Physicists demonstrate transfer of ultraprecise time signals over a wireless optical channel
By bouncing eye-safe laser pulses off a mirror on a hillside, researchers at the National Institute of Standards and Technology (NIST) have transferred ultraprecise time signals through open air with unprecedented ...
US army seeks new technology to replace GPS
The US army is working to limit its dependence on GPS by developing the next generation of navigation technology, including a tiny autonomous chip, the director of the Pentagon's research agency said Wednesday.
Squid study holds hints of bacteria's role in regulating internal clock
Glowing bacteria in the tiny Hawaiian bobtail squid may shed new light on the role bacteria play in the human body to synchronize daily tasks such as sleeping and eating, and keeping the immune system healthy, research at ...
Review: Home shields you from non-Facebook tasks
When I got my first smartphone in 2010, I checked Facebook obsessively. But over time, the novelty wore off and opening Facebook's app to check photos, links and posts from friends turned into a chore.
Healing by the clock: In fruit flies, intestinal stem-cell regeneration fluctuates with the time of day
Circadian rhythms keep time for all living things, from regulating when plants open their flowers to foiling people when they try to beat jet lag. Day-night cycles are controlled through ancient biological ...
Symbiotic bacteria program daily rhythms in squid using light and chemicals
Glowing bacteria inside squids use light and chemical signals to control circadian-like rhythms in the animals, according to a study to be published on April 2 in mBio, the online open-access journal of the American Societ ...
Hong Kong light pollution 'one of world's worst'
Hong Kong is one of the world's worst cities for light pollution with night skies around 1,000 times brighter than globally accepted levels, researchers said Wednesday ahead of this year's Earth Hour event.
Putting the clock in 'cock-a-doodle-doo'
Of course, roosters crow with the dawn. But are they simply reacting to the environment, or do they really know what time of day it is? Researchers reporting on March 18 in Current Biology have evidence that p ...
Plants let chloroplasts know the time
(Phys.org) —Plant cells communicate information about the time of day to their chloroplasts, the part of their cells that underpins all agricultural productivity on Earth, researchers at the University ...
Tiny piece of RNA keeps 'clock' running in earliest stages of life
New research shows that a tiny piece of RNA has an essential role in ensuring that embryonic tissue segments form properly.
Explainer: what is GPS?
It's a device used widely in cars, on smartphones and in fitness devices. But what exactly is GPS, and how is it able to pinpoint our exact location anywhere on Earth?
Researchers discover a way to avoid decoherence in a quantum system
Dragonflies, as climate change indicators
Monitoring communities of climate sensitive species, such as insects, could enable scientists to develop indicators for climate change effects on biodiversity and help devise policies to protect it.
