Shortages of semiconductors are battering automakers and tech giants, raising alarm bells from Washington to Brussels to Beijing. The crunch has raised a fundamental question for policymakers, customers, and investors: Why can’t we just make more chips?
There is both a simple answer and a complicated one. The simple version is that making chips is incredibly difficult—and getting tougher.
“It’s not rocket science—it’s much more difficult,” goes one of the industry’s inside jokes.
The more complicated answer is that it takes years to build semiconductor fabrication facilities and billions of dollars—and even then the economics are so brutal that you can lose out if your manufacturing expertise is a fraction behind the competition. Former Intel Corp. boss Craig Barrett called his company’s microprocessors the most complicated devices ever made by man.
This is why countries face such difficulty in achieving semiconductor self-sufficiency. China has called chip independence a top national priority in its latest five-year plan, while U.S. President Joe Biden has vowed to build a secure American supply chain by reviving domestic manufacturing. Even the European Union is mulling measures to make its own chips. But success is anything but assured.

How much energy does an industry deserve to consume? Right now, organizations around the world are facing pressure to limit the consumption of non-renewable energy sources and the emission of carbon into the atmosphere. But figuring out how much consumption is too much is a complex question that’s intertwined with debates around our priorities as a society. The calculation of which goods and services are “worth” spending these resources on, after all, is really a question of values. As cryptocurrencies, and Bitcoin, in particular, have grown in prominence, energy use has become the latest flashpoint in the larger conversation about what, and who, digital currencies are really good for.
On the face of it, the question about energy use is a fair one. According to the Cambridge Center for Alternative Finance (CCAF), Bitcoin currently consumes around 110 Terawatt Hours per year — 0.55% of global electricity production, or roughly equivalent to the annual energy draw of small countries like Malaysia or Sweden. This certainly sounds like a lot of energy. But how much energy should a monetary system consume?

The full moon on Wednesday, May 26, will be the first total lunar eclipse since January 2019, according to EarthSky. It will take the moon just under three hours to cross through the Earth’s shadow, but the actual lunar eclipse will last for about 15 minutes.
A lunar eclipse happens when the sun, Earth and full moon align. During the eclipse, the moon will have a reddish hue from the sunlight filtering through Earth’s atmosphere, according to NASA. Many have labeled this a “blood moon.”
Depending on your location, you might be able to get a glimpse of part of the eclipse. Most of North and South America will be able to see it in the early morning hours while eastern Asia and Australia will see it in the evening.
In the United States, the total eclipse will begin at 7:11 a.m. ET and end at 7:26 a.m. ET, but will be partially visible from 5:45 a.m. ET to 8:52 a.m. ET. To check whether you’ll be able to see the eclipse where you live, go to timeanddate.com.
It’s also the “flower” supermoon, and it will be the closest moon to Earth in 2021, according to EarthSky. The moon will be 100% full at 7:14 a.m. ET.

All eyes will be on the sky on Wednesday, May 26, because a total lunar eclipse will occur as the full “supermoon” starts to set in the early morning.
Although the lunar eclipse will look impressive in some parts of the United States, because the moon will turn a reddish-brown “blood” color, skywatchers in other parts of the nation — including New York, New Jersey, and Pennsylvania — will miss out on the big event.
For us folks in the eastern U.S., “it’s just gonna look like a full moon,” said Amie Gallagher, director of the planetarium at Raritan Valley Community College in Somerset County.
It all comes down to the timing, Gallagher said, noting that the lunar eclipse — when the full moon moves across the Earth’s shadow — will start to happen in our region just after the moon sets in the west-southwestern sky.
People in other time zones in the United States, where it’s still dark outside and the moon is still visible in the sky, will get to see a good show, according to Gallagher and other astronomy experts.
“Unfortunately, those who live in the eastern third of the United States will see little or nothing of this event, because when the visual show begins to get underway, the moon will either be approaching its setting or will have already set,” says Space.com.

You know how your heart melts whenever a pup raises its eyebrows? That’s no accident. While research on non-human animals has long suggested that facial expressions are involuntary, it turns out dogs may be different, and like humans, able to control their facial expressions to get what they want. Are you really surprised?
In a 2017 study published in the journal Scientific Reports, researchers tested whether dogs illustrated the “audience effect.” They found that dogs reacted with more noticeable facial expressions when humans were around than when there were no humans around, suggesting that dogs use facial expressions to voluntarily communicate.
A team of researchers at the University of Portsmouth Dog Cognition Centre devised an experiment to investigate whether dogs’ facial expressions are subject to audience effects, which simply means that they wanted to see whether dogs made different faces when they thought they weren’t being watched. This would suggest that they’re voluntarily controlling their facial expressions, changing what we know about animal behavior.

AfterAfter years of positive vibes about the future of autonomous vehicles and nearly unrestricted access to cash from Kool-Aid-drunk venture capitalists, the AV industry is confronting some hard truths. The first is that autonomous vehicles are going to take a lot longer to reach mass scale than previously thought. The second is that it’s going to be a lot more expensive, too. And the third hard truth: going it alone is no longer a viable option.
Last week, Lyft sold its self-driving car division to a subsidiary of Toyota for $550 million. Cruise bought Voyage. Aurora merged with Uber’s autonomous vehicle unit. Delivery robot startup Nuro acquired self-driving truck outfit Ike. There have been so many mergers, joint ventures, and various tie-ups lately it can be difficult to keep them all straight.
Where that leaves things is a little unclear. There is still money flowing to these companies, and nearly all of the executives, engineers, and software developers working on the technology remain bullish about the future. But there is a growing sense among experts and investors that the heady days when anyone with a couple of test vehicles, some LIDAR, and a vision for the future could launch a startup are at an end. And there will definitely be more shrinkage to come.

Is our mother still with us?
Sometimes, it’s hard to tell. On her best days, she can manage whole sentences, though occasionally they’ll be in Arabic, her first language. Other times her words are mangled between what remains of her mind and her lips — or they’re lost altogether.
Our mother used to talk: Fast and loud, with a distinctive clipped cadence. She summoned so many words: Tender and withering and funny and angry and illuminating and painful and comforting. Our mother was fierce, a woman of unnatural will who withstood decades that should have broken her.
Her body has a mind of its own, separate and apart from the one ravaged by Alzheimer’s. It is defiant, unbowed after bearing six children and raising them alone, after countless beatings, after years on her feet working in factories and bars, after lying awake each night worrying about whether we had enough and who we’d become. Even at 84, her body continues its relentless march forward. Her brain hurtles in the opposite direction, the regressions cascading.
