American Athiest Fever continues

Late last night/early this morning I blogged about the New York atheists put an ad on 20 NYC buses claiming that "You don't need to believe in God to be a moral or ethical person."
While the ad has no doubt ruffled a few feathers, I doubt it received the amount of negative attention that its Florida counterpart, a billboard reading "Being a good person doesn't require God. Don't believe in God? You're not alone."
The billboard, posted by Free Thought Flordia, has received numerous complains and protests by those who claim the billboard is offensive to Christianity.

I will admit that this sign seems slightly more blunt then the NYC ads. However, I don't see how it can be offensive. It clearly falls within their freedom of speech. It doesn't bash or target any particular religion. I suspect the majority of the complaints are from the same evangelicals who hate gays and Planned Parenthood.

Glowing Salamaders

Today Nature magazine is publishing an article led by developmental biologist Elly Tanaka, (from the Center for Regenerative Therapies at the Dresden University of Technology), explaining the mechanics of salamander limb regeneration. Elly Tanaka genetically engineered an axolotl salamander with a green fluorescent protein in all cells of the body, which allowed her to visually trace the fate of cells during regeneration. Her discovery was quite startling and already the science blogging community is buzz with excitement.

Scientists have long observed the salamander's unique ability to regenerate not only limbs, but jaws, skin, and even parts of brain and spinal chord. Scientists originally theorized that regeneration occurs because cells at the amputation site lose their identities and turn back their developmental clocks and become "pluripotent" stem cells (capable of developing into many cell types in the body), which then recreate the lost limb.

This study explains that cells at the amputation site retain memories of their identities and regenerate to form the same type of tissue in the replacement limb. The concept of cellular memory is still wearily approached by scientists and researchers, but in the case of the salamander, it's what makes regeneration possible. It also means that instead of stem cells, the amputated cells simply reproduce more of themselves; muscles grow from muscles, and bones from bones.

Lets All Jump on the Atheist Bus!














New York City Atheists, Inc. placed a pro-atheist ad on 20 New York city buses which reads "You don't have to believe in God to be a moral or ethical person."

While I am sure it has stirred up its share of complaints, I like this ad campaign better than last year's atheist ad campaign in England, which stated "There's probably no God. Now stop worrying and enjoy your life." While London's atheist ad was amusing, it did stir controversy. The New York counterpart is far less contriversial; it doesn't focus on whether or not there is a god. It simply states that you don't need religion to be ethical. No one can deny that this fits within their rights of free speech, and gives encouragement to NYC atheists without (hopefully) drawing too much criticism.

Even Joseph Zwilling, the director of communications for the Archdiocese of New York, claims that the ads are not offensive to the Catholic Church, because of their careful wording.

So...

...have you done anything about global warming yet?














No?
*sigh*

Karyomapping















If you happen to be a woman with £1,500 - £2,500 laying around and considering in-vitro fertilization, then you may check out this nifty new test. It's an embryonic genetic test called "Karyomapping," and it tests for over 15,000 genetic conditions, including Huntington's, cystic fibrosis, and some types of autism, metal retardation, and cancer. This method is also quicker than existing methods of genetic testing.
And that's not all folks! It also counts the number of chromosomes in embryos, which will help increase chances of impregnation, as well as cutting chances of miscarriage.

Being a Medical Technologist major, and a incurable lab geek, I have to admit that the news of this test excited me. I hope to see this test in the States soon ^_^

However, the tests is not without it's opponents. Some decry the test, saying the helpless embryos will be destroyed because they are not perfect enough, will encourage designer babies, or "savior babies," which are children genetically designed to be a match to a sick sibling. Jodi Picoult wrote a beautiful work of fiction about a girl who was designed to be a genetic match to her sick older sister. (This book, "My Sister's Keeper," is now a movie starring Cameron Diez). While ethics should not be ignored, I hope scientists will push for this test to become mainstream, giving hope to mothers choosing in-vitro.

If all goes well, we can expect to see this test by 2010.

Medical News

I went for a hike to explore some ruins of an old mine today, and need a break from processing pictures. So here's what has been going on in the medical world lately.

- We all know its good to eat your veggies. But more and more we're finding out that it not only matters what you eat, but also how you eat it. For example, it's healthier to eat whole fruit instead of their dried counterparts, which we consume more of in a single sitting, which causes us to intake more sugar. Or, as a Newcastle University study finds, cooking carrots whole seems to boost their antioxidant properties. I can hear the vegans rejoice!
Experience the deliciousness @ http://www.telegraph.co.uk/scienceandtechnology/science/sciencenews/5550278/Anti-cancer-properties-of-carrots-boosted-by-cooking-whole.html

- Now, while some researchers are skeptic of the full effectiveness of antioxidants, people in general are looking more and more to antioxidant foods to boost their health. Well good news gentlemen, eating all those blueberries and cooked carrots is boosting your sperm quality and your manliness! (What woman can resist a guy seductively munching a carrot?) According to a study published in Fertility and Sterility, men who eat antioxidant rich foods have a high sperm quality than men who have a meat-heavy diet.It should be noted that this study was done mostly by survey, but it does show potential and I hope to see it studied more in the future.
Check out the details @ http://www.livescience.com/health/090605-sos-antioxidants.html

- Anyone who has experienced insomnia (like me) knows the toll it can take on everyday life. Doctors have preached the importance sleep for decades, and new studies occur every year which support their advice. The most recent of these studies is one lead by Susumu Tonegawa, the Picower Professor of Biology and Neuroscience at MIT. The study displays a link between long term memory and sleep, specifically memory replay and memory consolidation. Translation: sleep helps us transform our recent, short-term memories into long term memories.

- Mycobacterium tuberculosis is a nasty little critter, and tuberculosis was once a fairly common ailment. Even today it poses great risks among impoverished nations, and even among the homeless here in America. Researchers of Ohio State University are using the power of math to help fight the air-born disease, hoping a change in the natural switching time with result in a better immune response. It studies the complex relationship between the Mycobacterium, the human lungs, and immune system, and I'm not gonna lie, the article is pretty long and intense. But it's a great and thorough article, and hopefully will greatly impact the future of how we deal with TB and other airborne pathogens.

- Your brain is a remarkable organ, and one you want to take care of. Come on, who doesn't sing lullabies to their sweet little neurons when no one is looking, or occasionally spoil them with crossword puzzles?
Glioblastoma multiforme is a nasty brain tumor, which accounts for 52% of all primary brain tumor cases, as well as 20% of intracranial tumors. It is both the most common and most aggressive brain tumor; Definitely not something you want hanging around your innocent neurons. Good news, however: scientists have identified a specific biomarker which is effective (in animal trials) in gauging the response to a new gene therapy treatment for glioblastoma multiforme. The biomarker is a protein released by dying tumor cells, and it's effectiveness in animal trials means it will soon go into Phase 1 clinical trial, hopefully later this year.

- Any way you cut it, it's still surgery. So when it comes to abdominal surgery, transverse and midline incisions shouldn't be that different. Or are they? While most abdominal surgery today is done with minimally invasive techniques ("keyhole surgery"), larger abdominal surgeries still require good old-fashioned incisions. So to satisfy the curiosity of doctors, Heidelberg University Hospital's surgery department conducted a study on the healing quality of both midline and transverse incisions. The results: wound infections were slightly higher in transverse incisions. Other then that, healing time, quality, and complecations were consistant and seemed to be unrelated to incision type.

New Hope for HIV Vaccine



















Lets face it. Canada is awesome.
Microbiology professor Yong Kang, from University of Western Ontario in London, has been working on an HIV vaccine for 20 years, and announced that the vaccine is ready for human trials in the U.S. It has successfully passed animal safety trials, and once they get FDA approval, they will perform 3 human clinical trials. If all 3 trials are successful, then we have a new vaccine.
Isn't it amazing how far we've come?
I hope that this vaccine works, it will completely change the medical world.
Over 33 million people have HIV, and half of those usually develop into AIDS. HIV complications kill 2 million people a year.

Straight From the Heart

Those geniuses from the Harvard Stem Cell Institute identified the earliest master human heart stem cell from human embryonic stem cells. This is particularly helpful in how congenital heart disease develops. Congenital heart disease is the most common heart defect in children all across the globe, and this new discovery will hopefully lead to new treatments and possibly a cure.

Quick, what does FMD stand for? Fetal Muscular Disorder? Fatal Medicine Diagnosis? Funny Monkey Day?
FMD is short for fibromuscular dysplasia. Ever hear of it? Probably not. Most people, even many doctors, are unfamiliar with the disease. Fibromuscular dysplasia is a disease where the artery walls expand, often cutting off blood flow and resulting in cardiac arrest, which is what happend to 10 year old Haley McWhorter. Doctors believe that FMD is a very rare disease, but new studies suggest that the disease is more common then once believed, possibly 3% to 5% of the population (about 10 million Americans.) Symptoms include "young patients with high blood pressure, or who have had a stroke or temporary symptoms of a stroke; patients whose blood makes a swishing sound indicating turbulent flow; or patients with brain aneurysms."

Technology
- Looking for an emissions-free mode of public transportation? We may one day have it. Geoffrey Barnett, a designer, came up with a monorail system powered by an abundant energy source: people! (Why didn't we think of that?) He incorporated his concept, "Shweeb," in a New Zealand amusement park, where people can ride his monorail, which moves via pedaling, which also makes for a great work out. Emission-free transportation and a cure for obesity? Goeffrey Barnett is a genius! I hope that we soon see this monorail our own cities ^_^

Biology
Sea Lamphrys are bizzare-looking fish which seem to be a distant relatice of the Arrakis sand worms (if you're a sci-fi nerd/Frank Herbert fan). The remaining three species of Lamphrys are also rare fish, due to the fact they need high water quality to live. So imagine biologists delight when they found 7 of the little buggers in a river in County Durham, Britian.

Light Up Your Life

I love technology.

A company called Electro-LuminX has come out with a product called Light Tape, a thin, flexible, all-weather lighting strip which they claim is visible for miles, even through rain, fog, and snow.
Light Tape uses a process known as Electroluminescence, which converts electrical energy into light by activating a phosphor layer with an alternating current, which excites the phosphors, causing them to vibrate, thus producing light. Even the Air Force uses electroluminescence for their planes. Cool, no?



You can check out further information on Light Tape, and even buy it @ www.lighttape.com

Is the Swine Flu Drug Resistant?

When the Conflicker virus was due to strike thousands of computers, my computer geek friends were excited, waiting to see what would happen. My economy/business major friends are still excited over the state of the economy and spend hours theorizing how it will play out.
Me, being the medical sciences nerd, found my excitement in the swine flu. Sure, it's not as deadly or dangerous as SARS, or as annoying and painful as Lyme Disease, but the arrival of any new virus or disease excites my inner medical geek.

The latest development in the swine flu frenzy comes from Denmark, where doctors report that the flu is now showing resistance to the antiviral medication Tamiflu (oseltamivir). To date, the virus has only displayed resistance in one patient.

Actually, this really isn't unexpected. Drug resistant strains of various flus have occured before. The real exciting part is whether this is a one time thing confined to a few, isolated cases, or if it will develop into a new, drug resistant strain.
