Remarkable enzyme points the way to reducing nitric acid use in industry
An enzyme in the bacterium that causes potato scab could help create new, environmentally-benign biocatalysts with the potential to cut use of the highly corrosive chemical nitric acid.
Chemist develops new synthesis of most useful, yet expensive, antimalarial drug
In 2010 malaria caused an estimated 665,000 deaths, mostly among African children. Now, chemists at Indiana University have developed a new synthesis for the world's most useful antimalarial drug, artemisinin, ...
Luminescent ink from eggs
(Phys.org)—Luminescent carbon nanoparticles based on carbon exhibit advantageous optical properties. They are also biocompatible, and therefore better suited for imaging procedures in the biosciences than ...
Ants have an exceptionally 'hi-def' sense of smell
The first complete map of the ants' olfactory system has discovered that the eusocial insects have four to fives more odorant receptors—the special proteins that detect different odors—than other insects.
Weapon-wielding marine microbes may protect populations from foes
Competition is a strong driving force of evolution for organisms of all sizes: Those individuals best equipped to obtain resources adapt and reproduce, while others may fall by the wayside. Many organisms—mammals, ...
Chemical use inflicts mounting bill on poor countries: UN
The spiralling use of chemicals, especially in developing countries, is inflicting a rising bill by damaging people's health and the environment, according to a UN report issued on Wednesday.
"Green walls" against air pollution
(Phys.org)—Planting vegetation along streets in the city might reduce air pollution better than assumed so far, that is by up to 30 percent instead of one to two percent. This finding was made by Dr. Thomas Pugh, now working ...
'Promiscuous' enzymes still prevalent in metabolism
Open an undergraduate biochemistry textbook and you will learn that enzymes are highly efficient and specific in catalyzing chemical reactions in living organisms, and that they evolved to this state from ...
Unexpected finding shows fungi may not help store climate change's extra carbon
Fungi found in plants may not be the answer to mitigating climate change by storing additional carbon in soils as some previously thought, according to an international team of plant biologists.
'Google on steroids': Scientists create chemical brain
Northwestern University scientists have connected 250 years of organic chemical knowledge into one giant computer network -- a chemical Google on steroids. This "immortal chemist" will never retire and take away its knowledge ...
Researchers find evidence of photosynthesis-like process in aphids
Inspired by genetics, chemistry finally takes hold of its own code
Nature proves every day that it is both complex and efficient. Organic chemists are envious of it; their conventional tools confine them to simpler achievements. Thanks to the work of professor Stefan Matile's team from the ...
First single-molecule measurement of Van Der Waals interactions at metal-organic interface
A team of researchers at Columbia Engineering, led by Applied Physics and Applied Mathematics Associate Professor Latha Venkataraman and in collaboration with Mark Hybertsen from the Center for Functional ...
Researchers collect and reuse enzymes while maintaining bioactivity
Clemson University researchers are collecting and harvesting enzymes while maintaining the enzyme's bioactivity. Their work, a new model system that may impact cancer research, is published in the journal Small.
