Researchers at King's College London have discovered a vicious feedback loop underlying brain degeneration in Alzheimer's disease which may explain why so many drug trials have failed. The study also identifies a clinically approved drug which breaks the vicious cycle and protects against memory-loss in animal models of Alzheimer's.
WEST LAFAYETTE, Ind. -- Most of today's batteries are made up of rare lithium mined from the mountains of South America. If the world depletes this source, then battery production could stagnate.
Sodium is a very cheap and earth-abundant alternative to using lithium-ion batteries that is also known to turn purple and combust if exposed to water - even just water in the air.
New Rochelle, NY, September 19, 2018-- Recently, the U.S. National Institutes of Health (NIH) and Food and Drug Administration (FDA) called for the eliminating involvement of the Recombinant DNA Advisory Committee (RAC) in human gene therapy experiments, marking the end of an era of federal government oversight. While the RAC played an essential role in helping human gene therapy research evolve to where it is today, James M.
It's time to bring in laws to ban the sale of caffeinated energy drinks to children and young people in England to tackle the twin epidemics of obesity and mental health problems, argues Professor Russell Viner, President of the Royal College of Paediatrics and Child Health in The BMJ today.
Public Health England (PHE) has failed to learn the lessons over its partnership with the drinks industry, warn public health experts in The BMJ today.
Last week, Ian Gilmore, a senior government adviser on alcohol policy, stepped down from his role at PHE after the agency partnered with Drinkaware, an alcohol education charity that receives funding from industry, for a new campaign encouraging middle aged people to have more alcohol-free days per week.
New research suggests that there may be a link between higher levels of per- and polyfluoroalkyl substances (PFAS) in the environment and higher levels of hyperthyroidism in pet cats as they age. The findings are published in Environmental Toxicology and Chemistry.
Calcium carbonate is found nearly everywhere, in sidewalk cement, wall paint, antacid tablets and deep underground. Engineers at Washington University in St. Louis have used a unique set of state-of-the-art imaging techniques to discover how calcium carbonate nanoparticles nucleate, which is important for those manufacturing the carbonate nanomaterials and controlling metal carbonation during CO2 sequestration.
Scientists have long prized the roundworm Caenorhabditis elegans as a model for studying the biology of multicellular organisms. The millimeter-long worms are easy to grow in the lab and manipulate genetically, and have only around 1,000 cells, making them a powerful system for probing intricacies of development, behavior and metabolism.
Air pollution is now an established risk factor for heart disease/stroke and respiratory disease, but its potential role in neurodegenerative diseases, such as dementia, isn't clear.
To try and explore this further, the researchers used carefully calculated estimates of air and noise pollution levels across Greater London to assess potential links with new dementia diagnoses.
Artificial neural networks--algorithms inspired by connections in the brain--have "learned" to perform a variety of tasks, from pedestrian detection in self-driving cars, to analyzing medical images, to translating languages. Now, researchers at the University of California San Diego are training artificial neural networks to predict new stable materials.
The remains of a buried pine forest at the foot of Mont Saint Genis in Southern France yield insightful information on a drastic climate change event. The pine tree stand initiated around 12,900 years ago during the relatively warm "Allerød" period, and continued growing into the cold snap of the "Younger Dryas" period.
On Sunday, Sept. 16, Typhoon Mangkhut had made landfall in southern China and Hurricane signal #10 was still in force. NASA's Aqua satellite passed over the storm and captured an image that showed the storm after landfall.
A Red Alert, the most severe warning was issued by authorities in southern China.
At 5 a.m EDT (0900 UTC) on Sunday, Sept. 16, Mangkhut was centered near 21.6 north latitude and 113.6 east longitude, about 54 miles southwest of Hong Kong. Mangkhut was moving to the west-northwest at 17 knots and had maximum sustained winds 80 knots (92 mph/148 kph)
Careful sample preparation, electron tomography and quantitative analysis of 3D models provides unique insights into the inner structure of reverse osmosis membranes widely used for salt water desalination wastewater recycling and home use, according to a team of chemical engineers.
These reverse osmosis membranes are layers of material with an active aromatic polyamide layer that allows water molecules through, but screens out 99 to 99.9 percent of the salt.
ANN ARBOR, Mich. -- It's no secret that many teenagers stay up late to scroll through social media or catch up with friends on phones.
And 56 percent of parents of teens who have sleep troubles believe this use of electronics is hurting their child's shut-eye.
Students who witness violence in school at age 13 are at later risk of psycho-social and academic impairment at age 15, according to a new longitudinal study by researchers at Université de Montréal with colleagues in Belgium and France.
