Scientists find radioactive cesium, lowered blood cell counts in monkeys living near Fukushima. | Concept Pandora | Scoop.it From www.naturalnews.com - August 11, 2014 10:41 AM
(NaturalNews) Wild monkeys living near Fukushima, Japan, have detectable levels of radioactive cesium in their bodies, along with lowered blood cell counts that may indicate a hampered immune system, according to a study conducted by researchers from the Nippon Veterinary and Life Science University in Tokyo and published in the journal Scientific Reports on July 24.

In March 2011, a massive earthquake and tsunami caused multiple meltdowns at the Fukushima Daiichi nuclear power plant, leading to the release of radioactive elements including cesium into the surrounding environment.

"The findings are consistent with what our group had found with red blood cells and hemoglobin content for children living around Chernobyl," biologist Tim Mousseau of the University of South Carolina, who was not involved in the study, said to Live Science.

In 1986, a nuclear meltdown and explosion occurred at the Chernobyl nuclear power plant in Ukraine. In the ensuing years, much research has been done on the effects of the radiation released on humans, animals and other life in the region. Although comparable research at Fukushima has only just begun, scientists have already observed increased abnormalities in butterflies and negative effects on bird populations in the regions near the crippled Japanese plant.

Becoming a Marine Biologist, What is marine biology and what is a marine biologist?

From life.bio.sunysb.edu - May 5, 2014 8:03 PM

This is a harder question to answer than you may imagine! Marine biology is the field of knowledge relating to marine organisms. But what is a marine biologist? To many, it means being a dolphin trainer but to others it means managing a marine wildlife sanctuary. There are many answers to this question and I would say that a marine biologist is someone who works in some way in studying, observing, protecting, or managing marine organisms, be they microbe, plant or animal. If you study marine fish populations you are a marine biologist. If you manage a marine wildlife preserve and are concerned with protection of marine organisms there, then you too are a marine biologist. You know you're a marine biologist if you have a notebook or computer that you record information often about marine organisms. But you may also be a marine biologist if you are collecting sponges, looking for bioactive drugs. You may be counting them, doing DNA sequencing of them, observing them in the laboratory or making theoretical models predicting their abundance once fishing is decreased. So marine biologists do many things, but what they have in common is working with marine organisms.

'Blackfish' Creators Challenge SeaWorld to Open Debate - Ring Of Fire Radio: Robert Kennedy Jr, Mike Papantonio and Sam Seder

‘Blackfish’ Creators Challenge SeaWorld to Open DebatePosted on January 27, 2014 by Alisha Mims •

The director of the SeaWorld exposé, documentary film Blackfish, issued a challenge to the multi-billion dollar corporation. Director Gabriela Cowperthwaite asked SeaWorld to engage in a debate over issues addressed in the film after the company released a statement claiming the film is “propaganda” and untrue.

“As we have always maintained, we welcome an open and honest discussion with SeaWorld,” her statement on The Dodo says. “Unfortunately, Sea World’s business model is built on an antiquated form of animal entertainment which is dwindling in popularity and is no longer seen as humane by many people.”

Cowperthwaite also responded to SeaWorld’s assertion that Blackfish is “emotionally manipulative.” “We believe our audience is intelligent and in control of their own emotions,” she said. “We urge them to conduct additional research on topics such as SeaWorld’s separation of mothers and calves, the increased mortality rate of orcas in captivity, the impact of captivity on orca health, and the frequency of killer whales injuring one another and trainers.”

The filmmakers asked SeaWorld to address the following concerns:

“SeaWorld claims it does not capture killer whales in the wild.”

Evidence shows that SeaWorld has other groups capture wild animals for them. Cowperthwaite notes that SeaWorld is currently attempting to import wild-caught beluga whales from Russia. “‘Rescues’ are often veiled attempts to secure wild animals,” she said. “A whale called Morgan, rescued in the Netherlands in 2010, was not released as local law required but was instead transported to a park in Spain. When SeaWorld published documents listing its ‘assets,’ Morgan appeared as part of its ‘collection.’”

“Why SeaWorld stays relatively quiet on wild captures and killings.”

In the midst of the annual culling and slaughter of wild dolphins in Taiji, Japan as well as the capture of orcas and beluga whales in Russia, SeaWorld remains relatively quiet, despite touting claims of its conservation efforts. The company has vast resources and could be a strong voice against the cruel practices of killing and capturing wild cetaceans. SeaWorld obtained a pilot whale in 2010 that was reportedly captured in a drive hunt. Cowperthwaite notes that the company could easily provide evidence of how its beluga whales and other animals are captured, if there is nothing to hide.

14 extinct animals that could be resurrected: Tasmanian tiger.

14 extinct animals that could be resurrected: Tasmanian tiger. | Concept Pandora | Scoop.it From www.mnn.com - December 16, 2013 4:32 PM  
The Tasmanian tiger, or thylacine, native to Australia, was a remarkable animal that was the largest known carnivorous marsupial of modern times. The animals went extinct as recently as the 1930s, mostly due to the relentless efforts of bounty hunters.Because they went extinct so recently, specimens of the animal remain intact, pickled and preserved in museum jars. Some specimens that have been stuffed and displayed in museums may also still retain DNA. Projects to clone the thylacine are already well under way, and some of the animal's genes have already been successfully expressed in a mouse fetus after the genes were inserted into the mouse's genome.

Project #Coyote: News/Media: Petition Seeks to Reform Secretive Federal Agency That Kills Millions of Wild Animals.

Petition Seeks to Reform Secretive Federal Agency That Kills Millions of Wild Animals
‘Wildlife Services’ Shoots, Traps, Poisons Animals With Little Regulation, Public Accountability

 

WASHINGTON— The Center for Biological Diversity and allies petitioned the Obama administration today to reform the federal wildlife-killing agency known as “Wildlife Services,” which kills nearly 1.5 million coyotes, bears, otters, foxes, birds and other animals each year without any requirement to disclose its activities to the public. The secretive killing — which includes aerial gunning, traps and exploding poison caps — has gone on for decades with little public oversight or rules requiring the use of the best available science or techniques to reduce the deaths of nontarget animals.

Today's petition was filed with the U.S. Department of Agriculture, which oversees Wildlife Services.

“Wildlife Services is an out-of-control, rogue agency that shoots, snares and poisons more than a million native animals every year, many unintentionally — including at least 13 endangered species,” said Amy Atwood, a senior attorney at the Center for Biological Diversity and the primary author of the petition. “Despite calls for reform by members of Congress, scientists and the public, Wildlife Services is still operating without the kind of legally binding regulations that ensure transparency and accountability to the taxpaying American public, creating a free-for-all that should have been ended decades ago.”

The petition calls for the agency to:

Develop regulations to ensure use of the best science when determining whether action should be taken against animals;Avoid killing nontarget animals, including endangered species;Ensure ethical treatment of targeted animals and exhaustion of nonlethal means; andRequire release of reliable information to the public about the animals it kills.

 

A response to the petition is required by law; any decision is subject to review by the courts.

“For far too long Wildlife Services has run roughshod over America’s wildlife,” said Camilla Fox, founder and executive director of Project Coyote. “We call on the USDA to clean house and bring Wildlife Services into the modern era of predator conservation and stewardship by adopting rules that justify their actions and that allow for public input and the integration of ethics, economics and science-based ecology.”

Under various names, Wildlife Services has killed millions of animals since the early part of the 20th century, targeting native carnivores like coyotes and foxes, prairie dogs, birds and many other species at the behest of agribusiness interests. The agency contributed to the decline of gray wolves, Mexican wolves, black-footed ferrets, prairie dogs, and other species during the first half of the 1900s, and continues to impede their recovery today.

“Wildlife Services has long ignored sound science in establishing its priorities, instead taking its cues from ranchers and other ‘cooperators,’ ” noted Carson Barylak, federal policy advisor at the Animal Welfare Institute. “The influence of these private interests has taken precedence over the ecological principles that should be guiding the agency’s decisions, and wildlife is suffering as a result.”

According to the agency’s own figures, which likely underestimate the total death toll, the agency has killed more than 22 million native animals since 1996, representing 476 different species. The past five years have been some of the most active for the agency, with more than 1.5 million native animals killed per year. The agency reports that it kills an average of nearly 4,000 nontarget native animals annually, including at least 13 endangered species, such as Louisiana black bears, Mexican gray wolves, wood storks, Hawaiian stilts, island foxes and roseate terns.

“Wildlife Services has contributed to the endangerment of several species, such as wolves and grizzly bears, that play pivotal roles in the food chain and have been the subject of extensive recovery efforts,” said Atwood. “The agency is a major threat to North American wildlife and must be reined in and held accountable.”

Wildlife Services employees routinely engage in unlawful or inhumane activities, refusing to fire or discipline agency employees who are known to break the law or cause animal suffering. The agency is also notoriously secretive, shielding most of its activities from scrutiny, and routinely covering up a substantial portion of its animal killings.

Lead petitioners include Center for Biological Diversity, Project Coyote and the Animal Welfare Institute. The Animal Legal Defense Fund signed on as a supporting petitioner.

Baby Dinosaur Skeleton Unearthed in Canada. | Concept Pandora | Scoop.it From www.livescience.com - November 27, 2013 10:01 PM

The tiny, intact skeleton of a baby rhinoceroslike dinosaur has been unearthed in Canada.

The toddler was just 3 years old and 5 feet (1.5 meters) long when it wandered into a river near Alberta, Canada, and drowned about 70 million years ago. The beast was so well-preserved that some of its skin left impressions in the nearby rock.

The fossil is the smallest intact skeleton ever found from a group of horned, plant-eating dinosaurs known as ceratopsids, a group that includes the iconic Triceratops. [See Images of the Baby Dino Skeleton]

The Threats to Our Drinking Water By DAVID S. BECKMANAUG. 6, 2014. The New York Times.

The Threats to Our Drinking Water By DAVID S. BECKMANAUG. 6, 2014. The New York Times. | Concept Pandora | Scoop.it From myaccount.nytimes.com - August 11, 2014 10:50 AM

SAN FRANCISCO — THOSE of us who live in the United States are fortunate; generally we don’t have to give a lot of thought to the safety of our tap water. This makes our collective experience with water very different from that of hundreds of millions of people across the globe who lack access to clean water.

But twice this year the water supply for a major American city was interrupted for days by water pollution. In January, a chemical used in the processing of coal leaked from a ruptured storage tank into the Elk River, contaminating the water supply for about 300,000 people in and around Charleston, W.Va., the state’s capital and largest city. Then, last weekend, the water supply for over 400,000 people in Toledo, Ohio, was declared unsafe because of the presence of microcystin, a toxin released by algae blooms in nearby Lake Erie, the source of the city’s water.

While the circumstances in each situation are different, there are notable similarities. In each case, the pollution could not be adequately treated by the local water plants. Sudden “do not drink” (and, in some cases, “do not bathe”) warnings resulted. And in each case, activities in or near the communities caused, or partially caused, the problem. In Charleston, it was an upstream industrial spill; in Toledo, polluted runoff, including from agriculture, along the Great Lakes stoked the slimy, fluorescent algae blooms that sent residents flocking to supermarkets for bottled water.

Those events offer two important reminders about water in the United States.

Most of us will never visit the Arctic Circle — and the residents of this northernmost region are perfectly happy with that. We're not talking about Eskimos; we're talking about the animals that call the Arctic home. Though the subzero temperatures and rugged boreal forests may seem bleak and unforgiving, many species thrive in the frigid tundra of the Arctic Circle.

Some of these animals you will have seen before, like the polar bear or the snowy owl (pictured), while others are more exotic, like the "unicorn of the sea" or the Canada lynx. Learn more about these 13 animal representatives of the chilly Arctic Circle. (Text: Caroline Inge)

9 Things You Probably Didn't Know About Baby Dinosaurs.

9 Things You Probably Didn't Know About Baby Dinosaurs. | Concept Pandora | Scoop.it From mentalfloss.com - January 11, 2014 5:38 PM

We may not be able to directly observe them (with the obvious exception of Baby Sinclair), but newborn dinosaurs have given paleontologists around the globe magnificent insight into how these amazing creatures grew, lived, and reproduced nevertheless. Here are some of the most striking discoveries.

1. FETAL DINOSAURS FLEXED BEFORE HATCHING

Compelling evidence in the fossilized remains of embryonic Lufengosaurus (a species of long-necked Chinese herbivore) suggests that at least some unborn dinosaurs kicked and wriggled prior to breaking free of their shells, activities which stimulate bone growth inmodern-day mammals and birds.

2. A BABY DINOSAUR WAS “MUMMIFIED” IN ITALY

According to some experts, a juvenile Scipionyx (which was later nicknamed “Ciro”) may have been less than three weeks old when it perished some 113 million years ago in what’s now southern Italy. Its remains are so spectacularly preserved that joints, ligaments, and even internal organs are visible (including the stomach, which shows that Ciro was rather fond of smaller reptiles and the occasional fish), making the little creature one of the most complete dinosaur specimens known to science.

3. ADOLESCENT TRICERATOPS WENT THROUGH SOME SERIOUS SHAPE-SHIFTING

A positively adorable baby Triceratops skull discovered in 2006 helped complete a study on the iconic dinosaur’s growth patterns which yielded some surprising results (you can see the various phases here) as paleontologist Jack Horner explains in this eye-opening TED talk (skip to the 13:05 mark):

4. BABY DINOSAURS WERE OCCASIONALLY GOBBLED UP BY LARGE MAMMALS

When the opossum-sized Repenomamus robustus was first unearthed in 2000, the remains of an infant Psittacosaurus were found in its gut. For a dramatized recreation of its dino-guzzling antics, click here. 

5. … AND PREHISTORIC SNAKES

At over 11 feet in length, hefty serpents like Sanajeh indicus apparently had little difficulty invading the unguarded nests and eating the young of even the largest dinosaurs, as evidenced by a skeleton that was found coiled around a group of Titanosaur eggs back in 2010.

6. SOME HAD BUSHY TAILS

Known only from the fossilized carcass of a 28-inch hatchling, the species namedSciurumimus—or “squirrel mimic”— grew a layer of downy, feather-like structures on its tail at an early age, though it’s not likely that the pint-sized predator also went around collecting acorns.

7. BABY DINO TRACKS WERE FOUND IN COLORADO

The tennis-ball-sized footprints have been attributed to the dinosaur formerly known asBrontosaurus: Apatosaurus ajax, a massive herbivore which would have easily weighed in at over 20 tons when fully-grown. Curiously, these miniature tracks imply that their maker was running on its hind legs at the time, a feat its gargantuan parents most definitely couldn’t pull off.

8. “DUCK BILLED” DINOSAURS GREW FASTER THAN THEIR CARNIVOROUS COUNTERPARTS

Hatchling hadrosaurs (aka “duck-bills”) faced a particularly jarring challenge. A lack of any obvious defense mechanisms such as horns or plated armor is an unenviable situation for any potential prey item, but a 2008 study found that the seemingly-helpless animals defended themselves by simply outgrowing their predators, sometimes reaching full size at three to five times the rate of local Tyrannosaurs.

9. SOME DINOSAURS MAY HAVE LAID THEIR EGGS IN OTHER SPECIES’ NESTS

Egg-laying can be a sneaky business. Rather than go through the effort of raising their own young, some modern birds such as the European Cuckoo simply deposit theirs in the nest of unsuspecting songbirds to trick the unwitting victims into feeding and nurturing the crafty avian’s young.

While it’s a speculative conclusion, Mark Norell of the American Museum of Natural History has turned to this Machiavellian strategy as a potential explanation for why a pair ofVelociraptor-like hatchlings (or possibly embryos) were found in an Oviraptor’s nest (though Norell also offered some more conservative conclusions, such as that the mother simply made a snack of the two raptors).

Cuttlefish camouflage: A new method for studying the masters of disguise.

Cuttlefish camouflage: A new method for studying the masters of disguise. | Concept Pandora | Scoop.it From oceanbites.org - December 16, 2013 11:28 AM
Squid, octopus, and cuttlefish are considered masters of disguise in the ocean. But how do they do it? A recent study by Goodwin and Tublitz tested a new technique to study cuttlefish camouflage using image analysis software.

 

How do cuttlefish camouflage?

Cuttlefish, like other cephalopods, have chromatophores.  Chromatophores are pigmented organs controlled by muscles that expand and contract to change the size of each cell.  More specifically, chromatophores are neuromuscular organs that respond to electric impulses, much like our brains.

A group of researchers, including Dr. Roger Hanlon from the Marine Biological Labs in Woods Hole, Massachusetts, created a video to demonstrate the neuromuscular function of squid chromatophores in response to music played from an iPod (Wardill et al. 2012).  The video also links to a TED talk demonstrating the same concept applied to a cockroach leg.

Together, these cells create fantastic patterns to mimic a variety of backgrounds.  For more information and examples of cuttlefish camouflage, check out this 2008 video interview of Dr. Hanlon (New York Times).  As Dr. Hanlon indicates in the interview, there is a lot we don’t know about cephalopod camouflage.  Furthermore, the techniques to answer many research questions have not been developed.

About the project

The authors, Goodwin and Tublitz, tested a new method for measuring chromatophore activity in European cuttlefish. This method would help develop answers to questions about how chromatophores work and why chromatophores of different color behave differently.  Researchers developed computer software to analyze images of chromatophores and compared computer results to techniques used in prior studies

Methods

The researchers received cuttlefish eggs from The Smithsonian Aquarium (Washington, DC) and raised them to adulthood.  They proceeded to extract samples of fin tissue from six of the cuttlefish, without killing them.  To induce changes in chromatophore shapes and sizes, each tissue sample was washed with artificial sea water for 1.5 minutes, followed by a 5-minute application of a neuropeptide solution, and another 3-minute artificial sea water wash.  Throughout this, images were collected at 40 frames per second.

Pictures of the tissues were then assessed in image analysis software.  Chromatophores were first manually separated into color categories (black, red-brown, and yellow).  Red-brown and black were ultimately grouped together as “red-black” because the colors could not be distinguished from one another.

A comparison of red-black and yellow chromatophores, using pixel data, detected differences between the two color categories accurately by setting thresholds for red, green, and black color intensity in each category.  These threshold values were then used in developing the new image analysis program.

The program was created to track chromatophores over several images by a process called segmentation (see Figure 1). Using this segmentation process, the computer can isolate each chromatophore in an image to assess its color category (red-black or yellow), and size.  The program would then track the changes in that chromatophore over consecutive images to record changes in size.

Why Eerie Green Lightning Zapped an Erupting Volcano.

Why Eerie Green Lightning Zapped an Erupting Volcano. | Concept Pandora | Scoop.it From www.livescience.com - December 10, 2013 7:20 PM

.

SAN FRANCISCO — A storm of charged particles coursing through a volcanic ash cloud sparked the spectacular green lightning seen at Chile's Chaiten Volcano in 2008, a researcher said here Monday (Dec. 9) at the annual meeting of the American Geophysical Union.

The green lightning revealed an electrical dance normally hidden inside thunderclouds, Arthur Few, an atmospheric scientist at Rice University in Houston, said. "It probably occurs in all thunderstorms, but you never see it," Few said. "Because of the structure of charges in a volcano cloud, it's on the outside of the cloud."

Two spectacular photographs, snapped when Chaiten erupted in May 2008, recently caught Few's eye when he was investigating volcanic lighting. The volcano looms over the Andes about 800 miles (1,285 kilometers) south of Santiago, Chile, and erupted on May 2 of that year after lying dormant for hundreds of years. A retired professor, Few said he was driven to explain the phenomenon simply out of curiosity.

Did Comet ISON Survive? Scientists See Tiny Hope | TalkingPointsMemo.com

Did Comet ISON Survive? Scientists See Tiny Hope | TalkingPointsMemo.com | Concept Pandora | Scoop.it From talkingpointsmemo.com - November 30, 2013 10:27 AM

A comet that gained an earthly following because of its bright tail visible from space was initially declared dead after essentially grazing the sun. Now, there is a silver of hope that Comet ISON may have survived.

 

New images, basically faint smudges on a screen, being analyzed Friday showed a streak of light moving away from the sun that some said could indicate it wasn't game over just yet.

 

"It certainly appears as if there is an object there that is emitting material," said Alan Fitzsimmons, an astronomer at Queens University in Belfast, Northern Ireland.

 

Basically a dirty snowball from the fringes of the solar system, scientists had pronounced Comet ISON dead when it came within 1 million miles (1.6 million kilometers) of the sun Thursday.

 

Some sky gazers speculated early on that it might become the comet of the century because of its brightness, although expectations dimmed over time. But it wouldn't be all bad news if the 4.5-billion-year-old space rock broke up into pieces, because some scientists say they might be able to study them and learn more about comets.

 

The European Space Agency, which had declared ISON's death on Twitter late Thursday, was backtracking early Friday, saying the comet "continues to surprise."

 

Comet ISON was first spotted by a Russian telescope in September last year, and became something of celestial flash in the pan this week for its vivid tail -- visible by the naked eye -- and compelling backstory of impending doom.

 

The comet was two-thirds of a mile wide as it got within 1 million miles (1.6 million kilometers) of the sun, which in space terms basically means grazing it.

Trilobites ("three-lobes") are extinct arthropods that form the class Trilobita. They appeared in the Early Cambrian period and flourished throughout the lower Paleozoic era before beginning a drawn-out decline to extinction when, during the Late Devonian extinction, all trilobite orders, with the sole exception of Proetida, died out. The last of the trilobites disappeared at the end of the Permian about 250 million years ago.
