(Credit: NASA's Goddard Space Flight Center Conceptual Image Lab) (Inside Science) -- Experts believe the building blocks of life first bumped into each other about 3.5 billion years ago. This serendipitous collision somehow helped form the first rudimentary cell -- and the first life on Earth. At least, that's been the predominant theory. Now, a team of scientists from the University of Washington is challenging this idea in a paper published in the journal Proceedings of the National Ac ...read more

The Vela pulsar is known to glitch something like once every three years, when it speeds up for a few seconds. (Credit: X-ray: NASA/CXC/Univ of Toronto/M.Durant et al; Optical: DSS/Davide De Martin) When a massive star dies, it leaves behind a dense core called a neutron star. Many of these exotic suns spin rapidly, sending out beams of radiation like lighthouses, and these are called pulsars. They can rotate thousands of times a second, and spin so steadily that they can be used as cosmolog ...read more

Want to map extreme heat in your community? Anyone, anywhere can take action with ISeeChange. It’s not just in your head; Boston really is hotter in the summer. When urban areas are warmer than surrounding non-urban environments, we experience a phenomenon called the urban heat island (UHI) effect. Cities are filled with large amounts of artificial materials, such as concrete and asphalt, that absorb heat throughout the day and release heat at night. Living materials like trees, flo ...read more
