Scars of childhood poverty found in adult brain scans
The chronic stress of childhood poverty can trigger physical changes that have lifelong psychological effects, a study of adult brains has shown. "Some of the anxiety disorders, depression, post traumatic stress disorders, impulsive aggression and substance abuse we're seeing in adults might be traced to a stressful childhood," says Cornell's Gary W. Evans, the Elizabeth Lee Vincent Professor of Human Ecology.

Wytham Woods 'shields local plants'
Wytham Woods 'shields local plants'
A recent study has found that forests with dense canopies, including Oxford's Wytham Woods, can partially shield ground-level plants from the local effects of global warming. As the planet warms, the general trend is for species adapted to survive at higher temperatures to thrive at the expense of those better-suited to colder climates.

Redwood trees reveal history of West Coast rain, fog, ocean conditions
Redwood trees reveal history of West Coast rain, fog, ocean conditions
Many people use tree ring records to see into the past. But redwoods - the iconic trees that are the world's tallest living things - have so far proven too erratic in their growth patterns to help with reconstructing historic climate. A University of Washington researcher has developed a way to use the trees as a window into coastal conditions, using oxygen and carbon atoms in the wood to detect fog and rainfall in previous seasons.

Study of Brazilian Amazon shows 50,000 km of road was built in just three years
Study of Brazilian Amazon shows 50,000 km of road was built in just three years
Nearly 17,000 kilometres of road were built in the Brazilian Amazon rainforest every year between 2004 and 2007. Although road-building is a major contributor to deforestation and habitat loss, the way in which road networks develop is still poorly understood. A new study is among the first to measure the number of roads built in a rainforest ecosystem over an extended period of time.

Reading ancient climate from plankton shells
Climate changes from millions of years ago are recorded at daily rate in ancient sea shells, new research shows. For slow-growing plankton it opens the way to seeing seasonal variations in ocean temperatures Simon Redfern A huge X-ray microscope has revealed growth bands in plankton shells that show how shell chemistry records the sea temperature.

A new collaborative science program is pioneering the development of ultra-sensitive methane-sensing technology. "Given the importance of methane to global climate change, this study is essential," said Manvendra Dubey of Los Alamos National Laboratory. LOS ALAMOS, N.M., Oct. 28, 2013—A new collaborative science program is pioneering the development of ultra-sensitive methane-sensing technology.

Chances are you recognize these names as belonging to invasive species - plants or animals that are relocated from their native habitat to a foreign land, only to prove so prolific that they take over their new home.

National Science Foundation funds study to unlock secrets of biodiversity
The tropics are home to a far greater diversity of life than any other region on the planet, but the reasons for this disparity have puzzled scientists for centuries. Today, the need to clearly understand how biodiversity is created and maintained has intensified in the face of mass extinctions driven by human activity.

Atmosphere of Mars turned to stone
Scientists at the Scottish Universities Environmental Research Centre, the University of Glasgow and the Natural History Museum in London may have discovered how Mars lost its early carbon dioxide-rich atmosphere to become the cold and arid planet we know today. This research provides the first direct evidence from Mars of a process, called 'carbonation' which currently removes carbon dioxide from our own atmosphere, potentially combating climate change on Earth.

Climate change increased the number of deaths
The increased temperatures caused by ongoing climate change in Stockholm, Sweden between 1980 and 2009 caused 300 more premature deaths than if the temperature increase did not take place. In Sweden as a whole, it would mean about 1,500 more premature deaths, according to a study from researchers at Umeň University published Climate Change.

Ecologists uncover ’hyperdominant’ tree species in the Amazon
Academics from the University of Leeds have joined researchers from around the world to generate the first basin-wide estimates of the abundance and distribution of trees in the Amazon rainforest. The research which spans nine countries, belong to only a tiny fraction of the different species found there.

Innovation in renewable-energy technologies is booming
New study shows that research investments and growing markets have fueled a huge rise in new patents. The number of patents issued for renewable-energy technologies has risen sharply over the last decade, according to new research from MIT and the Santa Fe Institute (SFI). The study shows that investments in research and development, as well as in the growth of markets for these products, have helped to spur this dramatic growth in innovation.

U of M researchers suggest complex relationship between phosphorus levels and nitrogen removal in lakes
MINNEAPOLIS / ST. PAUL (10/10/2013) —In the land of 10,000 lakes, one lake has been the starting place for research with implications for big lakes around the world. According to a study published online this week in Science , University of Minnesota researchers, building from studies of nitrogen levels in Lake Superior, uncovered a good news/bad news scenario for lake health that has long-term, global implications for pollution control efforts.

Early bird catches the worm... for dinner
Early bird catches the worm... for dinner
Birds, such as great and blue tits, scout for food in the morning but only return to eat it in late afternoon to maximise their chances of evading predators in the day without starving to death overnight, Oxford University research has found. This 'early bird' strategy was revealed by a team studying the winter foraging behaviour of birds in Wytham Woods, near Oxford.

Climate puzzle over origins of life on Earth
04 Oct 2013 The mystery of why life on Earth evolved when it did has deepened with the publication of a new study today (Friday). Scientists at the CRPG-CNRS University of Lorraine, The University of Manchester and the Institut de Physique du Globe de Paris have ruled out a theory as to why the planet was warm enough to sustain the planet's earliest life forms when the Sun's energy was roughly three-quarters the strength it is today.

The key to a better understanding of the carbon cycle, the flow of contaminants, even the sustainable growth of biofuel crops, starts with the ground beneath your feet. More specifically, it starts with the genomes of the microbes that live in the water and sediment beneath your feet. But that's where things get murky.
