Mineral body armor protects some leaf-cutting ants in battle

Leaf-cutting worker ants might look like they’d be helpless against an enemy soldier ant many times their size. But some of the smaller ants have a secret: Their entire body is coated with a thin but tough layer of mineral armor.

It’s the first time that this type of external, whole-body mineralization has been found in an adult insect, researchers report online November 24 in Nature Communications.

“I found rock ants,” evolutionary biologist Hongjie Li recalls telling his colleague, evolutionary biologist Cameron Currie, when the first experimental results of the hard coating came in. “I can still feel the excitement now,” Li says.

The discovery was serendipitous, says Currie, of the University of Wisconsin–Madison, who has been studying leaf-cutting ants for more than 20 years. His lab had been examining interactions between ants and their external microbes, which are thought to play a pivotal role in the ants’ farming

One-of-a-kind fossil shows T. rex and Triceratops locked in battle to the death

When you imagine dinosaurs battling it out, the first match-up that comes to mind is Triceratops vs. T. rex. In our collective imagination they are fighting eternally. It’s the clash of the titans. But did these battles actually take place?

Yes. Yes they did. We have the fossil to prove it, and for the first time ever, the public will be able to take a look.

The fossil — nicknamed “Dueling Dinosaurs” — was initially discovered in 2006, but until now has only been seen by a select few.

The pair are preserved in a fossil going on display for the first time at the North Carolina Museum of Natural Sciences, The

EU auditors see uphill battle for EU antitrust regulators versus big tech

BRUSSELS (Reuters) – EU antitrust enforcers face an uphill battle in tackling tech giants abusing their dominance because of the difficulty of finding remedies, the EU’s budget watchdog said on Thursday in its first audit of the regulators.

The report by the European Court of Auditors comes as critics of Google GOOGL.O voiced frustration at what they say is ineffective enforcement of a series of EU rulings ordering it to stop favouring its own online services to the disadvantage of competitors.

Besides Google, European Competition Commissioner Margrethe Vestager is also investigating Amazon AMZN.O, Apple AAPL.O and Facebook FB.O.

“Although the Commission has taken a number of case decisions tackling challenges resulting from the digital economy, significant challenges remain to be resolved,” the watchdog said.

“For example, practices in digital markets can cause damage to consumers. However, it is difficult for the Commission to find appropriate remedies to tackle

Battlepalooza is the first battle royale to use Google Maps for levels

The autumn wind may be a Raider, but fans of Las Vegas’s NFL team haven’t had a real chance to pillage The Strip as part of their football fun thanks to COVID-19. But if they’re battle royale players, they’ll soon get to fight in Vegas with a new game that uses Google Maps to turn places like San Francisco and the Sin City into battlegrounds.

Today, nWay is announcing Battlepalooza, a mobile battle royale game. It launches December 10 for iOS and Android. Now, battle royale ain’t nothing new, be it on mobile, console, or PC. But Google confirms nWay is the first studio to use the Maps platform to put cities into one of these games. The two worked together to develop Battlepalooza.

Battle royale continues to be a strong segment of the mobile gaming market. According to estimates from research firm Sensor Tower, the top 25 battle royale

It may have been a battle for the ages in ancient Montana.

About 67 million years ago, two iconic dinosaurs, a Triceratops horridus and a Tyrannosaurus rex, died and were quickly buried together side by side in a single grave. And both of them bear battle scars. It’s the kind of showdown scientists have speculated about for years, but it has only ever appeared in “Jurassic Park” games — until now.

The impressively complete skeletons of these “dueling dinosaurs” will go on display and be studied at the North Carolina Museum of Natural Sciences in 2022, the museum announced Tuesday. The museum is located in downtown Raleigh.

The fossil of the Triceratops was first discovered 2006 as it eroded out of sedimentary rock from the Hell Creek Formation. This rock formation, which dates to 65.5 million years ago, was named for

Pandorabots’ Bot Battle highlights lack of industrywide metrics for open domain AI

Emerging technology fields need industrywide metrics to measure progress. So a pun-loving chatbot startup called Pandorabots decided to put on a flashy Bot Battle. The Bot Battle consisted of two virtual beings chatting 24 hours a day, seven days a week for two weeks (unlike humans, AIs never tire). Viewers were invited to vote on the better chatbot.

The first contestant, “Mark Zuckerb0rg,” is based on Facebook’s Blenderbot. He’s a terse figure who wears a “Make Facebook Great Again” hat and doesn’t shy away from intolerant opinions like “I don’t like feminists.” The Pandorabots chatbot Kuki is arguably more eloquent. But she’s a politician, often taking the conversation back to her comfort zone and delivering the same quips again and again. The winner? Kuki, with 79% of the votes and 40,000 views. But Pandorabots says the real aim of the Bot Battle is to spark an industrywide conversation about the

Are PS5 Consoles In Short Supply? Gamers Face Battle Buying Sony’s New System

KEY POINTS

  • Retailers such as Target are out of stock
  • The system goes for $499, but is $100 cheaper for a digital-only package
  • Sony didn’t stock shore shelves with PS5s because of the pandemic

Gamers on Thursday got their chance to snatch up the latest iteration from PlayStation but supply-chain issues and the pandemic are making it tough to buy.

Sony announced last week its PlayStation5 would be available to the general public on Nov. 12, and a week later in some regions — just not in stores. Pre-orders were available and some Twitter users suggested they were walking out of stores under the watchful eye of the unfortunate.

“What a year,” Jim Ryan, the president and CEO of Sony Interactive Entertainment, said in a statement Wednesday.

In announcing the launch plans last week, the company said that in the interest of keeping people safe during the pandemic, sales would

AI and the Battle for the Future of Photo Editing

For photographers, AI photo editing is no longer a fringe topic for ML researchers or a gimmick employed by smartphone apps. With the impending release of Skylum’s Luminar AI and Adobe calling the latest build of Photoshop “the world’s most advanced AI application for creatives,” it’s time for the community to reckon with an important question: What does this mean for photography, photo editing, and creativity at large?

One of the hottest hot takes in the industry right now is that AI photo editing is going to be very bad for photographers and retouchers of all stripes. Whether it’s Luminar AI, Adobe’s Sensei AI-powered tools, or the NVIDIA technology behind Photoshop’s new portrait editing features, most photographers seem wary of this technology and its potential impacts of creativity.

Naysayers paint a grim picture of over-edited portraits and homogenous landscapes that are indistinguishable from one another–each of them edited using the
