Soldiering in arctic conditions is tough. Protective clothing can be heavy and can cause overheating and sweating, while hands and feet can grow numb. To keep military personnel more comfortable, scientists are trying to create high-tech fabrics that heat up when powered and that capture sweat. These fabrics could conceivably be used in future consumer clothing.
Today, researchers report preliminary results suggesting that under simulated landfill conditions, quantum dots can leach out of TVs and tablets. But because this happens in such tiny amounts, the team says that in the grand scheme of things, it might make sense to use the more toxic quantum dots that are made with a more eco-friendly process. The researchers are presenting their results at the 254th National Meeting & Exposition of the American Chemical Society.
Scientists have tapped into the microbiome of elite runners and rowers, and have identified particular bacteria that may aid athletic performance. The goal is to develop probiotic supplements that may help athletes -- and even amateur fitness enthusiasts -- recover from a tough workout or more efficiently convert nutrients to energy. The researchers will present their work today at the 254th National Meeting & Exposition of the American Chemical Society.
From smart socks to workout clothes that measure exertion, wearable body sensors are becoming the latest 'must-have' technology. Now scientists report they are on the cusp of using silk, one of the world's most coveted fabrics, to develop a more sensitive and flexible generation of these multi-purpose devices that monitor a slew of body functions.
Whether to perform surgery on a fetus is a heart-wrenching decision. This type of surgery involves penetrating the delicate amniotic sac, increasing health risks to the fetus. Now researchers report the development of a glue, inspired by the tenacious grip of mussels on slippery rocks, that could one day help save the lives of the youngest patients.
While much of the research around the eclipse on Monday will focus on the effects of the Sun's brief, daytime disappearance on Earth and its atmosphere, a group of solar physicists will be leveraging the rare event to capture a better glimpse of the star itself.
Thanks to a secret vaccine ingredient as well as a net of worldwide researchers and successful vaccination campaigns, smallpox was finally eradicated in 1977. A new study provides an in-depth investigation of the mysteries associated with the development of smallpox vaccine and is a rich and interesting account of how the vaccine lymph was spread worldwide.
A new approach to optical imaging makes it possible to quickly and economically monitor multiple molecular interactions in a large area of living tissue -- such as an organ or a small animal; technology that could have applications in medical diagnosis, guided surgery, or pre-clinical drug testing.
A new preclinical study found that a brief period of extended wakefulness before surgery enhances pain and prolongs recovery time after surgery. Caffeine administration helped to reduce the harmful effects of sleep loss on subsequent surgical pain.
Astrophysicists have discovered two detached, eclipsing double white dwarf binaries with orbital periods of 40 and 46 minutes, respectively. White dwarfs are the remnants of Sun-like stars, many of which are found in pairs, or binaries.
Brazilian free-tailed bats are expert flyers, capable of migrating hundreds of miles and regularly traveling more than 30 miles a night. But they pull up short at a narrow ocean channel that cuts across the Bahamas, dividing bat populations that last shared an ancestor hundreds of thousands of years ago.
A team of Israel Antiquities Authority (IAA) archaeologists and students has discovered an Assyrian-period water system near Rosh Ha-Ayin, a city in the Central District of Israel. “It is difficult not to be impressed by the sight of the immense underground reservoir quarried out so many years ago,” said Dr. Gilad Itach, director of excavations [...]
Ever more people are suffering from cardiac insufficiency. The main cause of reduced cardiac functionality lies in the irreversible loss of cardiac muscle cells due to disease, especially ischemic diseases such as cardiac infarction. There is still no treatment to reverse damage of this nature. Research is ongoing to develop methods of repairing such damage to normalize cardiac function. A promising approach: cardiac muscle tissue made of spider silk.
Every tissue has its own pattern of active alleles, a large-scale study has found. Researchers were able to show that the differential allele activity is regulated by tissue-specific, regulatory DNA elements known as enhancers - a process that could also be involved in many diseases.
