Instead of a traditional solid glass core, the newly-developed optical fibers feature a core of air surrounded by a meticulously engineered glass microstructure...
Each spring, billions of Bogong moths (Agrotis infusa) escape hot conditions across southeast Australia by migrating up to 1,000 km to a place that they...
In new research, astronomers used NASA’s IXPE (Imaging X-ray Polarimetry Explorer) to observe a highly relativistic jet emanating from the blazar BL...
Neurons communicate by firing electrical pulses, but scientists have found hints that neurons may transmit light as well. Researchers at the University...
In general relativity, a gravitational white hole is a hypothetical region of space that cannot be entered from outside. It is the reverse of a black hole...
The structure of optical rotatum follows a logarithmic spiral — a signature that is commonly seen in the pattern formation of seashells and galaxies,...
The Lyman-apha light from JADES-GS-z13-1 has taken nearly 13.47 billion years to reach us, as it dates back to just 330 million years after the Big Bang.

Physicists at MIT have directly stimulated atoms in an antiferromagnetic material using a terahertz laser, a light source that oscillates more than a trillion...
Bright, twisted light can be produced thanks to nanostructured filaments with twisted geometry, according to scientists at the University of Michigan.
Planck’s...
A team of researchers at Cornell University has created a new class of magnetically controlled microscopic robots (microbots) that operate at the visible-light...
In a new paper published today in the journal Optica, physicists describe how a laser beam can be made to cast a shadow that behaves as any other ordinary...
In their experiments, physicists at the University of Bonn and the University of Kaiserslautern-Landau observed the dimensional crossover from one to two...
Typically, plants grow in crowded environments, where neighboring plants shade each other while competing for light. The presence of neighbors varies over...
Tachyons are hypothetical particles that always travel faster than light. Until recently, they were generally regarded as entities that did not fit into...
Metal-free organic 3-bromo-2-thienyl diketones exhibit fast and highly efficient room-temperature phosphorescence with high color purity under various...
