A new agent has been developed to treat overdoses using peritoneal dialysis, which can extract up to a hundred times more toxins from the body than conventional alternatives. This method is especially effective for treating serious liver disease, including cases involving ammonia accumulation in the blood.
Two new pill-only regimens have been developed to treat genotype 1 hepatitis C, with a sustained virological response achieved in 90% of previously untreated patients and 82% of those who failed previous treatment. These regimens show promise as simpler, safer, and faster alternatives to current therapies.
Researchers use 'pool sequencing' to analyze entire groups of organisms, allowing for rapid evolution experiments and discovery of genetic factors influencing aging and disease resistance. The approach provides insights into how evolution works and has potential applications in understanding climate change.
Evolutionary biologist Steven Ramm explores sperm competition as a key driver of reproductive system evolution, highlighting the diversity of sperm cells and their adaptations to compete for fertilization. This research could inform genetic modification to increase fertility in endangered species.
A study by Massachusetts General Hospital found that hospitals struggled to meet guidelines for asthma care, particularly those with weaker scientific evidence. The study suggests that overcrowding and crowding may contribute to the decline in meeting non-level-A recommendations.
A study by University of Wisconsin-Madison researchers found that climate change is causing smaller, southerly distributed bird species to move northwards, altering the composition of winter bird communities in eastern North America. This shift is likely driven by warmer temperatures and changing precipitation patterns.
Researchers found that individuals with severe mental illness use YouTube to share personal stories, strategies for coping, and seek support from others. This natural peer-to-peer connection helps alleviate feelings of loneliness and fosters a sense of hope and community.
Scientists at the University of Birmingham discovered how a rare fungus, Cryptococcus gattii, can infect healthy individuals by exploiting the body's immune response. The fungus triggers a 'division of labour' in its invading cells, allowing it to establish itself and cause life-threatening infections.
A cost-value review of specialty versus traditional drugs found that specialty drugs offered greater gains for patients despite higher costs. Specialty drug coupons helped reduce patient out-of-pocket costs but may decrease insurers' ability to manage drugs.
A University of Georgia study found that disruption of the circadian rhythm, triggered by artificial light exposure, significantly increases breast cancer risk. The researchers analyzed studies on flight attendants who work night shifts and found a higher risk of developing breast cancer.
Researchers discovered how immune cells consume oxygen and restrict bacterial growth in cystic fibrosis patients. This study provides new insights into bacterial behavior and growth in chronic infections.
Tropical Storm Ana is nearing hurricane strength and expected to become a hurricane before reaching the Big Island of Hawaii. The storm's outer clouds are already affecting the island, causing heavy rainfall and potentially life-threatening flash floods and mudslides.
The NIH has awarded over $11 million to support research on using social media to advance the scientific understanding, prevention, and treatment of substance use and addiction. The studies aim to better understand how social media affects behavior and attitudes towards alcohol, tobacco, and other addictive substances.
Researchers have solved a long-standing mystery surrounding Australia's only active volcanic area, which spans over 500 kilometers and has seen more than 400 volcanic events in the last four million years.
A University of Toronto study found that chronic video game players have an advantage in learning new sensorimotor skills compared to non-gamers. Gamers performed better at tracking complex patterns and following repetitive motions, indicating enhanced ability to learn dynamics of new tasks.
The nanocryotron device uses a single layer of niobium nitride deposited on an insulator to create a simple superconducting circuit. By controlling the flow of current through the circuit, it can act as a switch, making it a potential component for digital computers.
Researchers at the University of Bristol used computer simulations to study how bacteria destroy antibiotics, identifying enzymes that break down carbapenems quickly and slowly. This insight will help scientists develop new antibiotics with lower resistance rates.
A recent study by researchers at The Miriam Hospital found that newborns of mothers who smoke cigarettes during pregnancy show lower levels of stress hormones and altered DNA. This may lead to a higher risk of behavior problems and nicotine addiction in later life.
A new study published in Diabetologia found that children infected with enterovirus were 48% more likely to develop type 1 diabetes. The study's results suggest a positive correlation between EV infection and the incidence of type 1 diabetes, which may be driven by environmental factors in regions with high EV prevalence.
New research shows that female rhesus monkeys exhibit a bias toward images of the opposite sex when surrounded by red frames, mirroring human responses. This finding suggests an evolved biological mechanism underlying the 'red effect', which may not be unique to humans.
Researchers found that regular poor trimming can cause residual stress in nails, leading to shape changes and serious conditions. They suggest optimising nail shapes to reduce stress and promote health in both humans and animals.
The Journal of Disaster Medicine and Public Health Preparedness has launched a special issue on Ebola, featuring a clinician primer prepared by Dr. Eric Toner and colleagues. The primer covers the history, epidemiology, microbiology, clinical manifestations, biosafety, prevention, treatment, and experimental vaccines of the Ebola virus.
A study published in Practical Radiation Oncology evaluated the use of image-guided radiation therapy (IGRT) in treating pediatric cancers. The results show that IGRT is commonly used to improve localization and precision in radiation delivery, particularly for tumors near sensitive structures or organs.
