I got this one for all the ladies that come over to my house for tutoring and are in a emotional panic over their chemistry class. (Have you noticed the camera on my smart phone is scratched? I got my hubby's cast-off with the jacked up lens. At least it is a phone, and it's smart.)

From girls, to teenagers to grown women, I have seen more tears shed over chemistry than any other subject. And if there is one thing that will guarantee failure in chemistry is panic; the outward sign of that panic is tears. So if you want my help, the tears have to cease. Otherwise, learning cannot continue. Tears = total brain shut down.
It is not that women are bad at chemistry. I actually find that females are better at the details required than their male counterparts. They just have to believe that they can do it.
I have written about this gender difference in detail at Creative Minority Report. Here is an excerpt:
Faced with a difficult multi-step problem, males and females attempt to solve said problem with divergent styles. A male will skim the problem and immediately start furiously writing, almost as if it is a race. He then circles his answer and looks at me with a proud look on his face. At this point, I burst his bubble and tell him his answer is wrong. It is wrong because he did not read the question carefully and so instead has the right answer for a different question entirely. (I believe this mental process is the same one that causes men to be reluctant to read directions or consult a map.)
A female will read the question carefully, consider it, and consider it. She knows exactly what the question is asking. She can usually see the first step in her head, but after that she does not know where to go next. Since she cannot easily see the destination, she begins to panic. Her lip starts to quiver and her eyes begin to tear up. The problem never gets solved and all she has for her trouble is a blank piece of paper with a tear-stain on it. (I have experienced this phenomenon more times than I would like to admit so I immediately spot it in those women I work with.)
If I can get her to take just one step in the problem, she is usually more likely to get the question right than her male counterpart who didn't bother to read the question properly. That first step, even if it is in the wrong direction, illuminates the next step, and then the next and finally the girl gets to the destination: the right answer. But she has to get over her emotional response to a difficult question and take that first step.

This is one of the strangest treatment plans I have ever read about. Doctors in New York will purposefully give young adults with autism parasitic worms in hopes of treating their autism. Yes, you read that right. Worms.
The thought is that the non-harmful parasitic worms will engage immune system which doctors hope will reduce the inflammation characteristic in patients with autism. The Scientist has the slimy, squirmy details:
A growing body of evidence suggests that in some patients, increased inflammation contributes to autistic behaviors. Now, a Phase I clinical trial is under way to measure the effects of infecting autistic patients with a non-pathogenic parasitic worm. Scientists at Montefiore Medical Center at the Albert Einstein College of Medicine in New York and biotech company Coronado Biosciences will test the hypothesis that treating these patients with Trichuris suis, a non-pathogenic parasitic pig whipworm, will dampen their immune responses and ameliorate repetitive and irritable behaviors.
“The trial is a novel approach [to autism treatment] with a naturally occurring drug delivery system”—a parasitic worm, said Eric Hollander, a Montefiore psychiatrist and head scientist on the trial.
Autoimmune and allergic diseases are more prevalent in more developed countries where citizens are accustomed to better water quality and less contact with farm animals. Some researchers chalk this phenomenon up to the so-called hygiene hypothesis, which posits that the microbes and parasites that humans co-evolved with act to help keep our immune responses in check. The theory was spurred initially by observations in humans—that after anti-parasitic therapy, people scored higher on allergy skin prick tests, or that autoimmunity and allergies were more prevalent in more-developed West Germany than East Germany—and supported by laboratory studies on mouse models of such diseases, said Marie-Helen Jouvin, a pathologist at Beth Israel Deaconess Medical Center and Harvard University, who is not involved in the clinical trial. Parasites, such as the whipworm used in the autism trial, are thought to both dampen inflammation and stimulate immune regulatory pathways in their hosts.
Cool, but seriously gross. I am not sure I could get over the "infected with parasitic worms" part. The trial will be for 10 adults aged 18-35. Here is hoping this trial has some positive results. Otherwise it might just be opening a can of worms. Sorry....I couldn't resist.

I don't know how many times I have heard it. Well-meaning Catholics who say, "As a Catholic, I believe life begins at conception." I have decided that my mission in life is to correct this miscommunication because it is that very line that lets everyone who is not Catholic dismiss everything we have to say about stem cell research, cloning and reproductive technologies.
We Catholics do not "believe" life begins at conception, also called fertilization. We instead know that it does because it is a cold hard fact of nature that a new, distinct, human organism, identifiable by his or her unique DNA, is created at the completion of fertilization. That is not a belief. That is a fact. Continue reading at Creative Minority>>

Today's geeky t-shirt blogging is in honor of the new James Bond movie Skyfall.

I love all my t-shirts but I this one because of its "sophistication." In chemistry, there a laundry list of different interactions between atoms and molecules. Two of the most commonly known are ionic bonds and covalent bonds. (You should have learned about these in your high school chemistry class.)
When an atom of metal and an atom of a non-metal meet, the metal happily hands over an electron or two (or three or four) to the non-metal which greedily takes them. This causes the metal atom to become a positively-charged ion and the non-metal to become a negatively-charged ion. The metal and non-metal are then attracted to each other because of their opposite charges. This attraction is called an ionic bond.
A covalent bond happens when two non-metal atoms meet. Both want each other's electrons, so like toddlers fighting over a toy, the only way both non-metals can be happy is if they share electrons. This sharing of electrons between atoms is called a covalent bond.
So an ionic bond is one where electrons are taken and a covalent bond is one where electrons are shared.
Hence the "Taken. Not Shared." Funny right?!?!?

If you still doubt that in vitro fertilization (IVF) has commodified children and turned human procreation into human manufacturing to specifications, then read this LA Times story about a fertility doctor that is creating embryos in bulk, from one sperm donor and one egg donor, so that couples can get "discount" embryos:
In the cutthroat field of fertility treatments, Dr. Ernest Zeringue sharply cuts costs by creating a single batch of embryos, then divvying it up among several patients. One 'horrified' critic calls it the 'commodification of children.'
Dr. Ernest Zeringue was looking for a niche in the cutthroat industry of fertility treatments.
He seized on price, a huge obstacle for many patients, and in late 2010 began advertising a deal at his Davis, Calif., clinic unheard of anywhere else: Pregnancy for $9,800 or your money back....
Zeringue sharply cuts costs by creating a single batch of embryos from one egg donor and one sperm donor, then divvying it up among several patients. The clinic, not the customer, controls the embryos, typically making babies for three or four patients while paying just once for the donors and the laboratory work.
People buying this option from Zeringue must accept concessions: They have no genetic connection to their children, and those children will probably have full biological siblings born to other parents.
Inside the industry, Zeringue's strategy for making embryos on the cheap has spurred debate about the ethical boundaries of creating life.
"I am horrified by the thought of this," said Andrew Vorzimer, a Los Angeles fertility lawyer alarmed that a company — not would-be parents — controls embryos. "It is nothing short of the commodification of children."
...Before the clinic makes a batch of embryos, it sends an extensive profile of a sperm donor and an egg donor to prospective parents.
Once the clinic gets buy-in from a few patients, it purchases the sperm from a sperm bank, harvests eggs from the egg donor and combines them in the laboratory.
A single pairing can result in a dozen embryos, and the clinic keeps the extras frozen while it looks for patients who want them.
"We want to keep the embryos moving," Zeringue said. "The goal is not to create a bank."
So Zeringue's clinic is the Costco of the fertility industry. Cheap prices on lots of inventory with no choice as to what he carries. Nice. You know it's bad when a fertility lawyer is horrified.

Dogs are well known for their keen sense of smell. It turns out their noses are good for more than just detecting scent. Scientists in England have isolated cells from the noses of dogs with spinal cord injury and have used those cells to reverse the canines' paralysis. Continue reading at LifeNews >>

There is a dangerous philosophy emerging in our fast-paced, technology-driven world of which most people are totally unaware. And yet, when Francis Fukuyama, economist at the Johns Hopkins School of Advanced International Studies, was asked what idea posed the "greatest threat to the welfare of humanity," his answer was this philosophy.
And yet I am positive most Catholics have never heard of it. Catholics certainly do not realize that they are being fed a steady diet of images in popular media that play right to the more seductive aspects of this ideology. Continue reading at the National Catholic Register >>

So being the true geek that I am, I have a collection of geeky chemistry t-shirts. I heart chemistry so much that I have quite a few chemistry related shirts and an even longer wish list of ones I want to possess. I thought as a light-hearted post on Fridays, I would share them with you. Here is the one most people like the best. I like to wear it to the gym:
But true to the chemistry teacher in me, I cannot simply leave you with that little chuckle. I have to explain why this is so funny. In the atom, there are protons, neutrons and electrons. Relatively, protons and neutrons are big. Electrons are very, very, very small. Practically negligible. So really it is the protons and neutrons that give an atom most of its mass. So adding a proton would significantly increase the mass of an atom. (Technically, adding a proton would turn it into another element entirely, but I digress.)
So the answer is, "Yes! That proton DOES make your mass look big!"
(Have I mentioned how embarrassed my children are of me?)

Scientists from the University of Washington have been able to remove the extra chromosome 21 in cells taken from a person with Down Syndrome. In a gene therapy process that targets only the extra genetic material in the cell, scientist were able to successfully remove the chromosome 21 without damaging the integrity of the rest of the DNA in the nucleus.
Now I know some pro-lifers are immediately suspicious of this announcement thinking that it is meant to create a complete "cure" for Down Syndrome. A syndrome that many of us belief does not need a cure in the traditional sense. But looking closer, this technique was developed to help with some of the health problems of those with Down Syndrome, including an increased risk of leukemia. Dr. David Russell explains...Continue reading at LifeNews >>Hat tip: Refections of a Paralytic
I spent many, many, many hours in the lab testing people for mutations known to cause cystic fibrosis (CF). CF is a genetic disease caused by mutations in a gene called the CFTR gene. If a person has a deleterious mutation in both copies of his or her CFTR gene (one mutation inherited from dad, one from mom) then the CFTR protein that he or she produces does not function properly. Without a functioning CFTR protein, the patient produces abnormally thick mucus that collects in the lungs and pancreas causing serious breathing and digestive problems.
CF is a common genetic disease. It is estimated that 1 in 29 Caucasians carry a mutation in one of their two copies of the CFTR gene. Those that have only one CF mutation do not suffer from CF but are called carriers because they can pass this gene onto their children. There are over 1500 documented mutations in the CFTR gene and counting.
The sheer variation in these 1500 known CF mutations means that some people have mutations in both copies of their CFTR but do not have symptoms of CF. One of their copies of the CFTR gene works well enough to do the job.
I personally know such a girl. While the two mutations in her CFTR genes suggests that she should be sick (her parents were told that she would be while she was in utero), she is as healthy as any other girl her age. She does not have CF. Nor would any doctor diagnose her as a CF patient.
That is also the case for 11 year-old Colman Chadam. He is a healthy boy with mutations in his CFTR gene who has never been diagnosed with CF. And yet his middle school kicked him out simply because of his genes. (You know the DNA kind. Not the denim kind.)Continue reading at Creative Minority Report >>

So the other day on my blogging break my family made me sit down and watch the new Spider-Man movie, "The Amazing Spider-Man". I don't know why they had to make yet another Spider-Man flick, but for the sake of family unity I cuddled up on the coach and watched.
Recently, I hit a bunch of unsuspecting Catholic women at an innocuous book club over the head with the reality that transhumanist ideas are everywhere and that our children are soaking them up like a sponge. "The Amazing Spider-Man" was full of them.
I appreciated that the depiction of transhumanism, called "cross-species genetics" in the movie was a negative one. Dr. Connors, in a desperate attempt to keep his job and regrow his lost arm, injects himself with what I assume is a concoction of reptile DNA. In a total suspension of disbelief, Dr. Connors gets his arm back and then some when he turns into something horrific, the vile character of the Lizard that is whole, strong and, in the Lizard's opinion, superior to all humanity.
But Dr. Connors doesn't stop there. He wants the whole human race to share in his new found genetic superiority. He now understands that humans are weak and pathetic and it isn't good enough to fix us. He needs to change us and it is for our own good. In a monologue in the the depths of the sewer, Dr. Connors muses, "This is no longer about curing ills. This is about finding perfection." (At which point my 10 year-old son whispers to me, "Don't say a word, Mom. Don't say a word.") Dr. Connors, of course, attempts to bring all of New York City into his genetic nirvana.
I was heartened that Dr. Connors was such a tragic figure as super-heroes and villains with super powers have traditionally been. So why does the depiction of a lizard-man in a silly remake of a silly comic matter? Because I hear Dr. Connor's monologue everywhere coming from normal everyday people. People like this commenter at the transhumanist site Singularity Hub who tells us how he or she really feels about being human:
"Who doesn’t want to be smarter, prettier, healthier? Who doesn’t want to have wings to fly through the air, or gills to breathe under water? Are we stuck just being land dwellers? We spend most of our lives OBTAINING and MAINTAINING health, beauty, intelligence, etc., when we could be spending all this time and money obtaining and maintaining loving relationships with other people (transhumanists!) and going on adventures out to space exploring the universe, rather than stuck at home watching crap movies from Hollywood, going to school half our lives and drowning in debt because of it, and then just paying bills and taxes till you die. That’s no life, that’s SLAVERY.
Transhumanism is the answer to the racism, sickness, death, ugliness and stupidity. Transhumanism is the ultimate solution to be able to live up to our fullest godlike potential. The creative potential is limitless! I can’t wait to experience more, not being trapped inside these biologically frail, disease-prone bodies!
The screenwriters from "The Amazing Spider Man" could have put these exact words in the mouth of Dr. Connors. Take note that this person qualifies who "people" are: other transhumanists. Join them or be inferior, considered less than a person.Do your children a favor: use these super-hero movies as a way to talk about what it means to be human, how God loves us just the way we are, and going beyond curing disease and disability to changing our God-given nature is a disaster waiting to happen. My 10 year-old son can spot a transhumanist story line from a mile away. Can yours?
