Artificial intelligence: YouTube channels spread fake scientific information
YouTube channels have spread false information that Egypt’s pyramids were used to generate energy in ancient times.
A BBC research team specializing in tracking scientific misinformation (scientific misinformation) has found that YouTube channels that use artificial intelligence to create videos may be spreading false scientific information, and that this information may appear to be “educational content” for children.
The research team identified more than 50 channels in more than 20 languages that spread misinformation disguised as science content (mathematics, engineering, science and technology).
These channels include pseudoscience, disinformation, and conspiracy theories, spreading messages such as the pyramids in Egypt powering buildings, denying human-caused climate change, and affirming the existence of aliens.
Our analysis shows that YouTube recommends “bad science” videos to kids with verified educational content.

Kyle Hill is a science teacher who uses YouTube and has a large young audience. A few months ago he started noticing these clips appearing in his viewing suggestions. He says followers of his channel have contacted him about recommended content that appeared legitimate but was full of misinformation. It seems like they are stealing and manipulating the exact content and ideas being promoted on the site.
The videos focused on wild claims with sensational comments, catchy headlines and dramatic imagery to attract viewers.
With more viewers, the channels get more revenue through screen advertising. YouTube accounts for about 45 percent of video ad revenue.
Creators also tag their videos as “educational content,” which means they’re more likely to be recommended for kids.
“Because I’m a science guy, I took this personally,” Hill says. “These channels seem to have hit on the right thing to maximize views with minimal effort.”
Check for fake clips
We found dozens of YouTube channels producing this type of material in languages including Arabic, Russian, Spanish, and Thai. Many of these channels have millions of subscribers. Their videos often reach millions of views.
Channel creators publish content quickly, with many posting multiple videos each day. Because they do this so quickly, the BBC research team suspects they are using AI software to develop them.
There are programs like Chat GPT and MidJourney that, when asked to create new content,for example, a user may request an image of a “black cat wearing a crown” and find that cat instead and get wasted. more time.
To verify this, we captured videos from each channel and used AI detection tools and expert analysis to assess the likelihood of visuals, narration and text being generated using AI.
Our analysis shows that most videos use AI to generate text and images, extract and process material from legitimate scientific videos.
The result is content that appears to be true, but is often untrue.

We all know that maintaining oral hygiene is very important and the most important step to do this is to brush your teeth twice a day with mouthwash and floss.
But according to experts, you could be putting your oral hygiene at risk by storing your toothbrush in the bathroom.
“Storing your toothbrush in the bathroom can expose you to a variety of health problems, but the level of risk varies depending on the bathroom environment and your specific habits,” explains Dr. Payal Bhalla, principal dentist and medical director of Quest Dental.
Dr. Balla says that aerosolized bacteria can pose a problem because “when you flush the toilet, especially when the lid is open, small droplets containing bacteria and other microorganisms can splash out and settle on nearby surfaces, including your toothbrush.”
When your toothbrush is near the toilet, it’s “more likely to come into contact with airborne particles and water splashes” that “lead to contamination.”
Bathrooms can also be a humid environment, which can encourage the growth of bacteria and mold on your toothbrush.
In shared bathrooms, “there is a greater potential for cross-contamination as multiple people use the space and touch different surfaces.”
As for faecal particles, which can be on your toothbrush, Dr. Bhalla explains: “It’s possible to have faecal particles in the bathroom environment, including surfaces like your toothbrush. This can happen when toilets are cleaned. Not closing the lid, and brushing can release small droplets of faecal bacteria and other microbes into the air. .To reduce the risk of faecal particles coming into contact with your toothbrush, you can follow hygiene tips such as rinsing your toothbrush before using it, storing it upright, covering it with the toothbrush, and closing the toilet lid when washing.
She also recommends “rinsing your toothbrush thoroughly under tap water before using it” because it “will help remove any potential contaminants. Also place your toothbrush upright in a toothbrush cup and allow it to air dry. Make sure it doesn’t touch other toothbrushes. ” To prevent cross contamination.
Dr. Bhalla emphasized the importance of changing toothbrushes “every three to four months or so” to keep them healthy and effective.
He added: “To reduce the spread of airborne particles, close the toilet lid before cleaning, use a breathable toothbrush cover to protect your toothbrush from bathroom contaminants, and regularly clean the toothbrush holder or cup to prevent bacteria and mold build-up. “

Scientists believe that September 24, 2182 marks the date that the asteroid “Bennu” will hit the Earth, so the American space agency NASA is preparing to undertake a dangerous mission to prevent a collision and save our planet from destruction.
According to NASA, this space rock passes close to our planet every 6 years, but it will have a very close encounter with Earth after another 159 years, and if it collides with us, its force will be equal to 22 nuclear bombs.
Although the odds of a cataclysmic impact are estimated at 1 in 2,700, NASA sent a spacecraft to Bennu 7 years ago to collect samples from it. They hope the data will help them prepare for an asteroid deflection mission similar to NASA’s DART mission, which successfully changed the orbit of the small asteroid moon Temorphos last year.
The asteroid samples will reach Earth this week, landing in the Utah desert on September 24.
“We’re now in the final stages of this seven-year mission,” Rich Burns, OSIRIS-REx program manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, told the Sunday Telegraph.
Bennu is about 492 meters wide (about half the size of the asteroid that killed the dinosaurs), so it wasn’t big enough to cause global extinction.
NASA estimated that it could have an impact 9 kilometers wide and cause devastation in a radius of about 1,000 kilometers from the crash site.
Between now and 2300 the chance of Bennu colliding with Earth is 1750.
“The raw materials from asteroid Bennu will help shed light on how our solar system formed 4.5 billion years ago and how life began on Earth,” said Nicola Fox, associate administrator of NASA’s Science Operations Directorate in Washington.

Although the bodies of those killed by Hurricane Daniel were decomposing, the organization had no evidence that they had serious infectious diseases, said Dr. Ahmed Suidan, the World Health Organization’s representative in Libya.
“This could happen if the death is associated with an infectious disease like cholera or Ebola,” Zoiden added in an interview with the BBC.
The reports came as fears began to loom on the horizon that the piles of bodies could fuel the spread of disease in Derna, one of the Libyan cities worst hit by the cyclone.
In this regard, he said that any diseases or epidemics are spread only through contaminated water, adding that “there is an urgent need to provide safe drinking water and sanitation to people to avoid spreading any diseases through water or food.”
Zouiten pointed out that one of the World Health Organization’s priorities now is to provide vaccines to pregnant women and children.
He added: “We have seen in different settings that if vaccination programs are disrupted, certain diseases such as measles can re-emerge, and there are some examples where we have seen cases of polio.”
Zouiten also said that the organization’s team will travel on Tuesday to the city of Terna, where some hospitals are no longer in service due to shortages of drugs and medical equipment.
“So, we will now bring this medicine with us to distribute to many centers and have some mobile clinics to go to other areas,” he added.

Al-Sarrouq al-Zaidi, a member of the Supreme Committee for Crisis Management, told the BBC from inside the city of Derna: “We have actually started taking samples of the wells to ensure the safety of the water. . This issue is one of the priorities. Alternative sources are bringing in water treatment units to provide water supply.
Civil society organizations have started providing clean drinking water to cyclone-affected people. Omar al-Tabal, head of the Libyan Youth Hostels Association’s relief and humanitarian work team, told the BBC: “In the first hour we entered Derna, we saw a huge lack of drinking water. , we worked to provide that water. So far we have distributed more than twenty thousand water boxes through the relief aid committee of the association.
Nearly a week after the storm hit, the challenges facing rescuers are mounting. Malek Morsi, the official spokesman for the Libyan Ministry of Health’s Emergencies and Support Center, said there were obstacles to the work of rescue teams, such as logistical support and opening corridors for rescue teams to enter amid the spread of bodies. In addition to the rugged geography of the hills and valleys in Terna City.

The sea is still throwing up bodies, said Major Fathi Muqeib al-Karimi, head of the National Security Commission’s department in the city of Derna.
Major Fathi Muqeib al-Karimi, head of the National Security Commission’s department in Terna, says: “We dug up the bodies and the bodies have been there for a week, and they are very decomposed.” But most of the bodies were in the sea, and the majority of the people tried to escape the flood to the sea, which was not possible, according to Al-Karimi, who was still vomiting corpses.
Al-Quraimi added to the BBC: “We received a lot of help from countries, but the crisis is big and there is almost a city under the sea.”
Regarding procedures for sterilizing corpses, the head of the National Security Commission Department in Terna says, “If we find a corpse under the rubble, we clean it well and put it in bags, of course we have gloves and disinfectants. , but the smell of the corpses became too much… and so we started using two masks instead of one. “
Dr. Al-Jarooq Al-Zaidi, a member of the Supreme Committee for Crisis Management from inside Terna, refutes the spread of the epidemics in the city of Terna on social media: “There are no epidemics so far. and there are no signs of an outbreak of an epidemic,” says a campaign to vaccinate citizens and medical workers. Also people who handle dead bodies directly.

Dr. Al-Sarrouq Al-Zaidi, a member of the Supreme Committee for Crisis Management in Derna city, denied that the pile-up of corpses was causing the epidemic to spread in the city.
‘We don’t expect an epidemic in Terna’
Following the fear of epidemics spreading into the city of Derna, on Tuesday, a team of consultants from the College of Public Health in Benazi arrived in the city to begin conducting a comprehensive study to analyze and assess natural disasters and assess its quality. Drinking water, food security and nutrition.
Dr. Randa Al-Amrouni, dean of the Faculty of Public Health of Benghazi University, the head of the committee, says: “We have experts in the epidemic and reducing its spread. The situation will be assessed and direct solutions will be developed. The same plan will be set, as well as instructions, including complete sterilization.”
Al-Amrouni added to the BBC: “As public health experts, we did not expect an epidemic in the city of Derna. Some rescue groups have provided us with some information that does not suggest any spread of infection, as the bodies are healthy and have not suffered any injuries.
