Democratic Congress Begins to Put Its Stamp on Science

Science: Six months into their rule on Capitol Hill, the Democrats have begun to make their mark on science policy. Many of their moves have underscored differences with the White House, including efforts to overturn the ban on federal funding for work on new embryonic stem lines, prominent accusations that the Bush Administration has politicized science advice, and proposals to increase and reshape funding for climate change research (see sidebar). But as far as the Administration's most prominent science initiative is concerned, the new Congress has so far been more than supportive, at least in loosening the purse strings: It is poised to top the president's generous requests for the multiagency American Competitiveness Initiative (ACI), which is aimed at sharply increasing funds for the physical sciences.

Will Mars Rover Survive the Crater of Doom?

5.5 Million Euro Project for Molecular Machine Research

AZoNano.com: Operating on a molecular level is no longer just a dream for the future.

The project team will design and synthesize molecules and nanometer sized aggregates of molecules that will operate as pumps, rotors, actuators and "intelligent" materials. The German Research Foundation has approved a grant of more than EUR 5.5 million to the SFB 677 "Function by Switching” for its first four years. Spokesman of the project is Professor Rainer Herges (Chair of Organic Chemistry).

Calendar question over star disc

BBC: Archaeologists have revived the debate over whether a spectacular Bronze Age disc from Germany is one of the earliest known calendars. The Nebra disc is emblazoned with symbols of the Sun, Moon and stars and said by some to be 3,600 years old. Writing in the journal Antiquity, a team casts doubt on the idea the disc was used by ancient astronomers as a precision tool for observing the sky. They instead argue that the disc was used for shamanistic rituals.

Stars Have Earth-like weather

space.com: The skies of stars might experience weather like that on planets, says astrophysicist Oleg Kochukhov and colleagues at Uppsala University in Sweden. The drifting clouds are wispy, "just like cirrus clouds on Earth"-except these are made of mercury, he adds. The research in publish online in Nature Physics.

A Struggle for the Soul of Physics

Various: As though their knowledge of the quantum secrets came with the power of prophecy, some three dozen of Europe’s best physicists ended their 1932 meeting in Copenhagen with a parody of Goethe’s “Faust.” Physicist Gino Segrè's new book, Faust in Copenhagen forms the basis of a New York Times review by George Johnson. Joscelyn Jurich in her review for the San Francisco Chronicle, looks in more detail at the links between Fraust and physics in the 1930s.

Congress scrutinizes NASA's Earth science program

Congressional Quarterly: A squeeze on funding for satellites to look down on the Earth’s environment at a time of growing need for research into the effects of climate change is creating alarm among scientists and on Capitol Hill. NASA's Earth science budget has been cut by 30 percent to help pay for the President's Moon-Mars vision and for repairs to the space shuttle. A significant number of Earth observation satellites are failing or at the limit of their design lifetime, and few are expected to be replaced. Now the Senate's commerce committee which monitors NASA, is applying more pressure to Mike Griffen, NASA administrator to maintain US expertise in monitoring the planet says CQ's William Scally.

Particle Collider in Europe, Long Awaited by Physicists, Is Delayed Until 2008

The Chronicle of Higher Education: CERN, the European Organization for Nuclear Research, has announced that it will delay starting up the giant Large Hadron Collider from this November until May 2008. The decision was taken at a council meeting earlier this week.

The move has a number of implications for the particle physics community, including the likihood that the lifetime of Fermilab's collider the Tevatron might extended in order to try and beat the LHC to discovery of the Higgs Boson particle.

Is There Glue in Cuprate Superconductors?

Science: More than 20 years after the discovery of cuprate superconductors, physicists do not agree on what mechanism causes the loss of electrical resistance at temperatures as high as 160 K (known as Tc, the transition temperature). They do agree that electron pairs are crucial because they can form a condensate that flows without resistance, but the interaction that causes the pairs to form is disputed. Philip W. Andersen suggests in this week's Science that the bosonic glue most physicists believe is needed to explain the superconducting behavior is folklore rather than the result of scientific logic.

Pakistan building new reactor

BBC: Satellite images show that Pakistan is building a nuclear reactor that could be used to produce weapons-grade plutonium, says the Institute of Science for International Security (Isis).

Senate Adopts Energy Bill Raising Mileage for Cars

New York Times: The Senate passed a broad energy bill late Thursday that would, among other things, require the first big increase in fuel mileage requirements for passenger cars in more than two decades.

Middleman Fixes Center of the Earth

ScienceNow: A geoscientist has pinpointed the motion of the center of the Earth to within 1 millimeter--or about the thickness of a dime--per year, cutting the uncertainty about Earth's center by more than half. The new measurement and the method that made it possible should help scientists more accurately track increases in sea level caused by global climate change.

Legislators Back Boost for Science

ScienceNow: A House spending panel has exceeded President George W. Bush's 2008 budget request for four key science agencies. That's very good news, say science lobbyists, who nevertheless warned that the bill must still survive a threatened White House veto if its higher spending levels aren't first whittled down in the Senate. Science and math education is treated especially well, in line with the bipartisan push to improve teacher quality and raise student test scores.
