New study shows how existing cropland could feed billions more
Feeding a growing human population without increasing stresses on Earth's strained land and water resources may seem like an impossible challenge. But according to a new report by researchers at the University ...
Escherichia coli bacteria produce diesel on demand
It sounds like science fiction but a team from the University of Exeter, with support from Shell, has developed a method to make bacteria produce diesel on demand. While the technology still faces many significant ...
Study casts doubt on climate benefit of biofuels from corn residue
Using corn crop residue to make ethanol and other biofuels reduces soil carbon and can generate more greenhouse gases than gasoline, according to a study published today in the journal Nature Climate Change.
New catalyst for safe, reversible hydrogen storage
(PhysOrg.com) -- Scientists at the Brookhaven National Laboratory and collaborators have developed a new catalyst that reversibly converts hydrogen gas and carbon dioxide to a liquid under very mild conditions. ...
Microbiologists reveal unexpected properties of methane-producing microbe
For 40 years, scientists thought they understood how certain bacteria work together to anaerobically digest biomass to produce methane gas, important in bioenergy and the major source of greenhouse gas. But ...

Graphene: New electronics material closer to commercial reality
(PhysOrg.com) -- Researchers have developed a method for creating single-crystal arrays of a material called graphene, an advance that opens up the possibility of a replacement for silicon in high-performance ...
Researchers discover less expensive low-temperature catalyst for hydrogen purification
(PhysOrg.com) -- Engineering researchers from Tufts University, the University of Wisconsin-Madison and Harvard University have demonstrated the low-temperature efficacy of an atomically dispersed platinum catalyst, which ...
Two strains of bacteria team up, thrive on limited resources
In a discovery that further demonstrates just how unexpected and unusual nature can be, scientists have found two strains of bacteria whose symbiotic relationship is unlike anything seen before.
Meeting climate targets may require reducing meat and dairy consumption
Greenhouse gas emissions from food production may threaten the UN climate target of limiting global warming to 2 degrees Celsius, according to research at Chalmers University of Technology, Sweden.
Livestock can produce food that is better for the people and the planet
With one in seven humans undernourished, and with the challenges of population growth and climate change, the need for efficient food production has never been greater. Eight strategies to cut the environmental and economic ...
Better livestock diets to combat climate change and improve food security
Livestock production is responsible for 12% of human-related greenhouse gas emissions, primarily coming from land use change and deforestation caused by expansion of agriculture, as well as methane released ...
Morocco launches solar mega-project at Ouarzazate
Morocco on Friday officially launched the construction of a 160-megawatt solar power plant near the desert city of Ouarzazate, the first in a series of vast solar projects planned in the country.
