A perfectly preserved ancient tree fossil has offered scientists a unique peek into a moment 42,000 years ago when the Earth’s magnetic field went haywire. The impressive study paints a picture of temporary environmental chaos, potentially influencing … Continue reading Ancient tree tells chaotic tale of Earth’s magnetic field reversal
Unlike us, many animals can see ultraviolet light. If you’re using a video screen to study their visual perception, therefore, that screen really ought to work in the UV spectrum – and a new one does exactly that.Continue ReadingCategory: ScienceTags: … Continue reading Ultraviolet TV could provide a better understanding of animals’ vision
Astronomers have more accurately measured the distance to the oldest and farthest galaxy ever detected. The light they’re seeing left the galaxy, known as GN-z11, around 13.4 billion years ago, when the universe was a cosmic toddler, and this galaxy ma… Continue reading Astronomers precisely trace distance to oldest and farthest known galaxy
Researchers at Lancaster University have developed a new material that can store energy for months, and potentially years, at a time. The material can be activated by light, and then release the pent-up energy on demand in the form of heat.Continue Rea… Continue reading Light-activated material stores potential energy for months or years
A simple home test for breast cancer and a solar energy-harvesting window made of recycled materials are the big winners of this year’s James Dyson Awards. The annual competition encourages university students to develop innovative solutions to current… Continue reading Home cancer-screen kit and UV-harvesting windows win James Dyson Awards
Atmospheric phenomena known as “sprites” and “elves” may be spectacularly illuminating the upper cloud layers of Jupiter, according to a newly published study based on data collected by NASA’s Juno spacecraft. These short-lived light displays have been… Continue reading Sprites and elves spotted lighting up Jupiter’s atmosphere
As tiny particles traveling at the speed of light, it’s going to take a serious machine to capture photons in action, and an international team of researchers have just pieced together one that is very much up for the job. Dubbed the world’s fastest UV… Continue reading World’s fastest UV camera records flying photons in real time
Ultraviolet (UV) curing lamps are crucial if you have a resin 3D printer or work with UV adhesives. Some folks line an old Amazon shipping box with foil and drop a spotlight somewhere inside. Other folks toss their work under the all-natural light source, Sol. Both options have portability and …read more
Even though we’re warned about the harmful effects of the ultraviolet (UV) rays in sunlight, they’re essential for the production of vitamin D in the body. Now, scientists are claiming that UV LEDs could serve as a safe alternative to sunlight, when th… Continue reading Ultraviolet LEDs proposed for skin-safe vitamin D production
It’s human nature to be transfixed by clouds and all the strange shapes they swirl into, but we don’t have to be limited to Earthly skies. Jupiter offers some of the best cloud-watching in the solar system, and new Hubble images remind us why, revealin… Continue reading Hubble’s stunning new snaps of Jupiter reveal fresh storms brewing
