Investments in mitigating climate change in many cases benefit future generations more than those alive today. However, initial costs must be borne by those living now, so many climate mitigation policies rely on some level of intergenerational altruism for support. To investigate the strength and shape of intergenerational altruism, Gustav Agneman and colleagues asked Swedish study participants to engage in an experimental task in which they allocated fictional resources across generations, after being told how many descendants they might be expected to have in the next 250 years.  On average, participants allocated most of the resources to the present generation, and fewer and ...

The pursuit of carbon neutrality drives the exploration of clean energy sources, with hydrogen fuel cells emerging as a promising avenue. In these cells, hydrogen undergoes an electrochemical reaction with oxygen to produce electricity and water. Also, the reverse of this process, called electrolysis, can be used to split the abundantly available water to produce hydrogen and oxygen. These two technologies can work in tandem to provide a clean and renewable source of energy. A pivotal element in these two technologies is the platinum (Pt) electrode. Hydrogen fuel cells consist of two electrodes: an anode and a cathode, with an ...

Fukuoka, Japan - Researchers at Kyushu University have developed and validated a machine-learning model that can accurately evaluate the density of surviving tumor cells after treatment in pathological images of osteosarcoma—the most prevalent malignant bone tumor. The model can assess how individual tumor cells respond to treatment and can predict overall patient prognosis more reliably than conventional methods. Surgery and chemotherapy have significantly improved the outcomes of patients with localized osteosarcoma. However, patients with advanced metastatic disease (the stage where cancerous cells have spread to distant tissues) have a low survival rate. ...

All-solid-state lithium-ion (Li-ion) batteries with solid electrolytes are non-flammable and have higher energy density and transference numbers than those with liquid electrolytes. They are expected to take a share of the market for conventional liquid electrolyte Li-ion batteries, such as electric vehicles. However, despite these advantages, solid electrolytes have lower Li-ion conductivity and pose challenges in achieving adequate electrode-solid electrolyte contact. While sulfide-based solid electrolytes are conductive, they react with moisture to form toxic hydrogen disulfide. Therefore, there's ...

A new study found that during the pandemic pediatric emergency departments (EDs) saw more children and adolescents who needed a psychiatric admission, as well as an increase in severe conditions, such as bipolar disorder, schizophrenia and substance use disorders. The higher demand for a psychiatric inpatient bed often exceeded availability, resulting in over 12-hour stays in the ED awaiting admission for nearly 20 percent of children with mental health emergencies in 2022, up from 7 percent before the pandemic. Findings were published in Academic Emergency Medicine. “Our data shows that pediatric emergency departments saw more severe mental health presentations during the pandemic, ...

We’ve all been there: staring at a math test with a problem that seems impossible to solve. What if finding the solution to a problem took almost a century? For mathematicians who dabble in Ramsey theory, this is very much the case. In fact, little progress had been made in solving Ramsey problems since the 1930s. Now, University of California San Diego researchers Jacques Verstraete and Sam Mattheus have found the answer to r(4,t), a longstanding Ramsey problem that has perplexed ...

Chickens are one of the most economically important animals in the world today. However, the story of their origins and dispersal across the ancient world is still poorly understood. In fact, new archaeological techniques have recently led to the recognition that many finds of bones previously thought to represent early chickens in fact belonged to wild birds. Now, in a new publication, an international team of archaeologists, historians, and biomolecular scientists present the earliest clear evidence for the raising of chickens for egg production, and argue that the loss of seasonal egg laying was the main driver for the dispersal of domestic chickens across Eurasia and northeast Africa.  Using ...

Association in-between features has been demonstrated to improve the representation ability of data.  However, the original association data reconstruction method may face two issues: the dimension of reconstructed data is undoubtedly highly than that of original data, and adopted association measure method does not well balance effectiveness and efficiency. To solve the problems, a research team led by Yuhua QIAN published their new research on 12 Mar 2024 in Frontiers of ...

A recent collaborative study has discovered rare variants in the YKT6 gene as the cause of a new neurological disorder characterized by developmental delays along with severe progressive liver disease and a potential risk for liver cancer. The study, published in Genetics in Medicine, was led by Dr. Hugo Bellen, Distinguished Service Professor at Baylor College of Medicine and Principal Investigator at the Jan and Dan Duncan Neurological Research Institute (Duncan NRI) at Texas Children’s Hospital, and Dr. Wendy Chung, the Chief of the Department of Pediatrics at Boston Children’s ...

Australia could soon see megadroughts that last for more than 20 years, according to new modelling from The Australian National University (ANU) and the ARC Centre of Excellence for Climate Extremes. The researchers’ bleak findings are before factoring in human impact on the climate since the Industrial Revolution. The ANU-led team also found that 20th century droughts in southwestern and eastern Australia, including the Murray-Darling Basin, were longer on average compared to pre-industrial times. According to the scientists, the findings paint a worrying picture of future droughts in Australia that are far worse than anything in recent experience. Megadroughts are exceptionally ...

Jens Dilling has been named associate laboratory director for the Neutron Sciences Directorate, or NScD, at the Department of Energy’s Oak Ridge National Laboratory, effective April 1. “ORNL pioneered neutron scattering in the 1940s, developing a new technique that enables scientists to explore and create new materials, batteries and more,” ORNL Director Stephen Streiffer said. “Today, ORNL remains at the forefront of this science, and Jens will play a critical role in ensuring the nation's ...

Researchers at University of California San Diego School of Medicine have been awarded two new grants by the National Institutes of Health (NIH), totaling $6.7 million, to develop and clinically test technologies that can noninvasively examine and quantify immune cells found in tumors. These immune cells, called macrophages, are involved in the body’s normal inflammatory responses, but they also make up a significant portion of solid tumors. The density of macrophages in a tumor can affect how it responds to treatment, so the ability to count them noninvasively could help doctors decide which therapies ...

DARIEN, IL – The risk of increased health care utilization among children with a chronic medical condition is higher for those who also have a sleep disorder, according to a new study that examined Medicaid claims data. The study found that among children who had a chronic medical condition, those who also had a diagnosed sleep disorder were nearly two times more likely to have increased health care utilization (odds ratio = 1.83) than those who had no sleep disorder. The most common sleep disorder diagnosis was sleep-disordered breathing, which was present in 1,796 children. ...

For Tom Maccarone, the universe really is his laboratory. “I am drawn to the idea of things going on where there are conditions you have little or no hope of reproducing in a lab,” said Maccarone, a professor in the Department of Physics and Astronomy at Texas Tech University. “It gives you a way to do the most exotic physics experiments without having to build a giant laboratory. I am also drawn to problems where we still don’t really know anything.” Maccarone recently enjoyed the best of both ...

Mental health issues during pregnancy or the first year of parenthood have a much greater chance of getting detected and treated now than just over a decade ago, a trio of new studies suggests. But the rise in diagnosis and care hasn’t happened equally across different groups and states, leaving some pregnant or postpartum individuals more likely to suffer through treatable symptoms that can put themselves and their newborn at risk. In general, the studies show rises in diagnoses of anxiety, depression and post-traumatic stress disorder ...

Pregnancy and childbirth can be significant stressors on mental health. Nearly one in eight people who have given birth develop postpartum depression, according to the Centers for Disease Control and Prevention. More than just the “baby blues,” postpartum depressive symptoms can lead to adverse outcomes for birthing people and families, and treatment requires effective screening, diagnosis and management. New research from the UNC Gillings School of Global Public Health and the Columbia University Mailman ...

For many, spring heralds fresh air and exercise on the golf course. But do players risk exposure to unsafe levels of pesticides used to beautify and maintain a golf course’s green grass? To find out, researchers asked volunteers to play 18 holes on a simulated course sprayed with common pesticides. They report the results in ACS Agricultural Science & Technology, saying there is likely limited cause for concern over toxic exposure from pesticide-treated turf. There are plenty of studies on pesticide exposure among people who tend ...

Scientists have been searching for the optimal coronavirus vaccine since the Covid-19 pandemic started. The mRNA vaccines developed through the federal government's "Operation Warp Speed" program were a massive innovation; however, annually updating those boosters for specific SARS-CoV-2 variants is inefficient for scientists and patients. SARS-CoV-2 is just one member of the Sarbecovirus (SARS Betacoronavirus) subfamily (others  include SARS-CoV-1, which caused the 2002 SARS outbreak, as well as other viruses circulating in bats that could cause future pandemics). Researchers at the Georgia Institute of ...

ROCHESTER, Minn. — Mayo Clinic scientists have developed an immunotherapy strategy that potentially lays the groundwork for treating a spectrum of autoimmune diseases.  The new technique, detailed in a preclinical study published in Nature Biomedical Engineering, involves combining chimeric antigen receptors (CAR) with mesenchymal stromal cells (MSC), resulting in engineered stem cells known as CAR-MSCs.  “The pioneering approach shows potential in targeting inflammatory disease sites more precisely and improving immunosuppression and healing outcomes,” says Saad Kenderian, M.B., ...

An enormous meteor spelled doom for most dinosaurs 65 million years ago. But not all. In the aftermath of the extinction event, birds — technically dinosaurs themselves — flourished.  Scientists have spent centuries trying to organize and sort some 10,000 species of birds into one clear family tree to understand how the last surviving dinosaurs filled the skies. Cheap DNA sequencing should have made this simple, as it has for countless other species. But birds were prepared to deceive us. In a pair of new research papers ...
