A common mechanism for human and bird sound production
When birds and humans sing it sounds completely different, but now new research reported in the journal Nature Communication shows that the very same physical mechanisms are at play when a bird sings and a human speaks.

Six years of pest fruit fly species investigation compiled in a new special volume
Considered among the pests with the greatest economic impact, the tephritid fruit flies are a serious worldwide problem.

Lettuce quality is improved by modifying its growing conditions
A researcher in the UPV/EHU's department of Plant Biology and Ecology has confirmed that it is possible to improve the nutraceutical quality of the lettuce by modifying its growing conditions but not at the expense of productivity.

New research exploits extraordinary properties of graphene
Innovative new research led by the University of Exeter has demonstrated how the extraordinary properties of graphene can be exploited to create artificial structures that can be used to control and manipulate electromagnetic radiation over a wide range of wavelengths.

Climate migration in focus at official COP21 side event
Lund University will on Dec. 1, together with Hamburg and Lancaster universities and other partners co-organize an official UNFCCC side event to discuss the importance of social science research for understanding climate change-induced migration.

Soil pulled from deep under Oregon's unglaciated Coast Range unveils frosty past climate
Lush greenery rich in Douglas fir and hemlock trees covers the Triangle Lake valley of the Oregon Coast Range.

Latest major Eastern Pacific hurricane on record headed for landfall in Western Mexico
Hurricane Sandra broke a record in the hurricane history books as the latest major hurricane on record in the Eastern Pacific Ocean.

A horse's eye view: does a pony see what we see?
Horses, humans, and other mammals see the world similarly in spite of differing evolutionary processes, study finds.

What is left of our democratic ambitions?
At a symposium at the University of Montreal, world leading philsophers discuss future of democracy against the backdrop of the Paris terrorism attacks.

Mystery of how snakes lost their legs solved by reptile fossil
Fresh analysis of a reptile fossil is helping scientists solve an evolutionary puzzle -- how snakes lost their limbs.

Can the oxygen in the blood be measured if the nails have been painted?
When a patient is admitted to A&E, one of the first clinical actions is to measure the concentration of oxygen in the blood by using a pulse oximeter positioned along the length of the nail.

Extreme heatwaves may hit Europe in the short term
Regional climate projections for the two coming decades (2021-2040) suggest enhanced probability of heatwaves anywhere in Europe, which would be comparable or greater than the Russian heatwave in 2010 -- the worst since 1950 -- according to a JRC-led article published today in Environmental Research Letters.

The switch molecule
A single organic molecule with a molybdenum atom as its center, can be switched back and forth between two different quantum states with very different electrical conduction.

Even the elderly can recover from a severe traumatic brain injury
According to a study completed at the University of Helsinki and Helsinki University Hospital, Finland, even patients over the age of 75 may recover from severe traumatic brain injury.

Cage the fly: Walk-in field cages to assess mating compatibility in pest fruit flies
Fruit flies studies on mating compatibility have been examined to assess the usefulness of walk-in field cages in sexual behavior research within fruit fly species complexes and recognition of taxonomically misplaced flies.

How finance ministers could fall in love with carbon pricing
Pricing CO2 could help to end the deadlock of international climate policy.

New and presumably tick-borne bacterium discovered in an Austrian fox
Ticks can transmit various diseases to people and animals. Some well-known diseases spread by ticks include tick-borne encephalitis (TBE) and Lyme disease.

Earth's first ecosystems were more complex than previously thought, study finds
Computer simulations have allowed scientists to work out how a puzzling 555-million-year-old organism with no known modern relatives fed, revealing that some of the first large, complex organisms on Earth formed ecosystems that were much more complex than previously thought.

Statement: The co-benefits of actions on climate change and public health
On the occasion of the 2015 Paris Climate Conference, the German National Academy of Sciences Leopoldina has published a short statement on the co-benefits of actions on climate change and public health.

Synapse discovery could lead to new treatments for Alzheimer's disease
A team of researchers led by UNSW Australia scientists has discovered how connections between brain cells are destroyed in the early stages of Alzheimer's disease -- work that opens up a new avenue for research on possible treatments for the degenerative brain condition.
