Thursday September 16th, 2021 09:34:48 PM
A family of fishes, called the cichlids, in Africa's Lake Malawi is helping researchers refine our understanding of how evolution works.

'Blue food revolution' to tackle climate change and malnutrition

Thursday September 16th, 2021 09:34:40 PM
An unprecedented review of the aquatic foods sector has uncovered how fisheries and aquaculture can play a greater role in delivering healthy diets and more sustainable, equitable and resilient food systems around the world.

Patients with multiple sclerosis show robust T-cell responses to mRNA COVID-19 vaccines

Thursday September 16th, 2021 09:34:34 PM
New research shows that mRNA COVID-19 vaccines are effective at inducing T-cell responses in multiple sclerosis patients who receive B cell-depleting infusions even if their antibody responses are diminished.

COVID-19 virus is evolving to get better at becoming airborne, new study shows

Thursday September 16th, 2021 09:34:28 PM
A new study finds that SARS-CoV-2 is evolving toward more efficient aerosol generation, and loose-fitting masks provide significant but only modest source control. Until vaccination rates are very high, continued layered controls, including improved ventilation, increased filtration, UV air sanitation, and tight-fitting masks are critical to protect people in public-facing jobs and indoor spaces, researchers urge.

Consuming fruit and vegetables and exercising can make you happier

Thursday September 16th, 2021 06:29:36 PM
New research led by the University of Kent and University of Reading has found that fruit and vegetable consumption and exercise can increase levels of happiness.

Low oxygen levels are pushing fish into shallower waters, with potentially devastating impacts for fisheries and ecosystems

Thursday September 16th, 2021 06:29:21 PM
Fish can drown. While it may not seem like it, fish do require oxygen to breathe; it's just that they get what they need from the oxygen dissolved in water rather than in the air. Too little oxygen spells trouble for our finned friends, which have to move or else suffer ill effects.

Studies biased toward genomes of people with European ancestry still predict cancer risk in diverse groups, research finds

Thursday September 16th, 2021 06:29:13 PM
Data sets that are biased by having too many genomes from people with European ancestry can still be applied to other ancestry groups to predict their risk of developing breast and prostate cancer, researchers report.

Link between inflammation and pancreatic cancer development uncovered

Thursday September 16th, 2021 06:29:02 PM
A new study finds that pancreatic cells display an adaptive response to repeated inflammation that initially protects against tissue damage but can promote tumor formation in the presence of mutant KRAS.

Cancer cells’ unexpected genetic tricks for evading the immune system

Thursday September 16th, 2021 06:28:56 PM
In a surprising new finding in mice, researchers have discovered that many genes linked to human cancer block the body's natural defense against malignancies.

Friend or foe? Researchers investigate the mysterious microbes living inside corals

Thursday September 16th, 2021 06:28:53 PM
In a new article, researchers describe investigations into an enigmatic group of coral-infecting microbes.

Researchers infuse bacteria with silver to improve power efficiency in fuel cells

Thursday September 16th, 2021 06:28:46 PM
A team of engineers and chemists has taken a major step forward in the development of microbial fuel cells -- a technology that utilizes natural bacteria to extract electrons from organic matter in wastewater to generate electrical currents.

Urban stormwater study finds little difference between managed, unmanaged flows

Thursday September 16th, 2021 06:28:43 PM
At a time when many municipalities are seeking to control urban stormwater by investing heavily in green infrastructure -- such as water-quality ponds, infiltration basins, porous pavement and riparian plantings -- a new study suggests that these expensive efforts may not have much of an impact.

Study reveals gophers’ biofluorescence

Thursday September 16th, 2021 06:28:33 PM
You can learn a lot about animals by simply watching them. But some secrets can only be revealed in the dark ... with an ultraviolet flashlight.

How to catch a perfect wave: Scientists take a closer look inside the perfect fluid

Thursday September 16th, 2021 06:28:08 PM
Scientists have reported new clues to solving a cosmic conundrum: How the quark-gluon plasma -- nature's perfect fluid -- evolved into the building blocks of matter during the birth of the early universe.

Good for groundwater – bad for crops? Plastic particles release pollutants in upper soil layers

Thursday September 16th, 2021 06:28:00 PM
In agriculture, large quantities of nano- and microplastics end up in the soil through compost, sewage sludge and the use of mulching foils. The plastic particles always carry various pollutants with them. However, they do not transport them into the groundwater, as is often assumed. Environmental geoscientists have now determined that the plastic particles release the pollutants in the upper soil layers: they do not generally contaminate the groundwater, but have a negative effect on soil microbes and crops.

True behavior of the ‘pleasure molecule’ will reshape how we treat psychiatric diseases and addiction

Thursday September 16th, 2021 05:13:12 PM
Discovery shows that dopamine is not a reward molecule at all, calling for revision of textbook facts regarding the hormone's role in the brain.

Ultrathin self-healing polymers create new, sustainable water-resistant coatings

Thursday September 16th, 2021 04:40:26 PM
Researchers have found a way to make ultrathin surface coatings robust enough to survive scratches and dings. The new material, developed by merging thin-film and self-healing technologies, has an almost endless list of potential applications, including self-cleaning, anti-icing, anti-fogging, anti-bacterial, anti-fouling and enhanced heat exchange coatings, researchers said.

Researchers explore promising treatment for MRSA 'superbug'

Thursday September 16th, 2021 04:40:20 PM
A new study has found the antimicrobial properties of certain stem cell proteins could offer a potential treatment to reduce infection in skin wounds.

Part of the Universe’s missing matter found

Thursday September 16th, 2021 03:46:21 PM
Galaxies can receive and exchange matter with their external environment thanks to the galactic winds created by stellar explosions. An international research team has now mapped a galactic wind for the first time. This unique observation helped to reveal where some of the Universe's missing matter is located and to observe the formation of a nebula around a galaxy.

Research reveals drug targets for memory enhancement

Thursday September 16th, 2021 03:46:11 PM
New research has identified specific drug targets within the neural circuits that encode memories, paving the way for significant advances in the treatment of a broad spectrum of brain disorders.
