Untangling what happened in our Solar System tens or hundreds of millions of years ago is challenging. Millions of objects of wildly different masses interacted for billions of years, seeking natural stability. But its history—including the migration of the giant planets—explains what we see today in our Solar System and maybe in other, distant solar … Read more
Credit: Pixabay/CC0 Public Domain An international collaborative research team, including scientists from UQ’s Queensland Brain Institute (QBI), has discovered a novel mechanism underlying memory involving rapid changes in a specific DNA structure. The team found that G-quadraplex DNA (G4-DNA) accumulates in neurons and dynamically controls the activation and repression of genes underlying long-term memory formation. … Read more
NASA launched Juno, the solar-powered spacecraft back in 2011. It took about six years for Juno to cruise over to Jupiter. Juno looks like a propeller that’s been orbiting around our solar system’s biggest planet for about eight years now. It has captured some stunning images and collected groundbreaking data. Now, Juno has cruised over … Read more
Astronomers have discovered a black hole with a mass about 33 times greater than that of our sun, the biggest one known in the Milky Way aside from the supermassive black hole lurking at the center of our galaxy. The newly identified black hole is located about 2,000 light-years from Earth – relatively close in cosmic terms – in the constellation Aquila, … Read more

Researchers from Miguel Hernández University of Elche (UMH) have conducted a vegetation analysis over the last 30 years using satellite images from two environments in the Sierra de Cazorla Natural Park (southeast Spain)—one with wild ungulates such as deer and the … Read more
LONDON — Japan is on track to beam solar power from space to Earth next year, two years after a similar feat was achieved by U.S. engineers. The development marks an important step toward a possible space-based solar power station that could help wean the world off fossil fuels amid the intensifying battle against climate … Read more

Radio sky in the 30 MHz–43 MHz (left) and 47 MHz–78 MHz bands (right); zenith is at the center of the images. Strong sources are labeled, notably including Jupiter and the Sun. In the lower frequency image, Jupiter is of comparable brightness to the Sun, illustrating that the starplanet intensity ratio can be of order … Read more
A newly discovered 98-foot-long dinosaur named after the Hindu god Shiva “The Destroyer” stomped around Argentina alongside other long-necked “megatitanosaurs” more than 90 million years ago, scientists reveal. Researchers described the humongous beast, called Bustingorrytitan shiva, late last year from fossils discovered in western Argentina. Now, they’ve worked with an artist to recreate the Cretaceous … Read more
Optical coherence tomography. Credit: LaNCE-Neuropharm—GIC 21/133 Although there are still some aspects pending confirmation for its use in the clinical setting, and its resolution needs to be improved slightly, a study by the UPV/EHU and Biobizkaia has shown that a method routinely used to carry out ophthalmological tests can also be used to monitor the … Read more
