Lithium-air batteries a thing of the future, scientists say

Posted Mon, 14 Feb 2011 17:37:00 GMT by Rachel England

Advances in battery technology such as lithium-air batteries are unlikely to happen soon. Electric vehicles are gaining popularity around the world, but their potential for becoming completely mainstream remains hampered by the limited range of their lithium-ion batteries.

Fly ash treatment proves environmental winner. MSWI reduces the volume and weight of social refuse and generates power as it is burnt. The resulting fly ash contains a variety of sought-after elements, including silica, aluminium, iron, calcium and bromine. However, it also contains elements of lead, zinc, mercury and cadmium (among other heavy metals), making it a hazardous waste material and as such it is predominantly sent to landfill.

The drive towards electric vehicles pick up speed. China is set to create at least 10 million electric car charging points by 2020. A heavy dependence on foreign oil, plus significant CO2 levels are leading the country to push towards a more environmentally friendly transport infrastructure.

The impact of oxygen-poor oceans on the early evolution of animals

How fluctuations in levels of oceanic oxygen affected the early evolution of animal life. The accepted view of the Earth's history is that for its first four billion years it was in an anoxic state and that about 600 million years ago the oceans became oxygen-rich to approximately the degree that they are today.

Hybrid vehicles get bigger and better with significant numbers expected to be on the road by 2015. Hybrid cars like the Toyota Prius have been the automotive success-story of the last decade, and this has fuelled growth in hybrid power for bigger vehicles like buses and trucks. Hybrid vehicles use electric power to supplement the polluting and inefficient internal combustion engine (ICE) which powers most vehicles using petrol or diesel.

US study indicates that Neanderthal extinction was not due to dietry deficiency. Archaeologists cannot agree whether Neanderthals are a separate human species or a subspecies of modern humans.

Six years after the tsunami disaster of 26th December 2004, the set-up of the German-Indonesian Tsunami Early Warning System for the Indian Ocean (GITEWS) has been completed. The Federal Government of Germany contracted the Helmholtz Association, represented by the Helmholtz Centre Potsdam - GFZ German Research Centre for Geosciences, to work on and execute an early warning tsunami system in the Indian Ocean

A team from the NASA Lunar Research Institute concludes that the Earth, Moon and Mars were formed as the result of massive solar impacts. It is known that siderophile, or metal-loving elements such as gold and platinum are common to the mantles of Earth, the Moon and Mars and new research has shown that massive impactors delivered this abundance during the final phase of planet formation

El Sidron in Spain was always a site of mystery thanks to pair of human jawbones discovered there in 1994. They were thought to date back to the Spanish Civil War. In paper released on this week scientists have said that those bones belonged to Neanderthals who died 50,000 years ago.

The launch of Britain's first hydrogen-powered bus service on a major tourist route in the heart of London shows the city is serious about becoming an eco-friendly travel destination. Seeing London as a tourist needn't cost the Earth, in more ways than one.

London botanists are co-ordinating a global hunt for the wild relatives of staple foods, fearing existing crop types may be unable to cope with the threat of climate change. Now, scientists across the world are being asked to search for the wild relatives of a number of staple crops so as to protect global food supplies against the mounting threat of climate change.

Cryptozoology is the study of 'hidden' animals. Those animals that have never previously been recognised by the scientific community and rediscovered animals that were thought to be extinct but show up again, often unexpectedly, in their original habitat.

Scientists at the Harvard Smithsonian centre for Astrophysics say that have isolated arsenic tolerant bacteria from mono lake an ancient alkaline lake in California. They were fed arsenic instead of phosphorous an element essential for life and they gradually replaced the phosphorous with arsenic atoms. This, say scientists, will change the way we view adaptability of life forms.
