How Thinking Hard Makes the Brain Tired

SlashDot - Fri, 2022-08-12 14:01
An anonymous reader shares a report: Physical labour is exhausting. A long run or a hard day's sweat depletes the body's energy stores, resulting in a sense of fatigue. Mental labour can also be exhausting. Even resisting that last glistening chocolate-chip cookie after a long day at a consuming desk job is difficult. Cognitive control, the umbrella term encompassing mental exertion, self-control and willpower, also fades with effort. But unlike the mechanism of physical fatigue, the cause of cognitive fatigue has been poorly understood. Previous accounts were incomplete. One of the most widely known, the biological one, draws from what is known about muscular fatigue. It posits that exerting cognitive control uses up energy in the form of glucose. At the end of a day spent intensely cogitating, the brain is metaphorically running on fumes. The problem with this version of events is that the energy cost associated with thinking is minimal. One analysis of previous studies suggests that cognitively overworked and "depleted" brains use less than one-tenth of a Tic-Tac's worth of additional glucose. If cognitive fatigue is not caused by a lack of energy, then what explains it? A team of scientists led by Antonius Wiehler of Pitie-Salpetriere University Hospital, in Paris, looked at things from what is termed a neurometabolic point of view. They hypothesise that cognitive fatigue results from an accumulation of a certain chemical in the region of the brain underpinning control. That substance, glutamate, is an excitatory neurotransmitter that abounds in the central nervous systems of mammals and plays a role in a multitude of activities, such as learning, memory and the sleep-wake cycle. In other words, cognitive work results in chemical changes in the brain, which present behaviourally as fatigue. This, therefore, is a signal to stop working in order to restore balance to the brain. In their new paper in Current Biology, the researchers describe an experiment they undertook to explain how all this happens.

Google Adds Instant Cloud-Streaming Button To Web Searches For Games

SlashDot - Fri, 2022-08-12 13:25
An anonymous reader shares a report: The earliest sales pitch for Stadia, the Google streaming service that beams high-end video games to web browsers via the cloud, included the idea that it might work as simply as Googling your favorite game. You might search for a popular game to learn more about it, only to immediately see an option to start playing it inside your web browser, no additional hardware required -- and perhaps no payment, either. Nearly three years after Stadia's official launch -- and 18 months after the service's massive internal downgrade -- that scenario has finally begun to play out. What's more, the feature appears to be streamer-agnostic, as multiple Stadia-like streaming services have started appearing in search results. This week, Google rolled out a limited launch of a "Play Now" tab that appears on searches for select video games on desktop browsers. (As of press time, out of three Google accounts tested, the search results shown in this article only appear on one of them.) This tab can be found in the right-hand "knowledge panel" that is otherwise automatically populated with user reviews, game details, and digital download purchase links. When a Google game search returns a Play Now tab, it will include as many compatible streaming services as possible, including Google Stadia, Microsoft Xbox Cloud Gaming, Amazon Luna, and Nvidia GeForce Now. Each entry shows what kind of fee may be required to play the game. Conveniently enough, many Google Stadia games can now be played for free for the first 30 minutes or as long as 120 minutes, and supported free-trial Stadia games get a bright-green flash of italicized text: "trial available." Other games and services that have appeared thus far have included tags like "premium subscription" or "free-to-play."

South Korea To Pardon Samsung's Lee, Other Corporate Giants

SlashDot - Fri, 2022-08-12 12:45
Samsung's de-facto leader secured a pardon Friday of his conviction for bribing a former president in a corruption scandal that toppled a previous South Korean government, an act of leniency that underscored the tech company's huge influence in the nation. From a report: Lee Jae-yong's pardon is partially symbolic since he was released on parole a year ago after serving 18 months of a prison term that would have ended in July, and critics say the billionaire has remained in control of Samsung even while behind bars. Still, the pardon will allow the heir to the electronics juggernaut to fully resume his management duties and could make it easier for the company to pursue investments and mergers. The Justice Ministry said President Yoon Suk Yeol, who as a prosecutor investigated the corruption scandal involving Lee, will issue the pardon Monday, a national holiday when some 1,700 people are set to receive clemency, including other top business leaders. Lee, 54, was convicted in 2017 of bribing former President Park Geun-hye and her close confidante to win government support for a merger between two Samsung affiliates that tightened Lee's control over the corporate empire. Park and the confidante were also convicted in the scandal, which enraged South Koreans, who staged massive protests for months demanding an end to the shady ties between business and politics. The demonstrations eventually led to Park's ouster from office. [...] Justice Minister Han Dong-hoon said the pardons of the business tycoons were aimed at "overcoming the economic crisis through encouraging business activity" at a time when South Koreans are grappling with rising prices, high personal debt and a faltering job market.

Inside the Apple vs. Facebook Privacy Fight

SlashDot - Fri, 2022-08-12 12:01
An ongoing dispute over privacy between Apple and Facebook is roiling the digital economy, leading companies to shift billions in ad spending as users continue to limit the data available to advertisers. The feud took off last year, when Apple rolled out iOS 14.5, a version of its mobile operating system that made it easier than ever for iPhone and iPad users to opt out of letting apps like Facebook track their activity on their devices. The two companies weren't always at odds. In fact, they were almost business partners. From a report: In the years before the change, Apple suggested a series of possible arrangements that would earn the iPhone maker a slice of Facebook's revenue, according to people who either participated in the meetings or were briefed about them. As one person recalled: Apple officials said they wanted to "build businesses together." One idea that was discussed: creating a subscription-based version of Facebook that would be free of ads, according to people familiar with the discussions. Because Apple collects a cut of subscription revenue for apps in its App Store, that product could have generated significant revenue for the Cupertino, Calif., giant. The companies also haggled over whether Apple was entitled to a piece of Facebook's sales from so-called boosted posts, said people familiar with the matter. A boost allows a user to pay to increase the number of people that see a post on Facebook or Instagram. Facebook, which considers boosts ads, has always contended that boosts are a form of advertising, in part because they are often used by small businesses to reach a bigger audience, said one of the people. Apple, which doesn't take a cut of advertising from developers, argued that Facebook boosts should be considered in-app purchases, according to a person familiar with the matter. Apple's standard terms would entitle it to take a 30% share of those sales.

Suspected Developer of Crypto Mixer Tornado Cash Arrested

SlashDot - Fri, 2022-08-12 11:22
The Dutch government agency responsible for investigating financial crimes said it has arrested an individual suspected of being a developer of the U.S.-sanctioned crypto mixing service Tornado Cash in a move that has rattled some crypto and privacy advocates. From a report: The Fiscal Information and Investigation Service said Friday that the arrested 29-year-old man is suspected to be involved in "concealing criminal financial flows and facilitating money laundering" through the popular crypto mixing service. "Multiple arrests are not ruled out," it said. The agency added that it arrested the individual in Amsterdam. The move comes days after the U.S. government sanctioned Tornado Cash -- a service that allows users to mask their transactions by jumbling funds from different sources before sending them to the ultimate destination -- for its role in enabling billions of dollars' worth of cryptocurrency to be laundered through its platform.

China's Golden Era of Smartphones Is Ending

SlashDot - Fri, 2022-08-12 10:42
The world's largest smartphone market is in deep trouble. China saw a 14.7% decline in phone shipments in the second quarter, according to research firm IDC. And multibillion-dollar pillars of the industry like Xiaomi Corp., Vivo and Oppo all reported steep sales declines. From a report: Many factors drove the fall, including a strict Covid Zero policy that torpedoed demand, but the bigger issue is one that's long been feared by the country's smartphone makers. China's 10-year-plus smartphone boom, fueled by new buyers and ceaseless upgrades, is likely coming to an end. China was eager to become a mobile nation a decade ago. It used state capital to build 4G base stations in almost every village, enabling brands like Oppo and Vivo to sell chic-looking devices to hundreds of millions of people in rural areas, most of whom had never tried a touchscreen. Apple, Samsung Electronics and Motorola pursued tech-savvy city dwellers with more expensive options. (Although the latter two quickly fell out of the game due to product flaws, marketing missteps and geopolitical pressures.) More recently, smartphone makers saw an opportunity as China pushed toward advanced 5G networks. But few saw the trouble already brewing. A key problem is that China's massive smartphone market has become highly saturated. The country has more than 1.6 billion active mobile phone accounts by the end of last year compared to its 1.4 billion population. The penetration rate is well above the global average and has led to fierce competition. The need to replace phones has also dwindled. The life cycles of smartphones are getting longer, and can be stretched when the economy isn't doing well. The price of 5G service has prompted many people in China to simply keep their adequate 4G subscriptions.
