A 2-minute video showing an aggressive white shark attacking a seal close to shore near the Hammond boat launch in the Columbia River went viral online.
The video was shot by Josh Robb, who was crabbing in the river west of Astoria last Saturday when his father-in-law noticed an injured seal in bloody water. Then the duo saw something else swimming close by – it was a 12-15 feet long white shark.
Robb immediately took his camera and started recording the shark in action. The shark came out of the bloody water to finish off the injured seal.

Residents in Hampton Bays who flocked to the Shinnecock Canal to see a massive fish kill on Monday were shocked at the sight of hundreds of thousands of dead bunker fish -- a two-foot deep wall of dead fish on the bay bottom.
The massive bunker kill, which may worsen today, occurred in the Shinnecock Canal and in Shinnecock Bay, because the fish ran out of oxygen.
Bob Walsh, one of the stunned spectators who lined the bridge to see the piles of dead fish, said sight saddened everyone.
As manatees are on the move in search for warmer waters to spend the upcoming harsh winter in, Florida’s wildlife officials have warned boaters that the whiskered marine mammals can pose a risk.
The Florida Fish & Wildlife Conservation Commission has urged boaters to slow down in areas in the sea where manatees are known to congregate. The commission has already confirmed 91 manatee deaths caused by boats so far this year.
Seasonal protection zones for the 1,000-pound marine mammals are set to take effect on coming Tuesday, Nov. 15, 2016.

A new study by a team of Berlin-based researchers has revealed that rats love to be tickled and they not only "giggle" but also have joyful jumping behavior.
When the researchers gave rats a 10-second tickle with a gloved hand, they found the rats enjoying an animal version of laughter. The rats not only enjoyed being tickled but also ran towards the gloved hand to be tickled again.

Seabirds eat floating trash like plastic bags and wrappers, many times with deadly consequences. But why these birds find plastic debris so appetizing has long been a brainteaser for marine biologists.
Now, a new study has suggested that seabirds mistakenly eat plastic floating in the ocean because it smells like food. A team of biologists from UC Davis have discovered the chemical clue to why seabirds eat plastic.

A team of neuroengineers at the Swiss Federal Institute of Technology developed an innovative set of wireless brain and spinal cord implants that successfully reversed leg paralysis in monkeys.
The researchers implanted the new device/chip in the brains of some monkeys with severed spinal cords. It allowed the monkey’s brain to bypass the injury by sending the instructions straight to the nerves that controls movements of legs.

Elephant poachers are hard at work in Africa and killings of the giant animals are continuing at an alarming pace, a new research revealed.
The sobering reality came into light after a team of researchers examined multiple seized shipments of elephant tusks and found that a big majority of those tusks came from African elephants that were killed within last three years.
Elephants are being killed just for their tusks/ivory. The sale as well as purchase of good made of ivory is illegal, but black markets exist across the globe.

Electron microscopes enables users to look at as minute things as viruses and bacteria, but existing microscopes are not able to provide colorful images because when things get too small, they go dark as well.
However, that problem has apparently solved as a team of researchers at the Center for Research in Biological Systems at UC San Diego have developed a new method that adds color to electron microscopic imagery.

A new research conducted by a team of scientists at Washington University School of Medicine in St. Louis has suggested a new way to reduce signs of aging.
The scientists supplemented healthy mice with a natural compound, dubbed NMN, and found that it reduced signs of aging such as gradual weight gain, declines in physical activity and loss of insulin sensitivity.
