Why strength depends on more than muscle

A recent study from the University of Nebraska-Lincoln has given new meaning to the concept of brain power by suggesting that physical strength might stem as much from exercising the nervous system as the muscles it controls. Over the past few years, researchers have found evidence that lifting more repetitions of lighter weight can build...

Large-scale study of adaptation in yeast could help explain the evolution of cancer

Genes provide instructions to cells in the body telling them what to do and not do in order to function optimally. Small changes in genes, called mutations, can have major consequences. Similar to a glitch in a computer's coding, a glitch in gene coding can cause a cell's system to go haywire. Not all...

Skin vaccination with microneedle patch, influenza fusion protein improves efficacy of flu vaccines

A boosting skin vaccination with a biodegradable microneedle patch and protein constructed from sequences of influenza virus subtypes could improve the effectiveness of conventional influenza vaccines, according to a study led by Georgia State University. To increase the protection offered by standard influenza vaccines, Dr. Baozhong Wang's group made a fusion protein (4M2e-tFliC) with four...

New supplement can repair, rejuvenate muscles in older adults

Whey protein supplements aren't just for gym buffs according to new research from McMaster University. When taken on a regular basis, a combination of these and other ingredients in a ready-to-drink formula have been found to greatly improve the physical strength of a growing cohort: senior citizens.

Melanin-linked skin conditions: Breakthrough

Spots resulting from too much sun exposure and other effects of dysfunctional melanin production may become a thing of the past. Scientists have solved the structure of one of the three enzymes that generate melanin in humans, opening doors to the design of whitening compounds to remove discolorations of the skin. Summer is often a...
