  • Citizen scientists discover five tightly packed exoplanets

    Five new planets have been discovered outside our solar system, all orbiting a sun-like star located within the constellation Aquarius, nearly 620 light years from Earth. The alien worlds are considered super-Earths, sizing in at two to three times larger than our own blue planet.All five exoplanets are likely scorchingly hot: Each planet comes incredibly close to its star, streaking around in just 13 days at most — a whirlwind of an orbit compared with Earth’s 365-day year.

  • Peel-and-go printable structures fold themselves

    As 3-D printing has become a mainstream technology, industry and academic researchers have been investigating printable structures that will fold themselves into useful three-dimensional shapes when heated or immersed in water.In a paper appearing in the American Chemical Society’s journal Applied Materials and Interfaces, researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) and colleagues report something new: a printable structure that begins to fold itself up as soon as it’s peeled off the printing platform.

  • Zeroing in on the chemistry of the air

    We breathe it in and out every few seconds, yet the air that surrounds us has chemical activity and variations in its composition that are remarkably complex. Teasing out the mysterious behavior of the atmosphere’s constituents, including pollutants that may be present in tiny amounts but have big impacts, has been the driving goal of Jesse Kroll’s research.
