Snow Angels

Spider-Man, schmeider-man. In Alaska, the all-girl Dragon Slayers race to the rescue.
"After a bad call, we talk, cry and give a big group hug," says Patty Yaska (left, with harpoon, on the Kuskokwim River with other Dragon Slayers and the novice Lizard Killers).
(Axel Koester)
At 10:20 a.m. on what passes for a balmy spring day in Aniak, Alaska -- 20 degrees, blinding snow -- Volunteer Fire Chief Pete Brown radios his emergency medical team to meet him at the home of George Peterson, an octogenarian who is struggling for breath. Minutes later, Brown, 57, and his colleagues arrive at Peterson's bedside. "What's wrong with me?" asks the frail man with congestive heart failure. "It hurts."
"We're going to give you some oxygen," Dione Turner tells him in a soothing voice. "It will make you feel better," promises Patty Yaska, hooking him up to the canister. Soon Peterson feels revived enough to banter with his rescuers and to notice that they are astonishingly young. As Patty and Dione, both 17, depart, he turns to his son Ray, who placed the 911 call, and asks, "Who were those girls?" Replies Ray: "They're the Dragon Slayers."

A team of seven high school girls, the angels of Aniak provide the only round-the-clock emergency medical care available to 3,000 people in 14 villages across an area the size of Maryland. At an age when many of their peers are obsessing over glitter eye shadow, these volunteer EMTs -- each of whom has 200 hours of medical and fire-safety training under her belt -- respond to 450 calls a year. The youngest Dragon Slayer, 14-year-old Erinn Marteney, pulled a toddler from a burning home the day after Christmas. Mariah Brown, 17 (Pete's daughter), was once bitten by a drunken man as she dressed his wounds. Team members have revived fellow teens who tried to kill themselves and grandmothers in cardiac arrest. They have rescued a villager who fell through ice, snowmobilers injured in collisions and survivors of small-plane crashes. "It really changes how you are as a person," says Erica Kameroff, 16.

Getting to the victims -- most of whom, like the Dragon Slayers, are Yupik Eskimos and Athabascan Indians -- is a challenge in itself: No roads connect Aniak, 350 miles west of Anchorage and surrounded by rivers, to the rest of Alaska. Through early May the team uses frozen waterways as thoroughfares, traveling in snowmobiles and four-wheel-drive vehicles. In warmer months, when the ice thaws, they often rely on boats.

US renewable energy farms outstrip 99% of coal plants economically – study

Coal in the US is now being economically outmatched by renewables to such an extent that it’s more expensive for 99% of the country’s coal-fired power plants to keep running than it is to build an entirely new solar or wind energy operation nearby, a new analysis has found.

Consumer Reports calls Ford’s automated driving tech much better than Tesla’s

Tesla’s Autopilot, which at its core combines lane keeping assist with traffic aware cruise control to help guide a car down a highway, was once groundbreaking technology.

But today more than half of new vehicles are available with similar advanced driver assistance systems, or ADAS. And in a recent ranking by Consumer Reports, which tested ADAS from 12 different carmakers, Tesla’s ranked seventh.

There are more ways to arrange a deck of cards than there are atoms on Earth

Consider how many card games must have taken place across the world since the beginning of humankind. No one has, and will likely never, hold the exact same arrangement of those 52 cards you did during that game. Just think about that...Crazy, no?

First vaccine to target deadly fungal infections passes preclinical tests

A new vaccine targeting the three most common human fungal infections is showing promising results in early preclinical studies. The data paves the way for future human trials testing this pan-fungal vaccine in the hopes of preventing infections that have been linked to over one million deaths a year.

Pelican Cargo unveiled as world's largest autonomous electric cargo plane

It features a 50-kWh Li-ion battery pack that offers a per-charge range of up to 200 miles (320 km) – plus a 20-minute reserve. Four 25-kW (33.5-hp) electric motors power the two fixed-pitch props to the front and back of each wing, and the aircraft benefits from a fully redundant propulsion, controls and sensor suite.

Concrete traps CO2 soaked from air in climate-friendly test

SAN JOSE, Calif., Feb 3 (Reuters) - A California startup using rocks to soak up carbon dioxide from the air has teamed up with a Canadian company to mineralize the gas in concrete, a technological tie-up that is a first and they say could provide a model for fighting climate change globally.

South Australia plans world's largest electrolyzer and H2 power plant

The state that built the world's first grid-level "big battery" is striking out on an even more ambitious green energy project: the world's biggest hydrogen power station, fed by an electrolysis facility 10 times larger than anything running today.

Environment Minister Tanya Plibersek blocks Clive Palmer's Central Queensland coal mine

The federal environment minister has officially blocked mining magnate Clive Palmer's bid for a new Central Queensland coal mine.

Tanya Plibersek said she rejected the project because of the risks it posed to the Great Barrier Reef, freshwater creeks and groundwater.

Vestas looks to recycle turbine blades headed for landfill

When a wind turbine reaches the end of its working life, components like towers and nacelles can be recycled but blades often end up in landfill. Vestas is looking to commercialize a new chemical process that can break down all epoxy-based turbine blades for reuse.

US will see more new battery capacity than natural gas generation in 2023

Earlier this week, the US' Energy Information Agency (EIA) gave a preview of the changes the nation's electrical grid is likely to see over the coming year. The data is based on information submitted to the Department of Energy by utilities and power plant owners, who are asked to estimate when generating facilities that are planned or under construction will come online.

Silver mirror triples efficiency of perovskite solar cells

Perovskites are one of the most promising new materials for solar cell technology. Now engineers at the University of Rochester have developed a new way to more than triple the material’s efficiency by adding a layer of reflective silver underneath it.

Autoflight breaks Joby's world record for the longest eVTOL flight

Autoflight has debuted its 4th-generation full-size "Prosperity I" eVTOL air taxi prototype with a bang, celebrating the longest-ever recorded flight of an electric VTOL aircraft. Prosperity flew 250.64 km (155.74 miles) on a single charge, relegating Joby Aviation to second place.

Clean energy breakthrough as electricity is produced out of thin air

While most of us will never bear witness to them, many of the world’s smallest organisms have some incredible means of survival. Some soil bacteria, for example, can gobble up hydrogen from the air and use it for fuel if starved of any other food.

Wing debuts a rideshare-style drone delivery network

Ridesharing is convenient in part because there's often a vehicle near you, and Alphabet's Wing wants to extend that advantage to drone delivery. The company is debuting a Wing Delivery Network platform that relies on decentralized and highly automated pickups. Drones charge and deliver in whatever locations make the most sense for the broader system. If demand surges in a given area, more drones can operate around the nearest pads.

Apple, Atari, and Commodore, oh my! Explore a deluxe home vintage computer den

In a world where millions of people carry a 1990s-grade supercomputer in their pockets, it's fun to revisit tech from a time when a 1 megahertz machine on a desktop represented a significant leap forward. Recently, a collector named Brian Green showed off his vintage computer collection on Twitter, and we thought it would be fun to ask him about why and how he set up his at-home computer lab.
