The Road To CRISPR

Jun 10, 2017

With stories of unhappy air travelers blanketing social media in recent months, one major airline is trying something new.

Delta Air Lines plans to install special bag-check kiosks at Minneapolis-St. Paul International Airport, giving customers the chance to skip waiting in line for an agent. One of the new kiosks will include facial-recognition technology, using a camera to confirm passengers’ faces against their passport photos.

This year marks 50 years since the first microwave oven entered home kitchens. Called the Radarange, the machine sold for a whopping $495 in 1967, and we’ve been nuking our food ever since — but not without lingering questions about how the appliance even works.

Consider, for a moment, the musk ox.

The ancient animal looks a bit like a shaggy, long-haired bison and can be found roaming the cold, Arctic landscapes of places like Alaska, northern Canada and Greenland

Musk oxen “actually went extinct in Alaska in the 1890s, and the state brought them back,” says wildlife biologist Joel Berger, a professor at Colorado State University and senior scientist for the New York-based Wildlife Conservation Society.

Bringing Sensation To Bionic Limbs

On August 21, the continental United States will experience its first total solar eclipse in nearly four decades. With the eclipse’s path stretching from Oregon all the way to South Carolina, cities like Kansas City, Missouri, and Nashville, Tennessee, will be swathed in daytime darkness for a few minutes — and at least a partial eclipse will be visible around the country.  

Marijuana could give a cognitive boost to older brains

Researchers have found a drug that reverses the effects of brain aging in mice — marijuana.

In the study, published in Nature Medicine, German and Israeli researchers tested the memory and cognition of 2-month-old “young” mice, 12-month-old “mature” mice and 18-month-old “old” mice after exposing them to low doses of THC (the main psychoactive component in marijuana) over a monthlong period. 

Once populous on the country’s mainland, the New Zealand sea lion was hunted to extinction there centuries ago. Recently, however, the mammal has been making a comeback: Fifteen New Zealand sea lion pups were born on the mainland last year.

Video producer Chelsea Fiske chronicled government efforts to protect the baby animals in a new film for Science Friday’s Macroscope series, “How to Save the World’s Rarest Sea Lion Pups.” She also discovered a pup in the process.

Stargazers living in upper latitudes occasionally glimpse shimmering splashes of pink, blue and green in the night sky. The phenomenon, known as the aurora, is “a glitter bomb” of charged particles from the sun, says Liz MacDonald, a space plasma physicist at NASA.

The aurora is also notoriously ephemeral and can be difficult to track — which is where citizen science comes in. Recently, a group of aurora chasers in Canada saw something strange in the night sky: a purplish streak occurring further south than most auroras. “And they said, ‘What is this thing?’” MacDonald recalls.

When avians and airplanes collide, we tend to hear the big stories — like when a flock of birds crippled the engines of US Airways Flight 1549 in 2009, forcing a crash-landing in the Hudson River. (All 155 passengers and crew survived.)

But thousands of birds hit planes in the United States each year, to less fanfare. “There are somewhere around 13,000 bird strikes reported to civil aviation and another 4,000 to 5,000 from the military, so it’s quite a few birds every year,” says forensic ornithologist Carla Dove.

The star-nosed mole may take the prize for the most extreme adaptation. Its eponymous nose, which looks like a fleshy pink starfish sticking out of its face, is the most sensitive organ of any mammal's on Earth.

For privacy wonks and internet companies alike, April was a bellwether month: President Donald Trump signed Senate Joint Resolution 34 into law, rolling back internet privacy rules issued last December by the Federal Communications Commission.

From oral history, a 14,000-year-old archaeological discovery

May 7, 2017

In their oral history, the Heiltsuk people describe how the area around Triquet Island, on the western coast of their territory in British Columbia, remained open land during the ice age.

“People flocked there for survival because everywhere else was being covered by ice, and all the ocean was freezing and all of the food resources were dwindling,” says Heiltsuk Nation member William Housty.

And late last year, archaeologists excavating an ancient Heiltsuk village on Triquet Island uncovered the physical evidence: a few flakes of charcoal from a long-ago hearth.

New research from NASA’s Cassini mission has all eyes on Enceladus, Saturn’s sixth-largest moon. The research, recently published in Science magazine, indicates that plumes of vapor escaping from cracks in the moon’s icy shell are full of molecular hydrogen, the fuel for microbial life.
