Two conjoined Nile Tilapia fish, dubbed “Siamese Twin”, swim in a small aquarium in Bangkok October 3, 2008. They are both eight months old and share part of the skin together. The bigger fish tends to protect the smaller one from harm while the smaller one looks for food at the bottom of the aquarium.

Red chlorophyll

Author: Dr. Mobusu  //  Category: Biology, Dr. Mobusu, Science

Red chlorophyll is like green chlorophyll but it is red. Hey, don’t expect poetry, there isn’t much you can say introducing it that you shouldn’t already know! There is red, green, and blue chlorophyll, but this is a new version that does Red Edge. Which means absorbs the light near the infrared spectrum. That means if you were wearing Infrared goggles, you would just see a big black spot. I am sure you want to know what horrible thing I am using this for…but it is TOP SECRET!!!! MuHAHAHAHAHAHAHA!!!!!!

Living On ‘The Red Edge’: Rare Form Of Chlorophyll Discovered In Newly Sequenced Bacterium

ScienceDaily (Feb. 11, 2008) — Researchers at Washington University in St. Louis and Arizona State University have sequenced the genome of a rare bacterium that harvests light energy by making an even rarer form of chlorophyll, chlorophyll d. Chlorophyll d absorbs “red edge,” near infrared, long wave length light, invisible to the naked eye.

In so doing, the cyanobacterium Acaryochloris marina, competes with virtually no other plant or bacterium in the world for sunlight. As a result, its genome is massive for a cyanobacterium, comprising 8.3 million base pairs, and sophisticated. The genome is among the very largest of 55 cyanobacterial strains in the world sequenced thus far, and it is the first chlorophyll d –containing organism to be sequenced .

Robert Blankenship. Ph.D., Lucille P. Markey Distinguished Professor in Arts & Sciences at Washington University, and principal investigator of the project, said with every gene of Acaryochloris marina now sequenced and annotated, the immediate goal is to find the enzyme that causes a chemical structure change in chlorophyll d, making it different from primarily chlorophyll a, and b, but also from about nine other forms of chlorophyll.

“The synthesis of chlorophyll by an organism is complex, involving 17 different steps in all,” Blankenship said. “Some place near the end of this process an enzyme transforms a vinyl group to a formyl group to make chlorophyll d. This transformation of chemical forms is not known in any other chlorophyll molecules.”

Blankenship said he and his collaborators have some candidate genes they will test. They hope to insert these genes into an organism that makes just chlorophyll a. If the organism learns to synthesize chlorophyll d with one of the genes, the mystery of chlorophyll d synthesis will be solved, and then the excitement will begin.

Blankenship and his colleagues from both institutions published a paper on their work in the Feb. 4, online edition of the Proceedings of the National Academy of Sciences. The work was supported by the National Science Foundation and also involved collaborators from Australia and Japan. Three Washington University undergraduate students and one graduate student participated in the project, as well as other research personnel.

Harvesting solar power through plants or other organisms that would be genetically altered with the chlorophyll d gene could make them solar power factories that generate and store solar energy. Consider a seven-foot tall corn plant genetically tailored with the chlorophyll d gene to be expressed at the very base of the stalk. While the rest of the plant synthesized chlorophyll a, absorbing short wave light, the base is absorbing “red edge” light in the 710 nanometer range. Energy could be stored in the base without competing with any other part of the plant for photosynthesis, as the rest only makes chlorophyll a. Also, the altered corn using the chlorophyll d gene could become a super plant because of its enhanced ability to harness energy from the sun.

That model is similar to how Acaryochloris marina actually operates in the South Pacific, specifically Australia’s Great Barrier Reef. Discovered just 11 years ago, the cyanobacterium lives in a symbiotic relationship with a sponge-like marine animal popularly called a sea squirt . The Acaryochloris marina lives beneath the sea squirt, which is a marine animal that lives attached to rocks just below the surface of the water. The cyanobacterium absorbs “red edge” light through the tissues of its pal the sea squirt.

The genome, said Blankenship, is ” fat and happy. Acaryochloris marina lies down there using that far red light that no one else can use. The organism has never been under very strong selection pressure to be lean and mean like other bacteria are. It’s kind of in a sweet spot. Living in this environment is what allowed it to have such dramatic genome expansion.”

Blankenship said that once the gene that causes the late-step chemical transformation is found and inserted successfully into other plants or organisms, that it could potentially represent a five percent increase in available light for organisms to use.

“We now have genetic information on a unique organism that makes this type of pigment that no other organism does,” Blankenship said. “We don’t know what all the genes do by any means. But we’ve just begun the analysis. When we find the chlorophyll d enzyme and then look into transferring it into other organisms, we’ll be working to extend the range of potentially useful photosynthesis radiation.’

Today’s explaination for Junk DNA is…

Author: Dr. Mobusu  //  Category: Biology, Dr. Mobusu, Science

Junk DNA seems to have every explanation on the planet for what it is for. And they are all wrong. Everyone knows Junk DNA is really spare parts carried in case DNA Vampires from the planet Neptune attack the Earth again. That way, you have spare DNA to keep yourself alive long enough to defeat them yet again. The explosive addition of microRNAs talked about in this article is just the result of one such DNA Vampire attack and the explosive growth in DNA diversity that follows after the vampires’ defeat.

‘Junk DNA’ Can Explain Origin And Complexity Of Vertebrates, Study Suggests

ScienceDaily (Feb. 12, 2008) Dartmouth College researchers and colleagues from the University of Bristol in the U.K. have traced the beginnings of complex life, i.e. vertebrates, to microRNA, sometimes referred to as ‘junk DNA.’ The researchers argue that the evolution of microRNAs, which regulate gene expression, are behind the origin of early vertebrates.

Vertebrates - animals such as humans that possess a backbone - are the most anatomically and genetically complex of all organisms, but explaining how they achieved this complexity has vexed scientists since the conception of evolutionary theory.

The team studied the genomics of primitive living fishes, such as sharks and lampreys, and their spineless relatives, like the sea squirt. By reconstructing the acquisition history of microRNAs shared between human and mice, the researchers determined that the highest rate of microRNA innovation in the vertebrate lineage occurred before the divergence between the living jawless fishes like the lamprey and the jawed fishes like the shark, but after the divergence of vertebrates from their invertebrate chordate relatives, such as the sea squirt.

Alysha Heimberg of Dartmouth College and her colleagues showed that microRNAs, a class of tiny molecules only recently discovered residing within what has usually been considered ‘junk DNA’, are hugely diverse in even the most lowly of vertebrates, but relatively few are found in the genomes of our invertebrate relatives.

She explained: “There was an explosive increase in the number of new microRNAs added to the genome of vertebrates and this is unparalleled in evolutionary history.”

Stop messing with my turtles!

It seems some jerk scientists have stumbled across my private stash of Swinhoe’s turtles and are now hailing their rediscovery. These are my private stash! I’m saving them for a special experiment, but now I have to deal with some conservation nutjobs who haven’t figures out how to mass clone endangered animals. For shame! If I don’t save the wee turtles, who will?

Almost Extinct Turtle Discovered Living In Wild In Northern Vietnam

ScienceDaily (Apr. 19, 2008) — “Swinhoe’s soft-shell turtle” was thought to be extinct in nature. Cleveland Metroparks Zoo has just announced the discovery of a critically endangered turtle in northern Vietnam that previously was thought to be extinct in the wild. Experts from the Zoo’s Asian Turtle Program confirmed that they have identified the only known living specimen of a Swinhoe’s soft-shell turtle (Rafetus swinhoei) in nature.

After three years of searching lakes and wetlands along the Red River in northern Vietnam, researchers sponsored by Cleveland Metroparks Zoo and the Cleveland Zoological Society, turned their focus to a lake just west of Hanoi, where local residents claimed to have occasionally seen the gigantic soft-shell turtle. Field biologist Nguyen Xuan Thuan, with Education for Nature in Vietnam, found and photographed the turtle as it basked on the lake’s surface, allowing scientists to confirm the animal was the extremely rare Swinhoe’s turtle.

This is an incredibly important discovery because the Swinhoe’s turtle is one of the most critically endangered species of turtle in the world,” said Doug Hendrie, the Vietnam-based coordinator of Cleveland Metroparks Zoo’s Asian Turtle Program. “This species has legendary status among the people of Vietnam, so this is perhaps an opportunity for the legend to live on.”

Drop the lawsuits, please! I totally didn’t knock up that sea dragon guy, using artificial eggs and sperm to make him pregnant. He isn’t breeding an army of sea dragons which I will use to threaten offshore oil rigs in exchange for extortion money. There will not be a herd of giant sea dragons roaming the ocean that will attack shipping lanes for cheap goods, hijack oil tankers, and sink Greenpeace vessels for fun. And any news reports you see to the contrary are all a pack of lies. Trust your Dr. Mobusu!

Endangered sea dragon at Ga. aquarium pregnant

Thu Jun 12, 3:19 PM ET

ATLANTA - A weedy sea dragon at the Georgia Aquarium has something to celebrate this Father’s Day. One of the rare creatures is pregnant for only the third time ever at a U.S. aquarium, aquarium officials said. But don’t look for the expectant mom — dads carry the eggs in this family.

The aquarium’s sea dragon has about 70 fertilized eggs — which look like small red grapes — attached to his tail. He is expected to give birth in early to mid-July, said Kerry Gladish, a biologist at the aquarium.

He was made a unicorn on purpose, for one reason: for kicks! That’s right, what’s better than making freaks of nature? NOTHING! The freakier the better, and this guy is totally freaked up! It rules. Even that new game Spore is all about making freaks of nature. Freaks rule, normals drool. Expect a bunch more unicorns to pop up in the animal kingdom pretty soon, as long as the pregnancies come to term. Nothing burst my bubble faster than spontaneous abortions of my freaks of natures. So many freaks who shall never get to get their freak on. :(

Single-horned ‘Unicorn’ deer found in Italy

By MARTA FALCONI, Associated Press Writer Wed Jun 11, 3:06 PM ET

ROME - A deer with a single horn in the center of its head — much like the fabled, mythical unicorn — has been spotted in a nature preserve in Italy, park officials said Wednesday.

“This is fantasy becoming reality,” Gilberto Tozzi, director of the Center of Natural Sciences in Prato, told The Associated Press. “The unicorn has always been a mythological animal.”

The 1-year-old Roe Deer — nicknamed “Unicorn” — was born in captivity in the research center’s park in the Tuscan town of Prato, near Florence, Tozzi said.

He is believed to have been born with a genetic flaw; his twin has two horns.

Okay, so maybe I ate a few of them from time to time on special occasions. It wasn’t that many! I can’t help it if they are delicious! They should evolve worst tasting meat. How hard is that? Stupid monk seals. Maybe they shouldn’t have taken a vow of celibacy. I do have a pack of DNA for these monk seals so I can clone replacements, but that’s just standard DNA hording on my part. Don’t expect me to create any new Caribbean monk seals anytime soon, unless I get the urge for a midnight snack. Mmmmm…. Carribbean Monk Seal BBQ.

After five years of futile efforts to find or confirm sightings of any Caribbean monk seals — even just one — the U.S. government on Friday announced that the species is officially extinct and the only seal to vanish due to human causes.

“Humans left the Caribbean monk seal population unsustainable after overhunting them,” Kyle Baker, a biologist for the National Marine Fisheries Service, said in a statement. “Unfortunately, this led to their demise and labels the species as the only seal to go extinct from human causes.”

Make Way for Superfrog

By Lauren Cahoon
ScienceNOW Daily News
28 May 2008
X-Men fans rejoice: Wolverine has come to life, as a frog. When the comic book warrior faces a fight, metallic blades spring forth from his hand. A new study concludes that certain African frogs are similarly equipped, having sharp, claw-shaped bones that pierce through their own fingertips when the animal is threatened.

More than 100 years ago, scientists observed the mysterious bony appendages in museum specimens of the Arthroleptidae frog family, but they had no idea what to make of them. Some speculated that the protrusions were an artifact of the preservation process. Harvard University biologists David Blackburn decided to solve the mystery once and for all after having the frequent misfortune of being injured by the amphibians while doing field research in Cameroon. “The frogs will start kicking and drag these claws against your skin,” he says. “I’ve gotten bloody scratches from them many a time.”

Due to strict government regulations on removing live animals from Cameroon, Blackburn’s team had to do their anatomical studies on preserved museum specimens. In addition to the talon-shaped finger bones others had seen, the researchers found a small bony nodule nestled in the tissue just beyond the frog’s fingertip. When sheathed, each claw is anchored to the nodule with tough strands of collagen, but, as Blackburn had discovered firsthand, when the frog is grabbed or attacked, the frog breaks the nodule connection and forces its sharpened bones through the skin.

This bizarre skeletal feature is found in only 12 species within the Arthroleptidae family,

New Species Of Peccary — Pig-like Animal — Discovered In Amazon Region

ScienceDaily (Nov. 9, 2007) — Dutch biologist Marc van Roosmalen has discovered a new species of peccary, a member of the pig family, in the basin of the Rio Aripuanã in the south-eastern Amazon region. The divergence time from the already known peccary species (the time which has passed since the evolutionary division) has been set at one to 1.2 million years.

This species has been christened giant peccary (Pecari maximus) by the researchers on account of its size. The holotype of the species can be found in the museum of the Instituto Nacional de Pesquisas da Amazônia (INPA) in Manaus. The giant peccary was known by the local Tupi Indians as Caitetú Mundè, which means ‘great peccary which lives in pairs’.

Peccaries belong to the pig family from the New World (Tayassuidae). Until recently, the species consisted of three types: the collared peccary, the white-lipped peccary and the Chaccoan peccary. In his contacts with local hunters in area of the Rio Aripuanã basin, Van Roosmalen came across three hides of a species of peccary which he had encountered several times in the local jungle, and which differed strongly from the collared peccary which was also indigenous to the area.

The measurements of the body and the skull confirmed that the new species is larger than the other peccary species. The giant peccary has comparatively longer legs and its fur markings are also completely different. The skull sizes of the giant peccary also appear to differ from the other species. Genetic analysis indicates a divergence time with the collared and white-lipped peccary of between one and 1.2 million years. The giant peccary occurs sympatrically with the white-lipped and collared species, in other words they are found in the same region.

The new species also exhibits very different behaviour from its family members, the white-lipped and collared peccaries. These species are found in large to very large groups (even up to hundreds of individual animals in the case of the white-lipped peccary), while the giant peccary is only found in pairs or in small family groups with one or two offspring. The other peccary types root in the ground for seeds and roots.

The giant peccary eats mainly fruit and exhibits little or no rooting behaviour. The habitat of the giant peccary is limited to terra firme, dry wooded areas, in a small region of the basin of the Rio Aripuanã. The researchers therefore expect the giant peccary population to be small, and they recommend that this new species should be placed on the Red List of threatened species of the International Union for Conservation of Nature and Natural Resources (IUCN).

High Degree Of Antibiotic Resistance Found In Wild Arctic Birds

Author: Dr. Mobusu  //  Category: Biology, Dr. Mobusu, Science

It’s not just hospitals that have antibiotic resistant bacteria, now seabirds are getting in on the action! Maybe if seagulls weren’t so damn greedy all the time they wouldn’t be eating all sorts of bad crap. But they do. In addition to eating up things loaded with antibiotics, seabirds are also eating lots of plastic debris, as the ocean is rapidly becoming a swirling mass of plastic particles. I totally have nothing to do with that, and neither does my plastic debris factories operating out of Vietnam and Cambodia! Just keep Captain Planet off my back. And what the Hell kind of power is “love”? How lame can you get?

High Degree Of Antibiotic Resistance Found In Wild Arctic Birds

ScienceDaily (Jan. 15, 2008) — Swedish researchers report that birds captured in the hyperboreal tundra, in connection with the tundra expedition “Beringia 2005,” were carriers of antibiotics-resistant bacteria. These findings indicate that resistance to antibiotics has spread into nature, which is an alarming prospect for future health care.

The scientists took samples from 97 birds in northeastern Siberia, northern Alaska, and northern Greenland. These samples were cultivated directly in special laboratories that the researchers had installed onboard the icebreaker Oden and were further analyzed at the microbiological laboratory at the Central Hospital in Växjö, Sweden.

“We were extremely surprised,” says Björn Olsen, professor of infectious diseases at Uppsala University and at the Laboratory for Zoonosis Research at the University of Kalmar.

“We took samples from birds living far out on the tundra and had no contact with people. This further confirms that resistance to antibiotics has become a global phenomenon and that virtually no region of the earth, with the possible exception of the Antarctic, is unaffected.”

The researchers’ hypothesis is that immigrating birds have passed through regions in Southeast Asia, for example, where there is a great deal of antibiotics pressure and carried with them the resistant bacteria to the tundra.

“We already knew that birds in the Western world can be carriers of bacteria that are resistant to antibiotics, but it’s alarming to find that these bacteria exist among birds out on the tundra,” says Jonas Bonnedahl, a physician infectious specializing in infectious diseases in Kalmar and one of those participating in the expedition.

“Our findings show that resistance to antibiotics is not limited to society and hospitals but is now spreading into the wild. Escalating resistance to antibiotics over the last few years has crystallized into one of the greatest threats to well-functioning health care in the future.”

This research is published in the journal Emerging Infectious Diseases.
