Scientists have found that those who run barefoot, or in minimal footwear, tend to avoid “heel-striking,” and instead land on the ball of the foot or the middle of the foot. In so doing, these runners use the architecture of the foot and leg and some clever Newtonian physics to avoid hurtful and potentially damaging [...]
Most people know that exercise protects against heart attack and stroke, but researchers have spent 30 years unraveling the biochemistry behind the idea. Researchers have now revealed new details of how athletic hearts push blood through arteries with greater force and the force-sensitive chain reaction that protects arteries.

It has been thought that young fish, lacking well-developed hearing organs, could not perceive the sounds made by their larger, older relatives. Now, researchers have used a combined fish tank and sound-proof chamber to show for the first time that catfish of all ages can communicate with one another.

Magnetic resonance spectroscopy — which analyzes the biochemistry rather than the structure of tissues — may someday be able both to pinpoint the precise location of prostate cancer and to determine the tumor’s aggressiveness, information that could help guide treatment planning. Researchers report how spectroscopic analysis of the biochemical makeup of prostate glands accurately identified [...]
A new study found that UV-blocking contact lenses can reduce or eliminate the effects of the sun’s harmful UV radiation.
Is it possible that directed prayer might spark forgiveness in those doing the praying — and in the process preserve relationships?

Decaying corpses are usually the domain of forensic scientists, but palaeontologists have discovered that studying rotting fish sheds new light on our earliest ancestry.
Bone marrow is a leading source of adult stem cells, which are increasingly used for research and therapeutic interventions, but extracting the cells is an arduous and often painful process. Now, researchers have found evidence that fat tissue, known as adipose tissue, may be a promising new source of valuable and easy-to-obtain regenerative cells called [...]

The human brain is a delicate organ, robustly defended. A thick skull shields it from any direct exposure to the outside world, and the blood-brain barrier keeps out any foreign substances that are circulating within. New research shows that the brain may have its own specialized immune defenses, too.
Researchers have determined that patients with nonalcoholic fatty liver disease have a higher overall mortality rate compared with the general population.
