Researchers are deploying the latest mapping techniques to identify the most important suburban habitat for North America’s largest woodpecker. University of Cincinnati doctoral student Ruijia Hu said wildlife habitat in congested places like southwest Ohio is becoming increasingly fragmented as forests give way to new construction. Eventually, this could spell trouble to an animal with specific habitat needs like Ohio’s pileated woodpecker. Pileated woodpeckers are crow-sized birds with colorful red crests and striking white facial stripes. They are found in forests from British Columbia to Florida. They have the ...

A new study by Cedars-Sinai investigators describes how ChatGPT, an artificial intelligence (AI) chatbot, may help improve health outcomes for patients with cirrhosis and liver cancer by providing easy-to-understand information about basic knowledge, lifestyle and treatments for these conditions.  The findings, published in the peer-reviewed journal Clinical and Molecular Hepatology, highlights the AI system’s potential to play a role in clinical practice. “Patients with cirrhosis and/or liver cancer and their caregivers often have unmet needs and insufficient knowledge about managing and preventing complications of their disease,” ...

Twenty to 50 per cent of all critically ill patients contract potentially deadly infections during their stay in the intensive care unit or in hospital after being in the ICU – markedly increasing the risk of death. “Despite the use of antibiotics, hospital-acquired infections are a major clinical problem that persists to be a huge issue for which we don’t have good solutions,” says Dr. Braedon McDonald, MD, PhD, an intensive care physician at the Foothills Medical Centre (FMC) and assistant professor at the ...

BENTLEY UNIVERSITY The financial terms of biotechnology licenses from academic institutions are significantly less favorable than those of comparable licenses between commercial firms according to a new study from Bentley University’s Center for Integration of Science and Industry. The study, published in the journal PLOS ONE, shows that the royalties and payments to academic institutions are significantly lower than those to commercial firms for similar licenses and products at the same stages of development.  The article, titled “Comparing the economic terms of biotechnology licenses from academic institutions with those ...

As Earth’s population grows, the demands of modern lifestyles place mounting strain on the global environment. Proposed solutions to preserve and promote planetary sustainability can sometimes prove more harmful than helpful. However, technologies that harness natural processes could be more successful. Such technologies are the focus of the latest issue of the open access journal PLOS Biology, which features a special collection publishing March 31st of papers highlighting biology-based solutions that could be applied to reduce carbon dioxide emissions, eliminate non-degradable plastics, produce food or energy ...

Can an individual’s social status have an impact on their level of stress? Researchers at Tulane University put that question to the test and believe that social rank, particularly in females, does indeed affect the stress response. In a study published in Current Biology, Tulane psychology professor Jonathan Fadok, PhD, and postdoctoral researcher Lydia Smith-Osborne looked at two forms of psychosocial stress — social isolation and social instability — and how they manifest themselves based on social rank. They conducted their research on adult female mice, putting them in pairs and allowing them to form a stable ...

Long thought of as “brain glue,” the star-shaped cells called astrocytes—members of a family of cells found in the central nervous system called glial that help regulate blood flow, synaptic activity, keep neurons healthy, and play an important role in breathing. Despite this growing appreciation for astrocytes, much remains unknown about the role these cells play in helping neurons and the brain process information. “We believe astrocytes can add a new dimension to our understanding of how external and internal information is merged in the ...

UNIVERSITY PARK, Pa. — In the early 2000s, scientists observed lightning discharge producing X-rays comprising high energy photons — the same type used for medical imaging. Researchers could recreate this phenomenon in the lab, but they could not fully explain how and why lightning produced X-rays. Now, two decades later, a Penn State-led team has discovered a new physical mechanism explaining naturally occurring X-rays associated with lightning activity in the Earth’s atmosphere.  They published their ...

East Hanover, NJ – March 31, 2023 – Since the pandemic, gains in the labor market have been slower to materialize for black/African American people with disabilities compared to their white counterparts, according to experts speaking last Friday during the nTIDE Deeper Dive Lunch & Learn Webinar. They discussed potential factors underlying why the disability employment gap is wider among members of the black/African American population when compared to the white population and how to integrate measures to effect change. Using data from the U.S. Bureau of Labor Statistics (BLS) for persons ages 16-64, the monthly employment-to-population ratio averaged ...

Antibiotic resistance is a global health threat. In 2019 alone, an estimated 1.3 million deaths were attributed to antibiotic resistant bacterial infections worldwide. Looking to contribute a solution to this growing problem, researchers at Baylor College of Medicine have been studying the process that drives antibiotic resistance at the molecular level. They report in the journal Molecular Cell crucial and surprising first steps that promote resistance to ciprofloxacin, or cipro for short, one of the most commonly prescribed antibiotics. The findings point at potential ...

HUNTINGTON, W.Va. – A new study led by Marshall University researchers focuses on a novel mechanism of the body’s regulation of salt balance. The kidney plays a central role in the body’s ability to maintain an appropriate sodium balance, which is critical for the determination of blood pressure. Disorders of sodium balance contribute to the development and progression of many common diseases, including hypertension, heart disease and stroke.  Na/K-ATPase (NKA) is the enzymatic machinery that drives absorption of sodium along the renal proximal tubule. As ...

UNIVERSITY PARK, Pa. — Just as a tight core is a component of good physical fitness for humans, helping to stabilize our bodies, mutations that tightened the core of the SARS-CoV-2 spike protein in new variants may have increased the virus’s fitness. New research led by Penn State reveals that the stem region of the spike protein became progressively tighter over time, and the team thinks this likely improved the virus’s ability to transmit through nasal droplets and infect host cells once in the body. The team said the stem region of the protein that emerged in the most recent Omicron variants is as rigid as it can get, which could ...

A rare and nevertheless formidable event in the landscape of epilepsies, New-Onset Refractory Status Epilepticus (NORSE) is a form of prolonged seizure in which the neurons of the epileptic focus endure a continuous discharge of neurotransmitters. It is a medical emergency requiring intensive care management. Indeed, it can cause significant long-term neurological sequelae and is associated with an average mortality rate of 12% in children and 16 to 27% in adults. NORSE can occur in response to an infection or tumor development. However, its origin remains unknown in half of the affected patients despite extensive clinical and biological ...

The human body contains more than 30 trillion cells. Until recently, the sheer number of cells in the organism meant that approaches to understanding human diseases and developmental processes based on the analysis of single cells were a futuristic vision. The development of new sequencing methods is currently revolutionising our understanding of cellular heterogeneity. These technologies can detect rare or even new cell types by extracting and sequencing the genetic information from the cells based on ribonucleic acid chains. In cooperation ...

Combined long-term survival results from nonrandomized phase II trial NRG Oncology RTOG 0630 and the ancillary analysis of the combined NRG-RTOG 0630/9514 trials indicate that pathologic complete response (pCR) is associated with improved survival outcomes for patients with localized soft tissue sarcoma (STS) who receive preoperative chemoradiotherapy or radiotherapy. This data suggests that pCR can be used as a prognostic factor for clinical outcomes in future STS research. These results were recently published in the JAMA Oncology. NRG-RTOG 0630 and 9514 both evaluated STS patients who were receiving either preoperative image-guided radiotherapy (IGRT; 0630) or neoadjuvant ...

Journal Comparison Service (JSC) is an initiative by cOAlition S aimed to improve ...

Some species of mussels can see. Scallops, for example, have up to 200 eyes that help them detect predators such as an approaching starfish. However, the eyes of scallops differ significantly from the human eye. While in our eyes the combination of cornea and lens creates an image on the retina, in scallop eyes light is focused by a hemispherical mirror. Optical imaging with lenses or mirrors Creating images with mirrors instead of lenses is especially common in astronomical telescopes, in order to capture as much light as possible from planets, stars and galaxies. In the Schmidt telescope developed in the 1930s by Bernhard Schmidt (1879-1935) and still in use in many observatories today, ...

Lehigh Engineering researcher Arup SenGupta has developed a novel way to capture carbon dioxide from the air and store it in the “infinite sink” of the ocean. The approach uses an innovative copper-containing polymeric filter and essentially converts CO2 into sodium bicarbonate (aka baking soda) that can be released harmlessly into the ocean. This new hybrid material, or filter, is called DeCarbonHIX (i.e., decarbonization through hybrid ion exchange material), and is described in a paper recently published in the journal Science Advances.  The research, which demonstrated a 300 percent increase in the amount of carbon captured ...

A groundbreaking technique developed by researchers affiliated with the USC Michelson Center for Convergent Bioscience presents a new way of gathering and organizing highly detailed information about organic tissues in record time. The methods could someday be used to rapidly process tissue biopsies in cancer care or detecting bacteria in food processing plants. Tissues emit signals, or intrinsic fields, that while detectable are very weak and hard to differentiate. The technique, detailed in a pair of papers published in Nature Methods ...

New University of British Columbia research is challenging a longstanding assumption that a baby’s gut microbiome is primarily shaped by their mother’s vaginal microbiome, while shedding new light on the factors that do influence its development. When babies are born, their gut is a nearly sterile environment. But that quickly changes as the infant’s digestive tract becomes home to trillions of microbial cells throughout their early development. This gut microbiome is an important part of overall health and alterations early in life have been associated with negative health outcomes later on, including asthma and obesity. It has ...
