By shooting billions of lasers at the ground, scientists have uncovered evidence of a sophisticated civilization left by the ancient Maya who lived in the northern Yucatán Peninsula in what is now Mexico , a new study finds. The laser survey revealed that in a region of the hilly northern Yucatán, known as the Puuc (pronounced "Pook"), the Maya built remarkable structures, including artificial reservoirs, more than 1,200 ovens, a handful of terraces for farming and nearly 8,000 platforms where houses were built. The ancient Maya also quarried the rock there, the laser scan revealed. "It seems to have been a very prosperous area because we have all these masonry [stone] houses," study lead researcher William Ringle, a professor emeritus of anthropology at Davidson College in North Carolina, told Live Science. "It seems like people had access to what they needed." Moreover, the Maya in the Puuc built four large acropolises dating to the Middle Formative period (700 B.C. … [Read more...] about Details of stunning Maya acropolises and sophisticated civilization revealed by laser scans

Ara Wagoner 23 Oct 2020 0 Source: Ara Wagoner / Android Central 2020 has been the year of the best Chromebooks in more ways than I would have ever imagined back in January: the surge in distance learning and work from home have combined with supply shortages to create an unprecedented demand. As popular models sell out left and right, new models can fill the void and help buyers get a great Chromebook with a much better long-term value. Take the Acer Chromebook Spin 311. Previous generations of the Spin 311 like the CP311-2H are still regularly going for $370 or more on Amazon, so the new CP311-3H launching at $300 with eight years of support ahead of it mean you're getting a sweet deal on a brand new model, so long as the Chromebook holds up in everyday use.

Microsoft today announced that downloadable games on its popular Xbox Live Arcade service will soon be able to offer more Achievement Points—those cross-game digital accomplishment trackers that are great for proving just how much time you've wasted playing Geometry Wars . Starting in April, XBLA game makers will have the option of including 30 Achievements worth up to 400 points in their games, up from current limits of 20 Achievements and 200 points. Starting in June, those new levels will be mandatory for all downloadable games. At first glance, this news would seem to be important only to a particular breed of obsessive Achievement hunter, the kind with a six-digit Gamerscore and a video series explaining how to quickly find new Achievements . But it could also be seen as an effort by Microsoft to increase the apparent value of its downloadable games for a specific subsegment of the audience. When you think about it, Achievement Points are a kind of nontransferable, … [Read more...] about Are we on the cusp of an era of Achievement Point hyperinflation?
Eighty cores is twice the amount you can currently purchase from Intel for up to $8,099, though it’s only a third more than what AMD could sell you for $7,890. But Intel’s flashiest Xeons and AMD’s shiniest Epycs are more similar than you'd imagine; they share the same clock speeds, the same memory options, and the same TDPs. AMD has an upper hand in PCIe connectivity, but Intel’s got better on-chip connectivity, etc. Sapphire Rapids, Intel’s fourth-generation Xeons, share more emerging technologies with GPUs than with other CPUs. Nvidia’s five-figure A100 , for example, is the only GPU to offer up to 80 GB of HBM2e memory. Sapphire Rapids has 64 GB of HBM2e onboard (and eight lanes of DDR5 memory, too). The A100 was the first GPU to support BF16 computation. Sapphire Rapids will support BF16, too. Sapphire Rapids also has PCIe 5.0, a new core architecture called Willow Cove, the 10nm Enhanced SuperFin node, and the new LGA4677-X socket on its resume. All this is public … [Read more...] about A violent delidding reveals that Intel’s Sapphire Rapids CPUs could have up to 80 cores
Genes involved in tasting sweet and savory flavors on the tongue also play a key role in properly working sperm, new research in animals finds. These findings could lead to novel contraceptives for men , and suggest ways to help treat male infertility, the researchers said. In this research, scientists investigated proteins known as taste receptors. These receptors help tongues detect sugars, acids, salt and other chemicals responsible for basic tastes such as sweet, sour, salty, bitter and the savory taste known as umami. Oddly, in the past decade, research has shown taste receptors are also located in other parts of the body, including the stomach, intestines, pancreas, lungs and even the brain. But the functions of these receptors found outside the mouth have remained unclear. To help solve the mystery, researchers focused on receptors that help taste buds detect the sugars and amino acids responsible for sweet and savory tastes. The scientists … [Read more...] about Infertility May Be Linked to Taste Genes
