'Molecular movie' fills in blanks of how nonenveloped viruses infect cells
Viruses come in two major flavors—not chocolate and vanilla, quips Harvard Medical School structural biologist Stephen Harrison, but those enveloped in membranes, such as herpesvirus, influenza virus, HIV and SARS-CoV-2, ...

Longer lives despite mitochondrial defects? Worms rely on calcium-triggered 'cages'
If your car's engine develops a stutter, that's generally a sign that you should go to a mechanic before it stops running. We tend to think the same way about our bodies: When something's broken, something bad usually follows. ...

Chlamydia packs DNA with lipids, revealing possible target for blocking infection
The bacterium Chlamydia trachomatis is one of the most common causes of sexually transmitted infections worldwide. Biologically, it is regarded as a highly specialized "nutrient thief": Because chlamydia have lost the ability ...

Wild crabapples have genetic potential to improve domestic varieties
A bad apple doesn't always ruin the bunch. In fact, it might make the bunch a little stronger. A new study published in Horticulture Research by Ben Mansfeld, an assistant professor of biology in Arts & Sciences at Washington ...

Wild tomatoes still hold the flavor we bred away: New map shows breeders where to look
Modern tomatoes are a breeding success story. Generations of selection have made them bigger, firmer, more productive and easier to ship. But that progress came at a cost. Domestication and breeding reduced much of the crop's ...

Genetic audit of wheat: Researchers determine the actual variability of a gene responsible for bread quality
A team at the University of Córdoba (UCO) has reviewed and updated the catalog of versions of the wheat gene GLU-B1, which is responsible for a protein that makes up gluten. The team has also made a collection of wheat representing ...

Protein signaling cascade helps explain how plants respond to touch
Plants cannot run away when the wind picks up, rain lashes down or a hungry herbivore begins chewing on their leaves. Instead, they must sense their surroundings and adapt. Now, researchers have uncovered an important piece ...

The molecular mechanism that regulates TMEM63B lipid scrambling
TMEM63B, a mechanosensitive lipid scramblase, has an autoinhibitory domain in its C-terminal tail that helps keep it inactive under resting conditions, researchers from the Institute of Science Tokyo report. Changes to this ...

How bumblebees keep up with a flower that won't stay still
Landing on a moving target is a challenge for all flying animals. For bumblebees, a flower swaying in the wind creates an erratic landing pad. Reaching it means matching its sideways motion while continuing to face it. When ...
Whole genome duplication shaped the evolution of the salmon family
Evolution is driven by changes in DNA that sometimes promote adaptation, altering traits like disease resistance or reproduction. Often, these changes are minuscule, modifying a single letter in the DNA code—somewhat like ...
