The CARICOMP program found significant decreases in water quality at 42% of the monitoring stations across the Caribbean basin. Despite expected increases in water temperature due to global warming, no such changes were detected in the data set.
A PSU researcher has discovered that small inland ponds account for a significant portion of carbon dioxide and methane emissions from inland waters. Her study, published in Nature Geoscience, revealed that these small ponds, despite being only 9% of the total surface area, contribute 15% of CO2 emissions and 41% of methane emissions.
For the first time, researchers have captured detailed information on human sleep cycles over long periods of time while individuals slumber at home. The wrist-worn gadget, called an actimeter, records data on wrist movement to assess rest/activity cycles during sleep.
Researchers at Scripps Research Institute use nuclear magnetic resonance spectroscopy to study the A2a adenosine receptor, revealing its dynamic structure and a
Researchers discovered a new protein, CTL1, essential for ion homeostasis in plants. It regulates vesicle trafficking and affects plant growth and development by controlling auxin transporters.
UC San Francisco bioengineers develop a method to create complex tissue shapes, such as bowls and coils, by patterning cells on thin layers of extracellular matrix fibers. This approach mimics natural developmental processes and offers new insights into the fundamental biology of tissue assembly.
A survey of residents near two national parks in Panama found that jaguars deserve increased protection due to human-jaguar conflict. The study suggests that educating stakeholders about the connection between healthy ecosystems and jaguar survival is crucial for effective park management.
Researchers developed a gene therapy approach using CAR T-cells to target and destroy HIV-infected cells, achieving sustained immunity of over two years in test animals. The engineered cells effectively attacked and killed HIV-infected cells without adverse effects.
Researchers from Ural Federal University and Karaganda State Technical University developed a mathematical model to optimize the operation of an autonomous heat supply unit. The study found that adjusting parameters such as blade size in the Cavitator increased cavitation intensity and temperature, improving efficiency.
Researchers found that estrogen treatment exerts positive effects on immune cells in the brain and oligodendrocytes, providing complementary actions that protect against MS damage. Estrogen's protective effect is mediated by protein ERb, targeting both cell types for disease prevention.
Researchers analyzed medical records of 487,104 black women and found that those with CCCA had a significantly higher prevalence of uterine fibroids compared to controls. The findings suggest a possible link between the two conditions, warranting increased awareness among physicians and patients.
The Genes in Space-3 team achieved the first-ever sample-to-sequence process entirely aboard the International Space Station, identifying two previously unknown microorganisms. The breakthrough could aid in diagnosing astronaut ailments, identifying DNA-based life on other planets, and benefiting other experiments.
Researchers Ryosuke Omori and Jianhong Wu develop an inductive algorithm to study site-specific nucleotide frequencies using a multi-strain SIR model. The algorithm calculates Tajima's D, a statistical test that measures natural selection at a specific site.
Researchers have identified 22 high-risk districts in Uganda where cholera outbreaks are more likely due to proximity to international borders and bodies of water. These districts are recommended for strengthened collaboration with neighboring countries to control the spread of cholera.
Tropical Cyclone Hilda formed near Australia's northwest coast, with NASA's GPM satellite detecting heavy precipitation. The storm intensified to a tropical storm before dissipating over land, bringing a Tropical Cyclone Warning to the region.
A new micro-needle patch has shown promise in laboratory trials for reducing bulging tummy fats by turning energy-storing white fat into energy-burning brown fat. The patch reduces weight gain and fat mass in mice on a high-fat diet over four weeks.
Research identifies missense mutations in NF1 gene as risk factor for severe neurofibromatosis symptoms. Patients with these mutations show high incidence of benign tumors and malignancies.
Researchers at TUM and Harvard University discovered a substance that interferes with the formation of Mycobacterium tuberculosis' mycomembrane. Combining this beta-lactone inhibitor with known antibiotics increases effectiveness by up to 100-fold, making it a promising new therapy for TB.
A recent study by UPV/EHU researchers shows that the interaction between the North Atlantic Oscillation (NAO) and the Atlantic Multidecadal Oscillation (AMO) controls forestry productivity in the Iberian Peninsula. The research reveals how these climate modes affect droughts, winters, and ecosystem productivity.
A new study published in PLOS ONE found that female students outperform male students on biology courses where exams count for less than half of the total grade.
