Yes, NASA Found Evidence of Ancient Life on Mars. Here’s the Real Story

Learn why scientists are cautiously optimistic about the potential biosignatures found in the Sapphire Canyon rock sample.

Just last week, NASA’s Perseverance rover dropped some major news from Mars that has everyone talking. A tiny rock sample, dramatically named «Sapphire Canyon,» is showing tantalizing hints of what scientists call biosignatures. In plain English? Potential signs that ancient, alien life might have once existed on the Red Planet.

Perseverance snagged this promising sample from a rock in Jezero Crater, which happens to be a dried-up ancient riverbed. The fact that this area was once flush with water is a huge deal, since that’s a key ingredient for life as we know it. While this isn’t a smoking gun for little green men, it’s a massive clue.

As one NASA scientist put it, finding proof of past life would seriously «increase the possibility that some form of life has survived» underground on Mars today — a pretty wild thought to chew on.

Life on Mars?

So, does this finally confirm that life once existed on Mars? It’s a very good start, and the most significant lead NASA has found so far. Dr. Rench was clear on this point. «This discovery significantly increases our chances of finding ancient signatures of life at Mars. It suggests the possibility of life on Mars several billion years ago. It does not provide any evidence for life on Mars today.»

The data collected by Perseverance using its onboard instruments (X-ray lithochemistry and NASA’s SHERLOC scanner) was peer-reviewed and appears promising, but it doesn’t absolutely confirm life. More tests and input are needed for that, and the samples could have been generated from a natural chemical process without the presence of life. But scientists are excited about these signs and eager to learn more.

What kind of Mars life are we talking about? It’s not the sort that comes in peace, or goes much of anywhere. The possible biosignatures indicate small, microbial life. Sapphire Canyon showed signs of vivianite and greigite. Vivianite, in particular, is found on Earth’s peat bogs and swamps, while greigite is a byproduct some earth microbes leave behind. Think of this finding like a potential algae or swamp scum.

NASA is working on analyzing the data, running more tests and sharing the results with other scientists around the world to see what more they can learn. There’s a lot to rule out, from accidental sample contamination to the likelihood of nonorganic origins. That’s tough to do from millions of miles away, but NASA is on the case.

Fitbit Launches Luffu, AI-Powered Health Tracking for the Whole Family

Soon, you may be able to access every family member’s health data in one place.

If you’ve ever wanted a way to keep all of your family’s health records in place, Fitbit may have come up with a solution. Fitbit, well-known for its fitness wearables, announced the launch of its own health care system on Wednesday.

Luffu, which translates to the Old English word for «love,» uses AI to create what it calls an «intelligent family care system.» The platform allows family members to share all their health information through an app.

It’s unclear when Luffu will be officially available, but you can sign up for the waitlist to get access to the limited public beta. Pricing or other details have not been announced.

Luffu will allow families to keep track of everyone’s doctor’s appointments, test results, vaccine records, medications, symptoms, diet and more. The platform uses AI to learn your family’s health history and patterns, and to alert you to any changes that should be addressed, such as missed medications or abnormal vitals. The AI function organizes the data submitted into the system. The app will also connect to third-party apps and wearables, such as the Fitbit.

Luffu is meant to lighten the mental load of family care by organizing all this health data in one place, its co-founder said.

«I was caring for my parents from across the country, trying to piece together my mom’s health care across various portals and providers, with a language barrier that made it hard to get a complete, timely context from her about doctor visits,» said Luffu co-founder James Park.

Luffu will include alerts and a space to log health and medication information via voice, text, photos, and other health portals and devices. The key medical information can be shared across the platform with spouses, caregivers and parents.

A representative for Fitbit did not immediately respond to a request for comment.
