Biologists discover bees to be brew masters of the insect world      (via sciencedaily.com)     Original source 

Scientists have made a remarkable discovery about cellophane bees -- their microbiomes are some of the most fermentative known from the insect world. These bees, which are named for their use of cellophane-like materials to line their subterranean nests, are known for their fascinating behaviors and their important ecological roles as pollinators. Now, researchers have uncovered another aspect of their biology that makes them even more intriguing.

Chitin from consuming insects can help both gut microbiota and global health      (via sciencedaily.com)     Original source 

Increased insect consumption by humans may be better for both gut health and planetary health. Chitin (kai'tin) and healthy fats from insects appear to contribute to healthy gut microbiota and are strong sources of protein and nutrients, according to a recent paper.

African penguins: Climate refugees from a distant past?      (via sciencedaily.com)     Original source 

Imagine the view from the western coastline of southern Africa during the Last Glacial Maximum (LGM) over twenty thousand years ago: in the distance you would see at least fifteen large islands -- the largest 300 square kilometers in area -- swarming with hundreds of millions of marine birds and penguin colonies.

Nature's chefs: Scientists propose food-making as means of understanding species interactions      (via sciencedaily.com)     Original source 

An interdisciplinary group of researchers is proposing a new way to think of some interactions between species, classifying a variety of plants, animals and fungi as 'nature's chefs.' Specifically, nature's chefs are organisms that provide food -- or the illusion of food -- to other organisms. The concept offers a new perspective on species interactions, which can inform how people think about food across the tree of life as well as disparate research disciplines.

Why this bird flu is different: Scientists say new avian influenza requires urgent coordinated response      (via sciencedaily.com)     Original source 

A new study tracks arrival and spread of highly pathogenic Avian Influenza (H5N1) decimating wild birds, impacting poultry and pushing up egg prices. The team found that the deadly impact on wild birds and a shift from seasonal to year-round infections signal dangerous changes in avian influenza in the U.S.

New findings pave the way for stable organic solar cells that may enable cheap and renewable electricity generation      (via sciencedaily.com)     Original source 

Organic solar cells show great promise for clean energy applications. However, photovoltaic modules made from organic semiconductors do not maintain their efficiency for long enough under sunlight for real world applications. Scientists have now revealed an important reason why organic solar cells rapidly degrade under operation. This new insight will drive the design of more stale materials for organic semiconductor-based photovoltaics, thus enabling cheap and renewable electricity generation.

Stronger paper bags, reused repeatedly then recycled for biofuel could be future      (via sciencedaily.com)     Original source 

As the world searches for ways to reduce the use of plastics such as single-use plastic bags, a novel study demonstrates a process to make paper bags stronger -- especially when they get wet -- to make them a more viable alternative.

X-ray analysis sheds new light on prehistoric predator's last meal      (via sciencedaily.com)     Original source 

We now know more about the diet of a prehistoric creature that grew up to two and a half meters long and lived in Australian waters during the time of the dinosaurs, thanks to the power of x-rays. Researchers used micro-CT scans to peer inside the fossilized stomach remains of a small marine reptile -- a plesiosaur nicknamed 'Eric' after a song from the comedy group Monty Python -- to determine what the creature ate in the lead up to its death.

How does a millipede get its legs?      (via sciencedaily.com)     Original source 

Millipede legs grow in an unexpected way, according to new research. Previously, it was thought that when a millipede molts (sheds its exoskeleton), it grows new segments on the end of its body without legs. Then after the next molt, the previously new segments re-emerge with fully formed legs attached. However, a team has found that new segments actually contain tiny bundles of legs, which appear as transparent protrusions before molting and then become fully formed afterwards. This discovery could help us understand how not only millipedes, but also other arthropods (invertebrates with jointed legs) grow.

Using machine learning to find reliable and low-cost solar cells      (via sciencedaily.com)     Original source 

Hybrid perovskites are organic-inorganic molecules that have received a lot of attention over the past 10 years for their potential use in renewable energy. Some are comparable in efficiency to silicon for making solar cells, but they are cheaper to make and lighter, potentially allowing a wide range of applications, including light-emitting devices. However, they tend to degrade way more readily than silicon when exposed to moisture, oxygen, light, heat, and voltage. Researchers used machine learning and high-throughput experiments to identify perovskites with optimal qualities out of the very large field of possible structures.

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.

SpyLigation uses light to switch on proteins      (via sciencedaily.com)     Original source 

Scientists can now use light to activate protein functions both inside and outside of living cells. The new method, called light-activated SpyLigation, can turn on proteins that are normally off to allow researchers to study and control them in more detail. This technology has potential uses in tissue engineering, regenerative medicine, and understanding how the body works. The scientists applied their new method to control the glow of a green fluorescent protein derived from Japanese eel muscle.
