New proxy reveals how humans have disrupted the nitrogen cycle

More and more, scientists are getting a better grip on the nitrogen cycle. They are learning about sources of nitrogen and how this element changes as it loops from the nonliving, such as the atmosphere, soil or water, to ...

Understanding nitric oxide toxicity

(PhysOrg.com) -- Researchers at MIT, the Japan Synchrotron Radiation Research Institute (JASRI), and the University of California at Davis have succeeded in characterizing the dinitrosyl iron complexes (DNICs) produced during ...

Watching Venus glow in the dark

(PhysOrg.com) -- ESA’s Venus Express spacecraft has observed an eerie glow in the night-time atmosphere of Venus. This infrared light comes from nitric oxide and is showing scientists that the atmosphere of Earth’s nearest ...

Biofriendly protocells pump up blood vessels

An international team comprising researchers from the University of Bristol, and Hunan and Central South Universities in China, have prepared biocompatible protocells that generate nitric oxide gas—a known reagent for blood ...

Developing an eco-friendly ammonia catalyst

A DGIST research team led by Professor Sangaraju Shanmugam, Department of Energy Engineering, developed a catalyst that converts nitric oxide (NO) to ammonia (NH3). This electrochemical technology offers high Faradaic efficiency ...

Exploring greener approaches to nitrogen fixation

About half of the nitrogen in our bodies today comes from bacteria via the enzyme nitrogenase, which converts, or "fixes," unreactive nitrogen gas in the atmosphere into a form that plants can use for growth. The other half ...

Microbes can grow on nitric oxide

Nitric oxide is a fascinating and versatile molecule, important for all living things as well as our environment. It is highly reactive and toxic; it is used as a signaling molecule; it depletes the ozone layer in our planet's ...

'Nanobionics' aims to give plants super powers

Plants are an engineering marvel of nature. Fueled by sunlight, they recycle our carbon dioxide waste into fresh oxygen for us to breathe. Plus, they make the world prettier. But, with a little help from us humans, can they ...
