Individual differences in a clock gene predict decline of performance during sleep deprivation
People are known to differ markedly in their response to sleep deprivation, but the biological underpinnings of these differences have remained difficult to identify. view more (2007-03-09)
Physicists Entangle Photon and Atom in Atomic Cloud
uantum communication networks show great promise in becoming a highly secure communications system. By carrying information with photons or atoms, which are entangled so that the behavior of one affects the other, the network can easily detect any eavesdropper who tries to tap the system. view more (2005-07-27)
New Chip Design Delivers Better Performance, Longer Battery Life for Cell Phones, WiFi, and Other Wireless Communications
Anyone who uses a cell phone or a WiFi laptop knows the irritation of a dead-battery surprise. view more (2006-04-20)
New record for information storage and retrieval lifetime advances quantum networks
Physicists have taken a significant step toward creation of quantum networks by establishing a new record for the length of time that quantum information can be stored in and retrieved from an ensemble of very cold atoms. view more (2008-12-08)
Researchers outline structure of largest nonvirus particle ever crystallized
Researchers at UCLA's California NanoSystems Institute, the David Geffen School of Medicine at UCLA and the Howard Hughes Medical Institute have modeled the structure of the largest cellular particle ever crystallized, suggesting ways to engineer the particles for drug delivery. view more (2007-11-27)
Discovery by UC Riverside physicists could enable development of faster computers
Physicists at UC Riverside have made an accidental discovery in the lab that has potential to change how information in computers can be transported or stored. Dependent on the "spin" of electrons, a property electrons possess that makes them behave like tiny magnets, the discovery could help in the development of spin-based... view more... (2008-06-24)
The food-energy cellular connection revealed
Our body's activity levels fall and rise to the beat of our internal drums-the 24-hour cycles that govern fundamental physiological functions, from sleeping and feeding patterns to the energy available to our cells. view more (2009-10-16)
WUSTL research finds individual cells isolated from the biological clock can keep daily time, but are unreliable
Alexis Webb enters a small room at Washington University in St. Louis with walls, floor and ceiling painted dark green, shuts the door, turns off the lights and bends over a microscope in a black box draped with black cloth. Through the microscope, she can see a single nerve cell on a glass cover slip glowing dimly. view more (2009-09-10)
One-atom-thick materials promise a 'new industrial revolution'
Scientists at The University of Manchester have discovered a new class of materials which have previously only existed in science fiction films and books. view more (2005-07-21)
Light-induced hormone surge points to benefits of light therapy
A report in the November Cell Metabolism reveals powerful effects of light on the adrenal glands, a finding that might explain the broad benefits of bright light therapy for a variety of conditions, including sleep and depressive disorders, according to researchers. view more (2005-11-09)
'NMR on a chip' features NIST magnetic mini-sensor
A super-sensitive mini-sensor developed at the National Institute of Standards and Technology (NIST) can detect nuclear magnetic resonance (NMR) in tiny samples of fluids flowing through a novel microchip. view more (2008-02-20)
Scientists retrace evolution with first atomic structure of an ancient protein
Scientists have determined for the first time the atomic structure of an ancient protein, revealing in unprecedented detail how genes evolved their functions. view more (2007-08-17)
A Biological Basis for the 8-Hour Workday?
The circadian clock coordinates physiological and behavioral processes on a 24-hour rhythm, allowing animals to anticipate changes in their environment and prepare accordingly. Scientists already know that some genes are controlled by the clock and are turned on only one time during each 24-hour cycle. view more (2009-04-24)
Chemotherapy for breast cancer is associated with disruption of sleep-wake rhythm in women
A study in the Sept.1 issue of the journal Sleep shows that the sleep-wake activity rhythms of breast cancer patients are impaired during the administration of chemotherapy. view more (2009-09-01)
True properties of carbon nanotubes measured
For more than 15 years, carbon nanotubes (CNTs) have been the flagship material of nanotechnology. Researchers have conceived applications for nanotubes ranging from microelectronic devices to cancer therapy. Their atomic structure should, in theory, give them mechanical and electrical properties far superior to most common materials. view more (2008-08-18)
Saturn's rings have own atmosphere
Data from the NASA/ESA/ASI Cassini spacecraft indicate that Saturn's majestic ring system has its own atmosphere-separate from that of the planet itself. view more (2005-08-18)
U of T team heats up gold to surprising effect: it gets harder not softer
Common sense tells us that when you heat something up it gets softer, but a team of researchers, led by University of Toronto chemistry and physics professor R.J. Dwayne Miller, has demonstrated the exact opposite. view more (2009-01-23)
UCLA researchers outline the structure of the largest non-virus particle ever crystallized

New molecular clock from LLNL and CDC indicates smallpox evolved earlier than believed
Smallpox is older than thought, according to results of a new technique reported in the Sept. 24 issue of the Proceedings of the National Academy of Sciences by researchers from Lawrence Livermore National Laboratory and the Centers for Disease Control (CDC). view more (2007-09-26)
K-State physics lab becoming a frontrunner in ultrafast laser research
For decades, the J.R. Macdonald Laboratory at Kansas State University has been known worldwide as a center for atomic collision physics using particle accelerators. Now, researchers at the lab are working toward making it known for ultrafast laser science. view more (2008-10-29)
