Investigating the difference between consent and coercion in "voluntary" resettlement in Tibet
The difference between voluntary and involuntary participation may seem clear, but a study from the Tibet Autonomous Region shows the distinction between the two can, in fact, be murky......»»
Astronomers want JWST to study the Milky Way core for hundreds of hours
To understand the universe, we need to understand the extreme processes that shape it and drive its evolution. Things like supermassive black holes (SMBHs,) supernovae, massive reservoirs of dense gas, and crowds of stars both on and off the main seq.....»»
Investigating the effects of surface treatment on the antibacterial activity of wood
Research indicates that several pathogenic bacteria can remain contagious on a range of surfaces from hours to days and weeks. While wood as a surface material is known for its antibacterial properties, dry contamination via hands has so far been poo.....»»

LIGO surpasses the quantum limit
In 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO), made history when it made the first direct detection of gravitational waves—ripples in space and time—produced by a pair of colliding black holes......»»
Working towards programmable matter: Unexpected behavior discovered in active particles
Investigating systems consisting of self-propelled particles—so-called active particles—is a rapidly growing area of research. In theoretical models for active particles, it is often assumed that the particles' swimming speed is always the same......»»

Revolutionizing radar: Integrated THz emitter for precise rotating target detection
You may not realize it, but the Doppler effect is everywhere in our lives, from tracking the speed of cars with radar to locating satellites in the sky. It's all about how waves change their frequency when a source (like a radar signal) and a detecto.....»»
A strategy for the spin-acoustic control of silicon vacancies in a 4H silicon carbide-based bulk acoustic resonator
Bulk acoustic resonators—stacked material structures inside which acoustic waves resonate—can be used to amplify sounds or filter out undesired noise. These resonators have found wide use in today's RF telecommunication, like Front-End Modules (F.....»»
Accelerating waves shed light on major problems in physics
Whenever light interacts with matter, light appears to slow down. This is not a new observation and standard wave mechanics can describe most of these daily phenomena......»»
Realizing vertical ultraviolet-B semiconductor laser diodes for high optical output
Ultraviolet (UV) rays are electromagnetic waves with wavelengths ranging from 100 to 380 nanometers (nm). These wavelengths can be classified into three regions: UV-A (315–380 nm), UV-B (280–315 nm), and UV-C (100–280 nm), with the latter two c.....»»
Waves of change: How sea-levels and climate altered the marine ecosystems at the South Pole 390–385 million years ago
During the Early-Middle Devonian period, a large landmass called Gondwana—which included parts of today's Africa, South America, and Antarctica—was located near the South Pole. Unlike today's icy conditions, the climate was warmer, and the sea le.....»»
Heat waves harm bird reproduction on agricultural lands, research suggests
Bird populations are in rapid decline across North America. While climate change is just one of the many factors influencing North American birds, its effects are significant and can interact with other stressors, such as habitat loss. A team of Univ.....»»
