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...

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-).
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.
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.
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.
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.
It's been a holiday decoration staple for decades, and it turns out that silver stuff hanging from your tree has quite a storied past. Tinsel has been made out of everything from real silver to lead.
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.
Colorado will spend more than $8 million researching marijuana's medical potential— a new frontier because government-funded marijuana research traditionally focuses on the drug's negative health effects.
A new study is challenging accepted ideas about how ancient soft-bodied organisms become part of the fossil record. Findings suggest that bacteria involved in the decay of those organisms play an active role in how fossils are formed— often in a matter of just a few tens to hundreds of years.
It’s that time of the year again. You probably think I mean Christmas, but as a virologist the sight of glitter, fairy lights and mounting pine trees immediately makes me think of the flu season. And if there’s one thing that can ruin your family’s Christmas, it’s the arrival of that unwanted guest. There are lots of myths around about flu. So, here’s a quick guide to some common knowledge that actually turns out to be wrong.
Smokers trying to quit often light up a cigarette to deal with stress. Now, an interdisciplinary team of researchers has shown that guanfacine, a medication approved for treating hypertension that reduces stress and enhances cognition, shows promise as a smoking cessation aid.
It's something your mother told you time and time again at the dinner table: "Eat your carrots, they'll help you see better!" So, was she right?
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.
Researchers have tested whether hugs act as a form of social support, protecting stressed people from getting sick. They found that greater social support and more frequent hugs protected people from the increased susceptibility to infection associated with being stressed and resulted in less severe illness symptoms.
The U.S. continues to look at the use and regulation of phthalates, which have been associated with health problems. Of particular concern is the safety of these plastic additives to children. When warmed by sunlight or a body’s heat, vinyl covers for crib mattresses release more phthalates.
Chemists have invented a powerful method for joining complex organic molecules that is extraordinarily robust and can be used to make pharmaceuticals, fabrics, dyes, plastics and other materials previously inaccessible to scientists.
In the biggest criminal case ever brought in the U.S. over contaminated medicine, 14 owners or employees of a Massachusetts pharmacy were charged today in connection with a 2012 meningitis outbreak that killed 64 people.
For some people, mistletoe might one day represent more than a kiss at Christmas time: it may mean better liver health. Researchers have found that a compound produced by a particular variety of the plant can help fight obesity-related liver disease in mice.
A team of scientists has mapped the location of hydrogen-rich waters found trapped kilometers beneath Earth's surface in rock fractures in Canada, South Africa and Scandinavia. Common in Precambrian Shield rocks— the oldest rocks on Earth— the ancient waters have a chemistry similar to that found near deep sea vents, suggesting these waters can support microbes living in isolation from the surface.
Don't want to be confronted with the number of calories in that margarita or craft beer? Then avoid the menu and order at the bar. New menu labeling rules from the FDA will require chain restaurants with 20 or more outlets to list the amount of calories in alcoholic drinks, along with other foods, on menus by next November.
Hypothesizing about the lab of the future in the next decade unveils specific technologies that will revolutionize the industry and propel science forward. In a recent Laboratory Equipment reader survey, 48 percent of respondents said instrumentation improvements will expand their research capabilities in the next 10 years.
The media is often accused of being perpetrators of bad news—that is, it takes every opportunity to report negative news. Take your local news channel, for example. I’d bet that on any given night, negative news reports outweigh positive reports by a ratio of 10:1. But, with the year coming to a close, I want to take time to highlight some of the positive strides society, specifically women in science, have made in 2014.
The challenge of purchasing equipment for a modern laboratory requires original, innovative thinking on several fronts. In today’s fast-changing work environment within the life sciences, it is crucial that the manager of a laboratory establish answers to several important questions, such as: What varieties of equipment are affordable? What specific equipment will be useful? And what should one specifically look for in an equipment seller?
