Amateur Scientist: Listening to Light
Over the years I’ve designed many electronic circuits that transform steady (DC) or modulated (AC) beams of light into sound. These circuits have many applications, some of which are described here. The post Amateur Scientist: Listening to Light a.....»»
Satellite-derived data on artificial light at night indicate rapidly increasing industrial activities in the Arctic
More than 800,000 km2 of the Arctic were affected by human activity in 2013, according to an analysis of satellite-derived data on artificial light at night. On average, 85% of the light-polluted areas are due to industrial activities rather than urb.....»»
How plants compete for light: Researchers discover new mechanism in shade avoidance
Plants that are close together do everything they can to intercept light. This "shade avoidance" response has been extensively researched. It is therefore even more remarkable that researchers from the laboratory of Molecular Biology at Wageningen Un.....»»
Researchers to explore light and ultrasound therapy for melanoma treatment in pigs
Texas A&M University researchers are collaborating on a new project that studies how ultrasound and light can treat melanomas in pigs......»»
All-optical switch device paves way for faster fiber-optic communication
Modern high-speed internet uses light to quickly and reliably transmit large amounts of data through fiber-optic cables, but currently, light signals hit a bottleneck when data processing is necessary. For that, they must convert into electrical sign.....»»
Saturday Citations: Brown dwarf actually brown dwarfs; the adaptability of ice-age humans; archaeologists excited
This week, researchers discovered a near-Earth microquasar that sheds new light on sources of relativistic outflows. Doctors reported finding a triphallic gentleman. And neuroscientists reported on modest cognitive boosts from short (or "acute," in c.....»»
Controlling sound waves with Klein tunneling improves acoustic signal filtration
In the context of sensory modalities, eyes work like tiny antennae, picking up light, electromagnetic waves traveling at blistering speeds. When humans look at the world, their eyes catch these waves and convert them into signals the brain reads as c.....»»
Autoliv"s Q3 profits meet expectations as supplier outperforms global market
The safety equipment supplier's third-quarter sales decreased 0.8 percent in an overall market where global light vehicle production was down 4.8 percent......»»
Physicists show that neutron stars may be shrouded in clouds of axions
A team of physicists from the universities of Amsterdam, Princeton and Oxford have shown that extremely light particles known as axions may occur in large clouds around neutron stars. These axions could form an explanation for the elusive dark matter.....»»
New study sheds light on lily toxicity in cats—outpatient treatment may be viable option
A study published recently in the Journal of the American Veterinary Medical Association has revealed new insights into the treatment of cats exposed to toxic lilies, offering hope for pet owners facing this common household hazard......»»
A look into cloudy liquids: New method makes the expansion of turbid drops in water visible
When driving though a bank of fog, car headlights are only of limited help as the light is scattered by the water particles suspended in the air. The situation is similar when you try to observe the inside of a drop of milk in water or the internal s.....»»
Visible light energy yields two-for-one deal when added to carbon dioxide recycling process
By combining visible light and electrochemistry, researchers have enhanced the conversion of carbon dioxide into valuable products and stumbled upon a surprising discovery. The team found that visible light significantly improved an important chemica.....»»
Democrats and Republicans agree on one thing: Censoring hate speech
There is strong disagreement in the United States as to whether, when and how much hate speech should be censored when posted on social media platforms. Democrats and Republicans, in particular, often argue about this question, especially in light of.....»»
Cryo-electron microscopy sheds light on endothelin signaling mechanisms
Endothelin is a peptide hormone known for its vasoconstrictive effects. Researchers at University of Tsukuba used cryo-electron microscopy to examine the complex structure of the endothelin receptor and G protein, which are crucial for signal transdu.....»»
Second exoplanet detected orbiting an early G-type star
Astronomers report the detection of a second exoplanet orbiting a G-type star known as TIC 393818343, located some 300 light years away. The newfound alien world is about three times less massive than Jupiter. The finding was detailed in a research p.....»»
5 great Hulu shows that are perfect to stream for the fall

Hubble captures intricacies of R Aquarii, a symbiotic binary star roughly 700 light-years from Earth
The NASA/ESA Hubble Space Telescope has provided a dramatic and colorful close-up look at one of the most rambunctious stars in our galaxy, weaving a huge spiral pattern among the stars. Hubble's images capture its details and its evolution is featur.....»»
Adaptive ferroelectric materials show promise for energy-efficient supercomputing
Researchers have revealed an adaptive response with a ferroelectric device, which responds to light pulses in a way that resembles the plasticity of neural networks. This behavior could find application in energy-efficient microelectronics......»»

Apple reportedly worked with China’s BYD on batteries for its car project
The Apple Car project was canceled before it even saw the light of day, and although Apple has never publicly acknowledged the project, we know a lot of details about it thanks to different insiders. Now a new report has revealed details about a part.....»»
Janus-like metasurface technology shows different optical responses according to the direction of light
Metasurface technology is an advanced optical technology that is thinner, lighter, and more capable of precisely controlling light through nanometer-sized artificial structures than conventional technologies. KAIST researchers have overcome the limit.....»»
