New side-channel attack vulnerability found in Intel CPU

Security researchers have discovered a new side-channel attack vulnerability in Intel CPUs that could allow attackers to steal sensitive data from a computer system.

The vulnerability, dubbed "CacheOut", is similar to previous side-channel attacks such as Meltdown and Spectre, which were discovered in 2018. CacheOut allows attackers to access data that is supposed to be protected by Intel's SGX (Software Guard Extensions) technology.

SGX is a security feature that allows applications to create secure enclaves, or protected areas of memory, that are isolated from the rest of the system. This is designed to protect sensitive data such as encryption keys and passwords from being accessed by other applications or the operating system itself.

However, CacheOut allows attackers to bypass these protections and access data stored in SGX enclaves. This could potentially allow attackers to steal sensitive data such as passwords, encryption keys, and other confidential information.

Intel has released a security advisory acknowledging the vulnerability and has provided patches to mitigate the risk. However, researchers have noted that the patches may have a significant impact on system performance.

Users are advised to update their systems as soon as possible to protect against this vulnerability. Additionally, it is recommended to use strong passwords and encryption to further protect sensitive data.

As always, it is important to stay vigilant and keep up-to-date with the latest security news and updates to protect against emerging threats.

New Method 3D-Prints Metal Foam for Cheaper Oil Filters, Noise Isolation

A new method of 3D-printing metal foam has been developed that could lead to cheaper oil filters and better noise isolation in cars and other machinery.

The method, developed by researchers at the University of California, Irvine, involves using a 3D-printer to create a lattice structure out of metal powder. The lattice is then heated to a high temperature, causing the metal to melt and fuse together, creating a solid metal foam.

The resulting metal foam is lightweight and porous, making it ideal for use in oil filters and other applications where a high surface area is needed. The foam can also be used for noise isolation, as the porous structure helps to absorb sound waves.

One of the main advantages of this new method is that it is much cheaper than traditional methods of producing metal foam. The 3D-printing process is much faster and more efficient than other methods, and it also allows for greater control over the structure of the foam.

The researchers believe that this new method could have a significant impact on a wide range of industries, from automotive to aerospace. They are currently working on developing new applications for the metal foam, and are also exploring ways to improve the strength and durability of the material.

Overall, this new method of 3D-printing metal foam has the potential to revolutionize the way we think about manufacturing and engineering. It offers a cost-effective and efficient way to produce high-quality metal foam, which could have a wide range of applications in various industries.

Twitter Blue Ticks: Five Ways to Spot Misinformation Without Verified Accounts

Twitter blue ticks are a symbol of authenticity and credibility on the platform. However, not all accounts are verified, and it can be difficult to determine the accuracy of information shared by unverified accounts. Here are five ways to spot misinformation without relying on verified accounts:

1. Check the source: Look for reputable sources that have a history of accurate reporting. If the information is coming from a source that you have never heard of, it may be worth fact-checking before sharing.
2. Look for multiple sources: If a piece of information is only being reported by one source, it may not be accurate. Look for multiple sources reporting the same information to confirm its validity.
3. Check the date: Misinformation can often be spread by sharing old news stories or outdated information. Make sure to check the date of the information before sharing it.
4. Consider the tone: Misinformation can often be sensationalized or use extreme language to grab attention. If the tone of the information seems overly dramatic or exaggerated, it may be worth fact-checking before sharing.
5. Use fact-checking tools: There are several fact-checking tools available online that can help you determine the accuracy of information. Some popular fact-checking websites include Snopes, FactCheck.org, and PolitiFact.

While Twitter blue ticks can be a helpful indicator of credibility, it is important to remember that not all verified accounts are trustworthy, and not all unverified accounts are spreading misinformation. By using these five tips, you can help ensure that the information you share on Twitter is accurate and reliable.

Air-breathing cathode enhances conversion efficiency, durability of alkaline nickel-zinc batteries

Alkaline nickel-zinc batteries are a promising alternative to traditional lithium-ion batteries due to their high energy density and low cost. However, these batteries have been limited by their short cycle life and low conversion efficiency.

A team of researchers from the University of Waterloo has developed a new air-breathing cathode that can enhance the conversion efficiency and durability of alkaline nickel-zinc batteries. The cathode is made of a porous carbon material that allows oxygen from the air to enter the battery and react with the zinc electrode, which improves the battery's performance.

The researchers tested the new cathode in a prototype alkaline nickel-zinc battery and found that it had a conversion efficiency of 87%, which is significantly higher than the 70% efficiency of traditional alkaline nickel-zinc batteries. The new cathode also showed improved durability, with the battery maintaining 80% of its initial capacity after 1200 cycles.

The air-breathing cathode has the potential to make alkaline nickel-zinc batteries a more viable option for energy storage applications, such as electric vehicles and renewable energy systems. These batteries are also safer and more environmentally friendly than lithium-ion batteries, as they do not contain toxic or flammable materials.

The researchers are continuing to optimize the design of the air-breathing cathode and plan to test it in larger-scale batteries. They hope that their work will contribute to the development of more efficient and sustainable energy storage solutions.

UK Blocks Microsoft-Activision Gaming Deal, Biggest in Tech

The UK government has blocked Microsoft's proposed $68.7 billion acquisition of Activision Blizzard, the biggest deal in the tech industry. The decision was made by the Competition and Markets Authority (CMA), which said that the deal would have a negative impact on competition in the gaming industry.

The CMA said that the deal would give Microsoft too much control over the gaming industry, as it would own some of the biggest gaming franchises in the world, including Call of Duty, World of Warcraft, and Candy Crush. The CMA also said that the deal would reduce competition in the gaming industry, as Microsoft would be able to use its dominant position to raise prices and limit innovation.

Microsoft had argued that the deal would benefit gamers, as it would allow the company to invest more in gaming and create better games. However, the CMA said that there was no evidence to support this claim, and that the deal would actually harm gamers by reducing competition and limiting innovation.

The decision to block the deal is a blow to Microsoft, which had hoped to use the acquisition to strengthen its position in the gaming industry. However, the company said that it respected the decision of the CMA and would not appeal the ruling.

The gaming industry is one of the fastest-growing industries in the world, and the UK is home to some of the biggest gaming companies in the world, including Rockstar Games, which created the Grand Theft Auto franchise. The decision to block the Microsoft-Activision deal is likely to have a significant impact on the gaming industry in the UK and around the world.

The device, called an artificial synapse, is capable of processing information in a way that is similar to the way the brain processes sensory information.

What is an Artificial Synapse?

An artificial synapse is a device that mimics the function of a biological synapse, which is the junction between two neurons that allows them to communicate with each other. The artificial synapse is made up of a thin film of material that can change its resistance in response to an electrical signal. This change in resistance can be used to store and process information, just like the way the brain processes sensory information.

How Does it Work?

The artificial synapse works by using a process called spike-timing-dependent plasticity (STDP), which is a mechanism that allows neurons to change the strength of their connections based on the timing of their activity. The artificial synapse uses this mechanism to store and process information in a way that is similar to the way the brain processes sensory information.

What are the Applications?

The development of artificial synapse devices has many potential applications, including the development of more advanced artificial intelligence systems, the creation of more efficient and powerful computers, and the development of new medical treatments for neurological disorders.

Conclusion

The development of artificial synapse devices is a major breakthrough in the field of artificial intelligence and has the potential to revolutionize the way we process and store information. With further research and development, these devices could lead to the creation of more advanced and intelligent machines, as well as new treatments for neurological disorders.
