The real reason your breasts are itchy

Skin is the human body’s largest organ, and with all that real estate — some 22 square feet of it on the average adult — exposed to sun, countless irritants, and allergens, it’s bound to get a little itchy sometimes (via National Geographic). If that urge to scratch is on your leg or your arm, no […]

High blood pressure symptoms: Do your ankles look like this? Warning sign of hypertension

High blood pressure is also known as hypertension. Hypertension occurs when your blood pressure rises and stays above normal over a long period of time. Hypertension is often related to atherosclerosis, which is the build-up of plaque in blood vessels, often associated with an increase in a person’s “bad” cholesterol. This condition can also lead […]

Sweden uncovers 3,700 false positives from COVID-19 test kit

Sweden’s Public Health Agency said Tuesday a faulty test kit had returned some 3,700 false positive results, an error discovered by two laboratories during routine quality controls. The agency said the PCR kits, which test for an ongoing COVID-19 infection, were made in China by the company BGI Genomics and had been distributed worldwide. In […]

Chemicals in e-cigarettes 'damage cells in lungs and blood vessels'

Chemicals in e-cigarettes mix to form entirely new combinations that are toxic to lung cells and blood vessels, scientists discover Researchers tested the effects of vaping chemicals on human cells in lab tests They found when the chemicals mixed they became unstable and harmful Study adds to growing evidence that e-cigarettes are not safe or […]

Antibiotic resistance linked to soil pollution

New research has identified an association between heavy metal and radioactive soil pollution and the antibacterial resistance of bacteria living in that soil. The research, which appears in the journal Microbial Biotechnology, adds weight to earlier findings. Indeed, previous research suggests that because bacteria adapt to heavy metal and radioactive pollution, they also develop antibacterial […]

WHO Europe chief cites coronavirus warning signs ahead

The World Health Organization’s top official in Europe warned Thursday that the coronavirus is a “tornado with a long tail” and said rising case counts among young people could ultimately spread to more vulnerable older people—and cause an uptick in deaths. Dr. Hans Kluge said younger people are likely to come into closer contact with […]

Weak electric currents could help combat superbugs

Scientists have shown that currents measured in millionths of an amp kill bacteria by disrupting their outer membranes. The finding may inspire new antimicrobial technologies that use electricity to slow the spread of antibiotic resistant infections. Scientists have known since the 1960s that electricity can kill or suppress the growth of bacteria. The increasing threat […]

Antibody study suggests more lasting immunity against COVID than believed

(HealthDay)—In a finding that should encourage scientists who are racing to develop coronavirus vaccines, a new study out of Iceland suggests that immunity to the disease may not be as fleeting as first thought. Among 30,000 Icelandic residents who were tested for antibodies to COVID-19, researchers discovered the antibodies stayed in people’s systems for at […]
