Alien Life Could Theoretically Survive Within Venus’s Clouds, Scientists Say

by

With an atmosphere acidic enough to strip the skin from your bones, Venus is far from what we might imagine as hospitable. But a new study backs up the idea that cocoons of life could potentially exist in the planet’s corrosive clouds.   Researchers have identified a chemical pathway through which the droplets of sulfuric … Read more

Chemical Air Pollution Morphs Into Something Even More Toxic, Study Shows

There’s a Cancer Treatment That Gives People ‘Night Vision’. Here’s How

by

Among all the different types of cancer treatment, photodynamic therapy – where light is used to destroy malignant cells – might have one of the strangest side effects: Patients are often better able to see in the dark.   Last year, researchers finally figured out why this happens: Rhodopsin, a light-sensitive protein in the retinas in our eyes, interacts with … Read more

DeepMind AI: Machine learning tool helps study strange electrons in chemical reactions

by

Strange so-called fractional electrons are crucial to many chemical reactions, but traditional methods cannot model them – a problem that DeepMind has used machine learning to fix Physics 9 December 2021 By Leah Crane An artistic representation of molecules interacting DeepMind Machine-learning tools have taken us closer to understanding electrons and how they behave in … Read more
