Clearing the path for turbulence-free quantum communication

A University of Ottawa team has developed a new way to protect free-space quantum key distribution (QKD) from atmospheric turbulence, one of the main causes of distortion and errors when sending quantum information through air. Their paper, “All-optical turbulence mitigation for free-space quantum key distribution using stimulated parametric down-conversion,” appears in the journal Optica.

Woolly Mammoth ‘Proxy’ Could One Day Roam the North American Tundra

The woolly mammoth may have gone extinct as recently as 4,000 years ago on Wrangel Island near Alaska. However, scientists have been working diligently for years on bringing them back.

In 2019, Japanese researchers made a breakthrough using 28,000-year-old DNA from Yuka, a perfectly preserved baby mammoth found on the Yukaghir coastline of Siberia in 2010. 

Even though she remained frozen for millennia, scientists could extract flowing blood from Yuka, a first in history.

Yuka possibly died as a young mammoth, possibly around age six to eleven. Her body still featured thick and long strawberry blond shaggy hair. If scientists brought back a baby like Yuka, a calf might look much like a living Snuffleupagus.

See Yuka from the BBC below:

Reawakening a Woolly Mammoth

Scientists in Japan implanted Yuka’s cell nuclei into mouse egg cells. For 90-year old Japanese biologist Akira Iritani, his dream of resurrecting the woolly mammoth seemed near.

In five cases, the scientists observed a biological reaction indicating cell division could take place.

Kei Miyamoto, a member of the team at Kindai University in western Japan, told AFP:

“This suggests that, despite the years that have passed, cell activity can still happen and parts of it can be recreated,” said Miyamoto.

“Until now many studies have focused on analyzing fossil DNA and not whether they still function,” he added.

However, Miyamoto said cellular damage was “profound.” Thus, a “Jurassic Park-style resurrection” remained implausible.

“We need new technology, we want to try various approaches,” Miyamoto said.

Therefore, scientists needed better cloning technology and samples. Perhaps then, they could insert mammoth DNA into eggs from their closest living relatives, the elephants. Until methods improved, they would continue with mouse embryos.

Reviving and Restoring Woolly Mammoths

Today, a leading organization in the “de-extinction movement,” called Revive & Restore, hopes to bring back the woolly mammoth. If not the actual species, they could bring back a “proxy” species with similar traits and ecological functions. 

By editing the woolly mammoth’s genes into the Asian elephant genome, the researchers could create “an elephant cousin” more adapted to live in the far north.

“The ultimate goal of Woolly Mammoth Revival is to bring back this extinct species so that healthy herds may one day re-populate vast tracts of tundra and boreal forest in Eurasia and North America. The intent is not to make perfect copies of extinct Woolly Mammoths but to focus on the mammoth adaptations needed for Asian elephants to thrive in the cold climate of the Arctic. The milestones along the way range from developing elephant tissue cultures to genome editing and most importantly, developing insights that help with Asian elephant conservation,” the website states.

Furthermore, as researchers are learning with today’s elephants, these large grazers are essential for maintaining and balancing their environments.

In northern regions, there used to be a “mammoth steppe.” There in the tundra, grazing herds of antelope, deer, caribou, horses, bison, and woolly mammoths roamed. If these grazers came back, their activities could restore the grasslands, preserve the permafrost, and trap carbon. Consequently, the mammoths could help mitigate human-driven climate change.

The project also hopes to revive extinct species like the passenger pigeon and revitalize the Amerian Chestnut tree.

We Are As Gods

A new documentary called We Are As Gods focuses on Stewart Brand, 82, the Stanford-educated author and co-founder of Revive & Restore.

When asked why he wants to bring species back from extinction, Brand says it’s a way to undo humans’ environmental damage.

“As it happens, all three of those projects make a lot of ecological sense. There is a gap in the ecosystems those creatures were in that has not been filled by anything else. If you bring them back, you not only increase biodiversity; you increase resilience.”

To Brand, science can partially empower people to reverse the harm they have done to the natural world.

“But maybe the deeper thing is that we get caught up in our kind of tragic sense of human damage, not only to each other but to the natural world. Most of the damage was done unintentionally. The idea of undoing that damage is potentially very freeing,” Brand says.

The Story of a Woolly Mammoth Named Lyuba

In May 2007, a Nenets reindeer herder named Yuri Khudi discovered Lyuba, a woolly mammoth calf on a sandbar on the Yuribey River in Siberia. A year later, a calf named Khroma was discovered 3,000 miles away.

Nenets believe that mammoths are dangerous omens, creatures that wander the underworld. Worse, some Nenets even believe people who find a mammoth are marked for early death, according to National Geographic.

Nevertheless, Khudi and a friend contacted a local museum, and officials managed to save Khudi’s body from near disaster. Unbeknownst to Khudi, his cousin sold the calf to a local shop where people began taking photos. Meanwhile, stray dogs gnawed part of her tail and right ear. Thankfully, the officials intervened and shipped the mammoth by helicopter to the Shemanovsky Museum in Salekhard, the regional capital.

Later, they named the mammoth Lyuba after Khudi’s wife.

Amazingly, she remained perfectly intact, aside from missing hair and toenails. After thousands of years, she retained her internal organs, stomach still containing milk, bones, milk tusks, and other teeth. Even her eyelashes remained and she looked like she was sleeping.

Mysteriously Well-Preserved

Using carbon-14 dating, scientists in the Netherlands found that Lyuba died 40,000 years ago as a one-month-old.

Notably, traces of sediment in her trunk suggested she died after sinking into the mud and suffocating. Then, scientists suspect her body was pickled and preserved by microbes, which may have discouraged scavengers.

However, it’s mysterious how her body remained preserved and pristine after thawing, possibly for nearly a full year. If pickling had discouraged scavengers, why did the stray dogs attack the body?

Researchers used CT scanners to create 3-D models of Lyuba and  Khroma. 

Since the bodies were too large to scan at a hospital, they required something larger. Thus, they used scanners designed to find flaws in vehicle transmissions at Ford Motor Co.’s Nondestructive Evaluation Laboratory in Livonia, Michigan.

Image: Curiosity rover surveys boxwork region of Mars

NASA’s Curiosity Mars rover captured this panorama of boxwork formations—the low ridges seen here with hollows in between them—using its Mastcam on Sept. 26, 2025, the 4,671st Martian day (sol) of the mission. These boxwork formations were created billions of years ago when water leaked through rock cracks. Minerals carried into the cracks later hardened; after eons of windblown sand eroding away the softer rock, the hardened ridges were left exposed.

NASA’s Bill Nelson Pushes for Scientific UFO Research 1 Month into Office

NASA chief Bill Nelson

Bill Nelson, 78, the former Florida senator and spaceflight veteran, became the NASA Administrator on May 3, 2021. 

One month later, Bill Nelson has directed NASA to study UFOS (or UAPs). Notably, the push comes as a much-anticipated UAP report is due to Congress.

In 1986, Nelson flew on the 24th flight of the Space Shuttle Columbia, conducting 12 medical experiments.

During a CNN interview with Rachel Crane, Nelson claimed that NASA doesn’t know what the authentic UFOs observed by Navy pilots and equipment could be.

Now, he’s quickly leading scientific efforts into the phenomena. 

“Well, I have talked to those Navy pilots, and they are sure that they saw something real,” said Nelson. “And of course, we’ve seen the video from their jets. What is it? We don’t know. So, now that I’m here at NASA, I’ve turned to our scientists, and I’ve said, “Would you, looking at it from a scientific standpoint, see if you can determine so that we can have a better idea?”

Leading UFO Research with Science

Leading with science and evidence is also how former Nevada senator Harry Reid proposes approaching UFO research. In a recent op-ed in the Times, Reid, the man who created the clandestine Advanced Aerospace Threat Identification Program (AATIP), wrote:

“I believe it’s crucial to lead with the science when studying UFOs. Focusing on little green men or conspiracy theories won’t get us far,” he wrote.

Now, NASA could have more funds for scientific inquiry. In the budget for 2022, President Biden has requested a 6.6% increase for NASA science.

No Formal NASA UFO Task Force?

Although Bill Nelson is pushing for scientific research, NASA press secretary Jackie McGuinness says Nelson “did not establish a formal task force,” per CNN. 

Interestingly, McGuinness cited American’s interest in the subject as a reason why NASA scientists are taking a new approach.

“There’s not really a lot of data and…scientists should be free to follow these leads, and it shouldn’t be stigmatized,” McGuinness said, acknowledging that UFO research can be negatively associated with unfounded conspiracy theories. “This is a really interesting phenomenon and Americans are clearly interested in it [so if] the scientists want to investigate, they should.”

In response to the news about NASA, former Deputy Assistant Secretary of Defense for Intelligence Christopher Mellon called the news “wonderful and unexpected news of scientific open-mindedness.” Then, he notes “potential” for NASA’s collaboration with the Intelligence Community.

Bill Nelson isn’t Ruling out Extraterrestrials

When Rachel Crane asked Bill Nelson, “Do you think we have been contacted by extraterrestrials?” he deflected to talking about the Navy pilot’s experience.

Although Nelson denies knowledge of extraterrestrials, he doesn’t rule it out, saying he doesn’t know if it’s ETs, an enemy, or an optical phenomenon.

“…And so the bottom line is, we want to know.”

Then, Crane pushed again, asking Nelson directly, “What do you think it is? What’s your personal take on it?” 

A smiling Nelson replied:

“I don’t have an idea. That’s why I turned to our scientists.”

“What have they said to you?” asked Crane.

“Well, they’re looking into it. Would you like me to call you when I get an answer?” Nelson joked.

Then, Nelson claims that NASA won’t be working directly with the Pentagon on the upcoming UAP report but said, “I can guarantee you if we find something, the Pentagon will want to know.”

The UAP Report

According to recent reports, current and former government officials say military and spy agencies are “blocking or simply ignoring the effort,” to create a UAP report that may come this month.

Meanwhile, the Navy-led Pentagon task force, now called The Unidentified Aerial Phenomena Task Force, or UAPTF, reportedly has few personnel or resources to gather any evidence.

Now, it looks like NASA is not directly contributing to the public report, a notable omission, although they are seeing a budget increase.

Hopefully, there is potential for a collaboration sometime in the future, as Mellon suggests? Right now, it doesn’t seem to be happening – at least not publicly.

For those who have long accused NASA of covering up the truth about extraterrestrials, it comes across as curious. However, tomorrow is a new day, and who knows what may happen next?

Young ‘sun’ caught blowing bubbles by Chandra

For the first time, a much younger version of the sun has been caught red-handed blowing bubbles in the galaxy by astronomers using NASA’s Chandra X-ray Observatory. The bubble—called an “astrosphere”—completely surrounds the juvenile star. Winds from the star’s surface are blowing up the bubble and filling it with hot gas as it expands into much cooler galactic gas and dust surrounding the star. The sun has a similar bubble around it, which scientists call the heliosphere, created by the solar wind. It extends far beyond the planets in our solar system and protects Earth from damaging particles from interstellar space.

Curiosity rover captures Martian spiderwebs up close

For about six months, NASA’s Curiosity Mars rover has been exploring a region full of geologic formations called boxwork, low ridges standing roughly 3 to 6 feet (1 to 2 meters) tall with sandy hollows in between. Crisscrossing the surface for miles, the formations suggest ancient groundwater flowed on this part of the red planet later than scientists expected. This possibility raises new questions about how long microbial life could have survived on Mars billions of years ago, before rivers and lakes dried up and left a freezing desert world behind.
