Obesity and heart disease
by DeeDee Stiepan, Mayo Clinic Credit: Pixabay/CC0 Public Domain It’s long been known that being overweight or obese can make a person more apt to develop conditions like high blood pressure or diabetes, which can lead to cardiovascular disease. But experts at Mayo Clinic say obesity also can affect the heart in entirely independent ways....
Exercise more effective than medicines to manage mental health, says study
by University of South Australia Credit: Unsplash/CC0 Public Domain University of South Australia researchers are calling for exercise to be a mainstay approach for managing depression as a new study shows that physical activity is 1.5 times more effective than counseling or the leading medications. Published in the British Journal of Sports Medicine, the review is the most...

Cancer is a leading cause of illness and...
Severe herpesvirus infection beats adult T-cell leukemia/lymphoma
by Impact Journals LLC Credit: Pixabay/CC0 Public Domain In a recently published editorial in the journal Genes & Cancer, researcher Tatsuro Jo from the Japanese Red Cross Nagasaki Genbaku Hospital’s Department of Hematology discussed aggressive type adult T-cell leukemia/lymphoma (ATLL). ATLL caused by human T-cell lymphotropic virus type 1 (HTLV-1) infection is associated with dismal survival...
The antibodies from camels and sharks that could change medicine
by Christina Szalinski, Knowable Magazine Full-size antibodies, like those of humans (left), typically have heavy protein chains (dark blue) and light protein chains (light blue). In addition to these standard antibodies, sharks and camels and their relatives make antibodies with only heavy chains (middle and right). The fragments at the antibody tips (shown in circles),...
New link between fatal muscle wasting disease gene and cancer discovered
by University of Portsmouth Credit: Unsplash/CC0 Public Domain Mutations of the gene encoding dystrophins have long been known to cause the debilitating muscle-wasting disease Duchenne muscular dystrophy (DMD), which affects one in every 5,000 children born, mostly boys. People with the condition will usually only live into their 20s or 30s. Now, a study, led...
Studying brain oscillations to understand what makes a memory stick
by Columbia University Recordings revealed that the coordination of electricophysiological oscillations between two brain regions (hippocampus and parietal cortex) plays a key role in solidifying long-term memories and differs from the oscillations primarily involved in creating initial memories. The image shows a sample recording. Credit: Columbia University Neuroscientists know that what makes a memory really...
Scientists make stunning discovery, find new protein activity in telomeres
by University of North Carolina Health Care Newly discovered telomeric protein VR, (green spheres) is seen accumulating in nuclei (blue ovals) in human osteosarcoma cancer cells stained in red. Credit: Griffith Lab, UNC Lineberger Once thought incapable of encoding proteins due to their simple monotonous repetitions of DNA, tiny telomeres at the tips of our chromosomes...
More Evidence for Epstein-Barr Virus’ Role in MS
Jim Kling November 08, 2022 Epstein-Barr Virus (EBV) is a suspect in the development of multiple sclerosis (MS), and recent research developments have strengthened that connection. In 2022, two studies received quite a bit of attention. One showed that EBV seroconversion occurs in the years prior to MS diagnosis in virtually every patient, and that serum levels of the neuronal damage...
