Shuyu 3D Braincase

419-million-year-old Chinese fossils show human middle ear evolved from fish gills

Leave a Comment / Science / By

Shuyu’s 3D braincase. Credit: IVPP The human middle ear — which houses three small, vibrating bones — is key to transporting sound vibrations to the inner ear, where they become nerve impulses that enable us to hear. Embryonic and fossil evidence proves that the human middle ear evolved from the spiracle of fish. However, the …

Cygnus freighter’s ISS-boosting engine fire ends early

Leave a Comment / Science / By

A planned reboot of the International Space Station (ISS) ended after just 5 seconds for reasons not currently known. Cargo ships docked at the International Space Station regularly fire their thrusters in short bursts to keep the orbiting lab at cruising altitude. Usually these vehicles are Russian Progress capsules, but on Monday (June 20), a …

Blood pressure e-tattoo promises continuous, mobile monitoring

Leave a Comment / Science / By

Credit: University of Texas at Austin Blood pressure is one of the most important indicators of heart health, but it is difficult to measure frequently and reliably outside of a clinical setting. For decades, cuff-based devices that constrict around the arm to provide a reading have been the gold standard. But now, researchers from the …

Astronomers link 64 telescopes to observe the structure of the universe

Leave a Comment / Science / By

Credit: Unsplash/CC0 Public Domain An international team of astronomers has combined the power of 64 radio telescope dishes for the first time to detect the faint signatures of neutral hydrogen gas across cosmological scales. The feat was accomplished using the South Africa-based MeerKAT telescope, a precursor to the world’s largest radio observatory, the SKA Observatory …

Why being hit by space dust is an inevitable aspect of space travel

Leave a Comment / Science / By

On June 8, NASA revealed that its new high-powered space observatory, the James Webb Space Telescope, now shows a small dimple in one of its primary mirrors after being pelted by a larger-than-expected micrometeoroid in deep space. The news came as a shock because the impact occurred in the telescope’s spacecraft just five months ago …

A huge supercluster of galaxies in the early Universe

Leave a Comment / Science / By

A false-color image of the far-infrared emission from a huge protocluster of galaxies (in the circle) dating to the epoch about 1.4 billion years after the Big Bang. Astronomers have made deep optical and infrared observations of the complex and have concluded that the star-forming processes at work, while exceptionally active, generally appear to follow …

Bad Astronomy | Comet 323P/SOHO came too close to the sun and partially disintegrated

Leave a Comment / Science / By

Discovered in 1999, comet 323P/SOHO has an orbit of fire and ice: In its deeply elliptical 4-year orbit around the Sun, it nearly goes out to Jupiter’s orbit, then falls back to just a hair over 5 million miles from the sun’s erratic surface. If you were standing on the comet at that moment, you’d …
