The figures come out in a study made at Aalto University in Finland examining developments in food availability and food self-sufficiency in 1965. Researchers of Aalto University examined the development of food availability in recent decades for the first time.
Food availability has improved especially in the Middle East and North Africa, Latin America, China, and Southeast Asia. Although food availability has increased on the global level, food self-sufficiency has remained relatively low.
Electronic devices such as mobile phones and tablets spur on a scientific race to find smaller and smaller information processing and storage elements. One of the challenges in this race is to reproduce certain magnetic effects at nanometre scale.
This work was recently published in Physical Review Letters.
Specific types of fish farming can be accomplished with minimal or no harm to the coastal ocean environment as long as proper planning and safeguards are in place, according to a new report from researchers at NOAA's National Ocean Service.
The study, led by scientists at National Ocean Service's National Centers for Coastal Ocean Science (NCCOS), evaluated the environmental effects of finfish aquaculture, including interactions with water quality, benthic habitats, and marine life across various farming practices and habitat types.
It is increasingly recognized that climate change has the potential to threaten people and nature, and that it is imperative to tackle the drivers of climate change, namely greenhouse gases. One way to slow climate change is to increase the number of trees on Earth, as they, through photosynthesis, take up the greenhouse gas carbon dioxide, converting it to carbon products which are stored in the vegetation (in the form of wood, roots, leaves) and oxygen.

Can OAE2 help us understand current global warming? Did trilobites venture into upper intertidal zones? When did vast landmasses first emerge above sea level?

(Ulsan, South Korea 18 Dec. 2013): Ulsan National Institute of Science and Technology (UNIST) announced a method for the mass production of boron/nitrogen co-doped graphene nanoplatelets, which led to the fabrication of a graphene-based field -effect transistor (FET) with semiconducting nature. This opens up opportunities for practical use in electronic devices.
Leipzig, Germany. Pollen reflects more sunlight than previously known, and makes up to one third of the total amount of aerosol particles in the atmosphere. Aerosol particles influence optical depth which provides a measure of the opacity of the atmosphere. These results, reported by scientists of the Gwangju Institute of Science and Technology (GIST) in Korea and the Leibniz-Institute of Tropospheric Research (TROPOS), are published in the research journal Atmospheric Environment.
CHAMPAIGN, Ill. — Halomonas are a hardy breed of bacteria. They can withstand heat, high salinity, low oxygen, utter darkness and pressures that would kill most other organisms. These traits enable these microbes to eke out a living in deep sandstone formations that also happen to be useful for hydrocarbon extraction and carbon sequestration, researchers report in a new study.
WASHINGTON - Bureau of Reclamation Commissioner Michael L. Connor released the Lower Rio Grande Basin Study that evaluated the impacts of climate change on water demand and supply imbalances along the Rio Grande along the United States/Mexico border from Fort Quitman, Tex., to the Gulf of Mexico.
Hacking the Earth's climate to counteract global warming – a subject that elicits strong reactions from both sides – is the topic of a December special issue of the journal Climatic Change. A dozen research papers include the most detailed description yet of the proposed Oxford Principles to govern geoengineering research, as well as surveys on the technical hurdles, ethics and regulatory issues related to deliberately manipulating the planet's climate.
Phenylalanine pairs capable of forming a molecular switch are also present in many other signaling proteins, including receptors in human cells, making it an attractive target for drug design and biotechnology applications.
However, using Anton, researchers were able to simulate only a small part of the chemoreceptor containing the Phe396 pair known as a dimer, meaning two identical molecules. But these two molecules do not work alone.
Emperor penguins maintain the tight huddle that protects them from the harsh conditions of an Antarctic winter with stop-and-go movements like cars in a traffic jam, a new study has shown.
By using a mathematical model that recreated the positions, movements and interactions of individual penguins in a huddle, researchers have revealed that an individual penguin only needs to move 2 cm in any direction for its neighbour to react and also perform a step to stay close to it.
Six in ten 13-year-old girls, compared to four in 10 boys the same age, are afraid of gaining weight or getting fat according to new research on eating disorders from the UCL Institute of Child Health (UK) in collaboration with the London School of Hygiene and Tropical Medicine (UK).
Latest climate and biosphere modelling suggests that the length of time carbon remains in vegetation during the global carbon cycle - known as 'residence time' - is the key "uncertainty" in predicting how Earth's terrestrial plant life - and consequently almost all life - will respond to higher CO2 levels and global warming, say researchers.
