New research shows that trying to stifle boredom at work prolongs its effects and that alternating boring and meaningful tasks helps to prevent the effects of one boring task from spilling over to reduce productivity on others. Read more ›

Young to middle-aged women who reported drinking eight or more alcoholic beverages per week--more than one per day, on average--were significantly more likely to develop coronary heart disease compared with those who drank less, finds a study presented at the American College of Cardiology's Annual Scientific Session. The risk was highest among both men and women who reported heavy episodic drinking, or 'binge' drinking, and the link between alcohol and... Read more ›

How coral populations expand into new areas and sustain themselves over time is limited by the scope of modern observations. Going back thousands of years, a study provides geological insights into coral range expansions by reconstructing the composition of a Late Holocene-aged subfossil coral death assemblage in an unusual location in Southeast Florida and comparing it to modern reefs throughout the region. Findings offer a unique glimpse into what was... Read more ›

People carrying BRCA1 and BRCA2 gene mutations are at high risk of developing breast and ovarian cancer. Researchers have found that changes occur in the immune cells of breast tissue in carriers of BRCA1 and BRCA2 mutations long before breast cancer develops. This raises the possibility of early intervention to prevent the disease, as an alternative to risk-reduction surgery. Drugs already approved for late-stage breast cancer treatment could reactivate the... Read more ›

Researchers have developed a new method to isolate HIV from samples more easily, potentially making it easier to detect infection with the virus. They focus on peptide nanofibrils (PNFs) on magnetic microparticles, a promising tool and hybrid material for targeted binding and separation of viral particles. Read more ›

An analysis of how synaptic proteins change during early development reveals differences between mice and marmosets but also what's different in individuals with autism spectrum disorders. The findings offer first insights into the mechanism behind synaptic development and open up routes for research on possible treatments. Read more ›

Building upon recent findings showing the promise of coating the inner surface of the vessel containing a fusion plasma in liquid lithium, researchers have determined the maximum density of uncharged particles at the edge of a plasma before certain instabilities become unpredictable. The research includes observations, numerical simulations and analysis from their experiments inside a fusion plasma vessel called the Lithium Tokamak Experiment-Beta (LTX- ). This is the first time... Read more ›

Researchers discover that the COVID-19 virus can trigger the production of 'abzymes' -- antibodies that act like enzymes -- which may explain why long COVID symptoms persist even after the infection is cleared. Read more ›

A research team has addressed the long-standing challenge of creating artificial olfactory sensors with arrays of diverse high-performance gas sensors. Their newly developed biomimetic olfactory chips (BOC) are able to integrate nanotube sensor arrays on nanoporous substrates with up to 10,000 individually addressable gas sensors per chip, a configuration that is similar to how olfaction works for humans and other animals.

There has been a redistribution in the risk of arterial disease in type 1 and 2 diabetes. The risks of heart attack and stroke have decreased significantly, while complications in more peripheral vessels have increased in relative importance, according to new studies. Read more ›

Researchers report that mature oligodendrocytes -- the central nervous system cells critical for brain function -- cling to life following a fatal trauma for much, much longer than scientists knew. The findings suggest a new pathway for efforts to reverse or prevent the damage that aging and diseases such as multiple sclerosis cause to these important cells. Read more ›

Researchers have introduced a new, refined method for analyzing brain signals, enhancing our understanding of brain functionality. This research has the potential to improve treatments for neurological conditions such as Parkinson's disease, pain, epilepsy and depression. Read more ›

The interior of the Sun does not rotate at the same rate at all latitudes. The physical origin of this differential rotation is not fully understood. It turns out, long-period solar oscillations discovered in 2021 play a crucial role in controlling the Sun's rotational pattern. The long-period oscillations are analogous to the baroclinically unstable waves in Earth's atmosphere that shape the weather. In the Sun, these oscillations carry heat from... Read more ›

Researchers can use the light naturally thrown off by biological specimens to better study the different states of stem cells in the nervous system, thanks to a tool brightening their chances for studying the way stem cells age. Read more ›

Artificial intelligence (AI) may serve as a future tool for neurologists to help locate where in the brain a stroke occurred. In a new study, AI processed text from health histories and neurologic examinations to locate lesions in the brain. The study looked specifically at the large language model called generative pre-trained transformer 4 (GPT-4). Read more ›

Engineers designed an 'architected' reef that can mimic the wave-buffering effects of natural reefs while providing pockets for marine life. The sustainable and cost-saving structure could dissipate more than 95 percent of incoming wave energy using a small fraction of the material normally needed. Read more ›

Researchers have found that approved drugs that were originally shown to normalize blood vessels surrounding tumors (to improve drug delivery to cancer cells) can enhance the delivery of anti-microbial medications to kill tuberculosis bacteria residing in the lungs. Read more ›

Astronomers have found that a previously quiet black hole, which sits at the center of a galaxy about 800 million light years away, has suddenly erupted, giving off plumes of gas every 8.5 days before settling back to its normal, quiet state. Read more ›
