The Supreme Court melts down over greenhouse gasses

Slate.com: If there is anything stranger than writing up your story on global warming in a T-shirt … in late November … in the District of Columbia, I can't quite think what it is. In fact nothing about this morning's oral argument, in Massachusetts v. Environmental Protection Agency, is normal. The justices are perhaps deciding, after all, the most urgent scientific question facing the planet: They are deciding Bush v. Gore's Movie.

Scientists decode ancient astral computer

Sydney Morning Herald: A mysterious device salvaged from an ancient Roman shipwreck has astounded scientists who have finally unlocked its secrets.

CERN takes next step towards completing the LHC

Wired: The elevator buttons in front of me, hand-labeled in black marker, speak volumes: "Sky," says one, the other, "Hell."

Sky is the Swiss-French border, pastoral Geneva countryside in the shadow of soaring Alpine mountains. Hell is "The Machine" -- a 16.8-mile underground ring where, in almost precisely a year, superconducting magnets will begin accelerating atomic particles to within a hairsbreadth of the speed of light, and smash them into each other.

Silicon Nanowires to Reduce Size of Microchips

AZoNano.com: Silicon nanowires can help to further reduce the size of microchips. Scientists at the Max Planck Institute for Microstructure Physics in Halle have for the first time developed single crystal silicon nanowires that fulfil the key criteria to this end. The researchers used aluminium as a catalyst to grow the nanowires. To date, scientists have usually deployed gold for this purpose. However, even traces of the precious metal have a drastically detrimental effect on the function of semiconductor components. This is not the case with other metals, which catalyse the process, but only at temperatures that would not enable economically viable processes. On the other hand, aluminium is an effective catalyst even at relatively low temperatures and does not impair the quality of electronic components

Dr. Nail VS The Monster

Popular Science: In 1995 a Clemson University graduate student named Ed Sutt took off for a spur-of-the-moment trip to the Caribbean. But beaches and rum drinks weren’t on the agenda for this civil engineer. Hurricane Marilyn had just torn through St. Thomas, and Sutt was part of a team examining how and why 80 percent of the island’s homes and businesses had collapsed in the storm’s 95mph winds.

A Free-for-All on Science and Religion

The New York Times: Maybe the pivotal moment came when Steven Weinberg, a Nobel laureate in physics, warned that “the world needs to wake up from its long nightmare of religious belief,” or when a Nobelist in chemistry, Sir Harold Kroto, called for the John Templeton Foundation to give its next $1.5 million prize for “progress in spiritual discoveries” to an atheist — Richard Dawkins, the Oxford evolutionary biologist whose book “The God Delusion” is a national best-seller.

Another step toward quantum computers

ZDNET: One day, we might use super fast computers based on quantum physics. But how these computers will read data? An international team from Germany and the U.S. has just shown that it's possible to read data stored as nuclear 'spins.' This new way of reading the spin of thousands of electrons is not the ultimate goal: a real quantum computer would need to read the spins of single particles. Still, this new method is far better than previous ones which only allowed to read the net spins of the electrons of billion of atoms combined.

Reading votes to close physics department

Guardian Unlimited: The University of Reading last night confirmed its controversial decision to close the physics department.

Kremlin grabs control of physicists company

The Washington Post: Physicist Vladislav Tetyukhin and entrepreneur Vyacheslav Bresht, who rescued titanium manufactuer VSMPO-Avisma in the 1990s and converted it into a billion dollar company, have lost their battle to remain independent from the Russian government. Tetyukhin invented the process VSMPO-Avisma uses to smelt titanium in 1957. The Russian government planned its takeover of VSMPO-Avisma through Rosoboroexport, a state-owned arms export agency. VSMPO-Avisma is considered to be of strategic importance to Russia, as it is the world's largest supplier of titanium, which is used in both civilian and military aircraft. Since Rosoboroexport announced its interest in taking over VSMPO-Avisma, the company has been under a tax audit, and the prosecutor-general began an investigation into the share structure of the VSMPO-Avisma as a way of applying pressure to shareholders to sell their stake to Rosoboroexport at a cheap price. Tetyukhin was quoted in the financial times newspaper some months ago as saying "Why do their patriotic feelings show only now, when the company is making a profit, when it has been cleaned up and restructured?"

According to the Washington Post, Rosoboroexport completed its takeover of VSMPO-Avisma last week when it acquired 66 percent of the shares in the company. At the same time, the tax audit and prosecutor-general investigation against the previous shareholders have been dropped. Tetyukhin, will retain a 3.8 percent stake in the company and Rosoboronexport has assured VSMPO-Avisma's international customers such as Boeing, which account for 75 percent of the company's $1 billion in annual sales, that they will continue to be a reliable supplier.

More Letters in the Particle Alphabet

ScienceNow: Getting at the root of all existence isn't easy. For 75 years, physicists have been smashing atoms together in increasingly powerful particle accelerators, while theorists have been calculating what those collisions should be producing. The work has allowed scientists to unearth matter's most basic components. Now, physicists have added two more particles to the list and, with that, have taken science a step closer to unraveling the mystery of just what the universe is made of.

The Ultimate "Flash Photography"

ScienceNow: Smile and prepare to be vaporized! In what you might call the most violent snap-shot ever, physicists have used a blast of x-rays to determine the structure of a tiny object, even as the x-rays blew it apart. The "single-shot" technique marks an important step toward deciphering the structure of proteins by zapping just a single molecule--a potentially revolutionary technique that physicists hope to perfect with the world's first x-ray lasers, currently under construction in the U.S., Germany, and Japan.

Physicists prove complaints about new basketball are valid

Physics Today Online: This year the National Basketball Association switched from leather to synthetic basketballs to cut down on the amount of variation in behavior between balls used on the court. Unlike leather balls, the new synthetic balls--made out of a durable micro-fiber composite--do not require conditioning before use on the court, nor do they pick up moisture (a leather ball can gain 10% of its weight from moisture by the end of a game). A synthetic basketball has a designed surface that is supposed to be easier to grip than its leather counterpart. However, the NBA players have all complained about the new basketballs saying that don't react or feel as easy to use as the old leather balls. Now, Kaushik De and colleagues from the University of Texas, Austin Physics Department have proven that the players are correct. Tests carried out under laboratory conditions, show that the synthetic ball bounces 5 to 8 percent lower than a typical leather ball when dropped from 4 ft, and the new ball bounces 30 percent more erratically. Moreover, because the new balls do not absorb moisture, the surface of the basketball retains a thin layer of water, making them harder to grip by the end of the game. The physicists suggest some improvements to the design of the synthetic ball (making it able to absorb more water for example) while they continue carrying out their next set of tests, including aerodynamic drag experiments in a wind tunnel.

Galactic Building Block Busters

ScienceNow: If a castle is built with nearby rocks, you'd expect the stone walls to be made of the same stuff as any remaining boulders in the area. Likewise, if our Milky Way galaxy grew through the merging of smaller dwarf galaxies, you'd expect it to contain the same types of stars as the remaining dwarfs that have not been incorporated. But detailed observations of four of these dwarf galaxies show that this is not the case, indicating that theories about how galaxies form are incomplete.
