A pair of socks embedded with miniaturized microbial fuel cells and fueled with urine pumped by the wearer's footsteps has powered a wireless transmitter to send a signal to a PC., the first self-sufficient system powered by a wearable energy generator based on microbial fuel cell technology. 

The birth rate is declining in all industrialised countries, and socioeconomic factors and women's age are not solely to blame. Male reproductive health and environmental factors are also significant, as concluded in a new scientific review article. The article was recently published in the prestigious American journal Physiological Reviews.

Behind the article are fertility researchers from Denmark, the US and Finland. The researchers studied a number of factors related to fertility, and one of the main conclusions of their study was that poor semen quality contributed to increases in infertility and the use of assisted reproductive technology.

37% percent of online adults say that health and medicine is among the topics they find most interesting, while 32% identify science and technology in their top three, according to a 

The developed world loves to put on food drives, places to donate canned goods to the needy. It is an easy feel-good thing to do. But it may be unnecessary, according to findings in The European Journal of Public Health.

Too many tests at the doctor's office could cost you more than just dollars. In addition to the huge hit to your wallet, there's also the potential harm of false positives, and just because a test has traditionally been done for a condition doesn't mean it's the best way to treat it.

U-M neurologist Brian Callaghan, M.D., M.S., is helping lead a national push to determine what neurologic tests or services are performed more than they should be.

Scientists and teachers have combined to develop a simple spreadsheet-based method of teaching aerodynamic drag to 14 and 15 year olds. By measuring the speed of one of their classmates riding a bike and taking a photo in order to measure the frontal area of the cyclist, the students were able to calculate the drag co-efficient.

The results are published today, 11th December 2015, in the journal Physics Education.
