A 2010 NASA study that suggested a bacterium could thrive on arsenic instead of phosphorus is refuted by two new pieces of research.
A recently discovered microbe has DNA unlike any other life form on Earth. It is able to substitute arsenic for phosphorus, and it may help us understand how life could prosper elsewhere.
A star chemistry student offers a periodic table joke beyond any other. Some don't get it -- at first.
A woman's children find hamburger patty-sized rocks on a California beach. They like them, so she puts them in her pocket. Shortly afterward, her pocket catches fire and she suffers serious burns.
A team of researchers has shown that it is possible to fabricate low-resistivity nanowires at the smallest scales imaginable by stringing together individual atoms in silicon.
Soil samples analysed by the Curiosity Mars rover have revealed evidence that the red planet could have once supported microbial life.
Venture-backed Ostara Nutrient Recovery Technologies to open a facility that converts wastewater from sewage treatment plants into fertilizer while reducing nutrient run-off.
NASA gets us one step closer to answering the big question of whether life ever existed on the Red Planet.
Seeking to keep Moore's Law on pace, researchers have developed a repeatable technique for assembling a single-atom version of the transistor--the building block of semiconductors and computers.
Toyota today announced that it will conduct a voluntary safety recall involving about 245,000 Lexus vehicles to inspect fuel pressure sensor installation. It is also recalling 1.3 million vehicles in Europe and Asia for a separate issue.
