NASA is attempting something it has never done before: rescuing a space telescope that's slowly falling toward Earth.
The Swift Space Telescope has spent more than 20 years helping scientists study some of the universe's most powerful explosions. It originally orbited about 600 kilometers (over 300 miles) above Earth. At that height, the atmosphere is normally very thin — but increased solar activity has been pushing more of the atmosphere outward, creating extra drag. That drag slowed Swift down and caused its orbit to drop to about 360 kilometers (a little over 225 miles) above Earth.
To save it, NASA launched a rocket carrying a fridge-sized robot called Link. Link will first take pictures of Swift to figure out the safest place to grab hold of it. Then, using three robotic arms and its thrusters, it will slowly push Swift back up into a higher orbit. The whole process could take several months.
The mission is risky, since NASA has never attempted a rescue like this before. But if it works, Swift could keep operating for another decade. A success could also give NASA a blueprint for rescuing other aging spacecraft in the future — including the Hubble Space Telescope.

Okay, ChatGPT can't cure COVID, but using AI to develop vaccines has shown promising results.
Even though COVID vaccines ultimately saved lives, many were lost in the early days of the disease because scientists couldn’t develop the vaccine faster than the virus spread, and they had to update it when the virus mutated. Now, a team at the University of Cambridge has a way to get ahead of things.
They took the genetic blueprint of multiple coronaviruses related to the one that caused COVID-19 (think: the guest list to the worst family reunion ever) and are using artificial intelligence to work on a vaccine that would protect against a range of the viruses. It’s the first time a vaccine’s key component has been designed by AI and tested on people, but the trial’s work could open up a world of possibilities. Success would signify that we can use an AI antigen that’s safe and, importantly, can represent a whole group of viruses. That would mean we could move away from chasing a particular infection when it happens and towards preventing a whole family of viruses.
It’s too soon to know for sure, but scientists are hopeful that this technology can be implemented to replace the flu vaccine, prepare for bird flu, or protect against hemorrhagic fevers like Ebola.
The Democratic Republic of the Congo (DRC) is months into a serious Ebola outbreak caused by the Bundibugyo species of the virus. Its rapid spread has prompted health officials to raise the risk assessment to "very high" nationally, "high" regionally, and "low" globally. The Bundibugyo species has a case fatality rate of about one in three people, and there's currently no approved vaccine for this type of Ebola. Scientists at the University of Oxford are racing to develop one, using a strategy that may sound familiar.
During the COVID-19 pandemic, scientists were able to develop vaccines quickly by using a harmless virus to deliver genetic material from the coronavirus. It may sound like the world’s worst Amazon delivery, but that material acts as instructions to teach the immune system what to recognize, so it can fight the real virus if a person is exposed later. It’s like showing your immune system a "wanted poster" of a criminal, and giving your body time to figure out how to respond if faced with the actual criminal.
Now, scientists are using the same strategy for Ebola: a harmless virus delivers genetic instructions from the Bundibugyo Ebola virus, helping the immune system prepare without causing the disease itself. Health officials hope the outbreak can be contained without a vaccine, but because Ebola can spread quickly and cause severe illness, having a vaccine ready would provide another powerful tool to help stop it — a definite case of "better safe than sorry."
If you’ve ever wanted to ask Brussels sprouts… just… why? Well, you may be able to get pretty close. There’s an exhibition called Talking Plants at Cambridge University Botanic Garden, where visitors can talk to plants! Well, anyone can always talk to plants. But, in this greenhouse, artificial intelligence is being used to get the plants to respond.
The exhibit features a variety of plant life to go with 20 AI personalities a Cambridge professor, Sam, and his team created for the garden. With a QR code and a phone, visitors can come in and engage with the plants, ask them questions, and listen to their responses. Each plant has its own name, personality, and based on where in the world it's from, and some can speak multiple languages. They can even tell jokes!
Ever wanted to hop onto a fluffy cloud? Catch a falling star? Bottle sunshine? Well, you can’t. But what you can do is hold some of the Moon in your hand… if you’re one of the few qualified scientists who are researching new lunar material. Sharing is caring, but these researchers have a great reason for being very precious with moon dust.
Moon dust is some of the rarest material on the planet and, for the first time, China has shared its samples of moon dust internationally. These samples have now racked up some serious frequent flyer miles, traveling across the globe after being taken all the way from the Moon. Talk about jet lag. Until now, scientists have been using samples collected decades ago. It wasn’t until 2020 that China’s spacecraft went to an unexplored spot of the Moon, then returned with 2 kilograms of moon rock. This dust is now being studied, and researchers are working carefully (VERY carefully) to uncover the evidence it has to offer about our universe’s environmental history.
In More Than a Simple Snowflake, Professor Brian Cox explains that while every iceberg has a different shape, they are each made up of tiny hexagonal snowflakes. As snowflakes fall through the sky, electromagnetic forces draw them together. This video is excerpted from BBC’s Forces of Nature, which combines some of the most spectacular sights on Earth with what we know about the Universe to reveal how the Earth’s beauty is created by just a few forces.
In Bees in Decline, visit a collection of bee specimens at the Oxford University Museum of Natural History. There are more than 250 species of bees, and they help pollinate everything from apples to flowers. But bees are in decline, and one reason is the varroa mite, a tiny bug that causes a big problem.
“I’ll ask ChatGPT” is probably something you hear (and say) more and more these days. With AI here to stay, schools are thinking about how to handle the situation.
AI tools like ChatGPT may seem like a quick fix to homework you don’t want to do, but it struggles with the kind of higher-level thinking that students need to be demonstrating. It also has giveaways like repeating questions, offering surface-level answers, and even giving fake or inaccurate references!
But, instead of flat-out banning AI, universities are teaching students how to use it properly. You shouldn’t (and probably can’t) get answers straight from ChatGPT, but there’s a way to use it for initial brainstorming, or as a starting point. After that, students still need to go the extra mile. The goal is to encourage students to learn how to use AI to work with, not instead of, their brains.
Roblox has exploded into one of the most popular gaming platforms in the world, especially for kids ages 8–12. What started as a small company has grown into a massive online universe with more than 40 million user-created games and experiences — from obstacle courses and role-playing worlds to fashion shows and virtual adventures. In fact, Roblox now has more monthly users than Nintendo Switch and Sony PlayStation combined.
But with its huge popularity comes growing controversy. Critics say that because almost anyone can create a game on the platform, some content may not always be appropriate for younger users. That has raised questions from parents and safety experts about how well kids are protected online.
Roblox co-founder and CEO Dave Baszucki says the company takes safety seriously and has “no tolerance” for inappropriate content. The platform has introduced new protections, including limits on messaging for users under 13. Still, reports show that some kids can sometimes find ways around age restrictions, which keeps the debate going.
Baszucki also says millions of users are having positive, creative experiences on Roblox every day — and reminds parents that they ultimately decide whether it’s the right platform for their children.
The article "Exploring the Strangest Locations in the Universe, Where the Rules of Nature Don’t Always Apply" from BBC's Science Focus is about the strange and mysterious places in space and on Earth where the rules of nature seem to be different. These places include planets made of diamonds, stars that spin too fast, and black holes that stretch and squeeze time.
The article "Is Our Universe Stranger Than We Thought?" from BBC's Science Focus is a fascinating look at new research on the Universe that challenges what we thought we knew. Differences in how we measure the Universe's expansion and how galaxies are spread out suggest there may be missing pieces in our understanding of space.
