Nitrous oxide emissions set to rise in the Pacific Ocean
Nitrous oxide emissions set to rise in the Pacific Ocean
The acidification of the Pacific Ocean in northern Japan is increasing the natural production rate of N2O, an ozone-depleting greenhouse gas. That's the finding of a study carried out jointly by scientists at EPFL, Tokyo Institute of Technology and Japan Agency for Marine-Earth Science and Technology and appearing recently.

"Without Bacteria and Fungi, the Earth Would Look Like Mars"
Our soils filter drinking water and produces food. Soils only carry out these services, because they harbour thousands fungal and bacteria species which work together like the wheels in a clock mechanism. These are the conclusions reached by a study published in the renowned by researchers from Agroscope and the University of Zurich.

Capturing carbon dioxide to make useful products could become big business
Capturing carbon dioxide to make useful products could become big business
Waste carbon dioxide from burning fossil fuels could be used to make valuable products such as plastics, fuels and cement, suggests new research. If done correctly, using waste carbon dioxide (CO2) to make useful products would also help offset the costs of mitigating climate change, argue scientists in a review .

Deep sea vents had ideal conditions for origin of life
By creating protocells in hot, alkaline seawater, a UCL-led research team has added to evidence that the origin of life could have been in deep-sea hydrothermal vents rather than shallow pools. Previous experiments had failed to foster the formation of protocells - seen as a key stepping stone to the development of cell-based life - in such environments, but the new study, published iná Nature Ecology & Evolution , finds that heat and alkalinity might not just be acceptable, but necessary to get life started.

Satellite tracking shows how ships affect clouds and climate
Satellite tracking shows how ships affect clouds and climate
By matching the movement of ships to the changes in clouds caused by their emissions, researchers have shown how strongly the two are connected. When ships burn fossil fuels, they release airborne particles containing various naturally occurring chemicals, including sulphur. These particles are known to modify certain types of clouds, which can affect climate.

Swordfish as oceanographers? Satellite tags allow research of ocean's 'twilight zone' off Florida
Swordfish as oceanographers? Satellite tags allow research of ocean’s ’twilight zone’ off Florida
Researchers from the University of Washington are using high-tech tags to record the movements of swordfish - big, deep-water, migratory, open-ocean fish that are poorly studied - and get a window into the ocean depths they inhabit. The researchers tagged five swordfish in late August off the coast of Miami: Max , Simone , Anthony , Rex and Oliver.

A bird in the nest and moving to Mars: News from the College
Here's a batch of fresh news and announcements from across Imperial. From bird-chick recognition, to Mars explorations, here is some quick-read news from across the College. A bird in the nest Passerine (or ‘perching') birds do not differentiate between the chicks in their nest - meaning they potentially raise chicks that aren't theirs, such as those that are the product of a cheating partner.

Rice yields plummet and arsenic rises in future climate-soil scenarios
Research combining future climate conditions and arsenic-induced soil stresses predicts rice yields could decline about 40 percent by 2100, a loss that would impact about 2 billion people dependent on the global crop. Rice is the largest global staple crop, consumed by more than half the world's population - but new experiments from Stanford University suggest that with climate change, production in major rice-growing regions with endemic soil arsenic will undergo a dramatic decline and jeopardize critical food supplies.

Intact forest loss ’six times worse’ for climate
The impact of losing intact tropical forests is more devastating on the climate than previously thought, according to University of Queensland-led research. The international study has revealed between 2000 and 2013 the clearance of intact tropical forests resulted in a much higher level of carbon being emitted to the atmosphere than first believed - resulting in a 626 per cent increase in the calculated impact on climate.

Climate models and geology reveal new insights into the East Asian monsoon
Climate models and geology reveal new insights into the East Asian monsoon
A team of scientists, led by the University of Bristol, have used climate models and geological records to better understand changes in the East Asian monsoon over long geologic time scales. Their findings, published today in the journal Science Advances , suggest that the monsoon system's development was more sensitive to changes in geography (especially mountain height) rather than carbon dioxide, and that the monsoon came into existence around 40 million years earlier than previously thought.

Insect decline more extensive than suspected
Insect decline more extensive than suspected
Compared to a decade ago, today the number of insect species on many areas has decreased by about one third. This is the result of a survey of an international research team led by scientists from the Technical University of Munich (TUM). The loss of species mainly affects grasslands in the vicinity of intensively farmed land - but also applies to forests and protected areas.

Macaques’ stone tool use varies despite same environment
Stone tool use develops differently within species of Old World monkeys in spite of shared environmental and ecological settings, according to a new study involving UCL. Macaques are the only Old World monkeys that have been observed using percussive stone tools and scientists do not know for certain how or why certain groups have developed this behaviour.

New hydrogen production method could support sustainable fuel creation
A new method of extracting hydrogen from water more efficiently could help underpin the capture of renewable energy in the form of sustainable fuel, scientists say. In a new paper, published today , researchers from universities in the UK, Portugal, Germany and Hungary describe how pulsing electric current through a layered catalyst has allowed them to almost double the amount of hydrogen produced per millivolt of electricity used during the process.

’DNA time capsule’ reveals birthplace of modern humans
A landmark study led by Sydney researchers pinpoints the birthplace of modern humans in southern Africa and suggests how climate change may have driven the first migrations. A Sydney-led study has found that the earliest ancestors of anatomically modern humans ( Homo sapiens sapiens ) emerged in a southern African 'homeland' and thrived there for 70 thousand years.

Abrupt shifts in Arctic climate projected
Channels McGill University News and Events Researchers from McGill University project that as the permafrost continues to degrade, the climate in various regions of the Arctic could potentially change abruptly, in the relatively near future. Their research, which was published today in Nature Climate Change , also suggests that as the permafrost degrades, the severity of wildfires will double from one year to the next and remain at the new and higher rate for regions in the Northwestern Territories and the Yukon.

Antarctic sea ice is key to triggering ice ages
We've known for years that Earth's climate is like a giant Rube Goldberg machine: Pull one lever, and a massive chain of events starts into motion. Yet many of the steps that drive these changes have remained shrouded in uncertainty. "One key question in the field is still what caused the Earth to periodically cycle in and out of ice ages," said Asst.
