COUPP experiment tightens limits on dark matter

DOE/Fermi National Accelerator Laboratory
Peer-Reviewed Publication

Scientists working on the COUPP experiment at DOE's Fermilab today announced a new development in the quest to observe dark matter. The experiment tightened constraints on "spin-dependent" properties of WIMPS, particles that are candidates for dark matter. Their results, combined with the findings of other dark matter searches, contradict the claims for the observation of such particles by the DAMA experiment and further restrict the hunting ground for physicists to track their dark matter quarry.

New Argonne study may shed light on protein-drug interactions

DOE/Argonne National Laboratory
Peer-Reviewed Publication

Proteins, the biological molecules involved in virtually every action of every organism, may themselves move in surprising ways, according to a recent study from the US Department of Energy's Argonne National Laboratory that may shed new light on how proteins interact with drugs and other small molecules.

The midnight ride of the CMS tracking detector

DOE/Fermi National Accelerator Laboratory
Peer-Reviewed Publication

Scientists of the US CMS collaboration today joined their international colleagues in announcing the successful installation of the world's largest silicon tracking detector at CERN in Geneva, Switzerland. On Wednesday, Dec. 12, the six-ton CMS Silicon Strip Tracking Detector was carefully lowered 90 meters into the underground collision hall at the Large Hadron Collider particle accelerator. Installation began on Saturday, Dec. 15, and concluded early Sunday morning.

'Hybrid' semiconductors show zero thermal expansion; Could lead to hardier electronics

DOE/Argonne National Laboratory
Peer-Reviewed Publication

The fan in your computer is there to keep the microprocessor chip from heating to the point where its component materials start to expand, inducing cracks that interrupt the flow of electricity -- and not incidentally, ruin the chip. Thermal expansion can also separate semiconducting materials from the substrate, reduce performance through changes in the electronic structure of the material or warp the delicate structures that emit laser light.

Argonne bolsters efforts in security research

DOE/Argonne National Laboratory
Business Announcement

The US Department of Energy's Argonne National Laboratory has expanded its capabilities to protect US interests at home and abroad. The Vulnerability Assessment Team moved to Argonne's Nuclear Engineering Division last month from Los Alamos National Laboratory. The VAT conducts multidisciplinary research and development on physical security devices, systems and programs.

Argonne's nuclear energy research moves toward greater reliance on computer simulation

DOE/Argonne National Laboratory
Peer-Reviewed Publication

The US Department of Energy's Argonne National Laboratory is taking its nuclear energy research into new territory -- virtual territory that is. With the recent arrival of the new IBM Blue Gene/P and the lab's development of advanced computer models, Argonne has a critical role in making it possible to burn repeatedly nuclear fuel that now sits as waste, thus closing the nuclear fuel cycle and reducing the risk of nuclear proliferation.

New T-ray source could improve airport security, cancer detection

DOE/Argonne National Laboratory
Peer-Reviewed Publication

Going through airport security can be such a hassle. Shoes, laptops, toothpastes, watches and belts all get taken off, taken out, scanned, examined, handled and repacked. But "T-rays", a completely safe form of electromagnetic radiation, may reshape not only airport screening procedures but also medical imaging practices.
