Quantum chemistry: Molecules caught tunneling      (via sciencedaily.com) 

Quantum effects can play an important role in chemical reactions. Physicists have now observed a quantum mechanical tunneling reaction in experiments. The observation can also be described exactly in theory. The scientists provide an important reference for this fundamental effect in chemistry. It is the slowest reaction with charged particles ever observed.

Degrading modified proteins could treat Alzheimer's, other 'undruggable' diseases      (via sciencedaily.com) 

Certain diseases, including Alzheimer's, are currently considered 'undruggable' because traditional small molecule drugs can't interfere with the proteins responsible for the illnesses. But a new technique that specifically targets and breaks apart certain proteins -- rather than just interfering with them -- may offer a pathway toward treatment. Researchers have now designed a compound that targets and breaks down a post-translationally modified protein closely associated with Alzheimer's disease.

New superacid converts harmful compounds into sustainable chemicals      (via sciencedaily.com) 

Researchers have succeeded in producing very special catalysts, known as 'Lewis superacids', which can be used to break strong chemical bonds and speed up reactions. The production of these substances has, until now, proven extremely difficult. The chemists' discovery enables non-biodegradable fluorinated hydrocarbons, similar to Teflon, and possibly even climate-damaging greenhouse gases, such as sulphur hexafluoride, to be converted back into sustainable chemicals.

Chaos on the nanometer scale      (via sciencedaily.com) 

Chaotic behavior is typically known from large systems: for example, from weather, from asteroids in space that are simultaneously attracted by several large celestial bodies, or from swinging pendulums that are coupled together. On the atomic scale, however, one does normally not encounter chaos -- other effects predominate. Now scientists have been able to detect clear indications of chaos on the nanometer scale -- in chemical reactions on tiny rhodium crystals.

Novel air filter captures wide variety of pollutants      (via sciencedaily.com)     Original source 

An air filter made out of corn protein instead of petroleum products can concurrently capture small particulates as well as toxic chemicals like formaldehyde that current air filters can't. The research could lead to better air purifiers, particularly in regions of the world that suffer from very poor air quality. The more environmentally friendly air filter was able to simultaneously capture 99.5% of small particulate matter, similar to commercial HEPA filters, and 87% of formaldehyde, which is higher than specially designed air filters for those types of toxics.

RNAs can wreak havoc on cells if they aren't removed at the right time. Dis3L2 is a molecular 'machine' that untangles and chews up RNAs, but scientists have been unable to explain how. Biochemists have now pieced together the answer. By shape-shifting, the machine unsheathes a lethal wedge that pries open and chews up RNA molecules, a behavior previously unseen.

'Electronic nose' built with sustainably sourced microbial nanowires that could revolutionize health monitoring      (via sciencedaily.com) 

Scientists recently announced the invention of a nanowire 10,000 times thinner than a human hair that can be cheaply grown by common bacteria and tuned to 'smell' a vast array of chemical tracers -- including those given off by people afflicted with a wide range of medical conditions, such as asthma and kidney disease. Thousands of these specially tuned wires, each sniffing out a different chemical, can be layered onto tiny, wearable sensors, allowing healthcare providers an unprecedented tool for monitoring potential health complications. Since these wires are grown by bacteria, they are organic, biodegradable and far greener than any inorganic nanowire.
