Space Telescope Uncovers Massive Galaxies Near Cosmic Dawn Galaxy

CAPE CANAVERAL, FLORIDA – Galaxy Astronomers have discovered what appear to be massive galaxies 600 million years after the Big Bang, implying that the early universe may have had a stellar fast-track that produced these “monsters.”

While the new James Webb Space Telescope has discovered even older galaxies, dating back to within 300 million years of the universe’s birth, scientists are taken aback by the size and maturity of these six apparent mega-galaxies. They published their findings on Wednesday.

Ivo Labbe of Australia’s Swinburne University of Technology and his colleagues expected to find small baby galaxies this close to the universe’s beginning, not these whoppers.

“While most galaxies in this era are still small and only gradually growing larger Galaxy over time,” he explained in an email, “there are a few monsters that fast-track to maturity. It is unknown why this is the case or how this would work.”

Each of the six objects appears to be billions of times heavier than our sun. According to scientists, the total weight of all its stars in one of them could be 100 billion times greater than our sun. Their findings were published in the journal Nature.

Labbe states these galaxies are extremely compact, cramming in as many stars as our Milky Way in a relatively small slice of space.

Labbe and his colleagues initially doubted the findings, believing that galaxies as mature as the Milky Way couldn’t exist so early and still needed to be confirmed. The objects appeared so large and bright that some team members thought they had made a mistake.

“We were completely taken aback, almost incredulous,” Labbe said.

Joel Leja of Pennsylvania State University, who participated in the study, refers to them as “universe breakers.”

“The discovery that massive galaxy formation occurred extremely early in the universe’s history challenges what many of us thought was settled science,” Leja said. “It turns out we found something so unexpected it creates problems for science. It calls into question the entire picture of early galaxy formation.”

These observations were among the first from the $10 billion Webb telescope launched just over a year ago. The Hubble Space Telescope is being replaced by NASA and the European Space Agency’s Webb Space Telescope, which is celebrating its 33rd anniversary of launch.

Unlike Hubble, the larger and more powerful Webb can peer through dust clouds with its infrared vision and discover previously unseen galaxies. Scientists hope to see the first stars and galaxies formed after the universe was created 13.8 billion years ago.

The researchers are still waiting for official confirmation through sensitive spectroscopy and are being cautious in calling these candidates massive galaxies for the time being Galaxy. According to Leja, some objects could be obscured by supermassive black holes rather than galaxies.

While some may turn out to be smaller than expected, “odds are good that at least some of them will turn out to be” galactic giants, according to Labbe. “We’ll find out in a year.”

Webb’s first lesson was to “let go of your expectations and be ready to be surprised,” he said.

nvidia

Nvidia’s market value has reached $2 trillion (£1.58 trillion), marking a new milestone in the chipmaker’s meteoric rise to the ranks of the world’s most valuable corporations.

Shares of the Silicon Valley corporation gained more than 4% in opening trading on Friday before falling slightly.

The gains built on the company’s impressive earnings announcement earlier this week.

The company is profiting from improvements in artificial intelligence (AI), which has boosted demand for its processors.

The company’s turnover doubled last year to more than $60 billion, and CEO Jensen Huang told investors this week that demand was “surging” worldwide.

The corporation, which became worth $1 trillion less than a year ago, is now the world’s fourth most valuable publicly traded company, trailing Microsoft, Apple, and Saudi Aramco.

AI Chip Firm Nvidia Valued At $2tn

After shares fell from their early Friday highs, the company’s market capitalization ended the day just under $2 trillion.

Nvidia was founded in 1993 and was originally recognized for producing computer processors that processed images, primarily for computer games.

Long before the AI revolution, it began adding capabilities to its chips that it claims to aid in machine learning, which has helped it acquire market dominance.

It is currently regarded as a vital company to monitor how quickly AI-powered technology spreads throughout the commercial world.

The firm’s stock price has more than tripled the previous year, from less than $240 per share to about $800 in midday trading on Friday.

On Thursday, the day after its earnings release, purchasers snapped up shares, boosting its value by $277 billion, the greatest one-day rise in Wall Street history.

He research has also contributed to a larger market rise, appearing to persuade investors that, as Derren Nathan of Hargreaves Lansdown put it, the AI boom is “living up to the hype”.

The Tesla Cybertruck Is Impressive And Worrying

Published

cybertruck

There was a time when an electric Tesla truck, built to compete with America’s most popular goods, the Ford F-150 and Chevrolet Silverado, appeared to be the perfect way to propel Tesla into the mainstream.

Then, in 2019, Elon Musk revealed the Tesla Cybertruck, a bare metal box with wheels. It is the furthest thing from the mainstream. This truck has ardent fans and much more ardent detractors. However, it has good towing and hauling capabilities despite its edgy design limiting its usability. For some clients, the sacrifice is unquestionably worthwhile.

However, it is possible that Ford and GM are overly concerned.

If it’s a popularity contest, they win. Even after I put a rented Tesla Cybertruck next to a hot-pink McLaren supercar in a shopping centre parking lot in California, the McLaren drivers couldn’t stop chatting about the Cybertruck. The large, bright silver truck drew a crowd everywhere I went, attracting both young people waiting to see one in person and others, usually older, who had no idea what it was.

The Tesla Cybertruck Is Impressive And Worrying

The Tesla Cybertruck resembles nothing else on the road. Its size, which is not quite as long as a Ford F-150 but appears even larger, is also striking. Of course, once the Cybertruck has been on the market for a time, its appeal will fade.

There’s much to enjoy about the Cybertruck, but it also represents a terrible amount of personal arrogance in cold, unforgiving steel. Elon Musk, the CEO of Tesla, has prioritized design and technical goals over customer needs and concerns for other drivers’ safety. As Walter Isaacson’s latest biography of Musk explains, Musk’s obsession with this structure, built from the same steel SpaceX uses for rockets, resulted in the rectilinear mass of naked metal that I was driving through the southern California hills.

It was the most enjoyable electric truck I’d ever driven. I’ve driven practically all of the other electric trucks on the market, including Fords and Rivian, and I don’t anticipate any of them outperforming Cybertruck’s sports-car-like performance. Normally, it is not a priority in a pickup. It has exceptional acceleration and steering that feels quick, sensitive, and agile. Its powerful acceleration, fast steering, and custom-designed Goodyear truck tyres reminded me of driving the Lamborghini Huracán Sterrato, a high-performance sports vehicle outfitted with off-road tyres and higher suspension. However, the Cybertruck is significantly larger and heavier.

Even a light tap on the accelerator swiftly pushed everyone else behind. With its drive-by-wire steering system, a tiny turn of its small, rectangular steering wheel produced tight bends at lower speeds, but it was easy to keep the truck in its lane at greater speeds. With four-wheel steering, it can turn around in a smaller area than one may imagine.

Tesla did not provide CNN with a Cybertruck for testing. Instead, we rented one for more than $1,000 daily from Turo, a-to-peer vehicle rental service. (Turo does not determine the rates; vehicle owners do, and Cybertruck charges have decreased slightly since then.) My Turo host guided me through the Cybertruck’s several unusual controls – by non-Tesla standards.

Instead of a stalk, steering wheel buttons control the turn signals. (Again, this is comparable to a Lamborghini or Ferrari.) I swiped up and down on a truck icon on the centre screen to shift the truck into drive or reverse. (If the screen ever goes blank, there is a row of gear selector buttons on the ceiling, right over the windscreen.) And I had to hunt around on the touchscreen to find the control for the Cybertruck’s single massive windscreen wiper. Everything made sense after driving the vehicle for an hour.

So, what’s with the rearview mirror?
It features a rearview mirror on the windscreen, but it is largely ineffective. With the bed cover closed, nothing is visible from the back window.

Many current SUVs include rearview mirrors that double as video screens, displaying a view from a camera installed in the rear. Tesla could have employed a comparable technology but didn’t. The Cybertruck’s back video view is presented in a small rectangle on the truck’s centre screen. It’s always there while you’re driving.

This seemingly trivial element reveals Tesla’s approach to car controls. The only justification for having the rearview video display within the rearview mirror is that this is where drivers are accustomed to viewing. Similarly, the only purpose for a turn signal stalk is because it is what people expect. For better or worse, Tesla is okay with what you’re used to.

There are indicators that this mentality contributes to greater crash rates, yet if Tesla were designing a vehicle from the start, the unusual choices would be entirely understandable.

Then there’s the Cybertruck’s unusual shape. Other firms have been producing pickup trucks for well over a century, and there are reasons why they are rarely shaped like wedges. In this case, the Cybertruck’s obvious and unnecessary desire to stand out is a hindrance.

Not suitable for freight.
If you load the cargo bed in the Cybertruck and decide you want to reach anything in the front or back window, you’ll need to begin unpacking. It is not accessible by reaching over the side of the bed. The side wall is too high.

Unlike other large trucks, the Cybertruck has nowhere to put your foot to help you reach over the cargo bed’s edge to save the back tyre, which may be sticky with mud and filth. There isn’t even much room to stand on the rear bumper.

The “frunk,” or front trunk, is a rather ineffective afterthought compared to the one on the Ford F-150 Lightning. Ford’s is just larger and has plenty of power outlets, making it a truly useful office. The Cybertruck is useful as a place to sit. However, there is a reasonably sized storage bin.

For now, the Cybertruck is also more expensive than the Lightning. The Foundation Series truck that I drove cost more than $100,000. It will be next year before Tesla says it will begin building trucks for under $60,000.

Most problematic, however, is the manufacturing quality. The cabin is relatively good, although spartan, but that’s the easy part, especially because Tesla eliminates most switches. The difficult element is creating a body from stainless steel, particularly one with relatively straight edges that do not conceal misalignments.

Body panel alignments are primarily cosmetic in most automobiles and trucks. Having large, irregular gaps between different body portions does not look nice. However, most automobiles are not composed of thick, hard-edged stainless steel. Our Cybertruck’s front corners had openings large enough to see daylight through and hard edges protruding from the body.

The Tesla Cybertruck Is Impressive And Worrying

I was concerned that if this vehicle collided with a pedestrian or if someone slid while climbing over the bedside, the unforgiving metal might inflict serious injury. It’s not knife-edged, but it appears to rip through the skin when it hits soft flesh with enough force. I emailed Tesla to see if they had any issues, but I am still awaiting a response. Tesla has been waiting to respond to CNN’s questions for years.

This is not a truck that customers will buy in large numbers, and it’s not simply because Tesla still needs to produce them. It’s entertaining and engaging, but there’s little need to acquire this instead of something more ordinary and useful for those who want to get the job done. It doesn’t do much better – or at least anything significant – than a Ford F-150 Lightning or a Chevrolet Silverado EV, and it will undoubtedly be worse in several critical respects.

If you want to attract a crowd, this is your ride. At least as long as the novelty lasts.

Elon Musk Says Neuralink Implanted Wireless Brain Chip

Published

neuralink

A tech tycoon, Elon Musk, has claimed that his Neuralink company has successfully implanted one of its wireless brain chips in a human.

In a post on X, formerly Twitter, he stated that “promising” brain activity had been observed following the treatment and that the patient was “recovering well”.

The company aims to connect human brains to computers to better treat complex neurological diseases.

A handful of competitor companies have already implanted similar devices.

“For any company producing medical devices, the first test in humans is a significant milestone,” said Professor Anne Vanhoestenberghe of King’s College London.

“For the brain computer interface community, we must place this news in the context that whilst there are many companies working on exciting products, there are only a few other companies who have implanted their devices in humans, so Neuralink has joined a rather small group.”

However, she cautioned that “true success” could only be measured over time.

“We know Elon Musk is very adept at generating publicity for his company,” she said.

Other firms that have made similar achievements in the sector include Switzerland’s École Polytechnique Fédérale in Lausanne (EPFL), which has enabled a paralysed man to walk simply by thinking.

Electrical implants in his brain and spine that wirelessly transfer thoughts to his legs and feet allowed for this.

The breakthrough was reported in the peer-reviewed journal Nature in May 2023.

There has been no independent verification of Mr Musk’s assertions, and Neuralink has not disclosed any details about the technique he claims occurred.

BBC News has contacted Neuralink and the US Food and Drug Administration (FDA) for comment.

Neuralink testing has been condemned, with Reuters reporting in December 2022 that the corporation killed almost 1,500 animals, including sheep, monkeys, and pigs.

In July 2023, the chairman of the US Department of Agriculture, which examines animal welfare allegations, stated that there had been no violations of animal research guidelines at the corporation.

However, the agency is currently conducting a separate probe.

The FDA allowed Mr Musk’s business to test the chip on humans in May 2023.

That cleared the way for the six-year project, in which a robot will surgically implant 64 flexible threads, thinner than a human hair, into a portion of the brain that governs “movement intention,” according to Neuralink.

According to the company, these threads enable their experimental implant, which runs on a wirelessly rechargeable battery, to record and transmit brain impulses to an app that decodes how the person wishes to move.

“[It] has great potential to help people with neurological disorders in the future and is an excellent example of how fundamental neuroscience research is being harnessed for medical advances,” Professor Tara Spires-Jones, president of the British Neuroscience Association, stated.

“However, most of these interfaces require invasive neurosurgery and are still in experimental stages; thus, it will likely be many years before they are commonly available.”

In another post on X, Mr Musk stated that Neuralink’s initial product will be Telepathy.

He claimed Telepathy would allow “control of your phone or computer, and through them almost any device, just by thinking”.

“Initial users will be those who have lost the use of their limbs,” he said.

Referring to the late British scientist who suffered from motor neurone illness, he remarked, “Imagine if Stephen Hawking could communicate faster than a speed typist or auctioneer.” “That is the goal.”

While Mr Musk’s involvement enhances the visibility of Neuralink, several of his competitors have a history extending back two decades. In 2004, Utah-based Blackrock Neurotech implanted the first of many brain-computer connections.

Precision Neuroscience, founded by a Neuralink co-founder, likewise seeks to assist patients with paralysis. Its implant resembles a very thin piece of tape that rests on the surface of the brain and can be inserted through a “cranial micro-slit,” which it claims is a much simpler procedure.

Existing equipment also produced findings. In two independent recent US research investigations, implants were used to record brain activity while a person attempted to talk, which could subsequently be decoded to aid communication.
