The galaxy, named R5519, is 11 billion light-years from our Solar System and it is making stars at a rate 50 times greater than the Milky Way. The hole at its centre is truly massive, with a diameter two billion times longer than the distance between the Earth and the Sun.

That means it is three million times bigger than the diameter of the supermassive black hole in the galaxy Messier 87, which in 2019 became the first ever to be directly imaged.

Astronomers have captured an image of this "cosmic ring of fire" as it existed 11 billion years ago. It was roughly the mass of the Milky Way, is circular with a hole in the middle, rather like a titanic doughnut.

There is a rare condition in humans and other vertebrates where they genetically belong to one sex but also have characteristics of the other.

Decades ago, scientists found that Oryzias latipes (Japanese rice fish, also called medaka) often undergo sex reversal in the wild and new exploratory research may lead to insight in humans.

In medaka fish. sex reversal involves genetically female larvae (meaning they have two X chromosomes) going on to develop male characteristics, or vice versa. Scientists had already discovered that environmental factors, such as temperature changes in the brackish and fresh waters where medaka fish live, are likely involved in their sex reversal.
A year ago, and for this entire century, the nexus of anti-vaccine beliefs and other denial of science has been Democratic states. While places like Mississippi and Alabama had vaccine rates near 100 percent, an infectious disease crisis that began on the west coast forced politicians in California, where kids without vaccines totaled more than the other 49 states combined, to shuck off their wealthiest constituents and mandate them.

Then COVID-19 took the world by storm and  all of that changed.

Because Australia was discovered late by Europeans it is considered an old continent with little geological activity, but a new study reveals that its mountains are still growing. Some parts of the Eastern Highlands of Victoria, including popular skiing destinations such as Mt Baw Baw and Mt Buller, may be as young as 5 million years, not the 90 million years thought by many.

The findings result from speleothems - stalagmites, stalactites, and flowstones - in the Buchan Caves.
 Isotope analysis, ancient pathogen genomics, plus a dash of human population genetics have revealed the deeper connection to date between the early peoples of Siberia and the Americas. 

During the Early Bronze Age, people were expanding. 
Using light waves to accelerate supercurrents can discern forbidden light the quantum world, where the conventional laws of physics are already forbidden.

Supercurrents are scientifically strange. At super cold temperatures, they can give us electricity that moves through materials without resistance and use of light pulses at terahertz frequencies- trillions of pulses per second - to accelerate electron pairs, known as Cooper pairs, within supercurrents, led scientists to "second harmonic light emissions," or light at twice the frequency of the incoming light used to accelerate electrons.
Why is Homo neanderthalensis gone while Homo sapiens have bent the world to our will? 

In recent years, there has been speculation that climate change wiped out Neanderthal people, or interbreeding with us, since many of us have DNA shared by Neanderthals (we also share 60 percent of our DNA with a banana) but a new paper affirms the earliest belief about survival of the fitter, commonly called survival of the fittest; competition between Cro-Magnon and Neanderthal. And Neanderthals lost.
Satellite data with on-the-ground observations over two summers in Antarctica to detect and measure the green snow algae have led a group of scientists to suggest that if the world warms, larger fields of bright green snow could be seen from space as it spreads.

Antarctica is the world's southernmost continent, typically known as a frozen land of snow and ice. But terrestrial life can be abundant, particularly along its coastline. Although each individual alga is microscopic in size, when they grow en masse they turn the snow bright green.
