Delft breakthrough in bioethanol production from agricultural waste
With the introduction of a single bacterial gene into yeast, researchers from Delft University of Technology in the Netherlands achieved three improvements in bioethanol production from agricultural waste material: 'More ethanol, less acetate and elimination of the major by-product glycerol' This week the invention was published in the scientific... view more...

Flax and yellow flowers can produce bioethanol
Surplus biomass from the production of flax shives, and generated from Brassica carinata, a yellow-flowered plant related to those which engulf fields in spring, can be used to produce bioethanol.   view more (2009-11-23)

Scientists unlock clues for tailoring corn plant for food, energy needs
Scientists have long known that the offspring of two inbred strains tend to be superior to both their parents. Now, a team of researchers including a University of Florida geneticist has discovered clues to why that might be the case for one of the most important crops in the world: corn.   view more (2009-11-20)

'Hobbits' are a new human species -- according to the statistical analysis of fossils
Researchers from Stony Brook University Medical Center in New York have confirmed that Homo floresiensis is a genuine ancient human species and not a descendant of healthy humans dwarfed by disease.   view more (2009-11-19)

Oceans' uptake of manmade carbon may be slowing
The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air.   view more (2009-11-19)

Developing 'green' tires that boost mileage and cut carbon dioxide emissions
A new generation of "green" automobile tires that can boost fuel efficiency without sacrificing safety and durability is rolling their way through the research pipeline.   view more (2009-11-19)

UT Knoxville and ORNL researchers turn algae into high-temperature hydrogen source
In the quest to make hydrogen as a clean alternative fuel source, researchers have been stymied about how to create usable hydrogen that is clean and sustainable without relying on an intensive, high-energy process that outweighs the benefits of not using petroleum to power vehicles.   view more (2009-11-12)

Climate studies to benefit from 12 years of satellite aerosol data
Aerosols, very small particles suspended in the air, play an important role in the global climate balance and in regulating climate change.   view more (2009-11-11)

Warm-blooded dinosaurs worked up a sweat
Were dinosaurs "warm-blooded" like present-day mammals and birds, or "cold-blooded" like present day lizards? The implications of this simple-sounding question go beyond deciding whether or not you'd snuggle up to a dinosaur on a cold winter's evening.   view more (2009-11-11)

New fossil plant discovery links Patagonia to New Guinea in a warmer past
Fossil plants are windows to the past, providing us with clues as to what our planet looked like millions of years ago.   view more (2009-11-11)

The last European hadrosaurs lived in the Iberian Peninsula
Spanish researchers have studied the fossil record of hadrosaurs, the so-called 'duck-billed' dinosaurs, in the Iberian Peninsula for the purpose of determining that they were the last of their kind to inhabit the European continent before disappearing during the K/T extinction event that occurred 65.5 million years ago.   view more (2009-11-06)

Boat tail reduces truck fuel consumption by 7.5 percent
An articulated lorry was driven for a period of one year with a boat tail (of varying length) and one year without a boat tail. The improved aerodynamics, depending on the length of the boat tail, resulted in reduced fuel consumption (and emissions!) of up to 7.5 percent. The optimum boat tail length proved to be two metres.   view more (2009-11-06)

Chemists describe solar energy progress and challenges, including the 'artificial leaf'
Scientists are making progress toward development of an "artificial leaf" that mimics a real leaf's chemical magic with photosynthesis - but instead converts sunlight and water into a liquid fuel such as methanol for cars and trucks.   view more (2009-11-06)

Toward home-brewed electricity with 'personalized solar energy'
New scientific discoveries are moving society toward the era of "personalized solar energy," in which the focus of electricity production shifts from huge central generating stations to individuals in their own homes and communities.   view more (2009-11-05)

The humble beginnings of a king
Tyrannosaurus rex and related large carnivorous dinosaurs together form the family Tyrannosauridae. A long forgotten fossil skull in the collections of the Natural History Museum in London has now provided crucial clues to the early stages of the lengthy evolutionary history of these fearsome predators.   view more (2009-11-05)

New dinosaur species from Montana
A husband and wife team of American paleontologists has discovered a new species of dinosaur that lived 112 million years ago during the early Cretaceous of central Montana.   view more (2009-11-02)

The largest bat in Europe inhabited northeastern Spain more than 10,000 years ago
Spanish researchers have confirmed that the largest bat in Europe, Nyctalus lasiopterus, was present in north-eastern Spain during the Late Pleistocene (between 120,000 and 10,000 years ago).   view more (2009-10-30)

Snail fossils suggest semiarid eastern Canary Islands were wetter 50,000 years ago
Fossil land snail shells found in ancient soils on the subtropical eastern Canary Islands show that the Spanish archipelago off the northwest coast of Africa has become progressively drier over the past 50,000 years.   view more (2009-10-28)

Galaxy cluster smashes distance record
The most distant galaxy cluster yet has been discovered by combining data from NASA's Chandra X-ray Observatory and optical and infrared telescopes.   view more (2009-10-23)

Ethiopia 27 million years ago had higher rainfall, warmer soil
Thirty million years ago, before Ethiopia's mountainous highlands split and the Great Rift Valley formed, the tropical zone had warmer soil temperatures, higher rainfall and different atmospheric circulation patterns than it does today, according to new research of fossil soils found in the central African nation.   view more (2009-10-23)
