Research by UCSF scientists reveals two gene variants associated with longer telomeres also increase the risk of developing gliomas. Despite being carried by a majority of people, these genetic variants may promote overall health due to their protective effect on cells from aging.
New research reveals how a quick-escape circuit in the fly's brain overrides slower behavior when an urgent threat is detected. Flies can choose between long and short escapes, with quicker escapes often resulting in clumsier movements.
A recent study analyzed 10 diverse citrus varieties and found very limited genetic diversity, which could threaten the crop's survival. The researchers hope to enable sequence-directed improvement to produce crops that better resist diseases and environmental changes through modern genomics-guided development.
Scientists at EPFL introduce a novel biosensor molecule that can quickly measure drug concentration in patients' systems using a digital camera. The method is simple, low-cost, and can be used by patients themselves.
Researchers at McGill University discovered a tiny molecule, miR-1202, that regulates glutamate receptors and is lower in the brains of depressed individuals. The study found that this microRNA increases with antidepressant treatment, suggesting it could be a potential target for developing new treatments.
Healthcare experts examine potential cost savings in maternal mortality reduction, adolescent cancer treatment, and biosimilar medication use. Studies reveal the importance of long-term financing plans and access to follow-up care for improved outcomes.
The common bean genome sequence reveals genes involved in critical traits such as size, flavor, and disease resistance. Identifying these genes will help researchers develop more nutritious and climate-resilient bean varieties.
A study by Weizmann Institute researchers found that human activities have altered the types of clouds over pristine ocean areas, leading to increased cloud height and rainfall. The team's model accurately predicted these changes using satellite images and aerosol data, suggesting a significant impact on global climate patterns.
Researchers have analyzed and compared the genomes of ten diverse citrus varieties, revealing that they originated from two wild citrus species diverged in Southeast Asia over five million years ago. The study provides valuable insights into disease resistance and breeding strategies for improving citrus yields.
Researchers at the University of Minnesota found that rats were willing to wait longer for certain flavors, indicating individual preferences. The study suggests that regret is a fundamental cognitive process shared among mammals.
The Phaseolus genome study provides valuable information on the genetic basis of nitrogen fixation in common beans, a crucial legume for agricultural sustainability. The research identified dense clusters of genes related to disease resistance and nitrogen metabolism, offering potential targets for future crop improvement efforts.
A study suggests that warming climates can indirectly increase CO2 levels in the atmosphere by reducing iron and silicon availability in ocean waters. This is particularly significant in the southern ocean and equatorial Pacific, which play a crucial role in regulating atmospheric CO2.
The researchers designed a nanoparticle with a peptide coating to target tumor cells, allowing for efficient drug delivery. The shell is etchable, enabling the removal of excess particles using biocompatible chemicals.
