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.....»»
Up to a billion birds collide with glass buildings every year, but architecture has solutions
At least 1,000 birds were killed in one day in early October, when they collided with a single Chicago building, McCormick Place—the largest convention center in North America. A paradigm of architectural modernism, McCormick Place was built in sta.....»»
Harnessing molecular power: Electricity generation on the nanoscale
Wave energy technology is a proven source of power generation, but there is power inherent in every molecule of liquid on Earth, even when the liquid is at rest. At the molecular scale, atoms and ions are always moving. If this nanoscale movement can.....»»

Study shows birds disperse eaten insects" eggs
Relationship patterns among flightless stick insects suggest that birds disperse the eggs after eating gravid females. Lab experiments previously suggested the possibility, but a new genetic analysis of natural populations in Japan by Kobe University.....»»
Space weather disrupts nocturnal bird migration, study finds
It's well-known that birds and other animals rely on Earth's magnetic field for long-distance navigation during seasonal migrations......»»
Night owls may earn less than early birds: Study reveals connections between circadian rhythm and income level
Researchers from the University of Oulu, Finland, have uncovered a link between internal circadian rhythm and income levels. According to the study, now published in Economics & Human Biology, individuals who tend to be more active in the evening hou.....»»
Discovery of half-million-year-old wooden structure shows we"re wrong to underestimate our ancient relatives
To most people, complex technologies separate modern humans from their ancestors who lived in the Stone Age, thousands or hundreds of thousands of years ago. In today's fast changing world, older technologies, even those from a few years ago, are oft.....»»
Meta-learning helps to estimate oceanic barrier layer structure
The oceanic barrier layer is situated between the base of the ocean's density mixed layer and the top of the isothermal layer, with its thickness fluctuations directly influencing the ocean's vertical mixing process. Changes in the barrier layer impa.....»»
Vaccine may save endangered California condors from succumbing to bird flu

Deciphering the intensity of past ocean currents
Ocean currents determine the structure of the deep-sea ocean floor and the transport of sediments, organic carbon, nutrients and pollutants. In flume-tank experiments, researchers from MARUM—Center for Marine Environmental Sciences at the Universit.....»»
Chiro-optical force observed at the nanoscale
A research group at the Institute for Molecular Science has successfully observed the left and right handedness of material structures at the nanoscale, by illuminating chiral gold nanostructures with circularly polarized light and detecting the opti.....»»
Feather-tailed possums in New Guinea were originally Aussies, according to fossil study
Analysis of Riversleigh fossils has revealed fascinating new facts about a tiny possum's ancestors. Scientists have long known that the miniature feather-tailed possums in Australia and the island of New Guinea—members of the marsupial family Acrob.....»»
Nanoscale rust: The future of magnets?

Survival of the newest: The mammals that survive mass extinctions aren"t as "boring" as scientists thought
When an asteroid hit the Earth 66 million years ago, it set off a devastating mass extinction. The dinosaurs (except for a few birds) all died out, along with lots of the mammals. But some small mammals survived, laying the groundwork for all the mam.....»»
