Scientists perform computational simulations for biological molecules detected in meteorites to clarify the origin of life on Earth. All biological amino acids on Earth appear exclusively in their left-handed form, but the reason underlying…

To produce its many functions, including thought, the brain works at many scales. Information such as goals or images is represented by coordinated electrical activity among networks of neurons, while within and around each neuron a mix of…

Proteins that act like air traffic controllers, managing the flow of signals in and out of human cells, have been observed for the first time with unprecedented detail using advanced microscopy techniques. Described in new research…

The beauty and wellness platform behind Il Makiage and Spoiled Child is investing more than $100 million to acquire a biotech startup and open a U.S.-based lab in a bid to make the most effective cosmetic products on the market, the company…

The skin is an appealing route for drug delivery because it allows drugs to go directly to the site where they're needed, which could be useful for wound healing, pain relief, or other medical and cosmetic applications. However, delivering…

To get therapies into the brain after a stroke, researchers are increasingly making use of the blood-brain barrier, which allows only certain molecules to pass from the blood into the brain. In a study published earlier this year in…

Twisted molecules play an important role in the development of organic light-emitting diodes. A team of chemists has managed to create these compounds with exactly the three-dimensional structure that they wanted. In so doing, they are…

The scientists Susan Iglesias-Groth, of the Instituto de Astrofísica de Canarias (IAC), and Martina Marín-Dobrincic, of the Polytechnic University of Cartagena, have discovered the presence of numerous prebiotic molecules in the star…

The ability to distinguish two chiral enantiomers is an essential analytical capability for chemical industries including pharmaceutical companies, flavor/odor engineering and forensic science. A new wave of chiral optical methods have…

Tunneling reactions in chemistry are very difficult to predict. The quantum mechanically exact description of chemical reactions with more than three particles is difficult, with more than four particles it is almost impossible. Theorists…
