"The U.S. Supreme Court on Monday declined to take up the hotly contested issue of gay marriage, a surprise move that will allow gay men and women to marry in five states where same-sex weddings were previously banned.

By rejecting appeals in cases involving Virginia, Oklahoma, Utah, Wisconsin and Indiana, the court left intact lower-court rulings that struck down bans in those states.

Other states under the jurisdiction of appeals courts that struck down the bans will also be affected, meaning the number of states with gay marriage is likely to quickly jump from 19 to 30."===http://www.cnbc.com/id/102058024

Toyota announced the launch of a hydrogen-powered fuel-cell car in the U.S. next year on Monday at the annual Consumer Electronics Show (CES) in Las Vegas. The car, which resembles the popular Corolla, is yet to be named, but like the birth of a royal child it’s the pedigree that counts — and Toyota is the largest auto manufacturer in the world. However, unlike a royal child, hydrogen fuel-cell vehicles have been fighting an uphill battle against logistical, technological and economic odds since their inception.

“For years, the use of hydrogen gas to power an electric vehicle has been seen by many smart people as a foolish quest,” Bob Carter, senior vice president of automotive operations for Toyota Motor Sales, said at the CES event. “Yes, there are significant challenges. The first is building the vehicle at a reasonable price for many people. The second is doing what we can to help kick-start the construction of convenient hydrogen refueling infrastructure. We’re doing a good job with both and we will launch in 2015.”

Calling it the “car of the future,” Carter said the vehicle will be a zero-emission, mid-size, four-door sedan with a driving range of at least 300 miles between refueling and a fill-up time of less than five minutes. No official price tag was announced, but it is estimated that the cost will range from $50,000 to $100,000.

“We aren’t trying to re-invent the wheel; just everything necessary to make them turn,” said Carter.

Not only does this include the technology inside the car, but also the infrastructure needed for refueling.
Hydrogen-powered fuel-cell vehicles run on hydrogen gas, making them similar to battery-only models such as the Nissan Leaf that plug-in to recharge in that they emit none of the tailpipe pollution association with burning gasoline. The only exhaust on the Toyota fuel-cell vehicle will be water vapor.

“Battery models carry electricity in their lithium-ion battery packs while fuel-cell vehicles make electricity on board in a chemical reaction between hydrogen and oxygen,” Bloomberg Businessweek reported. “While hydrogen vehicles have a range comparable to gasoline vehicles and need only a few minutes to refuel — compared with hours for most battery autos — there are few hydrogen pumps currently open to the public.”

To be precise there are currently nine hydrogen refueling stations open to the public, all of them in the Los Angeles metropolitan area, and another dozen in California that are private or for demonstration. For this reason the vehicle will initially launch in California — a state known for leading the nation in emissions standards and efficiency mandates. In 2012 the California Air Resources Board required that by 2025 one in seven new cars sold be zero-emission.

California has set aside more than $200 million to build another 20 hydrogen fueling stations by 2015 with as many as 100 possible within the next decade. Toyota has partnered with UC-Irvine to help determine the best locations for these fueling stations.

Addressing concern over the sparseness of refueling opportunities, Carter said, “Stay tuned, because this infrastructure thing is going to happen.”----http://thinkprogress.org/climate/2014/01...-cell-car/

The Internet Encyclopedia of Philosophy

http://www.iep.utm.edu/

The Stanford Encyclopedia of Philosophy

http://plato.stanford.edu

These are both large projects, comprehensive encyclopedias that are being constantly updated. Authors include many prominent contemporary philosophers.

Which is better? It depends on the article, I guess. Sometimes articles on similar subjects take rather different approaches, so it can be enlightening to read what both encyclopedias have to say about the same thing.

Both encyclopedias have many articles on all aspects of the philosophy of science, as well as the philosophies of mathematics, logic, mind, language, the many philosophical problems associated with space, time, causality and quantum mechanics, and so on. No end of things that might fascinate people interested in science.

(CNN) -- "Today, the Ebola virus spreads only through direct contact with bodily fluids, such as blood and vomit. But some of the nation's top infectious disease experts worry that this deadly virus could mutate and be transmitted just by a cough or a sneeze.
"It's the single greatest concern I've ever had in my 40-year public health career," said Dr. Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota. "I can't imagine anything in my career -- and this includes HIV -- that would be more devastating to the world than a respiratory transmissible Ebola virus."
Osterholm and other experts couldn't think of another virus that has made the transition from non-airborne to airborne in humans. They say the chances are relatively small that Ebola will make that jump. But as the virus spreads, they warned, the likelihood increases.
Every time a new person gets Ebola, the virus gets another chance to mutate and develop new capabilities. Osterholm calls it "genetic roulette."
As of October 1, there have been more than 7,100 cases of Ebola, with 3,330 deaths, according to the World Health Organization, which has said the virus is spreading at a much faster rate than it was earlier in the outbreak.
Ebola is an RNA virus, which means every time it copies itself, it makes one or two mutations. Many of those mutations mean nothing, but some of them might be able to change the way the virus behaves inside the human body.
"Imagine every time you copy an essay, you change a word or two. Eventually, it's going to change the meaning of the essay," said Dr. C.J. Peters, one of the heroes featured in "The Hot Zone."====http://www.cnn.com/2014/09/12/health/ebola-airborne/
