Month: November 2025

I’ve been involved with the Rebelle Rally since its inception in 2016, either as a competitor or live show host, and over the past 10 years, I’ve seen it evolve from a scrappy rally with big dreams to the world-class event that it is today.

In a nutshell, the Rebelle Rally is the longest competitive off-road rally in the United States, covering over 2,000 kilometers, and it just happens to be for women. Over eight days, teams of two must plot coordinates on a map, figure out their route, and find multiple checkpoints—both marked and unmarked—with no GPS, cell phones, or chase crews. It is not a race for speed but rather a rally for navigational accuracy over some of the toughest terrain California and Nevada have to offer. There are two classes: 4×4 with vehicles like the Jeep Wrangler and Ford Bronco and X-Cross for cars like the Honda Passport and BMW X5. Heavy modifications aren’t needed, and many teams compete for the coveted Bone Stock award.

For this 10th anniversary, I got back behind the wheel of a 2025 Subaru Crosstrek Wilderness as a driver, with Kendra Miller as my navigator, to defend my multiple podium finishes and stage wins and get reacquainted with the technology, or lack thereof, that makes this multi-day competition so special.

A young woolly mammoth now known as Yuka was frozen in the Siberian permafrost for about 40,000 years before it was discovered by local tusk hunters in 2010. The hunters soon handed it over to scientists, who were excited to see its exquisite level of preservation, with skin, muscle tissue, and even reddish hair intact. Later research showed that, while full cloning was impossible, Yuka’s DNA was in such good condition that some cell nuclei could even begin limited activity when placed inside mouse eggs.

Now, a team has successfully sequenced Yuka’s RNA—a feat many researchers once thought impossible. Researchers at Stockholm University carefully ground up bits of muscle and other tissue from Yuka and nine other woolly mammoths, then used special chemical treatments to pull out any remaining RNA fragments, which are normally thought to be much too fragile to survive even a few hours after an organism has died. Scientists go to great lengths to extract RNA even from fresh samples, and most previous attempts with very old specimens have either failed or been contaminated.

A different view

The team used RNA-handling methods adapted for ancient, fragmented molecules. Their scientific séance allowed them to explore information that had never been accessible before, including which genes were active when Yuka died. In the creature’s final panicked moments, its muscles were tensing and its cells were signaling distress—perhaps unsurprising since Yuka is thought to have died as a result of a cave lion attack.

Our best friends come in a fantastic array of shapes and sizes; a Borzoi looks nothing like a Boston terrier, except for a certain fundamental, ineffable (except to taxonomists) doggyness about them. And it’s been that way almost from the beginning. A recent study of dog and wolf skulls from the last 50,000 years found that dogs living just after the last Ice Age were already about half as varied in their shape and size as modern dogs.

“Shaped like a friend” means a lot of different things

Biologist and archaeologist Allowen Evin, of CNRS, and her colleagues compared the size and shape of 643 skulls from dogs and wolves: 158 from modern dogs, 86 from modern wolves, and 391 from archaeological sites around the world spanning the last 50,000 years. By comparing the locations and sizes of certain skeletal landmarks, such as bony protrusions where muscles attached, the researchers could quantify how different one skull was from another. That suggested a few things about how dogs, or at least the shapes of their heads, have evolved over time.

The team’s results suggest that dogs that lived during the Mesolithic (before settled farming life came into fashion in the Middle East) and the Neolithic (after farming took off but before the heyday of copper smelting; 10,000 BCE is a general starting point) were a surprisingly diverse bunch, at least in terms of the size and shape of their skulls.

A Chinese plant scientist at the University of Michigan, who drew national attention in June 2025 when she was arrested and accused along with another Chinese scientist of smuggling a crop-damaging fungus into the US, pleaded guilty on November 12, 2025, to charges of smuggling and making false statements to the FBI. Under her plea agreement, Yunqing Jian, 33, was sentenced to time served and expected to be deported.

Her arrest put a spotlight on Fusarium graminearum, a harmful pathogen. But while its risk to grains such as wheat, corn, and rice can be alarming, Fusarium isn’t new to American farmers. The US Department of Agriculture estimates it costs wheat and barley farmers more than $1 billion a year.

Tom Allen, an extension and research professor of plant pathology at Mississippi State University, explains what Fusarium graminearum is and isn’t.
