Methylation and mopping up

LMU researchers have discovered a novel type of chemical modification in bacterial RNAs. The modification is apparently attached to molecules only when cells are under stress, and is rapidly removed during recovery.

How nitrogen-fixing bacteria sense iron

Researchers at the University of East Anglia have discovered how nitrogen-fixing bacteria sense iron—an essential but deadly micronutrient.

Scientists design organic cathode for high performance batteries

Researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have designed a new, organic cathode material for lithium batteries. With sulfur at its core, the material is more energy-dense, cost-effective, ...

New approach for solving protein structures from tiny crystals

Using x-rays to reveal the atomic-scale 3-D structures of proteins has led to countless advances in understanding how these molecules work in bacteria, viruses, plants, and humans—and has guided the development of precision ...

Research suggests life thrived on Earth 3.5 billion years ago

Three and a half billion years ago, Earth hosted life, but was it barely surviving, or thriving? A new study carried out by a multi-institutional team with leadership including the Earth-Life Science Institute (ELSI) of Tokyo ...

Chemists discover unexpected enzyme structure

Many microbes have an enzyme that can convert carbon dioxide to carbon monoxide. This reaction is critical for building carbon compounds and generating energy, particularly for bacteria that live in oxygen-free environments.

Simulations show how atoms behave inside self-healing cement

Researchers at Pacific Northwest National Laboratory (PNNL) have developed a self-healing cement that could repair itself in as little as a few hours. Wellbore cement for geothermal applications has a life-span of only 30 ...
