Differentiating right- and left-handed particles using the force exerted by light
Researchers investigated the polarization-dependence of the force exerted by circularly polarized light (CPL) by performing optical trapping of chiral nanoparticles. They found that left- and right-handed CPL exerted different strengths of the optica.....»»
Extreme polar light environment of the North and South Poles sustains biodiversity, researchers suggest
Researchers working in Finland propose that the unique light environment of the Earth's polar regions creates conditions that result in circumpolar hybrid zones around the North and the South Poles. These extreme conditions increase the synchrony of.....»»
3D field-based tracking and field experiments of octopus and fish unlock the secrets of multispecies hunting
The diving gear is on, the cameras are ready—biologist Eduardo Sampaio and his colleagues are set to go. They dive in the Red Sea, scanning left and right underwater—and wonder: Where can an octopus hunting be found? Finally, they spot one. The t.....»»
Study shows artificial light at night changes the behavior of fish, even into the next generation
Scientists have shown that light pollution—especially light in the blue spectrum—can alter the behavior of fish after only a few nights, and have knock-on effects for their offspring. The team from China has studied how female zebrafish responded.....»»
Evidence tells us voters might be convinced to accept short-term pain for long-term gain—but it will be a hard sell
In the build-up to his government's first budget, Prime Minister Keir Starmer has been setting expectations low. It will be "painful," he has warned, and a "difficult trade-off" will have to be made because of the economic inheritance left by the las.....»»
Scientists reviewed 7,000 studies on microplastics. Their alarming conclusion puts humanity on notice
It's been 20 years since a paper in the journal Science showed the environmental accumulation of tiny plastic fragments and fibers. It named the particles "microplastics.".....»»

Even the heaviest particles experience the usual quantum weirdness, new experiment shows
One of the most surprising predictions of physics is entanglement, a phenomenon where objects can be some distance apart but still linked together. The best-known examples of entanglement involve tiny chunks of light (photons), and low energies......»»
"Pirate birds" force other seabirds to regurgitate fish meals. Their thieving ways could spread lethal avian flu
It's not easy finding food at sea. Seabirds often stay aloft, scanning the churning waters for elusive prey. Most seabirds take fish, squid, or other prey from the first few meters of seawater. Scavenging is common......»»

Light momentum turns pure silicon from an indirect to a direct bandgap semiconductor
UC Irvine-led research reveals that the optical properties of materials can be dramatically enhanced—not by changing the materials themselves, but by giving the light new properties......»»
Study shows organonitrates in atmospheric particles vary with altitude
While atmospheric particles directly affect climate (e.g., cloud formation), sampling atmospheric particles aloft is practically challenging. Therefore, a full understanding of how particle composition is linked to environmental function remains limi.....»»
Harnessing exosomes and hydrogels for advanced diabetic wound healing
Diabetes, a widespread condition affecting approximately 13% of American adults, is often accompanied by complications such as impaired wound healing. If left unchecked, this can lead to severe outcomes, including the need for amputation......»»
Hubble lights the way with new multiwavelength view of galaxy NGC 1559
The magnificent galaxy featured in this NASA/ESA Hubble Space Telescope image is NGC 1559. It is a barred spiral galaxy located in the constellation Reticulum, approximately 35 million light-years from Earth. The brilliant light captured in the curre.....»»
Research highlights the unseen challenges, adaptations of adult daughters during COVID upheaval for families
A Baylor University study has shed light on the often-overlooked experiences of women doing "daughtering" in families, particularly during the COVID-19 pandemic, which created immense challenges in their relationships with parents and other family me.....»»
Astronomers just detected the biggest black hole jets ever seen—and named them Porphyrion
The largest known black hole jets, 23 million light years across, have been discovered in the distant universe. This pair of particle beams launched by a supermassive black hole is over a hundred times larger than our galaxy, the Milky Way......»»
Observers detect intraday variability of blazar 1ES 1426+42.8
Astronomers report the detection of optical intraday variability of a blazar known as 1ES 1426+42.8. The new findings, presented in a paper published in the September issue of Monthly Notices of the Royal Astronomical Society, could shed more light o.....»»
