A new study from England warns women that wearing high-heels for long periods of time can cause calf muscles to stiffen and thicken permanently. Switching to flats then makes those muscles stretch painfully. Instead, women should wear heels and flats on alternate days:
"In the study, published in the Journal of Experimental Biology, two groups of women aged between 20 to 50 years were tested. One group regularly wore high heels of two inches or more for two or more years, while the other group had always wore flats.
"The high heel wearers, who complained of discomfort when they switched to flats, were found to have muscle fibers 13 percent shorter than the women in flats."
Doctors at the National Institute of Allergy and Infectious Diseases are developing a “universal” shot to protect against every strain of flu. Trials are underway and the vaccine may be available in a few years:
"Doctors at the National Institute of Allergy and Infectious Diseases (NIAID) in Maryland developed the two-stage flu jab to fight off all strains of influenza for decades, putting an end to the current practice of yearly immunizations.
"The study, published in Science Express, said mice, ferrets and monkeys were first injected with a vaccine made from a flu virus’ DNA. They then received a “booster” dose of a regular seasonal flu vaccine."
Computer-use may make you crave chocolate. Researchers believe mental stress triggers changes in blood sugar and hormone levels that trick the brain into thinking it has worked off calories that need to be replaced:
"Researcher Jean-Philippe Chaput suggests that office workers who want to keep trim should take regular screen breaks and even consider typing while standing up.
"Dr. Chaput, of the University of Copenhagen, started to research the subject after noticing how his supervisor regularly snacked on chocolate biscuits when doing computer work."
