The best way to make hydrogen fuel is thought to be photo electrochemical, a process for water splitting. When the sun hits, the solar energy is absorbed in a cell used for splitting water molecules into hydrogen and oxygen.
Progress in the technology, however, has been limited by the lack of cheap catalysts. Platinum works, it’s just too expensive and rare.
An immigration judge in Newark on Friday suspended the deportation of a Venezuelan man who is married to an American man, responding to an unusual signal this week from the Obama administration that it is exploring legal avenues for recognizing same-sex marriages in immigration cases.
Einstein was right: There is a four-dimensional space-time vortex around Earth, and the spin of Earth does twist space-time.
That’s according to NASA, in an announcement made 52 years after scientists first imagined how to test Einstein’s theory on space-time – before the technology to test it had even been invented.
Scientists at Stanford have developed a battery that uses nanotechnology to create electricity from the difference in salt content between fresh water and sea water. The researchers hope to use the technology to create power plants at estuaries where fresh water rivers join the ocean.
A U.S. Green Building Council partnership released its third annual report listing the greenest colleges nationwide. The online-only guide, available as a free download, includes brief summaries of sustainability initiatives at each of the top 311 schools, as well a dozen or so data points on things like renewable power use, energy efficiency and waste disposal.
More than 16,000 low-income kids who faced losing their subsidized child care next year will get some good news from Mayor Bloomberg Friday.
The mayor plans to announce that he’s found $40 million to continue providing child care to all kids now receiving the subsidy their working parents depend.
The Tunisian fruit and vegetable seller who inspired uprisings across the Arab world when he set himself on fire — is now the subject of a movie.
Mohamed Bouazizi was trying to make a living amid desperate economic conditions in Tunisia when police found he didn’t have a license to trade and tried to stop him. He turned his despair into protest by setting himself on fire.
Tunisian movie producer Tarak Ben Ammar, who at the time was shooting his latest film — starring Antonio Banderas — was approached by the Bouazizi’s family after they were inundated by worldwide media.

Scientists announced they have achieved one of the “Holy Grails of science” by creating the world’s first practical photosynthesis device, an artificial leaf of playing-card-size that can be used to mimic the process that green plants use to convert sunlight and water into energy.
The photosynthetic gadget, unveiled at a March 27 American Chemical Society meeting, uses sunlight to split water molecules into oxygen and hydrogen, and is reputedly 10 times more efficient than a natural leaf. Described as a milestones in the drive for sustainable energy, researchers say it will revolutionize power storage, especially in remote areas that don’t currently have electricity.

U.S. Rep. Jim Langevin is encouraging other agencies to follow the lead of the Rhode Island Public Transit Authority that recently bought 53 hybrid buses and upgraded 10 trolleys to run on a hybrid system.
Langevin touted the agency’s investment during a speech on the floor of the U.S. House of Representatives Wednesday saying that the new fleet will save about 20 percent on fuel usage.
If you want to understand what shaped our president, don’t look to his father’s disappearance. It was his unconventional mother who made him.
In 1960, before the Civil Rights Act, before the women’s movement, a smart, white 17-year-old arrived at college. Within weeks she became pregnant and dropped out of school to marry an African — at a time when doing so qualified as a felony in nearly half of America.
The startling part of her story was her conviction—as the child grew into a man—that her son was so gifted “that he can do anything he ever wants in the world, even be president of the United States.”
In a new effort to reduce duplication and ensure the U.S. government operates more efficiently, 137 federal data centers have been identified by the Obama Administration as unnecessary overlap and scheduled for shut down this year.
The planned consolidation of these and hundreds of other data centers over the next four and a half years is expected to save more than $3 billion for American taxpayers.

A 15-month-old dog had to overcome fire and smoke — and her breed’s reputation — to become a national hero.
The dog named Diamond is a pit bull—the canine most often cited as vicious in news reports and the most abandoned and euthanized dog in the country. But today, the Society for the Prevention of Cruelty to Animals Los Angeles presented Diamond with their 29th annual National Hero Dog award.
