New cellular protective mechanism discovered

A vast number of biological reactions occur inside cells, generating various byproducts. Some of these can be highly reactive molecules, and if they build up inside cells they can cause stress and damage. One class of these ...

Key regulator of cell growth deciphered

The mTOR protein plays a central role in cell growth, proliferation and survival. Its activity varies according to the availability of nutrients and some growth factors, including hormones. This protein is implicated in several ...

Lipid expansion microscopy uses 'power of click chemistry'

Lipids—fats—make great walls for cells and organelles because they are water resistant and dynamic. But those same characteristics also make them hard to image using expansion microscopy, a technique that works for magnifying ...

Protein family shows how life adapted to oxygen

Cornell scientists have created an evolutionary model that connects organisms living in today's oxygen-rich atmosphere to a time, billions of years ago, when Earth's atmosphere had little oxygen—by analyzing ribonucleotide ...

Better understanding of cellular metabolism with the help of AI

Metabolism is essential to all living organisms, and modeling the chemical reactions that sustain life is no easy task. Now, EPFL scientists have released REKINDLE, a deep-learning process that is paving the way for more ...

Prions: New possible therapeutic target discovered

Prion diseases, such as bovine spongiform encephalopathy ("mad cow disease"), are lethal neurodegenerative infectious diseases that affect humans and other mammals and for which there is currently no cure.
