Above the islands of Hawaii o n January 28, a green laser was seen piercing the night sky, silently tracing a path towards the horizon like a stutter in the Matrix’s code.
The scene was caught on camera from a telescope atop Hawaii’s tallest peak.
You can check out the scanning laser in the footage below.

Since its launch in 2020, Generative Pre-trained Transformer 3 (GPT-3) has been the talk of the town. The powerful large language model (LLM) trained on 45 TB of text data has been used to develop new tools across the spectrum — from getting code suggestions and building websites to performing meaning-driven searches. The best part? You just have to enter commands in plain language.
GPT-3’s emergence has also heralded a new era in scientific research. Since the LLM can process vast amounts of information quickly and accurately, it has opened up a wide range of possibilities for researchers: generating hypotheses, extracting information from large datasets, detecting patterns, simplifying literature searches, aiding the learning process and much more.
Powerful earthquakes hit Turkey and Syria, causing thousands of deaths in Turkey’s worst seismic event in decades. WSJ explains why the meeting of three tectonic plates under the region mean there may be more earthquakes along the faultlines.

Rheumatoid arthritis (RA), known as “immortal cancer,” is a chronic, progressive autoimmune inflammatory disease. The development and application of an RA high-sensitivity theranostics probe can help to accurately monitor the progression and realize the efficient treatment of RA.
In a study published in Advanced Science, a research group led by Prof. Zhang Yun from Fujian Institute of Research on the Structure of Matter of the Chinese Academy of Sciences developed a dual-triggered theranostics nanoprobe based on persistent luminescence nanoparticles (PLNPs) for RA autofluorescence-free imaging-guided precise treatment and therapeutic evaluation.
The researchers first prepared a renewable near-infrared (NIR)-emitting Zn1.3 Ga1.4 Sn0.3 O4:0.5%Cr3+, 0.3%Y3+ (ZGSO) PLNPs by a facile mesoporous silica template method.
SpaceX is a big step closer to sending its giant Starship spacecraft into orbit, completing an engine-firing test at the launch pad on Thursday.
Thirty-one of the 33 first-stage booster engines ignited simultaneously for about 10 seconds in south Texas. The team turned off one engine before sending the firing command and another engine shut down — “but still enough engines to reach orbit!” tweeted SpaceX’s Elon Musk.
Musk estimates Starship’s first orbital test flight could occur as soon as March, if the test analyses and remaining preparations go well.
Proto is betting that companies will view their 7-foot-tall holographic projection boxes as an alternative for in-person meetings. At least a half-dozen startups and giants like Google and Microsoft already are.

Monkeyflowers glow in a rich assortment of colors, from yellow to pink to deep red-orange. But about 5 million years ago, some of them lost their yellow. In the Feb. 10 issue of Science, UConn botanists explain what happened genetically to jettison the yellow pigment, and the implications for the evolution of species.
Monkeyflowers are famous for growing in harsh, mineral-rich soils where other plants can’t. They are also famously diverse in shape and color. Monkeyflowers also provide a textbook example of how a single-gene change can make a new species. In this case, a monkeyflower species lost the yellow pigments in the petals but gained pink about 5 million years ago, attracting bees for pollination. Later, a descendent species accumulated mutations in a gene called YUP that recovered the yellow pigments and led to production of red flowers. The species stopped attracting bees. Instead, hummingbirds pollinated it, isolating the red flowers genetically and creating a new species.
UConn botanist Yaowu Yuan and postdoctoral researcher Mei Liang (currently a professor at South China Agricultural University), with collaborators from four other institutes, have now shown exactly which gene changed to prevent monkeyflowers from making yellow. Their research, published this week in Science, adds weight to a theory that new genes create phenotypic diversity and even new species.
