The cost of memory: How organisms balance thinking and sensing
Remembering the past can help living organisms make better decisions, but memory comes at a cost. Whether it is an animal searching for food or a single cell responding to its surroundings, storing and using information requires ...

AI-designed SARS-CoV-2 variants escape prevalent antibodies
While headlines warn that AI could unleash future biological threats, the technology also offers our best defense: a way to anticipate viral evolution and stress-test treatments. Rather than waiting for SARS-CoV-2 to mutate ...
Similarity between human and bovine cells could advance drug discovery
Apoptosis is the natural process by which damaged or no longer needed cells are eliminated from the body. Researchers have long investigated how this mechanism might be manipulated to treat cancer and other serious diseases.

A lipid switch that blocks anthrax from entering cells
Every cell carefully builds and positions thousands of proteins that allow it to sense and respond to its surroundings. Even small changes to these proteins often determine whether they work properly or are destroyed before ...

New Ribo-Tweezer tool can pluck individual protein pieces out of a working ribosome
Every human cell has millions of ribosomes that make proteins. For decades, biologists thought of ribosomes as tiny, uniform machines. But now a Stanford Medicine team is showing that ribosomes are much more interesting and ...

Review explains links between plasmids, horizontal gene transfer and antimicrobial resistance
The arms race between bacteria and antibiotics is nothing new—antimicrobial resistance has been an emerging issue in human and animal health for a long time. But in a new review published in JAC-Antimicrobial Resistance, ...

Cracking the axolotl code: How to regrow limbs and stay young
Minor cuts and scrapes usually heal in time, but losing a finger or a whole limb? For most vertebrates, that's a done deal. Unless, of course, you've got the self-healing machinery of an axolotl.

Molecular switch that activates cell growth signaling may offer more precise route for anticancer therapy
Cells carry their own growth switches. When enough nutrients—amino acids in particular—are available, cells flip this switch on and begin to grow. Researchers at KAIST and Yonsei University have uncovered the molecular mechanism ...

Prolonged stretching reorganizes tissue scaffolds and uncages cell nuclei
How do tissues cope with being stretched for hours or even days? A study led by researchers at the Institute for Bioengineering of Catalonia (IBEC) has uncovered an unexpected answer: Cells radically reorganize their internal ...

First 3D views explain how primate cone pigments distinguish red from green
Human color vision depends on three types of cone cells in the retina. Although all three contain the same light-absorbing molecule, 11-cis-retinal, differences in the surrounding protein determine sensitivity to red, green ...

Researchers uncover new mechanism behind DNA repair
Roughly 20 million people receive a cancer diagnosis each year, and an estimated 1 in 5 people will receive a cancer diagnosis in their lifetime. Cancer cells arise from damage to the cell's instruction manual: DNA.

AI finds tiny gene editor changes that reduce unintended DNA edits
Gene editing is a highly precise and powerful technology that allows scientists to insert, delete, modify or replace DNA bases in living organisms. It has a variety of uses, including correcting disease-causing mutations ...
Scientists pinpoint where cells first begin copying DNA
Researchers at the MRC Laboratory of Medical Sciences (LMS) and collaborators have uncovered one of the earliest steps in DNA replication: the moment a cell first opens its DNA to begin making a copy of its genome. The findings, ...
