Saturated soils could impact survival of young trees planted to address climate change      (via sciencedaily.com)     Original source 

New research has looked into the potential effects of increased rainfall in regions being earmarked for expansion of temperate rainforests. Amid global calls for more trees to be planted as part of efforts to combat climate change, this study highlights the importance of factoring in soil conditions when looking at where and how to create the temperate rainforests of the future.

Swarms of miniature robots clean up microplastics and microbes, simultaneously      (via sciencedaily.com)     Original source 

When old food packaging, discarded children's toys and other mismanaged plastic waste break down into microplastics, they become even harder to clean up from oceans and waterways. These tiny bits of plastic also attract bacteria, including those that cause disease. Researchers describe swarms of microscale robots (microrobots) that captured bits of plastic and bacteria from water. Afterward, the bots were decontaminated and reused.

'Better than graphene' material development may improve implantable technology      (via sciencedaily.com)     Original source 

Move over, graphene. There's a new, improved two-dimensional material in the lab. Borophene, the atomically thin version of boron first synthesized in 2015, is more conductive, thinner, lighter, stronger and more flexible than graphene, the 2D version of carbon. Now, researchers have made the material potentially more useful by imparting chirality -- or handedness -- on it, which could make for advanced sensors and implantable medical devices.

Researchers 'unzip' 2D materials with lasers      (via sciencedaily.com)     Original source 

Researchers used commercially available tabletop lasers to create tiny, atomically sharp nanostructures in samples of a layered 2D material called hexagonal Boron Nitride (hBN). The new nanopatterning technique is a simple way to modify materials with light--and it doesn't involve an expensive and resource-intensive clean room.

Sugar-based catalyst upcycles carbon dioxide      (via sciencedaily.com)     Original source 

New catalyst is made from an inexpensive, abundant metal and table sugar. Catalyst converts carbon dioxide (CO2) into carbon monoxide, a building block for producing a variety of useful chemicals including syngas. With recent advances in carbon capture technologies, post-combustion carbon capture is becoming a plausible option to help tackle the global climate change crisis. But how to handle the captured carbon remains an open-ended question. The new catalyst potentially could provide one solution for disposing the potent greenhouse gas by converting it into a more valuable product.

Protecting endangered monkeys from poachers, habitat loss      (via sciencedaily.com)     Original source 

The 17 species of red colobus monkey living across Africa, including in the Tai Project field station region, have been singled out by scientists as a priority conservation target. Protection of these monkeys, they assert, can be expected to produce benefits throughout tropical African forests where hunting and climate change have led to dramatic wildlife and habitat loss.

Hornets found to be primary pollinators of two Angelica species      (via sciencedaily.com)     Original source 

Researcher discovered that two species in the genus Angelica are pollinated primarily by hornets. This overturns the conventional belief that Angelica species are 'generalists,' meaning that there is not one primary pollinator but a variety of species. As hornets are rarely primary pollinators, the discovery also impacts future ecological research and conservation efforts.

Speeding up spectroscopic analysis      (via sciencedaily.com)     Original source 

Ultrafast laser spectroscopy allows the ascertainment of dynamics over extremely short time scales, making it a very useful tool in many scientific and industrial applications. A major disadvantage is the considerable measuring time this technique usually requires, which often leads to lengthy acquisition times spanning minutes to hours. Researchers have now developed a technique to speed up spectroscopic analysis.
