Carpenter Ant Colonies in Florida Exhibit Pronounced Differences in Social Behavior

-Carpenter Ant Colonies in Florida Exhibit Pronounced Differences in Social Behavior

Not all, but little of you must have heard of the word Epigenetics, which means the study of stable, or persistent, changes in gene expression that occur without changes in DNA sequence. Epigenetic regulation has been observed to affect a variety of distinct traits in animals, including body size, aging, and behavior. In a new study published today in Science, a multi-institution team anchored at University of Pennsylvania found that carpenter ant colonies in Florida exhibit pronounced differences in social behavior throughout their lives.

Drought Threatens California’s Ecosystem

Drought Threatens California’s Ecosystem

Drought in California has led to draining of lakes, subsidizing of land and implementation of draconian water protocols. A research has revealed that between 2011 and 2015, about 58 million large trees over 3,861 square miles have suffered from water loss owing the biggest ever drought of the state. The research has been carried out by Carnegie Institution for Science at Stanford University. The drought is resulting in trees dying due to lack of water, which in turn will lead to revolutionary changes in ecosystem.

Local Divers in Japan capture Giant Squid on video

Local Divers in Japan capture Giant Squid on video

On Christmas Eve, fishermen in Toyama Bay of Japan were startled to see a 12-foot huge squid gliding near their marina for many hours, whereas local divers were able to record the cephalopod on video.

While speaking to the Japan Times, Mizuhashi Fisherina manager Tatsuya Wakasugi said that he was surprised to spot a living squid. The sightings of squid weren’t uncommon in the region, but fishermen generally detect dead ones tangled up in their nets when their colors fade.

13-foot-long cephalopod spotted next to a boat's moorings in Toyama Bay, located along Japan's west coast

13-foot-long cephalopod spotted next to a boat's moorings in Toyama Bay, located along Japan's west coast

Motherboard has reported that a 13-foot-long cephalopod has been observed and captured this week alongside a boat's moorings in Toyama Bay, present along west coast of Japan. Filmed on December 24, observers identified the squid as the uncommon Architeuthis a species generally only discovered washed up on beaches or dead on the sea surface.

Architeuthis are known to dwell in the ocean depths, and their life span is generally for up to 5 years. They grow rapidly and reproduce only once during its lifetime. The species can measure up to 43 feet long, at its biggest.

Geologists Estimate Massive Landslide at Oso Site to be 500 Years Old using Radioactive Dating Technique

Geologists Estimate Massive Landslide at Oso Site to be 500 Years Old using Radioactive Dating Technique

With the help of the radioactive dating technique, geologists at the University of Washington have found that the massive Rowan Landslide happened around 500 years ago. They analyzed the samples of wood buried in the Rowan landslide, just downstream of the Oso site, and the Headache Creek landslide, just upriver of the 2014 slide. With the help of new method to date all the previous landslides at a particular location, researchers found that the slopes in the area around Oso have collapsed on average once every 500 years.

Newly-discovered species of shark with jet black skin and faint glow is a master of stealth

Newly-discovered species of shark with jet black skin and faint glow is a master of stealth

A newly-discovered shark species with jet black skin and a faint glow is a stealth master. The shark has rightly given the common name ‘Ninja Lanternshark’. It belongs to the Pacific Ocean, living off the coast of Central America in deep waters from 2,742 feet to 4,734 feet, or 836 to 1443 meters.

A team of scientists have detailed the new found shark in a study carried by the Journal of the Ocean Science Foundation. One of the scientists in the team said that the animal owes its different name to Vicky Vásquez’s young cousins.

Newly discovered Fungus killing Ohia trees on Hawaii

Newly discovered Fungus killing Ohia trees on Hawaii

A fungus that has been discovered recently is killing a tree that’s very important for Hawaii’s water supply, endangered native birds and Hawaiian cultural traditions such as hula. The disease known as rapid ohia death has affected ohia lehua trees in hundreds, thousands on the Big Island.

It has reportedly affected 50% of the ohia trees throughout 6,000 acres of forest as of last year, but since then it’s believed to have spread more. So far, it’s been discovered mainly in Puna, but also in Kona and Kau. It hasn’t been found anywhere else worldwide.

Climate Change To Worsen Algae Blooms

Climate Change To Worsen Algae Blooms

NASA and the National Science Foundation jointly carried out a study, which shows that the temperatures of lakes across the globe are rising rapidly due to climate change. The study reveals that an average increase in the temperature of lakes in each decade is 0.61 degrees Fahrenheit. The rise in temperature will eventually aggravate algae blooms in the lakes.

Say No to California’s Dungeness crab This Christmas

Say No to California’s Dungeness crab This Christmas

The California Department of Fish and Wildlife on Tuesday confirmed the presence of domoic acid in the California’s Dungeness crab. The department also mentioned that people should strictly avoid consumption of the crab this Christmas.

Officials said that the level of acid found in crabs is worrisome and are far beyond the standards set by the California Department of Public Health for safe consumption.

California Department of Fish and Wildlife spokeswoman Jordan Traverso said in a statement that they have even found some crab samples coming without the presence of acid.

Two Critically Endangered species of sea snake found near Western Australia

Two critically endangered species of sea snakes have been spotted by researchers from James Cook University off the Western Australia coast. The snakes have been spotted after a period of more than fifteen years, according to research paper published recently in journal Biological Conservation. The only known habitat of the snakes is Ashmore Reef but they were spotted in the Ningaloo Reef, 1700 kilometers south of Ashmore Reef.
