This workweek in science intelligence , we discovered the almost - complete corpse of a never - before - seen mosasaur that dominated the ancient Pacific Ocean , learned of atom - size bleak fix that could be devouring star from the privileged out , and investigated " no eructation syndrome , " which causes gas and " awkward gurgling . "
The vacation time of year may be in full swing , but the Earth of science news never sleeps — and one of our freehanded stories this workweek was the find of an ancient ocean lusus naturae unlike anything ever learn . The prehistoric predatory animal , which researchers have named " blue tartar , " has an unusual body plan that sets it apart from its extinct relative , and it ’s thought to have wander the Pacific Ocean around 72 million year ago .
Science news this week includes a 72 million-year-old mosasaur unearthed in Japan and a startling theory about atom-size black holes.
Further back in Earth ’s history , about 510 million years ago , the planet underwent a seismal shift that extinguish 45 % of all animals in the ocean . This was the first great extinction , and while the prevailing view has been that this sudden dice - off was caused mainly by the rapid spread of gloomy - O conditions , a new subject area suggests it could have been supercharge by a spate of nauseating chemical substance gas called hydrogen sulphide thatchoked lifetime out of the sea .
In another seismic shift , the vent that had been threatening to break out in Icelandfinally blew in volatile fashion , ending a tenacious hold requiring the evacuation of a whole Ithiel Town , while on the other side of the planet , we exploreda " spectacular " chain of ancient underwater volcanoeson the Antarctic ocean floor .

And in space news , inquiry suggests that particle - size calamitous holes create mere moments after the Big Bang may have been captured by stars — and arenow being forced to eat their style out . We also heard of astrange " glide whistle " fast radio burstthat was picked up by an alien - hunting telescope , see a key ingredient for lifegushing out of Saturn ’s glacial Sun Myung Moon Enceladus , and saw theHubble Space Telescopecapturethe " taboo " lightof a remote spiral coltsfoot .
At the intersection of wellness and technology , we learned howbiased artificial intelligence service could make doctors ' diagnosing less accurateand saw an clever wireless charger that sits under the skin and could one daypower medical devicesbefore unfreeze into the body .
And in the end , dispense with a thought for those who have a rare shape make love as retrograde cricopharyngeus disfunction . Also known as"no burping " syndrome , the uncomfortable ailment leaves the great unwashed unable to burp , thus causing bloating , excessive flatulence and loud gurgling racket in their necks and torsos .
The best of 2023
It was an unbelievable year for science , with more breakthrough and discovery than we could possibly cram into one article — which is why we ’ve made a whole clustering of them . Check out the closing - of - class roundups published so far , and be certain to check back on alive Science for more wondrous science narration .
Picture of the week
dramatic rainbow - colored clouds shimmered in the sky over and around the Arctic for more than three days this calendar week , thanks to an strange cold-blooded shot in the upper ambiance . Even more of these technicolor treats could appear during the next few months , expert say .
The colourful cloud , known aspolar stratospheric clouds , were spotted high in the sky above parts of Norway , Sweden , Finland and Alaska , and even as far south as Scotland . This pic was taken by photographer Ramunė Šapailaitė , who capturedstaggering photos of the rarefied phenomenonabove Gran , in southern Norway .
