Artist’s impression of exocomets orbiting the star ß Pictoris. Credit: © ESO/L. Calçada For the past thirty years, astronomers have been fascinated with the star ß Pictoris because it allows them to observe a young planetary system in the process of formation. It is made up of at least two young planets, as well as … Read more
Scientists at EMBL Barcelona have recapitulated in the laboratory for the first time how the cellular structures that give rise to our spinal column form sequentially. In all vertebrates, the spinal column is the fundamental supporting element of the skeleton. It not only serves as a location for muscles to attach, but it also protects … Read more

During erebosis, fluorescent proteins such as GFP and RFP become lost, making cells “black”. In the beginning of erebosis, cells lose cytoplasmic GFP (left bottom cells). Then, erebotic cells lose nuclear GFP (a cell in the center) and nuclear RFP (a cell at the top center). Credit: RIKEN Researchers have discovered a previously unknown type … Read more
Eyeing some of the components that enabled the Perseverance rover to get safely to the Martian surface could provide valuable insights for future missions. NASA’s Ingenuity Mars Helicopter recently surveyed both the parachute that assisted the agency’s Perseverance rover land on Mars and the cone-shaped backshell that protected the rover in deep space and during … Read more

Specially sourced argon may soon help reveal secrets about the universe’s dark matter. University of Houston Researchers to Create Facility for Mining Exceptionally Pure Argon from Colorado Site A deposit of virtually pure argon that has been left undisturbed since Earth’s formation is about to help physicists learn more about the universe. The Urania Project, … Read more
Are you lacking in energy? Are you sick of feeling tired all the time? Have you been diagnosed with some form of anemia? If you answered any of the previous questions in the affirmative, you should take a supplement and purposely include more iron in your diet. Anemic people require between one hundred and two … Read more
Dying stars’ cocoons may explain fast blue optical transients. In this animation, a cocoon surrounds the jet of a collapsing star. As this cocoon escapes the star, it cools — releasing heat as an FBOT emission. Credit: Ore Gottlieb/Northwestern University First model that is fully consistent with all fast blue optical transient observations. New simulations … Read more
Artist Impression of a superconducting chip. Credit: TU Delft Associate professor Mazhar Ali and his research group at Delft University of Technology (TU Delft) have discovered one-way superconductivity without magnetic fields, something that was thought to be impossible ever since its discovery in 1911 – until now. The discovery, published in the journal Nature, makes … Read more
