While known for being the world’s fastest bird–peregrines have been clocked at diving more than 200 miles per hour–these majestic birds were at risk for going extinct 50 years ago. Widespread use of pesticides such as DDT decimated native populations of peregrine falcons.
By 1970, California’s peregrine population had dwindled to only two known nesting pairs statewide. The federal government banned DDT in 1972. And successful restoration efforts spearheaded by organizations like The Peregrine Fund helped revive their numbers. By 1999, they were removed from the federal Endangered Species List. Recent surveys estimate that there are now 300 to 350 nesting pairs in California and more than 2400 pairs nationwide.

--- What’s the origin of the Peregrine Falcon's name?
Peregrine is Latin for "Peregrinus," which means “traveler” or “pilgrim.”
--- How many eyelids do raptors, or birds or prey, like peregrine falcons have?
They have three! Two eyelids are used for closing their eyes, while the third is used for blinking. It’s also called the nictitating membrane and helps to protect their eyes and keep them moist and clean. It’s semi-transparent, so they can actually still see through it when it’s closed.
--- Did you know they have a special bone to protect their eyes?
It’s called a sclerotic ring and helps support and secure their eyeballs within their skulls.

Something is growing inside that fruit fly in your kitchen. At dusk, the fly points its wings straight up and dies in a gruesome pose so that a fungus can ooze out and fire hundreds of reproductive spores.

Some of the scariest monsters are the ones that grow inside another being and take over its body. Think of the movie Alien, where the reptile-like space creature explodes out of its victim’s chest.
That monster might be fictional, but scientists are studying a fungus that’s horrifyingly real — at least for the flies it invades, turns into a zombie-like state and kills in order to reproduce.
“Oh, it’s a nightmare for the flies,” said entomologist Brad Mullens, who studied the fungus at the University of California, Riverside.
The fungus is known by its scientific name, Entomophthora muscae, which means “fly destroyer.” It lives off houseflies and fruit flies, among others.
“It’s a crazy system,” said Carolyn Elya, a biologist at Harvard. “The fungus only kills at dusk.”
Like a killer puppeteer, the fungus follows a precise clock.
At dusk on the fourth or fifth day after it picks up a fungal spore, an infected fruit fly stops flying. It starts behaving erratically, for example climbing up and down toothpicks that Elya puts into the vials where she keeps the infected insects.
Then the fly climbs to the top of the toothpick, a behavior Elya and other scientists refer to as “summiting.”
In an unusual twist, the fly then extends its mouthpart down, and some liquid drips out and glues the fly to the surface it’s standing on. Over the next 10 minutes, the fly’s wings ascend until they’re pointing upwards and it dies frozen in this lifelike pose.
Soon after, white spongy fungus oozes out of its abdomen. This white goo is made up of hundreds of lollipop-shaped protrusions which each launch a microscopic bell-shaped spore at high speed. Now the spores just need to get into another fly to grow.
--- Could this or a similar fungus “zombify” humans?
“No, it's very unlikely,” Elya said. “We can control our bodily temperature to kill invaders.”
-- Can we use the fungus as biological control?
Researchers have tried, but the spores are too fragile to grow in the lab.

Ask most people about crickets and you’ll probably hear that they’re all pretty much the same: just little insects that jump and chirp.
But there are actually dozens of different species of field crickets in the U.S. And because they look so similar, the most common way scientists tell them apart is by the sounds they make.
“When I hear an evening chorus, all I hear are the different species,” said David Weissman, a research associate in entomology at the California Academy of Sciences in San Francisco.
Weissman has spent the last 45 years working to identify all the species of field crickets west of the Mississippi River. In December, he published his findings in the journal Zootaxa, identifying 35 species of field crickets in the western states, including 17 new species. California alone hosts 12 species. But many closely resemble the others. So even for one of the nation’s top experts, telling them apart isn’t a simple task.
“It turns out song is a good way to differentiate,” Weissman said.
--- How do crickets chirp?
On the underside of male crickets’ wings there’s a vein that sticks up covered in tiny microscopic teeth, all in a row. It’s called the file. There's a hard edge on the lower wing called the scraper.
When he rubs his wings together - the scraper on the bottom wing grates across all those little teeth on the top wing. It’s like running your thumb down the teeth of a comb. This process of making sound is called stridulation.
--- How do crickets hear?
Crickets have tiny ears, called tympana on each of their two front legs. They use them to listen for danger and to hear each other calling.
--- Why do crickets chirp?
Crickets have several different types of songs that serve different purposes. The familiar repetitive chirping song is a mating call that male crickets produce to attract females that search for potential mates.
If a female makes physical contact with a male he will typically switch to a second higher-pitched, quieter courtship song.
If instead a male cricket comes in contact with another adult male he will let out an angry-sounding rivalry call to tell his competitor to back off.

---+ How does sand form?
Sand can be anything that has been worn down until it’s reduced to some tiny, essential fragment of what it once was: a granite pebble from the mountains; coral from the sea; obsidian from a volcano; even skeletons of microscopic sea animals. It's also a technical term. Bigger than sand, that’s gravel, smaller? Silt.
By studying the composition and texture of sand, geologists can reconstruct its incredible life history. “There’s just a ton of information out there, and all of it is in the sand,” said Mary McGann, a geologist at the United States Geological Survey in Menlo Park, CA.
McGann recently took part in a comprehensive research project mapping sand’s journey into and throughout San Francisco Bay.
Patrick Barnard, another USGS geologist who helped oversee the project, said that it will help scientists understand how local beaches are changing over time. In particular, Barnard wants to understand why beaches just south of San Francisco Bay are among the most rapidly eroding beaches in the state.
From 2010-2012, Barnard and his team sampled beaches, outcrops, rivers and creeks to track sand’s journey around the bay. They even collected sand from the ocean floor. The researchers then carefully analyzed the samples to characterize the shapes, sizes, and chemical properties of the sand grains.
Barnard said the information provides a kind of fingerprint, or signature, for each sample that can then be matched to a potential source. For example, certain minerals may only come from the Sierra Mountains or the Marin Headlands.
“If we’ve covered all of the potential sources, and we know the unique signature of the sand from these different sources, and we find it on a beach somewhere, then we basically know where it came from,” explained Barnard.
And those species aren’t the only things finding their way into the sand. Manmade materials can show up there, too. McGann has found metal welding scraps and tiny glass spheres (commonly sprinkled on highways to make road stripes reflective) in sand samples from around the bay.
“All of these things can get washed into our rivers or our creeks, or washed off the road in storm drains,” explained McGann. “Eventually they end up in, for example, San Francisco Bay.”
By piecing together all of these clues – the information found in the minerals, biological material and man made objects that make up sand – the researchers ended up with a pretty clear picture of how sand travels around San Francisco Bay.
Some sands stay close to home. Rocky sand in the Marin Headlands comes from nearby bluffs, never straying far from its source.
Other sands travel hundreds of miles. Granite from the Sierra Nevada mountains careens down rivers and streams on a century-long sojourn to the coast.
In fact, much of the sand in the Bay Area comes from the Sacramento and San Joaquin rivers, with local watersheds also playing an important role in transporting sand to the beach.
Although this project focused on San Francisco Bay, the same techniques could be used to study other coastal systems, he added, revealing the incredible life stories of sand from around the world.

The South American palm weevil is bursting onto the scene in California. Its arrival could put one of the state’s most cherished botanical icons at risk of oblivion.

Summer means vacation time, and nothing says, “Welcome to paradise!” quite like a palm tree. Though it’s home to only one native species, California has nonetheless adopted the palm as a quintessential icon.
But a new snake in California’s palm tree-lined garden may soon put all that to the test. Dozens of palms in San Diego’s Sweetwater Summit Regional Park, about 10 miles from the Mexican border, are looking more like sad, upside-down umbrellas than the usual bursts of botanical joy.
The offender is the South American palm weevil, a recent arrival to the U.S. that’s long been widespread in the tropics. Large, black, shiny, and possessed of an impressive proboscis (nose), the weevil prefers the king of palms, the Canary Island date palm, also known as the “pineapple palm” for the distinctive way it’s typically pruned.
A palm tree is basically a gigantic cake-pop, an enormous ball of veggie goodness on a stick. The adult female palm weevil uses her long snout to drill tunnels into that goodness—known to science as the “apical meristem” and to your grocer as the “heart” of the palm—where she lays her eggs.
When her larvae hatch, their food is all around them. And they start to eat.
If the South American palm weevil consolidates its foothold in California, then the worst might still be to come. While these weevils generally stick to the Canary Island palms, they can harbor a parasitic worm that causes red-ring disease—a fatal infection that can strike almost any palm, including the state’s precious native, the California fan.
--- Where do South American Palm Weevils come from?
Originally, Brazil and Argentina. They’ve become common wherever there are Canary Island Palm trees, however, which includes Europe, the Mediterranean, the Middle East.
--- How do they kill palm trees?
Their larvae eat the apical meristem, which is the sweet part of the plant sometimes harvested and sold commercially as the “heart of palm.”
--- How do you get rid of them?
If the palm weevils infest a tree, it’s very hard to save it, since they live on the inside, where they escape both detection and pesticides. Neighboring palm trees can be sprayed for protection.

Brewing coffee is a never-ending science project, according to barista Sam Penix, owner of Everyman Espresso in New York City. Grind-size, brew method, coffee beans (which are really seeds), water temperature can all affect the flavors that end up in your cup. Harold McGee, author of On Food and Cooking, explains some of the chemistry of coffee.
Water bears, also known as tardigrades, can survive boiling, freezing, the vacuum of space and years of desiccation. Biologist Bob Goldstein, of the University of North Carolina Chapel Hill, describes water bears and explains why he studies them.
For humans to travel to the Moon and Mars, they'll need a companion - a lowly weed. Just as Matt Damon survives on Mars in The Martian because he cultivates plants in the red planet's hostile conditions, astronauts will need to understand how to grow plants in extreme climates. Dr. Anna-Lisa Paul and Dr. Robert J. Ferl at the University of Florida, Gainesville Space Plants Lab, put weeds in unique situations - like sending them to the International Space Station - to study their behavior on a molecular level. Their research could pave the way for growing plants in extreme climates on Earth, the Moon, long-term space travel, and even Mars.
