COVID-19 testing kits also can measure oral microbiome in saliva
COVID-19 saliva testing kits that include a novel preservative can also be used measure microscopic organisms in the mouth, a new study has found. This enables study of the relationship between mouth and lung microbes and the SARS-CoV-2 virus that ma.....»»
How well do wet masks contain droplets?
Researchers modeled what happens to respiratory droplets when they come in contact with wet masks. Their results show that damp masks are still effective at stopping these droplets from escaping the mask and being atomized into smaller, easier-to-spr.....»»
Twin study finds type 2 diabetes clues in epigenetic changes
Identical twins share the same DNA, but one twin can suffer from type 2 diabetes while the other twin does not develop the disease. Researchers have now discovered that there are differences in gene activity in twins where only one sibling had develo.....»»
Wearable device can detect and reverse opioid overdose
Researchers have developed a wearable device to detect and reverse an opioid overdose. The device, worn on the stomach like an insulin pump, senses when a person stops breathing and moving, and injects naloxone, a lifesaving antidote that can restore.....»»
New technique better assesses exposure of a population to a virus
Accurately assessing the exposure of a population to a particular virus is difficult because the tools for doing so do not account for the fact that many viruses comprise multiple circulating strains, or the fact that people can be vaccinated or natu.....»»
Exposure to harmless coronaviruses boosts SARS-CoV-2 immunity, study shows
Infections with the novel coronavirus and vaccination lead to strong antibody responses against SARS-CoV-2. Immune responses to other human coronaviruses, which mostly only cause harmless colds, also provide some protection against SARS-CoV-2. This c.....»»
Healthier UK diets linked to lower greenhouse gas emissions
A new analysis adds to evidence that nutritious diets are often more environmentally sustainable, while also demonstrating the feasibility of evaluating diet sustainability at the scale of specific foods -- rather than broader food-group categories......»»
Researchers shrink camera to the size of a salt grain
Researchers have developed an ultracompact camera the size of a coarse grain of salt. The new system can produce crisp, full-color images on par with a conventional compound camera lens 500,000 times larger in volume......»»
We might not know half of what’s in our cells, new AI technique reveals
Artificial intelligence-based technique reveals previously unknown cell components that may provide new clues to human development and disease......»»
Optoelectrode changes reduce injuries to brain tissue, improve nerve research
Researchers have developed a technique for assembling optoelectrodes that looks to offer the best of silicon-based electrodes and polymer-based electrodes. The scientists demonstrated it is possible to efficiently create a semiflexible light-emitting.....»»
Fighting blood diseases with artificial intelligence
How can we better diagnose blood diseases? A research group aims to answer this question with artificial intelligence (AI). Their goal is to facilitate the time-consuming analysis of bone marrow cells under the microscope. The researchers developed t.....»»
Poor sleep linked to feeling older and worse outlook on aging, which can impact health
Poor sleep in the over 50s is linked to more negative perceptions of aging, which in turn can impact physical, mental and cognitive health, new research has revealed. A study found that people who rated their sleep the worst also felt older, and perc.....»»
Cancer cells use ‘tiny tentacles’ to suppress the immune system
Investigators used the power of nanotechnology to discover a new way that cancer can disarm its would-be cellular attackers by extending out nanoscale tentacles that can reach into an immune cell and pull out its powerpack......»»
Giving social support to others may boost your health
When it comes to your health, being willing to give social support to your spouse, friends and family may be just as important as receiving assistance, a new study suggests......»»
Gold-based cancer therapy could face competition from other substances
The gold complex auranofin has traditionally been used for treating rheumatism but is also being evaluated as a treatment for certain forms of cancer. Researchers now show that other molecules that inhibit the same biological system have a more speci.....»»
Deleting dysfunctional cells alleviates diabetes
Eliminating old, dysfunctional cells in human fat also alleviates signs of diabetes, researchers report. The discovery could lead to new treatments for Type 2 diabetes and other metabolic diseases......»»
Only alcohol -- not caffeine, diet or lack of sleep -- might trigger heart rhythm condition
New research that tested possible triggers of a common heart condition, including caffeine, sleep deprivation and sleeping on the left side, found that only alcohol use was consistently associated with more episodes of the heart arrhythmia......»»
Morning exposure to deep red light improves declining eyesight
Just three minutes of exposure to deep red light once a week, when delivered in the morning, can significantly improve declining eyesight, finds a pioneering new study......»»
How eating less in early life could help with reproduction later on
New research shows how switching from a restricted diet to eating as much as you like could be beneficial for reproduction in later life. Researchers studied the eating and mating habits of the small fruit fly Drosophila melanogaster. They found that.....»»
Tracing mechanisms of large exon splicing during vertebrate evolution
In vertebrates, large exons often skip splicing events and are evolutionarily conserved. Scientists from Nagoya University, Japan, have recently identified the mechanism behind regulated splicing of large constitutive exons which are rich in disorder.....»»
