In the latest advance in efforts to find an inexpensive way to make hydrogen from ordinary water one of the keys to the much-discussed "hydrogen economy" scientists are reporting that powder from high-grade charcoal and other forms of carbon can free hydrogen from water illuminated with laser pulses. A report on the discovery appears in ACS' Journal of Physical Chemistry C.

Ikuko Akimoto and colleagues point out that traditional approaches to breaking down water, which consists of hydrogen and oxygen, involve use of expensive catalysts or electric current passed through water. Since economical production of hydrogen from water could foster a transition from coal, oil and other fossil fuels, scientists have been searching for less expensive catalysts. Those materials speed up chemical reactions that otherwise would not work effectively. Based on hints from research decades ago, the scientists decided to check out the ability of carbon powder and charcoal powder, which are inexpensive and readily available, to help split hydrogen gas from oxygen in water.

Akimoto's team tested carbon and charcoal powders by adding them to water and beaming a laser in nanosecond pulses at the mixtures. The experiment generated hydrogen at room temperature without the need for costly catalysts or electrodes. Its success provides an alternative, inexpensive method for producing small amounts of hydrogen from water.

Smoke from expanding Yosemite wildfire triggers air-quality warnings 100 miles away

One of the largest wildfires in California's history has triggered a smoke plume that has worsened air quality more than 100 miles away in Nevada.

The smoky haze from the Rim Fire -- which?has raged for 12 days in the area of Yosemite National Park --?sparked emergency warnings in the Reno and Carson City area, The Associated Press reported. Schoolchildren were kept inside for the second time in a week, people went to hospitals complaining of eye and throat irritation and officials urged people to avoid all physical activity outdoors.

"It's five hours away," said 22-year-old bartender Renee Dishman in disbelief after learning the source of the haze. "I can't run. I can't breathe. It makes me sneeze."

The blaze called the "Rim Fire," now 20 percent contained thanks to the efforts of more than 4,000 firefighters, is quickly becoming one of the largest wildfires in California history. NBC's Miguel Almaguer reports.

Dennis Fry, a Reno auto body specialist for nearly 30 years, remembered smoke this thick when he worked on a logging crew and helped fight fires in Oregon during the 1970s.

"But never in Reno, not this bad," he said. "You could actually see the smoke inside my body shop."

The fire has already scorched nearly 290 square miles - an area almost as large as New York City - and by Tuesday night had destroyed 31 homes and 80 other structures. In all the fire threatens 4,500 homes, 1,000 outbuildings and six commercial buildings.

Though firefighters have gained some ground on the blaze, there is little doubt it is expanding - from 144,000 acres on Sunday to about 184,000 acres by Tuesday evening. Some 42,000 acres of Yosemite is charred, nearly double the area late Monday.

The Rim Fire was among the fastest-moving of dozens of large wildfires raging across the parched West. The fires have strained resources and even prompted fire managers to open talks with Pentagon commanders and Canadian officials about possible reinforcements.

"We are making progress," Daniel Berlant, a spokesman for the California Department of Forestry and Fire Protection, told Reuters on Tuesday, adding that fire managers were looking forward to a cooling trend forecast for the end of the week. "That would bring some much-needed relief," he said.

The Rim Fire is the seventh-largest wildfire since California started keeping records. What sparked the blaze is still under investigation.

Much of the terrain is steep and rocky, and if firefighters were dropped into the burn zone, there would be no escape route.

So firefighters are deploying a massive DC-10 jet to attack the fire from the air. Crew members can drop nearly 12,000 gallons of fire retardant from the plane?s payload on each run. Each drop helps slow the flames as the retardant paints the hillsides red. At least 15 helicopters and other fixed wing aircraft were also in use to battle the blaze from above.

On a helicopter flight 10,000 feet above the Rim Fire, NBC News reported flames leaping hundreds of feet into the air and fiery hot spots on the forested slopes of the Sierra Nevada as the blaze consumed broad areas.

Fire officials have advised the evacuation of the area around Tuolumne City and in areas around the western boundary of Yosemite.

The Rim Fire has scorched hundreds of square miles near Yosemite National Park.

A mandatory evacuation was in effect for homes north of Old Yosemite Road as well as other nearby areas.

Elite Hotshot crews ??among 3,700 firefighters battling the blaze ??were stationed near residential areas, their first priority to protect life and property, and area residents were confident in their ability to do that.

"I have incredible faith in the firefighters," Sarah Whitney?of Tuolumne City?told NBC Bay Area on Tuesday. "They're walking around in their tactical uniforms and dumping retardant.... All that work, it's amazing."

Posters in towns and cities close to the fire thanked the crews for their work.

On Tuesday, earlier fears that the fire would disrupt water and power supplies to the city of San Francisco, about 200 miles away, were somewhat diminished as the blaze moved away from the Hetch Hetchy Reservoir.

"It looks great out there. No concerns," Glen Stratton, an operations section chief on the Rim Fire, told NBC Bay Area about the reservoir threat.

NBC News' Alastair Jamieson, The Associated Press and Reuters contributed to this report.

Egyptian soldiers will no longer swear loyalty to president

CAIRO (Reuters) - Egyptian soldiers will no longer swear loyalty directly to the president of the republic, according to a published decree, a symbolic change analysts said underlined the military's independence from any civilian control.

Officers will vow to "execute the orders of my leadership", according to the amended oath of allegiance, that removes the phrase: "I will be loyal to the president of the republic".

The decree was issued on Tuesday by interim head of state Adly Mansour, head of the army-backed administration installed by the military after it deposed President Mohamed Mursi of the Muslim Brotherhood on July 3.

"The change is a positive one. It was meant in order not to make the oath personal. It already includes reference to the president, as he is one of the army's leaders," army spokesman Ahmed Ali told Reuters. "This way makes the loyalty to the leadership and not to a person," he said.

Analysts saw another symbolic aspect to the shift.

Nathan Brown, a professor at George Washington University and a leading Egypt expert, noted that the text of the decision showed that it was based on material presented to the president by army chief General Abdel Fattah al-Sisi.

Sisi also serves as a vice president and as the defense minister in the interim government formed after the army overthrew Mursi last month.

"I don't think anyone would believe that this is likely to be the president's initiative," he said.

"In short, this is a military-initiated step, rubber-stamped by an acting president," he said. "It is clear from this who is calling the shots."

Brown also noted that in contrast to other countries, where the army "might swear allegiance to the constitution and laws", in Egypt, soldiers and officers will no longer be swearing allegiance to "any civilian official, law or procedure".

Why do carriers suck so much? - Talk Mobile

Cellular carriers are strange entities. They offer devices that in the grand scheme aren't that expensive for what they are, but yet have customers conditioned to expect them to be much cheaper and not think about the long-term cost. They built empires around multi-year contracts, but in an age where mobile technology was advancing at a rate that was positively lethargic compared to today.

They fell into a routine, picking up the old habits, policies, and mindsets of the landline era. The largest carriers are merely permutations of the old wireline telecoms - AT&T and Verizon can both trace their lineage back to the old AT&T monopoly, Sprint began life as the Brown Telephone Company in 1899, T-Mobile comes from the post-World War II German post office, and so on.

So is it history that explains why cellular carriers are lumped in with banks, airlines, and the cable provider as the most hated of companies? Or is it something else in how they do business?

Do they really suck that much, or is it all in our heads?
