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.....»»

Shark nets remain a deadly obstacle as humpback whales begin their East Coast migration
Whale migration season has come again to the East Coast with the first sightings being reported. Every year at this time, humpback whales migrate from feeding grounds in the Southern Ocean to the warm waters of the Coral Sea to breed and give birth t.....»»
Selective synthesis of meta isomers now possible
In a recent study published in Science, four RIKEN organic chemists have come up with a way to selectively synthesize isomers of an important group of aromatic compounds. This promises to make it possible to manufacture chemicals for drugs, fertilize.....»»
Ecotourism giving rare iguanas a sweet tooth
Ecotourists feeding grapes to rock iguanas on remote islands in the Bahamas have given them a sweet tooth and high blood sugar, researchers said Thursday, warning of unknown effects on the health of the vulnerable reptiles......»»
The answer to keeping moose populations healthy? Wolves
Predators may keep prey populations healthy by acting as a selective force against genetic diseases. A new study found that wolves select adult moose based on age and osteoarthritis, a chronic disease that can be influenced by genetics. Wolves also s.....»»
Hungry white dwarf feeding on red giant creates epic nova explosion
Astronomers using a pair of ground-based MAGIC telescopes have observed a huge nova explosion created by a pair of stars called RS Ophiuchi......»»
Sharks lose their natural response with prey if not frequently rewarded
New research studying the behavior of Port Jackson sharks has captured their astute ability to realize when the smell of natural prey doesn't lead to a feeding opportunity......»»
New strategy to control distribution of acid sites in zeolites
Zeolites are one of the shape-selective catalysts. The characteristics of zeolites, which come from the structural confinement on the molecular dimensions, are crucial for shape-selective catalysis......»»

Effects of ancient carbon releases suggest possible scenarios for future climate
A massive release of greenhouse gases, likely triggered by volcanic activity, caused a period of extreme global warming known as the Paleocene-Eocene Thermal Maximum (PETM) about 56 million years ago. A new study now confirms that the PETM was preced.....»»
Twitter decides against force-feeding users its algorithm after all
Twitter just thought better of it. The social media company most associated with the reverse-chronological feed announced Monday that it would pause recently touted plans to let users quickly swipe between Latest and Home timelines. Seemingly at issu.....»»
Whale migrations: How new UN treaty aims to protect species on the high seas
A humpback whale we tagged while it was feeding off the Western Antarctic Peninsula made a nearly 19,000 km-round trip in 265 days, traveling north from Antarctica to its breeding area off Colombia and back. Whales migrate thousands of kilometers eac.....»»
Discovery of a new catalyst for highly active and selective carbon dioxide hydrogenation to methanol
A new catalyst of Cd/TiO2, enabling 81% methanol selectivity at 15.8% CO2 conversion with the CH4 selectivity below 0.7% was discovered. The combination of experimental and computational studies show that the unique electronic properties of Cd cluste.....»»
