This pointy-nosed shrew, a new fossil find from China, may be the earliest grandmother of all placental mammals, scientists report in a new study. Or perhaps she is the oldest great-aunt. Either way, it’s another big find this week in paleontology.
For the first time, doctors have imaged a live birth using a special MRI machine, hoping to illuminate the birthing process and understand how complications may develop. The mother and baby — who was born Nov. 20 — are both doing fine, according to doctors at Berlin's Charité hospital, who announced the results today.
Cryopreservation was once the domain of sci-fi novels and B-rate movies. (Think Encino Man.) But it’s increasingly real, as the recent birth of a healthy boy from a frozen embryo created 20 years earlier shows.
The birth, which is reported in a study in the online edition of the journal Fertility and Sterility, sets a record. Until now, no embryo frozen for this long has resulted in a live birth.

Rajo Devi Lohan gave birth to her daughter at age 70. Now, 18 months later, she is dying of old age.
Rajo, a poor villager in northern India, gave birth to daughter Naveen a year and a half ago after undergoing in-vitro fertilization, reports FOX News. She and her husband Balla took out $3,000 in loans for the procedure. Rajo's womb ruptured during the Caesarean birth, however. And now, her child barely walking, she is bedridden.
Even though the combination of affluence and fertility drugs has raised the age at which many women give birth, children born to older women continue to suffer a disproportionately high rate of birth defects and genetic disease. Many of these problems result from the degradation of the area of the region of the egg around the nucleus.
To correct for those problems, a team of Japanese researchers has implanted the nucleus of an older woman's egg into the egg cell of a younger donor. This may fix the problem, but it also moves medicine closer to the ethically challenging creation of a person with three biological parents.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
