Under the new leadership of Dr. Weston Porter, a VMBS professor in the Department of Veterinary Physiology and Pharmacology, the center will promote research in four areas of environmental health — climate ...

BIRMINGHAM, Ala. – Drosophila — commonly known as fruit flies — are a valuable model for human heart pathophysiology, including cardiac aging and cardiomyopathy. However, a choke point in evaluating fruit fly hearts is the need for human intervention to measure the heart at moments of its largest expansion or its greatest contraction, measurements that allow calculations of cardiac dynamics. Researchers at the University of Alabama at Birmingham now show a way to significantly cut the time needed ...

Key Takeaways More people are surviving cancer than ever before and living longer. This growing population of adult cancer survivors requires distinct survivorship services focused on long-term well-being. Survey study demonstrates the value of American College of Surgeons’ survivorship accreditation standards, though specialized services in fertility and sexual health are less accessible. CHICAGO — With the number of adult cancer survivors in the United States expected to reach 23 million by 2032,* the long-term needs of this ...

Summary Global warming as well as recent droughts and floods threaten large populations along the Nile Valley. Understanding how such a large river will respond to an invigorated hydrological cycle is therefore a pressing issue. Insights can be gained by studying past periods with wetter and warmer conditions, such as the North African Humid Period eleven to six thousand years ago. A research team of the German Research Centre for Geosciences GFZ, led by Cécile Blanchet, together with colleagues ...

A new study led by investigators from Mass Eye and Ear found that patients prescribed semaglutide (as Ozempic or Wegovy) for diabetes or weight loss had a higher risk of having a potentially blinding eye condition called NAION than similar patients who had not been prescribed these drugs. Notably, the study found people with diabetes who had been prescribed semaglutide by their physician and then filled the prescription were more than four times more likely to be diagnosed with NAION. Those who were overweight or had obesity and prescribed this drug were more than seven times more likely to get the diagnosis. The study, which ...

The ongoing opioid epidemic in the U.S. kills tens of thousands of people every year. Naloxone, sold under the brand name Narcan, has saved countless lives by reversing opioid overdoses. But new and more powerful opioids keep appearing, and first responders are finding it increasingly difficult to revive people who overdose. Now, researchers have found an approach that could extend naloxone’s lifesaving power, even in the face of ever-more-dangerous opioids. A team of researchers from Washington University School of Medicine in St. Louis, Stanford University and the University of Florida have identified potential ...

States with Highest COVID-19 Vaccination Rates Showed Steepest Decline in Pediatric Asthma Prevalence Study suggests COVID-19 vaccination might have broader benefits for children living with asthma WILMINGTON, Del. (July 3, 2024) — States with high rates of COVID-19 vaccination saw more pediatric asthma patients get a break from their symptoms, according to new research published today in JAMA Network Open by leaders from Nemours Children’s Health and Endeavor Health. “Asthma is one of the most common chronic illnesses among children in the United States, with about 4.7 million ...

Dexamethasone is one of the most important drugs in the treatment of severe COVID-19, but patients respond very differently to the therapy. Researchers at the German Center for Neurodegenerative Diseases (DZNE) and Charité – Universitätsmedizin Berlin have now discovered how the cortisone compound influences the impaired inflammatory response and which patients benefit from it. Their method uses so-called single-cell analyses and raises hopes for a precise prediction tool for other therapies and diseases as well. The findings have been published in the scientific journal Cell. It has long been puzzling why certain drugs work so well for some people and fail ...

In the decade since their discovery at Drexel University, the family of two-dimensional materials called MXenes has shown a great deal of promise for applications ranging from water desalination and energy storage to electromagnetic shielding and telecommunications, among others. While researchers have long speculated about the genesis of their versatility, a recent study led by Drexel and the University of California, Los Angeles, has provided the first clear look at the surface chemical structure foundational to MXenes’ capabilities. Using advanced imaging techniques, known as ...

A new way to map the spread and evolution of pathogens, and their responses to vaccines and antibiotics, will provide key insights to help predict and prevent future outbreaks. The approach combines a pathogen’s genomic data with human travel patterns, taken from anonymised mobile phone data. Researchers from the Wellcome Sanger Institute, University of the Witwatersrand and National Institute for Communicable Diseases in South Africa, the University of Cambridge, and partners across the Global Pneumococcal Sequencing project1, integrated genomic data from nearly 7,000 Streptococcus pneumoniae (pneumococcus) samples collected in South Africa with detailed ...

A key mechanism which detects when the brain needs an additional energy boost to support its activity has been identified in a study in mice and cells led by UCL scientists. The scientists say their findings, published in Nature, could inform new therapies to maintain brain health and longevity, as other studies have found that brain energy metabolism can become impaired late in life and contribute to cognitive decline and the development of neurodegenerative disease. Lead author Professor Alexander Gourine (UCL Neuroscience, ...

Bone remains found in a Tibetan cave 3,280 m above sea level indicate an ancient group of humans survived here for many millennia, according to a new study published in Nature.   The Denisovans are an extinct species of ancient human that lived at the same time and in the same places as Neanderthals and Homo sapiens. Only a handful Denisovan remains have ever been discovered by archaeologists. Little is known about the group, including when they became extinct, but evidence exists to ...

The more we discover about the natural world, the more we find that nature is the greatest engineer. Past research believed that liquids can only be transported in fixed direction on species with specific liquid communication properties and cannot switch the transport direction. Recently, The Hong Kong Polytechnic University (PolyU) researchers have shown that an African plant controls water movement in a previously unknown way – and this could inspire breakthroughs in a range of technologies in fluid dynamics and nature-inspired materials, including applications that require multistep and repeated reactions, such as microassays, medical ...

Fukuoka, Japan—The phenomenon known as El Niño can cause abnormal and extreme climate around the world due to it dramatically altering the normal flow of the atmosphere. In Japan, historical data has shown that El Niño years tend to lead to warmer winters. This case was exemplified recently with Japan’s warm 2023-2024 winter season. However, there have also been cases of cold winters in Japan during El Niño years, such as the one recorded in 2014-2015. Yet, it was unclear as to why this was occurring. Publishing in the Journal of Climate, ...

Norway wastes huge amounts of energy. Surplus heat produced by industry is hardly exploited at all. Researchers at the Norwegian University of Science and Technology (NTNU) have been looking at the possibilities for doing something about this. “Surplus heat from industrial processes is a huge resource,” says Kim Kristiansen. He has just completed his PhD on a technology that can harness some of the surplus heat that currently goes to waste. Almost all the heat generated by industrial processes is currently released directly into the air or the ocean, and we are not talking about small amounts. In Norway alone, industry produces ...

Bowel cancer cells have the ability to regulate their growth using a genetic on-off switch to maximise their chances of survival, a phenomenon that’s been observed for the first time by researchers at UCL and University Medical Center Utrecht. The number of genetic mutations in a cancer cell was previously thought to be purely down to chance. But a new study, published in Nature Genetics, has provided insights into how cancers navigate an “evolutionary balancing act”. The researchers found that mutations in DNA repair genes can be repeatedly created and repaired, acting as ‘genetic switches’ that take the brakes off a tumour’s growth ...

New experimental research shows that the combined effects of ocean warming and acidification could lead to a catastrophic decrease in embryonic shark survival by the year 2100. This research is also the first to demonstrate that monthly temperature variation plays a prominent role in shark embryo mortality. Oceanic warming and acidification are caused by greater concentrations of CO2 dissolving into marine environments, resulting in rising water temperatures and falling pH levels. “The embryos of egg-laying ...

France’s natural history collections contain nearly 6% of the world’s total natural specimens across multiple institutions, and the e-COL+ project aims to capture and reconstruct these specimens in 3D for easy access and 3D printing around the world. “I’m a researcher of vertebrate locomotion and vocalisation, so I produce a lot of CT scans and 3D models – and now I’m in charge of developing the museum’s own 3D digital collection,” ...

New research finds that artificial light at night (ALAN) attracts larval fish away from naturally lit habitats, while dramatically lowering their chances of survival in an “ecological trap”, with serious consequences for fish conservation and fishing stock management. “Light pollution is a huge ongoing subject with many aspects that are still not well understood by scientists,” says Mr Jules Schligler, a PhD student at CRIOBE Laboratory (Centre de Recherches Insulaires et Observatoire de l’Environnement) in Moorea, French Polynesia. ALAN is the product of human-related ...

A recent sociological study finds that most young adults surveyed reported feeling confused about their options when it comes to dating decisions. Preliminary analysis suggests that more than half of young people experience confusion about choosing life-partners, with women appearing to be more likely to report partner selection confusion than men. Due to the pervasiveness of social media and digital dating in everyday lives, humans are now exposed to many more potential mates than ever before, but the availability of popular dating apps ...
