The top predators of the Southern Ocean, far-ranging seabirds, are tied both to the health of the ocean ecosystem and to global climate regulation through a mutual relationship with phytoplankton, according to newly published work from the University of California, Davis.
According to a study carried out by two master’s students at Linköping University, large amounts of carbon dioxide equivalents taken up by plants on land are returned to the atmosphere from aquatic environments.
Researchers from North Carolina State University have developed a new, stretchable antenna that can be incorporated into wearable technologies, such as health monitoring devices.
From super-lubricants, to solar cells, to the fledgling technology of valleytronics, there is much to be excited about with the discovery of a unique new two-dimensional semiconductor, rhenium disulfide, by researchers at Berkeley Lab’s Molecular Foundry. Rhenium disulfide, unlike molybdenum disulfide and other dichalcogenides, behaves electronically as if it were a 2D monolayer even as a 3D bulk material.
he value of forests and tree-based ecosystems extends far beyond carbon sequestration; they are the foundation of sustainable societies.
Far beneath the surface of the ocean, deep currents act as conveyer belts, channeling heat, carbon, oxygen and nutrients around the globe.
Scientists at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have discovered a potential way to make graphene – a single layer of carbon atoms with great promise for future electronics – superconducting, a state in which it would carry electricity with 100 percent efficiency.
Algae are organisms useful in many ways in the transition towards a bio-economy. Even in a cool climate as in Finland, algae might be used to produce biochemicals and biofuels, besides use in capture of industrial carbon dioxide emissions. The ALGIDA project coordinated by VTT Technical Research Centre of Finland explored algae growing in Finland.
252 million years ago the largest extinction event occurred at the end of the Permian age. It wiped out almost 90 percent of all life in water. So far researchers had assumed that the ecosystems gradually recovered from this catastrophe over a long stretch of eight to nine million years and that large predators at the uppermost end of the food chain were the last to reappear.
Connecting extreme weather to climate change distracts from the need to protect society from high-impact weather events which will continue to happen irrespective of human-induced climate change, say experts.
The worldwide demand for solar and wind power continues to skyrocket. Since 2009, global solar photovoltaic installations have increased about 40 percent a year on average, and the installed capacity of wind turbines has doubled.
If you think your origami skills can’t be beat – try this: (1) use the world’s thinnest material, (2) make the origami fold and unfold itself, and (3) pack into your miniscule origami box enough hydrogen atoms to exceed future U.S. goals for hydrogen energy storage devices. Researchers from the University of Maryland have done all three.
The first room-temperature light detector that can sense the full infrared spectrum has the potential to put heat vision technology into a contact lens. Unlike comparable mid- and far-infrared detectors currently on the market, the detector developed by University of Michigan engineering researchers doesn't need bulky cooling equipment to work.
Your brain's ability to instantly link what you see with what you do is down to a dedicated information 'highway', suggests new UCL-led research.
Radiological damage to microbes near the site of the Chernobyl disaster has slowed the decomposition of fallen leaves and other plant matter in the area, according to a study just published in the journal Oecologia. The resulting buildup of dry, loose detritus is a wildfire hazard that poses the threat of spreading radioactivity from the Chernobyl area.
Carbon nanotubes are becoming increasingly attractive for photovoltaic solar cells as a replacement to silicon. Researchers at Umeå University in Sweden have discovered that controlled placement of the carbon nanotubes into nano-structures produces a huge boost in electronic performance. Their groundbreaking results are published in the prestigious journal Advanced Materials.
Lewis Owen has been scraping out icy fragments of history's truth from one of the most glaciated regions on Earth for the past 25 years. His frequent excursions to Tibet and the Himalayas have led the University of Cincinnati professor of geology to some cold, hard facts.
A team of University of Toronto physicists led by Alex Hayat has proposed a novel and efficient way to leverage the strange quantum physics phenomenon known as entanglement.
Imagine powering your cell phone by simply walking around your office or rubbing it with the palm of your hand. Rather than plugging it into the wall, you become the power source. Researchers at the 247th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society, presented these commercial possibilities and a unique vision for green energy.
Plants have many valuable functions: They provide food and fuel, release the oxygen that we breathe, and add beauty to our surroundings. Now, a team of MIT researchers wants to make plants even more useful by augmenting them with nanomaterials that could enhance their energy production and give them completely new functions, such as monitoring environmental pollutants.
