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".

Sandia National Laboratories has signed a Cooperative Research and Development Agreement (CRADA) with the government of Singapore’s Energy Market Authority (EMA) that will tap into the labs’ expertise in energy storage.

EMA is the statutory body in Singapore responsible for ensuring a reliable and secure energy supply, promoting competition in the energy market and developing a dynamic energy sector. Last year, EMA invited Sandia to organize a workshop on the latest developments in storage technologies. The two-day event in the Southeast Asian island city-state led to a CRADA under which Sandia will help set up Singapore’s first grid energy storage test-bed.

“Sandia will collaboratively develop an energy storage test-bed to better understand the feasibility of deploying energy storage systems [ESS] in Singapore,” said Dan Borneo, Sandia team lead on the project.

With a new technique for manufacturing single-layer organic polymer solar cells, scientists at UC Santa Barbara and three other universities might very well move organic photovoltaics into a whole new generation of wearable devices and enable small-scale distributed power generation.

The simple doping solution-based process involves briefly immersing organic semiconductor films in a solution at room temperature. This technique, which could replace a more complex approach that requires vacuum processing, has the potential to affect many device platforms, including organic printed electronics, sensors, photodetectors and light-emitting diodes. The researchers’ findings appear in the journal Nature Materials.

Steel production generates some hundred million tons of steel slag worldwide each year. This giant mountain of leftovers is largely dumped. TU/e professor of building materials, Jos Brouwers, will be working with industrial partners to investigate whether he can make cement out of it. If he succeeds, more CO2 emissions can be cut than is produced yearly by all the traffic in the Netherlands.

Steel slag is produced by the conversion of raw iron into steel – around 125 million tons of it per year. Much of that is dumped and only a small portion used, in embankments. That’s a shame, professor Jos Brouwers says, because the mineralogical composition very closely resembles that of cement. It contains the same components, but in different ratios. And it is public knowledge that the cement industry emits a very high amount of CO2: five percent of the global total. A cement substitute with no extra CO2 emissions would, therefore, be most welcome.

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.

A new study predicts that warming temperatures will contribute to the release into the atmosphere of carbon that has long been locked up securely in the coldest reaches of our planet.

Soil and climate expert Katherine Todd-Brown, a scientist at the Department of Energy's Pacific Northwest National Laboratory, is an author of the paper, published in the Dec. 1 issue of the journal Nature, which draws upon data collected through 49 separate field experiments around the world.

The research was led by Thomas Crowther, formerly of Yale and now at the Netherlands Institute of Ecology, and colleague Mark Bradford at Yale. Scientists from more than 30 institutions across the globe, including PNNL, collaborated on the study.

Researchers at the University of Tokyo and their collaborators have revealed a relationship between helium levels in groundwater and the amount of stress exerted on inner rock layers of the earth, found at locations near the epicenter of the 2016 Kumamoto earthquake. Scientists hope the finding will lead to the development of a monitoring system that catches stress changes that could foreshadow a big earthquake.

Several studies, including some on the massive earthquake in Kobe, Japan, in 1995, have indicated that changes to the chemical makeup of groundwater may occur prior to earthquakes. However, researchers still needed to accumulate evidence to link the occurrence of earthquakes to such chemical changes before establishing a strong correlation between the two.

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.

A nanosize squeeze can significantly boost the performance of platinum catalysts that help generate energy in fuel cells, according to a new study by Stanford scientists.

The team bonded a platinum catalyst to a thin material that expands and contracts as electrons move in and out, and found that squeezing the platinum a fraction of a nanometer nearly doubled its catalytic activity. The findings are published in the Nov. 25 issue of the journal Science.

Climate change is one of the most serious threats facing the world today. With the effectuation of the Paris Agreement, there has been a rising interest on carbon capture and utilization (CCU).

A new study, led by Professor Jae Sung Lee of Energy and Chemical Engineering at UNIST uncovers new ways to make biofuel from carbon dioxide (CO2), the most troublesome greenhouse gas. In their paper published in the journal Applied Catalysis B: Environmental, the team presented direct CO2 conversion to liquid transportation fuels by reacting with renewable hydrogen (H2) generated by solar water splitting.
