When a star explodes in a supernova, it sometimes leaves a remnant that has a ring shape, such as seen here in this illustration of SN 1987A. Credit: NASA/CXC/A. HobartWestern Sydney University researchers, together with an international team of experts, have discovered a mysterious circular ring near our neighboring galaxy that could be the first known case of an intergalactic Supernova Remnant – remains of an exploded star that could be up to 7,000 years old.Dubbed a ‘rogue’ Supernova Remnant by the scientists and named…

Astronomers have uncovered a star, called HD 222925, that has the widest range of elements yet observed in a star beyond our own Sun. They have identified 65 elements in the star, including 42 from the bottom of the periodic table.A team of astronomers led by University of Michigan’s Ian Roederer and including Carnegie’s Erika Holmbeck have identified the widest range of elements yet observed in a star beyond our own Sun. Their findings will be published in The Astrophysical Journal Supplement Series.The researchers…

Spider-Man fans have been left stunned by the name of an obscure villain from the Marvel comic book series.While many of Spider-Man’s nemeses are almost as well-known as he is – such as Doctor Octopus, Venom or Green Goblin – the minor fellon known as Spectrum has perhaps the most famous name of all.As was recently pointed out in a viral tweet, Spectrum’s real name is in fact Joe Biden.The character first appeared in Peter Parker No 1 back in 2010, at a time when the real-life Joe Biden was serving as US Vice President…

Netflix is adding a new feature called the “Category Hub” in the TV menu that allows viewers to find their favourite content more easily. The latest hub will be displayed on the left-hand menu of kids' and adults' profiles and lets subscribers find their favourite genres and discover new categories of movies. Subscribers of the streaming platform will be able to see the top three category recommendations tailored to their viewing habits. It will also include curated collections based on holidays. Netflix recently…

Researchers uncover critical changes in the thermal properties of energy storage devices during operation, paving the way towards better thermal management.Modern energy storage devices, such as supercapacitors and batteries, have highly temperature-dependent performance. If a device gets too hot, it becomes susceptible to ‘thermal runaway.’ Thermal runaway—or uncontrolled overheating—can ultimately result in dangerous explosions or fires. Adopting a well-informed thermal management strategy is required for the stable and…

TikTok has a number of ways for its users to discover new content. And it looks like the wildly popular short-form video sharing app is switching up how it recommends which bite-sized videos you should watch next. And it’s doing so with a more personal touch. On Thursday, TikTok tweeted that it would continue rolling out a new Friends tab which will feature posts from “people you’re connected with.” And based on the picture shared in the tweet, it looks like the Friends tab will also replace what’s currently known as…

A new discovery deep beneath one of Antarctica's rivers of ice could change scientists' understanding of how the ice flows, with important implications for estimating future sea level rise. Glacier scientists Matthew Siegfried from Colorado School of Mines, Chloe…

A region of the mouse brain, called the bed nucleus of the stria terminalis, is larger in males than females. Many neurons (green) produce the estrogen receptor. A specific population of these neurons (labeled for a protein called Nfix in red) is more abundant in males than in females. CSHL Assistant Professor Jessica Tollkuhn and her team identified genes targeted by estrogen in neurons that coordinate sex differences in neural circuits.
