More than 8,000 of the world's most-cited scientists have at least one retraction, according to a database that links retractions to top-cited papers. From a report: An analysis of the database, published in PLOS Biology on 30 January, attempts to map the scale of retractions and understand how they manifest. "Not every retraction is a sign of misconduct," says John Ioannidis, an epidemiologist at Stanford University in California, who led the study. "But it is important to have a bird's eye view, across all scientific fields, [of] people who are most influential in science." Retracted papers had a higher number of self-citations than did non-retracted papers. And papers with higher co-authorship numbers were more likely to be retracted than those with fewer co-authors. [...] In the study, the authors split the most-cited scientists into two groups. The first featured the 217,097 authors who were among the top 2% most-cited in their fields over their careers. The second group comprised the 223,152 scientists who made up the top 2% for citation impact in 2023, the most recent year for which there were data. The authors found that 8,747 (4%) of the most highly cited researchers in 2023 had at least one retraction during their career, as did 7,083 (3.3%) of the researchers who were most-cited over their careers.

A study has found microplastic and nanoplastic pollution to be significantly higher in placentas from premature births than in those from full-term births. From a report: The levels were much higher than previously detected in blood, suggesting the tiny plastic particles were accumulating in the placenta. But the higher average levels found in the shorter pregnancies were a "big surprise" for the researchers, as longer terms could be expected to lead to more accumulation. Preterm birth is the leading cause of infant death worldwide, and the reasons for about two-thirds of all preterm births were unknown, said Dr Enrico Barrozo, of Baylor College of Medicine in Texas, US. The established link between air pollution and millions of premature births had spurred the research team to investigate plastic pollution. The new study only demonstrates an association between microplastics and premature births. Further research is needed in cell cultures and animal models to determine if the link is causal. Microplastics are known to cause inflammation in human cells, and inflammation is one of the factors that prompts the start of labour.

An anonymous reader shares a report: Taiwan's digital ministry said on Friday that government departments should not use Chinese startup DeepSeek's artificial intelligence (AI) service, saying that as the product is from China it represents a security concern. Democratically-governed Taiwan has long been wary of Chinese tech given Beijing's sovereignty claims over the island and its military and political threats against the government in Taipei. In a statement, Taiwan's Ministry of Digital Affairs said that government departments are not allowed to use DeepSeek's AI service to "prevent information security risks". "DeepSeek's AI service is a Chinese product, and its operation involves cross-border transmission and information leakage and other information security concerns, and is a product that jeopardises the country's information security," the ministry said.

Apple has filed an emergency motion [PDF] for a stay in the Google antitrust trial, warning that it faces "clear and substantial irreparable harm" if barred from participating in the case's remedies phase. The motion, filed on January 30, 2025, comes after Judge Amit Mehta denied Apple's request for limited intervention earlier in the week. Apple -- which makes more than $20 billion a year from Google to use the Android-maker's search engine on Safari -- argues that the U.S. Department of Justice's (DOJ) proposed remedy -- which includes a prohibition on "any contract between Google and Apple in which there would be anything exchanged of value" --would prevent it from negotiating agreements that benefit millions of users. Without the ability to fully participate, Apple contends it will be left as a "mere spectator" while the government pursues restrictions that directly impact its business interests. The company asserts that intervention is necessary to develop evidence, participate in discovery, and cross-examine witnesses regarding its market role and incentives. Apple also seeks access to trial records while its appeal is pending, including witness lists, depositions, and discovery materials, to ensure it can respond effectively if granted party status.

Nearly 100 journalists and other members of civil society using WhatsApp, the popular messaging app owned by Meta, were targeted by spyware owned by Paragon, an Israeli maker of hacking software, the company alleged today. From a report: The journalists and other civil society members were being alerted of a possible breach of their devices, with WhatsApp telling the Guardian it had "high confidence" that the users in question had been targeted and "possibly compromised." The company declined to disclose where the journalists and members of civil society were based, including whether they were based in the US. The company said it had sent Paragon a "cease and desist" letter and that it was exploring its legal options. WhatsApp said the alleged attacks had been disrupted in December and that it was not clear how long the targets may have been under threat.

An anonymous reader quotes a report from MIT Technology Review: A Canadian startup called Xanadu has built a new quantum computer it says can be easily scaled up to achieve the computational power needed to tackle scientific challenges ranging from drug discovery to more energy-efficient machine learning. Aurora is a "photonic" quantum computer, which means it crunches numbers using photonic qubits -- information encoded in light. In practice, this means combining and recombining laser beams on multiple chips using lenses, fibers, and other optics according to an algorithm. Xanadu's computer is designed in such a way that the answer to an algorithm it executes corresponds to the final number of photons in each laser beam. This approach differs from one used by Google and IBM, which involves encoding information in properties of superconducting circuits. Aurora has a modular design that consists of four similar units, each installed in a standard server rack that is slightly taller and wider than the average human. To make a useful quantum computer, "you copy and paste a thousand of these things and network them together," says Christian Weedbrook, the CEO and founder of the company. Ultimately, Xanadu envisions a quantum computer as a specialized data center, consisting of rows upon rows of these servers. This contrasts with the industry's earlier conception of a specialized chip within a supercomputer, much like a GPU. [...] Xanadu's 12 qubits may seem like a paltry number next to IBM's 1,121, but Tiwari says this doesn't mean that quantum computers based on photonics are running behind. In his opinion, the number of qubits reflects the amount of investment more than it does the technology's promise. [...] Xanadu's next goal is to improve the quality of the photons in the computer, which will ease the error correction requirements. "When you send lasers through a medium, whether it's free space, chips, or fiber optics, not all the information makes it from the start to the finish," he says. "So you're actually losing light and therefore losing information." The company is working to reduce this loss, which means fewer errors in the first place. Xanadu aims to build a quantum data center, with thousands of servers containing a million qubits, in 2029. The company published its work on chip design optimization and fabrication in the journal Nature.

During the company's fourth-quarter earnings call Thursday, Intel co-CEO Michelle Johnston Holthaus announced that Intel has decided to cancel its Falcon Shores AI chip. Instead, it'll opt to use it as an internal test chip while shifting focus to Jaguar Shores for AI data center solutions. TechCrunch reports: "AI data center ... is an attractive market for us," Holthaus said during the call. "[B]ut I am not happy with where we are today. We're not yet participating in the cloud-based AI data center market in a meaningful way ... One of the immediate actions I have taken is to simplify our roadmap and concentrate our resources." The focus instead will be on Jaguar Shores, which Holthaus called Intel's opportunity to "develop a system-level solution at rack scale ... to address the AI data center more broadly." Holthaus tempered expectations for Falcon Shores last month, when she implied that it was an "iterative" step over the company's previous dedicated AI data center chip, Gaudi 3. "One of the things that we've learned from Gaudi is, it's not enough to just deliver the silicon," Holthaus said during Thursday's earnings call. "Falcon Shores will help us in that process of working on the system, networking, memory -- all those component[s]. But what customers really want is that full-scale rack solution, and so we're able to get to that with Jaguar Shores." "As I think about our AI opportunity, my focus is on the problems our customers are trying to solve, most notably the need to lower the cost and increase the efficiency of compute," Holthaus said. "As such, a one-size-fits-all approach will not work, and I can see clear opportunities to leverage our core assets in new ways to drive the most compelling total cost of ownership across the continuum."

A bipartisan group of legislators has reintroduced the AM Radio for Every Vehicle Act of 2025, aiming to mandate AM radio in all new vehicles at no additional cost. Adweek reports: The AM Radio for Every Vehicle Act was first introduced in May 2023. It continued to take on new co-sponsors through the fall of 2024. It was reintroduced as the AM Radio for Every Vehicle Act of 2025 with 62 cosponsors. Upper Midwest senators showing support for the bill include Sens. John Hoeven and Kevin Cramer R-North Dakota, and Sens. Amy Klobuchar and Tina Smith, DFL- Minnesota. If enacted, the bill would require the Department of Transportation to issue a rule requiring new vehicles to maintain access to broadcast AM radio at no additional cost to the consumer and provide small vehicle manufacturers at least four years after the date DOT issues the rule to comply. The act also requires automakers to inform consumers, during the period before the rule takes effect, that the vehicles do not maintain access to broadcast AM radio. "With 82 million Americans tuning in each month, AM radio delivers more than just emergency alerts," says the National Association of Broadcasters in a news release. "It connects communities through hyper-local content, including news, weather and diverse cultural programming," according to a news release from the National Association of Broadcasters."
