Ozempic has become all the rage over the past couple of years as countless individuals, including a number of high-profile celebrities, are using the drug to lose a significant amount of weight – but a new simulation shows exactly how it works in disturbing fashion.

Exercise and diets have been the tried and tested routes for anyone wanting to shed some pounds, and while you can walk great lengths or even go for a run every single day, sometimes you need a little help or want to make the process a bit easier.

That’s where GLP-1 inhibitors – known broadly under names like Ozempic, Wegovy, and Mounjaro – come in as they dramatically effect how your body functions to allow you to lose weight more efficiently.

Elon Musk has previously argued that using GLP-1 inhibitors would ‘save America’s health crisis’, backing it up by using one himself over the holiday period, and a number of other key celebrities like Oprah Winfrey and Rebel Wilson have discussed their use of the drug to lose weight.

However, while its results are hard to deny, it can cause a number of worrying side effects which have been revealed in great detail through a new simulation.

Created by Zack D. Films on YouTube, known for his informative and often hilarious simulations, one of his newest videos shows the scientific process of what happens to your body when you take a GLP-1 inhibitor like Ozempic.

The first thing you’ll encounter after taking Ozempic and allowing it to pass through your blood stream is a reduction in your appetite, as the drug specifically activates the parts of your brain that signal that you’re full.

Additionally, your blood sugar is stabilized by the drug in order to avoid sudden cravings, which often amount to unhealthy treats that will cause you to gain weight at a faster rate.

It also slows down how fast your stomach empties food, which will contribute to a reduced feeling of hunger across a longer period of time, which is essential to making you eat less.

While Ozempic is not a magic bullet by any means which makes you lose weight with zero effort, it should in theory noticeably reduce the amount that you’re eating every day, which over time will quickly allow you to drop some pounds.

Like almost every other weight loss method though, Ozempic isn’t free of side effects. Most commonly it’ll make some people feel sick – which is a feature that it shares with the Keto diet, another popular weight loss method.

Additionally, it can even lead to diarrhea, which Zack has wonderfully recreated in the simulation through a trail of poo as our Ozempic-taker runs to the toilet.

“Tbh, watching Zack’s animations make me lose my appetite more than Ozempic,” writes one user in reaction to the ending, with another adding that “the detailed visuals and auditory EFFECTS are GOLD.”

Regardless of the hilarity of Zack’s animations, it goes to show that it isn’t the magic cure-all drug that you might expect, and it comes with challenges that you’d have to be willing to face – especially as Ozempic specifically isn’t FDA approved at this point in time.

Scientists have created the world’s first ‘black hole bomb’ and it could help experts better understand the space phenomenon.

The theory of the black hole bomb was first proposed by physicist Roger Penrose back in 1971.

The idea was that the angular momentum of a moving black hole and the energy that creates could be transferred to a particle close to the black hole.

Two years on from that, another scientist, Yakov Zeldovich, made the discovery that a similar process could take place in other situations.

This includes things like light moving around a fast-spinning metal cylinder.

Zeldovich also believed that if you surround the rotating cylinder with a cylindrical mirror then the energy could be reflected and built up in a positive feedback loop.

This will occur until the energy is vented out or it explodes, producing a black hole bomb.

This theory of extracting energy has finally been put to the test, although thankfully, this was on a much smaller scale.

Instead of using a real black hole in outer space to try out the idea, instead physicists experimented with a safe toy model, although the principles are identical.

Vitor Cardoso, who is from the University of Lisbon in Portugal, spoke to New Scientist about the revelation, where he said: “You throw a low-frequency electromagnetic wave against a spinning cylinder, who would think that you get back more than what you threw in? It’s totally mind boggling.”

He went on to say: “Having accurate measurements in the laboratory of this process really allows you to confidently say, ‘yes, this must happen in black hole physics as well’.”

Hendrik Ulbricht, who conducted the experiment with a team at the University of Southampton in the UK, explained: “We’re basically generating a signal from noise, and that is the same thing that happens in the black hole bomb proposal.”

This test has the potential to help scientists gain a better understanding of how the phenomenon works and could lead to more insight on things including dark matter.

Cardoso added: “If new fields exist, we should be seeing, for instance, gravitational waves being emitted from this cloud around black holes, or we should see black holes spinning down because they’re giving their energy away to these new particles.

“So superradiance is turning black holes into particle detectors, and much better particle detectors than [the Large Hadron Collider at] CERN can be for this type of dark matter.”

The world’s first non-verbal Neuralink patient has spoken out after receiving Elon Musk’s brain chip.

Bradford G Smith became the third person in the world to receive the life changing chip and the first ever non-verbal person to have it implanted.

This is after Smith’s Amyotrophic Lateral Sclerosis (ALS) condition deteriorated, leaving him unable to speak.

On Sunday (April 27), Bradford took to social media to share the results of the procedure.

On X, formerly Twitter, he wrote: “I am the 3rd person in the world to receive the @Neuralink brain implant.

“1st with ALS. 1st Nonverbal. I am typing this with my brain. It is my primary communication.

“Ask me anything! I will answer at least all verified users!

“Thank you @elonmusk!”

One user replied: “How do you control which thoughts get typed and which thoughts you keep private? The normal border between internal and external dialogue is not there for you.”

This prompted a reply from another person who explained: “He explains in the video that he types. He has little to no controlled movement of his hands, so they configured the Neuralink to be controlled by his tongue for typing and a grimace or clench for a click. Fascinating to watch. He also has AI via Grok 3, which follows conversation and offers prompts that he can pick from that helps to speed up conversation for him. If he doesn’t like the prompts, he can always type instead.”

Smith added: “Exactly!”

In a video posted to Musk’s social media platform, where he said that uses the Neuralink implant to control the cursor on his laptop.

As well as this, he can use Grok AI to create a clone of his own voice to speak.

Noland Arbaugh became Neuralink’s first patient to test the neurotech firm’s chip, having it implanted in January 2024.

This was eight years after he was paralysed in a diving accident.

Recalling his adjustment to his disability, Arbaugh told the BBC that he has ‘no control, no privacy, and it’s hard’, adding: “You have to learn that you have to rely on other people for everything.”

Arbaugh continued: “If everything worked out, then I could help being a participant of Neuralink. If something terrible happened, I knew they would learn from it.”

The 30-year-old hoped that by having the chip implanted, he might be able to regain some independence by being able to control his computer again.

After growing up playing video games, Arbaugh noted that this was something he’d ‘had to let go of’ after becoming disabled, however that’s all changed thanks to the chip.

He said: “Now I’m beating my friends at games, which really shouldn’t be possible but it is.”

Medical science has just taken another major leap forward, as the world’s first baby to be conceived by a robot has just been born. While it’s not quite in the sci-fi realms of Westworld, doctors have seemingly cracked the ability to fertilize an egg with the help of a sperm-injecting AI robot.

In vitro fertilisation (IVF) is designed to help those struggling to have a baby, leading to several ways to fertilize an egg. One popular method is intracytoplasmic sperm injection (ICSI), which deals with cases of male infertility. Here, a single sperm cell is injected into mature eggs, taking away the typical journey of sperm having to swim to reach an egg. If successful, the embryos are then inserted into the uterus. Another popular method of IVF is to mix the eggs with sperm in a lab dish, but as these have been around for a while now, the medical industry is adopting a futuristic new method that shows artificial intelligence can do some good.

ICSI is seen as more accurate, but with it, there still comes human error. As Jacques Cohen at Conceivable Life Sciences told New Scientist, ICSI is typically performed manually by skilled embryologists who have to use microinjection systems. Studies have shown that the skill of ICSI embryologists can vary massively, with Cohen adding: “They become tired and distracted sometimes, just like everybody else in most professions, so errors happen that can reduce [the] odds of fertilisation and births.”

Hoping to lead to a higher success rate with ICSI, Cohen and the team have created a robot that can perform 23 ‘key steps’ of ICSI. Although each one is triggered by a human operator at the press of a button as they watch a stream of the process, it can be performed remotely from anywhere in the world.

Using AI, the machine selects the healthiest sperm with the best chance of fertilization based on its appearance. Another step involves zapping the sperm’s tails with a laser, therefore making them easier to pick up and be injected into the eggs.

Even though a similar method has been tried before and resulted in two live births, not all of the steps were automated.

In the latest experiment, the Conceivable Life team recruited a couple where the man had sperm with low mobility. As the woman struggled to produce eggs, donor ones were also used.

Five of eight donor eggs were randomly fertilized by the new system and produced four embryos. The other three eggs were fertilized with the traditional ICSI methods, and all formed embryos.

A different AI model then selected the two ‘best’ embryos by looking at the appearance of the chromosomes, and it turns out that both were produced with the robot system. Cohen admits that this doesn’t mean the robot produced healthier embryos due to the small sample of eggs involved.

Although one of the embryos failed to develop after being inserted into the woman’s uterus, the other led to a successful birth. Even though Joyce Harper at University College London referred ot it as an exciting proof of concept, larger studies need to be undertaken to prove that automated ICSI procedures are superior to manual ones.

Despite this being a seemingly big step in the realm of IVF, Harper suggests it’s likely to be adopted on a wider scale due to the extra costs involved. Still, Cohen is hopeful for the future and concluded: “As we optimise, standardise and refine the system, we expect the cost to the patient and clinic to decline.”
