Improved agricultural water management could halve the global food gap by 2050 and buffer some of the harmful climate change effects on crop yields. For the first time, scientists investigated systematically the worldwide potential to produce more food with the same amount of water by optimizing rain use and irrigation. They found the potential has previously been underestimated. Investing in crop water management could substantially reduce hunger while at the same time making up for population growth.

University of Exeter research into the impact of climate change will be featured at a prestigious science event in the USA, held this week.
Professor Tim Lenton, Chair in Climate Change and Earth System Science, and Dr Stephan Harrison, Associate Professor of Quaternary Science - both from Exeter's Geography department, will present their world-leading research at the high-profile international event.
WEST LAFAYETTE, Ind. - Global market integration is key to buffering future commodity prices and food security from the negative effects of climate change on agriculture, says a Purdue University agricultural economist.
Rising temperatures and an increase in extreme weather events will likely have adverse impacts on global crop production, leading to higher food prices and food scarcity. But global markets that have the ability to deliver food where it is needed most could help offset these consequences, said Thomas Hertel, distinguished professor of agricultural economics.
The UK's synchrotron science facility, Diamond Light Source, is a hub for renewable energy and energy recycling research, but less well known are its applications as a hub for nuclear research. Work in this area is transforming our energy future by making the nuclear fuel cycle safer, more efficient and more straightforward to use.
Scientists at the world's premier science conference - the American Association for the Advancement of Science (AAAS) annual meeting - will this year be discussing the advances enabled by the UK's pioneering Long-Duration Experiment facility (LDE). Unmatched anywhere in the world, the LDE allows scientists to closely study the atomic and molecular behaviour of matter under different conditions and over a period of two years.
Technological advances are ushering in a new era of understanding in the search for fundamental physical particles - including dark matter - scientists will tell a public event.
Researchers are using analysis of deep space observations together with experiments far underground to hunt for dark matter - an elusive material which, together with dark energy, is thought to account for about 95 per cent of the universe.
RENO - Despite an above average snowpack and several months of wet weather, drought and changing climate conditions continue to plague farmers and ranchers across Nevada and other western states.
For American Indian communities in Northern Nevada, the consequences of a changing ecosystem are severe and will impact generations to come, according to new research and outreach presented today at the American Association for the Advancement of Science (AAAS) Annual Meeting in Washington, D.C.
It's often assumed that exotic metals and minerals critical to clean energy technologies are more price volatile than more common commodity metals. They're mined in much smaller quantities and often as by-products of other high-volume production materials, and even slight changes in production, demand, and consumer end-uses can greatly affect markets.
University of California, Berkeley, scientists are releasing a free Android app that taps a smartphone's ability to record ground shaking from an earthquake, with the goal of creating a worldwide seismic detection network that could eventually warn users of impending jolts from nearby quakes.
Children's singer and songwriter Raffi may have brought beluga whales into popular culture with his 1980 song "Baby Beluga," but surprisingly little is actually known about the life and ecology of these elusive marine mammals that live in some of the world's most remote, frigid waters.
Heterostructures formed by different three-dimensional semiconductors form the foundation for modern electronic and photonic devices. Now, University of Washington scientists have successfully combined two different ultrathin semiconductors -- each just one layer of atoms thick and roughly 100,000 times thinner than a human hair -- to make a new two-dimensional heterostructure with potential uses in clean energy and optically-active electronics. The team, led by Boeing Distinguished Associate Professor Xiaodong Xu, announced its findings in a paper published Feb.
A panel of British and American researchers, speaking at the annual meeting of the American Association for the Advancement of Science (AAAS) in Washington DC, will present updated research revealing how extreme events which affect the food system are increasingly likely to occur, resulting in 'food shocks'.
Food shocks have the potential to wreak havoc on food markets, commodity exports, and families around the world.
One of goals of the Okinawa Institute of Science and Technology Graduate University (OIST) is to foster collaboration between different disciplines. Recently, OIST scientists combined techniques from soft matter physics and structural biology to create and visualise crystals made of surfactants, surface-acting agents that are added in a multitude of products like detergents, cosmetics and paints. Crystals, high ordered arrangement of atoms in 3D, are sought after in both biology and physics, but are often very challenging to produce.
The case was the first announced recording of space-time oscillations -- gravitational waves, reaching the Earth after a catastrophe that happened far in the Universe. That confirms a significant prediction made in the special theory of relativity made by Albert Einstein 1916 and enables a brand-newunprecedented understanding of space.
