MADISON, Wis., - Carbon dioxide removal (CDR) technologies that could be critical tools to combat climate change have developed in line with other technologies from the last century. However, according to new studies led by Gregory Nemet, a professor at the University of Wisconsin–Madison, these technologies need to develop faster to meet policy targets aimed at limiting global warming. As policymakers, researchers and climate activists from around the world prepare to meet for the UN Climate Change Conference beginning on ...

The program exposes undergraduate students to opportunities in particle and nuclear physics, which offer key components in many diverse careers, such as nuclear medicine, radiation therapy, archaeology, precision management and astrophysics. UTA’s Nuclear Research Experiences for Minority Students (NREMST) started in 2021 with the goal of immersing students from historically underrepresented populations in nuclear physics. “We know that many students ...

A major new research project will explore the impact of transformational changes to mental health treatment in South America.   Community-based care for people with psychosocial disabilities began in the region in the 1960s and 1970s, when a minority of people were moved from large and isolated psychiatric hospitals to  residential alternatives in the community.   This policy was promoted by the World Health Organization and the Pan America Health Organization and is considered a defining element of the modernisation of mental health systems. But in current analysis of this process the ethical, social and political tensions associated ...

Scientists have discovered that bacteria can create something like memories about when to form strategies that can cause dangerous infections in people, such as resistance to antibiotics and bacterial swarms when millions of bacteria come together on a single surface. The discovery — which has potential applications for preventing and combatting bacterial infections and addressing antibiotic-resistant bacteria — relates to a common chemical element bacterial cells can use to form and pass along these memories to their progeny over later generations. Researchers ...

CORVALLIS, Ore. – Forest modeling by Oregon State University scientists shows that a site’s productivity – an indicator of how fast trees grow and how much biomass they accumulate – is the main factor that determines which time period between timber harvests allows for maximum above-ground carbon sequestration. The findings, published in the journal Forests, are important for Pacific Northwest forest managers seeking to strike an optimal balance between harvesting and carbon sequestration, an important tool in the fight against climate change. The study by Catherine Carlisle, Temesgen Hailemariam ...

People who speak two languages may be better at shifting their attention from one thing to another compared to those who speak one, according to a study published this month in the journal Bilingualism: Language and Cognition.  The study examined differences between bilingual and monolingual individuals when it comes to attentional control and ignoring information that isn’t important at the time, said its authors Grace deMeurisse, a University of Florida Ph.D. candidate studying linguistics, and Edith Kaan, ...

(MEMPHIS, Tenn. – November 21, 2023) Findings from St. Jude Children’s Research Hospital are moving the field of cancer immunotherapy one step closer to treating brain and solid tumors. Scientists at St. Jude validated a cellular immunotherapy target called 78-kDa glucose-regulated protein (GRP78) in proof-of-principle experiments. The group also discovered a resistance mechanism whereby some tumors trick the cancer-killing immune cells into expressing GRP78, thereby turning off the immune cells or causing them to be killed, too. The research, which has implications for developing immunotherapy for the broad range of difficult-to-treat ...

TORONTO, Nov. 21, 2023 – Faced with images that break the expected pattern, like a do not enter sign where a stop sign is expected, how does the brain react and learn compared to being shown images which match what was predicted? That was the question a team, including York University, set out to answer. A long-standing theory suggests the brain learns a predictive model of the world and its internal predictions are updated when incoming sensory data proves them wrong. However, what the researchers found surprised them, says York Faculty of Science Associate Professor Joel Zylberberg, co-corresponding author of the newly published paper. “Testing ...

A new analysis sheds light on the molecular processes involved when a carnivorous species of fungus known as Arthrobotrys oligospora senses, traps and consumes a worm. Hung-Che Lin of Academia Sinica in Taipei, Taiwan, and colleagues present these findings November 21st in the open access journal PLOS Biology. A. oligospora usually derives its nutrients from decaying organic matter, but starvation and the presence of nearby worms can prompt it to form traps to capture and consume worms. A. oligospora is just one of many species of fungi that can trap and eat very small animals. Prior research has illuminated some of the biology behind this ...

In Germany, taxing sugar-sweetened beverages could prevent or postpone cases of type 2 diabetes, extend healthy lifespans and save up to €16.0 billion in societal costs over the next 20 years, according to a new study led by Karl Emmert-Fees of the Technical University of Munich, published November 21st in the open access journal PLOS Medicine. The World Health Organization has recommended that governments worldwide lessen the social and economic burden of cardiometabolic disease by taxing sugar-sweetened beverages. These taxes either reduce consumption by increasing the price, such as the one peso per liter ...

A simulation study conducted by a team from the Technical University of Munich (TUM) demonstrates that a soft drink tax in Germany would have significant positive effects. In all of the simulated variants evaluated, less sugar was consumed and the rate of illness dropped. This would be a way to reduce costs to the national economy and alleviate the burden on the health care system. There is, however, a difference between taxes aimed at reducing soft drink consumption and taxes aimed at bringing about changes in product formulation. Sugary beverages increase the risk of obesity and illnesses such as diabetes. Several countries have therefore introduced taxes on soft drinks. In Germany ...

An analysis of 5.8 million authors across all scientific disciplines shows that the gender gap is closing, but there is still a long distance to go. The new research by John Ioannidis of the Meta-Research Innovation Center at Stanford (METRICs) at Stanford University, US, and colleagues, publishes November 21st in the open access journal PLOS Biology. There is a strong gender gap in science which manifests itself in many ways. One of the most prominent ones is the relative representation of men and women among the scientists whose work receive the most attention in the ...

A set of fossils recovered in Rio Grande do Sul, Brazil’s southernmost state, has brought an extra layer of complexity to the study of the evolutionary history of silesaurids, a family of dinosauriforms (dinosaurs and their close relatives) that lived in the Triassic period between 247 million and 208 million years ago. In an article published in the Journal of Vertebrate Paleontology, researchers affiliated with institutions in Brazil and the United States show that even with the new fossil assemblage ...

Tuesday, Nov. 21, 2023, CLEVELAND: Cleveland Clinic researchers analyzed genes and brain tissue of patients with Alzheimer’s and found that differences in brain immunometabolism – the interactions between the immune system and the ways cells create energy – may contribute to women’s increased risk for the disease and its severity.  The findings, published in Alzheimer’s and Dementia, offer important insight into developing sex-specific treatment and prevention options for Alzheimer’s disease, the sixth-leading ...

Hearing loss affects more than 60 percent of adults aged 70 and older in the United States and is known to be related to an increased risk of dementia. The reason for this association is not fully understood. To better understand the connection, a team of University of California San Diego and Kaiser Permanente Washington Health Research Institute researchers employed hearing tests and magnetic resonance imaging (MRI) to determine whether hearing impairment is associated with differences in specific brain regions. In the November 21, 2023 issue of the Journal of Alzheimer’s Disease, researchers reported that individuals enrolled in this observational ...

University of Sussex researchers have developed a more energy-efficient alternative to transmit data that could potentially replace Bluetooth in mobile phones and other tech devices. With more and more of us owning smart phones and wearable tech, researchers at the University of Sussex have found a more efficient way of connecting our devices and improving battery life. Applied to wearable devices, it could even see us unlocking doors by touch or exchanging phone numbers by shaking hands. Professor Robert Prance and Professor Daniel ...

Day by day, we communicate with our office colleagues to accomplish tasks that are necessary to function. The more than 200 different types of cells in our bodies do the same thing, but the way they communicate with each other isn't as simple as sending an email.  Researchers like Ioannis Zervantonakis are still trying to understand how these cells actually communicate with each other. The assistant professor of bioengineering at the University of Pittsburgh Swanson School of Engineering recently received a National Institute of General Medical Sciences Maximizing Investigators' Research Award, and his project ...

Digital payment platforms such as Venmo work great for sharing a dinner bill with friends, buying gifts at a pop-up shop or making payments without cash or credit cards. But these digital payment platforms have a dark side: They can be misused for drug dealing and other illicit activity, suggest researchers from the University of California, Davis. And social media apps such as TikTok and Instagram can act as marketing tools for digital drug dealing. “While platforms like Venmo revolutionize financial interactions, they also highlight the need for ongoing vigilance and adaptive regulatory measures,” said Pantelis ...

The deep sea is home to one of the world's largest communities of animals about which we still know very little. Yet it is already subject to a growing number of human-induced environmental pressures. How do its inhabitants respond to these stressors? A new study led by researchers from the GEOMAR Helmholtz Centre for Ocean Research Kiel, published today in the scientific journal Nature Communications, provides first insights into the stress response of a deep pelagic jellyfish to ocean warming and deep-sea mining induced sediment plumes. One particular and potentially large environmental stressor for organisms in the deep ocean is the environmental ...

Female academics are significantly underrepresented in winning academic prizes and having awards named after them, a new study shows.   Analysis of nearly 9,000 awardees and 346 scientific prizes and medals published today (Tuesday 21 November) in Nature Human Behaviour has found that men win eight prizes for every one won by a woman if the award is named after a man. These awards represent almost two thirds of all scientific prizes.   Female academics are however more likely to win awards that have been named after other notable female scientists, with 47% of those awards going to women and 53% to men.   Dr Katja Gehmlich, Associate Professor in the Institute ...

  Leipzig/Mainz. The extent to which aerosol particles affect the climate depends on how much water the particles can hold in the atmosphere. The capacity to hold water is referred to as hygroscopicity (K) and, in turn, depends on further factors – particularly the size and chemical composition of the particles, which can be extremely variable and complex. Through extensive investigations, an international research team under the leadership of the Max Planck Institute for Chemistry (MPIC) and the Leibniz Institute for Tropospheric Research ...

WASHINGTON – U.S. Naval Research Laboratory (NRL) researchers have discovered solar-wind hydrogen in lunar samples, which indicates that water on the surface of the Moon may provide a vital resource for future lunar bases and longer-range space exploration. Space-based resource identification is a key factor in planning for civilian- and government-led space exploration. “Hydrogen has the potential to be a resource that can be used directly on the lunar surface when there are more regular or permanent ...

Scientists have identified the genes in the probiotic Bifidobacteria longum responsible for improving gut motility. A research team reporting November 21st in the journal Cell Host & Microbe found that B. longum strains possessing the abfA cluster of genes can ameliorate constipation through enhanced utilization of an indigestible fiber called arabinan in the gut. “We established the causal link between a genetic variant—the abfA cluster—to the key functional difference of probiotic B. longum in multiple model organisms, including mice and humans, and provided mechanistic and ecological insights ...

WASHINGTON, Nov. 21, 2023 – Forensic science has captured the public imagination by storm, as the profusion of “true crime” media in the last decade or so suggests. By now, most of us know that evidence left at a crime scene, such as blood, can often reveal information that is key to investigating and understanding the circumstances around a crime — and that scientific methods can help interpret that information. In Physics of Fluids, by AIP Publishing, a group of scientists from Boston University and the University of Utah demonstrated ...
