Researchers say they have identified a previously unknown gene and associated protein (which they have named 'aggregatin') which could potentially be suppressed to slow the advance of Alzheimer's disease.
Engineers build full lithium-ion batteries with silicon anodes and an alumina layer to protect cathodes from degrading. By limiting their energy density, the batteries promise excellent stability for transportation and grid storage use.
Increased uptake of plant-based diets in New Zealand could substantially reduce greenhouse gas emissions while greatly improving population health and saving the healthcare system billions of dollars in the coming decades, according to a new study.
The planarian flatworm is a simple animal with a mighty ability: it can regenerate itself from nearly every imaginable injury, including decapitation. Scientists have studied these worms for decades to better understand fundamental principles of natural regeneration and repair. One mechanism that is yet unknown is how organisms like these control the proportional scaling of tissue during regeneration. Now, molecular biologists have identified the beginnings of a genetic signaling pathway that puts the brakes on the animal's tissue growth.
Hydrologists diving off the coast of the Philippines have discovered volcanic seeps with some of the highest natural levels of C02 ever recorded. The scientists were working in Verde Island Passage, one of the most diverse marine ecosystems in the world and is home to thriving coral reefs.
Researchers have proposed a system that would use currently underutilized resources in an existing wireless channel to create extra opportunities for lag-free connections. The process, which wouldn't require any additional hardware or wireless spectrum resources, could alleviate traffic backups on networks with many wireless connections, such as those found in smart warehouses and automated factories.
Scientists have uncovered a broad diversity of large and giant viruses that belong to the nucleocytoplasmic large DNA viruses (NCLDV) supergroup. As a result, virus diversity in this group expanded 10-fold from just 205 genomes, redefining the phylogenetic tree of giant viruses.
New research reveals the impact of smell loss. As many as one in 20 people live without smell. But until now there has been little research into the range of emotional and practical impacts it causes. The new study finds that almost every aspect of life is disrupted - from everyday concerns about personal hygiene to a loss of sexual intimacy and the break-down of personal relationships.
For decades, there's been a widespread assumption among people with an interest in sports-related injury that youth football players are more vulnerable to concussion and other head injuries than their older, bigger counterparts.
Many drugs are derived from natural products. But before natural products can be exploited, chemists must first determine their structure and stereochemistry. This can be a major challenge, particularly when the molecules cannot be crystallized and contain only few hydrogen atoms. A new NMR-based method now simplifies the analysis and produces more accurate results.
Cross-linked polymers are structures where large molecular chains are linked together, allowing exceptional mechanical properties and chemical resistance to the final product. However, their modification is not easy. Now, scientists develop a method that allows the fusion of different polymers together easily, allowing the precise tuning of the properties of the final material by selecting appropriate base polymers and mixing them at the right proportion.
Animal pollinators support the production of three-quarters of the world's food crops, and many flowers produce nectar to reward the pollinators. A new study using bumblebees has found that the sweetest nectar is not necessarily the best: too much sugar slows down the bees. The results will inform breeding efforts to make crops more attractive to pollinators, boosting yields to feed our growing global population.
