The liver receptor homolog-1 (Lrh-1) molecule first shown to function in the liver plays a crucial role in pregnancy in mice and has a key role in the human menstrual cycle, according to researchers at the University of Montreal. 

Mice that were genetically engineered not to produce Lrh-1 were unable to create the uterine conditions necessary for establishing and sustaining pregnancy, resulting in the formation of defective placentas. The researchers then showed that Lhr-1 was present in the human uterus and the essential processes related to the success of early gestation. 

India and China were both exempt from restrictions in the Kyoto agreements, because they were considered emerging economies. For that reason, while western nations have reduced their carbon footprints, CO2 emissions worldwide have continued upward.

It's hard to tell people in developing nations that they have to stop progress and can't have air conditioners and will not enjoy things developed nations already have.

Resverlogix Corp. has announced that its Phase 2b ASSURE clinical trial evaluating RVX-208 in high-risk cardiovascular patients with low high-density lipoprotein (HDL) did not meet its primary endpoint of a -0.6% change in percent atheroma volume as determined by intravascular ultrasound (IVUS). The RVX-208 treated group had -0.4% plaque regression (p= 0.08).

Crystal Solar has completed a U.S. Department of Energy (DOE) funded Incubator project regarding technology development and manufacturing cost-effectiveness of epitaxial solar cells and modules. Thin epitaxial silicon solar cell  technology has the capability to improve the way silicon is made by eliminating many steps in the current process flow while retaining the high efficiency of mono-crystalline silicon.  

They estimate this could result in reduction of module costs by approximately 50% from today's levels to ~$0.40/W, enabling the cost of solar power to become comparable to existing energy costs in most parts of the world.  

Is kite power economically viable in the 21st century?

We'll find out. The TwingKite,  based on Empa's Tensairity technology, is set to take flight thanks to a  “Venture Kick” jury that is providing 10,000 Swiss Francs in support.

A kite, a reel and a console are the components of this new method for making electricity from wind. Rather than going up a hundred meters, like legacy wind efforts, TwingKite will go up to 300.

As narratives of modern “hook-up” culture in young people take center stage in popular media, behavioral researchers are starting to ask what psychological consequences, if any, may be in store for young adults who engage in casual sex.

A new survey found higher levels of general anxiety, social anxiety, and depression among students who recently had casual sex.
