Childhood muscular fitness and adult metabolic syndrome
About 20-25 percent of adults have the metabolic syndrome and have increased risk of developing both cardiovascular disease and type 2 diabetes. In a new longitudinal study, investigators examined associations between childhood muscular fitness (strength, endurance, and power) and metabolic syndrome -- the latter assessed once they reached adulthood.

Does physical activity lower the risk of bacterial infections?
The risk of viral infections is known to be affected by physical activity, but little information is available regarding the more serious infections caused by bacteria. In a new study, investigators examined the relationship between leisure-time physical activity and suspected bacterial infections during a one-year follow up.

Yoga may not count toward 30 minutes of daily physical activity, but may have other benefits
Hatha yoga is an increasingly popular form of physical activity and meditative practice in the U.S. It is important to understand the calorie cost and intensity of yoga in relation to the national physical activity guidelines, which generally encourage 30 minutes of moderate-intensity physical activity on most days of the week.

Team compares effectiveness of four PD-L1 tests
In a recent study, a research team compared the performance of the four available PD-L1 assay tests. They found that one of the assays failed to reveal comparable levels of PD-L1, a tumor-promoting protein, while three others revealed comparable levels.

Ice Man, Ötzi: A treacherous murder with links to Central Italy
The copper used to make Ötzi's axe blade did not come from the Alpine region as had previously been supposed, but from ore mined in southern Tuscany. Ötzi was probably not involved in working the metal himself, as the high levels of arsenic and copper found in his hair had, until now, led us to assume. His murder over 5,000 years ago seems to have been brought about due to a personal conflict a few days before his demise, and the man from the ice, despite his normal weight and active life-style, suffered from extensive vascular calcification.

Science can shape healthy city planning
The health gains achieved if cities were designed so that shops, facilities, work and public transportation were within walking distance of most residents have now been quantified by researchers. In a series of articles, researchers tackle how to implement timely research into city design, planning and policy to improve the health of a city’s residents.

How to power up graphene implants without frying cells
In the future, our health may be monitored and maintained by tiny sensors and drug dispensers, deployed within the body and made from graphene -- one of the strongest, lightest materials in the world. Graphene is composed of a single sheet of carbon atoms, linked together like razor-thin chicken wire, and its properties may be tuned in countless ways, making it a versatile material for tiny, next-generation implants.

To produce biopharmaceuticals on demand, just add water
Researchers have created tiny freeze-dried pellets that include all of the molecular machinery needed to translate DNA into proteins, which could form the basis for on-demand production of drugs and vaccines.

Landmark map reveals the genetic wiring of cellular life
A new map breaks away from the old way of studying genes one at a time, showing how genes interact in groups to shed light on the genetic roots of diseases.
