A story about traveling through time, literally.

When we fly, we often cross time zones, sometimes even when we drive. Imagine for a moment that this is a continuous process. Even as you walk, your zone moves just a little from one moment to another.

S assume that your personal noon is when the sun is highest. You can create the time for your own body with this calculator. ” + Give it a try. If you have an iPhone, open the included compass app to get the longitude and latitude required to set this personal clock. You can also use Google Earth with your browser to find your location and the lat and long in the bottom right.

Once upon a time there was enough technology that everybody had their own personal time zone to maximize their health and enjoyment. Yes, it seemed odd for a while that time was now considered time and location, but it did not take long to get used to everybody living in a different time zone. Sounds confusing when we are used to large time zones, but you know, so was coordinated time at one point. Just a little different way of doing things that keeps us healthier and happier.

Physicists have long attempted to find a single theory that unites quantum mechanics and general relativity.

This has been very tricky because quantum mechanics focuses on the unpredictable nature of particles at microscopic scales, whereas general relativity explains gravity as the curvature of spacetime caused by massive objects.

The two theories discuss forces existing on different scales. Bianconi employed an interesting approach to deal with this challenge. She proposes an entropic action where, instead of being a fixed background, spacetime works like a quantum operator — acting on quantum states and deciding how they change over time.

Centenarians, once considered rare, have become commonplace. Indeed, they are the fastest-growing demographic group of the world’s population, with numbers roughly doubling every ten years since the 1970s.

How long humans can live, and what determines a long and healthy life, have been of interest for as long as we know. Plato and Aristotle discussed and wrote about the ageing process over 2,300 years ago.

The pursuit of understanding the secrets behind exceptional longevity isn’t easy, however.

Rab5 is a cellular GTPase essential for endocytic clearance of invading pathogens. This study from Shino Tanaka, Hiromu Oide, Tomoko Kubori, Kohei Arasaki (Tokyo University of Pharmacy and Life Sciences) and colleagues reveals that the bacterial pathogen Legionella pneumophila ubiquitinates Rab5 to recruit a Rab5 inactivator RabGAP-5 to its phagosome, thereby excluding Rab5 and facilitating its intracellular replication.
