Published Bird feeding helps small birds fight infection
(via sciencedaily.com) Original source Seeds and fat balls do more than just fill small birds' stomachs. New research from Lund University in Sweden shows that feeding during the wintertime causes birds to be healthier, since they do not have to expend as much energy fighting infections.
Published How electricity can heal wounds three times as fast
(via sciencedaily.com) Original source Chronic wounds are a major health problem for diabetic patients and the elderly -- in extreme cases they can even lead to amputation. Using electric stimulation, researchers have developed a method that speeds up the healing process, making wounds heal three times faster.
Published A solar hydrogen system that co-generates heat and oxygen
(via sciencedaily.com) Original source Researchers have built a pilot-scale solar reactor that produces usable heat and oxygen, in addition to generating hydrogen with unprecedented efficiency for its size.
Published Temperature, drought influencing movement of Plains bison
(via sciencedaily.com) Original source Temperature and severe drought can drive movement among herds of Plains bison, says a recent study. The team's GPS-backed data suggests that conserving the once-endangered species could depend on accounting for the climate extremes that Plains bison will likely encounter moving forward.
Published Software to untangle genetic factors linked to shared characteristics among different species
(via sciencedaily.com) Original source Scientists have developed a software package to help answer key questions about genetic factors associated with shared characteristics among different species.
Published Why orchid bees concoct their own fragrance
(via sciencedaily.com) Original source The reason why male bees collect scents in pockets on their hind legs remained a mystery for a long time. As an attractant? As a wedding gift? To show off to other males? Researchers have now figured it out.
Published Scientists create high-efficiency sustainable solar cells for IoT devices with AI-powered energy management
(via sciencedaily.com) Original source Researchers have created environmentally-friendly, high-efficiency photovoltaic cells that harness ambient light to power internet of Things (IoT) devices.
Published Wildfires and animal biodiversity
(via sciencedaily.com) Original source Wildfires. Many see them as purely destructive forces, disasters that blaze through a landscape, charring everything in their paths. But a new study reminds us that wildfires are also generative forces, spurring biodiversity in their wakes.
Published Engineers devise technology to prevent fouling in photobioreactors for CO2 capture
(via sciencedaily.com) Original source A new, inexpensive technology can limit the buildup of algae on the walls of photobioreactors that can help convert carbon dioxide into useful products. Reducing this fouling avoids costly cleanouts and allows more photosynthesis to happen within tanks.
Published Oldest bat skeletons ever found described from Wyoming fossils
(via sciencedaily.com) Original source Scientists have described a new species of bat based on the oldest bat skeletons ever recovered. The study on the extinct bat, which lived in Wyoming about 52 million years ago, supports the idea that bats diversified rapidly on multiple continents during this time.
Published Timing of snowshoe hare winter color swap may leave them exposed in changing climate, study finds
(via sciencedaily.com) Original source A new study, which used 44 years of data, shows that as the globe has warmed, altering the timing and amount of snow cover, snowshoe hares' winter transformation may be out of sync with the color of the background environment; this may actually put them at a greater disadvantage.
Published Starting small and simple -- key to success for evolution of mammals
(via sciencedaily.com) Original source The ancestors of modern mammals managed to evolve into one of the most successful animal lineages -- the key was to start out small and simple, a new study reveals.
Published British flower study reveals surprise about plants' sex life
(via sciencedaily.com) Original source A study of Britain's native flowering plants has led to new insights into the mysterious process that allows wild plants to breed across species -- one of plants' most powerful evolutionary forces. When wild flowering plants are sizing up others they may often end up in a marriage between close relatives rather than neighbors, a new study has revealed.
Published Study predicts poor survival rates if Ebola infects endangered mountain gorillas
(via sciencedaily.com) Original source If infected with the Ebola virus, less than 20 percent of Africa's endangered mountain gorillas would be expected to survive more than 100 days, finds a new study.
Published Electrification push will have enormous impacts on critical metals supply chain
(via sciencedaily.com) Original source The demand for battery-grade lithium, nickel, cobalt, manganese and platinum will climb steeply as vehicle electrification speeds up and nations work to reduce greenhouse gas emissions through mid-century. This surge in demand will also create a variety of economic and supply-chain problems, according to new research.
Published Photonic filter separates signals from noise to support future 6G wireless communication
(via sciencedaily.com) Original source Researchers have developed a new chip-sized microwave photonic filter to separate communication signals from noise and suppress unwanted interference across the full radio frequency spectrum. The device is expected to help next-generation wireless communication technologies efficiently convey data in an environment that is becoming crowded with signals.
Published Researchers discover new circuit element
(via sciencedaily.com) Original source Researchers have identified a new circuit element known as a meminductor.
Published Cities will need more resilient electricity networks to cope with extreme weather
(via sciencedaily.com) Original source Dense urban areas amplify the effects of higher temperatures, due to the phenomenon of heat islands in cities. This makes cities more vulnerable to extreme climate events. Large investments in the electricity network will be necessary to cool us down during heatwaves and keep us warm during cold snaps, according to a new study.
Published Family tree of 'boring' butterflies reveals they're anything but
(via sciencedaily.com) Original source Important species often get overlooked if they lack flashy colors or charismatic behavior. This is true of euptychiine butterflies, one of the most common insects in the Amazon Rainforest that have been largely ignored by scientists and naturalists throughout the 20th century. A new study pieces together the natural history of the group, in which males can look so unlike females, they've been repeatedly mistaken for separate species, diversity has been drastically underestimated, and more than 100 unnamed species are waiting on scientific description.
Published Early crop plants were more easily 'tamed'
(via sciencedaily.com) Original source Borrowing a page from what we know about animal behavior, archaeologists say that we should reassess our understanding of the process of plant domestication.
