Plants do what Jamie Lynn Spears cannot

Plants have developed the ability to mutually become abstinent. And this is without that terrible government funded program that does nothing but create ignorant children who don’t know how babies are formed. If only Jamie Lynn Spears had a similar gene, the maybe she’d be able to grow up and follow her sister’s footsteps into a downward spiral. Instead, she never even got to take off. I shall use the genes from these plants to create insertions that can be used on child stars to prevent them from raising a new generation of horrible monsters. Saving the world one Spears at a time.

Biologists Find Unusual Plant Gene: Abstinence By Mutual Consent

ScienceDaily (Dec. 26, 2007) — Biologists at the University of California, San Diego have discovered a gene in plants that disrupts fertilization only when mutations in the gene are present in both the female and male reproductive cells. Their discovery has been named the “abstinence by mutual consent” mutation because of its unusual properties.

“Mutations that do not allow fertilization are known in plants, but usually these mutations are caused either by a mutation in the female reproductive cells or by a mutation in the male reproductive cells,” said Julian Schroeder, a professor of biological sciences at UCSD who headed the study. “In this gene, when only the female carries the mutation, completely normal fertilization occurs, and when only the male carries the mutation, fertilization also occurs. But fertilization is completely disrupted when both male and female reproductive cells carry the mutation simultaneously.”

The scientists say the discovery of new genes that control the ability of plants to undergo fertilization could have important applications to plant breeders and conservationists.

“Mutations that cause infertility in crops can provide a powerful tool for breeders who would like to avoid crossing of their plants to related species,” said Aurelien Boisson-Dernier, a postdoctoral scholar in Schroeder’s UCSD laboratory and the first author of the study. “Conversely breeders would at times like to breed crops by crossing them into distantly related species that however do not allow crossing due to infertility. For example, adding beneficial stress resistance genes from another species may not be possible if the male and female reproductive cells can’t communicate properly. Understanding the mechanisms that mediate male-female communication during fertilization could help in circumventing the barrier of such interspecies crosses for breeding new varieties.”

In animals and plants, fertilization relies on complex and specialized mechanisms that allow the precise delivery of the male reproductive sperm cell to the female egg cell. Fertilization requires fusion of the sperm and egg cells. In flowering plants, the male pollen tube carries sperm cells through the maternal tissues to deliver the sperm to the female reproductive cells. Once the pollen tube gets close to the egg cells, fertilization requires the bursting of the pollen tube. This pollen tube bursting expels sperm cells from inside the pollen tube, so sperm can then fertilize the female reproductive cell.

In investigating why the mutation they discovered caused disruption of fertilization in the mustard plant Arabidopsis, the scientists found that the pollen tubes did not burst when they came close to the female egg cells. So in the mutant plants, the sperm cells were not expelled from the pollen tubes toward the female cells. Instead the pollen tubes, in which the sperm reside, kept growing past the eggs cells.

“The abstinence by mutual consent gene is the first gene identified so far with a critical function at the same time in both plant male and female reproductive cells that is essential for the delivery of sperm cells to the egg cell,” said Boisson-Dernier.

“The abstinence by mutual consent mutant pollen just acts as if there were no egg cell around and keeps on growing,” Schroeder added. “It’s interesting because this lack of pollen bursting only happens if the mutation is carried by both the male and female, suggesting the abstinence by mutual consent gene somehow allows the male pollen and the female reproductive cells to talk to one another.”

Boisson-Dernier found that the gene is responsible for producing a protein called peroxin that targets small organelles inside the cell called peroxisomes. Within the cell, peroxisomes are small organelles whose main functions are metabolizing fatty acids, protecting the cell from toxic free radicals and also generating a large range of signaling molecules.

Boisson-Dernier’s discovery demonstrated that peroxisomes play an unexpected key role in the dialogue between the male sperm carrier and the female egg cells. It also implies, the UCSD researchers say, that a diffusible signal generated in the peroxisomes of either the female or male reproductive cells is enough to allow the male-female communication to proceed. This signal coming from the peroxisomes of the male or female is sufficient to set off the eruption of the pollen tube allowing the sperm cells to be released.

“The interesting next question is, what is the signal coming from peroxisomes that causes pollen tube bursting?” said Schroeder.

Boisson-Dernier added, “Why does this signal only cause bursting of the pollen tubes once the pollen tube gets close to the female reproductive cells? These findings actually suggest there may be a second signal or a second key that is needed so the pollen only bursts when male and female are in close vicinity of one another.”

This research is detailed in a paper that appears online December 20 in the journal Current Biology.

Squirrels beginning worship of serpent god Set

Dr. Mobusu here with important news on the front of ancient deities from literary barbarian stories. It would seem that the serpent god Set is not content to be worshipped only by James Earl Jones, but has spread his influence to the local squirrel populations of California. The Golden State is long known to be home of a bunch of fruits and nuts, so a crazed cult growing up there is not news. What is news is that the cult is perpetuated by little furry rodents. Once again, ignorant scientist misinterpret the data thinking the squirrels are masking themselves, not knowing that instead the furry ones are declaring their allegiance to the serpent god. Only when Set’s seven-headed self enters our dimension to devour the living will they know the truth. But I won’t have that happen on my watch, this world belongs to me and no snake god will be eating anyone without my written permission. Suck it, Set!

Squirrels Use Old Snake Skins To Mask Their Scent From Predators

ScienceDaily (Dec. 25, 2007) — California ground squirrels and rock squirrels chew up rattlesnake skin and smear it on their fur to mask their scent from predators, according to a new study by researchers at UC Davis.

Barbara Clucas, a graduate student in animal behavior at UC Davis, observed ground squirrels (Spermophilus beecheyi) and rock squirrels (Spermophilus variegates) applying snake scent to themselves by picking up pieces of shed snakeskin, chewing it and then licking their fur.

Adult female squirrels and juveniles apply snake scent more often than adult males, which are less vulnerable to predation by snakes, Clucas said. The scent probably helps to mask the squirrel’s own scent, especially when the animals are asleep in their burrows at night, or to persuade a snake that another snake is in the burrow.

The squirrels are not limited to the use of shed snake skins, said Donald Owings, a professor of psychology at UC Davis who is Clucas’ adviser and an author on the paper. They also pick up snake odor from soil and other surfaces on which snakes have been resting, and use that to apply scent. Other rodents have been observed using similar behavior.

Snake-scent application is one of a remarkable package of defenses that squirrels use against rattlesnakes, Owings said. In earlier work, Owings’ lab has found that squirrels can: heat up their tails to send a warning signal to rattlesnakes, which can “see” in the infrared; assess how dangerous a particular snake is, based on the sound of its rattle; and display assertive behavior against snakes to deter attacks. In addition, work by Owings’ colleague, psychology professor Richard Coss, has demonstrated that these squirrels have evolved resistance to snake venom.

“It’s a nice example of the opportunism of animals,” Owings said. “They’re turning the tables on the snake.”

The other authors on the paper, which was published Nov. 28 in the journal Animal Behavior, are Matthew Rowe, Sam Houston State University, Texas, and Patricia Arrowood at New Mexico State University. The work was funded by the National Science Foundation and the Animal Behavior Society.

More examples of my growth ray in action! – Giant Cobras!

In addition to the giant rats, I have also succeeded in creating giant cobras because that’s just what I do – make things big or small for no reason. I’m a mad scientist, what do you expect? Naja Ashei is just the beginning!

Record-size spitting cobra found in Kenya

By Nicolo Gnecchi Fri Dec 7, 1:21 PM ET

NAIROBI (Reuters) – A new species of giant spitting cobra, measuring nearly nine feet and possessing enough venom to kill at least 15 people, has been discovered in Kenya, a conservation group said on Friday.

WildlifeDirect said the cobras were the world’s largest and had been identified as unique. The species has been named Naja Ashei after James Ashe, who founded Bio-Ken snake farm on Kenya’s tropical coast where the gigantic serpents are found.

“A new species of giant spitting cobra is exciting and reinforces the obvious — that there have to be many other unreported species but hundreds are being lost as their habitats disappear under the continued mismanagement of our planet,” said the group’s chairman, Kenyan environmentalist Richard Leakey.

Ashe, now deceased, was the first to catch a larger-than-normal spitting cobra in the 1960s and suggest it belonged to a different species.

Bio-Ken director Royjan Taylor said the recognition of the new species was an opportunity to raise awareness about snake conservation as well as find remedies for the powerful bite.

“Naja Ashei is responsible for a very serious snake bite,” he told Reuters by telephone from the farm. “People don’t care about saving snakes. They talk of saving dolphins or cats, but never snakes!”

The conservationists’ excitement has drawn scientific endorsement from a British-based biologist.

Research published by Wolfgang Wuster, of the University of Wales, said a field visit confirmed the Naja Ashei is a new species. “The new species is diagnosable from all other African spitting cobras by the possession of a unique DNA,” he wrote in a review in July.

Giant Rat, Tiny Possum discovered in Indonesia

Greetings, friends, as you can see, my size-altering experiments are proceeding as planned. I have successfully created rats of enormous size as well as begun work on the miniaturizing rays as well. Soon nothing will be it’s original size again, and I will corner the market on custom alterations, thus funding my plans to rule the world!!! MuHAHAHAHAHA!

Giant rat discovered in Indonesia jungle

JAKARTA, Indonesia – Researchers in a remote jungle in Indonesia have discovered a giant rat and a tiny possum that are apparently new to science, underscoring the stunning biodiversity of the Southeast Asian nation, scientists said Monday.

Unearthing new species of mammals in the 21st century is considered very rare. The discoveries by a team of American and Indonesian scientists are being studied further to confirm their status.

The animals were found in the Foja mountains rainforest in eastern Papua province in a June expedition, said U.S.-based Conservation International, which organized the trip along with the Indonesian Institute of Science.

“The giant rat is about five times the size of a typical city rat,” said Kristofer Helgen, a scientist with the Smithsonian Institution in Washington. “With no fear of humans, it apparently came into the camp several times during the trip.”

The possum was described as “one of the worlds smallest marsupials.”

A 2006 expedition to the same stretch of jungle — dubbed by Conservation International as a “Lost World” because until then humans had rarely visited it — unearthed scores of exotic new species of palms, butterflies and palms.

Papua has some of the world’s largest tracts of rainforest, but like elsewhere in Indonesia they are being ravaged by illegal logging. Scientists said last year that the Foja area was not under immediate threat, largely because it was so remote.

“It’s comforting to know that there is a place on Earth so isolated that it remains the absolute realm of wild nature,” said expedition leader Bruce Beehler. “We were pleased to see that this little piece of Eden remains as pristine and enchanting as it was when we first visited.”

Scientists stumble across one of my old weapons

Sometimes I create so many destructive monsters even I can’t keep track of them. Thanks to genetically engineered Sea Scorpions I picked up during a routine trip back in prehistoric time I created monstrous versions that served me well for years, but several were lost during a mission once again in the past. I collected three of the five killed Sea Scorpions, but the two that I couldn’t locate have since then fossilized and been discovered by humans. I will let them take the claim for this one, as it was my carelessness that allowed their discovery in the first place. Never again will I leave a creature behind.

Scientists find fossil of enormous bug

By THOMAS WAGNER, Associated Press Writer Wed Nov 21, 7:54 AM ET

LONDON – This was a bug you couldn’t swat and definitely couldn’t step on. British scientists have stumbled across a fossilized claw, part of an ancient sea scorpion, that is of such large proportion it would make the entire creature the biggest bug ever.

How big? Bigger than you, and at 8 feet long as big as some Smart cars.

The discovery in 390-million-year-old rocks suggests that spiders, insects, crabs and similar creatures were far larger in the past than previously thought, said Simon Braddy, a University of Bristol paleontologist and one of the study’s three authors.

“This is an amazing discovery,” he said Tuesday.

“We have known for some time that the fossil record yields monster millipedes, super-sized scorpions, colossal cockroaches, and jumbo dragonflies. But we never realized until now just how big some of these ancient creepy-crawlies were,” he said.

The research found a type of sea scorpion that was almost half a yard longer than previous estimates and the largest one ever to have evolved.

The study, published online Tuesday in the Royal Society’s journal Biology Letters, means that before this sea scorpion became extinct it was much longer than today’s average man is tall.

Prof. Jeorg W. Schneider, a paleontologist at Freiberg Mining Academy in southeastern Germany, said the study provides valuable new information about “the last of the giant scorpions.”

Schneider, who was not involved in the study, said these scorpions “were dominant for millions of years because they didn’t have natural enemies. Eventually they were wiped out by large fish with jaws and teeth.”

Braddy’s partner paleontologist Markus Poschmann found the claw fossil several years ago in a quarry near Prum, Germany, that probably had once been an ancient estuary or swamp.

“I was loosening pieces of rock with a hammer and chisel when I suddenly realized there was a dark patch of organic matter on a freshly removed slab. After some cleaning I could identify this as a small part of a large claw,” said Poschmann, another author of the study.

“Although I did not know if it was more complete or not, I decided to try and get it out. The pieces had to be cleaned separately, dried, and then glued back together. It was then put into a white plaster jacket to stabilize it,” he said.

Eurypterids, or ancient sea scorpions, are believed to be the extinct aquatic ancestors of today’s scorpions and possibly all arachnids, a class of joint-legged, invertebrate animals, including spiders, scorpions, mites and ticks.

Braddy said the fossil was from a Jaekelopterus Rhenaniae, a kind of scorpion that lived only in Germany for about 10 million years, about 400 million years ago.

He said some geologists believe that gigantic sea scorpions evolved due to higher levels of oxygen in the atmosphere in the past. Others suspect they evolved in an “arms race” alongside their likely prey, fish that had armor on their outer bodies.

Braddy said the sea scorpions also were cannibals that fought and ate one other, so it helped to be as big as they could be.

“The competition between this scorpion and its prey was probably like a nuclear standoff, an effort to have the biggest weapon,” he said. “Hundreds of millions of years ago, these sea scorpions had the upper hand over vertebrates — backboned animals like ourselves.”

That competition ended long ago.

But the next time you swat a fly, or squish a spider at home, Braddy said, try to “think about the insects that lived long ago. You wouldn’t want to swat one of those.”
