Intelligent sensors created for quality-assured cell production

Whether for drug screening or toxicity testing, stem cell-based 3D tissue models are key to biomedical research. However, producing cell aggregates in bioreactors is highly complex and cost-intensive. Until now, quality has ...

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 ...

Common gut bacteria identified as cause of pig ear necrosis

It's a problem that's made its way through pig farms around the world for decades, with no clear cause or solution. But new research from the University of Saskatchewan (USask) has identified the cause of pig ear necrosis, ...
