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. 

What can be logically prior, what must be assumed, what is the metaphysically necessary apriori starting point? Here I present the one necessary before I can focus on understanding time in order to derive Einstein locality. These are crucial steps in rendering quantum mechanics naturally expected,^[1,2] which is the only interesting aim, because Einstein’s relativity alone easily emerges from classical substrates^[4], while the apparent non-locality of quantum mechanics cannot; well, except via brain-in-vat/The Matrix scenarios, but that just underlines how quantum mechanics indeed relates directly to the apriori conditions of phenomena.

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).

I have wanted to comment for some time about a number of available “theories of truth.” The occasion has now been presented by the fact that I am writing the fourth chapter of my new book (on whether and how philosophy makes progress, forthcoming from Chicago Press), which is about the surprisingly not-so-straightforward concept of progress (and truth) in science itself, the very discipline normally held to be the paragon of a truth seeking enterprise.

We posted a new preprint from the lab on arXiv and would love your comments.

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.

Hockey moves fast. As efforts to track the puck visually showed, it can be dizzying to keep track of things in a small field of view like a television.

Analyzing games and plays means manual work, for that reason. But Disney Research, located in Pittsburgh and Zurich, have developed an automated technique for analyzing the patterns of play of field hockey teams, providing a new tool for coaches and commentators who must make sense of mountains of video and other game data.
