Eocene ungulates were very selective in their feeding
A study by the UPV/EHU-University of the Basque Country into the paleodiet of extinct paleotheriidae (or pseudo horses) provides information about their feeding strategy and the environment they inhabited at the end of the Eocene. Plagiolophus was a.....»»
Noble False Widow Spider captures bats in the attic
Scientists from the Ryan Institute in NUI Galway have published the first record of a Noble False Widow spider feeding on a protected species of Pipistrelle bats in the UK......»»
The secret of mycorrhizal fungi
Fungi, specifically those that are "mycorrhizal," are natural allies of the forest because they improve tree nutrient acquisition. But which of the mycorrhizal feeding strategies yields the greatest tree diversity in a forest: strategy A (ectomycorrh.....»»
An asteroid killed dinosaurs in spring—which might explain why mammals survived
New study sheds light on why species extinction was so selective after the K-Pg impact. An international team of scientists used synchrotron radiation to image and analyze fossilized fish from the Tanis deposit in North Dakota. Some 66 mi.....»»
Ticks survive for 27 years in entomologist"s lab
Food is necessary for survival, but an East African species of ticks adapted to survive without feeding for eight years. Not only did they live for a total of 27 years, but they healthily reproduced long after the last male tick died......»»
Common plant disease found to defend its host against pests
Scientists from University of Turku observed that ergot, a common plant disease on rye, defended its host plant chemically against grass feeding insects. The ergot disease in grains spoils the yield and causes seed loss to the plant. Based on this, i.....»»
Hungry for love: Gut molecule discovered that flips the feeding-to-mating switch
On Valentine's Day, couples all over the world will enjoy romantic dinners to celebrate love and relationships. The association between nutrition and mating is not unique to humans but is reflected across species throughout the animal kingdom. Howeve.....»»
Huge Sponges Are Eating an Extinct Arctic Ecosystem
Thousands of years ago, hydrothermal vents fed worms deep below the ice. Scientists have found 300-year-old sponges feeding on the worms’ fossilized remains......»»
Japanese squirrels can consume "poisonous" mushrooms
Associate Professor Suetsugu Kenji (Kobe University Graduate School of Science) and independent photographer Gomi Koichi have observed a Japanese squirrel (Sciurus lis) routinely feeding on well-known species of poisonous toadstool mushroom, includin.....»»
New analysis leads to a fundamentally different view of supermassive black holes
In the center of most galaxies lies a supermassive black hole. Some of these are actively feeding on the gas and dust around them, expelling excess energy as powerful jets that are seen as quasars across the entire observable Universe. A new study le.....»»
Calf personality, feeding, and growth: When one style doesn"t fit all
In a natural setting, cows and nursing calves together set the feeding schedule for the calf, and calves wean gradually, completing weaning at varying ages. By contrast, in artificial rearing systems with minimal cow-calf contact, the weaning schedul.....»»
Size selective fishing can ruin chance of catching big fish in the future
Fishermen have always competed to get the biggest fish. New research show that this has a negative, long term impact on the whole ecosystem......»»
Selective membrane may cycle dual-ion batteries closer to reality
Lithium-ion batteries are relatively safe, long-lasting, fast charging and better for the environment than non-rechargeable batteries—right? Not quite. The rocking-chair mechanism that allows for commercial power storage generally uses rare earth e.....»»
Researchers find extra-pair paternity leads to cooperation in feeding and fending off threats in bird species
An international team of researchers has found that extra-pair paternity in pied flycatchers leads to cooperation between males and females in feeding and fending off threats. In their paper published in Proceedings of the National Academy of Science.....»»
Twelve for dinner: The Milky Way"s feeding habits shine a light on dark matter
Astronomers are one step closer to revealing the properties of dark matter enveloping our Milky Way galaxy, thanks to a new map of twelve streams of stars orbiting within our galactic halo......»»
Research on magnetite in salmon noses illuminates understanding of sensory mechanisms enabling magnetic perception
It's widely understood that animals such as salmon, butterflies and birds have an innate magnetic sense, allowing them to use the Earth's magnetic field for navigation to places such as feeding and breeding grounds......»»
How "Digital Twins" Are Transforming Manufacturing, Medicine and More
Time reports on virtual doppelgangers — also known as "digital twins". (Alternate URL here.) Created by feeding video, images, blueprints or other data into advanced 3-D mapping software, digital twins are being used in medicine to replicate.....»»
Directing group-free alkene dicarbofunctionalization through catalyst control
NUS chemists have developed a new "catalyst control" blueprint to overcome a longstanding challenge in the site-selective dicarbofunctionalization of unactivated alkenes, by enabling the reaction to proceed in the absence of directing or activating g.....»»
Astronomers capture black hole eruption spanning 16 times the full Moon in the sky
Astronomers have produced the most comprehensive image of radio emission from the nearest actively feeding supermassive black hole to Earth......»»
Biosensors using field-effect transistors show great promise
Demand for sensitive and selective electronic biosensors—analytical devices that monitor a target of interest in real time—is growing for a wide range of applications. They are ideal for health care within clinical settings, drug discovery, food.....»»
Scientists Discover Seaweed Species That Stops Cows from Emitting Methane
"Globally, methane is responsible for 30% of global warming. Of that, livestock, such as cattle, account for about one-third of all methane emissions," reports CBS News. But researchers discovered that feeding seaweed to cattle would reduce greenho.....»»
