Researchers from Singapore found that carotenoids decrease hip fracture risk in lean, elderly Chinese men. Low BMI is a stronger risk factor for hip fractures in men compared to women, according to the study.
A new model reveals that viruses construct intermediate structures before final capsid production, outperforming direct assembly in efficiency. This method allows the viral genome to be protected and propagated successfully, even without host cells.
Researchers have developed a new technique to create targeted immunotherapies for cancer, recognizing antigens on cancer cells that are not found on healthy cells. The approach uses chimeric antigen receptors (CARs) and costimulatory receptors (CCRs), allowing T cells to attack specific types of cancer cells while sparing normal cells.
Researchers have developed a groundbreaking mind-controlled prosthetic hand that allows users to control it with remarkable accuracy and naturalism. The device has been tested in a clinical trial, achieving a success rate of up to 91.6% and demonstrating clinically significant improvement.
Researchers say limiting global temperature rise to 2°C requires reducing emissions to 41-47 gigatons per year by 2020. This is the only way to meet long-term climate targets without carbon capture and storage, according to a new study published in Nature Climate Change.
Cedars-Sinai researchers have successfully converted ordinary heart cells into pacemaker cells using a single gene, Tbx18. The new cells generate electrical impulses and are indistinguishable from native pacemaker cells, offering a potential alternative to electronic pacing devices.
Five young investigators from the Asia-Pacific region were awarded prestigious grants for their top-ranking abstracts. The IOF Young Investigator Award valued at USD 1,000 and invited them to present their work in oral presentations during a special plenary session.
The inclusion of intense but small-scale polar storms in climate models could lead to a different picture of climate change. Adding these storms results in significant changes in ocean circulation, including an increase in heat traveling north in the Atlantic Ocean.
A recent study found that older patients hospitalized with critical illness are at increased risk of developing dementia. The study, published in Critical Care, identified infection, neurological dysfunction, and acute renal failure as independent risk factors for dementia diagnosis.
Researchers found iron 60, a radioactive sign of an exploding star, in low abundance and uniformly distributed in solar system material. The findings suggest the low levels of iron 60 likely came from long-term accumulation of iron 60 in interstellar medium rather than a nearby cataclysmic event.
A study published in Nature Neuroscience found that male rats exposed to cocaine showed resistance to its rewarding effects when given the drug as adults, while their female offspring did not. The researchers believe that this may be due to changes in gene expression triggered by paternal exposure to cocaine.
A new study found that even small strokes can harm neural tissue and alter behavior in rats. Blocking tiny blood vessels in the brain can lead to micro-lesions reminiscent of those seen in dementia patients. The FDA-approved drug memantine showed promise in mitigating these effects.
Researchers reconstructed giant panda's continuous population history from origin to present, revealing global climate change as primary driver of fluctuations. Human activities likely underlie recent population divergence and decline, with local adaptations identified in sensory system genes.
Researchers at Monash University used advanced microscopy techniques to visualize the movements of white blood cells in healthy and diseased kidneys. They found that leukocytes are constantly circulating through and patrolling blood vessels within healthy kidneys, but become agitated during disease, causing inflammation and kidney damage.
A new method creates ontology, a specification of all major players in the cell and their relationships, from large datasets. The approach captures known cellular components and identifies potentially new biological components, triggering updates to existing databases.
A new climate model simulates the effects of Arctic hurricanes on ocean water circulation and climate, suggesting potentially cooler conditions in Europe and North America. The research finds that polar lows influence the sinking of dense cold water in the North Atlantic, driving large-scale ocean circulation.
