My new product is call the needleir, this one of a kind product work as a needle that attached to any book give you all amount of knowledge to your brain in less than a second. People will buy my product since it give less stress and more time to do other things while reading might take hours to consume to your brain and to memorize. i think this is a good product since it can give people vast amount of knowledge in a short time then we would all have straight a student and everyone will have a education in matters of second. Other people may think is unnatural or immoral or against religion view but this is just like inserting a cd to your brain. So instead of taking decades to of school, college ,and etc this would save 2/10th of your live time and you have plenty of childhood left to spare.

Too much sugar turns off gene that controls the effects of sex steroids

2008-05-20T11:38:00.000-07:00

The sugar level can change a person gene level and might even turn off the gene.the average american consume 33kq of sugar and 20kq of high frutose corn syrup. high production of lipid which get to their by high amounts of suger which shut down a gene called SHBG (sex hormone binding globulin).Dr. Geoffrey Hammond say that low levels of SHBG in a person’s blood means the liver’s metabolic state is out of wack nappropriate diet or something that’s inherently wrong with the liver long before there are any disease symptoms. theses are my links http://www.biologynews.net/archives/2007/11/10/too_much_sugar_turns_off_gene_that_controls_the_effects_of_sex_steroids.html

Biological Entrepreneurs

2008-04-23T13:08:00.000-07:00

Whenever a child is sick, parents instinctively search out medicine or a cure. The task has been an unusually daunting . Two children were diagnosed with a rare muscle-wasting disorder called Pompe disease. The affliction is so rare, that not only was there no medicine to treat it, but the big pharmaceutical companies weren't even thinking about developing drugs for it.

So John Crowley did the only thing he could. He rounded up some scientists, hit up venture capitalists, and started a company to develop a drug to save his children's lives. It's been a draining five year odyssey, but earlier this year the Crowley children started their treatmentcthe former Soviet physician, microbiologist and biological warfare (BW) expert who play a major role in founding of Biological Entrepreneurs on march 11. His early job has to do with alot of thing related to biology which are Soviet physician, microbiologist and biological warfare (BW) expert. His main job was bio-defence for america in 1992 he retired to becoming a american citizen. He is Chief Executive Officer of AFG Biosolutions Inc and President and Chief Executive Officer of MaxWell Biocorporation, LLC right now. he wish to make factorys of

Alibekov wasn’t at Biomash long when he was placed in charge of the intensive preparations for the facility inspections that were to be conducted by a joint American and British delegation. While participating in the subsequent Soviet inspection of American facilities, his growing suspicion that the United States did not have an offensive BW program was confirmed before his return to Russia (the Soviet Union dissolved while he was in the US). Not long after his return from the US, Alibekov resigned from both the Soviet Army and from Biopreparat and secretly emigrated with his family to the US in the fall of 1992.^[5]

Since moving to the US, Alibekov — who simplified his name to Ken Alibek — has provided the government with a detailed accounting of the former Soviet BW program and has testified before the U.S. Congress on numerous occasions (see also Sverdlovsk anthrax leak). He has provided guidance to the intelligence, policy, national security, and medical communities and has returned to the pure biomedical research that captured his interest as a medical student. He was the impetus behind the creation of an innovative biodefense graduate education program at George Mason University (GMU) that drew students from across the country and has served in the program as both a Distinguished Professor of Medical Microbiology and as the Director of Education. He also developed the plans for GMU’s biosafety level three (BSL-3) research facility and was instrumental in obtaining $40 million dollars of grants from the federal and state governments for construction of the facility.^[6]

In 1999, Alibek published an autobiographical account of his work in the Soviet Union and his defection. instrumental in obtaining $40 million dollars of grants from the federal and state governments for construction of the facilityMaxwell Biocorporation, LLC is considered the biggest and most modern pharmaceutical production facility in all of the former Soviet Union.

the eye dissection

2008-04-21T09:58:00.000-07:00

Today we did a eye dissection we use real sheep eyes. we got a guest interview today. With way chan she told us that the eye was a very complex tissue that should be handled with care. we learn that she the mother of Alice chan. she taught us the important of keeping our eye healthy and clean so that we wont infect our eyes. also if we have dust and resource contaminated and cost blurrewd vision and redness in the eye balls. we learn alot of the parts of the eye balls what in and outside of the eyeball theses are picture of the eyeballs we dissect.

Mutated Zebra Fish

2008-03-05T13:18:00.000-08:00

Scientists are now able to produce zebra fish who deserve the bizarre names given to them: half-baked, avalanche, speed bump, zombie, ogre, lost-a-fin, piggy tail, snow white, bashful, sleepy, cyclops, mind bomb, uncle freddy, dogeared, van gogh, silentheart, and throbless. Not your typical names for fish often sold to people setting up their first aquariums. However, with a little gene mutation, most of these names are quite appropriate (we may never know for sure about uncle freddy, though. Small groups of scientists around the world have been working to generate embryos of zebra fish whose development was lethally interrupted by a single gene mutation.

The simplified process of achieving these embryos begins with taking a male zebra fish and dunking it in the chemical mutagen ethylnitrosourea. These fish are then bred to create mutated embryos. These mutations effected the embryos in a myriad of ways, such as miswired nervous systems, pigmentation defects, eye abnormalities, and tail malformations, and undeveloped muscles. Several mutations disrupted epiboly, the very first cellular movement of the embryo. The zebra fish embryo depends on a yolk-laden cell until they can feed themselves. During normal epiboly, the cells spread over the yolk. The research ultimately identified mutations in about 600 specific genes.

Many varieties of heart mutations were discovered. These mutants have established thathearts are assembled by sets of genes that are responsible for discreet parts of the organ. It is hoped that by researching the mutants, the scientists will be able to understand why congenital heart disease occurs in humans. Zebra fish with improper blood formation have also been developed. One mutated zebra fish named dracula died when it was exposed to light. The red blood cells became fluorescent and popped. It was originally though that this mutant developed no blood, but it was later discovered that if the fish was raised in he dark, it would have blood. However, an enzyme deficiency makes the blood pigment sensitive to light. There are related enzyme deficiencies, called porphyrias, that cause human diseases.

It is the hope of these scientists that by studying the mutated genes of these fish they will be able to identify and clone all of the genes used by a developing vertebrate embryo. In the past year, they have made many advances. They observed that the shield tissue of the zebra fish embryo signaled the animal cap to start developing into part of the nervous system. For the first time, a cell had been identified in the embryo that could induce neural tissue. By identifying the genes responsible for disturbed nervous systems in the mutants, the scientists hope to discover the exact nature of the signals.

Scientists have almost entirely mapped out the genetic structures of the zebra fish by studying the mutants. This knowledge allows them to hone in on the genes of the fish much faster. The faster the genes can be identified, the faster they can be cloned. The ultimate purpose of the zebra fish mutations is to clone vertebrates. Even though this has already been accomplished with Dolly, the infamous sheep, research has not stopped. Besides cloning live animals, scientists could replace mutated genes in humans that are causing diseases if they can effectively clone "healthy" genes. While the prospect of human cloning and its ramifications frightens many, gene cloning has other uses. Many now incurable diseases could be brought under control with the development of this new technology. It can take a lone researcher up to a year to clone a single gene, but new techniques are allowing this branch of science to develop much more rapidly. A group of scientists in Massachusetts hopes to be able to clone all the genes to make a vertebrate by 1999. It's amazing what science and a zebra fish names dracula can accomplish.

Elephantidae

2008-02-25T09:54:00.000-08:00

Elephants are Kingdom: Animalia, Phylum: Chordata,Subphylum: Vertebrata,Class: Mammalia,Order: Proboscidea, Superfamily: Elephantoidea, and family is Elephantidae.

Elephants originally live in Asia and Africa, Asian elephants are the only surviving asian elephant genus. African elephants, at up to 4 m (13 ft 1 in) tall and weighing 7500 kg compare top Asian elephants they are little bigger in ears and size.

Predator of elephants are only African tigers since they live near African elephants beside that the number 1 threat to their survivor is African hunter and people since they killed them for their valuable tusk.

A national park was made to perserve the elephants it was called the Kruger National Park in South Africa.during 1960s the Kruger National Park slaughtered 14,562 elephants in the reserve between 1967 and 1994; it stopped in 1995, mostly due to international and local pressure. Officials at the Kruger National Park say that without action, the elephant population there will likely triple to 34,000 by 2020.

elephants have affected many of our culture and life, if you ever see the movie jumbo which was a a Disney classic for children everywhere about a elephant. Some elephants are used in war and battle in the past which was feared in most lands since war elephant are the biggest threat back then.

Beside all that elephants are smart and intellectual creature they can feel pain,love, and etc emotion as human so to me we shouldn't kill them or put them in cage since they can feel like our pets dog and cats. So i hope you enjoy my blogger of elephants.

LOUISE MEAD

During january 24,2008

A guest speaker Luise Mead of the national center of science education came and talk about evolution and that the theory for evolution is a fact and not just a theory. she told us that not many public school beside mills high accually encourage the teaching of evolution since alot of poeple are religous and belive evolution is just a theory. Thus accepting fact of evolution mean religon doesnt exist since religion has no evidence of it own. She gaves us fossil of evolution which is evidence to theory of evolution. she talk about salamanders and how they have a distinct way of mating.

when i heard her speak i got an elightenment which open my eyes to science instead of religion ,which the line of fact and fiction collide. she taught me more of how i understand the world and how it evolve over time which make sence of mostly everything of what religion is lacking. since mostly i question myself why this why that could go on forever but now evolution gave me a valouble answer to one of my biggest question ever where we came from.

Lack of antioxidants may take the spring in your step away

2007-12-12T21:08:00.000-08:00

I found out that why i always sleepy even i sleep early sometime i just few very tired and just wanted to sleep. this make me take more stuff with antioxidants with it. even fish that have less antioxidant there muscle are thiner and weak. Not only human any living thing need antioxidant which is important for my body. Now i know that without antioxidant i can be sleepy and not concentrated on my work which is bad for my grade so now i need to sleep early and eat breakfast which is a important meal for my body and has antioxidant.

These are the website i took the information off of http://www.ebiologynews.com/3773.html

Theses are the some of the picture of antioxidant and food that contains it.

Rosemary Chicken Protects Your Brain From Free Radicals

2007-11-02T08:46:00.000-07:00

Im diong a report on how rosemary can be good for your brain. Rosemary protect your

brain from radical that can damage your brain. There a ingrediant in rosemary known as

carnosic acid that prevent you having stroke and neurodegeneration. also it can prevent you

from some bad effect on your normal aging brain which is bad. Rosemary came from a shrubby

evergreen bush and according to folklore it takesthe name from the Virgin Mary . Who draped

her cloak on the bush placing a white flower on top of the cloak which By the following morning,

the flower had turned blue and thereafter the plant was known as the “Rose of Mary.”

Rosemary are found in the Alps during the Middle Ages, has became part of European folk

medicine, and was thought to help the nervous system and ward off sickness. Until now exact

chemical pathways involved in its helpful effects have remained unknown to us till now. So i

hope you like reading what i wrote for this biology news.

i found this article from this website http://www.sciencedaily.com/releases/2007/10/071030102210.htm

2007-10-19T18:11:00.000-07:00

today in biology i learn that snial are creature of instinct. when we put vinager on it, it got hurt which tell us it has a nerve organ and can feel pain like us. we tested it with different thing like what it will do and how it will get across the tiny class. we also learn that they are intellegent sincewhen they see food they go reach for it and when they sence danger they hide in there shell. the shell protect them since they are very weak in the inside which they have no cytoskeleton. they reproduce asexually since they have no female or male. that i learn today in the snial reserch lab. i enjoy it very much!

Predation Linked To Evolution, Study Suggests

2007-09-13T23:36:00.000-07:00

Science Daily — The fossil record seems to indicate that the diversity of marine creatures increased and decreased over hundreds of millions of years in step with predator-prey encounters, Virginia Tech geoscientists report in the Proceedings of the National Academy of Science.

For decades, there has been a debate between paleontologists, biologists, and ecologists on the role of ecological interactions, such as predation, in the long term patterns of animal evolution.
John Warren Huntley, a postdoctoral scientist in the Department of Geosciences at Virginia Tech, and Geosciences Professor Micha³ Kowalewski decided to look at the importance of ecology by surveying the literature for incidents of predation in marine invertebrates, such as clams and their relatives.
"Today, certain predators leave easy to identify marks on the shells of their prey, such as clean, round holes," said Huntley. "Such holes drilled by predators can also be found in fossil shells."
The researchers also looked for repair scars on the shells of creatures that survived an attack.
The study was conducted by looking at studies which reported the frequency of drill holes and repair scars in fossil species from the last 550 million years.
First Huntley and Kowalewski found that predation increased notably about 480 million years ago, some 50 million years earlier than previous studies have found. "The earlier studies were based on changes in morphology -- predators with stronger claws and jaws and prey with more ornamented shells. We looked at the frequency of attacks, which increased about 50 million years before the changes in armor," said Huntley.
But the most notable discovery is the observation that the incidence of drill holes and repair scars are strikingly parallel to Sepkoski's diversity curve for marine invertebrates. This diversity curve, compiled by the late Jack Sepkoski of the University of Chicago, records the origination and extinction of marine animal genera through the last 540 million years (Phanerozoic). "There is a strong correlation between predation intensity and global marine biodiversity in the Phanerozoic," Huntley said.
In their article, "Strong Coupling of Predation Intensity and Diversity in the Phanerozoic Fossil Record," the researchers offer three rival hypotheses to explain the correlation. "It's the classic problem with interpreting a correlation," said Huntley "you have to be careful when ascribing a cause. Let's say factors X and Y are correlated. A change in X could cause a change in Y, a change in Y could cause a change in X, or X and Y could both be controlled by another factor."
The first hypothesis is that predation intensity could be driving diversity. "In this case, ecological interactions would matter in evolution," said Huntley. "Organisms evolve over the long term in response to their enemies, and with increased predation intensity more species evolve."
The second hypothesis is that as biodiversity increased, by chance predators with more complex feeding strategies evolved. "Predatory techniques like drilling and peeling shells are more evolutionarily-derived than more primitive forms of predation like whole ingestion. In this scenario you would expect to evolve sophisticated forms of predation only when diversity is high," said Huntley.
And the third hypothesis is that something else is driving both predation and biodiversity. "Some periods have more sedimentary rocks, and therefore more fossils, preserved than others," said Huntley. "There is less diversity to be observed when there are fewer fossils to study. Perhaps this sampling bias affects our ability to find samples with high predation intensities as well."
"Now we will try to pick this apart," said Huntley. "We can test these hypotheses by examining relevant linkages between predation intensity and diversity in modern oceanic environments. Also, understanding the true nature of Sepkoski's curve will help us interpret our findings. Is it biological? Is it the product of uneven sampling?"

Fire Ants Killing Baby Song Birds At High Rates

2007-09-12T17:30:00.000-07:00

Science Daily — Red imported fire ants may be killing as many as a fifth of baby song birds before they leave the nest, according to research recently completed at Texas A&M University.

Andy Campomizzi, graduate research assistant in the department of wildlife and fisheries sciences, studied black-capped vireos and white-eyed vireos in Coryell County over a span of two years Campomizzi kept records on a total of 72 nests of both species. Of the nests where there was no pesticide treatment, only 10 percent of the young birds fledged and were able to leave the nests. Of the nests with treatment to protect them from fire ants, 32 percent fledged. Nearly 70 percent are lost to other causes, and fire ants knocked the survival rate down an additional 22 percent.
"That was a bigger difference than we thought it would be," he said. "Fire ants were definitely a mortality factor for song birds."
The black-capped vireo – which breeds only in the Edwards Plateau of Texas, a couple of areas in Oklahoma and northern Mexico – is an endangered species. The white-eyed vireo is found more extensively throughout the southeastern U.S. and is not endangered.
In his research, Campomizzi would find nests with eggs and attach Arinix – a nylon plastic cable wrap developed for use in protecting electrical equipment from fire ants – around branches. Some of the wraps were permeated with permethrin insecticide and some not.
A sticky insect trap coating was applied to the branch on the limbs with the insecticide, so the ants could not get around the trap to the nest, he explained. Nests were isolated so access was limited to one or two routes for the fire ants, he said.
He checked the nests every three or four days. He counted the nest as a success if the adults could raise at least one of their young until it could fly out of the nest, which takes about 10 to 12 days from hatching.
Campomizzi believes fire ant predation may occur among any song bird species, although mortality rates would vary depending upon local populations of the red imported fire ant and how close to the ground the birds were nesting.
Management for black-capped vireos is ongoing on both public and private land, he said.
"Current management includes providing breeding habitat and removing brownheaded cowbirds, a brood parasite," Campomizzi said.
Land managers interested in improving black-capped vireo habitat may want to consider managing fire ants around nesting areas to increase the chances that they can successfully raise their young. This will perhaps contribute to the species' recovery from being endangered, he said..
The research was funded by the Texas A&M Institute of Renewable Natural Resources.
