Geology is a big science. The Earth is a large enough place today, but when you stretch the fourth dimension back across many millions of years, the largeness can get out of hand. Because we lose a lot of detail to the ravages of time, it's very difficult for geology to get small again—to tell us about what happened in individual locations or over short periods of time.
So it's not every day that you read a scientific paper titled "The first day of the Cenozoic." The Cenozoic is the name geologists give to the era spanning the last 66 million years, and it started with the mass extinction event that killed off (most of) the dinosaurs. There were incredible eruptions that contributed to the extinction event and spanned a considerable amount of time.
But the asteroid that struck off the coast of what is the Yucatán Peninsula today was the opposite—it couldn't have been much more sudden. A recent drilling project recovered a long core of rock from the Chicxulub impact crater, leading to greater clarity about how the calamity played out—including on that first day.
In January 1997, the crew of a fishing vessel in the Baltic Sea found something unusual in their nets: a greasy yellowish-brown lump of clay-like material. They pulled it out, placed it on deck and returned to processing their catch. The next day, the crew fell ill with serious skin burns. Four were hospitalized. The greasy lump was a substance called yperite, better known as sulfur mustard or mustard gas, solidified by the temperature on the sea bed.
At the end of the World War II, the US, British, French and Soviet authorities faced a big problem—how to get rid of some 300,000 tonnes of chemical munitions recovered from occupied Germany. Often, they opted for what seemed the safest, cheapest and easiest method: dumping the stuff out at sea.
Legal wrangling among the federal government, the state of California, and four automakers who—oddly—are asking for more stringent regulations got even more knotty this month, when the Department of Justice reportedly launched an antitrust probe into companies that struck a deal with California climate regulators.
Now some members of Congress are urging an independent investigation of the investigation, amid suspicions that the probe is an attempt to punish the automakers—and California—for parting ways with federal policy on fuel economy.
The “what’ is confusing; the “why,” less so. If the average global temperature rises by 4°C by the end of the century, as it may be on track to do, scientists say a whole bunch of bad things would likely happen: higher sea levels, more extreme weather. In the US, transportation is responsible for 29% of greenhouse gas emissions, and nearly 60% of those come from light-duty vehicles like passenger cars.

The following excerpt comes from Arcade Perfect: How Pac-Man, Mortal Kombat, and Other Coin-Op Classics Invaded the Living Room by David L. Craddock.
Sickly green light washed over the stubble and pale complexion of the man hunched in front of his computer monitor. Beside it sat a television, black except for five horizontal, crimson-colored bands running from top to bottom like lines on notebook paper.
Garry Kitchen closed his eyes, but the straight red lines were burned into the backs of his eyelids. Behind him came a steady pounding: pound—pound-pound-pound. He didn’t rise to the bait. He knew what he’d see. On the arcade cabinet’s screen, a giant ape the size of King Kong had just scaled a construction site made of straight red girders. With every stomp, the platforms had twisted and bent until they were slanted like ramps. Standing tall at the top, the ape intoned his grating, mechanical laugh.
Scientists want to rip the Universe apart. At least that is what a Daily Mail headline might read. Lasers can now reach power in the petawatt range. And, when you focus a laser beam that powerful, nothing survives: all matter is shredded, leaving only electrons and nuclei.
But laser physicists haven’t stopped there. Under good experimental conditions, the very fabric of space and time are torn asunder, testing quantum electrodynamics to destruction. And a new mirror may be all we need to get there.
On average, the amount of power used by humans is about 18 terawatts. A petawatt is 1,000 times larger than a terawatt. The baddest laser on the planet (currently) produces somewhere between 5 and 10 petawatts, and there are plans on the drawing board to reach 100 petawatts in the near future. The trick is that the power is not available all the time. Each of these lasers produces somewhere between 5-5000 J of energy for a very very short time (between a picosecond—10-12s—and a few femtoseconds—10-15s). During that instant, however, the power flow is immense.
For nearly three years, the December 2016 cyberattack on the Ukrainian power grid has presented a menacing puzzle. Two days before Christmas that year, Russian hackers planted a unique specimen of malware in the network of Ukraine's national grid operator, Ukrenergo. Just before midnight, they used it to open every circuit breaker in a transmission station north of Kyiv. The result was one of the most dramatic attacks in Russia's years-long cyberwar against its western neighbor, an unprecedented, automated blackout across a broad swath of Ukraine's capital.
But an hour later, Ukrenergo's operators were able to simply switch the power back on again. Which raised the question: Why would Russia's hackers build a sophisticated cyberweapon and plant it in the heart of a nation's power grid only to trigger a one-hour blackout?
A new theory offers a potential answer. Researchers at the industrial-control system cybersecurity firm Dragos have reconstructed a timeline of the 2016 blackout attack [PDF] based on a reexamination of the malware’s code and network logs pulled from Ukrenergo’s systems. They say that hackers intended not merely to cause a short-lived disruption of the Ukrainian grid but to inflict lasting damage that could have led to power outages for weeks or even months. That distinction would make the blackout malware one of only three pieces of code ever spotted in the wild aimed at not just disrupting physical equipment but destroying it, as Stuxnet did in Iran in 2009 and 2010 and as the malware Triton was designed to do in a Saudi Arabian oil refinery in 2017.

Android developer site xda-developers got its hands on a pre-release copy of the Camera app designed for Google's upcoming Pixel 4—so naturally, the site then sideloaded it on a Pixel 2XL.
The majority of the settings exposed in the screenshots already existed in Camera 6.x, but even long-time Pixel users could be forgiven for not knowing they existed. Where Camera 6.x hid them in five separate menus—each squirreled away behind a tiny, unintuitive icon at the top of the viewfinder—Camera 7.0 combines them into a single, much easier-to-read menu. This one context-sensitive settings menu (its options differ between, for example, Night Sight mode and regular Camera mode) can be accessed either by tapping a drop-down arrow or by swiping down on the viewfinder itself.
Behind the scenes, xda-developers reports finding new scene-detection code that integrates with an extended "Camera coaching" feature that offers tips for taking better pictures. If you're sick and tired of seeing "try Night Sight mode" or "try Portrait mode" popping helpfully up while taking pictures, you'll also be able to disable the feature entirely—whereas, at least so far as we can tell, in Camera 6.x you're stuck with them.
The Trump administration is sanctioning three North Korean hacking groups widely accused of carrying out attacks that targeted critical infrastructure and stole millions of dollars from banks in cryptocurrency exchanges, in part so the country could finance its weapons and missiles programs.
All three of the groups are controlled by North Korea’s primary intelligence agency, the Reconnaissance General Bureau, or RGB, officials with the US Department of Treasury said in a statement published on Friday. Collectively, the groups are behind a host of cyber attacks designed to spy on adversaries and generate revenue for nuclear weapons and ballistic missile programs.
“Treasury is taking action against North Korean hacking groups that have been perpetrating cyber attacks to support illicit weapon and missile programs,” Sigal Mandelker, Treasury under-secretary for terrorism and financial intelligence, said in Friday’s statement. “We will continue to enforce existing US and UN sanctions against North Korea and work with the international community to improve cybersecurity of financial networks.”
The Centers for Disease Control and Prevention has updated and revised the national tally of illnesses linked to the use of e-cigarettes, aka vaping, dropping the count from 450 possible cases to 380 confirmed and probable cases, the agency announced late Thursday.
The new figure follows a clearer clinical definition for the illness as well as further investigation into individual cases. The 380 confirmed and probable cases now span 36 states and still include six deaths, as reported earlier. The CDC added that the current number of cases “is expected to increase as additional cases are classified.”
While health investigators are clearing the air around the clinical aspect of the cases, the cause is still foggy. Though all the cases are associated with vaping, investigators have struggled to identify specific vape products or ingredients that tie all the cases and symptoms together.

Verizon says it will bring its "5G Home" Internet service to every market where it deploys 5G mobile service.
That might not be saying much, given how limited Verizon's early 5G deployments are. But it would mean that at least some people in each 5G mobile market would be able to buy the 5G fixed Internet service, which offers an alternative to wired Internet.
"You should expect that every market that opens a 5G mobility market will in due course be a 5G fixed wireless [market] because it is one network," Verizon Consumer Group CEO Ronan Dunne said Wednesday at an investor conference (link to webcast and transcript).
FRANKFURT, GERMANY—The cars we drive are increasingly defined as much by the software they run as their engines or chassis. It started slowly. Discrete electronic control units started to appear under the hood, controlling fuel management or anti-lock brakes. New functions required new code, run on new little black boxes, metastasizing to the point where today, a new car might have up to 70 different modules, with software from as many as 200 different vendors. If that sounds like a recipe for disaster, it can be. Which is why Volkswagen Group—parent company to brands like VW, Audi, and Porsche—is saying "enough!"Internal competition versus economies of scale
"Software is extremely complex nowadays. Each function is connected with everything—in the car, in the cloud, with the dealers—and we see that too many projects are in too much trouble. The process chain is not stable anymore; there's so much inefficiency to this process," explained Christian Senger, who is responsible for VW Group's Digital Car and Services division. The problem is partly one by design; Ferdinand Piech specifically wanted Audi, Porsche, and Volkswagen to each develop software independently, the idea being that internal competition could improve the breed.
But it has led to balkanization. "Today, we build more than 10 million cars a year. But they are running on roughly eight different electronic architectures. In mechanical engineering, I would call us a platform champion," Senger said, referring to VW Group's strength in using a small number of common architectures—MQB for transverse-engined vehicles, MLB Evo for premium models, and now MEB for smaller electric vehicles—across multiple brands. "We defined how global industrialization of brands and markets really works. In software, there is no reason for having eight different architectures," he said, contrasting VW Group's current situation with the Android OS, where the same software runs on $60 smartphones as well as $1,000 smartphones.
Hot on the heels of this summer's adaptation of Scary Stories To Tell in the Dark, Nickelodeon has dropped the first trailer for its reboot of the popular 1990s series, Are You Afraid of the Dark?, featuring a group of teens telling each other scary campfire stories that then come to life.
The original Are You Afraid of the Dark? was a Canadian "dark fantasy" (aka YA horror) anthology series that aired on Nickelodeon in the US from 1990 to 1996, followed by a second run from 1999 to 2000. At the start of each episode, the members of the Midnight Society would gather around a campfire in the woods, and one member would be chosen tell a story—typically an urban legend or something involving ghosts, werewolves, vampires, witches, and the like. The storyteller would announce the title and toss a handful of "midnight dust" into the campfire—producing white smoke for extra ambience—before launching into the tale.
The rest of the episode would dramatize the story for the viewers. There was a fair share of humor mixed in with the jump scares and creepy moments, often courtesy of several colorful recurring characters like mad scientist/sorcerer Dr. Vink ("Vink. With a va-va-va!"), and magic shop owner Sardo ("No mister; accent on the doh!"). And few fans of the original series will soon forget terrifying monsters like the Ghastly Grinner.
The long summer recess for Congress is at last well and truly over. The House Judiciary Committee has ramped up for the fall season, issuing demands for huge piles of documentation from Apple, Amazon, Facebook, and Google as its antitrust probe into Big Tech grows.
The committee launched the bipartisan inquiry in June, seeking in part to determine "whether existing laws are adequate" to the task of regulating the sprawling tech titans that power the 21st century economy. As part of that probe, the committee has now issued lengthy requests for information to the four companies digging deeply into the question of competition.
The tech sector is facing scrutiny from all sides at the moment. The House investigation is separate and distinct from the various antitrust probes against the same four companies the Federal Trade Commission, the Department of Justice, and nearly all the states currently have in progress.
Amazon has announced that it will hold an event on September 25 to announce new hardware products. The company's invitations indicate that it will discuss "new things from the Amazon Devices and Services team" at the event.
Amazon held a similar event around the same time last year, when it announced a plethora of new devices, including a new Echo Dot, Sub, Show, and more—the majority of the Echo line was refreshed. That seems like a more likely focus for this year's event than the Fire TV, as Amazon announced new Fire TVs and a new Fire TV Cube at IFA just recently. However, Fire TV tablets are a possibility.
We're not sure whether it will be quite the gauntlet that last year's event was—Amazon announced more than a dozen products then. And there isn't a strong case to be made that the company's lineup is as in need of refreshes as it was then. But if you've bought into the Amazon ecosystem and Alexa, this is the event you'll want to keep an eye on to learn what new gear you can add to your setup.
