Mummified parrots point to trade in the ancient Atacama desert

Ancient Egyptians mummified cats, dogs, ibises and other animals, but closer to home in the South American Atacama desert, parrot mummies reveal that between 1100 and 1450 CE, trade from other areas brought parrots and macaws to oasis communities, according to an international and interdisciplinary team.

Early Universe explosion sheds light on elusive black hole

Scientists discover one of the first black holes of its kind. Intermediate mass black holes (100 to 100,000 times the mass of the sun) have only been directly detected once before (LIGO, last year). They form an important link between the smaller black holes left behind after the deaths of stars, and the supermassive black holes which lurk in the hearts of every galaxy. The astrophysicists also find that there are about 40,000 of these objects in the neighbourhood of our galaxy.

String theory solves mystery about how particles behave outside a black hole photon sphere

A new article explores the string theoretical effects outside the black hole photon sphere.

Researchers have succeeded in imaging so-called surface phonons in three dimensions for the first time. The research success could accelerate the development of new, efficient nanotechnologies.

First steps towards revolutionary ULTRARAM™ memory chips

A new type of universal computer memory - ULTRARAM™ - has taken a step closer towards development with a successful experiment. 'Universal memory' is a memory where the data is robustly stored, but can also easily be changed; something that was widely considered to be unachievable until now. The new non-volatile RAM, called ULTRARAM™, is a working implementation of so-called 'universal memory', promising all the advantages of DRAM and flash, with none of the drawbacks.

Stellar eggs near galactic center hatching into baby stars

Astronomers found a number of stellar eggs containing baby stars around the center of the Milky Way using the Atacama Large Millimeter/submillimeter Array (ALMA). Previous studies had suggested that the environment there is too harsh to form stars. These findings indicate that star formation is more resilient than researchers thought.

Scientists discover a new auroral feature on Jupiter

Astronomers have detected new faint aurora features, characterized by ring-like emissions, which expand rapidly over time. Scientists determined that charged particles coming from the edge of Jupiter's massive magnetosphere triggered these auroral emissions.
