  • The Biology Of Race, Revisited

    The same goes for biologists like Stanford University's Dr. Marcus Feldman, who has done pioneering research on the differences between human populations. Recently, HuffPost Science posed several questions about race and racism to Feldman. Or have biologists discarded the term?

  • First Color Movies Of Pluto And Its Biggest Moon Will Wow You

    The brief animations--the mission's first color movies--show the complex "orbital dance" of Pluto and its biggest moon, Charon. One of the videos is centered on Pluto so that the dwarf planet appears stationary as Charon orbits it (below). The other presents a so-called barycentric view, meaning it shows Pluto and Charon moving around the center of gravity that the two bodies share.

  • Astronomers See Signs Of Universe's Earliest Stars

    The massive blue stars were observed in a number of young and very bright galaxies, including one dubbed CR7--a nod to the Portuguese soccer player Cristiano Ronaldo. "The discovery challenged our expectations from the start, as we didn't expect to find such a bright galaxy," Dr. David Sobral, an astrophysicist at the University of Lisbon in Portugal and leader of the team of astronomers who made the discovery, said in a written statement. Population III stars are those that formed from the primordial material left over after the Big Bang--the light elements hydrogen, helium, and lithium.

  • Spectacular Video Lets You Fly Around Ceres

    NASA has released a dramatic new video of the dwarf planet Ceres (above). It was assembled from 80 images taken by the space agency's Dawn spacecraft. "We used a three-dimensional terrain model that we had produced based on the images acquired so far," Ralf Jaumann, a Dawn team member with the German Aerospace Center in Berlin, said in a written statement.

  • Bright City Lights Mean Bad News For Urban Bats

    The nocturnal creatures are facing all sorts of potentially lethal threats, from climate change and habitat loss to white nose syndrome to the spinning blades of wind turbines. "The ability to freely move around is key to individual bat fitness and resilience of the broader bat population," James Hale, a research associate in the school of geography at the University of Birmingham in England and the study's lead author, said in a written statement. For the study, Hale and a group of colleagues that included scientists from Lancaster University conducted field observations of bats in England's West Midlands region.

  • Strange Spots On Mars Look Like Pools Of Water--But Aren't

    A startling new photograph of Mars shows beautiful blue pools of water just right for a refreshing swim--or so it seems. In fact, the blue regions in the image--which was taken by the European Space Agency's Mars Express orbiter--are dark sediments that look like liquid water because of the way the image was processed, according to the agency's website. Water is known to exist on Mars, but the Red Planet is so cold that, with the possible exception of some transient melting, it's all frozen solid.

  • Here's What The Solar System Looked Like As A 'Toddler'

    What did the solar system look like in its early days, and exactly how did it evolve? "It's almost like looking at the outer solar system when it was a toddler," Dr. Thayne Currie, an astronomer at the Subaru Observatory in Hawaii and the principal investigator of a new study about the star system, said in a written statement.

  • New Photo Shows Medusa Nebula Is Way Prettier Than Its Namesake

    Way out in space, some 1,500 light-years from Earth in the constellation Gemini, lies the Medusa Nebula--so named because its glowing snakelike filaments of gas resemble the serpents that crown the head of the the hideous Gorgon of Greek mythology. It was discovered in 1955 by American astronomer George O. Abell.

  • It's 'Serial Killers' vs. Cancer Cells In This Dramatic New Video

    Known as cytotoxic T cells, these cellular assassins--each about one-tenth the thickness of a strand of human hair--are constantly patrolling our bodies, seeking out and destroying cells that are cancerous or infected with dangerous viruses. Become a founding member of HuffPost Plus today. It shows T cells (orange or green blobs) encountering cancer cells (blue blobs) and injecting them with lethal proteins known as cytotoxins (red).

  • Discovery Of Rare Cosmic Quartet Baffles Astronomers

    Call it the cosmic equivalent of winning the lottery: for the first time ever, astronomers have discovered four of the rare, super-luminous celestial objects known as quasars arrayed in close proximity to one another. Quasars are typically separated by vast distances, and the discovery of this "quasar quartet" has been characterized as either a one-in-10-million coincidence or evidence that ideas about quasars need to be revised. In this false-color image, arrows indicate the four quasars that are embedded in a giant nebula of cool, dense gas (shown in blue).

  • Sun Fires Off Vast 'Filament' In Spectacular New Video

    WOW! The sun fired off a colossal filament on April 28-29, and the sun-watching Solar & Heliospheric Observatory (SOHO) spacecraft was able to catch the dramatic action in still images and video (see above). A solar filament is a strand of hot plasma suspended above the sun's surface by magnetic forces. A joint venture of NASA and the European Space Agency, SOHO was launched into orbit around the sun on Dec. 2, 1995.

  • Original 'War Of The World' Drawings Expected To Fetch Huge Sum

    If the drawings created for the 1906 edition of H.G. Wells' iconic science-fiction novel "The War of the Worlds" are any indication, it would be really, really bad. First published in book form in 1898, The War of the Worlds is one of the earliest stories to depict war between earthlings and aliens.

  • Astronomers Discover What May Be The Biggest Thing In The Universe

    The Cold Spot is in the constellation Eridanus. There's no barrier--it's just that the density of galaxies is significantly lower inside the supervoid than outside. "Supervoids are not entirely empty, they're under-dense," Dr. Andras Kovacs, of Eotvos Lorand University in Budapest, Hungary, and one of the researchers behind for the discovery, told Popular Science.

  • SpaceX Nails Launch, But Landing Attempt Fails Again

    After a one-day postponement, SpaceX is set to launch another cargo-laden unmanned rocket toward the International Space Station today--and to try again to land the first stage of its Falcon 9 booster rocket on a platform floating in the Atlantic off Florida's east coast. The launch is scheduled for 4:10 p.m. EDT from the Cape Canaveral Air Force Station in Florida. This will be the company's third try at landing a rocket on the platform, the Associated Press reported, its first step toward creating a reusable rocket that SpaceX CEO Elon Musk believes could reduce the cost of spaceflight by a factor of 100.

  • Aliens Might Be Way Bigger Than We Ever Imagined

    If such a being had human proportions, Simpson told The Huffington Post in an email, it would be taller than Robert Wadlow, who at 8 feet, 11 inches is believed to have been the tallest human who ever lived. Robert Wadlow (1918-1940), the tallest man who ever lived. Simpson's paper, which is posted on the online research repository arXiv.org, is chockablock with formidable-looking mathematical equations.

  • Vast Medieval Graveyard Discovered Beneath University Building

    A giant medieval graveyard containing the skeletal remains of more than a thousand people has been unearthed at the University of Cambridge in England. The site represents "one of the largest medieval hospital osteoarchaeological assemblages from the British Isles," Dr. Craig Cessford of the university's department of archaeology and anthropology and the leader of the dig, wrote in a report describing the excavation.

  • Human Waste May Be Flush With Gold And Other Valuable Metals

    "If you can get rid of some of the nuisance metals that currently limit how much of these biosolids we can use on fields and forests, and at the same time recover valuable metals and other elements, that's a win-win," Dr. Kathleen S. Smith, a research geochemist at the U.S. Geological Survey in Denver and one of the scientists, said in a written statement. The metal particles seen in biosolids are microscopically small--about 100 times smaller than the width of a human hair, Smith said at a March 24 press conference. Exactly how do these microscopic bits get into our poop in the first place?

  • Aha Moment Brings Better Way To Make World's Most Amazing Material

    Graphene just might be the world's most incredible material. It's also an excellent conductor of heat and electricity and is stretchable, flexible, transparent, and impermeable. All those and many more products may be available in the not-too-distant future, Dr. David A. Boyd, a staff scientist at the university and the researcher credited with developing the new graphene-making process, told The Huffington Post.
