Study links brain region to paranoia – Neuroscience News

by
Neuroscience News logo for mobile.

Resume: Researchers found that a specific brain region, the mediodorsal thalamus, can cause feelings of paranoia. Aligning data from studies in monkeys and humans, they found that lesions in this brain region led to erratic behavior and increased perception of the volatility of the environment. The study provides a new framework for understanding human cognition … Read more

Wild new study suggests gravity can exist without mass

by

What is gravity without mass? Both Newton’s revolutionary laws describing its universal effect and Einstein’s proposal of a dimpled space-time have led us to think of gravity as falling solely within the domain of matter. Now a wild new study suggests that gravity can exist without mass, easily eliminating the need for one of the … Read more

Astronauts are living with a drug-busting ‘superbug’ that mutated in orbit, study says

by

A NEW alien ‘superbug’ has been discovered aboard the International Space Station. Despite the highly controlled environment on the ISS, an insect hitched a ride into space, where scientists were able to observe the mutating pathogen over the course of two years. A mutated, drug-resistant ‘superbug’ has been found aboard the International Space Station.Credit: Getty … Read more

Research shows that the four crew members of Inspiration4, the first ever fully civilian space mission, have become genetically younger during their time in space. But the effects didn’t last long. Scientists are now trying to unravel how the space environment affects human DNA. The Inspiration4 crew members had a packed schedule during their three-day … Read more

Model skeletons of a neanderthal and human

Neanderthal genes found in modern humans may have entered our DNA through an interval of interbreeding that began about 47,000 years ago and lasted nearly 7,000 years, new research shows. Neanderthals were among the most extinct relatives of modern humans (Homo sapiens), with the ancestors of both lineages diverging about 500,000 years ago. More than … Read more

Gravity without mass? New study challenges the existence of hypothetical dark matter – The Debrief

by
gravity

A recent study that poses new challenges to the existence of dark matter suggests that gravity can exist even in the absence of mass. Although all life on Earth experiences its effects every day, gravity remains one of the great mysteries of modern physics. Now, a new study published by Dr. Richard Lieu of the … Read more

Once-in-2,000-year event: Study explains unprecedented ice loss in Antarctica, equivalent to 10x the size of Britain

by
SciTechDaily

In 2023, Antarctic sea ice fell to historically low levels, prompting researchers to use CMIP6 climate models to assess the rarity of the event and its link to climate change. The study found that without climate change such a drastic reduction would be extremely rare, but current climate conditions made it more likely. The research … Read more
