Precision machining produces tiny, light-guiding cubes for advancing info tech
Drilling with the beam of an electron microscope, scientists at the Department of Energy's Oak Ridge National Laboratory precisely machined tiny electrically conductive cubes that can interact with light and organized them in patterned structures tha.....»»
Walk or run in the rain? A physics-based approached to staying dry (or at least drier)
We've all been there—caught outside without an umbrella as the sky opens up. Whether it's a light drizzle or a heavy downpour, instinct tells us that running will minimize how wet we get. But is that really true? Let's take a scientific look at thi.....»»
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.....»»
Tracking vampire worms with machine learning
Blood samples of patients infected with a parasitic worm that causes schistosomiasis contain hidden information that marks different stages of the disease. In our recently published research, our team used machine learning to uncover that hidden info.....»»
Are self-driving cars the death of car ownership?
Plenty of companies are investing in self-driving car tech, but if that tech becomes a reality, what does it mean for car ownership?.....»»
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......»»
To the astonishment of forecasters, a tiny hurricane just sprang up near Cuba
As of Saturday evening, hurricane-force winds extended just 5 miles from the center. A hurricane so small that it could not be observed by satellite formed this weekend, surprisin.....»»
NFL Week 7 games today: schedule, channels, live streams for October 20

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.....»»
New genome reconstruction advances thylacine de-extinction efforts
New scientific milestones in the mission to reverse the extinction of the thylacine (Tasmanian tiger) are advancing University of Melbourne research and progressing potential solutions to the broader extinction crisis......»»
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.....»»
iPad mini 7 benchmarks show the tiny tablet is incredibly powerful
Apple unveiled the iPad mini 7 earlier this week, which I consider an amazing upgrade over its predecessor even though it’s practically identical to the … The post iPad mini 7 benchmarks show the tiny tablet is incredibly powerful appeare.....»»
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.....»»
Tech can help kids connect with nature and go outdoors—here are tips to make it work
Young children's lives are increasingly spent indoors. They have less access to green spaces, their parents are concerned about safety, and there's also the draw of digital entertainment. This shift away from the natural world has been evocatively na.....»»
A method to switch between optical pulling and pushing forces by altering the shape of Fermi arcs in Weyl systems
Optical forces, which act like an invisible "hand," are capable of precisely controlling tiny particles. Optical tweezers, a well-known tool, use this force to capture and manipulate small objects such as cells, bacteria, and viruses. This effect is.....»»
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.....»»
