Plants and microbes shape global biomes through local underground alliances
Princeton University researchers report that the organization of forests worldwide -- such as conifers in northern boreal forests or the broad-leafed trees of the tropics -- are based on the ancient relationships that plant species forged with soil-dwelling microbes such as fungi and bacteria.
These tiny organisms, known as symbionts,
Best in snow: New scientific device creates electricity from snowfall: The first-of-its-kind nanogenerator also acts as a weather station
"The device can work in remote areas because it provides its own power and does not need batteries," said senior author Richard Kaner, who holds UCLA's Dr.
New species of early human found in the Philippines
Co-author and a lead member of the team, Professor Philip Piper from The Australian National University (ANU) says the findings represent a major breakthrough in our understanding of human evolution across Southeast Asia.
The researchers uncovered the remains of at least two adults and one juvenile within the same archaeological
New evidence suggests volcanoes caused biggest mass extinction ever: Mercury found in ancient rock around the world supports theory that eruptions caused 'Great Dying' 252 million years ago.
The extinction 252 million years ago was so dramatic and widespread that scientists call it "the Great Dying." The catastrophe killed off more than 95 percent of life on Earth over the course of hundreds of thousands of years. Paleontologists with the University of Cincinnati and the China University of
Amazonian soils mapped using indicator species
Amazonia is a vast rainforest area that is both megadiverse and poorly known.
New study shows people used natural dyes to color their clothing thousands of years ago
Chemists Dr Annemarie Kramell and Professor René Csuk from MLU examined two ancient textile samples.One comes from the ancient Chinese city of Niya and was probably once part of a shirt.
What Earth's gravity reveals about climate change
This so-called time-resolved satellite gravimetry makes it possible, among other things, to monitor the terrestrial water cycle, the mass balance of ice sheets and glaciers or sea-level change, and thus to better understand the mechanisms of the global climate system, to assess important climatic trends more precisely and to predict
Ice Ages occur when tropical islands and continents collide: Collisions in tropics expose rocks that take up carbon dioxide, cooling normally balmy Earth
The key trigger, they say, is mountain formation in the tropics as continental land masses collide with volcanic island arcs, such as the Aleutian Islands chain in Alaska.
Melting glaciers causing sea levels to rise at ever greater rates
Glaciers have lost more than 9,000 billion tons (that is 9,625,000,000,000 tons) of ice between 1961 and 2016, which has resulted in global sea levels increasing by 27 millimeters in this period..
Woolly mammoths and Neanderthals may have shared genetic traits: Findings point to molecular resemblance in climate adaptation traits of the two species
The research attributes the human-elephant relationship during the Pleistocene epoch to their mutual ecology and shared living environments, in addition to other possible interactions between the two species.
The study was led by Prof. Ran Barkai and Meidad Kislev of TAU's Department of Archaeology and Ancient Near Eastern Cultures and
Researchers remove harmful hormones from Las Vegas wastewater using green algae
EDCs are natural hormones and can also be found in many plastics and pharmaceuticals..
Carbon lurking in deep ocean threw ancient climate switch, say researchers: Slowdown of Atlantic circulation sent planet into deep freeze
A new study of sediments from the Atlantic bottom directly links this slowdown with a massive buildup of carbon dragged from the air into the abyss.
Laying the ground for robotic strategies in environmental protection
With this motivation, a team of roboticists at Harvard's Wyss Institute for Biologically Inspired Engineering has developed a robot that can autonomously drive interlocking steel sheet piles into soil.
The structures that it builds could function as retaining walls or check dams for erosion control.
The study will be presented
Cross-boundary solutions for wicked weeds
The issue is weeds aren't just a problem for the landowner where they grow, Bagavathiannan said..
