Russia has banned the shipment of medical specimens abroad, threatening hundreds of patients and complicating drug trials by major companies, the national Kommersant newspaper reported on Wednesday.
Kommersant attributed the ban to fears in the secret service that Russian genetic material could be used abroad to make biochemical weapons targeting Russians. The quality daily cited anonymous sources in the medical community.

Remember a few years ago when we reported a shark that was born to a virgin mother? Here’s an update:
Scientists have solved the mystery of how a baby shark appeared in a tank of females without the help of a male: it was a virgin birth. The bonnethead shark was born through “parthenogenesis”, a process where an egg develops into an embryo without being fertilised by sperm.
Virgin births, possible in some birds, amphibians, reptiles and bony fishes, are extremely rare. It had never before been confirmed in cartilaginous fish, such as sharks and rays. The birth, in 2001, astonished scientists as placental animals, including this shark, were thought to need genetic material from sperm and egg to produce viable young.

Researchers at Harvard University and Princeton University have made a crucial step toward building biological computers, tiny implantable devices that can monitor the activities and characteristics of human cells. The information provided by these “molecular doctors,” constructed entirely of DNA, RNA, and proteins, could eventually revolutionize medicine by directing therapies only to diseased cells or tissues.
