Starting antiretroviral therapy early essential to battling not one, but two killers
Medication against the nonhuman primate version of HIV given two weeks after infection helped keep tuberculosis in check.
Tracking seasonal and tidal effects on wastewater pollutants in the River Ganges
A new analysis of the River Ganges in West Bengal, India, highlights how wastewater flowing into the river impacts its water quality, and how that influence shifts with seasons and tides.
Study highlights worldwide disparities in treatment rates for major depressive disorder
A combined analysis of results from 149 earlier studies finds that treatment rates for major depressive disorder remain low worldwide, particularly for people living in low and lower-middle income countries.
Human microbiome research excludes developing world, study finds
New studies emerge daily on the effect of the human microbiome on human health: colon cancer, ulcers, and cognitive conditions such as Alzheimer’s disease have been associated with the communities of microbes that live in our bodies. However, global re…
Years of life lost during the pandemic significantly higher in deprived areas, study finds
The impact of the COVID-19 pandemic hit hardest in deprived areas of England and Wales, with excess years of life lost more than three times as high in the North West than the South West of England. The research also finds 11 times as many excess death…
Decoding KODA production to augment stress resistance in plants
KODA, an agrochemical produced in extremely low amounts, which helps plants cope with environmental stressors, has been the subject of extensive research. To bolster KODA production, researchers have developed a novel plant-based platform. Using biotec…
How embryo cells gain independence
It happens in the first hours after fertilization: The cells of the early embryo begin to independently produce proteins, the building blocks for cells and organs. Their own, uniquely composed genetic material serves as the blueprint. In vertebrates, t…
‘Blue Blob’ near Iceland could slow glacial melting
A region of cooling water in the North Atlantic Ocean near Iceland, nicknamed the ‘Blue Blob,’ has likely slowed the melting of the island’s glaciers since 2011 and may continue to stymie ice loss until about 2050, according to new research.
Algorithm could shorten quality testing, research in many industries by months
A machine-learning algorithm could provide auto manufacturing, aerospace and other industries a faster and more cost-efficient way to test bulk materials.
Air chemistry data from South Korea field study puts models to the test
An international effort to measure air quality in South Korea, a region with complex sources of pollution, may provide new insights into the atmospheric chemistry that produces ozone pollution, according to a team of scientists.
Outstanding question in theoretical models of memory addressed
A research team has discovered that communication between two key memory regions in the brain determines how what we experience becomes part of what we remember, and as these regions mature, the precise ways by which they interact make us better at for…
A new atlas of cells that carry blood to the brain
Researchers created a comprehensive atlas of the types of cells found in the brain cerebrovasculature, which provides oxygen and nutrients to the brain and helps form the blood-brain barrier. They also found significant differences between healthy cell…
Computer models show how crop production increases soil nitrous oxide emissions
A computer modeling study shows how the emissions of the greenhouse gas nitrous oxide have increased from soils over the last century. The newly published research found the expansion of land devoted to agriculture since 1900 and intensive fertilizer i…
Multi-country African research reports high rates of COVID-19-related deaths among hospitalized children and adolescents
African children and adolescents hospitalized with COVID-19 experience much higher mortality rates than Europeans or North Americans of the same age, according to a new study.
Predicting 30-day mortality risk for patients with alcohol-associated hepatitis
Researchers have developed a new scoring system to help health care professionals predict the 30-day mortality risk for patients with alcohol-associated hepatitis, and the tool appears to more accurately identify patients at highest risk of death and t…
Pandemic upends breast cancer diagnoses
Researchers surveyed and compared early- and late-stage breast and colorectal cancer diagnoses in patients in pre-pandemic 2019 and in 2020, the first full year of the COVID-19 pandemic, discovering fewer of the former and more of the latter as patient…
COVID-19 vaccination boosts mental health along with immunity, study finds
Receiving at least one vaccine dose was associated with statistically significant declines in multiple psychological distress factors, researchers report in a new study.
Climate change and extreme weather will have complex effects on disease transmission
Temperature fluctuations such as heatwaves can have very different effects on infection rates and disease outcomes depending on the average background temperature, says a new report.
Stem cell infusion boosts sepsis survival in mice
A one-time infusion of stem cells from bone marrow improves the survival of mice with sepsis.
How a protein controls the production of nerve cells in the brain
Researchers have discovered that the protein YME1L regulates the production of new nerve cells and the maintenance of neural stem cells in the adult brain. This holds great potential for regenerative treatments after brain injuries and other diseases.
