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.

Amazon Prime’s $2.5 FTC Settlement: Learn Who’s Eligible and How Much Payouts Will Be

The online retail giant will soon begin paying misled customers who subscribed to Amazon Prime.

If you thought your Amazon Prime signup process was a little confusing, it’s not just you. The Federal Trade Commission filed a lawsuit against Amazon in 2023, alleging that the retail giant misled customers in marketing Prime subscriptions to its customers. In September, Amazon agreed to pay a $2.5 billion settlement, one of the largest in US history.

The FTC said $1.5 billion will go into a fund to repay eligible subscribers, with the remaining $1 billion collected as a civil penalty. And while Amazon did not admit to wrongdoing, it’s still making changes to how it presents the service. The settlement requires Amazon to add a «clear and conspicuous» option to decline Prime during checkout and to simplify the cancellation process.

«Amazon and our executives have always followed the law, and this settlement allows us to move forward and focus on innovating for customers,» Mark Blafkin, Amazon senior manager, said in a statement. «We work incredibly hard to make it clear and simple for customers to both sign up or cancel their Prime membership, and to offer substantial value for our many millions of loyal Prime members around the world.»

Why did the FTC file a lawsuit against Amazon?

The FTC filed suit against Amazon accused the company of using «dark patterns» to nudge people into Prime subscriptions and then making it too hard to cancel. The FTC maintained Amazon was in violation of Section 5 of the FTC Act and the Restore Online Shoppers’ Confidence Act

«Specifically, Amazon used manipulative, coercive or deceptive user-interface designs known as ‘dark patterns’ to trick consumers into enrolling in automatically renewing Prime subscriptions,» the FTC complaint states.

Who’s eligible for Amazon’s payout?

Amazon’s legal settlement is limited to customers who enrolled in Amazon Prime between June 23, 2019, and June 23, 2025. It’s also restricted to customers who subscribed to Prime using a «challenged enrollment flow» or who enrolled in Prime through any method but were unsuccessful in canceling their memberships.

The FTC called out specific enrollment pages, including Prime Video enrollment, the Universal Prime Decision page, the Shipping Option Select page and the Single Page Checkout. To qualify for a payout, claimants must also not have used more than 10 Amazon Prime benefits in any 12-month period.

Customers who signed up via those challenged processes and did not use more than three Prime benefits within one year will be paid automatically by Amazon within 90 days. Other eligible Amazon customers will need to file a claim, and Amazon is required to send notices to those people within 30 days of making its automatic payments.

Customers who did not use a challenged sign-up process but instead were unable to cancel their memberships will also need to file claims for payment.

How big will the Amazon payments be?

Payouts to eligible Amazon claimants will be limited to a maximum of $51. That amount could be reduced depending on the number of Amazon Prime benefits you used while subscribed to the service. Those benefits include free two-day shipping, watching shows or movies on Prime Video or Whole Foods grocery discounts. 

Customers who qualify for the payments should receive them by Dec. 24.Customers outside the US aren’t eligible for the payout.

How President Jimmy Carter Slayed a Dragon and Is Helping to Eradicate an Ancient Disease

President Jimmy Carter, the Carter Center and LifeStraw have waged a war against Guinea Worm disease since 1986. We’re now closer than ever to completely eradicating an ancient disease from the planet.

Maybe you’ve used a LifeStraw to safely drink water from a stream while camping, or maybe you have one in your home to filter your drinking water. But did you know that the company behind this popular water filtration technology is close to completely eradicating an ancient disease from the planet? 

For thousands of years, Guinea Worm or Dracunculiasis has plagued the continents of Africa and Asia, debilitating its victims and causing incredible pain and suffering. The disease stems from bad drinking water that contains Guinea Worm larvae, which for generations has been unwittingly ingested by humans. Once the Guinea Worm reaches maturity inside its host, the tapeworm bores its way out of the body, usually through the lower extremities. It’s a process that causes incredible pain and discomfort. 

The battle against Guinea Worm is the focus of a new documentary by The Carter Center and Buffalo 8. The President and the Dragon — now playing on Amazon Prime Video, Hoopla and Verizon Fios — illustrates the struggles faced by President Jimmy Carter and the Carter Center in their fight to eradicate Guinea Worm. Carter ran a campaign in motion that used education, technology, surveillance, and a coalition of scientists and volunteers. The goal was to decrease the number of cases of Guinea Worm from 3.5 million victims a year in the 1990s to just 15 cases in 2024. 

If the Guinea Worm Eradication program is successful, Guinea Worm will be the second disease ever eradicated from planet Earth. Smallpox, the first, was declared eradicated by the World Health Organization in 1980. What’s even more remarkable about this accomplishment is that the disease would be eradicated without the use of a vaccine or medicine. 

I traveled to The Carter Center in Atlanta for a screening of Carter’s new documentary. I also interviewed Allison Hill, LifeStraw CEO, and Adam Weiss, the director of the Guinea Worm Eradication Program, about their work to eradicate the disease. You can watch the video to learn more about the documentary and the fight against Guinea Worm. Watch the trailer for The President and the Dragon below.
