New study strengthens olfactory vibration-sensing theory

(Phys.org)—A new study by a team of chemists in Greece has added credence to a theory that suggests that humans differentiate smells by sensing molecular vibrations, rather than through simple binding to receptors. In their ...

Solving mysterious enzyme structure

Scientists at the Max Planck Institute for Chemical Energy Conversion (MPI CEC) have solved a long-standing puzzle in photosynthesis research. With the aid of quantum chemistry they were able to provide unexpected insight ...

Key pathological mechanism found in plague bacterium

(Phys.org)—A more than 50-year-old question has now been answered. Chemists and microbiologists at the Biological Chemistry Center at Umeå University in Sweden are now able to describe in detail the role of calcium in ...

Breakthrough could help optimize capture of sugars for biofuels

(Phys.org)—Scientists at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) and the BioEnergy Science Center (BESC) combined different microscopic imaging methods to gain a greater understanding ...

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 ...
