Study shows wheat crop yield can be increased by up to 20% using new chemical technology
December 15, 2016 09:38 AM - University of Oxford

UK scientists have created a synthetic molecule that, when applied to crops, has been shown to increase the size and starch content of wheat grains in the lab by up to 20%.

The new plant application, developed by Rothamsted Research and Oxford University, could help solve the issue of increasing food insecurity across the globe. Some 795 million people are undernourished, and this year's El Nino has shown how vulnerable many countries are to climate-induced drought.

How noise pollution impacts marine ecology
December 13, 2016 07:14 AM - Laura Briggs, The Ecologist

Marine ecologists have shown how noise pollution is changing the behaviour of marine animals - and how its elimination will significantly help build their resilience. Laura Briggs reports.

Building up a library of sound from marine creatures including cod, whelks and sea slugs is important to helping build resilience in species affected by noise pollution, according to Exeter University's Associate Professor in Marine Biology and Global Change Dr Steve Simpson.

Human noise factors including busy shipping lanes, wind farms and water tourism can all impact on the calls of various species - including cod which relies on sound for finding a mate with their "song".

Wind turbines may have beneficial effects for crops
December 9, 2016 05:15 PM - Iowa State University

A multi-year study led by an Iowa State University scientist suggests the turbines commonly used in the state to capture wind energy may have a positive effect on crops.

Gene Takle, a Distinguished Professor of agronomy and geological and atmospheric sciences, said tall wind turbines disbursed throughout a field create air turbulence that may help plants by affecting variables such as temperature and carbon dioxide concentrations.

Tongass Forest Plan Amendment supports sustainable communities and viable economies - Amended plan focuses on transition to young growth harvest and renewable energy development
December 9, 2016 12:26 PM - USDA Forest Service

KETCHIKAN, Alaska, December 9, 2016 – M. Earl Stewart, the Forest Supervisor for the Tongass National Forest, Alaska Region, has signed the final Record of Decision (ROD) for the amended Tongass National Forest Land and Resource Management Plan (Tongass Forest Plan). The Final ROD documents the Forest Supervisor’s rationale for approving the Tongass Forest Plan Amendment. The Tongass Forest Plan Amendment will become effective in 30 days.

Against the Tide: A Fish Adapts Quickly to Lethal Levels of Pollution
December 9, 2016 07:24 AM - Kat Kerlin, UC Davis

Evolution is working hard to rescue some urban fish from a lethal, human-altered environment, according to a study led by the University of California, Davis, and published Dec. 9 in the journal Science. 

While environmental change is outpacing the rate of evolution for many other species, Atlantic killifish living in four polluted East Coast estuaries turn out to be remarkably resilient. These fish have adapted to levels of highly toxic industrial pollutants that would normally kill them.

The Paris Climate Deal Is Now in Force. What Comes Next?
December 4, 2016 09:07 PM - Steve Williams, Care2

The Paris Agreement was hailed as a turning point for world governments tackling climate change, and it has now come into effect. What does this mean for the world — and where do we go from here?

On Friday, November 4, the Paris Agreement went into effect, meaning that the agreement made last year by nearly 200 international delegates must now be honored. To recognize the consensus coming into force, the United Nations stated that it is a moment to celebrate – and to take concerted action.

“We remain in a race against time,” UN Secretary General Ban Ki-moon emphasized. ”Now is the time to strengthen global resolve, do what science demands and seize the opportunity to build a safer, more sustainable world for all.”

CharIoT on course to deliver healthier homes and lower energy bills
December 2, 2016 11:46 AM - Engineering and Physical Sciences Research Council

Successful trials of CharIoT, a unique new system that simultaneously records temperature, humidity and energy use in the home, have opened the way for low-income households to save money while reducing risks to their health.

Harnessing Internet of Things technology, the system generates easy-to-use data that can help local authorities, housing associations, energy suppliers, health authorities and others to target and tailor the energy advice they give to vulnerable people.

As well as revealing under- or over-heated parts of a home, CharIoT enables energy advisors to pinpoint where and why damp or mould may pose a problem. They can then suggest, for example, ways of using heaters more efficiently and cost-effectively, blocking draughts and eliminating dampness through better ventilation.

How Solar power is bringing food security to Africa
November 25, 2016 11:54 AM - Joe Ware , The Ecologist

Malawi is one of the poorest countries in the world. Ninety per cent of Malawians live in rural areas; agriculture makes up 80 per cent of the labour force and 80 per cent of its exports. With so many people reliant on growing things from the ground, disruptions to the climate threatens the wellbeing of an entire nation.

For centuries Malawian farmers have learned the patterns of the seasons - when to plant their seeds in order to capture the rains that watered the ground and brought forth food to eat and sell. But this life-saving knowledge is becoming worthless, as rainfall patterns are distorted by a changing climate and the El Nino weather event, which this year created the worst food crisis in 25 years.

Concrete jungle functions as carbon sink
November 22, 2016 07:03 AM - UCI News

Cement manufacturing is among the most carbon-intensive industrial processes, but an international team of researchers has found that over time, the widely used building material reabsorbs much of the CO2 emitted when it was made.
