How Cells Use Mechanical Tension Sensors to Interact With Their Environment

In a painstaking experiment, scientists suspended a single protein filament between two microscopic beads. Their results have shed light on an elusive process in which cells receive and respond to ...

Can Scientists Take the STING out of Common Respiratory Viruses?

Scientists have made a curious discovery about a well-known human protein that helps the immune system fight viral infections. Researchers found that one class of viruses actually requires this ...

Research Provides a New Understanding of How a Model Insect Species Sees Color

Through an effort to characterize the color receptors in the eyes of the fruit fly Drosophila melanogaster, researchers discovered the spectrum of light it can see deviates significantly from what ...

New Imaging Method Reveals HIV's Sugary Shield in Unprecedented Detail

Scientists have devised a method for mapping in unprecedented detail the thickets of slippery sugar molecules that help shield HIV from the immune system. Mapping these shields will give researchers ...

Elkhorn Coral Actively Fighting Off Diseases on Reef

As the world enters a next wave of the ongoing COVID-19 pandemic, we are aware now more than ever of the importance of a healthy immune system to protect ourselves from disease. This is not only true ...

Seabird Response to Abrupt Climate Change 5,000 Years Ago Transformed Falklands Ecosystems

A 14,000-year paleoecological reconstruction of the sub-Antarctic islands has found that seabird establishment occurred during a period of regional cooling 5,000 years ago. Their populations, in ...

SPOTlight Supercharges Cell Studies

Researchers develop a new method to isolate specific cells, and in the process find a more robust fluorescent ...

Protective Shield: Membrane-Attached Protein Protects Bacteria and Chloroplasts from Stress

Stress is present everywhere, even bacteria and plant cells have to cope with it. They express various specific stress proteins, but how exactly this line of defense works is often not clear. A group ...

Endangered Vaquita Remain Genetically Healthy Even in Low Numbers

The critically endangered vaquita has survived in low numbers in its native Gulf of California for hundreds of thousands of years, a new genetic analysis has found. The study found little sign of ...

Researchers Reveal Why Heat Stress Damages Sperm

DNA in Fringe-Lipped Bat Feces Reveals Unexpected Eating Habits

By examining the guano of the fringe-lipped bat (Trachops cirrhosus), biologists encountered surprising results about its eating habits and foraging ...

Tackling Alarming Decline in Nature Requires 'Safety Net' of Multiple, Ambitious Goals

A 'safety net' made up of multiple ambitious and interlinked goals is needed to tackle nature's alarming decline, according to an international team of researchers analyzing the new ...

Discoveries Reshape Understanding of Gut Microbiome

New findings could lead to new therapies for IBD and people who've had portions of their bowels removed due to conditions like colon cancer and ulcerative ...

Ancient Origins of Speed Control During Movement

Movement in animals is complex. Little has been known about how spinal inhibitory interneurons work to silence other neurons and related muscle groups in coordination with the active muscle groups ...

High-Quality Cat Genome Helps Identify Novel Cause of Dwarfism

A new and improved cat genome has already proven to be a valuable tool for feline biomedical research by helping to confirm existing gene variants and new candidate genes underlying diseases in ...

Finally, a Way to See Molecules 'Wobble'

Researchers have found a way to visualize those molecules in even greater detail, showing their position and orientation in 3D, and even how they wobble and oscillate. This could shed invaluable ...
