People with Alzheimer’s exhibit a loss of motor control along with cognitive decline, and one of the earliest signs of this decay can be spotted in involuntary eye movements known as saccades. These quick twitches of the eyes in Alzheimer’s patients are often slower, less accurate, or delayed compared to those in healthy individuals.
Up until recently, habituation — a simple form of learning — was deemed the exclusive domain of complex organisms with brains and nervous systems, such as worms, insects, birds, and mammals. But a new study, published Nov. 19 in Current Biology, offers compelling evidence that even tiny single-cell creatures such as ciliates and amoebae, as well as the cells in our own bodies, could exhibit habituation akin to that seen in more complex organisms with brains.
A new method to increase fusion-fuel efficiency would involve aligning the quantum spin of deuterium and tritium and changing the mix of the two fuels. The approach could boost tritium-burn efficiency by up to 10 times, reducing tritium needs and lowering fusion system costs. The technique could lead to safer, more compact fusion systems, making fusion energy more practical and affordable.
Lawrence Livermore National Laboratory (LLNL), in collaboration with the National Nuclear Security Administration (NNSA), Hewlett Packard Enterprise and AMD, have officially unveiled El Capitan as the world's most powerful supercomputer and first exascale system dedicated to national security.
One in seven parents think their child gets angrier than peers of the same age and four in 10 say their child has experienced negative consequences when angry, a new national poll suggests.
U.S. President-elect Donald Trump has promised to close the Department of Education. ...
New research sheds light on a surprising connection between COVID-19 and cancer regression
In 2023, the United States Department of Agriculture's (USDA) Economic Research Service reported that 13.5% of U.S. households were food insecure at some point during the year. The USDA defines this as households that were uncertain of having, or unable to acquire, enough food to meet the needs of all their members due to insufficient money or other resources for food.
Joshua Yuan, Susie Dai and colleagues at Washington University and Texas A&M create biodiesel with electrocatalysis and bioconversion.
Relief is coming for crime scene investigators and toxicologists who have struggled to accurately and swiftly identify drugs that have been seized by law enforcement and may be relied on as evidence at trial, thanks to a research partnership between West Virginia University and the U.S. Drug Enforcement Administration.
Hubble witnessed a dwarf galaxy crashing through the Milky Way galaxy's gaseous halo and living to tell the tale...though a bit worse for wear!
A small clinical trial shows promising results for patients with triple-negative breast cancer who received an investigational vaccine designed to prevent recurrence of tumors. Conducted at Washington University School of Medicine in St. Louis with a therapy designed by WashU Medicine researchers, the trial is the first to report results for this type of vaccine — known as a neoantigen DNA vaccine — for breast cancer patients.
University of Maryland School of Medicine Researchers Identify Neurobiological Changes Leading to Increase Release of the Brain Chemical Dopamine and Its Target Neurons Linked to Addiction-Like Behavior With the increased legalization of recreational cannabis, as many as 1 in 5 pregnant women in the U.S. are now using the drug to help with morning sickness, lower back pain or anxiety.
ARRIVE Together of Middlesex County, NJ, run by University Behavioral Health Care (UBHC) at Rutgers Health, has expanded its partnerships to include the East Brunswick, South River and Cranbury police departments, making New Jersey the first state in the nation to have a statewide law enforcement and mental health alternative response program.
A recent study published in the journal Scientific Reports correlates higher levels of pollutant particulate matter to higher occurrences of head and neck aerodigestive cancer.
Researchers have developed an AI powered model that — in 10 seconds — can determine during surgery if any part of a cancerous brain tumor that could be removed remains, a study published in Nature suggests. The technology, called FastGlioma, outperformed conventional methods for identifying what remains of a tumor by a wide margin. Researchers say it has the potential to change the field of neurosurgery by immediately improving comprehensive management of patients with diffuse gliomas.
People with conditions or habits such as high blood pressure, an irregular heartbeat called atrial fibrillation, or smoking, not only have a higher risk of stroke, they may also have more severe strokes than people without these risk factors, according to a study published in the November 13, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Newly published research by Grainger Engineers in Mechanical Science and Engineering describes an unprecedented computational model that captures the intricate muscular architecture of an octopus arm.
Vitamin D supplements may lower blood pressure in older people with obesity and taking more than the Institutes of Medicine’s (IOM) recommended daily dose does not provide additional health benefits, according to new research published in the Journal of the Endocrine Society.
A new poll looks at how grandparents are involved in their grandchildren's lives, and how this relates to mental health and lonelines.
