PROVIDENCE R.I. [Brown University] -- Researchers have used ultra-high-speed x-ray pulses to make a high-resolution "movie" of a molecule undergoing structural motions. The research, published in Nature Chemistry, reveals the dynamics of the processes in unprecedented detail -- capturing the excitation of a single electron in the molecule.

URBANA, Ill. - A corn gene identified from a 118-year-old experiment at the University of Illinois could boost yields of today's elite hybrids with no added inputs. The gene, identified in a recent Plant Biotechnology Journal study, controls a critical piece of senescence, or seasonal die-back, in corn. When the gene is turned off, field-grown elite hybrids yielded 4.6 bushels more per acre on average than standard plants.
Virtually every day, millions of children and adolescents are being bombarded by sexually explicit direct-to-consumer advertising, despite pharmaceutical CEOs' claims to the contrary.
BOSTON, MA - Patients over age 50 who underwent an all inside arthroscopic repair technique had lower rates of subsequent total knee surgery than a similar group that was only observed, according to research presented at the American Orthopedic Society of Sports Medicine Annual Meeting today.
Dr. Jason L. Dragoo from Stanford Medicine in Redwood City, Calif., and his team of researchers followed 48 patients over age 50 who were diagnosed with a meniscal root tear. The meniscus is the spongy cartilage that provides cushion in the knee.
Chaco Canyon, a site that was once central to the lives of pre-colonial peoples called Anasazi, may not have been able to produce enough food to sustain thousands of residents, according to new research. The results could shed doubt on estimates of how many people were able to live in the region year-round.
MINNEAPOLIS - A new study has found that mentally stimulating activities like using a computer, playing games, crafting and participating in social activities are linked to a lower risk or delay of age-related memory loss called mild cognitive impairment, and that the timing and number of these activities may also play a role. The study is published in the July 10, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology.
What if the missing 'environmental' factor in some of our deadliest neurological diseases were really written in our genome?
Writing in Frontiers in Genetics, researchers from the University of Dusseldorf explain how viruses ended up in our DNA - and what puts them in the frame in unsolved diseases like multiple sclerosis.

Citrus fruits, coffee and avocados: The food on our tables has become more diverse in recent decades. However, global agriculture does not reflect this trend. Monocultures are increasing worldwide, taking up more land than ever. At the same time, many of the crops being grown rely on pollination by insects and other animals. This puts food security at increased risk, as a team of researchers with help from Martin Luther University Halle-Wittenberg (MLU) writes in the journal Global Change Biology.
A multinational team of researchers has identified countries where agriculture's increasing dependence on pollination, coupled with a lack of crop diversity, may threaten food security and economic stability. The study, which was published in the journal Global Change Biology on July 11, 2019, is the first global assessment of the relationship between trends in crop diversity and agricultural dependence on pollinators.
When new rules capped training hours for medical residents at 80 hours per week in 2003, critics worried that the change would leave physicians-in-training unprepared for the challenges of independent practice.
Now, new research published July 11 in BMJ and led by scientists in the Department of Health Care Policy in the Blavatnik Institute at Harvard Medical School, shows that these dire warnings were largely unjustified.
An epigenetic change, a form of DNA control, that deactivates some genes linked to cancer late in human development has been conserved for more than 400 million years, new research led by the Garvan Institute of Medical Research suggests.
EPFL scientists have created the first world map of regions with the highest prevalence of the hepatitis E virus (HEV). They hope that their map - freely available online - will help governments and NGOs design more effective prevention campaigns based on reliable data, particularly when it comes to setting up refugee camps. The scientists' research has just been published in Scientific Reports.
COLUMBUS, Ohio - Many parents, potential players and medical providers are increasingly wary of youth contact sports participation. The concern over the potential short- and long-term effects of head impacts experienced by youth football players has likely driven decreasing participation, according to a group of researchers.
A newly described form of stress called chromatin architectural defect, or chromatin stress, triggers in cells a response that leads to a longer life. Researchers at Baylor College of Medicine and the Houston Methodist Research Institute report in the journal Science Advances that moderate chromatin stress levels set off a stress response in yeast, the tiny laboratory worm C. elegans, the fruit fly and mouse embryonic stem cells, and in yeast and C. elegans the response promotes longevity.
