Published Virtual reality becomes more engaging when designers use cinematic tools
(via sciencedaily.com) Original source Cinematography techniques can significantly increase user engagement with virtual environments and, in particular, the aesthetic appeal of what users see in virtual reality.
Published High genetic diversity discovered in South African leopards
(via sciencedaily.com) Original source Researchers say the discovery of very high genetic diversity in leopards found in the Highveld region of South Africa has increased the need for conservation efforts to protect leopards in the country.
Published Avocado pruning residues used to produce more sustainable food packaging
(via sciencedaily.com) Original source A prototype of a more durable material increases the biodegradability of food packaging, partially replacing its bioplastic with cellulose fibers extracted from the branches and leaves of the avocado tree.
Published Artificial intelligence tool detects male-female-related differences in brain structure
(via sciencedaily.com) Original source Artificial intelligence (AI) computer programs that process MRI results show differences in how the brains of men and women are organized at a cellular level, a new study shows. These variations were spotted in white matter, tissue primarily located in the human brain's innermost layer, which fosters communication between regions.
Published Using artificial intelligence to speed up and improve the most computationally-intensive aspects of plasma physics in fusion
(via sciencedaily.com) Original source Researchers are using artificial intelligence to perfect the design of the vessels surrounding the super-hot plasma, optimize heating methods and maintain stable control of the reaction for increasingly long periods. A new article explains how a researcher team used machine learning to avoid magnetic perturbations, or disruptions, which destabilize fusion plasma.
Published Artificial intelligence tool to improve heart failure care
(via sciencedaily.com) Original source The powerful new AI tool can predict heart failure outcomes in specific patients, helping doctors improve care.
Published First case of highly pathogenic avian influenza transmitted from cow to human confirmed
(via sciencedaily.com) Original source in March a farm worker who reported no contact with sick or dead birds, but who was in contact with dairy cattle, began showing symptoms in the eye and samples were collected by the regional health department to test for potential influenza A. Experts have now confirmed the first case of highly pathogenic avian influenza transmission from a mammal (dairy cow) to a human.
Published Coming out to a chatbot?
(via sciencedaily.com) Original source Today, there are dozens of large language model (LLM) chatbots aimed at mental health care -- addressing everything from loneliness among seniors to anxiety and depression in teens. But the efficacy of these apps is unclear. Even more unclear is how well these apps work in supporting specific, marginalized groups like LGBTQ+ communities.
Published Chatbots tell people what they want to hear
(via sciencedaily.com) Original source Chatbots share limited information, reinforce ideologies, and, as a result, can lead to more polarized thinking when it comes to controversial issues, according to new research. The study challenges perceptions that chatbots are impartial and provides insight into how using conversational search systems could widen the public divide on hot-button issues and leave people vulnerable to manipulation.
Published Persistent strain of cholera defends itself against forces of change, scientists find
(via sciencedaily.com) Original source A longstanding mystery about the strain of Vibrio cholerae (V. cholerae) responsible for the seventh global cholera pandemic is how this lineage has managed to out-compete other pathogenic variants. The team identified a unique quirk of the immune system that protects the bacteria from a key driver of bacterial evolution.
Published Insights into protein evolution
(via sciencedaily.com) Original source A research team has unveiled a breakthrough in understanding how specific genetic sequences, known as pseudogenes, evolve.
Published Just believing that an AI is helping boosts your performance
(via sciencedaily.com) Original source Sometimes it seems like an AI is helping, but the benefit is actually a placebo effect -- people performing better simply because they expect to be doing so -- according to new research. The study also shows how difficult it is to shake people's trust in the capabilities of AI systems.
Published Cats purrfectly demonstrate what it takes to trust robots
(via sciencedaily.com) Original source Would you trust a robot to look after your cat? New research suggests it takes more than a carefully designed robot to care for your cat, the environment in which they operate is also vital, as well as human interaction.
Published Fruit fly testes offer potential tool against harmful insects
(via sciencedaily.com) Original source A way to curb nagging insects has been flying under our radar -- an enzyme from fruit fly testes. The compound could control bugs that carry disease and harm crops by stunting their ability to procreate, researchers have found.
Published New work extends the thermodynamic theory of computation
(via sciencedaily.com) Original source Physicists and computer scientists have recently expanded the modern theory of the thermodynamics of computation. By combining approaches from statistical physics and computer science, the researchers introduce mathematical equations that reveal the minimum and maximum predicted energy cost of computational processes that depend on randomness, which is a powerful tool in modern computers.
Published New viruses that could cause epidemics on the horizon
(via sciencedaily.com) Original source Suddenly they appear and -- like the SARS-CoV-2 coronavirus -- can trigger major epidemics: Viruses that nobody had on their radar. They are not really new, but they have changed genetically. In particular, the exchange of genetic material between different virus species can lead to the sudden emergence of threatening pathogens with significantly altered characteristics.
Published Island birds more adaptable than previously thought
(via sciencedaily.com) Original source The researchers found that birds were more evolutionarily similar on smaller, more isolated islands than on larger, less remote places. The team had expected to find that forested areas had more numerous and more varied species of birds compared to farmland areas. But they were surprised to find that the opposite was true: Areas with farms and human settlements had more species of birds and greater diversity than forested areas.
Published Like dad and like mum ... all in one plant
(via sciencedaily.com) Original source Scientists have established a system to generate clonal sex cells in tomato plants and used them to design the genomes of offspring. The fertilization of a clonal egg from one parent by a clonal sperm from another parent led to plants containing the complete genetic information of both parents.
Published New molecule mimics the anti-clotting action of blood-sucking organisms
(via sciencedaily.com) Original source Nature gave ticks, mosquitoes and leaches a quick-acting way to keep blood from clotting while they extract their meal from a host. Now the key to that method has been harnessed by a team of researchers as a potential anti-clotting agent that could be used as an alternative to heparin during angioplasty, dialysis care, surgeries and other procedures.
Published Research on centromere structure yields new insights into the mechanisms of chromosome segregation errors
(via sciencedaily.com) Original source Researchers have made a surprising new discovery in the structure of the centromere, a structure that is involved in ensuring that chromosomes are segregated properly when a cell divides. Mistakes in chromosome segregation can lead to cell death and cancer development. The researchers discovered that the centromere consists of two subdomains. This fundamental finding has important implications for the process of chromosome segregation and provides new mechanisms underlying erroneous divisions in cancer cells. The research was published in Cell on May 13th 2024.
