Our goosebumps are one of those weird quirks that make us human. (Credit: Michal Cervenansky/Shutterstock) Human bodies do a lot of weird stuff. But goosebumps may be one of our strangest bodily functions. Goosebumps are humanity's near-universal reaction to the cold. But for some reason, those unmistakable, tiny bumps on the skin also appear when we’re scared or when we’re moved by something awe-inspiring. What is it about these starkly different experiences that triggers ...read more

How Cell Membranes May Have Kicked Off the Origin of Life

(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

Astronomers Catch a Pulsar ‘Glitching,’ Offering Insights Into the Strange Stars

Posted on Categories Discover MagazineLeave a comment on Astronomers Catch a Pulsar ‘Glitching,’ Offering Insights Into the Strange Stars

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

Wicked Hot Boston: Urban Heat Island (UHI) Mapping

Posted on Categories Discover MagazineLeave a comment on Wicked Hot Boston: Urban Heat Island (UHI) Mapping

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

New SETI Project Will Practice Looking for Alien Life Near Deep-Sea Vents on Earth

InVADER will explore deep-sea vents on Earth to prepare future missions to do the same on watery worlds in the solar system like Europa or Enceladus. (Credit: D. Kelley, University of Washington/NSF-OOI/WHOI) Some of the most intriguing possibilities for finding life outside Earth are on water worlds like Europa or Enceladus — ocean moons orbiting Jupiter and Saturn. However, those worlds are encased in layers of ice, meaning any ocean exploration will take place far beneath the surface ...read more

The biofluorescent shark Scyliorhinus retifer. (Credit: David Gruber) (Inside Science) -- When we look at the seafloor, we might not see the bottom-dwelling sharks that blend in with the rocks and the sand. But to other sharks of the same species, they stand out like green glow sticks. Now scientists know how. In 2014, marine biologist David Gruber, from the City University of New York, and his team discovered that two species of bottom-dwelling sharks are biofluorescent. The swell shark ...read more

Ancient African Ancestors Lived In High Mountains, Ate Rodents of Unusual Size

Ethiopia's Bale Mountains. (Credit: Michele Alfieri/Shutterstock) High-altitude environments are not exactly welcoming places to call home. It’s hard to breathe, there’s little shelter and being that much closer to the sun means more exposure to UV radiation. The inhospitable conditions are why high mountains and plateaus were some of the last places on Earth humans occupied.  Now researchers find prehistoric humans lived in a high-altitude rocky outcrop in Ethiopia’ ...read more
