How metals work together to weaken hardy nitrogen-nitrogen bonds

Nitrogen, an element that is essential for all living cells, makes up about 78 percent of Earth's atmosphere. However, most organisms cannot make use of this nitrogen until it is converted into ammonia. Until humans invented ...

A more efficient, safer alternative to sourcing copper via bacteria

Copper remains one of the single most ubiquitous metals in everyday life. As a conductor of heat and electricity, it is utilized in wires, roofing and plumbing, as well as a catalyst for petrochemical plants, solar and electrical ...

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 ...
