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
When suturing wounds within the body, there’s a risk of damaging the tissue, and of the development of infections. A new type of surgical glue could reduce the need for sutures, though, plus it could close wounds faster while also delivering medication… Continue reading Rubbery bioadhesive could speed surgeries and boost wound healing
A NASA spacecraft has observed a pulsing glow coming from Mars. Huge spots of ultraviolet light were seen in the night sky, pulsing with uncanny regularity – exactly three times every night. The find highlights (literally) the atmospheric processes and… Continue reading Seasonal ultraviolet light pulses in Martian skies three times a night
Powdery mildew is a widespread fungal disease that attacks many crops. And while it typically has to be treated using fungicides, special ultraviolet light-emitting robots could soon prove to be a better way to go.Continue ReadingCategory: Robotics, Te… Continue reading UV-emitting robots roam vineyards to kill fungus
Germicidal lamps are designed to destroy viruses and bacteria using ultraviolet light. But not just any UV light will work, and I came across an example of a lamp that was advertised as germicidal but a few things just weren’t right about it.
I ordered the UV-C germicidal LED lamp …read more

Plant-based bioplastics are already a more eco-friendly alternative to their petroleum-based counterparts. Now, scientists have created a clear bioplastic film that not only blocks harmful ultraviolet radiation, but that is also more airtight than trad… Continue reading UV-blocking bioplastic is also super-airtight
It’s almost a certainty that we’re not alone in the universe, but so far direct evidence has eluded us. While we have some idea about what kinds of signs to look for on other planets, many of these can also be created under natural processes…. Continue reading New NASA mission launch aims to reduce false-positives in search for life
Mars is a pretty inhospitable place, and NASA recently ruined the fun by showing that it’s just not feasible to terraform the entire planet. But what about just certain parts of it? Now, researchers from Harvard have shown that thin layers of… Continue reading Harvard study says an inch of silica aerogel could make patches of Mars liveable
