A team of Virginia Tech researchers have discovered fossils of kinorhynch worms - commonly known as mud dragons - dating back more than 530 million years.

The historic find - made in South China - fills a huge gap in the known fossil record of kinorhynchs, small invertebrate animals that are related to arthropods, featuring exoskeletons and segmented bodies, but not jointed legs.

The first specimen was unearthed in rocks in Nanjiang, China, in 2013 and more fossils were found later that year and in 2014.

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.

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.

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.
