We summarize the week's scientific breakthroughs every Thursday.
- 			 Chemistry ChemistryThis weird chemical bond acts like a mash-up of hydrogen and covalent bondsChemistry students are taught that hydrogen bonds and covalent bonds are distinct, but a new study shows they exist on a continuum. 
- 			 Astronomy AstronomyEnormous X-ray bubbles balloon from the center of the Milky WayImages from the the eROSITA telescope reveal X-ray–emitting blobs surrounding gamma-ray bubbles. 
- 			 Quantum Physics Quantum PhysicsThe new light-based quantum computer Jiuzhang has achieved quantum supremacyA second type of quantum computer has now performed a calculation impossible for a traditional computer. 
- 			 Physics PhysicsNewton’s groundbreaking Principia may have been more popular than previously thoughtA search has uncovered over 300 copies of Isaac Newton’s famous 17th century book, the Principia, revealing a broader readership than assumed. 
- 			 Physics PhysicsSupercooled water has been caught morphing between two formsA new experiment used ultrafast techniques to reveal high-density water transforming into low-density water at subfreezing temperatures. 
- 			 Physics PhysicsGiant lasers help re-create supernovas’ explosive, mysterious physicsFor the first time, scientists have re-created a type of shock wave that occurs in supernovas. 
- 			 Earth EarthSTEVE may be even less like typical auroras than scientists thoughtThe purple-and-green, atmospheric light show nicknamed STEVE just got even stranger. 
- 			 Physics PhysicsLIGO and Virgo’s gravitational wave tally more than quadrupled in six monthsScientists report 39 sets of spacetime ripples from just half a year of data. 
- 			 Quantum Physics Quantum PhysicsGalileo’s famous gravity experiment holds up, even with individual atomsWhen dropped, two types of atoms accelerate at the same rate despite their differences, much like objects in Galileo’s leaning Tower of Pisa experiment. 
- 			 Physics PhysicsA photon’s journey through a hydrogen molecule is the shortest event ever timedThe shortest duration ever measured is 247 zeptoseconds, or trillionths of a billionth of a second. 
- 			 Animals AnimalsThe diabolical ironclad beetle can survive getting run over by a car. Here’s howThe diabolical ironclad beetle is an incredibly tough little creature. A peek inside its exoskeleton reveals what makes it virtually uncrushable. 
- 			 Physics PhysicsThe first room-temperature superconductor has finally been foundA compound of carbon, hydrogen and sulfur conducts electricity without resistance up to 15° C, but there’s a catch: It works only under high pressure.
