Simple, inexpensive method for guarding carbon fiber

For the past 50 years, manufacturers have considered carbon fiber a dream material: Though individual fibers are thinner than a strand of human hair, they can be twisted together and fused with a matrix material to form a ...

A new key for species identification in salt marsh harvest mice

It's hard to save what you can't identify. That's been a problem for the endangered salt marsh harvest mouse, which is found only in the salty, brackish waters of the San Francisco Bay area. The mouse competes for space with ...

How air pollution changed during COVID-19 in Park City, Utah

As luck would have it, the air quality sensors that University of Utah researcher Daniel Mendoza and his colleagues installed in Park City, Utah in September 2019, hoping to observe how pollution rose and fell through the ...

Coastal wetlands are nature's flood defences

Coastal wetlands—such as salt marshes—provide even more flood protection than previously thought, reducing the risk to lives and homes in estuaries, a new study has revealed.

Wildlife, air quality at risk as Great Salt Lake nears low

The silvery blue waters of the Great Salt Lake sprawl across the Utah desert, having covered an area nearly the size of Delaware for much of history. For years, though, the largest natural lake west of the Mississippi River ...

Norway salmon farming moves to cleaner waters: indoors

Hundreds of thousands of salmon swim against the current in southeast Norway—in massive indoor tanks away from the nearest river as the controversial industry increasingly embraces greener land-based facilities.

Are coastal marshes drowning faster than expected?

Salt marshes are a fundamental habitat for fishes and birds, can capture and bury large quantities of organic carbon, and play an important role in protecting coastal communities from storm surges. Comprised of a delicate ...

Salt

Salt is a dietary mineral composed primarily of sodium chloride that is essential for animal life, but toxic to most land plants. Salt flavor is one of the basic tastes, an important preservative and a popular food seasoning.

Salt for human consumption is produced in different forms: unrefined salt (such as sea salt), refined salt (table salt), and iodized salt. It is a crystalline solid, white, pale pink or light gray in color, normally obtained from sea water or rock deposits. Edible rock salts may be slightly grayish in color because of this mineral content.

Chloride and sodium ions, the two major components of salt, are necessary for the survival of all known living creatures, including humans. Salt is involved in regulating the water content (fluid balance) of the body. Salt cravings may be caused by trace mineral deficiencies as well as by a deficiency of sodium chloride itself. Conversely, overconsumption of salt increases the risk of health problems, including high blood pressure.
