In living cells, regulation of the electrochemical environment is supposed to be managed by ion channels—protein complexes that reside in cell membranes and assume definite shapes. So, it’s surprising ...

Stem cells age faster and become functionally exhausted in low Earth orbit, making crewed long-duration space travel even more challenging. When you purchase through links on our site, we may earn an ...

It’s not surprising that many people fear the dentist. Replacing a tooth often requires invasive surgery and implanting a titanium screw into a patient’s jawbone, then waiting months for that to ...

Bioengineers have developed a new construction kit for building custom sense-and-respond circuits in human cells. The research could revolutionize therapies for complex conditions like autoimmune ...

Even after decades of peering into cells, biologists are still finding surprises. In a twist, researchers at the University of Virginia and the National Institutes of Health uncovered a new organelle, ...

Cells are not immortal, and that is a good thing. After a certain number of divisions, many human cells stop multiplying for good. They enter a state called replicative senescence, where growth ceases ...

Typically, bone marrow research relies heavily on animal models and oversimplified cell cultures in the laboratory. Now, researchers from the Department of Biomedicine at the University of Basel and ...

The most complex engineering of human cell lines ever has been achieved by scientists, revealing that our genomes are more resilient to significant structural changes than was previously thought. The ...

Scientists have discovered that H5N1, the strain of highly pathogenic avian influenza virus currently spreading in U.S. dairy cows, only needs a single mutation to readily latch on to human cells ...
