Researchers report on effective treatments targeting racial and ethnic minorities, psychiatric disorders, and families with asthma. Cognitive-behavioral therapy significantly increased quit rates among African-American smokers, while family-focused approaches showed promising results for Latino families.
IEEE-USA presents $8,000 in scholarship awards and honoraria to recognize outstanding engineering video entries and public awareness contributions. Five undergraduate students from UNLV and LeTourneau University receive scholarships, while two journalists from Fox 5 Morning News and National Academy of Engineering are honored for their...
Research by scientists at the University of Missouri Center for Agroforestry suggests that buffer strips can trap and break down veterinary antibiotics in manure fertilizers. The finding aims to mitigate concerns about the use of veterinary antibiotics in livestock farming, which may lead to drug-resistant bacteria and ecosystem harm.
Researchers at UC Berkeley developed energy-scavenging nanofibers that can harness body movements to power hand-held electronics. The fibers have piezoelectric properties and high efficiency rates, enabling the creation of wearable 'smart clothes' with no perceptible change in comfort for users.
The Fraunhofer-Gesellschaft has developed a breakthrough technology for mobile television using Long Term Evolution (LTE), which offers higher performance capacity than UMTS. This enables seamless adaptive communication without disruptions, ensuring high-quality video streaming on the go.
Epigenetic signals vary across alleles in numerous genomic regions, influencing gene expression and regulation. The study reveals over 35,000 such sites across the genome, with implications for genetic studies of complex diseases, including psychiatric conditions.
Material scientists at Penn have demonstrated a way to convert optical radiation into electrical current using a molecular circuit. The system uses gold nanoparticles to induce and project electrical current, potentially powering devices with sunlight.
Researchers at Yale University have streamlined the synthesis of a family of compounds known as kinamycins, which are naturally produced by bacteria and show potent toxicity. By reducing the number of steps required to synthesize them from 24 to 12, the team can now prepare these molecules in larger quantities for further studies.
The SRC-3 gene enhances breast cancer growth and invasion by activating cell motility, allowing cancer cells to invade surrounding tissue. Researchers found that the gene enables an alternative form of its coactivator protein to function at the cell membrane, leading to increased cancer spread.
A team of researchers has completed a new analysis of the evolutionary relationships among arthropods, providing a solid grasp of what those relationships are. The study makes a major contribution to our understanding of the nature and origins of the planet's biodiversity.
awiloc software uses received signal strength data from WLAN transmitters to calculate position without data communications. This technology is integrated into various platforms, including Windows Mobile and Android, with support for iPhone expected by summer.
Researchers at Dartmouth College have discovered a protein structure controlling Vibrio cholerae's virulent nature. A fatty acid found within the protein appears to inhibit its function, preventing the bacteria from causing life-threatening diarrhea.
Researchers at University of Cincinnati identify p62 and ERK as a critical protein duo involved in adipogenesis. The study shows how the interplay between these proteins leads to uncontrolled ERK activity, highlighting ERK as a promising target for obesity therapies.
Researchers have developed new plant varieties to restore vegetation communities on the western rangelands, helping them survive extreme weather conditions. The newly created Hycrest II and Vavilov II cultivars offer improved establishment and resilience against invasive species.
The AAAS Fellowships for Science Reporters from North Africa provide recipients with a front-row seat at the unveiling of new research and opportunities to mingle with fellow science writers. The fellowship program supports excellence in communicating science worldwide, fulfilling AAAS and EurekAlert! mission goals.
Researchers found that amyloid beta peptides induce calcium waves in astrocyte networks, which could clarify what causes Alzheimer's disease and suggest new drug targets. The study provides a potential link between the accumulation of Amyloid beta fragments and sustained disruption of calcium balance within cells.
The study aims to better understand the cause, diagnosis, and history of preeclampsia and diabetes in pregnant women, particularly those with hypertension or obesity. Researchers hope to develop effective treatments and therapies to save lives, reducing maternal mortality and complications.
Researchers found that humans' heel-first gait is more efficient for walking due to reduced energy loss and improved muscle efficiency. However, there was no significant difference in efficiency between heel-first and toe-first postures while running.
Researchers discovered a link between antioxidant enzyme deficiency and impaired mitochondrial function, leading to muscle cell death. The findings offer new insights into sarcopenia and neuromuscular diseases, potentially paving the way for future muscle-preserving therapies.
Researchers at St. Michael's Hospital found that eating chocolate weekly may reduce the risk of stroke and death after suffering a stroke. Flavonoids in chocolate are believed to have a protective effect against stroke due to their antioxidant properties.
The London School of Hygiene & Tropical Medicine has received a $100,000 grant from the Rockefeller Foundation to trace its alumni and build an influential network of global health practitioners. The project aims to identify current leaders in low- and middle-income countries and strengthen capacity building.
A University of Utah study shows that heel-first walking is more economical for humans than ball-of-foot or toe walking. The research suggests that early human hunter-gatherers may have retained this foot posture due to its stability and agility advantages, despite being less efficient for running.
Researchers measure forces exerted on elephants to determine their movement patterns, finding that high-speed elephants exhibit characteristics of both running and walking. The study reveals that elephants' cost of transport is low due to efficient energy conversion, with a step frequency higher than expected.
