Martian meteorite upsets planet formation theory

A new study of an old meteorite contradicts current thinking about how rocky planets like the Earth and Mars acquire volatile elements such as hydrogen, carbon, oxygen, nitrogen and noble gases as they form. The work is published ...

Scientists begin studying 50-year-old frozen Apollo 17 samples

Scientists at NASA's Goddard Space Flight Center in Greenbelt, Maryland, recently received samples of the lunar surface that have been curated in a freezer at NASA's Johnson Space Center in Houston since Apollo 17 astronauts ...

Chemists develop new technology that detects algae crop health

Trained dogs are well known to use their acute sense of smell to identify explosives, contraband and even certain types of disease. Being able to automate such detection skills could be useful in a range of settings, from ...

Great potential in regulating plant greenhouse gas emissions

You cannot see them with the naked eye, but most plants emit volatile gases—isoprenoids—into the atmosphere when they breathe and grow. Some plants emit close to nothing; others emit kilograms annually.

A fundamental shortcoming in air pollution models

Researchers from the University of Copenhagen have discovered a surprising phenomenon in a process by which certain gas molecules produce harmful particles. The impact of this phenomenon is likely to increase in urban areas ...

Fracking likely to result in high emissions

Natural gas releases fewer harmful air pollutants and greenhouse gases than other fossil fuels. That's why it is often seen as a bridge technology to a low-carbon future. A new study by the Institute for Advanced Sustainability ...
