---+ 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.

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.

Avant la fin de la lumière,
Nous te prions, Dieu Créateur,
Pour que, fidèle à ta bonté,
Tu nous protèges, Tu nous gardes.

Que loin de nous s'enfuient les songes,
Et les angoisses de la nuit,
préserve-nous de l'ennemi :
Que Ton amour sans fin nous garde.

Exauce-nous, Dieu, notre Père,
Par Jésus-Christ, notre Seigneur,
Dans l'unité du Saint-Esprit,
Régnant sans fin dans tous les siècles.

---

To Thee before the close of day,
Creator of the world, we pray
That, with Thy wonted favour, Thou
Wouldst be our guard and keeper now.

From all ill dreams defend our sight,
From fears and terrors of the night;
Withhold from us our ghostly foe,
That spot of sin we may not know.

O Father, that we ask be done,
Through Jesus Christ, Thine only Son,
Who, with the Holy Ghost and Thee,
Doth live and reign eternally.

---

Te lucis ante términum,
rerum Creátor, póscimus,
ut pro tua cleméntia
sis præsul et custódia.

Procul recédant sómnia
et nóctium phantásmata;
hostémque nostrum cómprime,
ne polluántur córpora.

Præsta, Pater piíssime,
Patríque compar Unice,
cum Spíritu Paráclito
regnans per omne sǽculum.

Yoshua Saluda a Mamá Felicia #3. Video from Julio Rodríguez
April 27, 2020

هَلمَوا يَا شُعُوبُ ، تبَاركُ الرَبَ
(Haloummou ya shou'oubou noubarekou'rab.)

Sing praises, all you peoples, sing praises to the Lord.
Sjung lovsång, alla länder, och prisa Herrens namn!
Lobsingt, ihr Völker alle, lobsingt und preist den Herrn.
Cantai todos os povos, louvai nosso Senhor.
Que todo el mundo alabe, alabe al Señor.
Giedokit visos tautos, giedokit Viešpačiui.
Sifuni watu wote sifuni Mwenyezi.
Oh, kiitle nüüd kõik rahvad, oh, kiitke Jumalat.
