Google DeepMind's 'Leap Forward' in AI Could Unlock Secrets of Biology

Par : msmash
8 mai 2024 à 16:44
Researchers have hailed another "leap forward" for AI after Google DeepMind unveiled the latest version of its AlphaFold program, which can predict how proteins behave in the complex symphony of life. From a report: The breakthrough promises to shed fresh light on the biological machinery that underpins living organisms and drive breakthroughs in fields from antibiotics and cancer therapy to new materials and resilient crops. "It's a big milestone for us," said Demis Hassabis, the chief executive of Google DeepMind and the spin-off, Isomorphic Labs, which co-developed AlphaFold3. "Biology is a dynamic system and you have to understand how properties of biology emerge through the interactions between different molecules." Earlier versions of AlphaFold focused on predicting the 3D structures of 200m proteins, the building blocks of life, from their chemical constituents. Knowing what shape a protein takes is crucial because it determines how the protein will function -- or malfunction -- inside a living organism. AlphaFold3 was trained on a global database of 3D molecular structures and goes a step further by predicting how proteins will interact with the other molecules and ions they encounter. When asked to make a prediction, the program starts with a cloud of atoms and steadily reshapes it into the most accurate predicted structure. Writing in Nature, the researchers describe how AlphaFold3 can predict how proteins interact with other proteins, ions, strands of genetic code, and smaller molecules, such as those developed for medicines. In tests, the program's accuracy varied from 62% to 76%.

Apple Slammed By Users Over iPad Pro 'Crush' Ad

8 mai 2024 à 15:20
Less than 24 hours after Apple held a special event to unveil the new, record-thin (0.20 inch, the thinnest Apple device yet) iPad Pro with M4 chip inside, which the company says is optimized for AI, it is facing a loud and fast-spreading public backlash to one of its new marquee video advertisements promoting the device -- a spot called "Crush." VentureBeat: The video features a giant, industrial hydraulic press machine -- a device category famous for appearing in viral videos over the last decade-and-a-half -- literally pressing down upon and destroying dozens of other objects and creative instruments, from trumpets to cans of paint. The ad concludes with the press lifting to reveal these objects have somehow been transformed into a new iPad Pro. The metaphor and messaging is pretty obvious: the iPad Pro can subsume and replace all these older legacy instruments and technologies inside of it, and all in a more portable, sleek, and more powerful form factor than ever before. It's analogous to similar observations and advertisements other fans and creatives have made in the past about how PCs and smartphones replaced nearly all the individual gadgets -- stereo radios/boom boxes, journals, calculators, drawing pads, typewriters, video cameras -- of yore by offering many of their same core capabilities in a smaller, unified, more portable form factor. [...] People are revolted by the bluntness of Apple's metaphor, the destruction of beloved traditional instruments and objects which people hold in high esteem and affix intangible value to for their creative potential, and the overarching and perhaps unintentional messaging that Apple wants to literally flatten creativity and violently crush the creative tools of yesterday in favor of a multi-hundred dollar piece of luxury technology whose operating system and ecosystem of applications it tightly controls and restricts.

Déclaration officielle d'Intel sur les problèmes d'instabilité des CPU de 13ème et 14ème génération : Utilisez le Intel Default Settings et pas le Baseline Power

8 mai 2024 à 13:16

Cela fait maintenant quelques mois que les problèmes d'instabilité des CPU de 13ème et 14ème génération ont attiré l'attention de tous et Intel a finalement publié une déclaration officielle qui semble être un revirement total pour les fabricants de cartes mères qui ont déjà déployé leurs propres profils BIOS pour atténuer les problèmes. Dans la déclaration officielle fournie à HardwareLuxx, il est indiqué que bien que les fabricants de cartes mères déploient leurs propres profils BIOS Profil de base Intel ou Défaut de base, cela n'est pas le meilleur choix. Ces profils ne sont pas les mêmes que les 'Paramètres par défaut Intel' que la société recommande d'utiliser à la place des profils par défaut de base. La raison est assez simple, les anciens profils par défaut de base sont basés sur des directives de livraison de puissance plus anciennes fournies aux partenaires par Intel et, comme nous savons que les anciens profils ne garantissent pas aussi bien la stabilité, Intel a maintenant fourni aux partenaires fabricants de cartes mères de nouvelles recommandations qu'ils peuvent implémenter dans le BIOS.

Intel Issues Official Statement Regarding 14th and 13th Gen Instability, Recommends Intel Default Settings

8 mai 2024 à 14:05

Further to our last piece which we detailed Intel's issue to motherboard vendors to follow with stock power settings for Intel's 14th and 13th Gen Core series processors, Intel has now issued a follow-up statement to this. Over the last week or so, motherboard vendors quickly released firmware updates with a new profile called 'Intel Baseline', which motherboard vendors assumed would address the instability issues. 

As it turns out, Intel doesn't seem to accept this as technically, these Intel Baseline profiles are not to be confused with Intel's default specifications. This means that Intel's Baseline profiles seemingly give the impression that they are operating at default settings, hence the terminology 'baseline' used, but this still opens motherboard vendors to use their interpretations of MCE or Multi-Core Enhancement.

To clarify things for consumers, Intel has sent us the following statement:

Several motherboard manufacturers have released BIOS profiles labeled ‘Intel Baseline Profile’. However, these BIOS profiles are not the same as the 'Intel Default Settings' recommendations that Intel has recently shared with its partners regarding the instability issues reported on 13th and 14th gen K SKU processors.

 

These ‘Intel Baseline Profile’ BIOS settings appear to be based on power delivery guidance previously provided by Intel to manufacturers describing the various power delivery options for 13th and 14th Generation K SKU processors based on motherboard capabilities.

 

Intel is not recommending motherboard manufacturers to use ‘baseline’ power delivery settings on boards capable of higher values.

 

Intel’s recommended ‘Intel Default Settings’ are a combination of thermal and power delivery features along with a selection of possible power delivery profiles based on motherboard capabilities.

 

Intel recommends customers to implement the highest power delivery profile compatible with each individual motherboard design as noted in the table below:


Click to Enlarge Intel's Default Settings

What Intel's statement is effectively saying to consumers, is that users shouldn't be using the Baseline Power Delivery profiles which are offered by motherboard vendors through a plethora of firmware updates. Instead, Intel is recommending users opt for Intel Default Settings, which follows what the specific processor is rated for by Intel out of the box to achieve the clock speeds advertised, without users having to worry about firmware 'over' optimization which can cause instability as there have been many reports of happening.

Not only this, but the Intel Default settings offer a combination of thermal specifications and power capabilities, including voltage and frequency curve settings that apply to the capability of the motherboard used, and the power delivery equipped on the motherboard. At least for the most part, Intel is recommending users with 14th and 13th-Gen Core series K, KF, and KS SKUs that they do not recommend users opt in using the Baseline profiles offered by motherboard vendors.

Digesting the contrast between the two statements, the key differential is that Intel's priority is reducing the current going through the processor, which for both the 14th and 13th Gen Core series processors is a maximum of 400 A, even when using the Extreme profile. We know those motherboard vendors on their Z790 and Z690 motherboards opt for an unrestricted power profile, which is essentially 'unlimited' power and current to maximize performance at the cost of power consumption and heat, which does exacerbate problems and can lead to frequent bouts of instability, especially on high-intensity workloads.

Another variable Intel is recommending is that the AC Load Line must match the design target of the processor, with a maximum value of 1.1 mOhm, and that the DC Load Line must be equal to the AC Load Line; not above or below this recommendation for maximum stability. Intel also recommends that CEP, eTVB, C-states, TVB, and TVB Voltage Optimizations be active on the Extreme profile to ensure stability and performance are consistent.

Given Intel is essentially recommending users not to use what motherboard vendors are offering to fix, we agree that when motherboards come out of the box, they should operate at 'Default' settings until asked otherwise. We understand that motherboard vendors have the desire to showcase what they can do with their wares, features, and firmware, but ultimately there is some real lack of communication between Intel and its partners regarding this issue.

Following Intel's statement, they do recommend customers implement the highest power delivery profile which is compatible with the caliber of motherboard used by following the specification and design. According to Intel, this isn't open for interpretation despite what motherboard vendors have offered so far, and we do expect that there is likely to be more to come in this saga of constant developments regarding the instability issue.

AstraZeneca To Withdraw COVID Vaccine Globally as Demand Dips

AstraZeneca said on Tuesday it had initiated the worldwide withdrawal of its COVID-19 vaccine due to a "surplus of available updated vaccines" since the pandemic. From a report: The company also said it would proceed to withdraw the vaccine Vaxzevria's marketing authorizations within Europe. "As multiple, variant COVID-19 vaccines have since been developed there is a surplus of available updated vaccines," the company said, adding that this had led to a decline in demand for Vaxzevria, which is no longer being manufactured or supplied. According to media reports, the Anglo-Swedish drugmaker has previously admitted in court documents that the vaccine causes side-effects such as blood clots and low blood platelet counts.

US Eyes Curbs on China's Access To AI Software Behind Apps Like ChatGPT

Par : msmash
8 mai 2024 à 14:05
The Biden administration is poised to open up a new front in its effort to safeguard U.S. AI from China with preliminary plans to place guardrails around the most advanced AI models, the core software of artificial intelligence systems like ChatGPT, Reuters reported Wednesday. From the report: The Commerce Department is considering a new regulatory push to restrict the export of proprietary or closed source AI models, whose software and the data it is trained on are kept under wraps, three people familiar with the matter said. Any action would complement a series of measures put in place over the last two years to block the export of sophisticated AI chips to China in an effort to slow Beijing's development of the cutting edge technology for military purposes. Even so, it will be hard for regulators to keep pace with the industry's fast-moving developments. Currently, nothing is stopping U.S. AI giants like Microsoft-backed OpenAI, Alphabet's Google DeepMind and rival Anthropic, which have developed some of the most powerful closed source AI models, from selling them to almost anyone in the world without government oversight. Government and private sector researchers worry U.S. adversaries could use the models, which mine vast amounts of text and images to summarize information and generate content, to wage aggressive cyber attacks or even create potent biological weapons. To develop an export control on AI models, the sources said the U.S. may turn to a threshold contained in an AI executive order issued last October that is based on the amount of computing power it takes to train a model. When that level is reached, a developer must report its AI model development plans and provide test results to the Commerce Department.

US Revokes Intel, Qualcomm Licenses To Sell Chips To Huawei

Par : BeauHD
8 mai 2024 à 13:00
An anonymous reader quotes a report from MSN: The US has revoked licenses allowing Huawei to buy semiconductors from Qualcomm and Intel, according to people familiar with the matter, further tightening export restrictions against the Chinese telecom equipment maker. Withdrawal of the licenses affects US sales of chips for use in Huawei phones and laptops, according to the people, who discussed the move on condition of anonymity. House Foreign Affairs Committee Chairman Michael McCaul confirmed the administration's decision in an interview Tuesday. He said the move is key to preventing China from developing advanced AI. "It's blocking any chips sold to Huawei," said McCaul, a Texas Republican who was briefed about the license decisions for Intel and Qualcomm. "Those are two companies we've always worried about being a little too close to China." While the decision may not affect a significant volume of chips, it underscores the US government's determination to curtail China's access to a broad swathe of semiconductor technology. Officials are also considering sanctions against six Chinese firms that they suspect could supply chips to Huawei, which has been on a US trade restrictions list since 2019. [...] Qualcomm recently said that its business with Huawei is already limited and will soon shrink to nothing. It has been allowed to supply the Chinese company with chips that provide older 4G network connections. It's prohibited from selling ones that allow more advanced 5G access.
