Birds" dazzling iridescence tied to nanoscale tweak of feather structure
The iridescent shimmer that makes birds such as peacocks and hummingbirds so striking is rooted in a natural nanostructure so complex that people are only just beginning to replicate it technologically. The secret to how birds produce these brilliant.....»»
A new theoretical development clarifies water"s electronic structure
There is no doubt that water is significant. Without it, life would never have begun, let alone continue today—not to mention its role in the environment itself, with oceans covering over 70% of Earth......»»
Observations explore radio jet of a powerful quasar
European astronomers have conducted very long baseline interferometric (VLBI) observations of a radio jet structure in a powerful quasar known as PKS 2215+020. The collected VLBI data provide important insights into the properties of this jet, sugges.....»»
How to track important changes in a dynamic network
Networks can represent changing systems, like the spread of an epidemic or the growth of groups in a population of people. But the structure of these networks can change, too, as links appear or vanish over time. To better understand these changes, r.....»»
Protected lands provide a last stand for critically endangered vultures in West Africa
Among the fastest-declining birds in the world, African vultures battle many of the problems commonly plaguing wildlife today, such as habitat loss, hunting, and poisoning, but they also face a more unique set of obstacles......»»
Stellantis CEO Carlos Tavares" compensation jumps 56% to $40M

New Zealand opens first "kiwi hospital" for injured birds
New Zealand on Friday opened its first hospital exclusively treating kiwi birds, and vets have already nursed the first patient back to health—a chick nicknamed "Splash" that tumbled into a swimming pool......»»
Birds know no borders. Nor do scientists
Over centuries, wetlands all over the world have had to give way to "more useful" types of land—seen from man's perspective......»»
Live imaging reveals key cell dynamics in 3D organ formation in Drosophila
Animal development requires successive changes in cell and tissue structures. To form complex 3D organs, cell shapes must adapt to support tissue morphogenesis. However, our understanding of how cellular structure changes are coupled with dynamic tis.....»»
LHAASO discovers giant ultra-high-energy gamma-ray bubble, identifying the first super PeVatron
The Large High Altitude Air Shower Observatory (LHAASO) has discovered a giant ultra-high-energy gamma-ray bubble structure in the Cygnus star-forming region, which is the first time that the origin of cosmic rays with energy higher than 10 Peta-Elec.....»»
Research team develops nanoscale device for brain chemistry analysis
Longstanding challenges in biomedical research such as monitoring brain chemistry and tracking the spread of drugs through the body require much smaller and more precise sensors. A new nanoscale sensor that can monitor areas 1,000 times smaller than.....»»
VPNVax: Crafting enhanced viral structure in vaccines through polymer restructuring
Generally speaking, the higher the degree of information restoration of a vaccine to a virus, the greater its potential efficacy. The virus itself is the most authentic vaccine, such as the varicella-zoster virus, which provides lifelong immunity aft.....»»
Pharmacists propose ways to increase the activity of levofloxacin and overcome bacterial resistance
The antibacterial drug levofloxacin is used to treat pneumonia, sinusitis, genitourinary infections, and other diseases. It is included in the WHO Model List of Essential Medicines. In terms of its chemical structure, it is a third-generation fluoroq.....»»
Active Directory outages can cost organizations $100,000 per day
Nearly every organization has core systems services tied to Active Directory that will go down during an outage, according to Cayosoft. Consequences of system downtime for business operations The impact of just one system being down can devastate bus.....»»
Junk DNA in birds may hold key to safe, efficient gene therapy
The recent approval of a CRISPR-Cas9 therapy for sickle cell disease demonstrates that gene editing tools can do a superb job of knocking out genes to cure hereditary disease. But it's still not possible to insert whole genes into the human genome to.....»»
Birds have been adapting to human activity for millennia, research suggests
Roughly 14,500 to 10,500 years ago, in the transition from the last glacial period, Epipaleolithic and Neolithic peoples harvesting vegetation from the wetlands of eastern Jordan created a habitat for birds that would otherwise have migrated, a new s.....»»
Stone Age "megastructure" under Baltic Sea sheds light on strategy used by Paleolithic hunters over 10,000 years ago
Archaeologists have identified what may be Europe's oldest human-made megastructure, submerged 21 meters below the Baltic Sea in the Bay of Mecklenburg, Germany. This structure—which has been named the Blinkerwall—is a continuous low wall made fr.....»»
Australia"s most at-risk bird species share some common traits
Australian birds that live on islands are among the species most at risk of extinction, a first-of-its-kind study from The Australian National University (ANU) has shown. The study is published in the journal Emu—Austral Ornithology......»»
5,000 atoms are all you need: The smallest solid-state ferroelectricity
Recent research has broken the size limitation of traditional ferroelectric effects, providing experimental evidence and theoretical simulations to confirm that a structure with as few as 5,000 atoms can still exhibit solid-state ferroelectric effect.....»»
Scientists identify genetic mechanism responsible for plant leaf diversity
Plant leaves come in many different shapes, sizes and complexities. Some leaves are large and smooth, while others are smaller and serrated. Some leaves grow in single pieces while others form multiple leaflets. These variations in leaf structure pla.....»»
Researchers identify human activities as drivers of biodiversity decline in central Mexico"s reserves
New research shows the diversity of plant and animal life in 14 tropical reserves in Mesoamerica has plummeted since 1990 as roads and cattle ranches have expanded into protected areas. Large mammals, birds, and reptiles are disappearing, while disea.....»»
