Boosts in productivity of corn and other crops modify Northern Hemisphere carbon dioxide cycle

Each year in the Northern Hemisphere, levels of atmospheric carbon dioxide drop in the summer as plants "inhale," then climb again as they exhale after the growing season.

Mediterranean meteorological tide has increased by over a millimetre a year since 1989

This is Les Rotes beach in Denia (Alicante, Spain).A new database developed by the University of Cantabria (Spain) provides data on sea level variation due to atmospheric changes in the south of Europe between 1948 and 2009. Over...

NASA computer model provides a new portrait of carbon dioxide

An ultra-high-resolution NASA computer model has given scientists a stunning new look at how carbon dioxide in the atmosphere travels around the globe.

Using science to open way to 'blue economy'

Today, scientists at the Natural Capital Project share new science and open source software that can calculate risk to coastal and marine ecosystems. These novel tools, described in the journal...

Researchers calculate 'hidden' emissions in traded meat

An international team of researchers has, for the first time, estimated the amount of methane (CH4) and nitrous oxide (N2O) that countries release into the atmosphere when producing meat from...

Ocean primed for more El Niño: ANU media release

In this image, Dr Jess Carilli samples a <i>Porites</i> coral in Kiribati.The ocean is warming steadily and setting up the conditions for stronger El Niño weather events, a new study has shown.

Life in Earth's primordial sea was starved for sulfate

This is a research vessel on Lake Matano, Indonesia -- a modern lake with chemistry similar to Earth's early oceans.Earth's ancient oceans held much lower concentrations of sulfate -- a key biological nutrient -- than previously recognized, according to research published this week in Science.

New laws threaten Brazil's unique ecosystems

Brazil's globally significant ecosystems could be exposed to mining and dams if proposals currently being debated by the Brazilian Congress go ahead, according to researchers publishing in the journal <i>Science</i> this week.Brazil´s globally significant ecosystems could be exposed to mining and dams if proposals currently being debated by the Brazilian Congress go ahead, according to researchers publishing in the journal Science...

Synthetic biology for space exploration

Synthetic biology could be a key to manned space exploration of Mars.Does synthetic biology hold the key to manned space exploration of the Moon and Mars? Berkeley Lab researchers have used synthetic biology to produce an inexpensive and reliable microbial-based alternative...

Small New Zealand population initiated rapid forest transition c. 750 years ago

Human-set fires by a small Polynesian population in New Zealand ~750 years ago may have caused fire-vulnerable forests to shift to shrub land over decades, rather than over centuries, as...

Study shows tectonic plates not rigid, deform horizontally in cooling process

Corn&#233; Kreemer, associate professor in the College of Science at the University of Nevada, Reno, conducts research on plate tectonics and geodetics. His latest research shows that oceanic tectonic plates deform due to cooling, causing shortening of the plates and mid-plate seismicity.The puzzle pieces of tectonic plates that make up the outer layer of earth are not rigid and don't fit together as nicely as we were taught in high school.

Livermore scientists show salinity counts when it comes to sea level

Using ocean observations and a large suite of climate models, Lawrence Livermore National Laboratory scientists have found that long-term salinity changes have a stronger influence on regional sea level changes than previously thought.

Study: Environmental bleaching impairs long-term coral reproduction

This is a photo of bleached coral near the Panamanian coast.A new study by a Florida State University biologist shows that bleaching events brought on by rising sea temperatures are having a detrimental long-term impact on coral.

Salamanders are a more abundant food source in forest ecosystems than previously thought

Semlitsch's study measured the population density and biomass of the Southern Redback Salamander in the Ozark Highlands in Missouri.In the 1970s, ecologists published results from one of the first whole-forest ecosystem studies ever conducted in Hubbard Brook, New Hampshire. In the paper, scientists reported that salamanders represent one...

Overhaul in tropical forest research needed

This image from the Carnegie Airborne Observatory shows the large variation in tree canopy height across multiple landscapes in southeastern Peru. The tallest trees are in dark red, with green and blue colors representing shorter trees and forest canopy gaps. Single field plots are used to represent these landscapes, often resulting in substantial biases.New work from a team led by Carnegie's Greg Asner shows the limitations of long-used research methods in tropical rainforest ecology and points to new technological approaches for understanding forest...

Lightning expected to increase by 50 percent with global warming

This graphic shows the intensity of lightning flashes averaged over the year in the lower 48 states during 2011.Today's climate models predict a 50 percent increase in lightning strikes across the United States during this century as a result of warming temperatures associated with climate change.

A sea change for marine conservation

This image depicts fishers in Kenya.Harnessing 'people power' to manage fisheries in the developing world has significantly benefited local communities and coral reefs, according to new research.

Cockroach cyborgs use microphones to detect, trace sounds

North Carolina State University researchers have developed technology that allows cyborg cockroaches, or biobots, to pick up sounds with small microphones and seek out the source of the sound.North Carolina State University researchers have developed technology that allows cyborg cockroaches, or biobots, to pick up sounds with small microphones and seek out the source of the sound. The...

Rare 2.5-billion-year-old rocks reveal hot spot of sulfur-breathing bacteria

Gold miners prospecting in a mountainous region of Brazil drilled this 590-foot cylinder of bedrock from the Neoarchaean Eon, which provides rare evidence of conditions on Earth 2.5 billion years ago.Wriggle your toes in a marsh's mucky bottom sediment and you'll probably inhale a rotten egg smell, the distinctive odor of hydrogen sulfide gas. That's the biochemical signature of sulfur-using...

Offshore islands amplify, rather than dissipate, a tsunami's power

This model shows the impact of coastal islands on a tsunami's height.A long-held belief that offshore islands protect the mainland from tsunamis turns out to be the exact opposite of the truth, according to a new study.

How corals can actually benefit from climate change effects

Justin Ries, an associate professor at the Marine Science Center, researches biogeochemical oceanic change over long time periods.Researchers from North­eastern University's Marine Sci­ence Center and the Uni­ver­sity of North Car­olina at Chapel Hill have found that mod­erate ocean acid­i­fi­ca­tion and warming can actu­ally enhance the growth rate...

Berkeley Lab scientists ID new driver behind Arctic warming

Scientists have identified a mechanism that could turn out to be a big contributor to warming in the Arctic region and melting sea ice.
