An easy-to-use implant sensor for at-home glaucoma monitoring developed by researchers at Caltech and tested at UC San Francisco could significantly benefit patients by providing convenient, on-demand self-monitoring and physicians by more effectively tailoring individual treatments. “Sensors based on nanostructures on a transparent butterfly wing may one day help preserve […]

Researchers at the University of Tokyo uncovered the molecular mechanism driving the activation of a human cancer-causing protein by the CagA pathogenic effector in Helicobacter pylori bacterial strains prevalent in Japan and other East Asian countries, which underlie the higher rate of gastric cancer onset in these regions compared to other parts […]

MIT biologists have discovered a function of a gene that is believed to account for up to 40 percent of all familial cases of amyotrophic lateral sclerosis (ALS). Studies of ALS patients have shown that an abnormally expanded region of DNA in a specific region of this gene can cause […]

An international team of researchers from NASA Ames Research Center, Environmental and Radiation Health Sciences Directorate at Health Canada, Oxford University, Canadian Nuclear Laboratories, Belgian Nuclear Research Centre, Insilico Medicine, the Biogerontology Research Center, Boston University, Johns Hopkins University, University of Lethbridge, Ghent University, Center for Healthy Aging and many […]

Automated breast-density evaluation was just as accurate in predicting women’s risk of breast cancer, found and not found by mammography, as subjective evaluation done by radiologists, in a study led by researchers at UC San Francisco and Mayo Clinic. Both assessment methods were equally accurate in predicting both the risk […]

Researchers have known for a couple of decades that early life adversity can affect the way that particular genes function through a process called epigenetics – a bit like a dimmer switch on a light, pushing gene activity up or down. What they haven’t been able to show until now […]

Physicians and patients need more guidance to help them navigate the complex array of clinical factors and personal preferences that must be considered when deciding how best to individualize their approach to breast cancer mammography screening. What makes the choice even more complicated is that the benefits of the screening […]

Our cerebral cortex, a sheet of neurons, connections and circuits, comprises “ancient” regions such as the hippocampus and “new” areas such as the six-layered “neocortex”, found only in mammals and most prominently in humans. But when in evolution did the components of cerebral cortex arise and how did they evolve? […]

As people age, their intestinal stem cells begin to lose their ability to regenerate. These stem cells are the source for all new intestinal cells, so this decline can make it more difficult to recover from gastrointestinal infections or other conditions that affect the intestine. This age-related loss of stem […]

Among more than 230,000 cardiac patients who had sustained a heart attack or undergone one of two common heart procedures, only 16 percent participated in a formal exercise program after their hospitalization – despite the program’s demonstrated benefits to health. The finding is published in the print journal Circulation. Lead investigator Alexis Beatty, a […]

When biomedical engineering students Genevieve Goelz, Maria Fernanda Larraga Martinez, Anna Rodriguez, and Ashten Sherman teamed up for their senior design course in September 2017 to find a solution to lymphedema in breast cancer patients, they didn’t know a lot about each other or the medical condition they were tapped […]

Depression is a debilitating condition, significantly reducing the quality of life and oftentimes ending with death. Scientists have been trying to improve depression therapy, but so far results have been limited. But now researchers from The Black Dog Institute, UNSW Sydney and Western Sydney University conducted an international study, which […]
