A new study published in Science Advances found that a drug called phenylbutyrate can help cells clear herpes simplex 1 and 2 viruses. When used in combination with acyclovir, the drug combo is more effective and reduces side effects associated with long-term use of acyclovir.
The COVID-19 pandemic has worsened existing health disparities in pediatric care, with increased gaps in physical and mental health services. Telehealth can help bridge these gaps, reducing healthcare disparities.
A new study analyzed the relationship between working life expectancy and health expectancies, revealing potential to increase expected economically active years for both men and women. However, education-specific analysis showed large differences in size of this potential among socioeconomic subgroups.
Researchers used machine learning to analyze brain network data from people with major depressive disorder, identifying distinct patterns of coordinated brain activity. The new brain network signature achieved 70% accuracy in detecting major depression across different imaging protocols.
Fossil discovery provides insights into ancient Tibetan biota and land surface height in the middle Eocene. The study reveals a diverse and humid subtropical forest ecosystem at an elevation of 1,500 meters under a monsoonal climate.
Kyoto University researchers highlight the need for targeted conservation efforts due to 90% extinction risk for Japanese bat species. The study reveals poor alignment between conservation needs and research resource allocation, with many threats understudied.
A new study reveals an average of 120,232 firearm injuries per year in the US, with nonfatal cases being twice as prevalent as deaths. The research highlights the need for effective prevention strategies beyond just addressing fatal injuries.
A new study documents bonefish diving 450 feet deep to spawn, a rare behavior in shallow water fish. The research provides crucial information for conservation efforts, informing techniques used to rear captive spawned bonefish larvae and better focus habitat conservation.
Researchers at the University of Leicester are helping community groups in Rio de Janeiro's favelas develop digital storytelling skills through a virtual tourism platform called Lockdown Stories. The project aims to empower individuals and communities within the favelas, reducing their isolation and increasing access to global audiences.
Research reveals Xylella fastidiosa transmission peaks in July and August, affecting grapevine Pierce's disease in California. The study suggests late-season infections are more likely to persist, highlighting the need for regionally specific data.
A new longitudinal analysis of 254 COVID-19 patients reveals that IgA and IgM antibodies disappear quickly during convalescence, while IgG antibodies persist but decline slowly. The study's findings may impact seroprevalence studies and raise questions about vaccination durability.
The German National Academy of Sciences Leopoldina has published a report on the future of ageing and life course research in Germany, outlining recommendations for advancing research on ageing. The report highlights challenges arising from the COVID-19 pandemic and compares Germany's performance to other countries.
The study showed that the combination of chemotherapy and blinatumomab resulted in increased survival rates and achieved a high rate of MRD negativity for patients with Ph-negative B-cell ALL. This treatment approach has the potential to improve long-term outcomes for these patients.
Researchers at the University of Bath found that children learn about evolution more effectively when engaged through stories read by the teacher, rather than through doing tasks. The story-based approach combined with abstract examples was the most effective in improving pupils' understanding of evolutionary concepts.
A new study identifies a method that detects COVID-19 in wastewater samples and tracks infection trends. The test uses genetic material from SARS-COV-2 RNA, which correlates with community COVID-19 infections.
A novel harmonization method was used to develop a generalizable brain network marker for major depressive disorder (MDD), based on resting-state fMRI data. The marker achieved approximately 70% generalization accuracy for an independent validation dataset, demonstrating its potential for clinical applications.
