    Paleontologists have long wondered about the skeletons of a strange, ancient fish family called heterostracan. But now UK scientists say they’ve cracked it, declaring the 400 million-year-old fossils to be the oldest examples of bone ever found.
  • By their nature, stars burn bright – so when they start dimming and fading, scientists pay attention. Now, astronomers have observed a strangely-twinkling star and found that it might be the result of a collision between proto-planets orbiting it, and the star gobbling up the remains.
  • Researchers at CNBP have developed a new targeted treatment for cancer. Chemotherapy drugs are wrapped in “nano-bubbles” called liposomes, which are then injected into the desired part of the body and made to release their payload on demand, by applying X-ray radiation.
  • Medical X-ray scans have long been stuck in the black-and-white era. Now Mars Bioimaging has developed a bioimaging scanner that can produce full color, three dimensional images of bones, lipids, and soft tissue, thanks to a sensor chip developed at CERN for use in the Large Hadron Collider.
  • Ordinary (or baryonic) matter is relatively rare in the universe, and there seems to be a huge chunk of it missing. After 20 years of scouring the sky, astronomers using the ESA’s XMM-Newton observatory have now found clues to this missing matter hiding in intergalactic gas.
  • Astronomers have long proposed that there must be intermediate-mass black holes (IMBHs) in space. Now, scientists from the University of New Hampshire have captured the best evidence so far of the existence of these mysterious middleweights, as one emerges from the dark to snack on a star.
  • Like fireworks that linger for millennia, nebulae are some of the most photogenic objects in the universe. These vast clouds of dust and gas represent both the birth and death of stars. New Atlas has collected some of the most breathtaking nebula images ever taken.
  • In August 2017, astronomers observed a collision between two neutron stars so powerful it produced gravitational waves, flares in visible light, radio waves, x-rays and a gamma ray burst. Now that things have quietened, astronomers have studied the strange object created in the cosmic collision.
  • NOAA flew a scientific aircraft right through Hurricane Patricia in 2015. Now, the researchers have reported their findings, including the detection of a beam of antimatter being blasted towards the ground, accompanied by flashes of x-rays and gamma rays.
  • Waiting for water to boil is a minor inconvenience that we’ve all experienced. Maybe next time try the world’s most powerful X-ray laser, which has now been used to boil water to 100,000° C in 75 millionths of a billionth of a second, turning it into a new plasma-like state of matter in the process.

    The dinosaur Archaeopteryx is widely regarded as one of the earliest ancestors of modern birds, but the question of whether or not it could actively fly has been debated for decades. Now, scientists have taken X-ray scans of fossil specimens, and concluded that the answer is yes – sort of.
  • ​Stellar winds thrown out by massive stars behave in surprising ways, according to observations made with the XMM-Newton​ observatory. The colliding winds of large stars actually become brighter, and emit more X-rays, as the matter emitted after a stellar event subsides – contrary to expectations.
