‘Perfectly preserved' Ice Age skull extracted from mine in the Canadian Klondike
Initially, only half an of an animal skull, including the jaw, was visibly sticking out of the ground at the Hester Creek mine, according to a June 27 Facebook post from the Yukon Beringia Interpretive Centre.
The team from Yukon Paleontology returned the next day with tools to safely thaw out the find, still solidly frozen in the earth.
Eager to help, the miners aimed their water hoses at the ground directly above the skull, 'which significantly sped up the excavation process,' experts said.
With the miners' assistance, the team removed a complete and 'perfectly preserved' Ice Age horse skull, according to the post.
'The presence of canines tells us this horse was likely male, and because they were only partially erupted, we know he was likely a teenager when he died,' officials said.
The depth at which the skull was found suggests the horse lived about 30,000 years ago, experts said in a Facebook comment.
'Many of the fossils coming out of this area are from the last Ice Age,' experts said.
Paleontologists have identified more than 50 different species of horses that roamed across North America, Europe and Eurasia during the Ice Age.
In the Yukon, the most common was Equus lambei, or the Yukon horse — a relatively small species that stood just under 4 feet tall at the shoulders, according to experts.
Another unique species found in the region toward the end of the Ice Age was the North American stilt-legged horse — characterized by long, thin leg bones and an overall lighter build, experts said.
Experts have not yet identified the species of the Hester Creek fossil. The mine is in Canada's Yukon territory.

Massive, mysterious ‘hot blob' beneath Eastern US is moving toward New York, puzzling scientists
Is this the start of Goo York City? UK scientists have discovered a massive 'blob' of rock underneath the Appalachian mountains that's slowly oozing its way toward New York City, per a slimy new study published in the journal Geology. 'This thermal upwelling has long been a puzzling feature of North American geology,' the study's lead author, Tom Gernon, Professor of Earth Science at the University of Southampton, said in a statement. Officially dubbed the Northern Appalachian Anomaly (NAA), this subterranean slimeball sits 125 feet deep underground and extends 220 miles across New England. The team reportedly discovered it using seismic tomography, a method akin to taking a giant CAT scan of the Earth. 4 Fortunately, the blob won't reach NYC for at least 10 million years, per the study. Christopher Sadowski While originally thought to have formed 180 million years ago when North America broke away from Africa, the new research suggests that it appeared 80 million years ago when the precursor landmasses to Canada and Greenland were splitting apart, LiveScience reported. 'It lies beneath part of the continent that's been tectonically quiet for 180 million years, so the idea that it was just a leftover from when the landmass broke apart never quite stacked up,' said Gernon. In a study published last year in the Journal Nature, the team described how this molten mantle molasses is created when hot rock sitting just outside the Earth's core rises to fill cracks in the crust caused by land rifts. When this material eventually cools, it sinks or 'drips,' causing a ripple effect along the lower surfaces of the continents that has been called 'mantle waves.' 4 uplift the Appalachians, explaining why the mountain range remains so high despite significant erosion over the past 20 million years. Dana – By using a combination of direct geological observations, computer simulations and model plate tectonics and geodynamics, the team was able to replicate the formation of a hot blob 1,120 miles northeast of the Appalachians. They found that the primordial ooze was moving southwest at a clip of 12 miles every million years. 4 A map showing how the Appalachian Mountains may have split from Greenland around 80 million years ago. University of Southampton Fortunately, we don't need to prepare for an a-blob-alypse anytime soon. At this rate, researchers estimate that blob-zilla will reach NYC in 10 to 15 million years, like a very slow-moving B-movie monster — it takes a while for underground movements to make a splash in the Big Apple. 4 'It (the blob) lies beneath part of the continent that's been tectonically quiet for 180 million years, so the idea that it was just a leftover from when the landmass broke apart never quite stacked up,' said lead author Tom Gernon. 06photo – The simulation also showed that the blob may have helped uplift the Appalachians, explaining why the mountain range remains so high despite significant erosion over the past 20 million years. 'Heat at the base of a continent can weaken and remove part of its dense root, making the continent lighter and more buoyant, like a hot air balloon rising after dropping its ballast,' said Gernon 'This would have caused the ancient mountains to be further uplifted over the past million years.' After the blob departs the region, however, the Earth's crust will settle once again and erosion will 'continue to wear down the mountains, gradually lowering their elevation,' the scientist said. This seismic syrup is perhaps also the reason why rare volcanic eruptions can help bring diamonds to the surface, per the study. While the study was predominantly centered around the NAA, the team also focused on its twin, an anomalous hot zone situated beneath North Central Greenland. This tectonic lava lamp, which was created during the same continental fragmentation but on the other side of the rift like a molasses-y mirror, generates heat currents at the base of the miles-thick ice sheet, influencing how the ice moves and melts today. 'Ancient heat anomalies continue to play a key role in shaping the dynamics of continental ice sheets from below,' Gernon said. 'Even though the surface shows little sign of ongoing tectonics, deep below, the consequences of ancient rifting are still playing out.'

‘Dwarf'-like creature found sleeping near Madagascar hotel. It's a new species
As darkness stretched across Madagascar, a 'dwarf'-like creature settled on a tree branch near a hotel and fell asleep. But the night wouldn't be restful. Something about the animal caught the attention of passing scientists — and for good reason. It turned out to be a new species. A team of researchers visited Anjajavy Lodge in March 2023 to survey its wildlife as part of a larger project to classify some 'cryptic'-looking lizards, according to a study published July 23 in the peer-reviewed journal Zootaxa. During their visit, researchers searched the 'forest covering the lodge perimeter' and found several tiny lizards, the study said. Intrigued, they took a closer look at the animals, tracked down a few similar-looking archive specimens and analyzed their DNA. A pattern emerged: These lizards were subtly but consistently different from any known species, the study said. Researchers realized they'd discovered a new species: Lygodactylus anjajavy, or the Anjajavy dwarf gecko. Anjajavy dwarf geckos can reach about 2.5 inches long, researchers said. Photos show the brown-gray coloring of the new species. Some geckos have dark brown-black bands running along their sides, while others have a more marbled-looking pattern. Anjajavy dwarf geckos were found 'most often on tree trunks or sleeping at night on the tip of thin branches,' the study said. Researchers said they named the new species after Anjajavy Lodge because of where it was first discovered and 'in recognition of the support the hotel provided to our research.' A video shared on Facebook by the hotel shows its treehouse-like cabins, beach and surrounding nature reserve. 'It is a profound privilege to see our name forever linked to such rare and remarkable biodiversity,' the hotel wrote in a July 30 Facebook post. So far, Anjajavy dwarf geckos have been found at three sites near the northwestern coast of Madagascar, the study said. Based on this 'rather scattered' distribution and the 'general' threat of habitat loss, researchers considered the new species to be 'at least Vulnerable, if not Endangered.' The new species was identified by its DNA, scale pattern, texture, body proportions and other subtle physical features, the study said. The research team included Miguel Vences, Cecilia Herrmann, Malte Multzsch, Sven Gippner, Delina Razafimanafo, Ny Ando Rahagalala, Sandratra Rakotomanga, Andolalao Rakotoarison, Frank Glaw and Aurélien Miralles. The team also discovered two more new species of dwarf gecko: Lygodactylus arnei and Lygodactylus andavambato.

Are electric scooters safe? A rash of injuries, deaths raises concerns.
SAN FRANCISCO – A 77-year-old man was killed after being hit by an electric scooter while crossing a street in downtown San Francisco in July, the type of serious scooter-pedestrian collision the city's police department calls 'uncommon.'' Other types of e-scooter accidents that result in a trip to the emergency room, however, are becoming all too frequent across the nation. The growing popularity of electric scooters – easily accessible for commuters to reach their final destination or tourists to enjoy sightseeing – has been accompanied by skyrocketing numbers of injuries, typically to the riders and at times to others in their way. A 2023 report by the Consumer Product Safety Commission revealed that from 2017 – when the devices were first introduced at scale – through 2022, the U.S. recorded 360,800 ER visits related to e-bikes, e-scooters and hoverboards, known collectively as micromobility vehicles. Of those visits, 169,300 were linked to the scooters, or 47%. By comparison, ER trips stemming from e-bike accidents added up to 53,200, or less than 15%. Just as concerning, of the 233 micromobility-related deaths the CPSC registered through that six-year stretch, nearly half (111) were from e-scooter incidents, usually as a result of collisions with cars and/or control issues. Scooters mistakenly seen as 'very low risk' After a dip in the early part of the COVID pandemic, the ER-worthy injuries related to powered scooters – mostly the electric variety – have steadily risen from just under 30,000 in 2020 to 118,485 last year, nearly twice the 2023 total (64,329). 'People view scooters as very, very low risk for some reason, but we do see broken wrists, head injuries, neck injuries, cervical injuries. Those are all very common," said Dr. Eric Cioe-Peña, associate professor of emergency medicine and vice president of Northwell's Center for Global Health in Long Island, New York. Cioe-Peña has noticed the surge in injuries over the last five years, coinciding with the rise in e-scooter ridership. According to data from the National Association of City Transportation Officials, dockless scooter ridership in the U.S. was up to 65 million in 2023, the latest year for which the nonprofit has statistics. As of 2024, there were 130 American cities with e-scooter-sharing programs, the Bureau of Transportation Statistics says. And a recent report projects the North American market for e-bikes and e-scooters to grow from about $500 million last year to more than $3 billion by 2033. Ignoring traffic rules and neglecting protection All those rides will inevitably lead to more injuries, and Cioe-Peña expressed concern about the number or riders who ignore the rules of the road – such as blowing past stop signs – and neglect to wear protective equipment, especially helmets. He said the worst e-scooter injuries he has seen at the ER involved a helmetless rider in Staten Island whose vehicle's front wheel hit an irregular spot on the street – possibly a storm drain slot – and was catapulted over the handlebar. The rider landed on concrete, sustaining a severe concussion and ankle and wrist fractures. 'The pedestrian risk is more sensational," Cioe-Peña said, 'but the real burden of disease is head injuries with unhelmeted riders." Studies of helmet use among e-scooter riders are scarce but generally show low percentages, as little as 2%. Alex Engel, a spokesperson for NACTO, said most of e-scooter injuries are sustained by riders, who are vulnerable to potholes or small objects on the road causing accidents. 'With e-scooters the center of gravity is much higher because you're standing on them, and because the wheels are much smaller and there's in general much less shock (absorption), pavement quality tends to matter a lot more than it does for bikes or e-bikes," Engel said. A need for more safe places to ride Still, he pointed out cars are by far the biggest danger to riders, which makes the significant increase in bike lanes across many cities a welcome development for micromobility fans. 'The most important thing any city can do is providing safe places for people to ride," Engel said. 'That provides space for those who are already riding, and it encourages more ridership. There's safety in numbers.'' Few if any cities have bike lanes on every street, and it's not uncommon to see e-scooters on sidewalks, which is generally against the law. Though civic leaders tend to appreciate the e-scooters' eco-friendly convenience, a few cities and two states – Pennsylvania and Delaware – have effectively banned them from public roads. There's wide variation in state and municipal regulations regarding e-scooters, from minimum age requirements to whether riding on sidewalks is allowed, leading to confusion among practitioners. While more than 30 states have set speed limits of between 15 mph and 20 mph, another six permit riders to go at least as fast as 25 mph, according to a detailed guide on the webpage of scooter maker Unagi. Lax enforcement of regulations The regulations are not commonly known and rarely enforced, said Joseph Schofer, a professor emeritus of civil and environmental engineering at Northwestern University who specializes in transportation issues. 'A teenager riding a scooter, my sense is they have no obligation to get training," Schofer said. 'And if there is, there's no way to enforce it." He remembers a few years ago seeing a man on a rental e-scooter riding around Washington, D.C., with his child, maybe 2 or 3 years old, on his shoulders. It was a reminder of the need for better public education regarding these contraptions, not to mention common sense. Schofer said he sees the value in efficient conveyances like e-scooters, which can make it easier to navigate city streets. He also wonders about the risk involved, especially for young riders and tourists who may not be familiar with a town's layout and traffic patterns. 'You have a really cheap avenue to getting access to motorized transportation, and to young people who aren't licensed drivers, and to people of limited income, it's very appealing," he said. 'So how do you make this work?" 'A place in the transportation ecosystem' Dr. Ben Breyer, a professor at the University of California-San Francisco School of Medicine, said that's where city involvement comes in. Breyer spent 10 years at San Francisco's leading trauma center and conducted several studies on bicycle trauma. More recently, he collaborated in a widely cited UCSF study published last summer that found nationwide e-bike injuries nearly doubled and e-scooter injuries rose by more than 45% every year from 2017-2022. Despite that, Breyer's likes the potential for these vehicles. 'These kind of micromobility options do have a place in the transportation ecosystem," he said. 'They help keep cars off the road, they help decrease congestion, they help people make that final mile in their commute. I think we need more infrastructure to help support riders, and there may need to be some regulations on maximum speeds and these kind of things to help ensure folks ride safely."
