a weaker magnetic field, which is currently 20,000 times stronger than Earth's.
“Facial feedback”, the idea that our facial expressions can feed back into our psychological state and behavior (for example, if your mouth is forced into a smile, you become a bit happier) has been supported by a new study, but if you feel like you’re being observed, this effect may be reduced.
In a new study examining peer pressure from robots, school-aged children tended to echo the incorrect but unanimous responses of a group of robots to a simple visual task, while adults who often go along with the errant judgments of human peers resisted such social pressure applied by robots.
In a breakthrough approach that combines virtual reality and artificial tactile sensations, two amputees feel as though their prosthetic hand belongs to their own body. Moreover, the scientists show that the phantom limb actually grows into the prosthetic hand.
A supermassive black hole has been discovered in a tiny galaxy: 'The galaxy, called Fornax UCD3, belongs to a recently discovered, rare and unusual class of stellar systems known as ultracompact dwarfs (UCDs), which are populated by older stars.'
Researchers find that isoniazid-resistant tuberculosis expressed diminished katG protein and switched from a glycotic metabolism to a fatty acid metabolism potentially exposing a new therapeutic target.
The North American Southwest was home to scarlet macaw breeding centers as early as 900 AD. Prized by the people of Chaco Canyon for their religious & cultural significance, macaws appear to have been raised in one of the first sustainable systems of non-agricultural animal husbandry in this region.
Researchers have found that children who need assistance improving their social skills might benefit more when grouped with peers who have similar social skill levels, rather than with peers who have a similar disability or disorder.
People with prediabetes who go to bed later, eat meals later and are more active and alert later in the day — those who have an “evening preference” — have higher body mass indices compared with people with prediabetes who do things earlier in the day, or exhibit morning preference.
A new HIV drug (ibalizumab) reduced viral replication and increased immune cells in individuals with advanced, drug-resistant HIV infection. Used in combination with existing HIV medications, the drug is a promising strategy for patients who have run out of effective treatment options.
Each insect olfactory system is tailored to a species' particular habitat and needs. And a new study suggests that this versatility is facilitated by the unique structure of odorant-gated ion channels.
How ugly marital spats might open the door to disease. “We think that this everyday marital distress – at least for some people – is causing changes in the gut that lead to inflammation and, potentially, illness.”
Men are better at navigating than women due to discrimination and unequal opportunities than any innate ability, according to a test conducted of more than 2.5 million people from every country in the world.
Researchers discover that the brains of bees and wasps can recognize faces. This is despite the tiny size of the insects' brains. They contain fewer than one million brain cells, compared with the 86 billion that make up a human brain.
Seabird species have responded to changing Arctic environmental conditions over the last four decades. Declines in the Black-legged Kittiwake are tied to deteriorating zooplankton productivity, while the Red-legged Kittiwakes, also declining, are more sensitive to warming ocean surface temperatures.
Scientists have just discovered scotoids, an entirely new geometric shape previously unknown to science or mathematics, and it's been hiding in your skin all along. As for why the scutoids exists at all, they say that the twisted prism enables a more energy-efficient shape as epithelial cells bend.
For the first time, scientists have shown that in certain people living with HIV, a type of antibody called immunoglobulin G3 (IgG3) stops the immune system's B cells from doing their normal job of fighting pathogens.
Although chemotherapies have been highly useful as targeted treatments for cancer, unwanted side effects still plague patients. Now, researchers have demonstrated that specialized nucleic acid-based nanostructures could be used to target cancer cells while bypassing normal cells.
