Archaeologists have found evidence that in 1650 BCE (Middle Bronze Age), a cosmic airburst destroyed Tall el-Hammam, an ancient walled city in the Jordan Valley close to the north end of the Dead Sea. An eyewitness description of this catastrophic event — which was larger than the 1908 explosion over Tunguska …

AMD has announced a major new efficiency initiative that’s intended to build off its previous 25×20 project. The company will now work to deliver a 30x improvement in energy efficiency in AI and high performance computing overall, relative to today’s CPU and GPU accelerators. AMD’s blog post doesn’t go into …

The isotope tin-100 is of interest for nuclear structure due to its closed-shell proton and neutron configurations. It is also the heaviest nucleus comprising protons and neutrons in equal numbers. In new research, physicists from the ISOLTRAP experiment at CERN’s Isotope mass Separator On-Line (ISOLDE) facility performed direct mass measurements …

As early as 18,000 years ago, early foragers in the montane rainforests of New Guinea preferentially collected eggs of cassowaries (Casuarius sp.) in late stages of embryonic growth and may have hatched them to rear chicks, according to an analysis of ancient eggshells from two Late Pleistocene/Early Holocene rock shelter …

A new genus and species of extinct predatory bird has been identified from a fossilized partial skeleton unearthed in South Australia. Life reconstruction of Archaehierax sylvestris.

Processings…Please wait. Opinions expressed in this article are those of the sponsor. Data remains one of the most powerful assets in business. Those who know how to leverage it can execute data-driven campaigns with purpose, precision, and laser vision. And those who don’t are likely to have rudderless marketing campaigns …

Using machine learning, a team of physicists at Lawrence Livermore National Laboratory has studied the phase behaviors of superionic water — a phase of water where hydrogen atoms become liquid-like while oxygen atoms remain solid-like on a crystalline lattice — with unprecedented resolution. Hydrogen atoms diffuse easily between the superionic …

(Photo:Annie Spratt/Unsplash)Big-name tech manufacturers are again facing delays, but this time the pandemic isn’t to blame. Commitments to reduce energy consumption and a widespread coal shortage have resulted in some Chinese Apple and Tesla suppliers slowing production and even shutting down for days at a time. China announced in April …

The newly-discovered dinosaur species, Spicomellus afer, is the earliest-known ankylosaur and the first ankylosaur to be named from Africa. Life reconstruction of the armored dinosaur Borealopelta markmitchelli, which lived in what is now Alberta, Canada, some 110 million years ago, eating ferns.

If the 21st century has taught us any astronomical lessons, it’s that counting planets is hard. In 2000, there were nine planets, and now there are eight, but that might not last. Astronomers have been on the hunt for a theorized ninth planet in the extreme outer solar system, and …
