A review of studies in which women rated emotional distress before treatment showed no link between stress and failure to conceive.Nicholas Bakalar
Taking it a step further, the researchers created a new mouse model with a mutated version of the gene, Gcn5, which allows investigators to closely track the defects in sperm from the early stages of sperm development through fertilization and on. This is an important step forward as it coul...
In 2018, the group succeeded for the first time in making immature human eggsfrom scratch. But the process wasn’t very efficient and it involved incubating the human stem cells in mini-ovaries they’d created in the lab from mouse embryonic cells — a resource-intensive process not exactly ...
The researchers created a SMART vaccinia virus that replicates normally to induce protection, but can be turned off in response to antibiotics if the person who has been vaccinated develops complications that are serious enough to require intervention. "We basically made the virus susceptible to antib...
Diverted drainage, due to increased stormwater runoff and heavy rainfall events above a public road in Southeast British Columbia, Canada, caused a landslide in February 2002 (Figure A). The increased velocity of this stormwater runoff created a deep vertical scar on the downstream end of the cul...
Birth defect rates vary depending on fertility treatment: study; researchers not sure if technology or biology is the cause.(Report)Reinberg, Steven
