Optical Atomic Clock: A long look at the captured atoms
Optical clocks might become the atomic clocks of the future. Their "pendulum", i.e. the regular oscillation process which each clock needs, is an oscillation in the range of the visible light. view more (2008-02-06)
National Physical Laboratory Stages Unique On-Line Experiments
Does your computer’s clock always run slow? How good are human beings at estimating? How much does gravity vary over the globe? With your help we are attempting to find answers to these questions as part of a huge on-line Web event to celebrate World Metrology Day 2001, Sunday 20th May. This is the first time NPL have attempted such a... view more... (2001-05-18)
Optical atomic clock becomes portable
You imagine a clock to be different - yet the optical table with its many complicated set-ups really is one. Optical clocks like the strontium clock in the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig could be the atomic clocks of the future; some of them though are already ten times more precise and stable than the best primary... view more...

Mercury atomic clock keeps time with record accuracy
An experimental atomic clock based on a single mercury atom is now at least five times more precise than the national standard clock based on a "fountain" of cesium atoms. view more (2006-07-17)
Research leads to healthful strategies for re-setting the body's clock
Everyone is equipped with a biological clock, a region in the brain the size of a corn kernel, which dictates our sleep-wake cycles, and plays a major role in our physical and mental health. view more (2006-03-23)
Experimental atomic clock uses ytterbium 'pancakes'
Scientists at the National Institute of Standards and Technology (NIST) working with Russian colleagues have significantly improved the design of optical atomic clocks that hold thousands of atoms in a lattice made of intersecting laser beams. view more (2006-03-07)
Atomic clock signals may be best shared by fiber-optics
Time and frequency information can be transferred between laboratories or to other users in several ways, often using the Global Positioning System (GPS). But today's best atomic clocks are so accurate—neither gaining nor losing one second in as long as 400 million years—that more stable methods are needed. view more (2007-03-05)
Ytterbium gains ground in quest for next-generation atomic clocks
An experimental atomic clock based on ytterbium atoms is about four times more accurate than it was several years ago, giving it a precision comparable to that of the NIST-F1 cesium fountain clock, the nation's civilian time standard, scientists at the National Institute of Standards and Technology (NIST) report in Physical Review Letters. view more (2009-08-12)
NIST atomic fountain clock gets much better with time
The world's best clock, NIST-F1, has been improved over the past few years and now measures time and frequency more than twice as accurately as it did in 1999 when first used as a national standard, physicists at the National Institute of Standards and Technology (NIST) report. view more (2005-09-26)
Physicists make atomic clock breakthrough
Andrei Derevianko, Kyle Beloy, and Ulyana Safronova sat down six months ago and began work on a calculation that will help the world keep better time. In competition with scientists at the University of New South Wales, the University team led by associate professor Derevianko conducted research that increased the accuracy of atomic clocks, and... view more...

Active optical clock
Institute of Quantum Electronics, School of Electronics Engineering and Computer Science, Peking University, has proposed the concept, principles and techniques of active optical clock. view more (2009-04-13)
FLYING THROUGH TIME
UK scientists demonstrate Einstein's theories of relativity and 'travel' through time view more (1999-12-22)
Circadian surprise: A heat sensor for body-clock synchronization
New research on the fruit-fly brain points to a possible mechanism by which temperature influences the body clock, according to scientists from Queen Mary, University of London. view more (2009-10-30)
Atomic fountain clocks are becoming still more stable
They are at present the most accurate clocks in the world: Caesium fountain clocks furnish the second accurate to 15 places after the decimal point. Until they reach this accuracy, caesium fountain clocks, however, need a certain measurement time. view more (2009-03-18)
Tandem ions may lead the way to better atomic clocks
Physicists at the Commerce Department's National Institute of Standards and Technology (NIST) have used the natural oscillations of two different types of charged atoms, or ions, confined together in a single trap, to produce the "ticks" that may power a future atomic clock. view more (2005-07-29)
Researchers propose new molecule to explain circadian clock
The internal clock in living beings that regulates sleeping and waking patterns -- usually called the circadian clock -- has often befuddled scientists due to its mysterious time delays. Molecular interactions that regulate the circadian clock happen within milliseconds, yet the body clock resets about every 24 hours. view more (2007-08-28)
More evidence mammals, fruit flies share make-up on function of biological clocks
A study by researchers at New York University and the University of London offers additional evidence that mammals and fruit flies share a common genetic makeup that determines the function of their internal biological clocks. The study appears in the latest issue of Current Biology. view more (2006-03-07)
Doomsday clock moves forward 2 minutes
The Bulletin of the Atomic Scientists (BAS) is moving the minute hand of the Doomsday Clock today from seven to five minutes to midnight. view more (2007-01-18)
Biologists find biological clock for smell in mice
Biologists at Washington University in St. Louis have discovered a large biological clock in the smelling center of mice brains and have revealed that the sense of smell for mice is stronger at night, peaking in evening hours and waning during day light hours. view more (2006-12-19)
Physicists lead the field in solving matter mystery of the Big Bang
A University of Sussex-led team of scientists is ahead in the race to solve one of the biggest mysteries of our physical world: why the Universe contains matter. With the help of a new £2.3 million grant, the team is working on a project to make one of the most sensitive measurements ever of sub-atomic particles. The results, expected within... view more...
