Vagus nerve stimulation may enhance long-term motor learning

Do you ever feel like sometimes you can master a new dance step almost immediately, while other times you struggle to nail it despite repeated practice? This might be due to skill or effort, but also to something less obvious: whether the brain is in a state that allows learning to take hold.

New molecular pathway explains why eye pressure rises at night

Glaucoma is an eye disease that causes progressive damage to the optic nerve, leading to loss of sight. One major risk factor is an increase in intraocular pressure (IOP), or the pressure inside the eye.

Loneliness can reprogram the brain to increase alcohol use

Loneliness can reprogram the brain in ways that push alcohol consumption, reports a new preclinical study led by Northwestern University and the Salk Institute for Biological Studies.

Type 2 diabetes mechanisms differ significantly based on patient BMI

Research published today in Diabetologia by Amsterdam UMC and the University of Ghana reveals that type 2 diabetes manifests in two fundamentally different ways depending on a patient's body mass index (BMI).

Wake-activated brain circuits reveal what drives the urge to sleep

Researchers identified wake-activated neurons in the median raphe and anterior medial preoptic area that track sleep pressure and help regulate when and how deeply mice sleep. Manipulating these circuits altered NREM sleep, sleep-pressure accumulation, and rebound sleep, revealing key neural mechanisms underlying mammalian sleep homeostasis.

Active screening cuts colorectal cancer death risk drastically

People who take part in screening for colorectal cancer may have as much as 43 per cent lower risk of dying from the disease, according to new estimates published in JAMA Network Open by researchers at Karolinska Institutet and Umeå University in Sweden.

New AI spots hypertrophic cardiomyopathy obstruction from standard ultrasounds

Mayo Clinic researchers have developed and externally validated an artificial intelligence (AI) model that can identify a potentially significant heart obstruction from routine ultrasound videos without relying on specialized Doppler imaging.

Infants' sense of agency develops through culture-specific caregiver interactions

A baby sits on the floor and reaches toward a red ball on a floor and grunts. The mother responds, "Do you see the ball?" She picks it up and holds it in front of baby and says, "Do you want to hold the ball?" The baby shrieks in excitement as the mother hands the ball to the baby.

Paying attention to your body may change how an acute skin inflammation unfolds

Voluntary attention to inflammation-related bodily sensations reduced the magnitude of histamine-induced skin inflammation and promoted faster resolution compared with distraction in healthy adults. The findings point to complementary sensory-dependent and top-down autonomic pathways, although the precise neural and immune mechanisms remain unresolved.

Improved indoor lighting may prevent nearsightedness in children

Research has already shown that the more time children spend playing with screens indoors instead of playing outdoors, the more likely they are to develop myopia.

Five-week training program helps college students regulate their emotions

A five-week training intervention taught college students to better regulate their emotions in response to negative events, a new study finds.

Wearable sensors coupled with AI can non-invasively monitor blood pressure

Wearable sensors coupled with AI can generate blood pressure readings nearly as well as the invasive and risky arterial lines relied on in intensive care units and operating rooms, new work by Johns Hopkins University researchers demonstrates.

AI-based "tissue clocks" measure the biological age of human organs

AI-based "tissue clocks" can estimate the biological age of human organs from histological images, researchers at the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences and the Ludwig Boltzmann Institute for Network Medicine (LBI-NetMed) at the University of Vienna showed.

Neuroscientists study the brain circuits mediating experience-dependent decision-making in mice

A brain must constantly cope with the highly variable, fast-paced nature of the world when trying to judge what's going on around it.

Studies link traumatic brain injury to high mortality in Pakistan

Traumatic brain injury (TBI) in Pakistan is associated with a high risk of death and disability long after the initial injury, even in mild to moderate cases, according to two new studies in JAMA Network Open led by Weill Cornell Medicine researchers.

Researchers identify genes that hinder CRISPR editing efficiency

Like a delivery driver navigating crowded city streets, a gene-therapy-toting lipid nanoparticle faces a gauntlet of potential detours on its journey toward a cell's nucleus.

New 3D imaging system captures seizures in real time

A seizure is a sudden, overwhelming wave of electrical energy passing through the brain in a matter of seconds - so fast, in fact, that it's been nearly impossible to fully capture where these electrical bursts originate, how they move and where they stop.

UC San Diego and West Health launch new national healthcare model

America's health care system is under pressure with demand rising, hospital capacity strained and the number of patients who need care the most increasing faster than the system was built to serve.

Genetic tool turns soft cancer cells into immune targets

Researchers at the USC Viterbi School of Engineering and Keck School of Medicine of USC have engineered a remarkable genetic tool that addresses one of the most persistent obstacles in cancer immunotherapy: the physical softness of tumors.

Miniature microscope tracks and activates single brain cells during movement

Researchers at the University of Colorado Anschutz and the University of Colorado Boulder have developed a miniature microscope that allows scientists to observe and activate individual brain cells during natural movement, an advance that could accelerate research into how the brain controls behavior while deepening understanding of neurological diseases.
