Bright yellow fields of oilseed rape are a common sight at this time of year but what lies beneath is a lot more exciting.

Straw from crops such as wheat, barley, oats and oilseed rape is seen as a potential source of biomass for second generation biofuel production. Currently the UK produces around 12 million tons of straw and much of it is used for animal bedding, mushroom compost and energy generation but there still exists a vast surplus.

Tecnalia has collaborated in a study for the European Parliament's Science and Technology Options Assessment Panel (STOA) on the future use of methanol, produced from carbon dioxide, in motorised transport. STOA is the panel that advises MEPs in the sphere of Science and Technology.

The study analysed the barriers –technological, environmental and economic– to producing methanol using carbon dioxide as well as the options that would allow possible uses in automobile transport in the medium and long term.

The costs and benefits were evaluated from the life cycle perspective in order to compare various raw materials for producing methanol and in order to reflect the potential benefits of methanol obtained from CO2.

Wildfires and flooding affect many more people in the USA than earthquakes and landslide and yet the dread, the perceived risk, of the latter two is much greater than for those hazards that are more frequent and cause greater loss of life. Research published in the International Journal of Risk Assessment and Management, suggests that a new paradigm for risk assessment is needed so that mitigation plans in the face of natural disasters can be framed appropriately by policy makers and those in the emergency services.

I am spending the week in the pleasant resort of La Biodola, in the Elba island. Elba is a beautiful island just off the coast of Tuscany. Here Napoleon was exiled after his abdication in 1814 (he arrived here on May 30th). Exactly 200 years later, 100 Italian researchers have decided to exile themselves here to discuss the future 10 years of accelerator-based experiments, to understand where to "put their money", or better their research activities and efforts.

Wind energy is getting a lot of attention and a lot of money - it just isn't generating a lot of electricity yet, no matter what gets claimed in rosy projections. In the real world, they do quite poorly and building more of them doesn't fix it.  Dr. Hui Hu and his group at Iowa State University want to solve a puzzle that has stumped scientists and engineers for hundreds of years; how to make wind work.

Using a large-scale Aerodynamics/Atmospheric Boundary Layer (AABL) Wind Tunnel at Iowa State University, they studied the effects of the relative rotation directions of two tandem wind turbines on the power production performance, the flow characteristics in the turbine wake flows, and the resultant wind loads acting on the turbines.

Children who receive cochlear implants (CI) to help alleviate severe to profound hearing loss are at greater risk of having deficiencies in executive functioning (EF), which are the skills to organize, control and process information in a goal-directed manner.

Permanent hearing loss is a common condition of early childhood, occurring in about 1.5 of every 1,000 births. Cochlear implants help children to achieve spoken language because the devices help them perceive sound. Still, children with cochlear implants can struggle with reading and writing skills and other aspects of cognition.

Blocking a pain receptor in mice not only extends their lifespan, it also gives them a more youthful metabolism, including an improved insulin response that allows them to deal better with high blood sugar.

"We think that blocking this pain receptor and pathway could be very, very useful not only for relieving pain, but for improving lifespan and metabolic health, and in particular for treating diabetes and obesity in humans," said Andrew Dillin, a professor of molecular and cell biology at the University of California, Berkeley, and senior author of a new paper describing these results. "As humans age they report a higher incidence of pain, suggesting that pain might drive the aging process."

Duke University researchers have found an antibody that simultaneously blocks the sensations of pain and itching in studies with mice.

The new antibody works by targeting the voltage-sensitive sodium channels in the cell membrane of neurons. The results appear online on May 22 in Cell.

Voltage-sensitive sodium channels control the flow of sodium ions through the neuron's membrane. These channels open and close by responding to the electric current or action potential of the cells. One particular type of sodium channel, called the Nav1.7 subtype, is responsible for sensing pain.

Scientists from the Magma and Volcanoes Laboratory (CNRS/IRD/Université Blaise Pascal) and the European Synchrotron, the ESRF, have recreated the extreme conditions 600 to 2900 km below the Earth's surface to investigate the melting of basalt in the oceanic tectonic plates. They exposed microscopic pieces of rock to these extreme pressures and temperatures while simultaneously studying their structure with the ESRF's extremely powerful X-ray beam. The results show that basalt produced on the ocean floor has a melting temperature lower than the peridotite which forms the Earth's mantle.

Sorry Australia, you can no longer lay claim to the origins of the iconic New Zealand kiwi - the kiwi's closest relative is not the emu. 

Instead, the diminutive kiwi is most closely related to the extinct Madagascan elephant bird – a 2-3 meter tall, 275 kg giant. And surprisingly, a new study in Science concluded, both of these flightless birds once flew.

A new study by the University of Adelaide's Australian Centre for Ancient DNA (ACAD), has solved a 150-year-old evolutionary mystery about the origins of the giant flightless "ratite" birds, such as the emu and ostrich, which are found across the southern continents. This group contains some of the world's largest birds – such as the extinct giant moa of New Zealand and elephant birds of Madagascar.
