Differences between Martian meteorites and rocks examined by a NASA rover can be explained if Mars had an oxygen-rich atmosphere 4,000 million years ago— well before the rise of atmospheric oxygen on Earth 2,500 million years ago.
Researchers using sound waves can place nanowires in repeatable patterns for potential use in a...
A new study confirms directly what scientists previously knew only indirectly: the poisonous “...
For all the parasites' collective contributions to biomass and biodiversity, conventional food webs don't account for the presence of these tiny and numerous consumers.
Long before Earth became lush, when life consisted of single-celled organisms afloat in a planet-wide sea, bacteria invaded the ancient ancestors of plants and animals and took up permanent residence.
Matthew Pasek and a team from the Univ. of South Florida found that reactive phosphorous— an essential component to creating life— came to Earth on meteorites.
Air pollution is related to forest decline and also appears to attack the protecting wax on tree leaves and needles.
In adding steam to benzene to generate hydrogen, the step that determines the reaction's speed is not the benzene's absorption onto the catalyst, but rather the first benzene bond that breaks.
A team of researchers has developed antibacterial compounds— derived from the outer coating of HIV— that could be potential treatments for drug-resistant bacterial infections and appear to avoid generating resistance.
METTLER TOLEDO subsidiary Rainin Instrument has launched a new program to encourage its customers to reuse the heavy-duty cardboard return kits it sends to those who request mail-in service for their pipettes.
Inside you will find articles about modern lab lighting, a new category of R&D informatics solutions and how to stay business transformation-ready. There is also a guide to safely evaporating samples and an article about how old problems inform new solutions. And don't forget about the departments like Spotlight on Science, World Web Watch, Top 10 and Product Corners.
Taking inspiration from trees, scientists have developed a battery made from a sliver of wood coated with tin that shows promise for becoming a tiny, long-lasting, efficient and environmentally friendly energy source.
Researchers have made the first direct images of electrical currents flowing along the edges of a topological insulator– a recently discovered state of matter with potential applications in information technology.
High-definition video images acquired by Chinese submersible Jiaolong show brown mussels dotting the area around the cold vent some 1,500 meters under water during its manned dive mission in the South China Sea.
The most detailed record of cloud motion in the atmosphere of Venus has revealed that the planet’s winds have steadily been getting faster over the last six years.
Researchers have found an effective solution for collecting sunlight for artificial photosynthesis. By combining self-assembling DNA molecules with simple dye molecules, they have created a system that resembles nature's own antenna system.
A new technique enables the conversion of an ordinary camera into a light-field camera capable of recording high-resolution, multiperspective images.
