Research reveals that nectar robbing by bumble bees reduces pollen transfer and pollination success in the scarlet gilia plant. The study found that high robbing rates attract fewer pollinators, leading to decreased reproductive success.
Scientists at Pacific Northwest National Laboratory have created a new method to produce valuable industrial enzymes in plants, reducing costs and increasing efficiency. The process uses transgenic potato plants to generate cellulase enzymes, which can be used in various applications, including food processing and pharmaceuticals.
A study found that higher education levels are associated with more severe brain shrinkage in older adults, yet this does not lead to significant memory loss or cognitive impairment. The 'reserve hypothesis' suggests that education provides a protective effect against age-related mental decline.
A study found that African dust is a major factor affecting southeast U.S. air quality, with up to half of breathable particles in the air originating from Africa. The dust can push total airborne particles above the EPA's Clean Air Act limit on certain days.
A Massachusetts General Hospital study reveals that a majority of patients with unpaid bills were poor enough to qualify for state-sponsored free care or Medicaid. The study found that 84% of free-care patients and 78% of emergency bad debt patients had incomes below the federal poverty level.
A nationwide study is being launched in six US cities to determine the most effective HIV prevention counseling program. The study, called EXPLORE, will compare two behavior interventions: standard risk reduction counseling and a client-centered approach that focuses on personal decision-making.
Researchers have produced two blood factors that treat most patients with blood clotting disorders. The production of human blood proteins in plants eliminates disease transmission risk, making lifesaving treatments more accessible. This technology is expected to be 10 times cheaper than current methods and provides a stable production...
