Researchers using ALMA

The Atacama Large Millimeter/submillimeter Array (ALMA) is the largest ground-based facility for observations in the millimeter/submillimeter regime in the world. ALMA comprises 66 high-precision dish antennas of measuring either 12 meters across or 7 meters across and spread over distances of up to 16 kilometers. It is an international partnership between Europe, the United States, Japan, and the Republic of Chile.

Former Xerox CEO Ursula Burns says she balanced work and family by “outsourcing the caring for my kids.” Here’s what that means, and how it panned out for her.

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.
