Climate models can predict decadal rainfall variations on Tibetan Plateau
Summer rainfall on the Tibetan Plateau is highly predictable on multiyear timescales in large ensemble predictions, according to a research team led by Zhou Tianjun from the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences......»»
Underwater ancient cypress forest offers clues to the past
When saber-toothed tigers, woolly mammoths and giant sloths roamed North America during the last Ice Age about 18,000 to 80,000 years ago, the Gulf Coast's climate was only slightly cooler, more similar to regions to the north like Missouri and North.....»»
Oldest human traces from the southern Tibetan Plateau in a new light
Stone tools have been made by humans and their ancestors for millions of years. For archaeologists, these rocky remnants—lithic artifacts and flakes—are of key importance. Because of their high preservation potential, they are among the most comm.....»»
What causes tropospheric ozone pollution over northern Tibetan Plateau?
Atmospheric ozone, which can regulate the amount of incoming ultraviolet radiation on the Earth's surface, is important for the atmospheric environment and ecosystems. Tropospheric ozone, primarily originating from photochemical reactions, is the thi.....»»
New detector finds gamma rays from surprising cosmic sources
Astrophysicist Cao Zhen opens a steel hatch on a windswept Tibetan Plateau and climbs down a ladder into inky darkness. His flashlight picks out a boat floating on a pool of purified water above thousands of glittering orbs the size of beachballs......»»
Highest Ever Energy Light Captured By Chinese Mountain Observatory
sciencehabit writes: Using an observatory on the edge of the Tibetan Plateau, astronomers have spotted the highest energy light ever, gamma ray photons up to 1.4 petaelectronvolts (PeV). They have traced these extreme photons back to a dozen of their.....»»
Glyphosate inhibits symbiotic bacteria in beetles
Saw-toothed grain beetles live in a symbiotic association with bacteria. Their bacterial partners provide important building blocks for the formation of the insect's exoskeleton, which protects the beetles from their enemies as well as from desiccati.....»»

Shuvuuia: A dinosaur that hunted in the dark
Today's 10,000 species of birds live in virtually every habitat on Earth, but only a handful have adaptations enabling them to hunt active prey in the dark of night. Scientists have long wondered whether theropod dinosaurs—the group that gave rise.....»»
Newly identified saber-toothed cat is one of largest in history
A giant saber-toothed cat lived in North America between 5 million and 9 million years ago, weighing up to 900 pounds and hunting prey that likely weighed 1,000 to 2,000 pounds, scientists reported today in a new study......»»
Researcher questions whether powered flight appeared on non-avialan dinosaurs
Powered flight in animals—that uses flapping wings to generate thrus—is a very energetically demanding mode of locomotion that requires many anatomical and physiological adaptations. In fact, the capability to develop it has only appeared four ti.....»»
The workers of yellow crazy ants can act like lazy wannabe queens, so we watched them fight
The invasive ant world is a competitive one, rife with territorial battles and colony raids. And yellow crazy ants (Anoplolepis gracilipes), one of the world's worst invasive species, have an especially interesting trait: they're the only invasive an.....»»
Evidence for glaciation predating MIS-6 in southeastern Tibet
Southeastern Tibet is one of the most glaciated regions on the Tibetan Plateau both at present and during the Quaternary. Numerical dating of glacial deposits has allowed the establishment of a provisional chronology of Quaternary glacial fluctuation.....»»
Raccoons and raccoon dogs are expected to expand their ranges in Europe
Their home ranges lie on opposite ends of the world, yet they share a common trait: The North American raccoon (Procyon lotor) and the raccoon dog (Nyctereutes procyonoides), originally a native of Asia, were both brought to Europe during the 20th ce.....»»
Tibetan Plateau will warm faster than expected
The Tibetan Plateau, known as 'the roof of the world,' has warmed more rapidly than global average in the past decades. The observed warming of the Tibetan Plateau since 1960s can be attributed to human activities, particularly greenhouse gas emissio.....»»
Skin deep: Aquatic skin adaptations of whales and hippos evolved independently
A new study shows that the similarly smooth, nearly hairless skin of whales and hippopotamuses evolved independently. The work suggests that their last common ancestor was likely a land-dwelling mammal, uprooting current thinking that the skin came f.....»»
The trouble of being tall: Giraffes and their genes
The giraffe is a truly puzzling animal. With its exceptional anatomy and suite of evolutionary adaptations, the giraffe is an outstanding case of animal evolution and physiology. Now, an international team of researchers from the University of Copenh.....»»
