Loss of Muscle Strength and Mass Slower Walking Speed in Older

In a new research, scientists have identified that older people walk at a slower speed and tire more quickly because of loss of strength and mass in leg muscles. Using computer simulations the team found that these physiological changes explain the slower walking speed preferred by the elderly, and that a focus on building up these leg muscles may be the only effective way to improve elderly walking. The study findings published in The Journal of Physiology.

Link between Bariatric Surgery and Heart Disease Risk

According to a new study published in Pediatrics, adolescents with severe obesity who had bariatric surgery showed significant improvements in cardiovascular disease risk factors. Before bariatric surgery, 335 of the study participants had three or more defined cardiovascular disease risk factors. However, three years post-surgery only 5% of study participants had three or more risk factors; representing significant reduction in the overall likelihood of developing cardiovascular disease later in life.

Tubeworm Produces Ferritin More Efficiently

In a new study published in Biochemical Journal, researchers have discovered with potential human health impacts in a parchment tubeworm, the marine invertebrate Chaetopterus sp., and found that the tubeworm have a ferritin with the fastest catalytic performance ever described, nearly eight times faster than that of human capabilities.

Brain MRI and AI could Help Children with Hearing Loss

A new study, published in the journal Proceedings of the National Academy of Sciences, described a machine learning algorithm that uses brain scans to predict language ability in deaf children after they receive a cochlear implant. This study's novel use of MRI and artificial intelligence to understand brain structure underlying language development has broad-reaching implications for children with developmental challenges.

Novel Tuberculosis Vaccine Offers Better Protection

A unique platform that resulted in a promising HIV vaccine has also led to a new, highly effective vaccine against tuberculosis that is moving toward testing in humans. The new vaccine completely protected 41% and reduced overall TB disease by 68% in vaccinated rhesus macaques, according to a study published as an Advanced Online Publication of Nature Medicine.
