WASHINGTON -- Researchers have developed a new device that can measure and control a nanoparticle trapped in a laser beam with unprecedented sensitivity. The new technology could help scientists study a macroscopic particle's motion with subatomic resolution, a scale governed by the rules of quantum mechanics rather than classical physics.
It's often said that the Arctic is one of the most vulnerable places to climate change. Temperatures are climbing faster there than anywhere else on the planet. Increasing winter temperatures mean increasing amounts of rain instead of snow, and scientists are still working to understand exactly what this means on the ground.
CAMBRIDGE, MA -- Researchers at MIT, Draper, and Brigham and Women's Hospital have designed an ingestible capsule that can be controlled using Bluetooth wireless technology. The capsule, which can be customized to deliver drugs, sense environmental conditions, or both, can reside in the stomach for at least a month, transmitting information and responding to instructions from a user's smartphone.
A new study published ahead-of-print by SLAS Discovery describes an evaluation of microplate-based high-throughput cellular thermal shift assay (CETSA HT) performed at AstraZeneca to assess its suitability and reliability for application to early drug discovery campaigns.

With fierce winds and flooding rains, hurricanes can be disasters for people -- and for ecosystems. These devastating storms have major effects on tropical forests, demolishing tree canopies and leaving behind debris that piles up in watershed streams and on forest floors.
Using laser light to trap atoms in a checkerboard-like pattern, a team led by Princeton scientists studied how resistance -- the loss of electrical current as heat -- can develop in unconventional metals.
The results may help explain how certain types of superconductors made from copper oxides are able to conduct electricity so efficiently. The research was published online Dec. 6 in the journal Science.
Your computer performs most tasks well. For word processing, certain computations, graphic arts and web surfing, the digital box on your desk is the best tool for the job. But the way your computer works, with its style of mathematics that relies on the binary code system of "on" and "off" 1s and 0s, isn't ideal for solving every problem.
Tight junctions are multi-protein complexes that serve as barriers in epithelial tissues such as the skin or lining of the gut. Loss of a specific tight junction barrier protein, claudin 18, occurs in the majority of gastric cancer patients and is correlated with poor prognosis in patients with advanced gastric cancer. Understanding how claudin 18 loss occurs and what pathways it regulates may provide new strategies to inhibit neoplastic progression in human gastric cancer patients.
OTTAWA - The Council of Canadian Academies (CCA) has released three reports on requests for medical assistance in dying (MAID), the result of an independent Expert Panel review conducted at the request of the federal government. The reports were released following their tabling in Parliament today.
Electronic prescribing is becoming widespread. All states allow it, some states require it, and many institutions now mandate electronic prescribing. Many electronic prescribing systems use computerized decision support algorithms that give automated warnings or alerts at the time of prescribing if a potential prescribing error is identified -- for example, regarding dosing or contraindications.
EVANSTON, Ill. --- Most people have heard about antibiotic-resistant germs. But how about antibiotic-resistant dust?
A new Northwestern University study has found that an antimicrobial chemical called triclosan is abundant in dust -- and linked to changes in its genetic makeup. The result is dust with organisms that could cause an antibiotic-resistant infection.
(Philadelphia, PA) - During an ischemic attack, the heart is temporarily robbed of its blood supply. The aftermath is devastating: reduced heart contractility, heart cell death, and heart failure. Contributing to these detrimental changes is a signaling molecule, G protein-coupled receptor kinase 2 (GRK2), which following ischemia accumulates in mitochondria, the energy-producing powerhouses of cells.
Research in recent years has linked a person's physical or social environment to their well-being. Stress wears down the body and compromises the immune system, leaving a person more vulnerable to illnesses and other conditions. Various stressors, from family adversity to air pollution, can lead to inflammation, diabetes and heart disease.
People with diabetes and followers of diets based on the glycemic index (GI) can enjoy dried fruits knowing they do not cause a blood sugar spike compared to starchy foods such as white bread, suggests a study published in the journal Nutrition and Diabetes.
The results of the study also suggest there's potential for food manufacturers to develop low GI foods with reformulations that include dried fruit, say Dr. John Sievenpiper of Toronto's St. Michael's Hospital and researcher Cyril Kendall of the hospital's Clinical Nutrition and Risk Factor Modi?cation Centre.
A simple online game can teach people to more accurately sort waste--with lasting results, a new UBC study has found.
Study participants who played the game developed by UBC researchers received immediate feedback on their sorting choices. The second time they played--when feedback was no longer provided--players still improved their average accuracy from 69 per cent to 84 per cent. Even when a week passed between games, players still improved their accuracy.
