New type of photosynthesis discovered

The discovery changes our understanding of the basic mechanism of photosynthesis and should rewrite the textbooks. It will also tailor the way we hunt for alien life and provide insights into how we could engineer more efficient crops that take advantage of longer wavelengths of light. The discovery, published today in Science, was led by Imperial …

“Useless” DNA changes the genitals you’re born with

Male mice grow ovaries instead of testes if they are missing a small region of DNA that doesn’t contain any genes — a finding that could help explain disorders of sex development in humans, at least half of which have an unknown genetic cause.

Psychedelic Drugs Can Repair Broken Neural Networks

Could psychedelic drugs one day play a part in the treatment of mental health conditions? The idea is getting less and less far-fetched, after scientists successfully used drugs including MDMA and LSD to repair neurons in animal tests and cultured cells. In small microdoses tested on rats, flies, and zebrafish, the substances sparked new growth in neurites, the bridges between neurons …

A Compound Found In Cannabis Can Treat Epilepsy

Cannabidiol (CBD), a compound derived from the cannabis can treat epilepsy. Cannabidiol which does not produce a “high” and has been an increasing focus of medical research, was shown in a new large-scale, randomized, controlled trial to significantly reduce the number of dangerous seizures in patients with a severe form of epilepsy called Lennox–Gastaut syndrome. …
