Solar-light-driven fully integrated microfluidic device could serve as autonomous fuel-cell-based power source for microsensors or lab-on-a-chip applications

Miniaturized devices such as microsensors often require an independent, equally miniaturized power supply. Searching for suitable systems, scientists have now developed a fully integrated microfluidic device that produces hydrogen fuel and converts it into electrical energy based on photocatalysis. It works fully autonomously and delivers enough hydrogen energy to power a microsensor for daily data transmission.

Large Canadian Arctic climate change study cancelled due to climate change

The Science Team of the Canadian Research Icebreaker CCGS Amundsen has cancelled the first leg of the 2017 Expedition due to complications associated with the southward motion of hazardous Arctic sea ice, caused by climate change.

Birds of a feather

Biologists have always been fascinated by the diversity and changeability of life on Earth and have attempted to answer a fundamental question: How do new species originate? A new study provides the first large-scale test of the link between population differentiation rates and speciation rates. The results confirm the evolutionary importance of population genetic differentiation.

Plastic made from sugar and carbon dioxide

Some biodegradable plastics could in the future be made using sugar and carbon dioxide, replacing unsustainable plastics made from crude oil.

"New Research Initiative to Update and Improve the Social Cost of Carbon"

From the inbox;

Resources for the Future (RFF) is launching a multi-year, multidisciplinary research initiative to improve the methodology used to calculate the social cost of carbon—an economic tool used to quantify both the benefits to society of reducing carbon dioxide emissions from the atmosphere and the harm to society from emitting more carbon dioxide.

Winning climate strategy demands details

Examining the daily minutia of climate, not just temperature, but also sunshine, precipitation and soil moisture simultaneously all over a country gives a better understanding of how variable a land's climate can be. That information is crucial when countries are setting policies aimed at growing food, protecting water supplies and the environment and stemming disease outbreaks.

Surprise just beneath the surface in carbon dioxide experiment

When a carbon dioxide experiment didn't match with what theorists predicted, researchers went back to the drawing board and discovered something new.

Lab on a chip could monitor health, germs and pollutants

Imagine wearing a device that continuously analyzes your sweat or blood for different types of biomarkers, such as proteins that show you may have breast cancer or lung cancer. Engineers have invented biosensor technology -- known as a lab on a chip -- that could be used in hand-held or wearable devices to monitor your health and exposure to dangerous bacteria, viruses and pollutants.

Late-nesting birds, bees face habitat threat

Bird and bumblebee species that nest late in the year are suffering more from the destruction of habitats, new research suggests. With habitats such as hedgerows and hay meadows in decline in many countries, fewer nest sites are available -- leading to more competition.

Genetic differences across species guide vocal learning in juvenile songbirds

Juvenile birds discriminate and selectively learn their own species’ songs even when primarily exposed to the songs of other species, but the underlying mechanism has remained unknown. A new study shows that song discrimination arises due to genetic differences between species, rather than early learning or other mechanisms.

Worldwide hotspots for alien plants and animals: Islands and coastal regions

The distribution of established alien species in different regions of the world varies significantly. Until now, scientists were uncertain about where the global hotspots for established alien species are located. Most alien species can be found on islands and coastal regions.

Volcanic 'plumerang' could impact human health

A new study has found a previously undetected potential health risk from the high concentration of small particles found in a boomerang-like return of a volcanic plume.
