| Why middle-class residents want to stay put after floodwaters recede Posted: 09 Aug 2021 11:41 AM PDT Flood disasters like Hurricane Harvey lead some people to move far from the places they had called home. But a new study finds that middle-class people who made long-term plans to stay in their neighborhoods before they flooded are less likely to relocate even if they suffered significant damage. |
| New study offers insight on how resistance training burns fat Posted: 09 Aug 2021 11:41 AM PDT Findings from a new study add to growing evidence that resistance exercise has unique benefits for fat loss. Researchers found that resistance-like exercise regulates fat cell metabolism at a molecular level. |
| New technology paves way towards personalized antibiotic therapy Posted: 09 Aug 2021 11:41 AM PDT Researchers have developed a method for monitoring bacterial responses to antibiotics in health-care settings that opens the door to personalized antibiotic therapy for patients. Using microwave sensing technology researchers have developed a low-cost, contactless, portable and reusable microwave sensor that acts as a fast and reliable evaluation tool for measuring antibiotic resistance. |
| Growing evidence of vitamin K benefits for heart health Posted: 09 Aug 2021 11:41 AM PDT New research has found that people who eat a diet rich in vitamin K have up to a 34 percent lower risk of atherosclerosis-related cardiovascular disease (conditions affecting the heart or blood vessels). |
| Posted: 09 Aug 2021 11:41 AM PDT Children's heavy digital media use is associated with a risk of being overweight later in adolescence. Physical activity protects children from the adverse effects of digital media on their weight later in adolescence. |
| Posted: 09 Aug 2021 11:40 AM PDT We all have an internal clock but what makes us tick? Scientists have developed new artificial intelligence (AI) and machine learning (ML) technology to understand how gene expression regulates an organism's circadian clock. |
| Brain connectivity can build better AI Posted: 09 Aug 2021 11:40 AM PDT By examining MRI data from a large Open Science repository, researchers reconstructed a brain connectivity pattern, and applied it to an artificial neural network (ANN). They trained the ANN to perform a cognitive memory task and observed how it worked to complete the assignment. These 'neuromorphic' neural networks were able to use the same underlying architecture to support a wide range of learning capacities across multiple contexts. |
| Microbes turn back the clock as research discovers their potential to reverse aging in the brain Posted: 09 Aug 2021 09:22 AM PDT Research introduces a novel approach to reverse aspects of aging-related deterioration in the brain and cognitive function via the microbes in the gut. |
| Innovative coating for blood vessels reduces rejection of transplanted organs Posted: 09 Aug 2021 08:28 AM PDT Researchers have found a way to reduce organ rejection following a transplant by using a special polymer to coat blood vessels on the organ to be transplanted. The polymer substantially diminished rejection of transplants in mice when tested. The discovery has the potential to eliminate the need for drugs -- typically with serious side effects -- on which transplant recipients rely to prevent their immune systems from attacking a new organ as a foreign object. |
| Bio-inspired, blood-repelling tissue glue could seal wounds quickly Posted: 09 Aug 2021 08:28 AM PDT Engineers have designed a strong, biocompatible glue that can seal injured tissues and stop bleeding, inspired by the sticky substance that barnacles use to cling to rocks. |
| Why people snub their friends with their phone Posted: 09 Aug 2021 07:59 AM PDT Smartphones have made multi-tasking easier, more understandable, and at times compulsive. But in social settings, these devices can lead to a form of contemporary rudeness called phone snubbing, or phubbing, the act of ignoring one's companions to pay attention to a phone. |
| New CRISPR/Cas9 technique corrects cystic fibrosis in cultured human stem cells Posted: 09 Aug 2021 07:59 AM PDT Researchers corrected mutations that cause cystic fibrosis in cultured human stem cells. They used a technique called prime editing to replace the 'faulty' piece of DNA with a healthy piece. The study shows that prime editing is safer than the conventional CRISPR/Cas9 technique. |
| Neurons that respond to touch are less picky than expected Posted: 09 Aug 2021 07:58 AM PDT Researchers used to believe that individual neurons were precisely tuned to respond to distinct types of touch. By studying rat whiskers, a team now finds that nearly all primary touch-sensitive neurons respond to an extensive range of motions and combination of motions and forces. |
| Study identifies molecule that stimulates muscle-building in humans Posted: 09 Aug 2021 07:05 AM PDT In a randomized control study of 10 healthy young men, researchers compared how consuming the single amino acid leucine or its two-molecule equivalent, dileucine, influenced muscle-building and breakdown. They found that dileucine boosts the metabolic processes that drive muscle growth 42% more than free leucine does. |
| Graphene binds drugs which kill bacteria on medical implants Posted: 09 Aug 2021 07:04 AM PDT Bacterial infections relating to medical implants place a huge burden on healthcare and cause great suffering to patients worldwide. Now, researchers have developed a new method to prevent such infections, by covering a graphene-based material with bactericidal molecules. |
| Starving pneumonia-causing bacteria of its favorite 'food' holds promise for new antibiotics Posted: 06 Aug 2021 12:58 PM PDT Researchers have revealed how the bacterium Streptococcus pneumoniae (pneumococcus) obtains the essential nutrient, manganese, from our bodies, which could lead to better therapies to target what is a life-threatening, antibiotic-resistant pathogen. |
