Thorny skate won’t get protection under ESA

Thorny skate won’t get protection under ESA

The thorny skate, a species of fish that mainly lives near the bottom of the coastline of North Atlantic Ocean, will not get protection under the Endangered Species Act (ESA), the federal government agency has declared.

Various environmental groups and wildlife advocates had urged the federal authorities to add the thorny skate species to the endangered species list because the species’ population has declined significantly in the northwest Atlantic Ocean.

Poachers killed 25,000 elephants in Africa’s Minkebe National Park: survey

Poachers killed 25,000 elephants in Africa’s Minkébé National Park: survey

Poachers have killed as many as 25,000 forest elephants in Africa’s Minkebe National Park within a decade, according to a fresh survey by Duke University researchers.

Lead researcher John Poulson, an assistant professor of tropical ecology at Duke University, wrote in the newly published study that population of elephants in the national park, which has been a key sanctuary for the species, slipped 78 per cent from 2004 to 2014.

New Zealand beach turns into a whale grave

New Zealand beach turns into a whale grave

Around a week ago, a New Zealand beach became a distressing grave site when hundreds of pilot whales became stranded on it and many of them died.

The New Zealand the Department of Conservation (DOC) confirmed that more than 600 pilot whales became stranded on the Farewell Spit at the tip of the South Island. Hundreds of volunteers worked with DOC workers to save the whales, but they could save only half of them. More than 300 whales died at the beach.

Scientists discover pollutants 10,000 meters deep in the Pacific Ocean

Scientists discover pollutants 10,000 meters deep in the Pacific Ocean

A new research has revealed the presence of chemical pollutants PCBs and PBDEs in some of the Pacific Ocean’s deepest trenches that were previously thought to be unharmed by human influence.

Scientists were surprised to find PCBs, PBDEs and other chemical pollutants in high concentrations in deep sea ecosystems because these pollutants have been banned since the 1970s.

Japanese scientists develop robotic pollinator

Japanese scientists develop robotic pollinator

A team of Japanese scientists has successfully turned a small remote-controlled drone into a honey bee-like pollinator by attaching horsehairs layered with a special, sticky gel to its underbelly.

Flowers looking to receive pollen from their male parts into another bloom’s female parts often require an envoy to carry pollen. Those third players, such as honey bees, are called as pollinators.

Fish-scale gecko escapes predators’ grip by shedding scales and skin

Fish-scale gecko escapes predators’ grip by shedding scales and skin

Researchers have discovered a new type of gecko, an evasive little lizard that can escape predators’ grip by shedding its scales as well as skin.

The new species, dubbed Geckolepis megalepis, has the biggest scales of any fish-scale gecko, some of which measure nearly 8 per cent of its total body length. A team of researchers, led by Mark D. Scherz of Ludwig Maximilian University of Munich, discovered it northern Madagascar’s limestone karst.

Viscoelastic Tongue Helps Frogs to Catch Prey Easily: Research

Viscoelastic Tongue Helps Frogs to Catch Prey Easily: Research

Frogs use a viscoelastic tongue and non-Newtonian saliva to catch prey, as per a new research paper from researchers at Georgia Institute of Technology has informed. The research paper has been published in Journal of The Royal Society Interface. Frogs use their whip-like tongue and it hits the prey with a strong force. The tongue is very soft and a unique reversible saliva offers the stickiness to this action, which helps frogs to trap their prey. The swift action and stickiness doesn’t give a chance to the prey to escape. Before the prey knows it, it is already in mouth of the frog.

Frogs use sticky spit to catch prey

Frogs turn to sticky spit to catch prey

Frog’s sticky spit is one of the catchiest spits on the planet, and it is tailor-made to grab bugs, according to a new research on frog saliva.

Led by Alexis Noel, a PhD student at the Georgia Institute of Technology, a team of researchers used high-speed photography as well as an instrument known as Rheometer to analyze saliva collected form 15 frogs under prey-capturing conditions.

Explaining how he collected frog saliva, Noel said he got fifteen frogs, and scraped their tongues for hours. He called it a “pretty disgusting” experience.

Researchers identify chemical compounds that give tomatoes distinctive taste

Researchers identify chemical compounds that give tomatoes distinctive taste

A team of American researchers claimed to have identified the chemical compounds that give a great tomato its distinctive sweet, earthy taste. They have also pin pointed the genes that code for these chemicals and where these genes can be found in the tomato genome.

University of Florida researchers said their study could help breeders create tomatoes that would be hardy enough to survive the long and demanding journey from fields to kitchens without sacrificing flavor and taste.

Tiny moth named after Donald Trump

Tiny moth named after Donald Trump

A recently discovered tiny moth that has helmet-like cluster of yellow-white scales atop its head has been named after President-elect Donald Trump, the journal ZooKeys reported.

Dr. Vazrick Nazari, an evolutionary biologist from Ottowa, Canada, said the moth with a wingspan of merely 0.4 inches encouraged them to name it Neopalpa donaldtrumpi because it has yellow and white scales on its head resembling Trump’s signature hairstyle.
