Researchers find way to kill pathogen resistant to antibiotics

24-Sep-2019

Pseudomonas aeruginosa is a dangerous bacterium that causes infections in hospital settings and in people with weakened immune systems. It can cause blood infections and pneumonia, while severe infections can be deadly. Highly resistant to antibiotic treatment, P. aeruginosa is one of the most ...

Let there be light: Synthesizing organic compounds

23-Sep-2019

Every biological reaction is a chemical reaction. The exchange of carbon dioxide for oxygen in our lungs and blood cells, for example, is caused by molecules releasing chemicals and reforming with new ones. The uncontrolled replication of cancerous cells is the result of broken chemical compounds ...

Microorganisms build the best fuel efficient hydrogen cells

21-Aug-2019

For all the advances technology has made throughout our lives, in many cases it stands behind what nature can do. Ants can carry 5000 times their weight, and spider webs are five times stronger than steel. Fuel efficiency is no different. In a new study seen in Angewandte Chemie International ...

ELSI scientists discover new chemistry that may help explain the origins of cellular life

Chemists find simplest organic molecules can self-assemble to give cell-like structures under early Earth conditions

25-Jul-2019

Before life began on Earth, the environment likely contained a massive number of chemicals that reacted with each other more or less randomly, and it is unclear how things as complex as cells could have emerged from such chemical chaos. Now, a team led by Tony Z. Jia of the Earth-Life Science ...
