How to rebuild an atomic clock
Atomic clocks are crucial for everyday living as they help our telecommunications, electrical power grids, GPS systems, transportation, and other processes around the world keep precise time. Some of these clocks use lasers and special resonator cavi.....»»
Passing Time: A Clock Made from Beer Bottles
Rick Stanley makes very special clocks. He makes clocks out of beer bottles (over 300 Yuengling beer bottles to be exact), clocks with bicycle bells, clocks featuring coins, dominoes, and fluids. He makes novelty clocks of great complexity alongside.....»»

Intel announces new, mildly improved CPUs for this year’s crop of laptops
Some CPUs get more cores, but we're mostly talking about clock-speed bumps. Enlarge / Intel's new laptop CPU lineup is a lot like the old CPU lineup. (credit: Intel) Intel's 13th-generation desktop CPU refresh is interes.....»»
New type of entanglement lets scientists "see" inside nuclei
Nuclear physicists have found a new way to use the Relativistic Heavy Ion Collider (RHIC)—a particle collider at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory—to see the shape and details inside atomic nuclei. The method re.....»»
Could getting rid of old cells turn back the clock on aging?
Researchers are investigating medicines that selectively kill decrepit cells. Enlarge (credit: Andrew Brookes/Getty Images) James Kirkland started his career in 1982 as a geriatrician, treating aging patients. But he fou.....»»
Research reveals fruit fly circadian clock mechanisms
The higher the temperatures, the faster physiological processes are. But there is an exception: the so-called circadian clock, which regulates the sleep-wake cycle in organisms. A fascinating question for scientists is why the inner clock runs in an.....»»
Fraudsters’ working patterns have changed in recent years
Less sophisticated fraud — in which doctored identity documents are readily spotted — has jumped 37% in 2022, according to Onfido. Fraudsters can scale these attacks on an organization’s systems around the clock. It is estimated that the curren.....»»
J. Robert Oppenheimer cleared of “black mark” against his name after 68 years
Manhattan Project physicist was infamously stripped of his security clearance in 1954. Enlarge / A young J. Robert Oppenheimer in April 1945. He led the Manhattan Project during World War II to develop the first atomic bomb. (cre.....»»
Male fruit flies found to transfer chemical to females to induce sleep, so they won"t mate with other males
A team of researchers from Bariloche Atomic Center and Fundación Instituto Leloir—IIBBA—CONICET, both in Argentina, has found that male fruit flies inject females with a chemical while mating that makes them sleep after sex so that they will not.....»»
Overclockers surpassed the elusive 9GHz clock speed. Here’s how they did it
The Intel Core i9-13900K processor just managed to reach a new world record by hitting a clock speed of over 9GHz......»»
Non-inertial torques and the Euler equation
Classical mechanics is the framework for studying motion of objects under the influence of forces. Its domain of applicability is limited to the macroscopic world (i.e., not applicable in the atomic/subatomic world) and to motion of objects with spee.....»»
Theoreticians discover why optical cavities curb the rate of chemical reactions
Chemical reactions occur on the scale of atomic vibrations—one million times smaller than the thickness of a human hair. These tiny movements are difficult to control......»»
Deconvoluting the data: Charge density distributions of electric double layers
Expanding on their recently developed electrochemical 3D atomic force microscopy (EC-3D-AFM) technique, University of Illinois Urbana-Champaign researchers have derived the depth profile of the charge density of electric double layers (EDLs). Through.....»»
ALMA successfully restarts observations after cyberattack
Forty-eight days after suspending observations due to a cyberattack, the Atacama Large Millimeter/submillimeter Array (ALMA) is observing the sky again. The computing staff has worked diligently to rebuild the affected JAO computer system servers and.....»»
Atomic structure of a staphylococcal bacteriophage using cryo-electron microscopy
Cryo-electron microscopy by University of Alabama at Birmingham researchers has exposed the structure of a bacterial virus with unprecedented detail. This is the first structure of a virus able to infect Staphylococcus epidermidis, and high-resolutio.....»»
