A team of MIT researchers has made significant progress on lithium-air batteries by identifying metal catalysts that can improve efficiency and increase energy density. The study finds that electrodes with gold or platinum catalysts show higher activity and efficiency than simple carbon electrodes.
Researchers have found that spraying low concentrations of a compound known as thidiazuron (TDZ) significantly extends the life of potted plants' leaves and flowers. In tests with greenhouse-grown cyclamen plants, TDZ-treated plants had a longer life than unsprayed plants.
Tropical Storm 23S has formed over the Southern Indian Ocean with maximum sustained winds of 39 mph. The storm is expected to strengthen and intensify over the weekend before being affected by a mid-latitude trough, potentially weakening it.
A landmark international study of over 60,000 women found that many are unaware of their risk factors for debilitating fractures, which can lead to chronic pain, reduced mobility, and increased mortality. The study emphasizes the need for improved education on osteoporosis risk factors and treatment options.
A new study explores the variability in fossil assemblages, finding that communities may be more resilient than thought. The researchers used living and fossil communities to investigate the factors affecting the low variability seen in fossil records.
Researchers found a positive correlation between individuals with a positive attitude towards physical activity and those who performed more unintentional physical activity. Unintentional activity, such as climbing stairs or walking further to reach a parking spot, can help burn extra calories.
A study found that leaving logging debris behind suppresses the growth of invasive plant species like Scotch broom and blackberry, allowing native plants to thrive. This method saves costs but may increase fire risk, making it a more favorable approach for forest management.
The TRMM satellite measured heavy rainfall totals from ex-tropical storm Paul, which left up to 11 inches of rain in northern Australia. The data confirmed significant flooding, with areas receiving between 100-200mm of rainfall and some reaching up to 300mm.
Researchers found that the amygdala distinguishes between different fear memories and retrieves them selectively. The study suggests a more sophisticated storage and recall capacity than previously thought, with implications for addressing specific fear memories.
Princeton engineers developed a technique to clarify images using rays of light scattered by clouds, human tissue, or murky water. The method, known as stochastic resonance, can potentially improve signal technologies such as sonograms, radar systems, and night vision goggles.
Researchers found that gene duplication events led to functional diversity in sunflower genes, including a gene variant that lengthened flower growth periods. This trait may have been favored by early Native Americans for domestication purposes.
Researchers have made significant findings on the state of stress in central and eastern North American seismic zones, providing insights into earthquake-generating stresses. Additionally, studies have mapped the depth domains of the Eastern Ghats Belt in India, offering clues to understanding ancient collisions.
Researchers at Princeton University have developed a new technique to produce electricity-conducting plastics, potentially lowering the cost of manufacturing solar panels. The breakthrough allows for the use of low-cost printing techniques and replaces expensive materials like indium tin oxide.
Researchers have uncovered the three-dimensional structure of a key protein found on the surface of a specific HIV-1 subgroup, providing valuable insights for vaccine design. The discovery reveals unusual autoreactivity between an anti-HIV antibody and the CD4 receptor, raising questions about potential autoimmune responses.
A new system developed by Texas AgriLife Research can automatically scan water samples and detect potential pathogens like cryptosporidium and giardia, providing results immediately. This technology has the potential to address key challenges in pathogen detection in food and water, making it accessible globally.
