Quorum sensing molecules: How the body cells spy out bacteria

Bacterial infection does not automatically lead to illness; many germs only become dangerous when they occur in large numbers. Researchers at the Max Planck Institute for Infection Biology in Berlin have discovered that the ...

How large can a planet be?

Jupiter is the largest planet in the solar system. In terms of mass, Jupiter dwarfs the other planets. If you were to gather all the other planets together into a single mass, Jupiter would still be 2.5 times more massive. ...

SciLifeLab and AstraZeneca use cryo-EM to advance biomedicine

A study published in Science Advances reveals the mechanism by which the receptor tyrosine kinase RET can increase neuronal survival in degenerative diseases. To understand the mechanism of this signalling complex, the study ...

When kinetics and thermodynamics should play together

The formation of calcium carbonate (CaCO3) in water has ramifications for everything from food and energy production to human health and the availability of drinkable water. But in the context of today's environment, simply ...

When will a neutron star collapse to a black hole?

Neutron stars are the most extreme and fascinating objects known to exist in our universe: Such a star has a mass that is up to twice that of the sun but a radius of only a dozen kilometres: hence it has an enormous density, ...

Research shows relationship critical for how cells ingest matter

To survive and fulfill their biological functions, cells need to take in material from their environment. In this process, proteins within the cell pull inward on its membrane, forming a pit that eventually encapsulates the ...
