Physicists are working to bring the theory that parallel universes exist— called the multiverse hypothesis— firmly into the realm of testable science.
A space probe aiming to become the first to land on a comet has taken images that appear to show its target could actually be two separate lumps of rock and ice, scientists say.
Researchers have taken a broad look at changes in gene activity in response to diet in the Western honey bee. They found significant differences occur depending on what the bees eat.
A drug that is commonly used for arthritis has been shown to slow the progression of Alzheimer’s. A small randomized control study tested the drug Etanercept on patients with mild to moderate Alzheimer’s. Results showed that patients who were given Etanercept did not get any worse during the six month follow up compared to those on the placebo, who did decline.
A biochemist’s discovery of a class of anti-viral small molecules that target the function of a virus DNA hidden in the infected livers of hepatitis B patients may lead to a cure for this viral infection that kills more than 600,000 people annually.
Researchers have a better understanding of the asteroid Vesta and its internal structure, thanks to numerical simulations and data from the space mission Dawn. Their findings question contemporary models of rocky planet formation, including that of Earth.
In mice with diet-induced diabetes— the equivalent of type 2 diabetes in humans— a single injection of the protein FGF1 is enough to restore blood sugar levels to a healthy range for more than two days. The discovery could lead to a new generation of safer, more effective diabetes drugs.
Mathematical equations can make Internet communication via computer, mobile phone or satellite many times faster and more secure than today. Results from new software are attracting attention in the international technology media.
Genetics could be the key to explaining nations’ levels of happiness. Economists have looked at why certain countries top the world happiness rankings. They found that, the closer a nation is to the genetic makeup of Denmark, the happier that country is.
The same federal scientist who recently found forgotten samples of smallpox at a federal lab also uncovered more than 300 additional vials, many bearing the names of highly contagious viruses and bacteria such as dengue, influenza and rickettsia.
High body mass index is associated with multiple cardiovascular diseases. However, investigators have now confirmed that the risk of total mortality, cardiovascular mortality and myocardial infarction is highest among underweight patients, while cardiovascular mortality is lowest among overweight patients.
In the presence of charged substances, H2O molecules favor associating with elements with a negative electrical charge rather than a positive electric charge. Researchers have published a study on the subject that could provide new insights on the processes of cell formation.
New research indicates that arctic thermokarst lakes stabilize climate change by storing more greenhouse gases than they emit into the atmosphere. Countering a widely held view that thawing permafrost accelerates atmospheric warming, a study suggests that arctic thermokarst lakes are “net climate coolers” when observed over longer, millennial time scales.
Even mild traumatic brain injury may cause brain damage and thinking and memory problems, according to a study that found that, compared to people with no brain injury, those with injuries had brain damage in brain white matter.
Microsoft has announced the biggest layoffs in its history, saying it will cut up to 18,000 jobs or 14 percent of its staff as it works to cut down on management layers and integrate the Nokia cellphone business it bought in April.
