The first image of a black hole captured four years ago revealed a fuzzy, fiery doughnut-shaped object. Now, researchers have used artificial intelligence to give that cosmic beauty shot a touch-up.

The updated picture, published Thursday in the Astrophysical Journal Letters, keeps the original shape, but with a skinnier ring and a sharper resolution.

The image released in 2019 gave a peek at the enormous black hole at the center of the M87 galaxy, 53 million light-years from Earth. A light-year is 5.8 trillion miles. It was made using data gathered by a network of radio telescopes around the world, showing swirling light and gas.

But even with many telescopes working together, gaps remained in the data. In the latest study, scientists relied on the same data and used machine learning to fill in the missing pieces.

The resulting picture looks similar to the original, but with a thinner “doughnut” and a darker center, researchers said.

“For me, it feels like we’re really seeing it for the first time,” said lead author Lia Medeiros, an astrophysicist at the Institute for Advanced Study in New Jersey.

Medeiros said the team plans to use machine learning on other images of celestial objects, including possibly the black hole at the center of our Milky Way galaxy.

ChatGPT could return to Italy soon if its maker, OpenAI, complies with measures to satisfy regulators who had imposed a temporary ban on the artificial intelligence software over privacy worries.

The Italian data protection authority on Wednesday outlined a raft of requirements that OpenAI will have to satisfy by April 30 for the ban on AI chatbot to be lifted.

The watchdog last month ordered the company to temporarily stop processing Italian users’ personal information while it investigated a possible data breach. The authority said it didn’t want to hamper AI’s development but emphasized the importance of following the European Union’s strict data privacy rules.

OpenAI, which had responded by proposing remedies to ease the concerns, did not reply immediately to a request for comment Wednesday.

Concerns about boom grow

Concerns are growing about the artificial intelligence boom, with other countries, from France to Canada, investigating or looking closer at so-called generative AI technology like ChatGPT. The chatbot is “trained” on huge pools of data, including digital books and online writings, and able to generate text that mimics human writing styles.

Under Italy’s measures, OpenAI must post information on its website about how and why it processes the personal information of both users and non-users, as well as provide the option to correct or delete that data.

The company will have to rely on consent or “legitimate interest” to use personal data to train ChatGPT’s algorithms, the watchdog said.

Regulators question legal basis

The Italian regulators had questioned whether there’s a legal basis for OpenAI to collect massive amounts of data used to teach ChatGPT’s algorithms and raised concerns the system could sometimes generate false information about individuals.

San Francisco-based OpenAI also will have to carry out a publicity campaign by May 15 through radio and TV, newspapers and the internet to inform people about how it uses their personal data for training algorithms, Italy’s watchdog said.

There’s also a requirement to verify users’ ages and set up a system to filter out those who are under 13 and teens between 13 and 18 who don’t have parental consent.

“Only in that case will the Italian SA (supervisory authority) lift its order that placed a temporary limitation on the processing of Italian users’ data … so that ChatGPT will be available once again from Italy,” the watchdog said on its website.

A Biden administration proposal would force U.S. automakers to sharply increase their production of electric cars and trucks over the next decade, lending greater urgency to the effort to build raw material supply chains that reduce the industry’s dependence on China.

The Environmental Protection Agency on Wednesday announced a proposed rule that would place stricter limits on the average tailpipe emissions of vehicles built in the United States. The proposal would reduce the allowable limit by so much that automakers would have no way to comply unless about two-thirds of the vehicles they produce by 2032 are emission-free electric vehicles.

Automakers have generally recognized that EVs represent the future of the industry, but Wednesday’s proposal would greatly accelerate the trend. The proposal, which will be open to public comment before it is finalized, would greatly reduce a leading cause of air pollution in the U.S., as well as the greenhouse gases that contribute to global warming.

“By proposing the most ambitious pollution standards ever for cars and trucks, we are delivering on the Biden-Harris administration’s promise to protect people and the planet, securing critical reductions in dangerous air and climate pollution, and ensuring significant economic benefits like lower fuel and maintenance costs for families,” said EPA Administrator Michael Regan.

The proposal, which would apply to new light-duty vehicles made in 2027 and beyond, would be the strictest environmental standard the federal government has ever applied to automobiles. If it does force the industry to make EVs account for two-thirds of production, it could also exceed President Joe Biden’s previously articulated target of making 50% of new cars either plug-in hybrids or completely emission-free by 2030.

Supply chain questions

Well before the EPA released its proposed rule Wednesday, the Biden administration had been moving to strengthen the EV market in the U.S. and to build a pipeline for raw materials that would reduce the auto industry’s reliance on China for key raw materials.

Accomplishing that reduction will be no small task. According to an analysis by the International Energy Agency last year, China produced three-quarters of the world’s lithium-ion batteries, the key component in the majority of EVs on the road.

China also has a dominant hold on much of the market for the components of those batteries, including lithium, cobalt and graphite. According to the IEA, more than half of the world’s capacity for processing and refining those materials is located in China.

According to the IEA, as of last year, the U.S. accounted for only 10% of EV production worldwide, and just 7% of production capacity for batteries.

Infrastructure projects

Last year’s passage of the Inflation Reduction Act, which contained hundreds of billions of dollars in climate-related spending, included the creation of large tax breaks restricted to EVs made at least partly in the U.S. The tax breaks are meant to extend over several years, but the restrictions become tighter as time goes on, creating incentives for manufacturers to “onshore” production to the U.S.

Tax breaks specific to the batteries used in EVs require that the raw materials used to assemble them come from domestic sources or from countries with which the U.S. has existing trade agreements.

Other pieces of legislation meant to spur investment in the U.S., including a major bipartisan infrastructure bill and the CHIPS and Science Act, also contain money and incentives that will help build out electric infrastructure in the U.S.

Achievable goals

Luke Tonachel, senior director for clean vehicles and buildings with the Natural Resources Defense Council, told VOA that building an EV supply chain centered on domestic production and imports from friendly countries is ambitious, but achievable.

Tonachel said the necessary raw materials are available from U.S. allies, but that the capacity for processing them needs to be built domestically. He said the creation of that capacity is already underway.

“There are robust incentives for building out that battery manufacturing and supply chain here in the U.S.,” he said, adding that he believes the administration’s time frame is feasible, especially now that the new standards have created certainty about future demand for EVs.

“It is realistic,” he said. “These are technologies that are known. We can certainly get more economies of scale as we ramp up production.”

Automakers tentative

Industry representatives said achieving the administration’s goal will require that a lot of disparate efforts be successful at the same time, not all of which are under their control. For example, a nationwide network of charging stations and the increased capacity to meet new demand for power will be essential to driving customer demand.

“It’s aggressive, and a lot of pieces have to work perfectly together,” Genevieve Cullen, president of the Electric Drive Transportation Association, told VOA. “Aside from the technology piece, the market piece has to work, and supply chain speed is part of that. Consumer incentives are working to help bring them into the equation, and we need to keep expanding infrastructure at a pace that meets, and perhaps exceeds, the needs in the beginning so that people feel the confidence that they need to switch to battery electric.”

John Bozzella, president of the trade group Alliance for Automotive Innovation, said in a blog post Wednesday that the administration’s plan is “aggressive by any measure” and that its success would depend on more than just automakers being able to ramp up production.

“To some extent, the baseline policy framework for the transition has come into focus,” Bozzella said. “But it remains to be seen whether the refueling infrastructure incentives and supply-side provisions of the Inflation Reduction Act, the bipartisan infrastructure law, and the CHIPS and Science Act are sufficient to support electrification at the levels envisioned by the proposed standards over the coming years.”

Broadcaster National Public Radio said Wednesday it would no longer post its news content on 52 official Twitter accounts in protest of the social media site labeling the independent U.S. news agency as “government-funded media.” 

NPR is the first major news organization to go silent on Twitter. The social media platform owned by entrepreneur Elon Musk at first labeled NPR as “state-affiliated media,” the same tag it applies to propaganda outlets in China, Russia and other autocratic countries. 

Twitter then revised its label to “government-funded media,” but NPR said that, too, was misleading because NPR is a private, nonprofit company with editorial independence. NPR says it receives less than 1% of its $300 million annual budget from the federally funded Corporation for Public Broadcasting.  

NPR chief executive John Lansing said that by not posting its news reports on Twitter, the network is protecting its credibility and would continue to produce journalism without “a shadow of negativity.” 

In an email to staff explaining the decision, Lansing wrote, “It would be a disservice to the serious work you all do here to continue to share it on a platform that is associating the federal charter for public media with an abandoning of editorial independence or standards.”  

He said that even if Twitter were to drop any description of NPR, the network would not immediately return to the platform. 

“At this point I have lost my faith in the decision-making at Twitter,” Lansing said in an article posted by NPR. “I would need some time to understand whether Twitter can be trusted again.”

Twitter has also labeled Voice of America, a U.S. government-funded but independent news agency, and the BBC in Britain, as “government-funded media,” a description more commonly employed in describing state-controlled propaganda outlets. VOA has not dropped its use of Twitter but said its description of the news outlet left the impression that it was not independent. 

Bridget Serchak, VOA’s director of public relations, said, “The label ‘government funded’ is potentially misleading and could be construed as also ‘government-controlled’ — which VOA is most certainly not.” 

“Our editorial firewall, enshrined in the law, prohibits any interference from government officials at any level in its news coverage and editorial decision-making process,” Serchak said in an email. “VOA will continue to emphasize this distinction in our discussions with Twitter, as this new label on our network causes unwarranted and unjustified concern about the accuracy and objectivity of our news coverage.” 

VOA is funded by the U.S. government and is part of the U.S. Agency for Global Media, but its editorial independence is protected by regulations and a firewall. The BBC said it “is, and always has been, independent.” 

Press freedom advocates have also objected to Twitter’s labeling of NPR, VOA and the BBC.

“The confusion between media serving the general interest and propaganda media is dangerous, and is yet further proof that social media platforms are not competent to identify what is and is not journalism,” Vincent Berthier, head of the technology desk at Reporters Without Borders, said in a statement.

Billionaire Elon Musk has told the BBC that running Twitter has been “quite painful” but that the social media company is now roughly breaking even after he acquired it late last year.

In an interview also streamed live late Tuesday on Twitter Spaces, Musk discussed his ownership of the online platform, including layoffs, misinformation and his work style.

“It’s not been boring. It’s quite a rollercoaster,” he told the U.K. broadcaster at Twitter’s San Francisco headquarters.

It was a rare chance for a mainstream news outlet to interview Musk, who also owns Tesla and SpaceX. After buying Twitter for $44 billion last year, Musk’s changes included eliminating the company’s communications department.

Reporters who email the company to seek comment now receive an auto-reply with a poop emoji.

The interview was sometimes tense, with Musk challenging the reporter to back up assertions about rising levels of hate speech on the platform. At other times, Musk laughed at his own jokes, mentioning more than once that he wasn’t the CEO but his dog Floki was.

He also revealed that he sometimes sleeps on a couch at Twitter’s San Francisco office.

Advertisers who had shunned the platform in the wake of Musk’s tumultuous acquisition have mostly returned, the billionaire said, without providing details.

Musk predicted that Twitter could become “cash flow positive” in the current quarter “if current trends continue.” Because Twitter is a private company, information about its finances can’t be verified.

After acquiring the platform, Musk carried out mass layoffs as part of cost-cutting efforts. He said Twitter’s workforce has been slashed to about 1,500 employees from about 8,000 previously, describing it as something that had to be done.

“It’s not fun at all,” Musk said. “The company’s going to go bankrupt if we don’t cut costs immediately. This is not a caring-uncaring situation. It’s like if the whole ship sinks, then nobody’s got a job.”

Asked if he regretted buying the company, he said it was something that “needed to be done.”

“The pain level of Twitter has been extremely high. This hasn’t been some sort of party,” Musk said.
