Companies that proactively manage climate risks boost their valuations, while those with a passive stance are discounted in the equity market, according to new research.
A group of scholars calculated the amount of energy used by AI tools for the tasks of writing and illustrating and compared it to the average amount of energy humans use for the same processes. Their results showed artificial intelligence results in hundreds of times less carbon emissions than humans. This does not mean, however, that AI can or should replace humans in those tasks, simply that its energy usage is less. The better approach is a partnership between humans and AI, the authors write.
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.
Australia could soon see megadroughts that last for more than 20 years, according to new modelling. The researchers' bleak findings are before factoring in human impact on the climate since the Industrial Revolution. According to the scientists, the findings paint a worrying picture of future droughts in Australia that are far worse than anything in recent experience.
Energy harvesting, an eco-friendly technology, extends beyond solar and wind power in generating electricity from unused or discarded energy in daily life, including vibrations generated by passing car engines or trains. Recent intriguing research has been announced, aiming to enhance the efficiency of energy harvesting using a new type of metasurface that can be reconfigured, resembling the assembly of LEGO bricks.
New research suggests animals can thrive in human-dominated environments by being expert judges of risk. Researchers examined the behavior of great-tailed grackles, a bird species successfully invading much of urban North America, showing that the dispersing males shy away from risk, which is a characteristic the researchers show is well-suited to chaotic environments like cities. These findings provide unique insight into how and why animals and humans can coexist.
An international team of scholars present the earliest clear archaeological and biomolecular evidence for the raising of chickens for egg production, based on material from 12 archaeological sites spanning one and a half millennia. The research indicates that the domestic chicken, now a staple in diets around the world, is not as ancient as previously thought.
Cell damage from oxidative stress is a major underlying cause of age-related cognitive and muscle strength decline. Antioxidants can reduce oxidative stress and prevent age-related health decline. A new study has found that mice administered with a blended antioxidant supplement show significant improvements in spatial cognition, short-term memory, and mitigated age-related muscle decline. The study suggests that blended antioxidant supplements hold promise as a dietary intervention for health issues associated with aging.
Osteosarcoma is a type of bone cancer that predominantly affects adolescents. Reliable models that can predict prognosis and treatment response can help improve patient outcomes. However, conventional methods relying on the measurement of necrosis rate are limited by inter-assessor variability and may not accurately predict prognosis. Now, researchers have developed an AI model that can accurately measure the density of viable tumor cells after treatment which correlates well with prognosis and individual tumor cell response.
Little progress had been made in solving Ramsey problems since the 1930s. Now, researchers have found the answer to r(4,t), a longstanding Ramsey problem that has perplexed the math world for decades.
New screening tools in child health care are effective in identifying early language and communication difficulties in children. This is shown by two studies based on more than 6,000 children.
Researchers have used computational models to understand what drives the accumulation of alpha-synuclein protein, a key culprit in the development of Parkinson's disease.
The oldest trees in the forest help to prevent the disappearance of endangered species in the natural environment, according to a new study. This is the case of the wolf lichen -- threatened throughout Europe --, which now finds refuge in the oldest trees in the high mountains of the Pyrenees. This study reveals for the first time the decisive role of the oldest trees in the conservation of other living beings thanks to their characteristic and unique physiology.
Engineers have created ultraviolet (UV) rays-emitting glass that can reduce 98% of biofilm from growing on surfaces in underwater environments.
Researchers are using semiconductors to harvest and convert the sun's energy into high-energy compounds that have the potential to produce environmentally-friendly fuels.
A novel treatment for leukemias and lymphomas that arise from immune system T cells was found to be effective at killing these cancers in mice bearing human T-cell tumors.
Polymer-based hydrogels are used to treat skin ailments and in tissue engineering because of their ability to retain water, deliver drugs into wounds, and biodegrade. However, they are complicated to manufacture and not very resilient to external forces like rubbing against clothing, sheets, or wound dressings. Scientists have now created a hydrogel enhanced with the amino acid polylysine and blood plasma that is easier to synthesize, contains natural antibiotic properties, and promotes cell growth.
Changes in the gut microbiome have been implicated in a range of diseases including type 2 diabetes, obesity, and inflammatory bowel disease. Now, a team of researchers has found that microbes in the gut may affect cardiovascular disease as well. The team has identified specific species of bacteria that consume cholesterol in the gut and may help lower cholesterol and heart disease risk in people.
Researchers have taken a big step towards securing information against hacking. They have succeeded in using quantum encryption to securely transfer information 100 kilometers via fiber optic cable -- roughly equivalent to the distance between Oxford and London.
All-solid-state lithium-ion batteries offer enhanced safety and energy density compared to liquid electrolyte counterparts, but face challenges like lower conductivity and insufficient electrode contact. In a recent study, scientists have discovered a stable, highly conductive lithium-ion conductor in the form of a pyrochlore-type oxyfluoride. This innovation addresses the need for non-sulfide solid electrolytes, offering higher conductivity and stability and paves the way for advanced all-solid-state lithium-ion batteries with improved performance and safety.
