Mysterious Call from Mariana Trench Could Have been from Minke Whale: Research

Mysterious call from the depths of Mariana Trench recorded earlier, has been identified as per a new research paper published by Oregon State University. Researchers have been trying to figure out the source of that mysterious sound recorded from Mariana Trench. The research team claims that the sound could have been a call from minke whale, a type of baleen whale. The call recorded by researchers from Mariana Trench has frequency range from 38 hertz to 8,000 hertz.

The deep-sea thriving pointy-nosed blue chimaera or ghost shark has been captured on camera for the first time, off the coasts of Hawaii and California. The pointy-nosed blue chimaera is considered rare and it has been earlier found only in the southwestern Pacific Ocean. Ghost sharks have very strange features and as they live in deep-sea, they are with pale eyes.

A video captured by a wildlife photographer on Monterey Bay Whale Watch tour shows a group of killer whales eating a still-living shark. The video shared by wildlife photographer Slater Moore showcases the speed at which killer whales finished up the shark.

Mr. Moore captured the amazing footage with his drone mounted camera. In video shows two adult female killer whales and two calves finishing up a still-living shark. It is quite rare to spot whales attacking a shark as they usually hunt and feed underwater.

Vocal Tract of Monkeys Can Deal With Speech but Brain not developed enough: Research

Vocal Tract of Monkeys Can Deal With Speech but Brain not developed enough: Research

Monkey have well developed vocal tract that can help them human-like sounds but their brain isn’t enough developed for speech, as per a new research. The study teams from Europe and the United States analyzed throat and mouth of macaque monkeys with x-ray video to check if they have vocal tract ready for human-like speech. With the help of a computer model, the research team tested what the sounds would be like, if monkey brain was replaced with human brain.

Lack of right wiring in primates’ brains prevents them from producing human-like speech

Lack of right wiring in primates’ brains prevents them from producing human-like speech

Monkeys have a vocal tract capable of producing human-like speech but they are unable to produce words because they lack the right wiring in their brains, according to a new study.

Researchers have long been intrigued by primates’ failure to talk like humans. On Friday, a group of researchers reported that their study suggested that monkeys have the required vocal tract but they don’t have the right wiring required to produce words.

New bird study has implications for robots & drones: researchers say

New bird study has implications for robots & drones: researchers say

At the time of lift off, birds’ wings generate tiny, circular currents of air known as wingtip vortices. A new study allowed a group of researchers to visualize and examine these wingtip vortices, and they discovered that found that the actual way the air moves is different from what is commonly thought based on theoretical calculations.

Rare weasel species returns to Mount Rainier National Park

A large crowd gathered at the Mount Rainier National Park in Washington State late last week to herald the return of a rare weasel species that had been missing in the area for the last seven decades.

A total of 10 Pacific fishers, which had been trapped in British Columbia, were set free at Mount Rainier National Park as part of wildlife officials’ efforts to reintroduce the native species to its historical range.

Australia’s Great Barrier Reef suffers its worst coral die-off

Australia’s Great Barrier Reef suffers its worst coral die-off

The Great Barrier Reef in Australia suffered its worst coral die-off this year as warmer seas killed more than two-thirds of a 700-kilometer (435 miles) stretch of coral within the last nine-month period, researchers announced on Monday.

The Australian Research Council’s Centre of Excellence for Coral Reef Studies said in its latest report that the reef’s northern region, off the coast of Queensland, Australia, suffered a loss of 67 per cent of its shallow-water corals during the last eight to nine months.

American Saltmarsh Sparrow Could Face Extinction in 50 Years: Report

American Saltmarsh Sparrow Could Face Extinction in 50 Years: Report

The saltmarsh sparrow could face extinction over next five decades, as per a new report issued by the Connecticut Audubon Society. The society has warned that saltmarsh sparrows have been facing decline in population since 1998 and the average annual decline has been estimated at 9 percent. The nesting regions for sparrows have decreased and they also face other challenges.
