Detecting nanoplastics in fractions of a second using modified Raman spectroscopy
Microplastics are tiny, barely visible plastic particles that can harm the environment, for example, if they are eaten by animals. However, it has been difficult to assess the effect of even smaller particles, which can hardly be detected using conve.....»»
JWST"s MIRI instrument is having problems again
Last week, NASA shared a blog post saying they detected a sensor glitch associated with the James Webb Space Telescope's Mid-Infrared Instrument (MIRI). For some reason, the sensor for MIRI's Medium Resolution Spectroscopy (MRS) is receiving less lig.....»»

Lossless light: Revisiting Raman gain and amplification in a silicon photonic platform
Stars emit light that travels through empty space without significant attenuation. The visual signal is essentially lossless until detected. After many years and billions of kilometers, starlight-photons may eventually encounter the earth's atmospher.....»»
We might be able to find evidence for modified gravity in the Earth
Testing the possibility of models of gravity different from general relativity may be closer to home than we think. In a paper published on the arXiv preprint server, a team of researchers has proposed that we might be able to use seismic motions in.....»»
NASA satellite"s elusive green lasers spotted at work
The green light streaking across the cloudy sky was something that Daichi Fujii had never seen before. The museum curator's motion-detecting cameras were set up near Japan's Mount Fuji to capture meteors, allowing him to calculate their position, bri.....»»
How different were galaxies in the early universe?
An array of 350 radio telescopes in the Karoo desert of South Africa is getting closer to detecting the "cosmic dawn"—the era after the Big Bang when stars first ignited and galaxies began to bloom......»»
Genetically Modified Houseplants Are Coming to Clean Your Air
Neoplants says its pothos has superior purification properties—but you’ll still need a lot of them to get the job done......»»
Data-backed insights for future-proof cybersecurity strategies
