Trapping light with disorder
Like a pinball game in the hands of a good player, a collection of obstacles randomly positioned can be sufficient to trap light without the need for an optical cavity. By adding amplification, at no cost, a mirrorless laser—often dubbed "random la.....»»
Crucial role of peer support for African American doctoral students at predominantly white institutions
A new study conducted by researchers at George Washington University sheds light on the critical role that same-race peer groups play in the success of African American doctoral students at predominantly white institutions (PWIs). The research unders.....»»
High-resolution, nanoscale imaging method could accelerate the discovery of more durable materials
Take a photo with your phone and you might see wonderful details—leaves on a tree, strands of hair blowing in the wind. The width of that strand of hair is 100,000 nanometers wide. The best traditional laboratory microscope that uses light may capt.....»»
Ram"s U.S. sales are rebounding after incentive drive, CEO says
Light-truck brand is trying to clear inventory ahead of two new launches by year-end: the all-electric Ram REV, and the Ramcharger, a battery-powered pickup with an on-board gas generator to boost range and towing capacity......»»
Revealing study sheds light on feeling of collective loss and "Britishness" after Queen"s death
Research on the public mourning after the Queen's death offers new insights on how groups or crowds of people with a shared identity—in this case "Britishness"—navigate periods of change and uncertainty......»»
Research explores how workplace culture and social relationships are associated with workplace bullying
Workplace bullying poses a serious threat to employees' health and well-being. A recent study conducted at the University of Eastern Finland sheds new light on the impact of social relationships on workplace bullying. Workplace bullying is a complex.....»»
2025 VW ID Buzz: Heavy on the nostalgia, road; light on the range
The ID Buzz is more than a play for nostalgia. It helps VW expand into another, though, shrinking segment. VW expects the vehicle to draw buyers from minivans, crossovers and SUVs......»»
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.....»»
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.....»»
Putting out a brain on fire: Researchers map how antibodies bind in rare autoimmune disorder
Imagine you wake up in a hospital without a single memory of the last month. Doctors say you had a series of violent episodes and paranoid delusions. You'd become convinced you were suffering from bipolar disorder. Then, after a special test, a neuro.....»»
