Researchers at the Texas A&M School of Veterinary Medicine and Biomedical Sciences (VMBS) have discovered that parents who struggle with alcohol use disorders can pass along symptoms of early aging to their children, affecting them well into adulthood.  These accelerated aging effects — including high cholesterol, heart problems, arthritis, and early onset dementia — can be passed down from either mom or dad individually, but they become worse when both parents have an issue with alcohol abuse, especially in male offspring. “Scientists have wondered what causes children who grow up in homes where there is alcohol ...

An activity pattern in certain genes responsible for building proteins known as spleen tyrosine kinases can predict which melanoma patients are likely to have severe side effects from immunotherapy designed to treat the most deadly skin cancer, a new study shows. Led by researchers at NYU Langone Health and its Perlmutter Cancer Center, the latest experiments focused on checkpoint inhibitors, drugs that have in the last decade become a mainstay of treating melanoma. This form of skin cancer kills nearly 10,000 Americans annually. The drugs work by blocking molecules ...

WASHINGTON — Researchers have shown that a fluorescence detection system that doesn’t contain any lenses can provide highly sensitive detection of deadly microorganisms in drinking water. With further development, the new approach could provide a low-cost and easy-to-use way to monitor water quality in resource-limited settings such as developing countries or areas affected by disasters. It could also be useful when water safety results are needed quickly, such as for swimming events, a concern highlighted during the Paris Olympics. “In developing countries, unsafe water sources ...

For decades, researchers have worked to develop therapies that can prime the immune system to recognize and attack proteins on the surface of tumor cells. However, success has been limited due to the technological challenge of engineering therapies that provide specific enough “training” to the immune system to identify a given patient’s neoantigens. Now, investigators from Massachusetts General Hospital (MGH), a founding member of the Mass General Brigham healthcare system, have evaluated an ...

WASHINGTON—Women with the common reproductive and metabolic condition polycystic ovary syndrome (PCOS) face a greater risk of developing bulimia, binge eating disorder and disordered eating, according to new research published in The Journal of Clinical Endocrinology & Metabolism. PCOS affects roughly one in eight women. Women who have the condition face an increased risk of developing metabolic problems such as diabetes, reproductive issues such as infertility, and psychological issues including anxiety and depression.

Nationally, falls remain the leading cause of both fatal and non-fatal injuries in older adults and are the leading cause of traumatic brain injury. In 2021, falls led to the deaths of 36,500 older adults in the United States and 3,805 older Floridians. While some studies have hypothesized that alcohol use contributed to these outcomes, there are few studies which have examined this issue.  As such, little is known about the association between the frequency of alcohol use and the severity of injuries sustained after a fall in older adults. A study by Florida Atlantic University’s Schmidt College of Medicine and collaborators, is one of the first to examine the relationship ...

As our climate changes and soil salinity increases in many agricultural areas, finding crops that can thrive in these challenging conditions is crucial. Cultivated tomatoes, while delicious, often struggle in salty soils. Their wild cousins, however, have evolved to survive in diverse and often harsh environments. A recent study delved into the genetic treasure trove of wild tomatoes to uncover secrets of salt tolerance that could be used to develop resilient crop varieties. A team of researchers focused on Solanum pimpinellifolium, the closest wild relative of our beloved cultivated tomato. These tiny, ...

Climate change is one of the most significant environmental challenges of present times, leading to extreme weather events, including droughts, forest fires, and floods. The primary driver for climate change is the release of greenhouse gases into the atmosphere due to human activities, which trap heat and raise Earth’s temperature. Aerosols (such as particulate matter, PM2.5) not only affect public health but also influence the Earth's climate by absorbing and scattering sunlight and altering cloud properties. Although future climate change predictions are being reported, it is possible that the impacts of climate change could be more severe than predicted. ...

According to the attention-based view, a firm’s actions and growth performance are directly influenced by its attentional allocation to specific issues. The consequences of organizational attention are reflected in the firm’s strategic decision-making and adaptability. However, existing literature is limited in its exploration of how a firm’s attentional uniqueness impacts its behavior and performance. Notably, attentional uniqueness refers to how the firm’s attentional allocation diverges from competitors in the same industry. To address the above-mentioned knowledge gap, Associate Professor Takumi ...

The deoxyribonucleic acid or DNA, the molecular system that carries the genetic information of living organisms, can transcribe and amplify information using its two helical strands. Creating such artificial molecular systems that match or surpass DNA in functionality is of great interest to scientists. Double-helical foldamers are one such molecular system.   Helical foldamers are a class of artificial molecules that fold into well-defined helical structures like helices found in proteins and nucleic acids. They have garnered considerable attention as stimuli-responsive switchable molecules, tuneable chiral materials, and cooperative supramolecular systems due to their chiral and ...

A saliva test can more accurately indicate the severity of recurrent respiratory infections in children than the standard blood test. If saliva contains too few broadly protective antibodies, a child is more likely to suffer from pneumonia episodes. This is reported by researchers from Radboudumc Amalia Children's Hospital and UMC Utrecht Wilhelmina Children's Hospital in the European Respiratory Journal. Saliva testing provides valuable information for treatment and is more comfortable for children.  About ...
