Daylight saving time in the United States ends at 2 a.m. local time on Sunday, Nov. 1, when clocks move back one hour to standard time. The change will not affect trick-or-treating light levels on Halloween, but will shift sunset earlier starting the next day. Standard time will remain until clocks spring forward again on March 14, 2027, under the long-standing twice-yearly schedule set by the Uniform Time Act of 1966.
A recurring public debate persists in the United States and parts of Canada over whether to keep permanent standard time or permanent daylight saving time, eliminating the twice-yearly clock change. No legislative resolution has been reached, and the biannual time shift remains in effect.
The Verge's Victoria Song tested Death Clock, an app that estimates users' death date and biological age using an optional blood panel bundled with its $69 annual subscription. The app recommends numerous add-on tests and purchases, including thyroid, heart and liver panels, a continuous glucose monitor, smart scale, blood pressure monitor, VO2 max evaluation, liver ultrasound, cervical cancer screening, coronary CT angiography, APOE testing and colonoscopy, claiming these could add years to a user's projected lifespan.
Daylight saving time in the US ends at 2 a.m. on Sunday, Nov. 1, when clocks shift back an hour to standard time. It will resume at 2 a.m. on Sunday, March 14, 2027, under the twice-yearly schedule set by the Uniform Time Act of 1966.
A reviewer testing Hatch's contactless Sleep Clock compared its sleep duration and stage readings against an Apple Watch Series 12 and Oura Ring 5, finding duration estimates mostly aligned but sleep-stage data more variable. The device requires precise placement 2 to 4 feet from the sleeper with a clear line of sight, and it only tracks the person closest to it, unlike dual-sleeper systems such as Eight Sleep.
In his 1377 French commentary on Aristotle's On the Heavens, theologian Nicole Oresme compared the regular motion of the heavens to a self-running mechanical clock set in motion by God, rather than relying on Aristotle's idea of souls or intelligences guiding the spheres. However, Oresme also wrote that God may have appointed angels to continue moving the heavens, complicating any straightforward reading of his clock analogy as a precursor to later 'clockmaker God' deism.
A large-scale study reported in Nature found that disruptions to the body's internal clock, or circadian rhythm, are associated with roughly one in four cases of depression. The research adds to a growing body of evidence pointing toward a distinct 'circadian depression' subtype, though the findings stop short of establishing causation.
A quirk in Apple's Clock app has resurfaced online: rapidly scrolling the hour and minute wheels when setting an alarm hits a hard stop at 4:39 (16:39 in 24-hour format), rather than scrolling infinitely. The behavior doesn't restrict users from actually setting an alarm for any time; it only affects how far the scroll wheel spins before snapping to an end.
Researchers in Singapore have created an atomic clock capable of measuring time with unprecedented accuracy, reaching the 19th decimal place. This new device surpasses all previous records for precision in timekeeping.
Scientists working on a nuclear clock based on the thorium-229 isotope described how they processed fluorescence signal data to measure the transition's frequency accurately. Their method corrects for leftover excited-state population from prior measurements and for fluctuations in the vacuum-ultraviolet excitation power used to probe the nuclear transition.
Researchers describe a laser interrogation system built around a commercial frequency-quadrupled diode laser that reaches roughly 500 mW at 296.8 nm, used to probe a thorium-229-doped crystal sample. The setup combines offset-frequency phase locking and Pound-Drever-Hall stabilization to a reference cavity, with a photomultiplier tube detecting fluorescence signals inside a vacuum chamber, and the clock laser's frequency also compared against an optical frequency comb.
Owners of the Lenovo Smart Clock Essential began losing the weather display from their devices' screens during August and September, leaving only the time showing. Within the last day, users on Reddit and in reader comments have reported that the weather information has started reappearing on their devices.
