High-performance swimsuit developed: 2.4% faster swimming with the dolphin kick20 de Novembro de 2015
Researchers have succeeded in developing a new high-performance swimsuit with a “kick assist system” that improves the power of the dolphin kick. High-speed swimsuits, which made their appearance at the 2008 Olympics in Beijing, were the driving force behind a barrage of new world records. However, the International Swimming Federation changed the rules significantly in 2010 due to a concern that swimming races were not being won by superior swimming techniques but by superior swimsuits, and the ruling body imposed strict regulations. These restrictions greatly narrowed the scope of swimsuit development and all but eliminated hope for improving swimsuit performance. To make a breakthrough under these conditions, the research group went back to the drawing board and put their heads together to figure out what exactly about a swimsuit allows a swimmer to go faster.

Exercise slows tumor growth, improves chemotherapy in mouse cancers22 de Março de 2015
One way many cancers grow resistant to treatment is by generating a web of blood vessels that are so jumbled they fail to provide adequate oxygen to the tumor. With oxygen starvation, the tumor gains a sort of cloaking device that protects it from the toxic effects of chemotherapy drugs and radiation, which are designed to seek out well-oxygenated tissue. Researchers have long tested various approaches to improving blood flow to the tumor in the hopes of restoring potency to treatments, however, to date, not much has shown promise.
