The collaboration between Corwin and Heller at the Marine Biological Laboratory is an important breakthrough.
Researchers at Johns Hopkins University have developed a new set of molecules that can catalyze the cleanup of common groundwater pollutants called organohalides. The compounds 'break bonds' holding dangerous pollutants together, rendering them safer.
A 117-year coastal temperature record at Woods Hole, Massachusetts, shows sustained warming since the 1960s. The data reveals a significant increase in water temperatures during the past few decades, with averages rising by up to 1.2?C over the annual cycle.
Researchers have created a group of rhodium-based compounds that can target and kill cancer cells, as well as deactivate viruses like West Nile and yellow fever viruses. These compounds work by binding to DNA in tumor cells and rendering them inert, and they offer a promising alternative to traditional chemotherapy drugs.
The JGI Community Sequencing Program (CSP) selects a diverse range of organisms, including moss, sponge, leech, and red tide algae, to advance knowledge on alternative energy production, bioremediation, and evolution. These projects will leverage JGI's powerful resources to sequence approximately 15 gigabases of genetic code.
Virginia Tech researchers have developed light-activated therapy agents that are oxygen independent, overcoming a limitation in photodynamic therapy. The new agents are activated by visible light and have been studied in cell cultures, showing promising results.
A study of 91,249 women found a strong association between frequent consumption of sugar-sweetened beverages and increased risk of type 2 diabetes. Women who consumed more sugar-sweetened drinks experienced greater weight gain and higher risk of developing the condition.
According to a study by Yale University, older female runners aged 50-59 improved their average race time by 2.08 minutes per year, significantly exceeding male runners of the same age. The older male runners also showed an accelerated rate of improvement, outperforming younger men in the 60-69 and 70-79 age categories.
The new database will allow researchers to submit a single chemical inventory once a year, reducing the need for frequent updates. It will also screen for hazardous chemicals and explosives, providing critical information in emergency situations and helping prevent laboratory accidents.
Researchers at UGA identified morning glory families tolerant to glyphosate, a noxious herbicide. The study suggests developing regional strategies for managing tolerance is crucial. Increased tolerance of morning glories to glyphosate could leave farmers without effective control, highlighting the need for new management strategies.
Researchers at the University of Illinois have developed a polymer-based colloidal adsorbent that effectively removes troublesome natural organic matter from municipal water supplies. The technology reduces the formation of harmful chlorinated compounds, ensuring safer drinking water without creating dangerous byproducts.
A randomized trial found that telephone-based psychotherapy added significantly to usual care pharmacotherapy for patients with depression. The study showed improved patient-rated improvement and satisfaction rates compared to usual care.
Scientists at the University of Pennsylvania are developing innovative techniques to study biomolecules within cells and living systems. They have created
A US national study is seeking women who have donated eggs prior to May 2001 to understand their physical and emotional experience. The research aims to analyze the role of payment in women's motivation to donate eggs, a practice common in the US but not allowed in other countries.
Research suggests that higher levels of testosterone and dihydrotestosterone hormones give male Townsend's warblers a competitive advantage over female hermit warblers. The findings indicate that the hermit warbler may become extinct in another 5,000 years due to habitat loss and competition for resources.
Researchers will examine current level of relationship satisfaction among original participants, comparing it to their initial responses. The study aims to understand how increasing legal recognition affects gay and lesbian couples' relationships with families.
