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.

At least twice a year, Earth comes between the sun and the moon. The result is a lunar eclipse, where we see the splendid sight of Earth’s shadow falling across the moon.

In last month’s review of Preparing the Ghost, I mentioned that you can actually learn facts from some fiction. Below is one such novel, crammed with science. As author Ryan Lockwood wrote in an e-mail, “Hopefully, most of the biology described in the book is in-line with real-world scientific data. I want to educate readers to some extent and encourage them to learn more after they finish the book.”

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.
