    The moon jellyfish is commonly found around the coastlines of Britain. They're known for their translucent white colour and gentle swimming movements. Until now, they were thought to have very few predators. But new findings published today in the journal Royal Society Open Science reveal that they are a veritable feast for a number of fish species. Lead researcher Philip Lamb, a PhD student in UEA's School of Biological Sciences, said: "Localised outbreaks of jellyfish cause a variety of ecological and economic problems such as overrunning fish farms and damaging revenues from tourism. But until now there has been little...

    Scientists, including one of Indian origin, have found that jellyfish go into a sleep-like state, making them the first animals without a brain or central nervous system to do so. The findings push the origin of sleep further down the evolutionary tree of life - to before the emergence of a centralised nervous system. "It is the first example of sleep in animals without a brain," said Howard Hughes, from California Institute of Technology in the US. Researchers studied Cassiopea, a mostly stationary jellyfish native to mudflats, mangrove swamps, and other warm, shallow waters. The jellfish were kept in tanks...

    Marine researchers have discovered a strange alien-like creature while exploring the underwater world found in the deepest ocean trench on Earth. A team of scientists from the National Oceanic and Atmospheric Administration (NOAA) spotted the hydromedusa jellyfish during an expedition to the Mariana Trench in the Pacific. The sea creature was captured on film after it swam close to the surface of the ocean near the agency's research ship, the "Okeanos Explorer." Based on the team's observations, this new jellyfish species shares similar features with those of Crossota genus, which are known to spend the majority of their existence gliding...

    A lamb that was genetically modified with jellyfish genes for advanced research was sold to a slaughterhouse for meat in France, according to European news accounts. An investigation to find out how the genetically-altered animal ended up as meat is underway, according to Le Parisien, the French newspaper that broke the story. "Rubis, the lamb, was found on a plate. Who ate her? No one knows. All that's known is the meat left a French slaughterhouse in November 2014" according to Le Parisien. The story states Rubis came from a program started in 2009 called "Green Mutton" within the scientific...
  • Has Stanford University found a cure for Alzheimer's disease?

    The Telegraph ^ | 12/08/2014 | By Sarah Knapton, Science Editor
    Alzheimer's could be prevented and even cured by boosting the brain's own immune response, scientists at Stanford University believe. Researchers discovered that nerve cells die because cells which are supposed to clear the brain of bacteria, viruses and dangerous deposits, stop working. These cells, called 'microglia' function well when people are young, but when they age, a single protein called EP2 stops them operating efficiently. Now scientists have shown that blocking the protein allows the microglia to function normally again so they can hoover up the dangerous sticky amyloid-beta plaques which damage nerve cells in Alzheimer's disease. The researchers found...
  • Norway Fjord Invaded by Monster Jellyfish

    Norway's Beitstadfjord has been so severely invaded by monster deep sea jellyfish that, just two years since their arrival, they have driven out all of the local fish. The innermost arm of the Trondheimsfjord now holds an estimated 40,000 tonnes of the helmet jellyfish, only a few years after the fiery red peril first appeared in its waters. According to Norway's VG newspaper, Jarle Mork, a researcher at NTNU in Trondheim, caught vast quantities of the slimy animal in a single trawl. "We took up 3.5 tons of monster jellyfish in under ten minutes," he said. "There was a tremendous...

    Comb Jelly Genome Gums Up Evolution by Jeffrey Tomkins, Ph.D. * Comb jellies (ctenophores) look like disco balls with flashing lights that dance and spin as they float around the ocean. These creatures are so fascinating that one neuroscientist likened them to "aliens who've come to earth."1,2 The genome of comb jellies has been sequenced, and it's as alien as the creature looks—utterly defying all predictions about its evolutionary origins.3 Even prior to recent advances in genome sequencing, comb jellies perplexed evolutionists. While they resemble a jelly fish in some ways, they have complex nervous systems that detect light, sense...

    In a prehistoric version of "the chicken or the egg" question, researchers have long debated which animal group came first. A traditional view pegs sponges—marine creatures that look more like rocks or corals—as our ancient ancestors. But a new genetic study is stirring the waters, suggesting comb jellies, gelatinous marine animals that look similar to jellyfish, are actually the first animals to have evolved over 600 million years ago.

    A regular day at the beach led to a surprising scientific discovery for one family in Australia last month—local resident Richard Lim and his family spotted a shockingly large jellyfish at a beach in Howden, a small town in Tasmania.The family did what anyone would do—take photos, of course—but they also shared the images with Lisa-ann Gershwin, a research scientist and jellyfish expert at the Commonwealth Scientific and Industrial Research Organization (CSIRO), Australia’s national science agency. Gershwin’s first reaction upon seeing the photos? Pure shock, despite the fact that she’d already known about the new species. “I had seen what...

    A nuclear power station in eastern Scotland had to shut down its reactors after "high volumes" of jellyfish were found on its seawater filter screens, the operating company said Thursday. "Both units at Torness power station were manually shut down on 28 June, due to the high volumes of jelly fish fouling the cooling water screens," said a statement from EDF Energy, which runs the power station near Dunbar. It explained that the shutdown was purely a precautionary measure and insisted that "at no time was there a danger to the public", nor had there been any impact on the...

    From the team that brought you Blackwater and the pre-9/11 counterterrorism program Able Danger comes “Jellyfish Intelligence.” That’s the name a group of former US intelligence officials and executives from the controversial security firm have chosen for a new private outfit that offers “predictive intelligence” for Fortune 500 corporations and senior-level executives and that aims to “protect human lives and their business interests throughout the world. The company blends traditional models of a strategic consulting firm with what it claims is an extensive network of human sources—people who, in an official context, would be called spies.

    Direct observations of these creatures from submersibles are very rare. It has been previously videoed by scientists off the Pacific coast of the US and by ROVs off Japan. However, this is the first time the giant jelly has been recorded in the Gulf of Mexico. The researchers reported four chance encounters with jellyfish between 2005 and 2009, during the routine underwater work the energy companies carried out on their underwater structures. The footage shows the reddish purple coloured jellyfish at depths ranging from 996m to 1747m. Trap prey The scientists observed the jellyfish attaching itself to the subsea equipment...

    President Barack Obama dropped his threat to bypass the Senate and install nominees to their positions through recess appointments -- at least for now. Recess appointments can be made while the Senate is out of session and are a way for presidents to get around the need for a confirmation vote. The president said in a statement Thursday evening that he is encouraged by confirmation earlier in the day of 27 high-level nominees. On Tuesday, Obama threatened to make the recess appointments to get around senators who had placed "holds" on his nominees, which prevent, or at least delay, the...

    The Senate confirmed a huge group of administration nominees on Thursday, following a tense exchange between President Barack Obama and Senate Minority Leader Mitch McConnell (R-Ky.). At a White House meeting with bipartisan congressional leaders on Tuesday, Obama warned that he would make recess appointments if the logjam over nominees wasn’t broken before the Senate left for the Presidents’ Day break. “Mitch, this is unprecedented,” the president said, gesturing forcefully on the Cabinet Room table, according to aides. “If you don’t move any, I’m going to do some [recess] appointments.” The 27 confirmations mean no recess appointments will be needed...

    In the black depths of the frigid Arctic Ocean, scientists on a 2005 expedition found a splash of color: The brilliant, blood-red Crossota norvegica jellyfish (pictured). The creature was spotted by a remotely operated vehicle 8,530 feet (2,600 meters) underwater during a two-month National Oceanic and Atmospheric Administration (NOAA) expedition to the Canada Basin, the deepest and least explored part of the Arctic waters. Though C. norvegica is not a new species, several new deep-sea animals were discovered during the expedition--some of which were announced in recent research papers in 2009.

    Sorry, kids—scientists have not discovered the first known bubblegum-blowing sea creature. But they have found the only known corals to eat adult jellyfish, a new study says. Opening wide--yes, that's a mouth--a mushroom coral ingests a roughly 4-and-a-half-inch-wide (12-centimeter) moon jellyfish (pictured) in the Red Sea in March 2009. And this coral wasn't alone. The study, led by scientists from Israel's Bar-Ilan University and Tel Aviv University, witnessed other corals dining on the jellyfish. Marine ecologist Jennifer Smith, who wasn't part of the study, agreed the find was unique, though she's "not entirely surprised." Mushroom corals, which have soft bodies,...
