by CORDIS Credit: Anshuman Rath, Shutterstock The membrane attack complex (MAC) is a set of proteins typically formed on the surface of pathogen cell membranes. They punch tiny holes in an invading bacteria’s membrane. The bacteria ultimately dies if enough holes are punched. When an invader is discovered, our immune system produces many MACs. Those...
New target may help protect bones as we age
by Medical College of Georgia at Augusta University Dr. Meghan McGee-Lawrence. Credit: Michael Holahan, Augusta University Drugs we take like prednisone can weaken our bones and so can aging, and scientists working to prevent both have some of the first evidence that the best target may not be the logical one. They are finding that...
Five years of high-dose vitamin D did not affect incidence of cardiovascular disease or cancer
by University of Eastern Finland Credit: CC0 Public Domain A trial by the University of Eastern Finland found that taking a much higher dose of vitamin D than recommended for five years did not affect total mortality or the incidence of cardiovascular disease or cancer in older men and women. In population studies, low levels...

Study in mice finds erectile dysfunction medication worsened abdominal aortic aneurysms
by American Heart Association Credit: Unsplash/CC0 Public Domain In a laboratory study in mice, sildenafil, a commonly used erectile dysfunction medication, was found to worsen abdominal aortic aneurysms, indicating additional research may be needed to determine if the medication may have the same effect on people, according to new research published today in the Journal of...
Prescription drug misuse later in life greatly increases risk for substance use disorder
by University of Michigan Credit: Unsplash/CC0 Public Domain Nearly half of people in a large U.S. study reported misusing prescription drugs between ages 18-50, which made them more likely to develop substance use disorder symptoms as adults––especially those whose misuse peaked later in life. The new study from University of Michigan School of Nursing researchers...
Researchers shed new light on damaging effects of standard heart attack treatment
by Indiana University School of Medicine Credit: Pixabay/CC0 Public Domain A study led by Indiana University School of Medicine is challenging standard treatment methods used to prevent muscle damage during heart attack. In a paper published in the Journal of the American College of Cardiology, Rohan Dharmakumar, Ph.D. asserts that a common treatment given to patients experiencing heart attack may...
Adult epilepsy treatment reduces seizures in children
RUTGERS UNIVERSITY A surgical treatment commonly used to reduce epileptic seizures in adults also is effective and safe for children, according to a Rutgers study. The study, published in the journal Neurosurgery, is one of the first to investigate responsive neurostimulation system (RNS)—a device similar to a pacemaker that sends electric charges to the heart, which delivers...
“Deepfaking the Mind” Could Improve Brain-Computer Interfaces for People with Disabilities
Synthetic neurological data created using generative adversarial networks could speed up training of brain-computer interfaces, new study finds. Researchers at the USC Viterbi School of Engineering are using generative adversarial networks (GANs) — technology best known for creating deepfake videos and photorealistic human faces — to improve brain-computer interfaces for people with disabilities. In a paper...
Experimental Gene Therapy Reverses Sickle Cell Disease for Years
A study of an investigational gene therapy for sickle cell disease has found that a single dose restored blood cells to their normal shape and eliminated the most serious complication of the disease for at least three years in some patients. Four patients at Columbia University Irving Medical Center/NewYork-Presbyterian participated in the multicenter study, the first to...
