The mile-wide open pit and 800-foot-high piles of toxic mine waste would permanently destroy thousands of acres of occupied, federally protected jaguar habitat where this jaguar lives.“The Rosemont Mine would destroy El Jefe’s home and severely hamstring recovery of jaguars in the United States,” said a prepared statement from Randy Serraglio, conservation advocate with the Center for Biological Diversity. “At ground zero for the mine is the intersection of three major wildlife corridors that are essential for jaguars moving back into the U.S. to reclaim lost territory. The Santa Rita Mountains are critically important to jaguar recovery in this country, and they must be protected.”
Conservation CATalyst and the Center for Biological Diversity released new video today of the only known wild jaguar currently in the United States.Captured on remote sensor cameras in the Santa Rita Mountains just outside of Tucson, the dramatic footage provides a glimpse of the secretive life of one of nature’s most majestic and charismatic creatures. This is the first-ever publicly released video of the #jaguar, recently named 'El Jefe' by Tucson students, and it comes at a critical point in this cat’s conservation.

By the end of the century, the season averaged growing temperature will very likely exceed the highest temperature ever recorded throughout the tropics and subtropics. By 2050, the increase in temperature alone is projected to cause a 20% reduction in the yield of all of the major grains (maize, wheat, rice and soybeans). The breadbasket countries in the midlatitudes will experience marked increases in year-to-year volatility in crop production. Increasing stresses on the major crops due to climate change, coupled with the increasing demand for food due to increasing population and development, present significant challenges to achieving global food security. This lecture explores the likely impact of climate change and volatility on food production and availability in the foreseeable future.The lectures draw a full house to Centennial Hall, so get there ahead of the 7 p.m. start time if you want a good seat.

When asked what the creepiest thing he’s encountered on the job, Kelly admitted, “Generally it has to do with the toilet.” Considering the previous horror stories we’ve heard of floating messes or broken toilets creating a vacuum seal, we’re not surprised. But he still managed to add something novel and gross to the collection: “Recently I had to clean up a gallon-sized ball of urine mixed with acid.” Why acid? It’s added to the urine to keep it from clogging the system or damaging machinery. Ew.Read the whole thing here.
Was this the face that launch'd a thousand ships,And I remember a brief scene where Faustus is showing off, using his devilish powers to perform parlor tricks for a Duke and Duchess. The Duchess asks for a dish of grapes even though it's the dead of winter. No mortal could produce fresh grapes at that time of year, but Mephistopheles leaves and returns a moment later with the fruit, which the Duchess says are "the sweetest grapes that e’er I tasted." When the Duke asks how he did it, Faustus replies, Mephistopheles sped to the far east where it was summer and brought back the grapes.
And burnt the topless towers of Ilium—
Sweet Helen, make me immortal with a kiss.
Jones, an associate professor in the University of Arizona's College of Optical Sciences and head of the Jones Research Group, knows a thing or two about lasers. And although he is a "Star Wars" fan who received a toy lightsaber for his birthday, he says laser swords are easier said than done for a couple of reasons — battery power and light physics chief among them.Jones says that battery power would also be a problem:
Curiously, although they emit light, the lightsabers in "Star Wars" aren't made of it. They are said to be made of plasma — a hot, gassy blend of ions — wrapped in a "force containment field," which is probably some kind of electromagnetic field, Jones says. He adds that the lightsaber might be better off if it were made of, well, light.
Light is made of photons, which "don't like to interact with each other," so sword fighting with light would be futile. The physics just aren't there. But, say, cutting off a hand with it? Tricky, but not impossible.
