Reflected moonlight found to make barn owls less visible to prey
A team of biology and optics researchers affiliated with a host of institutions in Spain has found that the unique undercoating of the barn owl helps to make it less visible to prey when flying under the moon and starlit skies......»»
National climate assessment offers new insights on community resilience and adaptation
A major weather event such as a hurricane or wildfire can have lasting, visible impacts on communities, but the longer-term, compounding effects of a changing climate can be harder to see. In its contributions to the recently released Fifth National.....»»
Researchers extend non-line-of-sight imaging towards longer wavelengths
Emerging technologies for non-line-of-sight imaging can detect objects even if they are around a corner or behind a wall. In new work, researchers use a new type of detector to extend this method from visible light into near and mid-infrared waveleng.....»»
Snake skulls show how species adapt to prey
By studying the skull shapes of dipsadine snakes, researchers at The University of Texas at Arlington have found how these species of snakes in Central and South America have evolved and adapted to meet the demands of their habitats and food sources......»»
Chandra catches spider pulsars destroying nearby stars
A group of dead stars known as "spider pulsars" are obliterating companion stars within their reach. Data from NASA's Chandra X-ray Observatory of the globular cluster Omega Centauri is helping astronomers understand how these spider pulsars prey on.....»»
Minnesota turkey farmers say expanded rural broadband could help detect bird flu sooner
Just over 5 miles from where folklore has long claimed Vikings scribbled Scandinavian etchings on a runestone, Erica Sawatzke surveys thousands of chirping baby birds in her long barn......»»
A Peruvian farmer is trying to hold energy giant RWE responsible for climate change—the inside story
On a crisp, sunny day high in the Peruvian Andes, two German judges gaze across a mountain lake to the towering white glaciers in the distance. Dark spots are visible on the pristine ice and, in quiet moments, the cold wind carries the sounds of crea.....»»
Silk lines help pirate spiders trick, capture eight-legged prey
Headlamps alone illuminated the trail bisecting the Costa Rican rainforest. Having waded the black of the Tirimbina reserve so often before, Gilbert Barrantes, Laura Segura Hernández and Diego Solano Brenes knew the routine......»»
Beaver exploitation testifies to prey choice diversity of Middle Pleistocene hominins

In March 2022, a defunct part of a space rocket hurled toward the moon's surface and impacted near the Hertzsprung Crater, an enormous impact feature on the far side of the moon that is never directly visible from Earth......»»
Decoding anthocyanin impact: Genetic insights into plant defense and growth trade-offs
Anthocyanins are key pigments in plants for plant resistance to abiotic stress. It can provide photoprotection by potentially absorbing visible light and scavenging reactive oxygen species (ROS) when biotic stress occurs. However, comparative studies.....»»
Like the phoenix, Australia"s giant birds of prey rise again from limestone caves
Australia's only vulture, and a fearsome extinct eagle, are among the earliest recorded birds of prey from the Pleistocene period more than 50,000 years ago—and now Flinders University researchers are bringing them to life again......»»
Examining the role wolves play in boreal forest dynamics as they constrain beaver movements
A team of land managers at the University of Minnesota, working with a colleague at the University of Manitoba, has learned more about the role wolves play in boreal forest dynamics as they prey on beavers. In their study, published in Proceedings of.....»»
Orkney"s lost tomb—how researchers made the Neolithic discovery
Orkney in the north of Scotland is renowned for its remarkably well-preserved monuments. Many of these are Neolithic (10,000 BC to 2,200 BC) and consist of stone circles and chambered tombs, which are still highly visible in the landscape. Chambered.....»»

Webb and Hubble combine to create most colorful view of universe
NASA's James Webb Space Telescope and Hubble Space Telescope have united to study an expansive galaxy cluster known as MACS0416. The resulting panchromatic image combines visible and infrared light to assemble one of the most comprehensive views of t.....»»
Vampire viruses prey on other viruses to replicate themselves—and may hold the key to new antiviral therapies
Have you ever wondered whether the virus that gave you a nasty cold can catch one itself? It may comfort you to know that, yes, viruses can actually get sick. Even better, as karmic justice would have it, the culprits turn out to be other viruses......»»
Team develops new method for communicating around arbitrary opaque walls
Information transfer in free space using ultraviolet, visible, or infrared waves has been gaining interest because of the availability of large bandwidth for high-data-rate communication. However, the presence of opaque occlusions or walls along the.....»»
HAARP artificial airglow may be widely visible in Alaska
Alaskans and visitors may be able to see an artificial airglow in the sky created by the High-frequency Active Auroral Research Program during a four-day research campaign that starts Saturday......»»
Raven: Open-source CI/CD pipeline security scanner
Raven (Risk Analysis and Vulnerability Enumeration for CI/CD) is an open-source CI/CD pipeline security scanner that makes hidden risks visible by connecting the dots across vulnerabilities woven throughout the pipeline that, when viewed collectively.....»»
