Physicists have performed an improved measurement of the free neutron lifetime using the UCNτ apparatus at the Los Alamos Neutron Science Center. Their results, published in the journal Physical Review Letters, represent a more than two-fold improvement over previous measurements. Gonzalez et al. report an improved measurement of the free …

The isotope tin-100 is of interest for nuclear structure due to its closed-shell proton and neutron configurations. It is also the heaviest nucleus comprising protons and neutrons in equal numbers. In new research, physicists from the ISOLTRAP experiment at CERN’s Isotope mass Separator On-Line (ISOLDE) facility performed direct mass measurements …

The heavens appear to move throughout the year, but that’s just because Earth is moving. The real or “proper motion” of stars and galaxies was beyond our ability to measure until fairly recently, but bigger, more powerful telescopes have helped paint a picture of an evolving universe. The European Space …

  Google is rolling out a new set of health monitoring features to Pixel phones, and they could come to more Android devices soon. That’s because Google’s new respiration and heart rate scanning tech is not based on a specialized sensor — it relies on your smartphone’s existing cameras. Like …

Facebook Ads boycott: What will be the measure of success?   The list of advertisers keeps growing — 500 and counting, according to Sleeping Giants. Much has been written about whether the advertiser boycott of Facebook Ads that kicked off today will amount to anything. It may depend on your …

A new study published in the journal Proceedings of the National Academy of Sciences reveals the link between breeding season and the hormone melatonin, made in the pineal gland in the brain during long winter nights. Castle-Miller et al have discovered how animals link the change in seasons to their …

Using mid-infrared data from the 8.2-m Subaru Telescope, a research team led by Dr. Hideaki Fujiwara, Subaru scientist at the National Astronomical Observatory of Japan, has measured the brightness and temperatures of Saturn’s main rings. This is a three-color composite image of Saturn and its rings taken January 23, 2008 …

An international team of physicists led by RIKEN researcher Stefan Ulmer has found that the magnetic moment of the antiproton is extremely close to that of the proton, with six-fold higher accuracy than before. Top: schematic of the Penning trap set-up used in CERN’s BASE experiment; a cloud of antiprotons …

Photo: Pond5 Whether your priority is looking good in a bathing suit or living to see 100, there’s one piece of information that might stand in the way: body composition. Many people overlook this important metric, or the measure of fat mass to lean tissue, including bone, muscle, ligaments, tendons and organs. …

Image: Screenshot from TechCrunch It’s been a bad few weeks for Snapchat after many people called into questioned how secure users were on the service – especially given how dismissive they were to an exploit which lead to 4.6 million usernames and phone numbers leaked, and a sudden increase in spam. However, …
