COVID-19 virus uses heparan sulfate to get inside cells

1 week ago from Physorg

A molecule known as ACE2 sits like a doorknob on the outer surfaces of the cells that line the lungs. Since January 2020, researchers have known that SARS-CoV-2, the novel...

Biodiversity bright spots offer hope despite failure to meet UN goals

All the world's governments have fallen short on pledges made a decade ago to protect wildlife, though cases of conservation show that the destruction of nature can be slowed, and...

Marines test shorter, more realistic advanced rifle qualification

The U.S. Marine Corps is testing a new, shorter, more realistic shooting qualification, the service announced Tuesday.

New dopamine sensors could help unlock the mysteries of brain chemistry

1 week ago from Science Daily

Scientists developed dLight1, a single fluorescent protein-based biosensor. This sensor allows high resolution, real-time imaging of the spatial and temporal release of dopamine in live animals. Now, the team expanded...

Human white blood cells use molecular paddles to swim

1 week ago from Science Daily

Human white blood cells, known as leukocytes, swim using a newly described mechanism called molecular paddling, researchers report. This microswimming mechanism could explain how both immune cells and cancer cells...

Real neurons are noisy: Can neural implants figure that out?

1 week ago from Science Daily

Signals sent from the retina to the brain have a lot of background noise, yet we see the world clearly. Researchers show that to achieve visual clarity the brain must...

A new bacterial molecule with the unsavory tendency to track down and kill others of its own kind has been discovered in the human microbiome by researchers at Princeton's Department...

Successful improvement of the catalytic activity of photosynthetic carbon dioxide fixing enzyme Rubisco

1 week ago from Physorg

A research group consisting of Associate Professor Fukayama Hiroshi (Kobe University, Graduate School of Agricultural Science) and Professor Matsumura Hiroyoshi (Ritsumeikan University) et al. have succeeded in greatly increasing the...

Rare pattern observed in migrating common swifts

1 week ago from Physorg

Compared with other migratory birds, the common swift follows a very unusual pattern when it migrates from the breeding areas in Europe to its wintering locations south of the Sahara....

Tiny protein motor fuels bacterial movement

1 week ago from Science Daily

The ability to move is key for bacteria like some strains of salmonella and E. coli to efficiently spread infections. They can propel themselves forward using threads, known as flagella,...

Chimpanzees show greater behavioral and cultural diversity in more variable environments

1 week ago from Science Daily

Scientists have investigated the influence of environmental variability on the behavioral repertoires of 144 social groups. The scientists found that chimpanzees living further away from historical forest refugia, under more...

New shark research targets a nearly endangered species

1 week ago from Science Daily

They are some of the most iconic and unique-looking creatures in our oceans. While some may think they look a bit 'odd,' one thing researchers agree on is that little...

Possible genetic link found between hypothyroidism and development of canine T-zone lymphoma

1 week ago from Physorg

A genetic mutation might be the reason dogs with hypothyroidism are less likely to develop T-zone lymphoma (TZL). That's the finding from Morris Animal Foundation-funded researchers at Colorado State University who tried...

Chimpanzees show greater behavioural and cultural diversity in more variable environments

1 week ago from Physorg
