CANBERRA, Australia (AP) — An eruption of Papua New Guinea’s tallest volcano that raised regional tsunami fears subsided Tuesday, but thick ash still billowed into the sky and coated roofs and palm trees nearby.

One of the South Pacific nation’s most active volcanoes, Mount Ulawun erupted on Monday, spewing ash as high as 15 kilometers (50,000 feet).

Papua New Guinea’s Geohazards Management Division said while the eruption had been downgraded since Monday from the maximum alert level, there were no signs that it was ending.

The Polycomb repressive complex 2 (PRC2), initially identified in Drosophila several decades ago, was found to be a key controller of developmental genes. Subsequent research revealed that PRC2 alters chromatin structure to suppress the expression of specific genes.

This initial understanding of PRC2’s ancestral function — functioning primarily to control genes during development — was challenged when it was found to be active in unicellular organisms, in which no development takes place.

Archaeologists from University College Dublin, working with colleagues from Serbia and Slovenia, have uncovered a previously unknown network of massive sites in the heart of Europe that could explain the emergence of the continent’s Bronze Age megaforts—the largest prehistoric constructions seen prior to the Iron Age.

Using satellite images and aerial photography to stitch together the prehistoric landscape of the south Carpathian Basin in Central Europe, the team discovered more than 100 sites belonging to a complex society.

Their commonplace use of defensible enclosures was a precursor and likely influence behind the famous hillforts of Europe, built to protect communities later in the Bronze Age.

Could information be the stuff of which everything is made? Information seems so abstract, not a substance or a thing, so how could it be the building blocks of reality? There are ways and reasons how information can literally be reality, some scientists claim, and their ideas are revolutionary.

This week on Dezeen, Saudi Arabian mega-project Neom revealed its sixth region, Epicon, which will feature a pair of jagged skyscrapers on the Gulf of Aqaba.

Designed by architecture studio 10Design, the project will be distinguished by two steel-clad towers measuring 225 and 275 metres tall. They will be connected by horizontal levels set to contain an outdoor pool and other spaces.

Accommodating 41 hotel and luxury residences, the skyscrapers will be joined by the Epicon resort to form a luxury tourist destination.

What if the song “Baby Shark” stopped after just two stanzas?

For non-fans of the catchy tune, that might sound like a dream. For a real-life Mommy Shark in Illinois, it’s reality: She produced a baby without a Daddy Shark.

The epaulette shark pup hatched this summer at Brookfield Zoo, just west of Chicago. Its mother has been at the zoo since 2019; in that time, she’s never shared a tank with a male.

A dead star is still emitting powerful flares of blue light — a fascinating discovery offering a glimpse into a rare type of star death.

This sounds like game of thrones.
