Moon Missions May Introduce Harmful Earth Microbes to the Lunar Surface

The moon might endure far longer than previously thought, raising the concern of contaminating its surface before future lunar missions take place.

Space missions are required to follow the “Planetary Protection” policy, ensuring that microorganisms from Earth do not contaminate other celestial bodies.

Unlike Earth, where protective measures such as the atmosphere and magnetic fields exist, the moon’s surface faces intense high-energy particles from space, extreme temperatures, and harmful ultraviolet rays from the sun, making it a harsh habitat for surviving organisms.

As a result, many astronomers classify the moon’s surface as inherently barren. The Space Research Committee ranks it in the second lowest category of planetary protection, alongside Venus and comets, indicating that “spacecraft-mediated contamination could compromise investigations.”

Nonetheless, new findings from Stefano Bertone of the NASA Goddard Space Flight Center and colleagues indicate that in certain areas near the moon’s poles, which are set to be visited by NASA’s upcoming Artemis Mission, life might survive for several days, possibly over a week. This heightens the risk of contaminating these zones and generating misleading results in the search for extraterrestrial life.

“We’re returning to the moon, leaving traces behind. We need to study what kinds of traces we’re leaving and how to minimize them,” Bertone remarked at the Europlanet Science Congress (EPSC) in Helsinki, Finland, on September 12th.

Bertone and his team discovered five microbial species that show resilience to harsh environments, including black mold (Aspergillus niger) and bacteria Staphylococcus aureus and Bacillus subtilis. They assessed how much ultraviolet radiation these organisms could withstand in their laboratory. They compiled data concerning UV levels on the moon’s surface, sunlight exposure, and temperature fluctuations, which allowed them to create a map indicating where these five organisms could survive for at least one day.

All living organisms can endure well-lit areas outside the permanently shadowed regions where sunlight and ultraviolet rays are absent, making these bright zones prime candidates for lunar exploration. The black mold exhibited the highest resilience, surviving in extensive areas for up to seven days.

“This is a significant study that clearly shows if there’s a risk of contamination, then certain actions need to be taken. However, we must also recognize that these actions have economic implications,” stated Stas Barabash from the Swedish Institute of Astrophysics. For instance, space agencies might decide that equipment requires more thorough sterilization, which could increase mission costs.

Google Aims to Introduce Gemini AI Chatbots for Kids Under 13

Google is set to introduce the Gemini AI Chatbot next week for children under 13 who have Google accounts, as tech companies vie for the attention of younger users with their AI offerings.

“The Gemini app will soon be available for your kids,” the company informed an 8-year-old’s parent via email this week. “This means your child can use Gemini to ask questions and get assistance in creating stories for homework.”

Chatbots will be available to children using their parents’ Family Links, Google services designed for families to set up Gmail accounts and access services like YouTube for their children. To create a child account, parents need to provide information such as the child’s name and birth date.

Regarding Gemini, Google has established guardrails for young users, ensuring that chatbots do not generate certain unsafe content. Karl Ryan, a Google spokesperson, noted that data from children with Family Link accounts will not be used to train AI.

The rollout of Gemini for children is expected to help educational institutions, businesses, and others in assessing the efficiency of common generative AI technologies, thus broadening the use of chatbots among at-risk populations. These systems, which are trained on vast amounts of data, can produce human-like text and realistic images and videos.

Google and other developers of AI chatbots are fiercely competing to attract younger users. Recently, President Trump encouraged educational institutions to adopt these tools for learning. Millions of teenagers are already utilizing chatbots for learning support, writing guidance, and virtual companionship. However, a group of children has cautioned that chatbots can pose serious safety risks.

UNICEF and various national children’s advocacy groups point out that AI systems can be misleading, distorted, and manipulated, making it challenging for young children to understand that chatbots are not human.

“Generative AI is producing hazardous content,” noted UNICEF’s Global Research Office in a statement about the risks and opportunities posed by AI for children.

In an email to families this week, Google acknowledged some risks, informing parents that “Gemini can make mistakes,” and advised them to “help children think critically” about chatbots.

The email also suggested that parents educate children on how to fact-check the responses from Gemini. The company urged parents to remind kids that “Gemini is not human” and to “avoid sharing sensitive or personal information with Gemini.”

The email emphasized that, despite Google’s attempts to filter inappropriate content, caution is still advised.

This week’s Google Mail to Parents highlighted the risks associated with Gemini for children.

Over the years, Google has rolled out various products, features, and safety measures for children and teens. In 2015, Google launched YouTube Kids, a dedicated app for children that remains popular among families.

Other initiatives aimed at attracting children online have raised concerns from government officials and child advocates. In 2021, Meta abandoned plans for Instagram Kids after a group of state attorneys general sent a letter criticizing the company for historically failing to ensure the safety of children on its platforms.

Several prominent tech companies, including Google, Amazon, and Microsoft, have faced significant fines for violating the Children’s Online Privacy Protection Act. Federal regulations mandate that children under 13 must obtain parental consent before any personal information is collected online.

With the launch of Gemini, children with family-managed Google accounts will soon be able to access the chatbot on their own. However, the company advised parents that they can modify their children’s chatbot settings to “disable access” if needed.

“Your child will soon gain access to the Gemini app,” an email to parents stated. “We will also notify you when your child first uses Gemini.”

Ryan mentioned that Google’s strategy for offering Gemini to younger users adheres to federal regulations concerning children’s online privacy.

How soon can Tesla introduce more affordable car options to the market? | Tesla

Tesla’s efforts to make electric cars more affordable are making progress.

After announcing plans to speed up production and start manufacturing low-cost EVs sooner than expected, Tesla’s stock price surged by 12% on Tuesday.

Investors are eager to see what Tesla has in store and how quickly these new vehicles will be available.

What is Tesla planning?

Tesla is reworking its production timeline to launch new models faster.

The company updated its vehicle lineup to accelerate the introduction of more affordable models before the previously projected start date of late 2025.

Elon Musk, President of Tesla, mentioned that production could begin as early as this year or by early 2025.

While details about the design and specifications of the new car remain scarce, it’s known that Tesla had previously discussed creating a cheaper vehicle, referred to as the Model 2, priced below $25,000.

How can I achieve this?

To ramp up production of affordable cars, Tesla may need to modify its Model 2 program.

The company aimed to implement a new manufacturing process that would reduce production costs by half, but this will require substantial investment.

Recent announcements indicate that Tesla plans to build the new vehicle on its current production line, steering away from innovative manufacturing technologies.

Some experts believe this shift signals the abandonment of the Model 2 plans in favor of continuing to produce existing models.

How much does a more affordable car cost?

The exact price of the upcoming “more affordable” model remains unknown, but Tesla initially aimed for a $25,000 price tag to compete with Chinese electric vehicle manufacturers.

However, revised plans suggest that cost savings may not meet previous expectations.

Google and XPRIZE collaboratively introduce $5 million reward to identify practical uses for quantum computers

Can quantum computers help?

Eric Lucero/Google

Google and XPRIZE are launching a $5 million competition to create a quantum computer that could actually benefit society. It’s already known that quantum computers can perform certain tasks faster than classical computers, ever since Google first claimed the quantum benefits of its Sycamore processor in 2019. However, these demonstration tasks are simple benchmarks and have no real-world applications.

“There are a lot of fairly abstract mathematical problems for which quantum computers can prove to provide very significant speedups,” he says. Ryan Babush Google. “However, much of the research community is less focused on adapting more abstract quantum acceleration to concrete real-world applications, or on trying to figure out how quantum computers can be used. I didn’t.”

To this end, Google and the XPRIZE Foundation are inviting researchers to come up with new quantum algorithms as part of a three-year competition. The winning algorithm could potentially solve an existing problem, such as finding a new battery electrolyte that significantly increases storage capacity, but it doesn’t have to actually solve the problem, Babush said. Instead, researchers only need to demonstrate how the algorithm is applied and detail the exact specifications of the quantum computing required. Alternatively, competitors could demonstrate how existing quantum algorithms can be applied to real-world problems that have not been considered before.

The award examines how big an impact an entrant’s algorithm can have, whether it tackles problems similar to those outlined in the United Nations’ Sustainable Development Goals, and how well it can be done on available machines. They will be judged on a variety of criteria, including feasibility. Now or in the near future.

The $5 million prize pool consists of a $3 million grand prize to be split between up to three winners, $1 million to five runners-up, and $50,000 each to the 20 semi-finalists. .

The award could help shift the focus of quantum computing researchers from technical definitions of quantum benefits, such as those demonstrated by Google and IBM, to real-world applications, it said. Nicholas Quesada At the Polytechnic University of Montreal, Canada. “[The prize is] “We realized clearly that this is a very important issue,” Quesada said. “We need to think about what we’re going to do with quantum computers.”

But finding socially beneficial quantum algorithms requires a deeper understanding of how quantum computers work, including how they deal with noise and errors, he said. bill fefferman at the University of Chicago. The award does not address this fundamental aspect of building quantum computers, he says.

“I’m generally very optimistic that we’ll find an algorithm that’s really useful,” Pfefferman says. “I’m not very optimistic that within the next three years we’ll be able to discover those algorithms and implement them on the current hardware that’s going to exist.”

‘Spanish Tech Startup Aims to Introduce 3D Printed Meat to Our Tables’

Cocuus, a cutting-edge technology start-up headquartered in an industrial park on the outskirts of Pamplona, ​​takes on a group of drunken tourists who willingly surrender to the sound of fate, horns and hooves during a bull run in a Spanish city. They are just as happy to embrace every bit of the clichés of their sector. A festival held every July.

Table soccer? check.lager and IPA on tap? check. Inspirational Message – Preferably an homage to Alice in Wonderland with “Before Breakfast She Believes in Six Impossible Things”? Check. How about sci-fi memorabilia, perhaps Tintin's moon rocket or Alien's xenomorph head? Check. clearly.

A clue as to what's different lies in the platters of oysters, tuna, foie gras, bacon, nuggets, steak and charcuterie displayed at the bar. Nothing is what it seems. Steak and pork do contain meat, but like other dishes, they are the result of years of research into “copycat foods,” culminating in the rapid burst of 3D printing.

Founded six years ago by Patxi Larumbe and Daniel Rico, Cocuus continues its loud and disruptive quest to fuse science, technology, and nutrition. It announced its existence three years ago when the duo decided to attract meat lovers in Pamplona and beyond by 3D printing steaks and posting them on social media.

“I knew that if I was going to print something, it had to be something that would piss people off,” says Larumbe, who quit a €100,000-a-year job in construction materials to focus on the startup.

“We knew that printing a big steak would upset a lot of people in Spain, especially in northern Spain. So we printed the steak and posted it on Facebook, Twitter, and LinkedIn. 700,000 people. We got replies. Most of them were people telling us to shove it up our butts. It was crazy and I was really happy.”

Even better, the product also attracted the attention of American food company Cargill, which is now one of Coccus' major investors. This Spanish company also specializes in formulations and machinery used in food printing, and for the past few years has designed and manufactured multi-nozzle printers that can create food products that mimic the taste and texture of meat and fish. . The hardware can also be painted on molded purees to look like a plate of chicken and chips or hake and peas, creating meals that stimulate the eyes and appetites of people with swallowing difficulties.

As befits a self-confessed bunch of sci-fi geeks, much of the inspiration comes from the transport plane that beams the crew of the USS Enterprise between the ship and the planet's surface. Larrambe said Social Media Steak is the result of experimenting with the idea of ​​converting steak cells into data that can be teleported. After taking X-rays and cross-sectional scans of real steaks, they located the cells that make up the meat, fat, and bones, converted them into data, and entered them into a printer.

“We're a group of physicists, geometry mathematicians, geeks, and Star Trek and Star Wars enthusiasts who are starting to research food,” Larumbe says. “Every food company studies things in very similar ways, using nutritionists and food technologists, and they come to very similar conclusions to existing ones. To come up with new cakes. If you get a bunch of bakers together, they'll come up with something very similar to what already exists and what we know as cake.”

But if you combine a physicist with a nutritionist, a machine maker, a baker and a comedian, he added, “you'll create a new kind of cake.”

Cocuus' bacon and foie gras are made from a rich vegetable paste, while the steaks are made with real beef from 50kg of meat that would otherwise be discarded or made into cat food when cows are slaughtered. The fat in steak marbling is made from a vegetable mixture and is much lower in saturated fat than the real thing.

Mr Larumbe exudes confidence in his products as surely as his printers extrude meat and vegetable pastes, but he also takes a swipe at many of his supposed rivals and says they've made light work of the vegan burger boom in recent years. He dismissed it as a “bubble” and pointed out the huge costs and low costs. Yields of lab-grown meat.

When asked what sets his company apart in an already crowded field, he insists it's scale. Cocuus and its partner Foody's have sold 80,000 pieces of meat-free foie gras and 200,000 pieces of cholesterol-free vegan bacon since the products hit Carrefour store shelves last September. Cocius also has the production capacity to produce 1,000 tons of bacon and his 3,000 tons of foie gras annually at his factory in the city of Tudela.

“We are the first company in the world to successfully do this on an industrial scale rather than on an experimental scale,” says Larumbe.

“Secondly, our imitation is complete and has never existed before. There was a vegetarian version, but the content was bad. Thirdly, there is something fundamentally wrong here. We have scientists coming up with different formulations and technologies. All of this means we are the most advanced company in the world in this field, and one that partners with the largest international food companies. about it.”

What has the local reaction been like in areas where beef is highly revered?

Making bacon without pigs or “seeing a bunch of idiots make steaks with 3D printing” may not be appealing to Navarre's farmers, Larumbe admits. But after learning more about the company and understanding that more money could be made for the cows thanks to new technology that utilizes parts that were traditionally thrown or fed to cats, many He says people are coming.

Once again, after spending an hour or two with him, you get the impression that Larumbe doesn't really care about other people's opinions.

“Humanity progresses because of people who disagree,” he says. “There is no progress if you and I agree. We don't agree on everything.”

Caltech Researchers Introduce Novel Error-Correction Technique for Quantum Computers

Researchers at the California Institute of Technology have developed a quantum erasure device to correct “erasure” errors in quantum computing systems. The technique allows fluorescent error detection and correction by manipulating alkaline earth neutral atoms with laser light “tweezers.” This innovation leads to a 10-fold increase in the entanglement rate of Rydberg neutral atomic systems, and is an important step forward in making quantum computers more reliable and scalable.

For the first time, researchers have successfully demonstrated the identification and removal of “erasure” errors.

Future quantum computers are expected to revolutionize problem-solving in a variety of fields, including creating sustainable materials, developing new drugs, and solving complex problems in fundamental physics. However, these pioneering quantum systems are more error-prone than the classical computers we use today. Wouldn’t it be great if researchers could whip out a special quantum eraser and remove mistakes?

Report in magazine Nature, A group of researchers led by the California Institute of Technology has demonstrated for the first time a type of quantum erasure device. Physicists have shown that mistakes can be pinpointed and corrected. quantum computing A system known as an “erasure” error.

“Typically, it’s very difficult to detect errors in quantum computers, because just the act of looking for errors creates more errors,” said Manuel Endres, co-lead author of the new study and co-author of the study. says Adam Shaw, a graduate student in the room. Professor of Physics at California Institute of Technology. “However, we found that with careful control, certain errors can be precisely identified and erased without significant impact. This is where the name erasure comes from.”

How quantum computing works

Quantum computers are based on the physical laws that govern the subatomic realm, such as entanglement, a phenomenon in which particles mimic each other while remaining connected without direct contact. In the new study, researchers focused on a type of quantum computing platform that uses arrays of neutral atoms, or atoms that carry no electric charge. Specifically, they manipulated individual alkaline earth neutral atoms trapped inside “tweezers” made with laser light. The atoms are excited to a high-energy state, or “Rydberg” state, and neighboring atoms begin to interact.

Errors are typically difficult to spot in quantum devices, but researchers have shown that if carefully controlled, some errors can cause atoms to emit light. The researchers used this ability to perform quantum simulations using atomic arrays and laser beams, as shown in this artist’s concept. Experiments show that quantum simulations can be run more efficiently by discarding erroneous atoms that are glowing.Credit: Caltech/Lance Hayashida

“The atoms in our quantum systems interact with each other and generate entanglements,” said the study’s other co-lead author, a former postdoctoral fellow at the California Institute of Technology and now at a French quantum computing company. Pascal Scholl, who works at PASQAL, explains.

Entanglement is what allows quantum computers to outperform classical computers. “But nature doesn’t like to stay in this entangled state,” Scholl explains. “Eventually an error will occur and the entire quantum state will be destroyed. You can think of these entangled states like a basket full of apples, where the atoms are the apples. Over time , some apples will start to rot. If you don’t remove these apples from the basket and replace them with fresh apples, all the apples will quickly rot. It’s not clear how to completely prevent these errors from occurring. Therefore, the only viable option at this time is to detect and remediate them.”

Innovation in error detection and correction

The new error-trapping system is designed so that atoms with errors fluoresce, or glow, when hit by a laser. “We have images of glowing atoms that show us where the errors are, so we can either exclude them from the final statistics or actively correct them by applying additional laser pulses.” says Scholl.

Implementation theory of erasure detection in neutral atom The system was first developed by Jeff Thompson, a professor of electrical and computer engineering. princeton university, and his colleagues.The team recently reported a demonstration of the technique in the journal Nature.

The Caltech team says that by removing and identifying errors in the Rydberg atomic system, the overall rate of entanglement, and therefore fidelity, can be improved. In the new study, the researchers report that only one out of every 1,000 pairs of atoms failed to entangle. This is a 10-fold improvement over what was previously achieved and the highest entanglement rate ever observed for this type of system.

Ultimately, these results bode well for quantum computing platforms that use Rydberg neutral atomic arrays. “Neutral atoms are the most scalable type of quantum computer, but until now they have not had the high degree of entanglement fidelity,” Shaw says.

Snap says that since the pilot program began, 85% of students said AR helped them improve their memory and memory retention. The company also found that AR lessons increased his engagement by nearly 50%, and that 92% of his students found his AR content easy to understand.

“By incorporating custom-built lenses into an easy-to-use mobile application using a camera kit, Inspirit has designed an innovative curriculum that combines Snap’s AR technology with comprehensive learning guides to help teachers create dynamic learning. “We’ve empowered students to achieve their best, regardless of grade. They can learn in the classroom or at home,” the company said in a blog post. “This curriculum is designed to stimulate participation in class, increase confidence levels, and increase students’ sense of self-efficacy.”

Snap’s push into AR for education comes a month after the company shut down its AR Enterprise Services division less than a year after it launched. The initiative, announced in March, gives brands access to tools that allow him to perform AR try-on features, a 3D viewer to see products from multiple angles, fit and sizing recommendation technology, an enterprise manager, and more. became. their digital assets. The company said that ramping up its efforts would require “significant” investments and that it could not continue to fund the efforts.
