Researchers have discovered what they say is the world’s oldest intact shipwreck at the bottom of the Black Sea. Until now, the ship had only been seen on pottery.

This Hubble image captures the unbarred spiral galaxy NGC 5033, a Seyfert galaxy that looks a lot like our Milky Way.
A dazzling photo captured by the Hubble Space Telescope showcases the glowing heart of a relatively close spiral galaxy — fairly similar to our Milky Way.
Unveiled on October 22 by the Hubble Space Telescope website, the snapshot offers a close portrait of a galaxy called NGC 5033 — a spiral galaxy nestled some 40 million light-years away from Earth, in the Canes Venatici constellation — also known as the Hunting Dogs.
A future ‘quantum internet’ could find use long before it reaches technological maturity, a team of physicists predicts.
Such a network, which exploits the unique effects of quantum physics, would be fundamentally different to the classical Internet we use today, and research groups worldwide are already working on its early stages of development. The first stages promise virtually unbreakable privacy and security in communications; a more mature network could include a range of applications for science and beyond that aren’t possible with classical systems, including quantum sensors that can detect gravitational waves.
Scientists believe they’ve discovered a new method to pin down just how fast our universe is expanding over time.
In a new study, a team of researchers from the University of Chicago found that studying the gravitational waves emitted by cosmic collisions could lead to more resolute predictions about how quickly the universe is expanding.
Wow that’s futuristic lvl streamlining…
Apple has today filed a patent for a set of intriguing new autonomous vehicle features called “Peloton.” The filing describes the ability for multiple self-driving cars to share battery capacity via a “connector arm,” dynamically adjust positions, increase efficiency, and more.
MANILA, Philippines — A mobile and SMS application developed by IT professionals Revbrain G. Martin, Marie Jeddah Legaspi, and Julius Czar Torreda to help fishermen receive real-time weather, sunrise and sunset, wind speed, and cloud coverage to plan their fishing activity, and an emergency checklist kit app was developed by students Jeorge Loui P. Delfin, Bluen Ginez, Samuel Jose, Rainier Garcia Narboneta, and Eugenio Emmanuel A. Araullo for disaster preparedness won the NASA Space Apps Challenge on October 19–21 at De La Salle University in Manila, Philippines, in partnership with the Embassy of the United States of America and PLDT.
Other projects and solutions developed are games using images from the Hubble Space Telescope, augmented reality mobile app to tell a story of the changes in the Arctic and Antarctic ice, artificial intelligence app helping scientists confirm the habitability of exoplanets, and story-based game using NASA Earth imagery.
They joined together with teams of coders, scientists, designers, storytellers, makers, builders, technologists, thinkers, designers, entrepreneurs, and everyone around the globe working together in a 48-hour sprint to develop solutions to some of the most pressing challenges on Earth and in space, using NASA resources and data.
Protein Chrdl1 appears to regulate brain plasticity.
Researchers from the Salk Institute have discovered that a protein called Chrdl1, secreted by astrocytes, is responsible for driving synapse maturation and limiting brain plasticity later in life [1].
Abstract
In the developing brain, immature synapses contain calcium-permeable AMPA glutamate receptors (AMPARs) that are subsequently replaced with GluA2-containing calcium-impermeable AMPARs as synapses stabilize and mature. Here, we show that this essential switch in AMPARs and neuronal synapse maturation is regulated by astrocytes. Using biochemical fractionation of astrocyte-secreted proteins and mass spectrometry, we identified that astrocyte-secreted chordin-like 1 (Chrdl1) is necessary and sufficient to induce mature GluA2-containing synapses to form. This function of Chrdl1 is independent of its role as an antagonist of bone morphogenetic proteins (BMPs). Chrdl1 expression is restricted to cortical astrocytes in vivo, peaking at the time of the AMPAR switch. Chrdl1 knockout (KO) mice display reduced synaptic GluA2 AMPARs, altered kinetics of synaptic events, and enhanced remodeling in an in vivo plasticity assay.
