The next generation of solar energy collectors could be rocks      (via sciencedaily.com)     Original source 

The next generation of sustainable energy technology might be built from some low-tech materials: rocks and the sun. Using a new approach known as concentrated solar power, heat from the sun is stored then used to dry foods or create electricity. A team has found that certain soapstone and granite samples from Tanzania are well suited for storing this solar heat, featuring high energy densities and stability even at high temperatures.

Quantum scientists accurately measure power levels one trillion times lower than usual      (via sciencedaily.com)     Original source 

Scientists have developed a nanodevice that can measure the absolute power of microwave radiation down to the femtowatt level at ultra-low temperatures -- a scale trillion times lower than routinely used in verifiable power measurements. The device has the potential to significantly advance microwave measurements in quantum technology.

How a drought affects trees depends on what's been holding them back      (via sciencedaily.com)     Original source 

Droughts can be good for trees. Certain trees, that is. Contrary to expectation, sometimes a record-breaking drought can increase tree growth. Why and where this happens is the subject of a new article.

'Improved' cookstoves emit more ultrafine particles than conventional stoves      (via sciencedaily.com)     Original source 

Improved cookstoves, which are widely used for cooking in developing countries, produce twice as many harmful ultrafine air pollution particles (PM0.1) as conventional stoves, according to a new study.

Preserving pine forests by understanding beetle flight      (via sciencedaily.com)     Original source 

Researchers study the flight performance of the mountain pine beetle from a fluid mechanics and an entomological perspective. Understanding these aspects of the insect's flight could improve estimates of its spread through the environment and preserve pine forests. To examine insect flight, the team employed a type of model previously used for idealized airfoils. They showed that it can be successfully applied to multiple individual animals across biological sex, insect age, and body size. In doing so, the model can predict how these factors impact flight characteristics.

Exploring the underground connections between trees      (via sciencedaily.com)     Original source 

Fungal networks interconnecting trees in a forest is a key factor that determines the nature of forests and their response to climate change. These networks have also been viewed as a means for trees to help their offspring and other tree-friends, according to the increasingly popular 'mother-tree hypothesis'. An international group of researchers re-examined the evidence for and against this hypothesis in a new study.

Mushrooms and their post-rain, electrical conversations      (via sciencedaily.com)     Original source 

Certain types of fungi can communicate with each other via electrical signals. But much remains unknown about how and when they do so. A group of researchers recently headed to the forest to measure the electrical signals of Laccaria bicolor mushrooms, finding that their electrical signals increased following rainfall.

Ant mounds are more important for biodiversity than previously thought      (via sciencedaily.com)     Original source 

The ant mounds on the heath, in the forest and in your garden are oases for life. The heat and nutrients from ant mounds make them the perfect home for unique plant and animal species, according to new research.

How the Amazon rainforest is likely to cope with the effect of future drought      (via sciencedaily.com)     Original source 

A major collaboration involving 80 scientists from Europe and South America has identified the regions of the Amazon rainforest where trees are most likely to face the greatest risk from drier conditions brought about by climate change. Based on the analysis, the scientists predict trees in the western and southern Amazon face the greatest risk of dying. They also warn that previous scientific investigations may have underestimated the impact of drought on the rainforest because those studies focused on the central-eastern part of the forest, which is the least vulnerable to drought.

Even as temperatures rise, this hydrogel material keeps absorbing moisture      (via sciencedaily.com)     Original source 

Engineers find the hydrogel polyethylene glycol (PEG) doubles its water absorption as temperatures climb from 25 to 50 C, and could be useful for passive cooling or water harvesting in warm climates.

Chemists propose ultrathin material for doubling solar cell efficiency      (via sciencedaily.com)     Original source 

Researchers are studying radical new ways to improve solar power and provide more options for the industry to explore. Chemists are proposing to make solar cells using not silicon, but an abundantly available natural material called molybdenum disulfide. Using a creative combination of photoelectrochemical and spectroscopic techniques, the researchers conducted a series of experiments showing that extremely thin films of molybdenum disulfide display unprecedented charge carrier properties that could someday drastically improve solar technologies.

The diversity of present tree species is shaped by climate change in the last 21,000 years      (via sciencedaily.com)     Original source 

A new global survey of 1000 forest areas shows how climate change since the peak of the last ice age has had a major impact on the diversity and distribution of tree species we see today. The results can help us predict how ecosystems will react to future changes, thus having an impact on conservation management around the globe.
