- A newly modified atomic clock won’t lose or gain a second for 15 billion years. This timepiece is about three times more precise than an earlier version.
- These atoms approached — and got oh so very close — to absolute zero.
- A new type of mirror is selective in the light it reflects. It allows some wavelengths of radiation to pass through, while others bounce off.
- By watching for light’s ‘echoes,’ physicists think they can retrieve information being relayed by or as light. It could make it possible for astronomers to view distant objects without having to see the light they cast off.
- In March 2014, scientists claimed to have found the first echoes of the Big Bang — ripples in the very fabric of space. A new analysis shows the experts were mistaken. Dust appears to explain the confusion.
- A newfound subatomic particle should allow scientists to better understand the strong force that holds together the nucleus of every atom.
- NASA released details of the new, more flexible apparel being designed for long-distance travelers — such as those bound for another planet.
- An experiment with beads offers support for the claim that a rare type of lightning may accompany some quakes.
- A novel material can alter how easy it is to change data stored on it, based on temperature. One immediate application: more secure hard drives for computing.
- A new analysis suggests humans are not alone in the universe. Our galaxy alone may host billions of Earth-like planets, ones able to support life as we know it.
