A new form of wave devouring propulsion (WDP) could power ships and help to cut greenhouse gas emissions in the maritime industry.   Academics from Cranfield University have worked on the concept of using wave energy for propulsion, and designed an inventive method of achieving greater thrust from the power of the waves by harnessing a vessel’s submerged flapping foils in an innovative way.   Inspiration from whale fins   Taking inspiration from the power of a whale's fins, the team studied the structure and movement of the tail fin to unravel how it effectively uses wave energy for propulsion. Through simulations and experiments, they developed ...

Recommender systems are machine learning applications in online platforms that automate tasks historically done by people. In the news industry, recommender algorithms can assume the tasks of editors who select which news stories people see online, with the goal of increasing the number of clicks by users, but few studies have examined how the two compare. A new study examined how users of an online news outlet in Germany reacted to automated recommendations versus choices made by human editors. On average, the algorithm outperformed the person, but the person did better under certain conditions. The study’s authors suggest a combination of human curation and automated recommender ...

(Boston)—Breast density information aims to increase awareness of breast density and its risks and inform future breast screening decisions. Breast density notifications (BDN) advise women to discuss breast density with their clinicians, but prior research shows less than half of women in the general population have those conversations and little is known about the content of conversations that do occur.    A new study by researchers from Boston University Chobanian & Avedisian School ...

Scientists have simulated conditions that allow hazy skies to form in water-rich exoplanets, a crucial step in determining how haziness muddles observations by ground and space telescopes. The research offers new tools to study the atmospheric chemistry of exoplanets and will help scientists model how water exoplanets form and evolve, findings that could help in the search for life beyond our solar system. “The big picture is whether there is life outside the solar system, but trying to answer that kind of question requires really detailed modeling of all different types, specifically in planets with lots of water,” said co-author ...

Scientists have made a surprising discovery that sheds new light on the role that oceanic deoxygenation (anoxia) played in one of the most devastating extinction events in Earth’s history. Their finding has implications for current day ecosystems – and serves as a warning that marine environments are likely more fragile than apparent. New research, published today in leading international journal Nature Geosciences, suggests that oceanic anoxia played an important role in ecosystem disruption and extinctions in marine environments during the Triassic–Jurassic mass extinction, ...

Antibodies—proteins that are produced by our immune system to protect us—are crucial for recognizing and getting rid of unwanted substances, or antigens, in our body. Although their role is universal, antibody structure varies in different animals. In a new study, researchers have analyzed the antibody Immunoglobulin M in rainbow trout to shed some light on why these proteins may have evolved over time. In humans, IgM consists of five repeating units that are held together by a joining chain, resulting in a star shape. Consequently, IgM can bind to multiple antigens at the ...

ITHACA, N.Y. – Bitcoin mining is often perceived as environmentally damaging because it uses huge amounts of electricity to power its intensive computing needs, but a new study demonstrates how wind and solar projects can profit from bitcoin mining during the precommercial development phase — when a wind or solar farm is generating electricity, but has not yet been integrated into the grid. The findings suggest some developers could recoup millions of dollars to potentially invest in future renewable energy projects. The ...

Vampire bats may soon take up residence in the United States and bring with them an ancient pathogen. “What we found was that the distribution of vampire bats has moved northward across time due to past climate change, which has corresponded with an increase in rabies cases in many Latin American countries,” said Paige Van de Vuurst, a Ph.D. student in Virginia Tech’s Translational Biology, Medicine, and Health Graduate Program.  Van de Vuurst is the lead author of research recently published in the Ecography journal that predicts ...

To teach an AI agent a new task, like how to open a kitchen cabinet, researchers often use reinforcement learning — a trial-and-error process where the agent is rewarded for taking actions that get it closer to the goal. In many instances, a human expert must carefully design a reward function, which is an incentive mechanism that gives the agent motivation to explore. The human expert must iteratively update that reward function as the agent explores and tries different actions. This can be time-consuming, inefficient, ...

Dietary food intake has a major influence on health indicators, including Body Mass Index (BMI), blood pressure, serum cholesterol and glucose. Previous research has shown that decisions to purchase specific food items are primarily based on taste and cost. In the United States, only 12 percent and 10 percent of adults meet fruit and vegetable intake recommendations, respectively. Since affordability of food items is a limiting factor for meeting fruit and vegetable intake guidelines, researchers hypothesize that more affordable low energy-dense foods like fruits and vegetables, which are relatively more expensive ...

In recent years, cell and gene therapies have shown significant promise for treating cancer, cystic fibrosis, diabetes, heart disease, HIV/AIDS and other difficult-to-treat diseases. But the lack of effective ways to deliver biological treatments into the body has posed a major barrier for bringing these new therapies to the market — and, ultimately, to the patients who need them most.   Now, Northwestern University synthetic biologists have developed a flexible new platform that solves part of this daunting delivery problem. Mimicking natural ...

About The Study: School shooting incidents in the U.S. were typically executed using low- and moderate-powered firearms, according to this analysis of data from 262 adolescents who discharged firearms in 253 school shootings spanning 26 years. These weapons were most frequently stolen from family members or relatives of the perpetrators. These findings may significantly influence discussions around gun control policy, particularly in advocating for secure firearm storage to reduce adolescents’ access to weapons.  Authors: Brent R. Klein, Ph.D., of the University of South Carolina in Columbia, is the corresponding author. To access ...

About The Study: Excess cardiovascular mortality among former smokers was about one-third that of continuing smokers within the first decade after quitting, and the cardiovascular mortality rate of former smokers was similar to that of never smokers 20 to 29 years after quitting in this study of 438,000 U.S. adults. These findings emphasize that with sustained cessation, cause-specific mortality rates among former smokers may eventually approximate those of never smokers.  Authors: Blake Thomson, D.Phil., of the Stanford University School of Medicine in Stanford, California, is the corresponding author. To access the embargoed study: Visit our For The Media website at ...

The two-year study compared cognitive ...

An international team has shown that the injection of a type of stem cell into the brains of patients living with progressive multiple sclerosis (MS) is safe, well tolerated and has a long-lasting effect that appears to protect the brain from further damage. The study, led by scientists at the University of Cambridge, University of Milan Bicocca and Hospital Casa Sollievo della Sofferenza (Italy), is a step towards developing an advanced cell therapy treatment for progressive MS. Over 2 million people live with MS worldwide, ...

PITTSBURGH, Nov. 27, 2023 – Common neuropsychiatric symptoms that doctors see in Alzheimer’s disease patients originate from brain inflammation rather than amyloid and tau proteins, report University of Pittsburgh School of Medicine researchers today in JAMA Network Open. The finding strengthens mounting evidence for the role of neuroinflammation in Alzheimer’s progression and suggests new pathways for the development of therapies targeting neurological symptoms of the disease. “Neuropsychiatric symptoms such as irritability, agitation, anxiety and depression are among the most difficult ...

Nearly a third of the world’s mine tailings are stored within or near protected conservation areas, University of Queensland research has found. A study led by UQ’s Bora Aska, from the Sustainable Minerals Institute and School of the Environment, said these waste facilities pose an enormous risk to some of earth’s most precious species and landscapes. “Mine tailings contain the waste and residue that remains after mineral processing, and the storage facilities built to contain it are some of the world’s largest engineered structures,” Ms Aska said. “We found of the 1,721 disclosed tailings ...

Whether infants at five months of age look mostly at faces or non-social objects such as cars or mobile phones is largely determined by genes. This has now been demonstrated by researchers at Uppsala University and Karolinska Institutet. The findings suggest that there is a biological basis for how infants create their unique visual experiences and which things they learn most about. The study has been published in the scientific journal Nature Human Behaviour. The way in which we explore our environment with our eyes affects what we notice, think about and learn. The new study analysed preference for faces versus non-social objects in ...
