Researchers at Rutgers and Emory University are gaining insights into how schizophrenia develops by studying the strongest-known genetic risk factor.

When a small portion of chromosome 3 is missing—known as 3q29 deletion syndrome—it increases the risk for schizophrenia by about 40-fold.

Researchers have now analyzed overlapping patterns of altered gene activity in two models of 3q29 deletion syndrome, including mice where the deletion has been engineered in using CRIPSR, and human brain organoids, or three-dimensional tissue cultures used to study disease. These two systems both exhibit impaired mitochondrial function. This dysfunction can cause energy shortfalls in the brain and result in psychiatric symptoms and disorders.

The tiny needle, called a nanopipette, allows researchers to take a biopsy of a living cell several times while it receives treatment without killing it — and could lead to new cancer cures.

Early diagnosis and better awareness mean tumours can be caught early – and when disease is found, under-45s can often tolerate chemotherapy better.

A century ago, Emmy Noether published a theorem that would change mathematics and physics. Here’s an all-ages guided tour through this groundbreaking idea.

In dim light a cat sees much better than you do, as do dogs and nocturnal animals. That’s because the structure of a cat’s eye has a tapetum lucidum, a mirror-like layer immediately behind the retina. Light entering the eye that is not focused by the lens onto the retina is reflected off the tapetum lucidum, where the retina gets another chance to receive the light, process it, and send impulses to the optic nerve.

Research led by Macquarie University sheds new light on how concentrations of metals used in renewable energy technologies can be transported from deep within the Earth’s interior mantle by low temperature, carbon-rich melts.

The use of artificial intelligence in the development of video games has been met with both excitement and dread.

According to a recent industry report by game engine developer Unity, studios are already using AI to save time and boost productivity by whipping up assets and code.

But given enough time, the video games of the future could soon be entirely created with the use of AI — maybe even within just ten years, according to Nvidia CEO Jensen Huang, the man behind a company that’s greatly benefitting from selling thousands of graphics processing units (GPUs) to some of the biggest players in the AI industry.
