As of 2024, Dias has had five of his research papers retracted, and five other papers have received an expression of concern. [271] [272] Victor Ninov (US), a nuclear chemist formerly at Lawrence Berkeley National Laboratory, was dismissed from his position after falsifying his work on the discovery of elements 116 and 118. [273] [274]
For example, the light-second, useful in astronomy, telecommunications and relativistic physics, is exactly 299 792 458 metres or 1 / 31 557 600 of a light-year. Units such as the light-minute, light-hour and light-day are sometimes used in popular science publications. The light-month, roughly one-twelfth of a light-year, is also used ...
The International Space Station is a platform for scientific research that requires one or more of the unusual conditions present in low Earth orbit (for example microgravity, -radiation and extreme temperatures). The primary fields of research include human research, space medicine, life sciences, physical sciences, astronomy and meteorology.
A study of 25 crowdsourced ideas aimed at reducing political polarisation in the United States is published in the journal Science. [451] Scientists build the world's smallest quantum computer using a single photon. [452] [453] 19 October – Researchers develop a plant-based food supplement to protect bees' brains from neurotoxins. [454] 23 ...
Light-year: 63 241 — Distance light travels in one Julian year (365.25 days) — Oort cloud: 75 000: ± 25 000: Distance of the outer limit of Oort cloud from the Sun (estimated, corresponds to 1.2 light-years) — Parsec: 206 265 — One parsec. The parsec is defined in terms of the astronomical unit, is used to measure distances beyond the ...
The Einsteinhaus on the Kramgasse in Bern, Einstein's residence at the time. Most of the papers were written in his apartment on the first floor above the street level. At the time the papers were written, Einstein did not have easy access to a complete set of scientific reference materials, although he did regularly read and contribute reviews to Annalen der Physik.
Cavendish experiment (1798): Henry Cavendish's torsion bar experiment measures the force of gravity in a laboratory. Double-slit experiment (c.1805): Thomas Young shows that light is a wave in his double-slit experiment.
6 February: Successful launch of the Falcon Heavy, the most powerful rocket since the Space Shuttle program. [59]2 February – A study published in the journal Science by researchers from the United States Geological Survey and the University of California, Santa Cruz reports the severe degradation of the health of polar bears in the Arctic, due to the effects of climate change.
