Star Discovered Orbiting Milky Way’s Supermassive Black Hole Every 4 Years
Astronomers have discovered a star that orbits the supermassive black hole at the center of our galaxy every four years. That’s the shortest orbit ever observed around a supermassive black hole. The newly discovered star, called S4716, is about four times more massive than our Sun and twice as hot. It survives extraordinary conditions, orbiting…
Scientists discovered novel brain fear mechanisms
There are several different anti-anxiety medications available. Most of them are not considered effective and have unwanted side effects. Identifying mechanisms that underlie fear and anxiety could develop better treatments for anxiety disorders. Neuroscientists from Bristol’s School of Physiology, Pharmacology, and Neuroscience investigated how the brain’s cerebellum influences activity in another brain area called the…
Discovered: An easier way to create ‘flexible diamonds’
Artist's conception showing how guided diamond nanothread synthesis occurs when the starting material is compressed between the points of two diamonds. This diamond anvil cell is a frequently used tool for bringing matter to extreme pressures and Carnegie scientists have been pioneering leaders in deploying this research technique for decades.

Scientists have discovered a long-predicted magnetic state of matter
Almost six decades ago, physicists were interested to know- what happens if making the electronic ‘energy gap’ between an insulator and a conductor smaller and smaller. Will it change a simple insulator into a simple metal where the electrons can move freely, or does something more interesting happen? Physicists predicted that- under certain conditions, it…
Scientists discovered a strange new type of star that has them puzzled
A new study written by German astronomers outlines a new type of star we’ve never seen before. The new hot subdwarf star was discovered by a team of researchers led by Professor Klaus Werner from the University of Tübingen. Scientists believe the new star covered in helium-burning ash is the result of a rare stellar…
Scientists discovered how to trigger apoptosis in leukemia cells
Acute myeloid leukemia (AML) is a hazardous form of cancer. It mainly affects blood and bone marrow cells and can sometimes spread to other body parts. Novel therapeutic approaches for AML are therefore critically needed. A team from the University of Geneva (UNIGE), Switzerland, and Inserm, in France, have identified a previously unknown mechanism that…
In 2010, scientists at the Australian Age of Dinosaurs Museum (QLD) and the University of New England discovered the fossils of crocodiles. Now with ANSTO, scientists performed Advanced nuclear and synchrotron imaging on the fossils. Scientists excavated the fossilized bones of the crocodile – Confractosuchus sauroktonos – from a sheep station near the Winton Formation in Central…
Newly discovered monster galaxy is the largest ever found
Home News (Image credit: Oei, et al/ArXiv) Galaxies are mind-bendingly big structures, but one recently discovered galaxy is an absolute colossus stretching millions of light years across despite having less mass than many of its counterparts.The galaxy in question, Alcyoneus, is a special type of galaxy known as a radio galaxy, defined by a unique…
Astronomers discovered a mysterious spinning mass at the edge of our galaxy
Astronomers have discovered a mysterious repeating transient at the edge of our galaxy. The mass is unlike anything we’ve ever seen, and it releases massive bursts of energy up to three times an hour. Researchers discovered the mass while mapping radio waves in space. The team believes it could be a neutron star or even…
Biologists discovered new information about the tiny propellers on earth
Like bacteria, Archaea are ubiquitous microorganisms that successfully colonize diverse environments. They are found in a vast range of habitats. But there is a slight difference between bacteria and archaea: Archaea don’t cause disease. Archea propels themselves to incredible speeds by rotating a spiral-shaped filament called an archaellum. Scientists at the Unversity of Exeter used…
