The journey to Mars will be the greatest yet taken by mankind. But the trip there is just one obstacle — survival on the foreign landscape of the Red Planet is a challenge that scientists around the world are trying to solve.
Two organizations, Two Planet Steel and Food for Mars, hope to make that task a bit more manageable by running experiments on Martian regolith (dust, soil, and rock), testing how to separate iron and heavy metal oxides in order to grow crops and make steel. They’ve launched a Kickstarter campaign to raise funds for their joint research.
Earlier this year, scientists led by Wieger Wamelink in the Netherlands’ Wageningen University Food for Mars program announced that vegetables could be grown from Mars-like soil without dangerous levels of heavy metals. The team managed to raise 10 crops — from radishes to peas — in a soil developed by NASA to replicate that found on the Red Planet.
Over in San Diego, Two Planet Steel’s Rif Miles Olson realized that that steel-making could be done on Mars using robots and small-scale equipment. This would save on transport costs and provide the Mars colony with a technology that it could develop for its specific purposes, like building tools, machinery, and facilities to produce other materials like aluminum and plastics. “Steel will be the embryo material and finished steel objects will the embryo structures that enable us to grow our Martian capabilities in all sorts of ways,” Olson tells Digital Trends.
But Olson thinks the techniques of steel production required for Mars might have impacts here on Earth as well. The autonomous mining rovers could find work here in Earth’s mines. And the production process — which will likely have to function with little or no fossil fuels — may even be implement on Earth without carbon dioxide emissions.
“Investigating making steel on Mars highlighted the fact that it should be possible to make steel here on Earth without producing any CO2 emissions, and that this was also very good and really even better,” Olson says. “My home planet will always be Earth.”
Olson partnered with Wamelink at Food for Mars and launched the Kickstarter campaign Project Food and Steel to spread the word on clean steal production and further investigate regolith processing for crop growth. With under two weeks and almost $17,500 more needed in funding, the goal seems unlikely but not impossible.
Google has been finding more ways to make Gemini a part of your daily routine, from putting together playlists to ordering groceries through your favorite apps. Now it's expanding those capabilities to more services, with Google Search joining in, too.
The company has announced a new Connected Apps Platform that makes it easier for developers to bring their services to both Gemini and Search. Alongside this, Google is adding new partners to its growing lineup, bringing more of the apps people already use into its AI ecosystem.
In the broad context of AI and its perceived harms, health and medical risks often pop up in the conversation. The warnings even come from frontier AI labs, such as ChatGPT-maker OpenAI and Anthropic, both of which have warned about misusing AI to cook up bioweapons. Security experts have already spotted a few such incidents in the wild, especially with the usage of AI models without any solid guardrails.
Well, it appears that the risks run deeper. As per an analysis appearing in the British Medical Journal (BMJ), AI bots are now being deployed to influence public policies governing health risks to citizens. In this instance, an attempt was made using AI bots to thwart regulations that aim to restrict the sale of disposable vapes, all while disguising the manipulation efforts as a response from real humans.
What if checking your drinking water for dangerous chemicals were as simple as plugging a tiny gadget into your smartphone? Researchers in Japan have developed a compact sensor that could make that possible, potentially bringing sophisticated water contamination testing out of expensive laboratories and into people's hands.
Scientists at the Okinawa Institute of Science and Technology (OIST) have created a portable device capable of detecting extremely low concentrations of PFAS, commonly known as "forever chemicals." The findings were published in the journal Biosensors and Bioelectronics, which demonstrate how an inexpensive sensor and a smartphone could make identifying potentially harmful chemicals in water a lot easier.
