How a broken DNA repair tool accelerates aging

Although DNA is tightly packed and protected within the cell nucleus, it is constantly threatened by damage from normal metabolic processes or external stressors such as radiation or chemical substances. To counteract this, ...

One of Earth's most abundant organisms is surprisingly fragile

A group of ocean bacteria long considered perfectly adapted to life in nutrient-poor waters may be more vulnerable to environmental change than scientists realized. The bacteria, known as SAR11, dominate surface seawater ...

Bacterial 'brains' operate on the brink of order and disorder

The sensory proteins that control the motion of bacteria constantly fluctuate. AMOLF researchers, together with international collaborators from ETH Zurich and University of Utah, found out that these proteins can jointly ...

Crosstalk inside cells helps pathogens evade drugs, study finds

Biologists have uncovered a new mode of communication inside cells that helps bacterial pathogens learn how to evade drugs. Their findings, published in the journal Nature Communications, describe how these mechanisms drive ...

A peek inside the clockwork that drives embryonic body patterning

The architecture of the body is not encoded as a formal blueprint; rather, it's the tightly orchestrated activation and deactivation of genes that coordinate body development. Many of these processes are not fully understood, ...

A specific immune system protein may drive antibiotic tolerance

If you have had strep throat or an ear infection, there's a good chance you received amoxicillin or penicillin to effectively kill the troublesome bacteria. These drugs, which belong to a broad group of antibiotics called ...

The microbiome of an entire country mapped for the first time

An international research team led by Aalborg University with contributions from the University of Vienna has systematically mapped the microbiome of an entire country for the first time. In the study "Microflora Danica," ...

How cells change their minds and save their work in progress

All cells need to sense and respond to their environment, to know when to activate genes, build proteins, and carry out their basic functions. One of the most well-studied cellular responses is how they react during times ...

C-Compass: AI-based software maps proteins and lipids within cells

A new tool developed by Helmholtz Munich and the German Center for Diabetes Research and the University of Bonn makes spatial proteomics and lipidomics easier to use—no coding required. C-COMPASS allows scientists to profile ...

Human hair grows through 'pulling' not pushing, study shows

Scientists have found that human hair growth does not grow by being pushed out of the root; it's actually pulled upward by a force associated with a hidden network of moving cells. The findings challenge decades of textbook ...

Embryos show specialized asymmetry at the earliest stage

As nearly one in six couples experience fertility issues, in-vitro fertilization (IVF) is an increasingly common form of reproductive technology. However, there are still many unanswered scientific questions about the basic ...
