Detecting climate change using aerosols      (via sciencedaily.com)     Original source 

Researchers analyzed long-term aerosol satellite observation big data focusing on the Pacific Ocean downwind of China. Using a newly developed metric that considered aerosols as tracers, they detected altered atmospheric transport patterns associated with climate change. They observed that the distance of transboundary air pollution moving east from China had shortened. Thus, long-term satellite-based Earth observations are crucial for early climate change detection and accurate evaluation of this trend.

3D-printed blood vessels bring artificial organs closer to reality      (via sciencedaily.com)     Original source 

Lab-grown organs are a long-time 'holy grail' of organ engineering that has yet to be achieved, but new research has brought that goal a big step closer to reality using a new 3D-printing method called co-SWIFT. co-SWIFT prints branching networks of double-layered vessels that are infused with smooth muscle cells and endothelial cells into living human cardiac tissue, and can even replicate patient-specific vascular structures,indicating that it could one day be used for personalized medicine.

Individuals vary in how air pollution impacts their mood      (via sciencedaily.com)     Original source 

Affective sensitivity to air pollution (ASAP) describes the extent to which affect, or mood, fluctuates in accordance with daily changes in air pollution, which can vary between individuals, according to a new study.

Forever chemical pollution can now be tracked      (via sciencedaily.com)     Original source 

Researchers developed a way to fingerprint organofluorine compounds -- sometimes called 'forever chemicals' --which could help authorities trace them to their source when they end up in aquifers, waterways or soil.

When mammoths roamed Vancouver Island      (via sciencedaily.com)     Original source 

Mammoths, the massive pre-historic ice age cousins of the modern-day elephant, have always been understood to have inhabited parts of British Columbia, but the question of when has always been a bit woolly. Now, a new study has given scientists the clearest picture yet when the giant mammals roamed Vancouver Island.

Scientists lay out revolutionary method to warm Mars      (via sciencedaily.com)     Original source 

Ever since we learned that the surface of planet Mars is cold and dead, people have wondered if there is a way to make it friendlier to life. The newly proposed method is over 5,000 times more efficient than previous schemes to globally warm Mars, representing a significant leap forward in our ability to modify the Martian environment.

Fishing is causing frightened fish to flee when they should flirt      (via sciencedaily.com)     Original source 

Populations of squaretail grouper face an uncertain future as new research shows fishing that targets their spawning sites is causing males to be repeatedly scared away from their territories during their short mating meet-ups. By fleeing for safety, individuals are losing valuable time to catch the eye and court female fish.

Social rank may determine if animals live fast, die young      (via sciencedaily.com)     Original source 

Social rank may determine whether animals prioritize immediate fitness over long-term health, according to a study. Researchers studied macaques on a Thai island and found that the animals' unusual habit of washing their food is in fact based on social rank. Dominant monkeys quickly brush their food on their fur before eating it, along with mouthfuls of tooth-degrading sand, while lower-ranked monkeys obsessively wash their food in the surf. Citing the disposable soma hypothesis, the researchers suggest that high-ranking macaques are looking to quickly consume energy to mate and fend off challengers. But food-washing monkeys may be preserving their long-term health to produce more offspring over time. The findings could shed light on how the wear observed in the fossilized teeth of early humans relates to social structure.

New device for on-the-spot water testing      (via sciencedaily.com)     Original source 

Researchers at University of Galway have developed a new, portable technology for on-the-spot testing of water quality to detect one of the most dangerous types of bacteria. Ireland regularly reports the highest crude incidence rates of the pathogen Shiga toxigenic Escherichia coli -- STEC for short -- in Europe over the recent years.

The world is going to need a lot of weird metals in the coming years, according to chemistry professor. But he isn't talking about lithium, cobalt or even beryllium. He's interested in dysprosium, which is so hidden in the periodic table that you'd be forgiven for thinking he made it up.

Soft gold enables connections between nerves and electronics      (via sciencedaily.com)     Original source 

Gold does not readily lend itself to being turned into long, thin threads. But researchers have now managed to create gold nanowires and develop soft electrodes that can be connected to the nervous system. The electrodes are soft as nerves, stretchable and electrically conductive, and are projected to last for a long time in the body.

Smallest arm bone in human fossil record sheds light on the dawn of Homo floresiensis      (via sciencedaily.com)     Original source 

A new study reports the discovery of extremely rare early human fossils from the Indonesian island of Flores, including an astonishingly small adult limb bone. Dated to about 700,000 years old, the new findings shed light on the evolution of Homo floresiensis, the so-called 'Hobbits' of Flores whose remains were uncovered in 2003 at Liang Bua cave in the island's west.
