Isamu Akasaki, Hiroshi Amano and Shuji Nakamura have been award the 2014 Nobel Prize in Physics "for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources". Using blue LEDs, white light can be created in a new way and that means LED lamps, which are longer-lasting and more efficient than incandescent sources.

Sodium is back in the health concern cycle and an analysis of data in the federal nationwide dietary intake survey known as "What We Eat in America NHANES 2009-2010," has led a team of Department of Agriculture (USDA) to conclude that, on any given day 49 percent of U.S. adults eat at least one sandwich, and sandwiches account for 20 percent of total daily sodium intake. 

No one is seriously expecting to overturn Einstein's idea of time dilation, and instead the goal is often to find the possible limits. That means looking for deviations in experiments with increasing precision or under extreme conditions. 

Seven Swedish women have had embryos reintroduced after receiving wombs from living donors and now one has delivered a healthy and normally developed boy, reveals the case study in The Lancet.

The uterus transplantation research project at the University of Gothenburg started in 1999 and the goal has been to enable women who were born without a womb or who have lost their wombs in cancer surgery to give birth to their own children.

Nine women in the project have received a womb from live donors – in most cases the recipient's mother but also other family members and close friends. The transplanted uterus was removed in two cases, in one case due to a serious infection and in the other due to blood clots in the transplanted blood vessels.

Cerebral palsy is the most common motor disability in childhood, afflicting between between 1 and 4 per 1,000 kids born worldwide. It's more common among boys than girls and only about half of adolescents with it can walk independently but regardless of that, kids with cerbral palsy rate their quality of life pretty high.

Either adolescents with cerebral palsy are doing pretty well or able-bodied adolescents in general invent problems when they have none. 

Researchers are investigating a possible association between breast implants and a form of lymphoma that may develop tumors at a later stage. The researchers conclude that breast implants can cause a new subtype of the rare yet malignant lymphoma known as anaplastic large cell lymphoma (ALCL).

Worldwide there have been 71 documented cases of patients with ALCL in which researchers suspected breast implants to be the cause. ALCL is normally found in the lymph nodes, as well as in skin, lung, liver and soft tissue, but not usually in the breast.
