In the fall, the clocks “fall back” one hour at 2:00 a.m., instantly becoming 1:00 a.m.
This week, we will lose an hour on Sunday March 9. We will gain an hour on Sunday November 2.
Daylight-saving time was originally concocted as a way to save energy in the evenings, and was implemented during World War I in Germany.

Why time passes is one of the biggest mysteries in physics, as the fundamental laws of nature don’t reflect a difference between moving forward and backward in time. In a new paper, researchers have shown that time might actually be able to run in two directions, meaning we might have a twin universe where time runs opposite our universe’s. Let’s take a look.

Discover Manus, the world’s first fully autonomous AI agent that can perform complex tasks independently without human guidance.
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.
New dynamic robots now spin instant bridges and delicate grippers from polymer fibers.
This new spider-inspired robot can spin its own components and tools on demand using heated polymer technology.
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.
