Promising new research suggests a total of just 4.5 minutes of vigorous activity that makes you huff and puff during daily tasks could reduce the risk of some cancers by up to 32 percent.  Published in JAMA Oncology and led by the University of Sydney, Australia, the study used data from wearable devices to track the daily activity of over 22,000 ‘non-exercisers’. Researchers then followed the group’s clinical health records for close to seven years to monitor for cancer. As few as four to five minutes of vigorous intermittent lifestyle physical activity or ‘VILPA’ was associated with a substantially lower cancer risk compared to those who undertook no ...

Two leading sequencing techniques are no longer at odds, thanks to an international effort led by scientists at University of California San Diego. In a study published July 27, 2023 in Nature Biotechnology, the researchers debuted a new reference database called Greengenes2, which makes it possible to compare and combine microbiome data derived from either 16S ribosomal RNA gene amplicon (16S) or shotgun metagenomics sequencing techniques.  “This is a significant moment in microbiome research, as we’ve effectively rescued over a decade’s worth of 16S data that might have otherwise become obsolete in the modern world ...

  There’s no doubt that Aussies love a good celebration. We’re all in when it comes to the weekend, and most of us can’t go past a Christmas celebration without a little bit of overindulging. But all this comes at a cost, and it’s taking a massive toll on our waistline.   Now, a world-first study from the University of South Australia exposes the real weight gains of everyday Australians, in a move to tackle overweight and obesity.   Funded by the NHMRC, and published in JAMA Open Network today, the study explored how weight changes across a 12-month period, finding that weight fluctuated throughout the year.   Specifically, ...

Chemotherapy and radiotherapy aim to destroy cancer cells by inducing DNA double-strand breaks – damage that, once inflicted, usually causes the cells to die. But damage to a cell’s genetic material also activates a signaling pathway called IKK/NF-κB that helps prevent cell death, thus limiting the success of these treatments in patients. NF-κB is a family of gene regulators that controls a wide variety of cellular processes – from immune responses to embryonic development – and is activated by the enzyme complex ...

Over the last decade, advances in 3D printing have unlocked new possibilities for bioengineers to build heart tissues and structures. Their goals include creating better in vitro platforms for discovering new therapeutics for heart disease, the leading cause of death in the United States, responsible for about one in every five deaths nationally, and using 3D-printed cardiac tissues to evaluate which treatments might work best in individual patients. A more distant aim is to fabricate implantable tissues that can heal or replace faulty or diseased structures inside a patient’s heart. In a paper published in Nature Materials, researchers ...

Dr. Raymond Chan's team from the Institute of Psychology of the Chinese Academy of Sciences and his collaborators have recently shown that amotivation and anhedonia, rather than expressive dysfunction, play a crucial role in determining the social functioning of schizophrenia patients. The study was published in Nature Mental Health. Negative symptoms refer to the loss of normal functioning, including anhedonia, avolition, alogia, asociality, and affective blunting, and have been shown to be the most important predictors ...

Conventional wisdom holds that storing fat around your belly puts you at increased risk for type 2 diabetes. But surprising new findings from the University of Virginia School of Medicine suggest that naturally occurring variations in our genes can lead some people to store fat at the waist but also protect them from diabetes. The unexpected discovery provides a more nuanced view of the role of obesity in diabetes and related health conditions. It also could pave the way for more personalized medicine – treatments tailored to the individual. ...

INDIANAPOLIS – Accessing neurologic care often presents physical, geographical and financial challenges to patients, many of whom face chronic and disabling conditions. With a nationwide scarcity of neurologists in the U.S., especially in rural areas, disparities in access to timely neurological assessment and treatment are not uncommon. Telehealth addresses access to care as well as other inequity issues. To meet the need for prompter care and to diminish disparity for rural veterans, the U.S. Department of Veterans’ Affairs (VA) National Teleneurology Program was funded in 2019 by the VA’s Office of Rural Health. The program is a patient-centered, ...

The global outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its new variants has created a need for effective disinfection technologies to protect against harmful pathogens. While vaccines offer some protection, their effectiveness against future variants is uncertain. Therefore, additional strategies are important during the pre-vaccine stage. UV irradiation has lately emerged as a safe, effective, and convenient strategy to inactivate and eliminate disease-causing micro-organisms. The wavelength range of 200-235 ...

Separation processes are essential in the purification and concentration of a target molecule during water purification, removal of pollutants, and heat pumping, accounting for 10–15% of global energy consumption. To make the separation processes more energy efficient, improvement in the design of porous materials is necessary. This could drastically reduce energy costs by about 40–70%. The primary approach to improving the separation performance is to precisely control the pore structure. In this regard, ...

Did you know rivers carry about 40 trillion metric tons of river water into the ocean every year? This meeting point, known as the estuary, holds great potential for electricity generation. Mixing the two types of water -- seawater and river water containing different salt concentrations -- releases a substantial amount of Gibbs free energy, which can be converted to electricity using semipermeable membranes. However, the performance of membranes has limited the economic viability of membrane-based approaches, leaving the vast potential of this naturally abundant energy source largely untapped. To overcome the challenges associated with the membranes, researchers have developed membrane-free ...

Roughly six million Black people moved away from the American South during the Great Migration between 1910 and 1970, hoping to escape racial violence and discrimination while pursuing economic and educational opportunities. Now, research has uncovered a link between this historic event with present-day inequalities and implicit biases. In a new Social Psychological and Personality Science article, researchers report that current implicit bias among White people at the county-level is associated with the proportion of Black residents living in that county during the Great Migration (circa 1930). The research supports the Bias ...
