A new Alzheimer’s test collects just a few drops of blood from a finger prick, which can be mailed to a lab for analysis. The test measures biomarkers like pTau217 and has shown similar accuracy to traditional venous blood sampling.
Scientists have reprogrammed mouse cells into pluripotent stem cells using a gene from choanoflagellates, single-celled organisms related to animals. This breakthrough demonstrates that key genes driving stem cell formation existed in...
Rest tremor in Parkinson’s disease is linked to dopamine activity in the caudate nucleus, challenging conventional beliefs about dopamine loss and motor symptoms. Surprisingly, patients with stronger tremor preserved more dopamine in the...
A new study explores how robots can model and test aspects of the human sense of self, offering new insights into this complex phenomenon. Robots can simulate processes like body ownership and agency, or be used in experiments to study...
Fampridine is currently used to improve walking ability in multiple sclerosis. A new study shows that it could also help individuals with reduced working memory, as seen in mental health conditions like schizophrenia or depression.
Alcohol-related deaths in the U.S. nearly doubled from 1999 to 2020. The sharpest spike occurred among 25- to 34-year-olds (nearly fourfold), while individuals aged 55 to 64 had the highest rates. Men consistently had higher rates but...
Recent research suggests the unique stresses from farm life may be taking a toll on one of the pillars of the families that make your dinners possible: the women who keep farming families running.
Scientists reveal how sleep, especially naps, boosts motor learning after TBI, offering new insights into brain activity and rehabilitation strategies to enhance recovery outcomes.
It turns out gaming is good for you! New research indicates massive multiplayer online gamers learn by gaming and their skills in the workplace are enriched by those seemingly endless hours previously thought of as frittering away time.
Leading researchers warn that relying on "passive" carbon sinks such as forests to absorb ongoing carbon emissions will doom the world to continued warming
Researchers have identified the structure of amyloid beta fibrils linked to a rare inherited form of Alzheimer’s disease caused by the Arctic mutation. Using cryo-electron microscopy and NMR, they revealed a W-shaped fibril structure...
Self-consciousness about one’s body affects the ability to learn and perform movement tasks, according to new research. Participants recalling body-related embarrassment performed worse on motor tasks compared to those recalling pride,...
Researchers have developed a dual-gene therapy approach to treat Usher syndrome type 1F, a rare condition causing deafness and progressive blindness. By splitting the large PCDH15 gene into two halves, delivering them via...
Astrocytes, critical brain cells, are often lost in neurodegenerative diseases, but recent research highlights the promise of astrocyte transplantation to restore brain function. These transplanted cells integrate into the host brain,...
New research has found no evidence linking heart rate variability (HRV) to reactive aggression, overturning previous theories. HRV measures the variation between heartbeats and has been associated with stress resilience, but this study...
A study modelling the impact of melting ice suggests scientists have underestimated the risk that an important ocean current will shut down and cause climate chaos
Clinical visits by patients suffering ocular surface eye conditions more than doubled during times when ambient particulate matter from air pollution was in the atmosphere, signaling a possible association between climate change and...
A new study shows that the past 30 years of globalization have brought fundamental shifts in some aspects of family interaction among Indigenous people in Guatemala. But families have still maintained a unique level of harmony in their...
Children born to mothers who take antiseizure medications to manage seizures and psychiatric conditions during pregnancy may face increased risks of neurodevelopmental conditions, according to new research.
Scholars for the first time identified chemical signatures of the components of a liquid concoction contained in a Bes mug. A new technique helped identify a sample flavored with honey, sesame seeds, pine nuts, licorice and grapes --...
A study found that people are less likely to consume cannabis if they had an upcoming activity, which is consistent with other studies, and would reduce use the most for job interviews and caring for children. However, people who rated...
Stress is a double-edged sword when it comes to memory: stressful or otherwise emotional events are usually more memorable, but stress can also make it harder for us to retrieve memories. Now, neuroscientists report that acute stress...
In a new study, researchers identify the biological processes behind stress-induced aversive memory generalization and highlight an intervention which could help restore appropriate memory specificity for people with PTSD.
Researchers found that spending two hours a week of class time in a natural environment can reduce emotional distress among 10- to 12-year-olds who had the most significant mental health problems before the program began.
Letting AI models communicate with each other in their internal mathematical language, rather than translating back and forth to English, could accelerate their task-solving abilities
Water levels in the Caspian Sea are set to fall dramatically as the climate gets hotter, posing a major threat to economic activity and ecosystems in the region
Two massive galaxies are bending light from the same distant quasar, creating a so-called Einstein zigzag lens that could help astronomers pin down how quickly the universe is expanding
It has been 50 years since archaeologists discovered Lucy, perhaps the most famous ancient hominin ever found. But the scientists who have studied her say that this fossil gave us a misleading image of the nature of her species
A classic study found that people can fail to notice a gorilla when they are focusing on something else, but new experiments suggest this "inattentional blindness" might not tell the whole story
Researchers have linked disease-related proteins and genes to identify specific cellular pathways responsible for Alzheimer's genesis and progression. The proteins were gathered from cerebrospinal fluid and are a good proxy for activity...
An international team of leading neuro-oncology researchers and clinicians has released new recommendations for good clinical practice regarding the use of artificial intelligence methods to more accurately diagnose, monitor and treat...
New research found that the use of standardized autism screening during pediatric well-child visits identifies more children with high autism likelihood at a younger age, including those presenting with more subtle symptoms.
