A team from the U.S. and China has demonstrated electronic devices that can degrade and disappear on demand using nothing but moisture in the air. Most people know that electronic devices do not work particularly well in humid conditions—if your house is humid all the time, your desktop computer will not last very long, for example...

New research has enabled recent experiments to make the first measurement of the 1S – 2S atomic state transition in antihydrogen. A theoretical approach was developed for the ALPHA experiment at CERN, and provides the insight needed to make high precision spectroscopic measurements of the transition energy between the 1S and 2S energy levels. As a result, successful measurements have now been made to a precision of better than one part in a billion.

The research presented by Dr Rasmussen, Professor Niels Madsen, and Professor Francis Robicheaux, also points the way forward to even higher precision measurements of the properties of antihydrogen...

Is entanglement really necessary for describing the physical world, or is it possible to have some post-quantum theory without entanglement? In a new study, physicists have mathematically proved that any theory that has a classical limit-meaning that it can describe our observations of the classical world by recovering classical theory under certain conditions-must contain entanglement...

Predicted mean values of YAL, YoL, and YAL/YoL% from statistical models that prespecified values of healthy and unhealthy lifestyles. At comparable values of sociodemographic factors, a healthy lifestyle differed considerably from an unhealthy lifestyle in terms of YAL, YoL, disabled years, and YAL/YoL% and was associated with an absolute and relative compression of the disabled period in all race and sex groups.

New research published in the Journal of the American Geriatrics Society indicates that a healthy lifestyle may help reduce the duration of an individual’s disabled period near the end of life. In the community-based study of 5248 older adults recruited at an average age of 73 and followed for 25 years, the average number of disabled years was ~2.9 for men and 4.5 for women.
