Lithium-ion batteries commonly used in consumer electronics are notorious for bursting into flame when damaged or improperly packaged. These incidents occasionally have grave consequences, including burns, house fires and at least one plane crash. Inspired by the weird behavior of some liquids that solidify on impact, researchers have developed a practical and inexpensive way to help prevent these fires.
A root canal ranks high on most people’s list of dreaded dental procedures. Although the lengthy and sometimes painful surgery relieves the agony of an infection, a root canal results in a dead tooth with no living soft tissue, or dental pulp, inside. Today, scientists report development of a peptide hydrogel designed to stimulate the growth of new blood vessels and dental pulp within a tooth after the procedure.
S&T recently demonstrated a new Federated Command and Control (FC2) infrastructure with the Florida Institute of Technology (FIT) that can protect a multitude of organizations at once—a federation—from potential threats using a variety of preventative measures and automated responses where malicious activity is detected, shared and mitigated.
New technique allows the spatiotemporal control of laser intensity, potentially changing the way laser-based accelerators are optimized.
The Endocrine Society has selected five new recipients for its Early Investigators Awards.
Soldiers on the battlefield or at remote bases often have to wait weeks for vital replacement parts. Now scientists report they have found a way to fabricate many of these parts within hours under combat conditions using water bottles, cardboard and other recyclable materials found on base as starting materials for 3D printing. They say this ‘game-changing’ advance could improve operational readiness, reduce dependence on outside supply chains and enhance safety.
In January, raging storms caused medical emergencies along the U.S. East Coast, prompting the Red Cross to issue an urgent call for blood donations. The nation’s blood supply was especially in need of O-type blood that can be universally administered in an emergency. Now, scientists say they have identified enzymes — from the human gut — that can turn type A and B blood into O, as much as 30 times more efficiently than previously studied enzymes.
Thousands of shipwrecks litter the seafloor all over the world, preserved in sediments and cold water. But when one of these ships is brought up from the depths, the wood quickly starts deteriorating. Today, scientists report a new way to use “smart” nanocomposites to conserve a 16th-century British warship, the Mary Rose, and its artifacts. The new approach could help preserve other salvaged ships by eliminating harmful acids without damaging the wooden structures themselves.
Once in the territory of science fiction, “nanobots” are closer than ever to becoming a reality, with possible applications in medicine, manufacturing, robotics and fluidics. Today, scientists report progress in developing the tiny machines: They have made nanobot pumps that destroy nerve agents, while simultaneously administering an antidote.
For thousands of years, people in the Middle East and South America have extracted water from the air to help sustain their populations. Drawing inspiration from those examples, researchers are now developing a lightweight, battery-powered freshwater harvester that could someday take as much as 10 gallons per hour from the air, even in arid locations. They say their nanofiber-based method could help address modern water shortages due to climate change, industrial pollution, droughts and groundwater depletion.
The Department of Homeland Security Science and Technology Directorate announced that DataRobot, Inc. of Tysons Corner, Virginia has received $200,000 to begin testing a prototype of a machine learning platform for the U.S. Customs and Border Protection’s Global Travel Assessment System.
If you can’t remember the last time you saw a teenager reading a book, newspaper or magazine, you’re not alone. In recent years, less than 20 percent of U.S. teens report reading a book, magazine or newspaper daily for pleasure, while more than 80 percent say they use social media every day, according to research published by the American Psychological Association.
Maple trees are best known for their maple syrup and lovely fall foliage. But it turns out that the beauty of those leaves could be skin-deep — and that’s a good thing. Today, scientists report that an extract from the leaves may prevent wrinkles.
Scientists report they have successfully developed and tested the world’s first ultrathin artificial retina that could vastly improve on existing implantable visualization technology for the blind. The flexible device, based on very thin 2D materials, could someday restore sight to the millions of people with retinal diseases. And with a few modifications, the device could be used to track heart and brain activity.
The popularity of electronic cigarettes continues to grow worldwide, as many people view them as a safer alternative to smoking. But the long-term effects of e-cigarette usage, commonly called “vaping,” are unknown. Today, researchers report that vaping may modify the genetic material, or DNA, in the oral cells of users, which could increase their cancer risk.
Nearly 700 million people suffer from mosquito-borne diseases — such as malaria, West Nile, Zika and dengue fever — each year, resulting in more than 1 million deaths. Increasingly, many species of mosquitoes have become resistant to the popular pyrethroid-based insecticides. Today, researchers report a new class of mosquito repellents based on naturally occurring compounds that are effective in repelling mosquitoes with potentially fewer environmental side effects than existing repellents.
About 50,000 people in the U.S. are diagnosed annually with head, neck, nasal and oral cancers. Most are treated with radiation, and of those, 70-80 percent develop a painful and debilitating side effect called severe oral mucositis (SOM).
Saliva is crucial for tasting and digesting food, but scientists have now found that it may have another, more subtle role. Salivary proteins could be part of a feedback loop that influences how food tastes to people — and by extension, what foods they’re willing to eat. The researchers hope that, one day, their findings could help consumers stick to a healthier diet.
America’s drug problem may be even worse than officials realize. And illicit drugs are consumed at a higher rate during celebratory events. Those are just two of the conclusions scientists have drawn from recent studies of drug residues in sewage.
Inflammatory bowel disease (IBD) is a set of painful conditions that can cause severe diarrhea and fatigue. Treatments can include medications and surgery. But now researchers report that a simple dietary intervention could mitigate colonic inflammation and improve gut health. In this case, a strawberry — or rather, less than a cupful of strawberries — a day could help keep the doctor away.
Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society (ACS), is today unveiling its annual “Talented 12” list. This award program, now in its fourth year, and for the first time sponsored by Thermo Fisher Scientific, recognizes young global stars in the chemical sciences that are working to solve some of the world’s most challenging problems. These up-and-coming innovators in chemistry will be debuted at an event today at ACS’ 256th National Meeting & Exposition. They are also featured in this week’s issue of C&EN.
Many people rely on contact lenses to improve their vision. But these sight-correcting devices don’t last forever — some are intended for a single day’s use — and they are eventually disposed of in various ways. Now, scientists are reporting that throwing these lenses down the drain at the end of their use could be contributing to microplastic pollution in waterways.
The life-threatening bacteria called MRSA can cripple a hospital since it spreads quickly and is resistant to treatment. But scientists report that they are now making advances in a new technique that avoids antibiotics. Instead, they are using light to activate oxygen, which then wipes out antibiotic-resistant bacteria. The method also could be used to treat other microbial infections, and possibly even cancer.
Georgetown Breast Cancer Advocates (GBCA), a volunteer group of survivors and other advocates who support and promote cancer research at Georgetown University, have published an article that underscores ways in which both the scientific and advocacy communities can foster a mutually beneficial collaboration.
Researchers from the George Washington University published an article in Trends in Parasitology outlining their lessons learned while creating vaccine candidates for hookworm and schistosomiasis.
