Mechanism of bio-inspired control of liquid flow      (via sciencedaily.com)     Original source 

The more we discover about the natural world, the more we find that nature is the greatest engineer. Past research implied that liquids can only be transported in fixed direction on species with specific liquid communication properties and cannot switch the transport direction. Recently, researchers have shown that an African plant controls water movement in a previously unknown way -- and this could inspire breakthroughs in a range of technologies in fluid dynamics and nature-inspired materials, including applications that require multistep and repeated reactions, such as microassays, medical diagnosis and solar desalination etc.

Using visible light to make pharmaceutical building blocks      (via sciencedaily.com)     Original source 

Chemists have discovered a way to use visible light to synthesize a class of compounds particularly well suited for use in pharmaceuticals. The class of compounds, called azetidines, had been previously identified as a good candidate to build therapeutic drugs, but the compounds are difficult to produce in chemical reactions. Now, a team has developed a method to produce a specific class of azetidines called monocyclic azetidines using visible light and a photocatalyst.

Exploring the chemical space of the exposome: How far have we gone?      (via sciencedaily.com)     Original source 

Scientists have taken on the daunting challenge of mapping all the chemicals around us. They take inventory of the available science and conclude that currently a real pro-active chemical management is not feasible. To really get a grip on the vast and expanding chemical universe, they advocate the use of machine learning and AI, complementing existing strategies for detecting and identifying all molecules we are exposed to.

Novel spectroscopy technique sheds light on NOx reduction      (via sciencedaily.com)     Original source 

The process that can convert pollution into benign by-products is called selective catalytic reduction, or SCR. Until now, it has been unclear how this reaction actually occurs, and contradictions have long existed between reaction models within the literature. Catalysis researchers used a technology called modulation excitation spectroscopy, or MES, to finally identify the correct pathway.

Melanin from cuttlefish ink as a sustainable biomass resource      (via sciencedaily.com)     Original source 

Melanin is a ubiquitous compound in nature, produced by many organisms. However, its potential as a biomass resource to produce value-added chemicals and materials remains relatively unexplored. In a recent study, researchers investigated the chemical decomposition of melanin derived from cuttlefish ink and showcased its application in the synthesis of biopolymer films and particles. Their efforts will hopefully pave the way to the adoption of melanin upcycling.

This desert moss has the potential to grow on Mars      (via sciencedaily.com)     Original source 

The desert moss Syntrichia caninervis is a promising candidate for Mars colonization thanks to its extreme ability to tolerate harsh conditions lethal to most life forms. The moss is well known for its ability to tolerate drought conditions, but researchers now report that it can also survive freezing temperatures as low as 196 C, high levels of gamma radiation, and simulated Martian conditions involving these three stressors combined. In all cases, prior dehydration seemed to help the plants cope.

First specific PET scan for TB could enable more effective treatment      (via sciencedaily.com)     Original source 

A more accurate way to scan for tuberculosis (TB) has been developed, using positron emission tomography (PET). The team has developed a new radiotracer, which is taken up by live TB bacteria in the body. Radiotracers are radioactive compounds which give off radiation that can be detected by scanners and turned into a 3D image. The new radiotracer, called FDT, enables PET scans to be used for the first time to accurately pinpoint when and where the disease is still active in a patient's lungs.
