By scanning the brains of people while they watched movie clips, neuroscientists have created the most detailed functional map of the brain to date. The fMRI analysis shows how different brain networks light up when participants viewed short clips from a range of independent and Hollywood films including Inception, The Social Network, and Home Alone. The team identified different brain networks involved in processing scenes with people, inanimate objects, action,... Read more ›

A new study changes the way we understand memory. Until now, memories have been explained by the activity of brain cells called neurons that respond to learning events and control memory recall. Neurologists have now expanded this theory by showing that non-neuronal cell types in the brain called astrocytes -- star-shaped cells -- also store memories and work in concert with groups of neurons called engrams to regulate storage and...

Thin, flexible device could help people with visual impairments 'feel' surroundings. Device comprises a hexagonal array of 19 actuators encapsulated in soft silicone. Device only uses energy when actuators change position, operating for longer periods of time on a single battery charge. Read more ›

Researchers have developed AI-driven mobile robots that can carry out chemical synthesis research with extraordinary efficiency. Researchers show how mobile robots that use AI logic to make decisions were able to perform exploratory chemistry research tasks to the same level as humans, but much faster. Read more ›

Scientists have demonstrated a new way to use high-energy particle smashups at the Relativistic Heavy Ion Collider (RHIC) to reveal subtle details about the shapes of atomic nuclei. The method is complementary to lower energy techniques for determining nuclear structure. It will add depth to scientists' understanding of the nuclei that make up the bulk of visible matter.

Researchers have developed a new method for disrupting the crystal structure of a semiconductor that requires as little as one billion times less power density. This advancement could unlock wider applications for phase-change memory (PCM) -- a promising memory technology that could transform data storage in devices from cell phones to computers. Read more ›

Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before the appearance of the first animals. A team has observed that this species forms multicellular structures that bear striking similarities to animal embryos. These observations suggest that the genetic programs responsible for embryonic development were already present before... Read more ›

Neuroscientists have discovered brain cells that form multiple coordinate systems to tell us 'where we are' in a sequence of behaviors. These cells can play out different sequences of actions, just like a music box can be configured to play different sequences of tones. The findings help us understand the algorithms used by the brain to flexibly generate complex behaviors, such as planning and reasoning, and might be useful in... Read more ›

Tiny grains from asteroid Ryugu are revealing clues to the magnetic forces that shaped the far reaches of the solar system over 4.6 billion years ago. The findings suggest the distal solar system harbored a weak magnetic field, which could have played a role in forming the giant planets and other objects. Read more ›

Some patients being treated with immune checkpoint inhibitors, a type of cancer immunotherapy, develop a dangerous form of heart inflammation called myocarditis. Researchers have now uncovered the immune basis of this inflammation. The team identified changes in specific types of immune and stromal cells in the heart that underlie myocarditis and pinpointed factors in the blood that may indicate whether a patient's myocarditis is likely to lead to death.

Large language models can achieve incredible performance on some tasks without having internalized a coherent model of the world or the rules that govern it, researchers find. This means these models are likely to fail unexpectedly if they are deployed in situations where the environment or task slightly changes. Read more ›

When performing a knee replacement surgery or total knee arthroplasty, doctors traditionally try to align the hip, knee, and ankle in a straight line, forming a neutral alignment, rather than replicating the patient's original alignment. To understand which approach is better, researchers have conducted a post-operation questionnaire comparing patient-reported outcomes to changes in knee alignment before and after surgery. Their findings may improve current surgical guidelines and patients' long-term qualit Read more ›

A new study of more than 1,000 adults, average age 33, found that meeting recommended physical activity guidelines isn't enough to counteract the 60-plus hours per week they spend sitting. To reduce heart disease risk and prevent accelerated aging, they need to sit less and work-out harder. Read more ›
