Zinc can treat deadly jelllfish stings

But in mouse and human blood, the venom’s effects appeared to be blocked by zinc, the scientists report. So Dr. Yanagihara says she is advising a company that is seeking to develop antidotes using the compound zinc gluconate.

A human sized body needs a large dose of venom to be fatal, but the more tentacle that comes into contact with skin, the more deadly venom is injected. Heart failure in the victim rapidly follows a severe sting. Immediate action can save lives.

Palau: A Diver’s Addiction

Palau—prior to a few years ago—was just a name that meant a distant dive destination on my list of places to go. I had seen the periodical article written with its crystal blue water emerald green rock islands and sea life and coral combinations like no other place diving. A dive site called Blue Corner, sounded like fantasy land, almost as if it were thought up by Walt Disney himself, if he were a diver.

The Hooded Nudibranch, Melibe leonina, is also called the Lion Nudibranch. This mollusk is almost transparent with a slight yellowish-green cast.

Nudibranchs have sleep cycles too

Though scientists know that humans have an internal clock that, using the light as a cue, sets and resets itself to control things like falling asleep, the raising and lowering of our body temperatures from day to night, and the slowing of our heartbeats, they don't quite know how that internal clock works on a cellular level.

To try to figure that out, Newcomb has begun researching the lion-hooded nudibranch, a sea slug found in the kelp beds and eel grass that grows in the water along the Pacific coast.

425 million-year-old fossil reveals never-before-seen shrimp species

According to reports posted on BBC Nature, Professor David Siviter discovered the acient fossils that show the shrimps' shells, eyes and limbs.

"The find is important because it is only one of a handful preserving the fossilized soft tissues of ostracods," Siviter said.

Seed shrimp
Ostracods are a type of the crustacean sometimes known as "seed shrimp" typically around 1 millimeter in size. Their bodies are flattened from side to side and protected by a bivalve-like shell.

A WW2-era fighter recovered from Lake Michigan

The Grumman F4F Wildcat was an American carrier-based fighter aircraft that began service with both the United States Navy and the British Royal Navy in 1940. First used in combat by the British in Europe, the Wildcat was the only effective fighter available to the United States Navy and Marine Corps in the Pacific Theater during the early part of Second World War.

More than 17,000 pilots completed the training in Lake Michigan. The aircraft carriers used for the training docked at Chicago's Navy Pier. The pilots flew from Glenview Naval Air Station in Glenview.

Galápagos’ Isabela Island: The Last Mirage

Images by Pierre Constant

Seen from space, Isabela Island—the largest island of the Galápagos archipelago— reminds me of a giant seahorse facing the great blue yonder of the Pacific Ocean. As one approaches land, the cap of thin white clouds dissipates. Isabela’s majestic landscape is a perfect alignment of shield volcanoes, rising above 1,000 metres, which stretches from the southeast to the northwest. Among them, Wolf Volcano reaches 1,700 metres.
