Small, low-noise oscillator may help in surveillance
A new design for a microwave oscillator that is smaller, simpler, and produces clearer signals at a single frequency than comparable devices has been invented at the National Institute of Standards and Technology (NIST). view more (2006-09-18)
Reach out and touch an oscillator: Cornell researchers find a new way to read nanoscale vibrations
Nanomechanical oscillators — tiny strips of vibrating silicon only a few hundred atoms thick — are the subject of extensive study by nanotechnology researchers. They could someday replace bulky quartz crystals in electronic circuits or be used to detect and identify bacteria and viruses. view more (2007-03-27)
Nano-signals get a boost from magnetic spin waves
Researchers have figured out how nanoscale microwave transmitters gain greater signal power than the sum of their parts-a finding that will help in the design of nano-oscillator arrays for possible use as transmitters and receivers in cell phones, radar systems, or computer chips. view more (2006-09-01)
Analog and digital - hand in hand
Digital and high-frequency analog integrated circuits are manufactured using their own specific processes, leading `separate lives` in the past. Using standard CMOS, both types of component can now be integrated on a single chip - like a wireless transmitter device. view more (2002-02-01)
A novel X-ray source could be brightest in the world
The future of high-intensity x-ray science has never been brighter now that scientists at U.S. Department of Energy's Argonne National Laboratory have devised a new type of next generation light sources. view more (2008-06-23)
Keeping the body in sync — The stability of cellular clocks
A study in Switzerland uses the tools of physics to show how our circadian clocks manage to keep accurate time in the noisy cellular environment. view more (2007-03-13)
UCLA engineers set new world record in generation of high-frequency submillimeter waves
Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have achieved a new world record in high-frequency submillimeter waves. view more (2007-04-17)
Simplest circadian clocks operate via orderly phosphate transfers
Researchers at Harvard University and the Howard Hughes Medical Institute have found that a simple circadian clock found in some bacteria operates by the rhythmic addition and subtraction of phosphate groups at two key locations on a single protein. view more (2007-10-05)
Study identifies food-related clock in the brain
In investigating the intricacies of the body's biological rhythms, scientists at Beth Israel Deaconess Medical Center (BIDMC) have discovered the existence of a "food-related clock" which can supersede the "light-based" master clock that serves as the body's primary timekeeper. view more (2008-05-23)
Major physics breakthrough in understanding supersolidity
Physicists at the University of Alberta, in Edmonton, Alberta, Canada, have made a major advance in the understanding of what appears to be a new state of matter. view more (2007-12-06)
On the Energy Trail: Berkeley Researchers Find New Details Following the Path of Solar Energy During Photosynthesis
Imagine a technology that would not only provide a green and renewable source of electrical energy, but could also help scrub the atmosphere of excessive carbon dioxide resulting from the burning of fossil fuels. view more (2008-04-28)
MAXUS 4 is now ready for launch
Following the success of the earlier Maxus flights which have taken place since 1992, the countdown is underway for the launch of ESA’s Maxus 4 sub-orbital microgravity mission on 29 April from ESRANGE, near Kiruna in northern Sweden. During the last two years, scientists from five European... view more (2001-04-26)
Multimode Magnetic Field and Position Sensor from Oxford University
Researchers at Oxford University's Physics Department have developed an extraordinarily versatile proximity sensor for the detection of objects, composed of ferrous and non-ferrous metals, ceramics, glasses and plastics. This new device could be used as a position or speed sensor in automotive... view more (2002-08-14)
High-frequency cryocooler is tiny, cold and efficient
A new cryogenic refrigerator has been demonstrated at the National Institute of Standards and Technology (NIST) that operates at twice the usual frequency, achieving a long-sought combination of small size, rapid cooling, low temperatures and high efficiency. view more (2007-02-16)
'Radio wave cooling' offers new twist on laser cooling
Visible and ultraviolet laser light has been used for years to cool trapped atoms-and more recently larger objects-by reducing the extent of their thermal motion. view more (2007-09-17)
Quantum Secrets of Photosynthesis Revealed
Through photosynthesis, green plants and cyanobacteria are able to transfer sunlight energy to molecular reaction centers for conversion into chemical energy with nearly 100-percent efficiency. view more (2007-04-13)
Measurement of stellar age from uranium decay
For the first time, an international team (led by Roger Cayrel, from Paris Observatory), could measure one uranium line in absorption in a star. This observation has several important implications. It is a great discovery, obtained thanks to the high resolution spectrograph UVES, assembled on one... view more (2001-02-05)
Genetic 'tag team' keeps cells on cycle
By surveying the activity of thousands of genes at several different time points, researchers at the Duke Institute for Genome Sciences & Policy have uncovered new evidence that a network of influential genes act as a kind of genetic tag team to orchestrate one of the most fundamental aspects... view more (2008-05-08)
Where is the proton? Yale scientists discover footprints of shared protons
This week in Science, Yale researchers present "roadmaps" showing that shared protons, a common loose link between two biological molecules, simply vibrate between the molecules as a local oscillator, rather than intimately entangling with the molecular vibrations of the attached... view more (2007-04-13)
OSU Creates World's First Transparent Integrated Circuit
Researchers at Oregon State University have created the world's first completely transparent integrated circuit from inorganic compounds, another major step forward for the rapidly evolving field of transparent electronics. view more (2006-03-20)
Magnetic field research could make computers 500 times more powerful
Magnetic fields created using nanotechnology could make computers up to 500 times more powerful, if new research is successful. view more (2006-06-23)
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)
Central and peripheral signals set the circadian liver clock
Anyone who has experienced jet lag will understand the importance of a smooth-running circadian clock. Crossing time zones decouples our biological rhythms from the natural cycle of light and dark we're used to. view more (2007-01-30)
Patent application for first ever coloured-light laser
Physicists at the University of Bonn have applied to patent a laser capable of producing almost every colour, from infrared through the entire visible spectrum to the UV range - and this is done not with high-cost optical crystals, but with the aid of a simple glass fibre. The new laser could bring... view more (2003-08-21)
