Physicists might have to rethink what they know about, well, everything. European researchers dropped a potential bombshell on their colleagues around the world Wednesday by reporting that sophisticated new measurements indicate the radius of the proton is 4% smaller than previously believed. In a world where measurements out to a dozen or more decimal places are routine, a 4% difference in this subatomic particle — found in every atom's nucleus — is phenomenally large, and the finding has left theoreticians scratching their heads in wonderment and confusion.

Hoping a public outing will force Chinese drywall manufacturers to take responsibility for their products, the Consumer Product Safety Commission has published a list of brands that emit the most sulfuric gas compounds. For more than a year, the agency has been investigating problems with drywall imported from China. Hydrogen sulfide released from some brands of Chinese-made wallboard is the cause of corrosion in appliances, air conditioning coils and other metals, triggering about 3,300 complaints to the federal government.

The Port of Los Angeles, the nation's busiest container port, is negotiating with an alternative-fuel vehicle manufacturer to purchase and evaluate the company's heavy-duty, zero-emission trucks, which use a hydrogen fuel cell hybrid electric power system. The company is Vision Industries Corp. of Florida, doing business as Vision Motor Corp. in California. Vision's research and development facility is in El Segundo and its manufacturing plant is in Whittier, said its president and chief executive, Martin Schuermann.

Vitaly Ginzburg, the Russian physicist who played a key role in the Soviet Union's development of the hydrogen bomb and who later won a Nobel Prize for his work on the theoretical underpinnings of superconductivity, died in Moscow late Sunday of cardiac arrest. He was 93 and had been in ill health for some time. A pioneering theoretical physicist who often deprecated his own abilities in mathematics, Ginzburg made seminal contributions in a number of areas of physics, including quantum theory, astrophysics and radioastronomy.

The hydrogen car may have legions of fervent fans, but Energy Secretary Steven Chu apparently is not among them. Earlier this year, the Nobel Prize-winning scientist essentially zeroed government funding for the vehicles and came close to mocking their potential, saying the technology needs four "miracles" before it can become widely adopted. "Saints only need three," he said in a magazine interview. But the hydrogen car is back. On Thursday, the Senate agreed to restore nearly all the money for research that the Obama administration had proposed to cut. This year's revival of government funding is unlikely to end the dispute over the vehicles, however.

NASA's lunar-mapping satellite has just begun its four-year mission searching for water on the moon, but it has already turned up a discovery that has scientists scratching their heads. The Lunar Reconnaissance Orbiter's seven scientific instruments have indeed confirmed the presence of large amounts of hydrogen -- a marker for water -- in permanently shadowed south pole craters, where scientists had known there were deposits of hydrogen. But the instruments have also found the element in regions where the sun shines.

I've driven lots of cars. I've wallowed like a Russian oligarch pig in the gorgeous mud of a $1.6-million Bugatti Veyron. I've spit tailpipe fire across the midnight Mojave at the wheel of a Lamborghini. I've brushed gape-mouthed peasants aside with the chrome cowcatcher grille of a Rolls Royce Phantom. Yet I have never driven a car half as advanced, as futuristic, as blind-with-science as the Honda FCX Clarity hydrogen fuel-cell vehicle. Nor one so expensive. More on that in a moment.

MIT researchers have developed an inexpensive technique to split water into hydrogen and oxygen, a feat that would allow energy produced by sun-powered photovoltaic cells to be stored for future use. Daniel Nocera and Matthew Kanan reported Friday in the journal Science that they had created an unusual catalyst for the reaction by dissolving cobalt and phosphate in water containing conductive glass electrodes. When a current was applied, the catalyst plated onto the surface of the electrodes, and hydrogen began forming at one and oxygen at the other.

The Shell station looks typical, with recognizable yellow and red signs plastered on the islands and gasoline pumps. But one pump sticks out. It sports a bright blue "Hydrogen" label above a video screen. On its side is a metal lockbox and a new kind of dispenser -- new at least to the everyday gas station visitor.
