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.....»»
New silica-based adsorbent developed for selective separation of radioactive strontium from acidic medium
Prof. Huang Qunying's team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a novel inorganic silica-based adsorbent for the highly selective separation of strontium from acidic medium. The results were p.....»»
56 million-year-old Eocene global warming may indicate a wetter future
Modeling of Earth's response to global warming has suggested dry regions will become more arid and wet regions will experience more precipitation, with an uneven distribution of moisture in the atmosphere. With enhanced seasonality, there will likely.....»»
New protein scaffolds for assembling multi-enzyme systems with unprecedented control
Cell-free biocatalysis is being increasingly used as a substitute for conventional chemical catalysts, given that enzymes (biological catalysts) are more sustainable and selective in the manufacture of valuable chemicals. Chemical biomanufacturing ha.....»»
A jaw-dropping conundrum: Why do mammals have a stiff lower jaw?
From the 20-foot-long jawbones of the filter-feeding blue whale to the short, but bone-crushing, jaws of the hyena and the delicate chin bones of a human, the pair of lower jawbones characteristic of mammals have evolved with amazing variation......»»
Researchers estimate that gray whales off Oregon Coast consume millions of microparticles per day
Oregon State University researchers estimate that gray whales feeding off the Oregon Coast consume up to 21 million microparticles per day, a finding informed in part by poop from the whales......»»
NASA wants to identify phytoplankton species from space. Here"s why
They're small, but they're mighty. From producing oxygen we breathe to soaking up carbon we emit to feeding fish we eat, tiny phytoplankton are a crucial part of ocean ecosystems and essential to life as we know it on Earth. To give us a new view of.....»»
How proteins protect mammalian sperm on their way to the egg cell
Mammalian seminal fluid contains a variety of proteins secreted by the accessory sex glands that are important for the processes involved in fertilization. One of these proteins, which is found in ungulates—and in particularly large quantities in b.....»»
New technologies reveal the impact of circular economy on threatened species such as the Egyptian vulture
If urban landfills disappear under the new European regulation, some endangered birds such as the Egyptian vulture will need alternatives to their feeding patterns in order to survive in the future......»»
Study describes ancient New Zealand dolphin with tusk-like teeth
University of Otago, New Zealand, researchers have described a new genus and species of dolphin from the late Oligocene. In their paper, "A new dolphin with tusk-like teeth from the late Oligocene of New Zealand indicates evolution of novel feeding s.....»»
Underwater noise shown to disturb feeding behavior of marine organisms
Many marine organisms, such as fish, marine mammals and crustaceans, produce and use sound to navigate, reproduce, detect prey and avoid predators. However, anthropogenic sound, for example from the construction and operation of offshore wind farms,.....»»
Buzzworthy: Honeybee health blooming at federal facilities across the country
While judges, lawyers and support staff at the federal courthouse in Concord, New Hampshire, keep the American justice system buzzing, thousands of humble honeybees on the building's roof are playing their part in a more important task—feeding the.....»»
Using AI to push the boundaries of wildlife survey technologies
In their research, associate professor from the NRS Department Tiejun Wang and his master's student Zijing Wu developed an AI-model to automatically locate and count large herds of migratory ungulates (wildebeest and zebra). They used their method in.....»»
Engineering a new way to feed gorillas
A team of Georgia Tech researchers has built an automatic feeding machine for gorillas at Zoo Atlanta that allows the primates to more naturally forage for food. Their ForageFeeder replaces the zoo's previous feeding protocols, which had staff delive.....»»
New membrane design allows selective and near-frictionless ion transport
Ion-transport membranes are vital components of clean-energy technologies, such as CO2 electrolyzers, water electrolyzers, fuel cells, redox flow batteries and ion-capture electrodialysis. These membranes must screen out specific substances to preven.....»»
A dual symbiosis supports cuticle formation in wood-feeding beetles
Beetles usually rely on the help of bacterial partners to survive. These symbioses can have different functions. Bacterial symbionts may help digest plant material, make the beetles more resistant to plant defenses, or provide supplemental nutrients.....»»
What role do forests play as a feeding habitat for honeybees?
Bees are generally associated with flowering meadows rather than with dense forests. Woodland, however, is considered the original habitat of the western honeybee (Apis mellifera), as it offers nesting sites in the form of tree cavities. Researchers.....»»
Fossils reveal the long-term relationship between feathered dinosaurs and feather-feeding beetles
New fossils in amber have revealed that beetles fed on the feathers of dinosaurs about 105 million years ago, showing a symbiotic relationship of one-sided or mutual benefit, according to an article titled "Symbiosis between Cretaceous dinosaurs and.....»»
Professor unearths the ancient fossil plant history of Burnaby Mountain
New research led by Simon Fraser University paleobotanist Rolf Mathewes provides clues about what plants existed in the Burnaby Mountain area (British Columbia, Canada) 40 million years ago during the late Eocene, when the climate was much warmer tha.....»»
Peptide that signals feeding suppression in jellyfish identified
A team affiliated with multiple institutions in Japan has identified a peptide that signals feeding suppression in jellyfish. In their study, reported in Proceedings of the National Academy of Sciences, the group dissected sample jellyfish and studie.....»»
Porous material for selective trapping of carbon dioxide and toxic gases
A research team at POSTECH has successfully synthesized a new hybrid material that effectively captures carbon dioxide and other toxic gases through its porous organic-inorganic structure......»»
