Eggnog is a holiday treat, but it contains– surprise– eggs. So how come it’s okay for us to drink it? Here are a few questions and answers about eggnog and food safety.
An atomically thin material may lead to the thinnest-ever imaging platform. Synthetic two-dimensional materials based on metal chalcogenide compounds could be the basis for superthin devices, according to researchers.
Researchers have created a simple mathematical model based on optical measurements that explains the stunning colors of Yellowstone National Park's hot springs and can visually recreate how they appeared years ago, before decades of tourists contaminated the pools with make-a-wish coins and other detritus.
Researchers say they have collected promising weather data by flying instrument-laden drones into big Western and Midwestern storms. Now, they want to expand the project in hopes of learning more about how tornadoes form.
The Natural Resources Defense Council and the Environmental Defense Center have sued the Environmental Protection Agency (EPA) to strengthen standards to prevent pollution from stormwater, one of the nation’s most widespread forms of water pollution. More than a decade ago a federal appeals court ordered EPA to strengthen those protections, but the agency has failed to take action.
Here's a nice surprise: quantum physics is less complicated than we thought. An international team of researchers has proven that two peculiar features of the quantum world previously considered distinct are different manifestations of the same thing.
New research suggests that misfiring of the brain's control system might underpin compulsions in obsessive-compulsive disorder (OCD). The research is the latest in a series of studies investigating the possibility that compulsions in OCD are products of an overactive habit-system.
A study of more than 80,000 women has uncovered different risks of developing type 2 diabetes associated with different blood groups, with the biggest difference being a 35 percent increased risk of type 2 diabetes found in those with group B, Rhesus factor positive (R+) blood, compared with the universal donor group O, Rhesus factor negative (R-).
Impending fatherhood can lower two hormones— testosterone and estradiol— for men, even before their babies are born, according to a study. Other studies indicate that men's hormones change once they become fathers, and there is some evidence that this is a function of a decline after the child's birth. This is the first to show that the decline may begin even earlier, during the transition to fatherhood.
The Rosetta spacecraft caught up with the comet known as 67P/Churyumov-Gerasimenko beyond Mars this August, and its preliminary results— along with the studies it will allow in the near-future— top this year's list of the most important scientific breakthroughs, according to the editors of Science.
One factor that can raise a person’s risk of developing diabetes and other metabolic problems is chronic exposure to the stress hormone cortisol. Cortisol can counteract insulin, the hormone that regulates blood sugar, and slow the body’s production of it. As people in developing nations relocate from rural areas to cities, the increased stress is affecting their hormone levels and making them more susceptible to diabetes.
Researchers have identified a single protein as the root of painful and dangerous allergic reactions to a range of medications and other substances. If a new drug can be found that targets the problematic protein it could help smooth treatment for patients with conditions ranging from prostate cancer to diabetes to HIV.
Ibuprofen, a common over-the-counter drug worldwide, added to the healthy lifespan of yeast, worms and flies in a recent study. The treatment, given at doses comparable to the recommended human dose, added about 15 percent more to the species lives. In humans, that would be equivalent to another dozen or so years of healthy living.
A new study implicates a family of RNA-binding proteins in the regulation of cancer, particularly in a subtype of breast cancer. These proteins, known as Musashi proteins, can force cells into a state associated with increased proliferation.
Squid, what is it good for? You can eat it and you can make ink or dye from it, and now a team of researchers is using a protein complex that exists in the squid ring teeth to make a thermoplastic that can be used in 3-D printing.
Obesity can be a disability, the European Court of Justice ruled today— a decision that could have widespread consequences across the 28-nation bloc for the way in which employers deal with severely overweight staff. The ruling, which is binding across the EU, has such profound implications for employment law that experts expect EU nations to challenge it.
