Quantum energy exchange: Exploring light fields and a quantum emitter
A new study in Physical Review Letters illuminates the intricacies of energy exchanges within bipartite quantum systems, offering profound insights into quantum coherence, pure dephasing effects, and the potential impact on future quantum technologie.....»»
Photosynthesis is under threat in an increasingly warm world, says researcher
The basis of all life on Earth is photosynthesis. So, what happens if it is disrupted? Today, advanced measurement tools can reveal how climate change is affecting plants' ability to process the energy from sunlight......»»
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.....»»
Understanding the relationship between food waste, climate change and an aging population
Producing food and getting it to people's plates entails a significant expenditure of energy and resources. Unfortunately, approximately one third of all food produced globally is not consumed and discarded. Hence, to build sustainable societies, it.....»»
Novel quantum lidar achieves high-sensitivity wind detection
A research team has proposed a wind sensing lidar theory based on up-conversion quantum interference and successfully developed a prototype. Their work is published in ACS Photonics......»»
Physicists uncover universal non-equilibrium quantum dynamics in randomly interacting spin models
A new study has uncovered the universal dynamics far from equilibrium in randomly interacting spin models, thereby complementing the well-established universality in low-energy equilibrium physics. The study, recently published in Nature Physics, was.....»»
Photonic computing method uses electromagnetic waves to rapidly solve partial differential equations
In the fields of physics, mathematics, and engineering, partial differential equations (PDEs) are essential for modeling various phenomena, from heat diffusion to particle motion and wave propagation. While some PDEs can be solved analytically, many.....»»
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.....»»
Better ocean connectivity boosts reef fish populations, finds study
Research led by the University of Oxford has found that oceanographic connectivity (the movement and exchange of water between different parts of the ocean) is a key influence for fish abundance across the Western Indian Ocean (WIO). The findings are.....»»
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......»»
New benchmark helps solve the hardest quantum problems
From subatomic particles to complex molecules, quantum systems hold the key to understanding how the universe works. But there's a catch: when you try to model these systems, that complexity quickly spirals out of control—just imagine trying to pre.....»»
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.....»»
