Woody vegetation, such as trees and shrubs, has increased dramatically in Ozark grasslands over the past 75 years, according to a study published this week in the journal Landscape Ecology. If these ecosystems continue to favor woody vegetation, will it be possible to maintain open grasslands for the foreseeable future?
Human activities could change the pace of evolution, similar to what occurred 66 million years ago when a giant asteroid wiped out the dinosaurs, leaving modern birds as their only descendants. That's one conclusion drawn by the authors of a new study published in Systematic Biology.
An MIT team has determined formulas to guide development of a promising new high-tech material, composed of insulating metal oxides known as alkaline-earth-metal binary oxides, that could lead to better computer memory chips, refrigeration systems, and other devices.
A new paper in the journal Astrobiology suggests NASA and others hunting for proof of Martian biology in the form of 'microfossils' could use the element vanadium in combination with Raman spectroscopy to confirm traces of extraterrestrial life.
Tropical Storm Jose continued to spin south of Massachusetts when NASA's Aqua satellite flew overhead from space and captured an image of the large storm that hasn't moved much.
Exceptionally preserved trilobite fossils from China, dating back to more than 500 million years ago, have revealed new insights into the extinct marine animal's digestive system. The new study shows that at least two trilobite species evolved a stomach structure 20 million years earlier than previously thought.
New research is set to change the textbook understanding of how plants breathe.
Researchers have quantified the astonishingly high speeds at which future solar cells would have to operate in order to stretch what are presently seen as natural limits on their energy conversion efficiency.
How did Neanderthals grow? Does modern man develop in the same way as Homo neanderthalensis did? How does the size of the brain affect the development of the body? A study led by the Spanish National Research Council researcher, Antonio Rosas, has studied the fossil remains of a Neanderthal child's skeleton in order to establish whether there are differences between the growth of Neanderthals and that of sapiens.
A partnership between QUT, the NSW Government and farmers could lead to the eventual eradication of the highly invasive African lovegrass threatening pastures and native grasslands Australia-wide. What they discovered is that local knowledge is the key to a successful management approach.
