Investment Firm Ballistic Ventures Seeks $300 Million for New Cybersecurity Fund

Posted on November 17, 2023 by Igor Mitreski

Ballistic Ventures, a venture capital firm specializing in funding and nurturing cybersecurity startups, aims to raise up to $300 million for a new fund, according to a regulatory filing.

The San Francisco-based VC firm on Wednesday It has been submitted Working with U.S. Securities and Exchange Commission to raise $300 million for second fund – more than a year after launch Initial funds of equal amount In May 2022.

Ballistic spokeswoman Michelle Kincaid declined to comment on the filing when contacted by TechCrunch.

Targeting early-stage cybersecurity and cyber-related startups, ballistic ventures was co-founded by Kleiner Perkins general partner Ted Schlein, with three other general partners: Barmak Meftah, Jake Seid and Roger Thornton, and Mandiant founder Kevin Mandia as a strategic partner. The company also welcomes Derek Smith as strategic advisor and Agnes So as head of finance and operations.

Ballistic has backed more than a dozen startups to date, according to details available on the company’s website. Ballistic says it founded, operates and funds more than 90 cybersecurity companies. Previous investments the company has made include AuthMind, Oligo, and Nudge Security. The company also recently appointed Former U.S. National Cyber Secretary Chris Inglis and former CISA Chief of Staff Kirsten Todd will serve as advisors.

Cybersecurity investments so far this year are well below all-time highs.

Cybersecurity investments to date in 2023 are well below all-time highs. Venture funding to cybersecurity startups around the world fell more than 14% to $2.4 billion in the third quarter of 2023 from $2.8 billion in the same period last year, according to Pitchbook data shared with TechCrunch.

The number of deals completed in the most recent quarter also fell from 248 to 198.

Nevertheless, as the digital economy expands globally, cyber-attacks and online crimes are becoming more prevalent. Investors are also optimistic about the growth of cybersecurity startups and investments driven by significant advances in generative AI and cloud adoption.

Start-up founders allege that investors undermined their company with false user accusations in real life

Posted on November 16, 2023 by Igor Mitreski

IRL founders Abraham Shafi and Genrik Khachatryan are suing investors for intentionally sabotaging the company.

At its peak, IRL was poised to become an alternative way to host events for Gen Z, who were using Facebook less and less.

CEO Shafi said: Paused It was ordered by IRL in April to investigate allegations of misconduct. In June, IRL’s board of directors discovered after an investigation that 95% of the company’s 20 million users were fake. The founders now claim investors accounted for the 95% figure “as an excuse to shut down the company and return capital to shareholders.”

The lawsuit specifically names Goodwater Capital’s Chihua Qian, SoftBank’s Selina Dale, and Floodgate’s Mike Maples. From these investors his social calendar app raised more than $200 million and the valuation brought him $1.17 billion. Notably, SoftBank led IRL’s $170 million Series C round in 2021. Mr. Shafi and Mr. Khachatryan accused the investors of wanting to shut down the company because they were “trying to finance a large portion of the company’s $40 million in cash reserves.”

Although IRL is defunct, the remaining board members deny the founders’ claims.

“Immediately after the Shafi outage, IRL experienced a significant drop in the number of daily active users virtually overnight. This was not due to an outage,” IRL and its board said in a statement, and an IRL spokesperson said: Elliott Sloan shared with TechCrunch. The same report that found 95% of users are fake also cited “the existence of private groups with millions of duplicate names, irregular signatures from Hotmail, Yahoo email addresses, and burner email addresses. The statement said they also discovered “suspicious user behavior such as Said. Forensic reports show that his IP address from proxy-his servers was used extensively, with individual accounts cycling through his IP address and device type, which could be linked to user behavior. indicates that it is invalid.

“Based on this, and evidence of Shafi’s misappropriation of company funds and repeated obstruction of investigations, the board, after several months of consideration, has concluded that the company’s future prospects are unsustainable.” The statement concludes.

As of December of last year, the SEC. ongoing investigation IRL may have misled investors and violated securities laws.

IRL is just one once-hot start-up that has come under fire for potentially tampered metrics. Investors say Bolt and co-founder Ryan Breslow of the giant one-click checkout company misrepresented the company’s financials as it sought to raise $355 million in a Series E round. raised concerns and faced SEC investigation. But 15 months later, the SEC said the company likely not to be prosecuted. And earlier this year, the SEC charged student financial aid startup Frank with defrauding JPMorgan, which acquired the company for $175 million in 2021. JPMorgan has filed a lawsuit accusing Frank’s founder Charlie Jarvis of defrauding millions of customers to get her bank to buy her. company.

Bluesky, X’s competitor, reaches 2 million users; federation to launch in early next year

Posted on November 16, 2023 by Igor Mitreski

Bluesky is a company building a decentralized alternative to Twitter/X. announced It now has 2 million users, an increase of another 1 million since September, despite still being an invite-only app. It also revealed deadlines for other important goals, saying it plans to have a public web interface up and running by the end of this month and start federation by early next year.

The latter is one of the most important differentiators between Bluesky and X, as it allows Bluesky to function as a more open social network. This means it works more like Mastodon, where users can choose which servers to join and move their accounts around freely. This is what Bluesky today claims is “billionaire-proof” and criticizes Elon Musk’s ownership of Twitter, now known as X.

“Rather than being bound to the whims and black-box algorithms of private companies, you have the freedom to choose (and exit) at any time.” Explained in company blog post. “And wherever you go, your friends and relationships will be there too,” it states.

Similar to Mastodon, a decentralized service, federation allows anyone to run their own service and connect to other services running the same protocol. For Bluesky, this is done like this: AT protocol The company is also developing consumer services and mobile apps in parallel. But his other major decentralized social network, Mastodon, uses an established protocol, his ActivityPub, which has grown significantly in the months since Musk’s acquisition of Twitter. It is attracting attention.

Since then, other companies have adopted ActivityPub and Mastodon, including Mozilla, Flipboard, Medium, and Automattic (WordPress.com’s parent company). Unless Bluesky makes the AT protocol and ActivityPub interoperable in some way, there could be challenges regarding Bluesky’s ultimate reach. Bridging Maybe the two of you Technically It’s possible, but it’s more likely to be in the future, not in the near future.

Meanwhile, Bluesky is working to make its services more accessible, including launching a public web interface later this month. This will allow anyone to view his Bluesky posts, even if they don’t have an account. This could make the network more promising in terms of being a true competitor to X in breaking news and conversation, but it could expose Bluesky users’ posts to the outside world in ways they are not ready for. There is also. (This app currently does not have an option to set your profile to “private” like Twitter/X does. some users is not Happy about this. )

Despite its growth, Bluesky’s reluctance to drop its invite-only status and open its network to more users has allowed other competitors of X to gain a foothold. Last month, for example, Meta CEO Mark Zuckerberg announced that Instagram Threads, an alternative to X, had just under 100 million monthly active users. He believes he can reach 1 billion users in the next few years. Threads also plans to interoperate with ActivityPub in the future.

Bluesky’s announcement follows Threads’ rapid release of features to make the app more competitive with X, including a chronological feed, support for displaying likes, search, and (free) Includes an edit button, web version, voting, GIF support, and more. , topic tags, and soon a developer API. Mastodon also took advantage of the opportunity presented by the Twitter acquisition and launched an easier-to-use version of its service in September of this year. However, Mastodon currently has 1.6 million monthly active usersHowever, it is much smaller than a thread.

In addition to today’s news, Mr. Bluesky also provides mobile push notifications, shareable user lists, email verification, advanced feed and thread settings for sorting and filtering posts, a media tab in user profiles, and a user profile for your own users. We also mentioned other recently released features, such as a Likes tab for profiles. , the suggestions below, and various accessibility improvements.

Bluesky started life as a Twitter project under Jack Dorsey, but the company was spun off from Twitter. $13 million How to start research and development. Mr. Dorsey sits on its board of directors. This year, the company raised an $8 million seed round led by Neo to further its development and transformed from a public benefit LLC to a public benefit C Corp.

Debut of 440-mile range All-electric Lucid Gravity SUV

Posted on November 16, 2023 by Igor Mitreski

EV maker Lucid has completed the long-awaited Gravity. It’s an all-electric three-row SUV with the range to leave your Tesla Model X, Fisker Ocean, or Rivian R1S behind at a charging station.

The importance of Lucid Gravity, and more appropriately the recognition it receives, is essential for EV manufacturers. The company’s first EV, the Lucid Air sedan, has been well received. But demand has been weak this year, forcing automakers to cut prices and lower production estimates for this year.

Gravity could help Lucid regain its footing in the increasingly competitive EV industry. Of course, Lucid has to actually start the vehicle.clear delay In this respect, sedans and SUVs are no different. The company originally aimed to start manufacturing the Gravity SUV at the end of 2023, but in August the production date was changed to the end of 2024.

Lucid Gravity Basics

Lucid boasts that this EV “heralds the dawn of a new era for electric SUVs.” This tone has an explanation. As the sale of Lucid’s first vehicle (a luxury sedan called the Air) Not as good as that, its future now depends on whether Gravity can actually become a force in the EV market. But this is a new era for Lucid. And the all-electric SUV designed by the company has some notable attributes, including a rugged, low-slung design with a sport tail at the rear, all of which contribute to a drag coefficient of 0.24. I am. Its aerodynamic design is one element of his that contributes to battery life. Lucid also claims the vehicle accelerates from his 0 to 60 in less than 3.5 seconds. one more second longer than what Tesla claims for the Model X plaid.

Lucid Gravity features a compact powertrain with an EV motor and 900-volt electrical architecture. Payload capacity exceeds 1,500 lbs, plus 6,000 lbs. The company claims that the towing capacity is not sufficient. Lucid estimates Gravity’s range to be over 440 miles. Lucid boss Peter Rawlinson said in a statement that the expected range would be possible “with just over half the battery packs of our battery-hungry competitors.” If Lucid performs as suggested in real-world conditions, it will be the longest-range electric SUV on the market.

The vehicle appears to be able to charge like a Tesla, giving it 200 miles of range in about 15 minutes on a fast charger. The company says the seven-seat SUV will have a starting price of less than $80,000. If history is any guide, there will be plenty of add-ons and trim levels that far exceed that price point.

Inside the clear gravity

Inside, the SUV features a 34-inch curved OLED screen that floats above a redesigned steering wheel. Like the Air, the Lucid enhances the interior touches.

Of note is the seven-seater configuration and console that slides open for additional storage. Lucid said these sliding second-row seats, combined with an integrated convenient table, provide an “enhanced backseat experience.”

The company says the second- and third-row rear seats both fold flat for a total of more than 112 cubic feet of usable cargo space.

Unity’s aim to provide developers with ethical and useful generative AI through Muse

Posted on November 16, 2023 by Igor Mitreski

Unity is joining other companies in providing users with generative AI tools, but ensuring that those tools (unlike some) are built on a foundation that is not based on theft. I have been careful to check. Muse, a new suite of AI-powered tools, starts with texture and sprite generation and gradually moves into animation and coding as it matures.

The company announced these features at the Unite conference in San Francisco, along with Unity 6, the next big version of its cloud-based platform and its engine. After a turbulent few months that saw major product plans completely scrapped and a CEO ousted, you’re probably looking to get back to business as usual if possible.

Unity has traditionally positioned itself as a champion for small developers who lack the resources to adopt broader development platforms like rival Unreal. Therefore, the use of AI tools can be considered a useful addition for a developer who cannot afford to spend days creating, for example, 32 slightly different wooden wall textures in high resolution. can.

There are many tools out there to help you create and modify assets like this, but it’s often desirable to be able to say “make something more like it” without leaving your main development environment. The simpler your workflow, the more you can do without worrying about details like formatting or siled resources.

AI assets are also often used in prototyping, where things like artifacts and slightly wonky quality (which these days are common regardless of model) don’t really matter. However, illustrating your gameplay concept with original, well-made art rather than stock sprites or free sample 3D models can make the difference in communicating your vision to publishers and investors.

Examples of sprites and textures generated by Unity’s Muse.

Another new AI feature, Sentis, is a little harder to understand. “It enables developers to bring complex AI data models into the Unity runtime to create new gameplay experiences and features,” Unity’s press release states. So it’s kind of his BYO model, with some features built in, and it’s currently in open beta.

AI for animation and movement is in development and will be added next year. These highly specialized scripting and design processes can greatly benefit from generative first drafts or multiplicative helpers.

Image credits: unity

The Unity team emphasized that a big part of this release is to ensure that these tools are not overshadowed by future IP infringement lawsuits. Image generators like Stable Diffusion are fun to play with, but they’re built using assets from artists who never agreed to have their work taken and regurgitated.

“To provide usable output that is safe, responsible, and respectful of the copyrights of other creators, we challenged ourselves to innovate the training techniques for the AI models that power Muse’s sprite and texture generation.” says a blog post on responsible AI. Techniques associated with presentations.

The company said it used a completely custom model trained with images owned or licensed by Unity. However, they essentially used stable diffusion to generate a larger synthetic dataset from the small, carefully selected datasets they had assembled.

Image credits: unity

For example, this wood wall texture may be rendered with several variations and color types using a stable diffusion model, but no new content will be added. At least that’s how it’s described to work. But as a result, new datasets are not only based on responsibly sourced data, but also one step removed from it, making it less likely that a particular artist or style will be duplicated.

Although this approach is more secure, Unity admitted that the quality of the initial models it was providing was reduced. However, as mentioned above, the actual quality of the generated assets is not necessarily important.

Unity Muse costs $30 per month as a standalone product. We’re sure you’ll soon hear from the community about whether this product is worth its price.

Enhanced Google Maps now includes additional social features for planning outings with friends

Posted on November 15, 2023 by Igor Mitreski

Google Maps get some new updates, includes social features designed to help people plan and collaborate with friends. The navigation platform also adds improved transit directions and emoji responses.

New social features are designed to take planning from group chats to Google Maps. The platform is updating its Lists feature to make it easier for people to share locations, make plans with friends, vote on group activities, and more. With this new feature, you can share locations in Maps with your friends, then create collaboration lists and start planning hangouts. Everyone in the group can add locations they want to visit and vote using emojis like hearts and thumbs up.

Image credits: Google

Google says the new feature will allow users to plan outings from start to finish within the Maps app. For example, you can invite your friends, make a list, and decide on all the activities you want to do this winter. Everyone can add activities that interest them, like ice skating at a specific rink or checking out the Holiday Market. Once people start voting, everyone will be able to see which activities are the most popular.

The new update will roll out globally on Android and iOS in the coming weeks.

When it comes to transportation improvements, Google Maps now makes it easy to see the best route to your destination based on factors such as ETA, number of connections, and trip length. We’ve also added the option to customize your route based on the type of transportation you want to use, or choose a route that requires minimal walking.

Plus, you’ll know exactly where the station entrances and exits are, which side of the street they’re on, and a clear walking route to and from the station. These updates will help ensure you’re on the right train in the right direction.

The transportation update will begin rolling out on Android and iOS in the coming weeks.

Google Maps also adds emoji reactions to photos, videos, and reviews. If you can’t find an emoji that sums up your feelings, you can sometimes create a mashup reaction like this: emoji kitchen. Emoji reactions begin rolling out globally today on Android and iOS.

The Process of a ‘Bouncing’ Comet Spreading Life Across the Galaxy

Posted on November 15, 2023 by Igor Mitreski

Researchers at the University of Cambridge have discovered how comets can deliver the molecular building blocks of life to planets in our galaxy, particularly those in the “pea-in-a-pod” system, where the planets orbit each other closely. It was demonstrated that

Cambridge researchers have proposed that comets could carry the building blocks of life to other planets, especially in the “pea-in-a-pod” system. Their findings suggest that these molecules can survive on planets with close orbiting neighbors, providing new insights into the search for extraterrestrial life.

How did the molecules that make up life originate on Earth? One long-standing theory is that they may have been transported by comets. Now, researchers from the University of Cambridge have shown how comets can deposit similar building blocks on other planets in the galaxy.

The role of Comet Speed and the “Peas in a Pod” system

To transport organic material, comets must travel relatively slowly, at speeds of less than 15 kilometers per second. At higher speeds, critical molecules cannot survive. The speed and temperature of the impact causes the molecules to break apart.

The most likely place for a comet to travel at a reasonable speed is in a “pea in a pod” system, where groups of planets orbit closely together. In such systems, comets can essentially pass or “bounce” from one planet’s orbit to another, slowing them down.

If the velocity is slow enough, the comet will hit the planet’s surface, releasing intact molecules that researchers believe are precursors to life. The results were announced on November 15th. Proceedings of the Royal Society A suggests that if the arrival of comets is important for the origin of life, such systems would be promising places to look for life outside the solar system.

Comet: carrier of prebiotic molecules

Comets are known to contain various building blocks of life known as prebiotic molecules. For example, a sample of asteroid Ryugu analyzed in 2022 showed that the asteroid was delivered intact. amino acid and vitamin B3. Comets also contain large amounts of hydrogen cyanide (HCN), another important prebiotic molecule. HCN has strong carbon-nitrogen bonds, making it highly resistant to high temperatures. This means that it can survive and remain intact even if it enters the atmosphere.

Lead author Richard Anslow, from the Cambridge Institute of Astronomy, said: “We’re constantly learning more about the atmospheres of exoplanets, so we’re wondering whether there are planets out there where complex molecules could be transported by comets. I wanted to find out.” “It’s possible that the molecules that brought life to Earth came from comets, and the same could be true for other planets in our galaxy.”

The researchers do not claim that comets are necessary for the origin of life on Earth or other planets, but instead place limits on the types of planets to which complex molecules such as HCN can be successfully transported by comets. I was thinking about it.

Comet path and influence on the solar system

Most of the comets in our solar system are located outside of Earth’s orbit. Neptune,So-called kuiper belt. When comets and other Kuiper Belt Objects (KBOs) collide, they can be pushed toward the Sun by Neptune’s gravity and eventually pulled into the Sun. Jupitergravity. Some of these comets pass through the asteroid belt and enter the inner solar system.

“Earth is currently the only example of a planet with life, so we wanted to test our theory on a planet similar to ours,” Anslow said. “What kind of comet, moving at what speed, could deliver intact prebiotic molecules?”

Using various mathematical modeling techniques, the researchers determined that it is possible for comets to carry precursor molecules throughout their lives, but only in certain scenarios. For a planet to orbit a star similar to our Sun, the planet must have a low mass, and it is beneficial for the planet to be in a close orbit to other planets in the system. The researchers found that nearby planets in close orbits are much more important for planets around low-mass stars, whose typical velocities are much higher.

In such a system, a comet could be pulled in by the gravity of one planet and pass by another before colliding with it. If this “comet pass” occurs enough times, the comet’s velocity will be slow enough that some prebiotic molecules will be able to survive atmospheric entry.

“In these dense systems, each planet has a chance to interact with and capture the comet,” Anslow said. “This mechanism could be how prebiotic molecules reach the planet.”

For planets orbiting low-mass stars like M dwarfs, complex molecules are more difficult to transport by comets, especially if the planet’s density is loose. Rocky planets in these systems are also exposed to higher velocity collisions, which can pose unique challenges for life on these planets.

Implications for the search for extraterrestrial life

Researchers say their results could help determine where to look for life outside the solar system.

“It’s interesting that we can start to identify the types of systems that can be used to test different origin scenarios,” Anslow said. “This is another way of looking at the great work already being done on Earth. What molecular pathways gave rise to the wide variety of life we see around us? Are there other planets with similar pathways? These are exciting times, as we can combine advances in astronomy and chemistry to study some of the most fundamental questions.”

Comets are the most likely carriers of life’s essential building blocks to planets in clusters

Posted on November 15, 2023 by Igor Mitreski

Nearby neighboring worlds can slow down the comet enough to allow the building blocks of life to survive

It may be easiest to deliver materials for life to neighboring planets. Comets can carry many of the key building blocks of life, such as amino acids and other organic compounds, but their ability to deliver those building blocks to a particular planet depends on the configuration of their broader systems. It may depend.

There are several ideas about how the ingredients for life began on Earth, but the common idea is that a comet hit the Earth and organic molecules were deposited here. But comets tend to travel through space at extremely high speeds, and if they hit a planet at more than about 20 kilometers per second, the chances of their important compounds surviving the impact are almost zero.

Richard Anslow Researchers at the University of Cambridge ran a series of simulations to investigate how planetary systems can slow down comets and reduce their impact velocity enough to preserve these compounds. In ideal conditions, a slow impact would leave behind a type of prebiotic soup called a comet pond within the impact crater.

They discovered that there are two types of systems that can slow down a comet by 5 to 10 kilometers per second. One is a system with relatively massive stars, where everything tends to orbit slightly. For planets that are slow and have several planets spaced closely together like peas in a pod, the comet could weave between them and lose speed over time. there is.

“The best planetary systems are on relatively low-mass planets like Earth, around high-mass stars similar to the Sun but perhaps even more massive, and close enough for other rocky planets to pass through.” “It would be in a planetary system that has comets around it,” Anslow said.

He said that if astronomers eventually detect signs of life on other planets, simply examining the overall system configuration could help them understand how it got there. and that it could advance our limited understanding of how life formed. Earth.

Morpheus Space’s new space mission design platform is user-friendly for everyone.

Posted on November 15, 2023 by Igor Mitreski

Space propulsion developer Morpheus Space today announced its first software product, a mission simulation and design platform called Journey.

Morpheus product manager Jim Gianakopoulos said in a recent interview (and in a recent product walkthrough) that the product has been in the works for nearly two years. This was born out of the typical thruster sales process. Customers come to Morpheus to ask if the startup’s lineup of electric propulsion systems can meet their mission requirements. However, the process is highly technical, fragmented, and manual.

“We found that to be a deterrent,” Giannakopoulos said. “Just by giving the user a place of control to actually simulate the entire mission themselves, analyze and refine it, and see what kind of propulsion system fits, it empowers them. Masu. [their] needs. “

Journey aggregates all the data typically spread across Excel sheets, Python, and other systems and quickly spits out mission and system designs. The software allows customers to input measurements, operations, launch dates, and other requirements for a custom system. The software is designed to be easy to use, even for non-technical users, with templates for common attributes such as satellite size.

In particular, the Journey platform does more than just match customers to Morpheus’ unique propulsion system. Depending on mission requirements, we may also recommend third-party chemical propulsion systems and various subsystems such as attitude determination, control systems, and communications.

The platform’s first product is called Preliminary Mission Design (PMD), and the company also plans to roll out a higher-fidelity Advanced Mission Design (AMD). The platform is designed to support customers from mission conception through end-of-orbit operations.

Morpheus has five to six early customers who are using PMD products to inform early mission and system designs. AMD plans to release a closed beta within the next two weeks. Morpheus was founded in 2018 with offices in Germany and El Segundo, California. Last September, the company closed its $28 million Series A round led by Alpine Space Ventures.

Blue Sky: A comprehensive guide to Twitter alternatives

Posted on November 14, 2023 by Igor Mitreski

Is the grass greener next door? I’m not sure, but I’m sure the sky is bluer.

It’s been over a year since Elon Musk bought Twitter leading people to set up shop on alternative platforms. mastodon, post, pebble (already Shutter operation) and spill are presented as potential replacements, but few apart from the meta thread have achieved the growth rate that Bluesky has achieved. Bluesky is still invite-only in beta, but the hype is growing as more people visit the site. As you can see from apps like Clubhouse., the hype may not last forever. Meanwhile, Blue Sky has over 1 million users, according to Blue Sky’s Rose Wang. The app saw 8,300 first-time installs per day on average since its release in July 2023, but no substantive updates regarding download data have been released since then. And when Mr. Musk makes less-than-favorable changes to his X, Mr. Bluesky often checks record usage. During the launch of the site, many people asked for invitation codes (which were being bought on eBay) and it became more accessible as more people joined the app. Here we answer the most common questions about Bluesky Social.

What is Blue Sky? Bluesky is a decentralized social app conceptualized by former Twitter CEO Jack Dorsey and developed in parallel with Twitter. This social network features a Twitter-like user interface with algorithmic selection, federated design, and community-specific moderation. Bluesky uses open source frameworks built in-house, specifically the AT protocol, which means that people outside the company get transparency into how the company is built and what is being developed. Dorsey introduced the Bluesky project in 2019, when he was still Twitter CEO. At the time, he said Twitter would fund “a small, independent team of up to five open source architects, engineers, and designers” responsible for building decentralized standards for social media, adding that he said the goal is for Twitter itself to adopt this standard. But that was before Elon Musk acquired the platform, and as of late 2022, Bluesky is completely divorced from Twitter. Mr. Dorsey even used Mr. Bluesky to express his dismay with Mr. Musk’s leadership. Twitter is funding a small, independent team of up to five open source architects, engineers, and designers to develop open, decentralized standards for social media. The goal is for Twitter to eventually become a client of this standard. 🧵

How do I use Blue Sky? Once invited, users create a handle represented as @username.bsky.social and a display name that is prominently displayed in bold. If you feel like it, you can turn your domain name into your username. For example, his Darrell Etherington from TechCrunch is known on Bluesky as @etherington.com. The app itself functions a lot like basic Twitter, with the plus button allowing you to create 256-character posts. Posts can also include photos. The post itself can be replied to, retweeted, liked, reported from the Miscellaneous menu, shared to other apps via the iOS share sheet, or copied as text. Search for and follow others to see their latest updates on your Home timeline. Previously, the Bluesky app featured popular posts in the “What’s Hot” feed. That feed is then replaced by an algorithm, Personalized Discover feed, not just trending content. There’s also a Discover tab at the bottom center of the app’s navigation, offering more Who to Follow suggestions and a running feed of recently posted Bluesky updates.

How do I invite someone to Bluesky? New users will receive one invitation code for every two weeks they use the Bluesky app. The company monitors your social graph and further provides invitation codes to share with users, who have invited trusted participants. In the long term, Bluesky says the company considers the invitation code system to be part of the open source tools it is building to help server administrators manage and manage their communities.

Who is in Blue Sky? By early July 2023, instagram thread launched, Bluesky surpasses 1 million downloads across iOS and Android. App was officially released in September 2023 with 1 million users. High-profile figures have moved to Blue Sky, including Rep. Alexandria Ocasio-Cortez (D-N.Y.), Neil Gaiman, and Chelsea Manning. It is also home to organizations and journalists such as. X expulsion NPR, Taylor Lorenz and Jake Tapper.

Does Bluesky work like Twitter? In many ways, yes. However, Bluesky still lacks advanced tools such as DM and adding accounts to lists. In addition, Twitter supports ActivityPub and in Bluesky originally began as a project convened in 2019 when Jack Dorsey was CEO of Twitter. However, the social app has been an independent company since its founding in 2021.

Is Blue Sky free? Yes, but access is currently invite-only.

How does Blue Sky make money? Bluesky’s goal is to find other means to sustain the network outside of advertising through paid services, and to remain free for end users. On July 5, Bluesky announced an additional seed round of funding and a paid service that provides custom domains to end users who want to have their own domain as a handle for the service.

Is Bluesky decentralized? Yes. Bluesky’s team is developing a decentralized AT protocol that Bluesky is built on top of. In the beta stage, users can only join his bsky.social network, but Bluesky is planned to be federated. This means that an infinite number of independently operated communities can exist within an open source network. So if a developer other than Bluesky builds their own new social app using his AT protocol, Bluesky users can jump to the new app and port over their existing followers, handles, and data.

Is Blue Sky safe? In October 2023, Blue Sky added email verification. This is part of a larger effort to improve security and authentication of accounts on our network. This addition is an important step forward in making Bluesky more competitive against larger networks like X with more robust security controls.

Is Bluesky customizable? Yes. In May, Bluesky released custom algorithms, or what the company calls “custom feeds.” Custom His Feed allows users to subscribe to multiple different algorithms that showcase different types of posts that users want to see.

DeepMind AI outperforms top weather forecasts, with one caveat

Posted on November 14, 2023 by Igor Mitreski

Will the AI tell me if I need an umbrella?

AI company Google DeepMind says AI can more accurately predict the weather 10 days out than current state-of-the-art simulations, but meteorologists are still trying to build weather models based on actual physical principles. It warns against abandoning and relying solely on patterns in the data. Expose the shortcomings of AI approaches.

Existing weather forecasts are based on mathematical models, which use physics and powerful supercomputers to definitively predict what will happen in the future. These models have gradually become more accurate by adding more details, but this requires more calculations, more powerful computers, and higher energy demands.

Rémi Lam and his colleagues at Google DeepMind took a different approach. The company’s GraphCast AI model is trained on his 40 years of historical weather data from satellites, radar, and ground-based measurements to identify patterns that even Google DeepMind can’t understand. “As with many machine learning AI models, it’s not that easy to interpret how the model works,” Lamb says.

To make the predictions, actual weather measurements taken at two points six hours apart from more than one million locations around the globe are used to predict the weather six hours into the future. These predictions can be used as input for another round that predicts another 6 hours into the future.

DeepMind researchers carried out this process using data Produces a 10-day forecast from the European Center for Medium-Range Weather Forecasts (ECMWF). They say it outperformed ECMWF’s “gold standard” High Resolution Forecasting (HRES) by providing more accurate forecasts on more than 90 per cent of the data points tested. At some altitudes, this accuracy increased to 99.7%.

Matthew Chantry He, who worked with Google DeepMind at ECMWF, said his organization had previously seen AI as a tool to complement existing mathematical models, but in the past 18 months it has seen a shift in the way AI can actually provide predictions on its own. He said that he has become able to do so.

“We at ECMWF believe this is a very exciting technology that has the potential not only to reduce energy costs when making forecasts, but also to improve them. Creating a reliable operational product “Probably more work is needed, but this is likely the beginning of a revolution in the way weather forecasts are made, and this is our assessment,” he says. According to Google DeepMind, using GraphCast to make a 10-day forecast takes him less than a minute on a high-end PC, but with HRES it can take several hours on a supercomputer.

But some meteorologists are wary of trusting weather forecasting to AI. Ian Renfrew According to researchers at the University of East Anglia in the UK, GraphCast currently lack the ability to marshal data into its own starting state, a process known as data assimilation. In traditional predictions, this data is carefully incorporated into simulations after thorough checks on physics and chemistry calculations to ensure accuracy and consistency. Currently, GraphCast must use a starting state prepared in the same way by ECMWF’s own tools.

“Google won’t be doing weather forecasts any time soon because they can’t assimilate the data,” Renfrew said. “And data assimilation is typically one-half to two-thirds of the computation time for these forecasting systems.”

He says there are also concerns about completely abandoning deterministic models based on chemistry and physics and relying solely on AI output.

“Even if you have the best predictive model in the world, what’s the point if the public doesn’t trust you and you don’t take action? We ordered the evacuation of 30 miles of Florida’s coastline. “If nothing happens, it will blow away the trust that has been built over decades,” he says. “The advantage of a deterministic model is that you can investigate it. If you get a bad prediction, you can investigate why that prediction is bad and target those aspects for improvement.”

Civitai, a generative AI content marketplace with millions of users, receives backing from Andreessen Horowitz

Posted on November 14, 2023 by Igor Mitreski

A community that has a large following is stable diffusion, particularly among those experimenting with new AI technologies and creating their own models. Now, there is a platform called Chibitai, a startup that allows members to share their AI image models and content with other enthusiasts. The name “Chibitai” is a word play on “Civitas,” meaning community. Chibitai CEO Justin Maier recognized the need for such a platform after working on web development projects at Microsoft. He saw the potential for creating AI-generated images and posted them on platforms like Reddit and Discord, but felt the need for a centralized community to share and discover AI image models.

Chibitai became the go-to place for sharing AI models and images in 2023 and has since grown to over 3 million registered users and receives about 12-13 million unique visitors every month. The company has even raised $5.1 million in funding from Andreessen Horowitz (a16z) in June 2023.

The platform allows users to upload images to create their own AI image models, and with each image generated, metadata is provided that includes details such as prompts and resources used. However, concerns have been raised about artists’ work being used without consent to train AI models, which Chibitai is working to address by allowing artists to flag resources they believe are using their work. Additionally, there are also concerns about non-consensual pornographic AI images being shared on the platform, which the company is working to address.

In the future, Chibitai aims to expand to other modalities beyond AI image models and to create a consumer-facing mobile app that will act as a repository for AI images. The company also plans to enable users to monetize their creations, but for now, everything on the site is free to use.

Major Banks Foresee Significant Interest Rate Reductions – Stay Updated with Blockchain News, Expert Opinions, and Job Opportunities in the Financial Sector.

Posted on November 14, 2023 by Igor Mitreski

Strategists at UBS investment bank expect a significant interest rate cut by the US central bank, which is seen as bullish for Bitcoin. UBS said falling inflation could prompt the U.S. central bank (Federal Reserve) to start cutting interest rates as early as March. This development is perceived as very positive for Bitcoin, especially considering recent economic indicators.

US inflation slows significantly, eliminating bets on further Fed rate hikes

Recent data reveals slowing U.S. inflation, extinguishing hopes for further rate hikes from the Federal Reserve. The consumer price index stalled in October, with the core index rising 0.2%. Those numbers have led traders to push back when they expect the U.S. Federal Reserve to make its first move to cut interest rates.

This change in expectations is consistent with UBS’s prediction of a significant interest rate cut, creating a supportive backdrop for Bitcoin in the following ways:

Reduced opportunity cost: As traditional interest rates decline and expectations of further rate hikes fade, the opportunity cost of holding Bitcoin also decreases. This could make Bitcoin more attractive to investors looking for alternative assets.

Inflation hedge: As inflation slows, investors could turn to assets like Bitcoin, which some see as a hedge against inflation. The scarcity and decentralized nature of cryptocurrencies could make them an attractive store of value in an environment of reduced inflationary pressures.

Market speculation: Revisions to the Fed’s rate hike outlook could spark speculative activity in financial markets. Bitcoin’s higher return potential and its characteristic volatility may attract traders looking for opportunities in a changing interest rate landscape.

Macroeconomic uncertainty: Recent economic data, coupled with revised Fed rate hike expectations, may signal broader economic uncertainty. In times like these, Bitcoin’s role as a decentralized and non-traditional asset is likely to become more prominent as investors seek to escape market volatility.

This combination of factors, with the potential for increased demand and favorable market sentiment, is reinforcing Bitcoin’s positive outlook.

12 Billion Years Ago, JWST Uncovers Secrets of Star-Forming Galaxies

Posted on November 14, 2023 by Igor Mitreski

Thanks to the James Webb Space Telescope, astronomers discover that most early galaxies from about 12 billion years ago had more glowing gas than stars due to interactions with neighboring galaxies. I was able to.

This groundbreaking result provides new insights into the evolution of galaxies and the early Universe, and highlights the transformative impact of JWST on astrophysics.

New images from the James Webb Space Telescope (JWST) have helped Australian astronomers uncover the secrets of how infant galaxies began a burst of star formation in the very early universe .Some early galaxies were rich in gas that shined brighter than emerging stars. In a new study, astronomers have discovered just how prevalent these bright galaxies were about 12 billion years ago. Images from JWST show that nearly 90% of galaxies in the early Universe had this glowing gas, creating so-called “extreme emission line features. An image of a distant polar emission galaxy.

“The stars in these young galaxies were amazing, producing enough radiation to excite the gas around them. This gas, in turn, shined even brighter than the stars themselves.” said Dr. Anshu Gupta, Curtin University Node of the ARC Center for Three-Dimensional All-Sky Astrophysics (ASTRO 3D) and the International Radio Astronomy Research Center.Iqral), lead author of the paper describing this finding. “Until now, it has been difficult to understand how these galaxies are able to accumulate so much gas. Our discovery suggests that each of these galaxies had at least one neighboring galaxy. This suggests that interactions between these galaxies cool the gas and trigger intense star formation episodes, resulting in this extreme luminescence property.” Progress in observing galaxies in the early universe

This discovery is an example of the unparalleled clarity the JWST telescope provides in studying the early universe.

“The quality of data from the James Webb Telescope is exceptional,” says Dr. Gupta. “It has the depth and resolution necessary to observe the surroundings and neighboring galaxies of early galaxies, when the universe was just 2 billion years old. We were able to confirm that there are significant differences in the number of neighboring galaxies among galaxies that do not.”

Until now, we’ve struggled to get clear images of galaxies whose universe is about 2 billion years old. Since many stars had not yet formed, there were far fewer galaxies to focus on, making the task even more difficult.“Before JWST, we could only get pictures of really huge galaxies, most of which were in very dense galaxy clusters, making them difficult to study,” says Dr. Gupta. “With the technology available at the time, it was not possible to observe 95% of the galaxies used in this study. His Webb telescope revolutionized our research.

Checking previous assumptions
The discovery proved an earlier assumption, said fellow author Tran, associate director of ASTRO 3D and the Harvard University and Smithsonian Center for Astrophysics. “We suspected that these extreme galaxies were signposts of intense interactions in the early universe, but only with JWST’s keen eye could we confirm our hunch.” she says.

The study is based on data obtained as part of the JWST Advanced Deep Extragacular Survey (JADES) survey, which uses deep infrared imaging and multi-object spectroscopy to explore the universe for the earliest galaxies. It paves the way for further insights. “What’s really interesting about this study is that we see similarities in emission lines between the first galaxies and galaxies that formed more recently and are easier to measure. It means we now have more ways to answer difficult questions about the early Universe,” said second author Ravi Jaiswal, PhD student at Curtin University/ICRAR and ASTRO 3D.

“This research is at the heart of the work of our Galaxy Evolution Programme. Understanding what earlier galaxies looked like will help us answer questions about the origins of the elements that make up all of our daily life on Earth. We can,” said Professor Emma Ryan-Weber, ASTRO 3D Director.

Obskur’s Character Creator and Marketplace Simplifies VTuber Experience

Posted on November 14, 2023 by Igor Mitreski

To stream as them My mysterious alter ego is a VTuber named Mai. M41H41, typically had to juggle at least four to seven different programs. However, doing everything at once was not only mentally exhausting, but also taxed the computer and could cause it to overheat in the process. If the program crashes, you have to destroy the characters to fix it. “In many cases, you don’t actually need to use all the programs,” Mai told TechCrunch during a Discord call. “So I literally told the community, ‘Sorry, you can’t like, throw videos, chat interactive videos today. Because we literally can’t do it right now.” ” VTuber A portmanteau of “virtual YouTuber,” who streams as a 2D or 3D model rather than showing his or her actual face. This burgeoning genre has produced some highly successful streamers, but the barrier to entry has been high due to the upfront costs and technical skills required to stream as an animated character. Obscur, an all-in-one broadcast application, wants to make VTubers more accessible by allowing users to create 3D models and interactive environments without any technical skills. The company premiered several new features at TwitchCon, including Character Creator, which was officially released last week. Obskur’s broadcast software essentially combines multiple different programs into his one platform, which can be easily integrated with Twitch. This is a big attraction for her VTubers like Mai. Obskur’s Character Creator and user-generated content marketplace is particularly unique in the VTuber space. Character Creator allows users to customize his 3D model by choosing free hairstyle, facial features, and body type. Users can adjust features to change their shape and size using sliders, and select feature colors from a color wheel. For further customization, users can browse an integrated marketplace where artists sell ready-made models and his 3D assets such as costumes and interactive backgrounds. “It needs to be advanced enough that people can create a character that’s so unique that they feel like, ‘This is me and this is my brand.’ But it also needs to be easy enough that they don’t need to know anything. ” Obskur co-founder Andranik Aslanyan told TechCrunch. “It’s like you don’t have to understand rigging, modeling, textures, etc. Just select a few options and it feels like a video game. If you can play The Sims, our application You should be able to use it.” Image credits: Provided by Obscur Mai says she started using Obksur regularly after testing the demo at TwitchCon. Previously, I used up to 12 applications to run streams. One is for running models, who often have flowing seafoam-colored hair, pink moth-like antennae, and ruffled black tops; It is meant to improve body tracking. Additional software was required to perform basic animation. For example, something as simple as a VTuber making a model cry or flirting with a subscriber by bouncing her chest can involve technical subtleties that viewers rarely see behind the scenes. . Mai has to use third-party programs for her chat interactions, such as being able to throw things at viewers or sprinkle flower petals, and also says that she has to use third-party programs to make those interactions a part of her Twitch earnings. It was necessary to use additional third-party software to integrate with the features. She also needed a program to upload models into her 3D backgrounds, ranging from a basic living room to an extraterrestrial planet. “And that’s before you even think about the type of content you’ll create that day,” Mai continued. “And you need to learn how each of them works as an application on its own, but also how it works as an application in conjunction with other applications you’re running. There are a variety of models. There were probably 10 to 12 applications that I downloaded for the part.” Next is cost. When Mai first became interested in her VTuber last year, she tried to create her own models by drawing with a mouse using her free software VRoid Studio. They said it was impossible and “looked all sorts of awful.” They ended up paying another artist about $100 to $120 (the industry’s “absolute rock bottom”) to model. A high quality She 2D model can cost thousands of dollars or more, depending on the quality of the original artwork, custom She mesh and textures, and various animations. Even 3D models that are less complex to animate are still expensive to commission. Additional assets such as new costumes, hairstyles, and backgrounds are expensive and difficult to source. While many artists focus on custom commissions, others sell preset assets on Etsy, Patreon, or other online marketplaces scattered across the internet. Some large marketplaces, like Booth, are “absolute monsters in and of themselves,” Mai said, as they are offered entirely in Japanese. “In that case, you have to download them and hope they’re in the right file format. If you don’t speak the language, no one will understand,” Mai said. Aslanyan pointed out that chat interactions are not only cumbersome to use, but also difficult to look at. On Twitch, users can purchase bit, prices start at $3.00 for 300 pieces and go up to $308 for 25,000 pieces. Twitch pays streamers 1 cent per Bit, so streamers typically offer special perks to viewers who spend Bits while streaming. VTubers often encourage their viewers to consume Bits by providing certain interactive features. A viewer can, for example, “throw” objects such as electronic money to her VTuber by spending 100 bits, and change her outfit by spending 1,000 bits. Streamers needed to get into character and engage with their viewers while manually triggering interactions in the third-party software they were using. Image credits: Provided by Obscur Obskur’s Twitch extensions and apps make features like viewer interaction more seamless for both streamers and viewers. The app allows streamers to determine different stages of interaction, which are automatically triggered when a viewer consumes a Bit. Obskur receives the standard 20% developer share set by Twitch. Aslanyan hopes that by making the process more seamless, monetization opportunities will become more accessible for streamers. “The idea behind it is to give viewers a reason to spend some money, because if you look at the return on bits compared to things like subscriptions and direct donations, it’s on the lower side. ” Aslanian said. “The reason is that there is no real incentive to donate to Bit.” It may be easier for streamers to monetize their work, but do artists risk losing their commissions? VTuber 2D and 3D design has grown into a digital cottage industry since 2020, with many artists looking to make full use of it. Time relies on commissions for its income. Neither Mai nor Aslanyan are worried about Obscur’s Character Creator pushing out artists. Instead, they said, the platform’s user-generated marketplace creates opportunities for artists to expand their clientele. Mai described Character Creator as a “baseline” opportunity for complete beginners to step into her VTuber career without paying a fortune or learning complex animations. “I think there’s still a lot of desire for specific art styles with specific designs that are unique only to individual artists. They’re still doing that craft in other mediums, and a lot of artists are moving into this field. “I mainly work in Obscur because the marketplace allows you to make money from the assets you’ve already created,” Mai said. Additionally, if streamers want to use more complex and highly specialized models for their streams, they can import commissioned works into Obskur. Image credits: Provided by Obscur Image credits: Courtesy of Obxul Aslanyan added that Obskur considered feedback from artists when designing Character Creator. An artist known as the art director of Obscur. art gunis known for designing the model for Ironmouse, one of North America’s most popular VTubers. According to Aslanyan, she oversaw the development of the character creator and also helped launch the marketplace. “From my point of view as a creator, the market size is expanding,” Aslanyan continued. “The basics are one-to-one. In our case, we can create a cool jacket, and then in the marketplace people have almost instantaneous access to the character, and we can sell that jacket many times over, and we’re able to sell that jacket many times over. You can potentially generate more revenue than spending months creating a jacket for a single character. It’s more of a scale business than…

McLaren Healthcare discloses ransomware attack resulting in 2.2 million patient data theft

Posted on November 13, 2023 by Igor Mitreski

Michigan-based McLaren Healthcare has confirmed that the sensitive personal and health information of 2.2 million patients was compromised in a cyberattack earlier this year. Later, a ransomware gang took credit for the cyberattack.

in New Data Breach Notification McLaren said in a filing with the Maine attorney general that hackers breached its systems over a three-week period from July 28 to Aug. 23, before the health care company noticed it a week later on Aug. 31. He said that he had done so.

According to McLaren, the hackers accessed a wealth of medical information, including patients’ names, dates of birth, and social security numbers, as well as invoices, billing and diagnostic information, prescription and drug details, and information about diagnostic results and treatments. It is said that he did. Medicare and Medicaid patient information was also collected.

McLaren is a healthcare provider with 13 hospitals in Michigan and approximately 28,000 employees. McLaren, which touts cost-efficiency efforts on its website, made more than $6 billion in revenue in 2022.

News of the incident broke in October when the Alphv ransomware group (also known as BlackCat) claimed responsibility for the cyberattack, claiming that millions of patients’ personal information was stolen. day to day after a cyber attack Michigan Attorney General Dana Nessel warned residents that the breach “could potentially impact a large number of patients.”

TechCrunch has reviewed several screenshots posted by ransomware gangs on dark web leak sites, which show the company’s password manager, internal financial statements, some employee information, and patient-related information such as names, addresses, and phone numbers. Confirmed that it showed access to spreadsheets of personal and health information. , social security number, and diagnostic information.

Alphv/BlackCat claimed in the post that the gang had been in contact with McLaren representatives, but provided no evidence of this.

Contacted via email, McLaren spokesperson David Jones declined to comment beyond the company’s official statement or answer our questions about the incident. A spokesperson declined to say whether the company had received any payment requests or paid the hackers. McLaren’s chief information security officer, George Goble, declined to make him available for an interview.

Revival of Startup Valuations Possible with AI Automation

Posted on November 13, 2023 by Igor Mitreski

AI technology is According to , it helps startups become leaner and more cost efficient. Latest report from Battery Ventures. Conversely, Battery expects low-burn startups to become even more valuable if growth rates remain attractive.

Exchange explores startups, markets, and money.

Read it every morning on TechCrunch+ or get The Exchange newsletter every Saturday.

That’s an interesting paper. When we think of AI from a startup perspective, we tend to think about what AI-powered software startups themselves build. If we turn the question of what AI software does, for Battery sees a future where startups are worth many times their revenue. This could allow more emerging technology companies to receive venture-backed or full-stop support, and increase the chances that existing startups can grow to their previous valuations.

The issue is the amount of software revenue. The story of a rebound in tech stock prices from 2021’s market gluts is a familiar one by now, and startups can’t get any hotter than they once were when money was cheap and plentiful. The same view applies.

But what’s the point of a profitable startup if it can’t grow quickly? Seems unlikely. So what venture investors want above all, and founders do too, is a world where every dollar of revenue a startup generates is worth more. This situation will help the venture math pencil to draw more neatly.

It’s much easier to invest in a cash-burning startup when the revenue you’re building is worth, say, $9 instead of $6. Or $4.

Traditional Finance’s Increasing Involvement in Bitcoin Revealed – Blockchain News, Analysis, Interviews, Opportunities

Posted on November 13, 2023 by Igor Mitreski

Last week, Bitcoin (BTC) rose 5.9% to close at around $37,000 compared to the previous week’s closing price of $35,000. This week has seen solid price movements, with BTC seeing fluctuations with prices increasing continuously every day from Monday to Friday. The highest trading price was observed on Thursday, reaching nearly $38,000. After this peak, prices declined slightly and stabilized at around $37,000 from Friday through the weekend.

BTC dominance, which measures Bitcoin’s market capitalization relative to the overall digital asset market, fell for the second consecutive week, settling at around 52.3%. This corresponds to a decrease of 0.7% compared to the previous week and highlights the continued dispersion of liquidity among more speculative assets. This is characteristic of a phase in which investors express confidence in the market and engage in riskier trades.

Trading activity continues to soar, with cumulative daily volume on centralized exchanges reaching $31.4 billion, calculated on a seven-day moving average. This figure is the highest since the end of March and reaffirms that the recent uptrend is driven by strong trading activity.

A notable aspect is the heavy involvement of traditional finance in the recent uptrend. Chicago Mercantile Exchange (CME)’s BTC open interest exceeded 100,000 contracts for the first time, surpassing Binance and becoming the top exchange in terms of BTC open interest. This strong presence of traditional financial investors is evident in the Grayscale Bitcoin Trust (GBTC) discount rate, which has now narrowed to 10.3%, its lowest level since August 2021. .

The increase in traditional financial activity related to BTC confirms the confidence market investors currently have regarding the approval of a future BTC spot ETF. It is important to note that the first final decision deadline from the SEC on the 21Shares BTC Spot application is scheduled for January 10, 2024. Presumably, to avoid giving issuers a first-mover advantage, the SEC will make a final decision to approve or deny all applications by this date. Additionally, applications for digital asset spot ETFs continue, with recent news including BlackRock’s ETH Spot ETF following Grayscale’s decision to apply for conversion from Ethereum Grayscale Trust (ETHE) to ETH Spot ETF. It has been revealed that he has applied for an ETF. How many weeks ago?

The surge in prices and trading activity, particularly through traditional financial channels, coupled with a consistent decline in the GBTC discount and significant net inflows observed in ETPs underlying digital assets, has led investors in the market to bet on approval. It suggests that Securing approval from the SEC is likely to attract significant investment from traditional finance, bringing an influx of new investors and potentially strengthening digital assets and pushing them into a more recognized asset class. . Conversely, a rejection would likely cause a short-term economic downturn, given the general expectation in favor of approval and the subsequent positioning of market participants, which will be heavily influenced by this expectation.

The Rise of Inversion Art as the Y Combinator of the Art World

Posted on November 12, 2023 by Igor Mitreski

for many startups, qualifying for an accelerator program like Y Combinator or TechStars is like winning the golden ticket to Willy Wonka’s Chocolate Factory. Accelerators offer a wealth of opportunities that can make the difference between a great idea that fails to reach its potential and a great idea that leads to an IPO.

We’re used to seeing accelerators work for companies that disrupt travel, payment processing, and cloud storage, but what if that model could work outside the confines of the VC factory? Artists What if you could use a little investment, a lot of mentoring and hands-on support, a ton of referrals, and a ton of faith to help you in your career?

That’s exactly right inverted art Trying to.

“Y Combinator changed my life,” Inversion Art co-founder Joey Flores told TechCrunch. “I am very grateful for this program and thought it would be great to do something like that for artists.”

Mr. Flores is a Y Combinator alumnus. Music Marketing Platform EarBits It graduated from the program in 2010 and was sold in 2015. Although Flores is not a professional artist, art is a very important part of his life, and a chance comment by a VC in a 2020 conversation set him on the path to finding an artist. It’s his way of supporting artists who have the drive and passion to make art a lifelong career, but need help to achieve it. As part of his research, he connected with co-founder Jonathan Neal and together they seek to change the way artists find success and recognition.

“Artists have always relied on others, such as collectors, museums and galleries, to build their careers and define success,” Neal said. “In our opinion, we are the first organization to actually sit at the same table with artists in all of their negotiations and activities and truly help them define success for themselves.”

The microbiome may be linked to memory loss in Alzheimer’s disease, new study finds

Posted on November 12, 2023 by Igor Mitreski

A groundbreaking study proves that Alzheimer’s disease symptoms can be induced in healthy animals through gut microbiome transmission, highlighting the gut-brain connection and suggesting early treatment and treatment of Alzheimer’s disease. New avenues for personalized interventions have been opened.

Researchers have discovered a link between the gut microbiome and gut bacteria. Alzheimer’s disease disease.

For the first time, research has demonstrated that symptoms of Alzheimer’s disease can be transmitted to healthy young organisms through the gut microbiome, confirming its role in Alzheimer’s disease.

The research was led by Professor Yvonne Nolan from APC Microbiome Ireland, the world’s leading SFI-funded research center based at University College Cork (UCC), and Professor Yvonne Nolan from UCC’s Department of Anatomy and Neuroscience. Professor Sandrine Thure, King’s College London, and Dr. Annamaria Cattaneo, IRCCS Fatebenefratelli, Italy.

This study confirms that the gut microbiome is emerging as an important research target for Alzheimer’s disease, given its sensitivity to lifestyle and environmental influences.

was announced on brainThis study shows that memory impairment in Alzheimer’s patients can be transferred to younger animals through gut microbiota transplantation.

Alzheimer’s disease, memory impairment, gut microbiome

Patients with Alzheimer’s disease had greater abundance of pro-inflammatory bacteria in their fecal samples, and these changes were directly correlated with the patients’ cognitive status.

Professor Yvonne Nolan said: “The memory test we investigated relies on the growth of new neurons in the hippocampal region of the brain. Animals with the gut bacteria of Alzheimer’s patients produced fewer new neurons and had impaired memory. I found out that it is true.”

“Alzheimer’s patients are typically diagnosed at or after the onset of cognitive symptoms, which may be too late, at least with current treatments. “Understanding the role of gut bacteria could pave the way for the development of new treatments and even personalized interventions,” Professor Nolan said.

Implications for treatment strategies and research collaborations

Alzheimer’s disease is the most common cause of dementia and is a general term for memory loss and other cognitive impairments severe enough to interfere with daily life. As the population ages, one in three people born today could develop Alzheimer’s disease. Funded by Science Foundation Ireland, scientists at UCC are leading the way in healthy brain aging by investigating how the gut microbiome responds to lifestyle influences such as diet and exercise. We are working to develop strategies to accelerate and advance the treatment of Alzheimer’s disease.

Professor Sandrine Thuret, Professor of Neuroscience at King’s College London and one of the study’s senior authors, said: ‘Alzheimer’s disease is an insidious disease and there is still no effective treatment. , represents an important advance in the understanding of this disease, confirming that the composition of our gut microbiota is causally linked to the development of the disease. This collaboration will help future research in this field. We hope that this will lead to potential advances in therapeutic interventions.”

Professor. John F. Cryan, vice president of research and innovation at UCC, who also worked on the study, said: He conducts research into related diseases such as Alzheimer’s disease, and with UCC he recognizes APC Microbiome Ireland as a leading institution in microbiome and brain health research. This research is consistent with our UCC Futures Framework and the University’s strategic plans in the areas of food, microbiome, health and, soon to be launched, Future Aging and Brain Sciences. “

Equipped with a miniature camera, the TRISAT-R CubeSat captured unique images of the Earth from 6,000 km, contributing to ESA’s research on medium-Earth orbit and digital imaging effects.

Partially shadowed Earth in the distance as seen from orbit at an altitude of 6,000 km (3,700 miles). This unusual image was obtained using a very small camera. It measures just 2 mm (0.08 inches), about the size of the end of a 20 euro cent (or US nickel). This is part of a small-scale technology experiment carried out on his shoebox-sized TRISAT-R CubeSat at ESA.

Iztok Kramberger, TRISAT-R project manager at the University of Maribor, explains: “This tiny camera, less than 2 cubic millimeters in size, captured images of an object of about 1 trillion cubic kilometers – our beautiful Earth – from thousands of kilometers away.”

A CubeSat made from three standardized 10 cm (4 inch) boxes, Trisat R This is Slovenia’s second space mission, with Europe’s first Vega-C launch last year reaching the relatively harsh environment of medium-Earth orbit at an altitude of 6,000 km (3,700 miles). The mission’s orbit passes through the core of the ionosphere (the electrically active layer of Earth’s atmosphere) and the inner Van Allen radiation belt.

The side cover size of TRISAT-R CubeSat is 10×10 cm. In the center you can see the photodiode (the white part in the middle) and the camera (the small black dot next to the diode and directly above the image). In the center of the camera, you can see a 2 x 2 mm camera lens with a 120 degree field of view. The lens is made from clear, radiation-resistant borosilicate glass and is attached directly to the image sensor below, providing 320 x 320 pixels.Credit: University of Maribor

This will enable TRISAT-R to test a range of radiation detection payloads. In addition, the TRISAT-R team mounted his two miniature cameras with lenses made of clear borosilicate glass directly onto a 320×320 pixel image sensor to provide limited radiation resistance. Ta.

Dr. Cranberger added: “These highly miniaturized cameras are not intended to perform ground imagery, so the resulting images of the Earth are very low resolution. Also, the TRISAT-R satellite uses magnetorque for attitude control. accurate pointing is difficult to achieve.

“Our main interest was in capturing an example of the ‘black sun effect’, which is common in terrestrial digital image processing, where pixel oversaturation can cause very bright areas to appear dark. We were successful in these investigations and were fortunate to be able to obtain images like this one. ”

ESA supported the manufacturing, assembly and testing of TRISAT-R through the ‘Fly’ element of the Integrated Support Technology Program, opening up on-orbit demonstration opportunities for European companies.

Located in a unique and challenging orbit, TRISAT-R’s commissioning phase is scheduled to conclude later this month, including 16 months of successful on-orbit operations.

Elon Musk Biopic to be Directed by Darren Aronofsky, According to Sources

Posted on November 11, 2023 by Igor Mitreski

An Elon Musk biopic is being produced at New York-based studio A24 and is being directed by “Black Swan” director Darren Aronofsky, according to sources.

A24 has secured the rights to the biopic of the world’s richest man, Walter Isaacson, the people said, adding that the Musk biopic will be produced by Aronofsky’s production company Protozoa Pictures.

“I’m glad Darren is doing it. He’s one of the best players,” Musk said in an X post on Friday.

The studio previously worked with the director on the film The Whale, starring Brendan Fraser, which won Academy Awards for Best Actor, Best Makeup and Best Hairstyling.

A24 received 18 Academy Award nominations for six films this year, ranking second behind entertainment giant Walt Disney.

Isaacson’s book about Apple co-founder Steve Jobs was made into a film of the same name by Universal in 2015, starring Irish actor Michael Fassbender as the late tech tycoon.

A book about Mr. Musk was released in September by book publishing giant Simon & Schuster, which is owned by private equity firm KKR.

The person told Reuters the deal was highly competitive, with top studios and filmmakers also competing.

Mr. Musk is the head of rocket maker and satellite communications company SpaceX, the head of Tesla, the world’s most valuable carmaker, and the head of tunnel construction company The Boring Company and brain chip company Neuralink.

The billionaire acquired social media platform X (formerly known as Twitter) for $44 billion last year after a six-month acquisition spree.

The merger of quantum biology and AI fueled genome editing advancements

Posted on November 11, 2023 by Igor Mitreski

Scientists at Oak Ridge National Laboratory have utilized quantum biology and explainable artificial intelligence to advance CRISPR Cas9 technology for genome editing in microorganisms. This breakthrough has enabled more precise genetic modification of microorganisms, opening up possibilities for the production of renewable fuels and chemicals. The research at Oak Ridge National Laboratory has significantly improved the efficiency of CRISPR Cas9 genome editing in microorganisms and contributed to renewable energy development.

CRISPR is a powerful tool for bioengineering, used to modify the genetic code to improve the performance of organisms or correct mutations. ORNL scientists developed a method to improve the accuracy of the CRISPR Cas9 gene editing tool used to modify microorganisms for the production of renewable fuels and chemicals. They have leveraged their expertise in quantum biology, artificial intelligence, and synthetic biology to achieve this.

To improve the modeling and design of guide RNAs, ORNL scientists sought to better understand what is happening at the most fundamental level in the cell nucleus, where genetic material is stored. They turned to quantum biology to study how electronic structure affects the chemical properties and interactions of nucleotides, such as DNA and RNA.

Furthermore, scientists at ORNL have built an explainable artificial intelligence model called iterated random forest, which has been used to train the model on a dataset of about 50,000 guide RNAs targeting the genome of Escherichia coli. This model has provided important features regarding the nucleotides that allow for better selection of guide RNAs.

Improving the CRISPR Cas9 model provides scientists with a high-throughput pipeline for linking genotype to phenotype in functional genomics. This research will impact efforts at the ORNL-led Center for Bioenergy Innovation (CBI), such as improving bioenergy feedstock plants and bacterial fermentation of biomass.

The results of this research significantly improve the prediction of guide RNAs. This represents an exciting advance toward understanding how avoid ‘mistakes’ and improving the ability to use CRISPR tools to predictively modify the DNA of more organisms. The study was funded by SEED SFA and CBI, part of the DOE Office of Science’s Biological and Environmental Research Program, ORNL’s Laboratory-Directed Research and Development Program, and OLCF and Compute’s High Performance Computing Resources and Data Environment for Science, both supported by the Office of Science.

UK News: Government Urges Targeted Vaccination for Individuals Most Vulnerable to Gonorrhea and Monkeypox

Posted on November 11, 2023 by Igor Mitreski

British scientists are urging the government to implement routine vaccines for those most susceptible to monkeypox and gonorrhea, marking the world’s first immunization program against the latter. The Joint Committee on Vaccination and Immunization (JCVI) has recommended to Rishi Sunak that both programs be offered opportunistically to those who need it most.

Professor Andrew Pollard, Chair of the JCVI, expressed, “The UK’s gonorrhea prevention program is a world-first and is expected to significantly reduce gonorrhea levels, which are currently at record highs. In addition, we recommend implementing routine monkeypox vaccinations to prevent a recurrence of the outbreaks seen in early 2022. Both vaccines should be offered to those at highest risk.”

The JCVI also advises that recommended vaccination programs against gonorrhea should primarily target gay and bisexual men and other men who have sex with men, who are at higher risk of contracting the disease. This comes in light of a 50.3% increase in gonorrhea diagnoses in 2022 compared to 2021, totaling 82,592 cases, according to Health and Safety Executive sexually transmitted infection (STI) statistics. Additionally, the number of gonorrhea cases in the UK last year was reported to be up by more than a fifth from pre-pandemic levels.

Greg Fell, chairman of the Association of Public Health Officers, told Sky News: “The recent rise in sexually transmitted infections such as gonorrhea is extremely worrying and today’s advice from the JCVI is undoubtedly a prudent course of action. However, this increase in numbers is also a result of more people visiting clinics and other diagnostic services for testing, which has led to higher demand for sexual health services.”

“As we said in June, we are concerned that the current level of funding for sexual health services provided by public health grants in England will not be able to meet this increase in demand. The new vaccination program will therefore be planned with this in mind and backed by appropriate funding and resources to ensure that existing services remain intact and people can be vaccinated in a timely and dignified manner as needed.”

YC-Powered Voice API Platform Empowers Productivity App Bots with Super-Powerful Pivot

Posted on November 11, 2023 by Igor Mitreski

Calendar apps are essential to productivity, but it’s difficult to differentiate them enough from their core use cases to sustain growth. Powered by Y Combinator super powerfulan AI-powered meeting note-taking tool that does not require bot recording, has overcome this obstacle and is currently Vapian API provider, makes it easy for anyone to create natural, voice-based, AI-powered assistants.

Superpowered was founded in 2020 by Jordan Deersley and Nikhil Gupta. But Dearsley said after three years of work, the team wanted to work on a more challenging product. Superpowered is profitable, the startup said, and the company has no intention of shutting down its first product and is in the process of hiring someone to run it. Y Combinator announced in June that more than 10,000 people use the product each week, but the company did not provide updated numbers.

To date, Superpowered/Vapi has raised $2.1 in seed money from investors including Kleiner Perkins and Abstract Ventures.

Pivot to Vapi

The company offers Vapi as an API that allows developers to create bots using only a prompt and putting it behind a phone number. Additionally, SDK integration is also provided, allowing developers to embed bots on their websites and mobile apps.

Dearsley told TechCrunch via email that the idea to build Vapi stemmed from a personal problem. He moved to San Francisco and began to miss his friends and family in different time zones. He built his AI bot that connects to the other party’s phone number to have a conversation with someone to organize their thoughts.

“I liked it, but I was constantly annoyed by how unnatural it was. It didn’t feel like talking to a person. The audio cut out, it took a long time to respond, and when I was talking it would interrupt me. ” he said.

“So I kept working on it and went for walks with it. Eventually, we fell in love with this conversation problem. It’s really hard to make something feel human. Voice assistants. today It’s clunky and turn-based, so I wanted to create something with a human touch. ”

Technically, Vapi is currently integrating a number of third-party APIs to build a robust voice conversation platform. For example, we use solutions from Twilio for phone calls, Deepgram for transcription, Daily for audio streaming, and OpenAI for responses. PlayHT For text reading.

ScaleConvo, a 2024 YC Winter Batch startup, is already using Vapi to launch conversational bots for sales teams and property management companies. However, Vapi did not reveal other customers.The company publishes his API Current Vapi Phone and Vapi Web products.

Vapi challenges

According to Magnus Revan, former Gartner analyst and chief product officer at multimodal conversation startup Openstream.ai, one of the startup’s biggest challenges is reducing latency.

“OpenAI models take between 2 and 10 seconds to generate a response. On the phone, the gold standard is 700 milliseconds between when the user finishes speaking and when the ‘bot’ begins speaking. And with capable models (high parameter count open source models like LLaMA2 70B) it is very difficult to achieve sub-second latencies,” he says.

Currently, Vapi’s latency is between 1.2 and 2 seconds depending on various factors. Dearsley expects that Vapi’s own efforts and improvements to his OpenAI will bring latency down to below a second for him in the next month.

Mohamed Musbah, an angel investor at Vapi, also said that the startup’s solution will be improved by overall advances in APIs.

“As OpenAI and other companies improve their models, Vapi’s platform will become more powerful, with a better knowledge base, code execution capabilities, and a larger context window. “As demand grows, Vapi’s focus on solving the biggest friction areas in voice communications will be a strength for the company,” he said.

However, this puts the responsibility on improving other solutions, not Vapi itself. Dearsley said the reliance on other APIs will make Vapi less defensive if large companies start moving into the space. But the team said it has an advantage in that it has built the infrastructure to handle thousands of calls simultaneously. Dearsley emphasized that with the general availability of Vapi’s web and phone APIs, the team will also look to build proprietary models for his audio-to-audio solutions.

NASA’s Webb and Hubble team up to capture the most vivid image of the universe

Posted on November 10, 2023 by Igor Mitreski

This panchromatic view of galaxy cluster MACS0416 was created by combining infrared observations from NASA’s James Webb Space Telescope with visible-light data from NASA’s Hubble Space Telescope. Credits: NASA, ESA, CSA, STScI, Jose M. Diego (IFCA), Jordan CJ D’Silva (UWA), Anton M. Koekemoer (STScI), Jake Summers (ASU), Rogier Windhorst (ASU), Haojing Yan ( University of Missouri)https://chat.openai.com/c/de5c3def-7d31-49b0-bd44-3d61675a3ae5

The result is a vivid landscape of the galaxy and more than a dozen newly discovered time-changing objects.

When the two flagship observatories come together, they reveal a wealth of new details that are only possible through their combined power. Webb and Hubble collaborated on studying MACS0416, a galaxy cluster about 4.3 billion light-years from Earth. Combining these data yields a prismatic panorama of blue and red. These colors provide clues to the galaxy’s distance. While the images themselves are surprising, researchers are already using these observations to fuel new scientific discoveries, such as identifying gravitationally expanded supernovae and ordinary stars.

This side-by-side comparison of galaxy cluster MACS0416 seen in optical light from the Hubble Space Telescope (left) and infrared light from the James Webb Space Telescope (right) reveals different details. Both images show hundreds of galaxies, but the Webb image shows galaxies that are invisible or only barely visible in the Hubble image. This is because Webb’s infrared vision can detect galaxies that are too far away or covered in dust to be seen by Hubble. (Light from distant galaxies is redshifted due to the expansion of the universe.) Webb’s total exposure time was about 22 hours, while the exposure time of the Hubble image was his 122 hours.

NASA’s Webb Space Telescope and Hubble Space Telescope combine to create the most colorful view of the universe. NASA’s james webb space telescope and hubble space telescope They teamed up to study a vast galaxy cluster known as MACS0416. The resulting panchromatic images combine visible and infrared light to assemble one of the most comprehensive views of the universe ever captured. MACS0416, located approximately 4.3 billion light-years from Earth, is a pair of colliding galaxy clusters that will eventually merge to form an even larger cluster. Details revealed by the combination of stretching and contraction forces

This image reveals a wealth of detail only possible by combining the power of both space telescopes. This includes an abundance of galaxies outside the cluster and a scattering of light sources that change over time, possibly due to gravitational lensing (distortion and amplification of light from distant background sources). It is.

The galaxy cluster was the first in a series of unprecedented cosmic views into ultra-deep space from an ambitious joint Hubble program called Frontier Fields, launched in 2014. Hubble pioneered the search for some of the faintest and youngest galaxies ever detected. Webb’s infrared vision greatly enhances this deep observation by going even deeper into the early universe with its infrared vision.

This image of galaxy cluster MACS0416 highlights gravitational lensing background galaxies that existed about 3 billion years after the Big Bang. The galaxy contains an ephemeral object that the scientific team has named Mothra, whose brightness changes over time. Mothra is a star that is magnified at least 4,000 times. The researchers believe that Mothra is magnified not only by the gravity of the galaxy cluster MACS 0416, but also by an object known as a millilens, which weighs about the same as the globular cluster.

Roger Windhorst of Arizona State University, principal investigator of the PEARLS program (Extragalactic Field for Reionization and Lensing Science), which carried out the Webb observations, said: “We are looking at objects that are farther away and fainter. “By doing so, we are building on Hubble’s legacy.”Understand image color and scientific goals

To create the images, the shortest wavelengths of light were generally color-coded as blue, the longest wavelengths as red, and the intermediate wavelengths as green. The wide range of wavelengths from 0.4 to 5 microns provides particularly vivid galactic landscapes.

These colors provide clues to the galaxy’s distance. The bluest galaxies, as most commonly detected by Hubble, are relatively nearby and often exhibit intense star formation, while the redder galaxies, as detected by Webb, tend to be more distant. Some galaxies appear very red because they contain large amounts of cosmic dust that tends to absorb bluer-colored starlight.

“Until we combine the Webb data with the Hubble data, we won’t get the full picture,” Windhorst said.Scientific discoveries and the “Christmas Tree Galaxy Cluster”

New Webb observations contribute to this aesthetic view, but they were taken for a specific scientific purpose. The research team combined his three epochs, each conducted a few weeks apart, with his fourth epoch by the CANUCS (Canadian NIRISS Unbiased Cluster Survey) research team. The goal was to search for objects that change in brightness observed over time, known as transients.

They identified 14 such transients across the visual field. Twelve of these transients are located in three galaxies that are highly magnified by gravitational lensing, and may be individual stars or star systems that are temporarily highly magnified. The remaining two transients are in more moderately expanded background galaxies and may be supernovae.

“We call MACS 0416 the Christmas Tree Galaxy Cluster, both because it is so colorful and because of the flashing lights found within it. Transients are seen everywhere. ” said Haojing Yang of the University of Missouri-Columbia, lead author of a paper describing the scientific results.

Among the transients the team identified, one in particular stood out. It is located in a galaxy that existed about 3 billion years after the Big Bang and has been magnified by at least 4,000 times. The research team nicknamed the system “Mothra” for its “monstrous nature” of being extremely bright and highly magnified. It joins another lensed star that researchers previously identified and named “Godzilla.” (Godzilla and Mothra are both giant monsters known as kaiju in Japanese movies.)

Interestingly, Mothra can also be seen in Hubble observations taken nine years ago. This is unusual because zooming in on stars this much requires a very specific alignment between the foreground galaxy cluster and the background stars. The mutual motion of stars and star clusters should eventually dissolve the alignment.

Lunar.dev seeks to assist developers in controlling the expenses associated with using third-party APIs

Posted on November 9, 2023 by Igor Mitreski

Developers are increasingly using third-party APIs to build applications, and the cost of some APIs can quickly increase. It has been difficult for businesses to understand and find ways to manage these costs.

That’s where Lunar.dev comes in. It’s a tool designed from the ground up to help developers monitor, manage, and take control of their API billing. Today, the company is releasing an open source version of the tool and also announcing a $6 million seed investment.

Lunar CEO Eyal Solomon said that businesses are increasingly relying on third-party APIs to quickly add functionality to applications such as payments, instant messaging, and access to large language models. Masu. These APIs make it easy to add this type of advanced functionality, but can have an impact in terms of monthly usage costs. “As enterprises expand their use of APIs, we’re seeing them build their own internal solutions to better manage and enforce control over the use of third-party APIs,” Solomon told TechCrunch. told.

They weren’t aware of a viable product for managing the use of third-party APIs, so they set out to build one. “The way we look at things is that we focus solely on consumption to help businesses reduce costs and maintain flawless performance and efficiency when it comes to using APIs,” he said.

Installation involves starting a Docker container that loads the Lunar proxy and Lunar interceptor. This allows you to see API traffic flowing through your development pipeline to your API provider. Lunar does not need to connect directly to the API to understand usage. After installation, it will automatically start intercepting your API traffic. Through a command line interface, developers can set usage policies, such as the maximum cost allowed, and those policies are implemented as traffic flows through the interceptor. A graphical interface for policy configuration is planned in the roadmap.

“We are in the developer pipeline, between the natural traffic from production to the API provider, where all the policies and policies are implemented and enforced,” Solomon said. says.

The company decided to start with an open source version of the tool to increase developer buy-in. In the future, we plan to build managed services for companies that don’t want to deal with raw open source, and this is ultimately how we make money. Lunar releases open source products in the following ways: MIT licenseAnd Solomon says open source components are important to his company and its development.

“We are open source, and being open source is some of the key building blocks on our platform. It’s something we’re dedicated to. [offering] our community of developers and engineering teams,” Solomon said.

The company is currently a small company with eight employees split between locations in Tel Aviv and San Francisco, but is currently hiring and seeking R&D and marketing personnel.

The $6 million seed was led by Uncork Capital, with participation from Angular Ventures.
