If you’ve ever belly-flopped into a pool, then you know: water can be surprisingly hard if you hit it at the wrong angle. But many species of kingfishers dive headfirst into water to catch their fishy prey. In a new scientific study in the journal Communications Biology, researchers compared the DNA of 30 different kingfisher species to zero in on the genes that might help explain the birds’ diet and ability to dive without sustaining brain damage. The type of diving that kingfishers do-- what researchers call “plunge-diving”-- is an aeronautic feat. “It’s a high-speed dive from air to water, and it’s done by very few bird species,” says ...

Two different regions of the brain are critical to integrating semantic information while reading, which could shed more light on why people with aphasia have difficulty with semantics, according to new research from UTHealth Houston. The study, led by first author Elliot Murphy, PhD, postdoctoral research fellow in the Vivian L. Smith Department of Neurosurgery with McGovern Medical School at UTHealth Houston, and senior author Nitin Tandon, MD, professor and chair ad interim of the department in the medical school, was published today in Nature Communications. Language depends largely on the integration of vocabulary across multiple words ...

It's viable to produce low-cost, lightweight solar panels that can generate energy in space, according to new research from the Universities of Surrey and Swansea.  The first study of its kind followed a satellite over six years, observing how the panels generated power and weathered solar radiation over 30,000 orbits.  The findings could pave the way for commercially viable solar farms in space. Professor Craig Underwood, Emeritus Professor of Spacecraft Engineering at the Surrey Space Centre at the University of Surrey, said:  “We are very pleased that a mission designed to last one year is still working after six. These detailed data ...

Bacterial diversity in the gut plays an important role in human health. The crucial question, however, is where are the sources of this diversity? It is known that an important part of the maternal microbiome is transferred to the baby at birth, and the same happens during the breastfeeding period via breast milk. Further sources were yet to be discovered. However, a team led by Wisnu Adi Wicaksono and Gabriele Berg from the Institute of Environmental Biotechnology at Graz University of Technology (TU Graz) has now succeeded in proving that plant microorganisms from fruit and vegetables contribute to the human microbiome. They report this in a study published in ...

Patients with a dysfunctional aortic heart valve who received a new, prosthetic valve through a minimally invasive procedure had similar outcomes at five years as those who underwent open-heart surgery, a new study shows. The international multicenter study, with key contributions by the Cedars-Sinai heart team and published in The New England Journal of Medicine, offers a more complete picture to the ongoing dialogue comparing the minimally invasive heart procedure—called transcatheter aortic valve replacement, or TAVR—to open-heart surgery. “Our data at five years validate that TAVR is a good alternative to open-heart surgery in younger patients with aortic ...

BLOOMINGTON, Ind. – Using anonymized smartphone data from nearly 10,000 police officers in 21 large U.S. cities, research from Indiana University finds officers on patrol spend more time in predominantly Black and Hispanic neighborhoods. “Research on policing has focused on documented actions such as stops and arrests – less is known about patrols and presence,” said Kate Christensen, assistant professor of marketing at the IU Kelley School of Business. “Police have discretion in deciding where law enforcement is provided within America’s cities,” she said. “Where police officers are located matters, because it affects ...

A novel device developed by researchers from Tokyo Institute of Technology, Tokyo Medical and Dental University, and Chiba University in a new study utilizes ions and an electric field to effectively capture infectious droplets and aerosols, while letting light and sound pass through to allow communication. The innovation is significant in the wake of the COVID-19 pandemic, since it shows promise in preventing airborne infection while facilitating communication. Airborne infections, such as H1N1 influenza, SARS, and COVID-19, are spread by aerosols ...

Remember when your parents used to say, “Eat your greens, they are good for you”? Well, they were really onto something. Several studies have shown that higher intakes of cruciferous vegetables like broccoli, one of the most widely consumed vegetables in the United States, are associated with reduced risks of diseases such as diabetes and cancer, thanks to their organosulfur compounds, such as glucosinolates and isothiocyanates that exhibit a broad spectrum of bioactivities including antioxidant activity. However, few studies have focused on ...

A lack of clarity around sustainability reporting is allowing ASX-listed companies to retrospectively alter figures, ensuring CEO bonus pay tied to these metrics is realised, new research suggests.  Sustainability reports serve as critical tools for investors, regulators and other stakeholders to gauge a company's environmental, social, and governance (ESG) performance. They highlight issues such as environmental pollution and worker safety that might otherwise be overlooked. Close to 90% of ASX top 200 companies provide detailed ESG information. Many of these ...

Layered lithium cobalt oxide, a key component of lithium-ion batteries, has been synthesized at temperatures as low as 300°C and durations as short as 30 minutes. Lithium ion batteries (LIB) are the most commonly used type of battery in consumer electronics and electric vehicles. Lithium cobalt oxide (LiCoO2) is the compound used for the cathode in LIB for handheld electronics. Traditionally, the synthesis of this compound requires temperatures over 800°C and takes 10 to 20 hours to complete. A team of researchers at Hokkaido University and Kobe University, led by Professor Masaki Matsui at Hokkaido University’s Faculty of Science, have developed a new method to ...

Harnessing new advances in genomic surveillance technology could help detect the rise of deadly ‘superbugs’ and slow their evolution and spread, improving global health outcomes, a new Australian study suggests. Antimicrobial resistance occurs when bacteria, viruses, fungi and parasites change over time and no longer respond to the medicines and chemicals we use to kill them. These ‘superbugs’ make infections harder to treat and increase the risk of disease spread, severe illness and death. Without significant intervention, global annual deaths involving antimicrobial resistance are estimated ...

AURORA, Colorado (October 23, 2023) - The burning of sugarcane and rice husks may be releasing a toxicant causing a mysterious kidney disease in agricultural workers, according to a paper out today in the American Journal of Kidney Diseases. An ongoing epidemic of chronic kidney disease has been observed among manual laborers in hot agricultural communities throughout the world, including along the Pacific coast of Central America, India and Sri Lanka. While heat stress and climate change have contributed to this epidemic, researchers have identified tiny silica particles released from sugarcane ash that can be inhaled or ingested through contaminated drinking water that cause ...

A research team from the UC Davis Comprehensive Cancer Center has identified a crucial epitope (a protein section that can activate the larger protein) on the CD95 receptor that can cause cells to die. This new ability to trigger programmed cell death could open the door for improved cancer treatments. The findings were published Oct. 14 in the Nature journal Cell Death & Differentiation. CD95 receptors, also known as Fas, are called death receptors. These protein receptors reside on cell membranes. When activated, ...

https://doi.org/10.1016/j.bsheal.2023.08.005   During severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, activated macrophages, dendritic cells, neutrophils, and natural killer cells are the first defense against infection. These immune effectors trap and ingest the virus, kill infected epithelial cells, or produce anti-viral cytokines. Evidence suggests that aging, obesity, and mental illness can lead to weakened innate immunity and, thus, are all associated with elevated infection and severe disease progression of coronavirus disease 2019 (COVID-19). ...

https://doi.org/10.1016/j.bsheal.2023.08.004   Data on the viral rebound and safety of nirmatrelvir/ritonavir in lung transplant (LTx) recipients are limited. The study prospectively followed four LTx recipients. Clinical characteristics, viral RNA dynamic in throat swabs, and tacrolimus blood concentration were monitored regularly. All four LTx recipients, aged 35–74 years, were not vaccinated against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). They got coronavirus disease 2019 (COVID-19) after ...

TORONTO, October 23, 2023 –This year, Canada saw the worst wildfire season in its history, with fires destroying homes, displacing thousands of residents, and burning the largest area since contemporary records began in 1983. Much of this damage to communities could be reduced with better wildfire preparedness – but wildland urban interface (WUI) communities often face significant barriers in implementing these improvements, according to a study by York University’s Disaster and Emergency Management researchers. According to the study, Determinants of residential wildfire mitigation uptake: A ...

In 2021, a team of University of Arizona astronomers suggested that a recently discovered near-Earth asteroid, Kamo`oalewa, could be a chunk of the moon. Two years after the striking discovery, another UArizona research group has found that a rare pathway could have enabled this to happen. So far, only distant asteroids from beyond the orbit of Mars have been considered a source of near-Earth asteroids, said Renu Malhotra, Regents Professor of Planetary Sciences and a senior author on the paper. "We are now establishing that the moon is a more likely source ...

A new study by University of Iowa researchers finds that rare lung cells known as pulmonary ionocytes facilitate the absorption of water and salt from the airway surface. This function is exactly the opposite of what was expected of these cells and may have implications for cystic fibrosis (CF) lung disease.   Five years ago, scientists reported the unexpected discovery that ionocytes—a cell type commonly found in fish gills and frog skin—are also present in the lining of human lungs and airways. These pulmonary ionocytes were particularly interesting to CF researchers because although they only account for about 1% of all the cells in the airway ...

Researchers at New Jersey Institute of Technology’s Center for Solar-Terrestrial Research (NJIT-CSTR) have captured the Oct. 14 solar eclipse in a way never seen before — recording the first radio images of an annular eclipse’s famous “ring of fire” effect. The eclipse was partially visible to much of the continental U.S. for several hours that Saturday, though the full “ring of fire” effect was only visible for less than five minutes, and only for those within its 125-mile-wide path of annularity. However, the new observations of the radio Sun’s eclipse — ...
