September 1, 1852, British astronomer Richard Carrington was sketching the pattern of sunspots being projected from his telescope onto a white panel. Suddenly, a rare white-light solar flare outshone the rest of the image. Trouble was on its way!
The revolving molten core of our Earth generates a magnetic field – the magnetosphere – that not only orients our compasses but protects us from the sun’s lethal radiation. Intense charged particles from the sun are magnetically bent around the earth. Some follow magnetic lines into the poles and light up the arctic and antarctic skies as aurorae. Periodically, during times of intense surface disturbance, giant flares of energy can burst out of the sun: CMEs, coronal mass ejections. They’re directional and they seldom hit earth. When they do, the most powerful can punch through our magnetosphere.
On September 2, 1852, Carrington’s flare energy reached the earth and danced along the copper wires of our (then) new telegraph system. Hundreds of miles of wire burst into flames. Telegraph offices burned down, operators at their keys were knocked back by severe shocks, instruments and switches melted. For two days the telegraph system that wasn’t destroyed sent nonsense. Then spectacular aurorae that lit up the skies, they, finally, proved that the sun’s energy was the aurora’s source. Aurorae were seen all over the world, even near the equator. After two days the effects ceased.
Could it happen again? It has. In 1882, a flare melted telegraph equipment in Chicago. In 1902, solar energy disrupted the Atlantic telegraph cable and shut down Swiss electric trollies. In 1940, hundreds of miles of American telegraph and telephone lines were destroyed. A solar flare in 1989 almost forced the Space Shuttle Discovery to return to earth early and knocked out Quebec’s electricity; only quick action in New Jersey, where a major transformer melted, saved the United States’ east coast from a long blackout. In 2003, a powerful flare destroyed or disabled many satellites, damaged instruments on our Mars orbiter, and sent the crew of the International Space Station into its flare-shielded module. In 2005, our GPS navigation satellite constellation was knocked out for 10 minutes.
All the life and energy we have comes from the sun. But that energy, itself, is dangerous. We’re partially protected by our magnetosphere. Hope for the best and reach for the sunscreen.

Think you might like to be a helicopter pilot? If so, here’s what the U.S. Flight Aptitude Selection Test for helicopter pilots says: “Helicopter pilots must pass some of the most demanding physical tests of any job in the military. To be accepted for pilot training, applicants must have excellent vision and be in top physical condition. They must have very good eye-hand-foot coordination and have quick reflexes.”
A sense of balance is also extremely important because sometimes instruments alone are not enough to keep a helicopter oriented properly in the air. Pilots may have to make very subtle corrections. So here’s a test for balance. Be forewarned. Not many people can do this, maybe one in twenty.
1. Stand at attention.
2. Make two fists and extend your arms straight down by your sides. Point your index fingers to the ground.
3. Close your eyes.
4. Bend one leg back at the knee so that your lower leg is parallel to the floor and you are standing on one foot. Don’t let your foot droop. You must maintain your knee at a right angle.
5. Keep your eyes closed and hold this position for ninety seconds.
6. Try not to shake.
I learned about this from a Scotsman who told me about this test to qualify for the British Royal Air Force. He couldn't pass it, nor could I. In fact, no one I knew could rise to the helicopter pilot challenge except a Navy pilot in my family. He held the position perfectly for two minutes. Solid like a rock. No problem.
It’s clear that when it comes to certain skills not everyone is equal. Some people are not even close. So very few people are in the running to become helicopter pilots. You're probably not one of them but this may change with training.

Curiosity Queen: writing science, history, and everything in between
Regular visiting hours are over at the Buffalo Botanical Gardens, but the line to see Morty reaches out the door. It’s an event that comes once in a decade, so I’m happy to wait for my chance to see, and smell, what’s inside.
A year ago the Botanical Gardens acquired corms or bulbs of a tropical plant called the corpse flower. These aren’t little tulip bulbs you hold in your hand. The corpse flower corm weighs 120 pounds and looks like a giant potato. A corm that big needs a lot of energy to grow, so, it spends several months dormant underground. When the first hint of green peeks through the soil, it’s a guessing game as to what it will look like. Most of the time, the corpse flower will send up a slender shoot and one complex leaf that looks like a tree canopy. Through photosynthesis, this leaf will provide energy that will be stored in the corm. When there is enough energy stored up, Morty will flower. And that’s what I’m excited to witness.
Weaving my way through displays of cactus, palms, and banana trees, I wonder if someone forgot to take the trash out. The odor of rotting meat wrinkles my nose, and I realize why Morty is called a corpse flower. As we move closer, the air grows thicker. This plant has been dumpster diving.
The stink Morty sends forth is the plant’s way to attract pollinators in its native jungle of Sumatra. The flower only lasts a day or two, so the scent has to be pungent enough to quickly draw in dung beetles and carrion flies that will collect the pollen and distribute it to other plants before it wilts. It’s curiosity that lures me in.
I round the corner and catch my first glimpse of the stinker. Since it poked out of the ground it has grown five to six inches every day, and now Morty’s seven-foot spire, called a spadix, towers over me. I have to step back to catch the entire plant in my camera lens. Like a wicked witch’s collar, Morty wears a single pleated, blood red flower petal wrapped around the spadix. By midnight the flower will be fully opened and have reached maximum reek.
I click more pictures and take a deep breath. It will be a long time before Morty blooms again, and I want to remember every smelly detail.

Earth’s temperatures are getting warmer. In fact, sixteen of the seventeen hottest years on record have occurred since the year 2000. These warmer temperatures are driving larger, long-term changes in our planet’s weather and climate. Scientists refer to these changes as “climate change.”
In a few places, climate change might be welcome, but around the world, warmer temperatures and other changes are leading to a host of problems from rising sea levels to more extreme weather events and the spread of harmful human diseases.
Professor Scott Mills, from the University of Montana, wanted to see how climate change might be affecting one particular animal called the snowshoe hare.
Snowshoe hares live in regions of North America that receive snow every winter. The hares, in fact, change their coat color from brown to white and back again every year. This helps camouflage them against their background—and hides them from the eyes of lynx, owls, and other hungry predators.
Here’s the thing: snowshoe hares can’t choose when they molt, or change their coat color. Molt timing is controlled by their genes, which are part of the DNA inside their bodies. If a hare’s genes make it molt to white in October, but snow doesn’t fall until December, the hare will stick out like a light bulb against the brown earth. And that’s a problem. Why? Because almost everywhere on earth, the length of time with snow on the ground is growing shorter and shorter.
To find out if shorter winters might harm hare populations, Scott and his team spent three years tagging and following hares. They measured how many were born, how many died, and what they died from. They also recorded whether the hares were matched or mismatched against their backgrounds.
They discovered that predators killed mismatched hares significantly more often than hares whose coats match their backgrounds. Scott and his team also calculated that over the next one hundred years, this greater mortality, or death rate, could lead to the decline or disappearance of many snowshoe hare populations.
The good news? Different hares molt at different times. This may help some hare populations adapt to shorter winters and longer periods without snow.
Hares are not the only animals affected by shorter winters. More than twenty species of animals including lemmings, weasels, hamsters, and Arctic foxes change their coat colors every year. Scott’s research helps us predict what might happen to these animals—and decide what we can do to protect them.
Scott’s discoveries about Montana snowshoe hares, together with experts’ predictions about our future climate, indicate that hares will be mismatched between 5-½ and 10 weeks by the end of this century.
Before tagging and putting a radio collar on a snowshoe hare, Professor Mills and his team must weigh and measure it.
This snowshoe hare has been tagged and fitted with a radio collar—and is now ready to help scientists learn more about snowshoe hare survival.

Besides serving as popular prey for predators, snowshoe hares are irresistibly cute. This is a young hare, also called a leveret.

Stories that Surprise and Inspire
In 1963, at a ceremony in Washington, D.C., President Lyndon Johnson awarded singer Marian Anderson the Presidential Medal of Freedom, the highest honor a president can give to a civilian (someone not in the military). He explained why this African American musician was being honored: “Artist and citizen, she has ennobled her race and her country, while her voice has enthralled the world.”
Twenty-four years earlier, however, some in Washington weren’t interested in honoring her but instead treated her unfairly. By then, she had given wonderful concerts of classical music in Europe and the United States, including at the White House. But in 1939, when a local university tried to have her perform at Constitution Hall, Washington’s concert hall, the managers of Constitution Hall wouldn’t let her, just because of the color of her skin.
Eleanor Roosevelt, President Franklin Roosevelt’s wife, was upset by this example of discrimination against African Americans and arranged for Marian Anderson to perform that spring at the Lincoln Memorial. More than 75,000 people filled the area in front of the memorial to hear Marian Anderson sing. Thousands more around the country listened on radio to a live broadcast of the performance. She started by singing “America,” then sang some classical pieces, and ended with spirituals, including “Nobody Knows the Trouble I’ve Seen.” Newspapers and magazines wrote rave reviews, which let thousands more people learn about the dignified and courageous way she had triumphed over discrimination. Four years later, in 1943, she was at last invited to perform at Constitution Hall.
Did this end unfair treatment for this singer? Not exactly. In 1953, Marian Anderson was again denied permission to perform at a concert hall, this time by the Lyric Theater in Baltimore, Maryland. Luckily, this city’s music- and freedom-loving citizens came to her defense. Some wrote letters to newspapers complaining about “this insult to a great American singer.” Others threatened never to go to that concert hall again. Hundreds complained directly to the Lyric’s managers. Finally, Maryland’s commission on interracial relations persuaded the Lyric’s owners to let Marion Anderson perform there on January 8, 1954. The hall was filled to overflowing with her enthusiastic fans.
Ten years later, racial discrimination in concert halls finally became illegal. The Civil Rights Act of 1964 outlawed discrimination based on race, religion, or national origin at any place that serves the public, including concert halls, theaters, stadiums, restaurants, hotels, and anywhere else.
