OpenAI Has Created an AI Model For Longevity Science

✇Slashdot

OpenAI has developed a language model designed for engineering proteins, capable of converting regular cells into stem cells. It marks the company's first venture into biological data and demonstrates AI's potential for unexpected scientific discoveries. An anonymous reader quotes a report from MIT Technology Review: Last week, OpenAI CEO Sam Altman said he was "confident" his company knows how to build an AGI, adding that "superintelligent tools could massively accelerate scientific discovery and innovation well beyond what we are capable of doing on our own." The protein engineering project started a year ago when Retro Biosciences, a longevity research company based in San Francisco, approached OpenAI about working together. That link-up did not happen by chance. Sam Altman, the CEO of OpenAI, personally funded Retro with $180 million, as MIT Technology Review first reported in 2023. Retro has the goal of extending the normal human lifespan by 10 years. For that, it studies what are called Yamanaka factors. Those are a set of proteins that, when added to a human skin cell, will cause it to morph into a young-seeming stem cell, a type that can produce any other tissue in the body. [...] OpenAI's new model, called GPT-4b micro, was trained to suggest ways to re-engineer the protein factors to increase their function. According to OpenAI, researchers used the model's suggestions to change two of the Yamanaka factors to be more than 50 times as effective -- at least according to some preliminary measures. [...] The model does not work the same way as Google's AlphaFold, which predicts what shape proteins will take. Since the Yamanaka factors are unusually floppy and unstructured proteins, OpenAI said, they called for a different approach, which its large language models were suited to. The model was trained on examples of protein sequences from many species, as well as information on which proteins tend to interact with one another. While that's a lot of data, it's just a fraction of what OpenAI's flagship chatbots were trained on, making GPT-4b an example of a "small language model" that works with a focused data set. Once Retro scientists were given the model, they tried to steer it to suggest possible redesigns of the Yamanaka proteins. The prompting tactic used is similar to the "few-shot" method, in which a user queries a chatbot by providing a series of examples with answers, followed by an example for the bot to respond to. Although genetic engineers have ways to direct evolution of molecules in the lab, they can usually test only so many possibilities. And even a protein of typical length can be changed in nearly infinite ways (since they're built from hundreds of amino acids, and each acid comes in 20 possible varieties). OpenAI's model, however, often spits out suggestions in which a third of the amino acids in the proteins were changed. "We threw this model into the lab immediately and we got real-world results," says Retro's CEO, Joe Betts-Lacroix. He says the model's ideas were unusually good, leading to improvements over the original Yamanaka factors in a substantial fraction of cases.

Sales of electric vehicles and hybrids reached 20% of new car sales in the U.S. last year, with Tesla maintaining dominance in the EV market despite a slight decline in market share. CNBC reports: Auto data firm Motor Intelligence reports more than 3.2 million "electrified" vehicles were sold last year, or 1.9 million hybrid vehicles, including plug-in models, and 1.3 million all-electric models. Traditional vehicles with gas or diesel internal combustion engines still made up the majority of sales, but declined to 79.8%, falling under 80% for the first time in modern automotive history, according to the data. Regarding sales of pure EVs, Tesla continued to dominate, but Cox Automotive estimated its annual sales fell and its market share dropped to about 49%, down from 55% in 2023. The Tesla Model Y and Model 3 were estimated to be the bestselling EVs in 2024. Following Tesla in EV sales was Hyundai Motor, including Kia, at 9.3% of EV market share; General Motors at 8.7%; and then Ford Motor at 7.5%, according to Motor Intelligence. BMW rounded out the top five at 4.1%. The EV market in the U.S. is highly competitive: Of the 68 mainstream EV models tracked by Cox's Kelley Blue Book, 24 models posted year-over-year sales increases; 17 models were all new to the market; and 27 decreased in volume.

"The FDIC sued 17 former executives and directors of Silicon Valley Bank on Thursday, seeking to recover billions of dollars for alleged gross negligence and breaches of fiduciary duty," reports Reuters. The move comes almost two years after Silicon Valley Bank's March 2023 collapse, which shocked financial markets and ended up benefiting big players like JPMorgan Chase. From the report: In a complaint filed in San Francisco federal court, the FDIC, in its capacity the bank's receiver, said the defendants ignored fundamental standards of prudent banking and the bank's own risk policies in letting the bank take on excessive risks to boost short-term profit and its stock price. The FDIC faulted the bank's overreliance on unhedged, interest rate-sensitive long-term government bonds such as US Treasuries and mortgage-backed securities, as rates looked set to -- and eventually did -- rise. It also objected to the payment of a "grossly imprudent" $294 million dividend to its parent that drained needed capital "at a time of financial distress and management weakness" in December 2022, less than three months before its demise. "SVB represents a case of egregious mismanagement of interest-rate and liquidity risks by the bank's former officers and directors," the complaint said. The defendants include former Chief Executive Gregory Becker, former Chief Financial Officer Daniel Beck, four other former executives and 11 former directors.

Google Reports Halving Code Migration Time With AI Help

✇Slashdot
Par : BeauHD
18 janvier 2025 à 00:02
Google computer scientists have been using LLMs to streamline internal code migrations, achieving significant time savings of up to 89% in some cases. The findings appear in a pre-print paper titled "How is Google using AI for internal code migrations?" The Register reports: Their focus is on bespoke AI tools developed for specific product areas, such as Ads, Search, Workspace and YouTube, instead of generic AI tools that provide broadly applicable services like code completion, code review, and question answering. Google's code migrations involved: changing 32-bit IDs in the 500-plus-million-line codebase for Google Ads to 64-bit IDs; converting its old JUnit3 testing library to JUnit4; and replacing the Joda time library with Java's standard java.time package. The int32 to int64 migration, the Googlers explain, was not trivial as the IDs were often generically defined (int32_t in C++ or Integer in Java) and were not easily searchable. They existed in tens of thousands of code locations across thousands of files. Changes had to be tracked across multiple teams and changes to class interfaces had to be considered across multiple files. "The full effort, if done manually, was expected to require hundreds of software engineering years and complex crossteam coordination," the authors explain. For their LLM-based workflow, Google's software engineers implemented the following process. An engineer from Ads would identify an ID in need of migration using a combination of code search, Kythe, and custom scripts. Then an LLM-based migration toolkit, triggered by someone knowledgeable in the art, was run to generate verified changes containing code that passed unit tests. Those changes would be manually checked by the same engineer and potentially corrected. Thereafter, the code changes would be sent to multiple reviewers who are responsible for the portion of the codebase affected by the changes. The result was that 80 percent of the code modifications in the change lists (CLs) were purely the product of AI; the remainder were either human-authored or human-edited AI suggestions. "We discovered that in most cases, the human needed to revert at least some changes the model made that were either incorrect or not necessary," the authors observe. "Given the complexity and sensitive nature of the modified code, effort has to be spent in carefully rolling out each change to users." Based on this, Google undertook further work on LLM-driven verification to reduce the need for detailed review. Even with the need to double-check the LLM's work, the authors estimate that the time required to complete the migration was reduced by 50 percent. With LLM assistance, it took just three months to migrate 5,359 files and modify 149,000 lines of code to complete the JUnit3-JUnit4 transition. Approximately 87 percent of the code generated by AI ended up being committed with no changes. As for the Joda-Java time framework switch, the authors estimate a time saving of 89 percent compared to the projected manual change time, though no specifics were provided to support that assertion.

Longtime Slashdot reader tlhIngan writes: In what is perhaps the greatest irony ever, the operators of RedNote (known as Xiaohongshu) have decided to "wall off" US TikTok refugees fleeing to its service as the TikTok ban looms. The reason? The Chinese Communist Party (CCP) wants to prevent American influence from spreading to Chinese citizens. The ban is expected to be in place next week, while many believe that the influx of Americans to be temporary and just a reaction to the TikTok ban to move to another Chinese app. Many Chinese users are not happy with the influx as having "ruined" their ability to connect with "Chinese culture, Chinese values and Chinese news."

The U.S. Department of the Treasury's OFAC has sanctioned Yin Kecheng and Sichuan Juxinhe Network Technology Co. for their roles in a recent Treasury breach and espionage operations targeting U.S. telecommunications. BleepingComputer reports: "Yin Kecheng has been a cyber actor for over a decade and is affiliated with the People's Republic of China Ministry of State Security (MSS)," reads the Treasury's announcement. "Yin Kecheng was associated with the recent compromise of the Department of the Treasury's Departmental Offices network," says the agency. OFAC also announced sanctions against Sichuan Juxinhe Network Technology Co., a Chinese cybersecurity firm believed to be directly involved with the Salt Typhoon state hacker group. Salt Typhoon was recently linked to several breaches on major U.S. telecommunications and internet service providers to spy on confidential communications of high-profile targets. "Sichuan Juxinhe Network Technology Co., LTD. (Sichuan Juxinhe) had direct involvement in the exploitation of these U.S. telecommunication and internet service provider companies," the U.S. Treasury explains, adding that "the MSS has maintained strong ties with multiple computer network exploitation companies, including Sichuan Juxinhe." [...] The sanctions imposed on Kecheng and the Chinese cybersecurity firm under Executive Order (E.O.) 13694 block all property and financial assets located in the United States or are in the possession of U.S. entities, including banks, businesses, and individuals. Additionally, U.S. entities are prohibited from conducting any transactions with the sanctioned entities without OFAC's explicit authorization. It's worth noting that these sanctions come after OFAC sanctioned Beijing-based cybersecurity company Integrity Tech for its involvement in cyberattacks attributed to the Chinese state-sponsored Flax Typhoon hacking group. U.S. Treasury's announcement reiterates that the U.S. Department of State offers, through its Rewards for Justice program, up to $10,000,000 for information leading to uncovering the identity of hackers who have targeted the U.S. government or critical infrastructure in the country.

Russian Disinformation Campaigns Eluded Meta's Efforts To Block Them

17 janvier 2025 à 22:02
An anonymous reader quotes a report from the New York Times: A Russian organization linked to the Kremlin's covert influence campaigns posted more than 8,000 political advertisements on Facebook despite European and American restrictions barring companies from doing business with the organization, according to three organizations that track disinformation online. The Russian group, the Social Design Agency, evaded lax enforcement by Facebook to place an estimated $338,000 worth of ads aimed at European users over a period of 15 months that ended in October, even though the platform itself highlighted the threat, the three organizations said in a report released on Friday. The Social Design Agency has faced punitive sanctions in the European Union since 2023 and in the United States since April for spreading propaganda and disinformation to unsuspecting users on social media. The ad campaigns on Facebook raise "critical questions about the platform's compliance" with American and European laws, the report said. [...] The Social Design Agency is a public relations company in Moscow that, according to American and European officials, operates a sophisticated influence operation known as Doppelganger. Since 2022, Doppelganger has created cartoon memes and online clones of real news sites, like Le Monde and The Washington Post, to spread propaganda and disinformation, often about the war in Ukraine. [...] The organizations documenting the campaign -- Check First, a Finnish research company, along with Reset.Tech in London and AI Forensics in Paris -- focused on efforts to sway Facebook users in France, Germany, Poland and Italy. Doppelganger has been also linked to influence operations in the United States, Israel and other countries, but those are not included in the report's findings. [...] The researchers estimated that the ads resulted in more than 123,000 clicks by users and netted Meta at least $338,000 in the European Union alone. The researchers acknowledged that the figures provide only one, incomplete example of the Russian agency's efforts. In addition to propagating Russia's views on Ukraine, the agency posted ads in response to major news events, including theHamas attack on Israel on Oct. 7, 2023, and a terrorist attack in a Moscow suburb last March that killed 145 people. The ads would often appear within 48 hours, trying to shape public perceptions of events. After the Oct. 7 attacks, the ads pushed false claims that Ukraine sold weapons to Hamas. The ads reached more than 237,000 accounts over two to three days, "underscoring the operation's capacity to weaponize current events in support of geopolitical narratives," the researcher's report said.

Longtime Slashdot reader sfcat shares a report from the Associated Press: Hundreds of people were ordered to evacuate and part of Highway 1 in Northern California was closed when a major fire erupted Thursday afternoon at one of the world's largest battery storage plants. As the fire sent up towering flames and black smoke and showed no sign of easing by Thursday night, about 1,500 people were instructed to leave Moss Landing and the Elkhorn Slough area, The Mercury News reported. The Moss Landing Power Plant, located about 77 miles (about 124 kilometers) south of San Francisco, is owned by Texas-company Vistra Energy and contains tens of thousands of lithium batteries. The batteries are important for storing electricity from such renewable energy sources as solar energy, but if they go up in flames the blazes can be extremely difficult to put out. "There's no way to sugar coat it. This is a disaster, is what it is," Monterey County Supervisor Glenn Church told KSBW-TV. But he said he did not expect the fire to spread beyond the concrete building it was enclosed in. According to reports, the fire originated in the 300-megawatt Phase I section of the 750-megawatt facility, located on the site of a retired PG&E natural gas plant. It's unclear what caused the fire, but officials said a full investigation will begin after it's out. Thankfully, everyone at the site was evacuated safely. Videos and images of the fire can be found here.

Microsoft's $13 billion investment in OpenAI raises concerns that the tech giant could extend its dominance in cloud computing into the nascent AI market, the Federal Trade Commission said in a report released Friday. From a report: The commission said Microsoft's deal with OpenAI, as well as Amazon and Google's partnerships with AI company Anthropic, raise the risk that AI developers could be "fully acquired" by the tech giants in the future. "The FTC's report sheds light on how partnerships by big tech firms can create lock-in, deprive start-ups of key AI inputs, and reveal sensitive information that can undermine fair competition," FTC Chair Lina Khan said in a statement. The FTC has the power to open market studies to glean more information about industry trends. The findings can be used to inform future actions. It's unclear what the agency's new leadership under the Trump administration will do with the report.

An anonymous reader shares a report: FBI leaders have warned that they believe hackers who broke into AT&T's system last year stole months of their agents' call and text logs, setting off a race within the bureau to protect the identities of confidential informants, a document reviewed by Bloomberg News shows. FBI officials told agents across the country that details about their use on the telecom carrier's network were believed to be among the billions of records stolen, according to the document and interviews with a current and a former law enforcement official. They asked not to be named to discuss sensitive information. Data from all FBI devices under the bureau's AT&T service for public safety agencies were presumed taken, the document shows. The cache of hacked AT&T records didn't reveal the substance of communications but, according to the document, could link investigators to their secret sources. The data was believed to include agents' mobile phone numbers and the numbers with which they called and texted, the document shows. Records for calls and texts that weren't on the AT&T network, such as through encrypted messaging apps, weren't part of the stolen data.

Parcoursup : dans l’enfer des « algorithmes »

Que le sort puisse vous être favorable
Parcoursup : dans l’enfer des « algorithmes »

Pendant les prochains mois, un peu moins d’un million d’étudiants vont passer à la moulinette de Parcoursup. Une épreuve stressante pour les candidats et leur famille, avec une procédure pas toujours comprise. On vous explique comment ça fonctionne et les changements de cette année.

Parcoursup est la plateforme nationale de préinscription en première année de l’enseignement supérieur en France selon sa propre définition. Depuis 2018, c’est un passage quasi obligatoire pour la poursuite d’études post bac.

Le fonctionnement n’est pas toujours bien compris, parfois opaque – notamment au niveau des algorithmes, avec l’impression qu’une machine décide de notre vie – et avec des dérives de certains établissements. C’est aussi une source de stress importante pour les candidats (et les parents).

Le calendrier 2025 de Parcoursup

Depuis le 15 janvier, les étudiants peuvent s’inscrire et formuler des vœux, et ce, jusqu’au 13 mars. Les élèves ont ensuite jusqu’au 2 avril pour compléter leur dossier et confirmer leurs vœux. Ensuite, c’est parti pour une attente plus ou moins longue…

Le 2 juin 2025, c’est le « début de la phase principale d’admission », c’est-à-dire les premières réponses des formations (oui, non, liste d’attente). Le 11 juin débute la phase complémentaire avec la possibilité de formuler de nouveaux vœux. La phase principale d’admission se termine le 10 juillet et la phase complémentaire le 11 septembre pour ceux qui n’ont pas d’affectation en juillet.

Parcoursup est né des cendres d’APB

Pour comprendre la genèse de Parcoursup, il faut remonter à Admission Post-Bac (APB) lancé à la fin des années 2000. Les candidats y faisaient des vœux avec un classement par ordre de préférence, tandis que les établissements entraient le nombre de places disponibles et les conditions d’accès aux formations.

Ensuite, une machine passait ces éléments à la moulinette de l’algorithme de Gale-Shapley, dont le but est de résoudre un problème dit de « mariages stables ». Cet algorithme est capable de proposer une solution « stable » (dans le sens équitable) aux candidats, de sorte qu’aucun n’ait l’impression de se faire avoir.

Nous n’allons pas entrer dans les détails, mais on ne peut que vous conseiller de regarder l’excellente vidéo de David Louapre (chaine YouTube Science Étonnante) sur le sujet. Elle date de 2020, mais explique en images et avec des exemples l’algorithme de Gale-Shapley, les problèmes d’APB et les débuts de Parcoursup.

Deux gros problèmes ont causé la chute d’APB : les élèves pouvaient tenter de « craquer le code » et d’optimiser le classement de leurs vœux non pas en fonction de leurs envies, mais pour renforcer leurs chances. Il y avait aussi la gestion pour le moins hasardeuse de certaines formations sous tension, c’est-à-dire avec un grand nombre de candidats. « À la mi-juillet 2017, plus de 86 000 candidats, bacheliers de l’année ou en demande de réorientation, restaient sans proposition. L’autorisation d’un tirage au sort pour l’accès à certaines filières a achevé de gripper le système », expliquait Vie Publique en octobre 2017. La CNIL était même montée au créneau pour dénoncer cette pratique.

Parcoursup est ainsi né sur les cendres d’APB, avec deux principales différences : pas de classement des vœux par les candidats (même si les choses changent, nous y reviendrons) et pas de recours au tirage au sort. Le principe de l’algorithme de Gale-Shapley reste, mais les candidats doivent valider/classer leurs vœux au fil des semaines en fonction des propositions des formations. Conséquence directe : la procédure prend des semaines, avec des allers-retours entre les formations et les candidats, autour de Parcoursup qui joue les passe-plats.

Parcoursup, comment ça marche ?
