Next Generation Microscopy: Goodbye Purple Fingers - No Stain Microscopy
Test results can often take hours or even days because cells or tissues must be subjected to lengthy fixation and labeling processes, sometimes called staining, in order to visualize and distinguish cellular components. In addition to long processing times, staining procedures often include harsh treatments or conditions that alter the tissues themselves, making interpretation of results difficult.
A newly developed label-free imaging technique called stimulated Raman scattering (SRS) will likely revolutionize biomedical imaging in research and diagnostic laboratories. A team lead by Sunney Xie at Harvard University reported this new technique in the December 19 issue of Science.
Xie is enthusiastic about the ways in which SRS imaging will facilitate progress in many fields. "Applications of SRS imaging range from mapping distribution of small metabolite and drug molecules in cells and tissues to medical diagnosis of cancer. Neuroimaging is another exciting area of application."

On Becoming Independent - Hands-off Teaching/Hands-on Learning
This idea of working hard and doing something is essential to personal pride and satisfaction with one's place in life, I think. From my personal observations, poor people are not respected or treated as if there is something in life that they CAN do, do it well, and enjoy doing. Regrettably, urban schools are so frustrating and confusing that children aren't given the chance to truly learn. They forced to listen and regurgitate and get it right the first time. Learning, particularly hands-on learning is thrown away by 4th grade. This hands-on learning is much like the act of learning a craft, becoming skilled at something. My employees did not want to work hard, so no value in it and as a result struggled to fit into the work place and it very program that was supposed to help them out of poverty seemed to fail them.

Science Blogging Conference will address Diversity in Science
The 2009 ScienceOnline Conference will take place MLK weekend in Research Triangle, North Caroline. This conference is like many other Blogging Conferences - networking, increasing readership, moneytizing, and improving your blog. Like other "special interest blogging groups" the participants will address important matters of concern to them.
Since I've talked about race issues, particularly, my race (African-American) and STEM diversity, I'm tempted to just offer them links to my previous posts. I still might do that, but I offer this first - an abstract I ran across on ERIC. It is an abstract of a paper presented at the Annual Meeting of the American Educational Research Association (Montreal, Canada, April 1983).
"The differences in the personality and social backgrounds of college students majoring in science and nonscience fields were assessed with 91 black and 109 white students. The following categories of majors were compared: natural science, social science, and nonscience (education, business, history, and all others). The personality and attitudes of students were assessed by the 16PF, Bem Sex-Role Inventory, and the Attitude Toward Women Scale. Data were also collected on birth order, number of siblings, and social class. The black natural science majors were from a higher social class and more practical and toughminded than were the black social and nonscience majors. The white natural science majors were more masculine sex-role oriented and more sober than were the white social and nonscience majors. In comparison with nonscience majors, natural science majors were more often first born and from higher social class families with fewer siblings. There were more racial differences found than college major differences; however, black and white science majors were more similar than black and white students in the other two college major groups. It is suggested that knowledge about the characteristics of black scientists may be helpful in identifying prospective scientists. "

This paper/data was presented 25 years ago. A whole generation ago. I wonder what new insights we have today?
Here is another paper, something more recent, that is also very interesting.

Say It Ain't So...NPR News & Notes Cancelled
Yes, you read or heard right. N&N and the lovely Farai Chideya have been invited to leave the NPR line-up. Get the details at We Love You! (And, Yes, We Are Cancelled). March 20 will be their last day.
I am sad. First Bryant Park Project, now News & Notes. It's like the Horror film where the Black Actors always go first. I enjoy almost all of the NPR news programming. And I really enjoyed the African-American/Minority American programs and angles. I thought it brought more issues to the mainstream conversation.
Is there anything we can do to stave this off? Hey, African-American Radio Consortium, any ideas?
And something a little more recent:

Diluting Baby Formula can be fatal. Spread the word.
These lean economic times can lead many people to tighten their belts. Stretching food across several meals is a natural way to make due. But in an effort to cut a few corners and save money, one mom learned a hard lesson. Warning: A little water can hurt babies—So don't dilute infant formula. The Florida mom had been diluting her baby's formula to stretch out her monthly ration from WIC. She didn't know (and neither did I) that it can cause water intoxication which can be fatal. This is such a sad but very realistic problem. With poor people doing what they can to survive they become more vulnerable to mistaken fatalities.
In an effort to ration food and supplies, we should all work to find ways to cut back AND help one another. I don't want another family to suffer like this. I is a shame that some programs give families a hard time when they need to adjust their receivings - soy milk instead of traditional forumula, or switch brands because some formulas aren't received well by some babies. There is no one size fits all in nutrition or social services.

Food Democracy Now - Real Change We Must Embrace
Food. It is a necessity. However, many people are completely blind to how our food is grown, raised, processed and distributed. Food processing is no easy task - at a local level (the farmer and processors) or on a large scale (big agribusiness, distribution, and preservation).

NSF-AAAS Student Research Conference Underlines the Importance of Historically Black Colleges and Universities
John Haynes, Professor and Dean of Science and Mathematics at Morehouse College, Atlanta

In 2004 nearly half-49%-of bachelor's degrees in physics and 39% in chemistry awarded to African-Americans came from historically black colleges and universities (HBCU), according to a recent report by the Commission on Professionals in Science and Technology and the American Institute of Physics. One well-known HBCU, Morehouse College in Atlanta, graduates more bachelor's degrees in science per year than some countries, said John K. Haynes, professor and Morehouse's dean of Science and Mathematics, who spoke at the conference.
According to Shirley Malcom, director of Education and Human Resources at AAAS: "We must invest in development of talent and potential for science and engineering. HBCUs provide access to many students and introduce them to the possibilities of education and careers in STEM." HBCUs, she said, "contribute disproportionately as the baccalaureate origins institutions in many fields that are crucial to U.S. competitiveness and national security."
Much of the research described by HBCU undergraduates at the event directly addresses pressing national needs. For example, a poster headlined "Preparation of Biodiesel from Waste Oil" presented by Ashley White, a junior chemistry major at Jackson State University, Mississippi. Asked why the work is important, she responded: "Because we need cheaper gas! And we need to stop depending on foreign oil. We can do this ourselves." She went on to describe the chemistry involved in converting discarded vegetable oil used for cooking into diesel fuel. The quality of the fuel is acceptable, she added, but the process needs to be improved for greater yield.
Another poster described research in steganography, an area that turns out to be important for national security. The poster's presenter, Kevin Harris, a junior applied math major at North Carolina A&T State University, defined steganography as "disguising information without arousing suspicion." One virtually undetectable method is to encode a message within a digital graphics file by tweaking the data bits in a way that leaves the image unaltered. While this sounds like something out of a James Bond movie, Harris cited a recent FBI White Paper on the subject that shows its seriousness in an age of terrorism.
These two posters were among some 275 student poster presentations and over 100 talks at the four-day HBCU-UP conference, held 23-26 October in Atlanta. The presentations covered virtually every major field of science and technology, with cash awards offered for the best research as chosen by a panel of experts. This is the second year under a three-year NSF grant that the AAAS has organized a student-oriented event with the atmosphere and format of a full-scale scientific conference, this year with over 800 attendees. The conference featured student research abstracts in a glossy program book and gave the students opportunities to explore offerings from various graduate schools and employers.
The student activities were supplemented by workshops, and plenary talks from some of the leading players in science, technology, engineering, and mathematics (STEM) education at HBCUs. James H. Wyche, director of the NSF Division of Human Resource Development, Directorate for Education and Human Resources, spoke of the significance of STEM education for global competitiveness and noted the importance of key "transit points" in keeping potential and current HBCU science students on track toward their careers, such as the transition from 11th to 12th grade.
Haynes, in his plenary address, emphasized the excitement of today's forefront science and the importance of a research experience in undergraduate science education. Carlton E. Brown, president of Clark Atlanta University, another major HBCU, reported large numbers enrolled in STEM courses at his institution but noted that graduation rates are lower than desired. He said raising the number and skills of qualified middle- and high school science teachers would be crucial for improving university-level graduation rates in those fields.
In a later conversation, Haynes placed HBCU training within the framework of a national commitment to STEM education. "The country realizes it's got to tap all of its resources," he said. "Other countries are producing many more students in science. The question is whether we have the national will. The next president has to send a clear message to the country that all of its citizens should receive quality education." As a critical factor, Haynes added, that should include pre-college education.
For some students, the conference gave an opportunity to reflect on their HBCU experience along with their research. Jasmine Greene, a sophomore biology major at Lemoyne-Owen College, Memphis, Tennessee, presented work on the interaction between chromium metal ions and the neurotransmitter aspartate. Even trace amounts of certain metallic elements can impair human neural behavior. Greene's project is the first to examine possible harmful effects from chromium. The results will be submitted to the Journal of the American Chemical Society.
When asked about the pros and cons of attending a historically black college compared to a school with a diverse population, Greene responded that while she strongly favors diversity, an HBCU offers "a family bond."
"The teachers really care," she said. "I'm not just a number."
Justin Morrissette, a graduating senior in chemical engineering at Hampton University in Virginia, gave a different response to the question. Morrissette studied viral infections of bacteria in the Pacific Ocean, which could have consequences for the prevalence of plankton and the food chain that it supports. He carried out his research partly at institutions that are not HBCUs; for him, the most important thing in choosing where to learn and work was to follow the science.
The buzz of activity around the student presentations was matched by the buzz of activity around the conference exhibits. Over 80 exhibitors and recruiters, mostly representing graduate schools across the United States but also from employers such as the U.S. Naval Research Laboratory and the U.S. Environmental Protection Agency, illustrated that the pool of HBCU undergraduates is indeed a valued resource for further STEM education and jobs.
For all the activity and student enthusiasm, however, the current economic downturn could potentially alter federal and other funding for science education including HBCUs and their supporting programs. Some HBCUs suffer from lack of the resources needed to provide complete student research experiences. Bad economic news may trigger other problems because "many of these students need financial help to go [to college]," said Yolanda George, deputy director of AAAS Education and Human Resources. "Many of the students come from rural areas--first-generation college students."
Added Malcom: "We can anticipate tough budget years ahead for R&D, to the extent that these can be considered a 'nice to have' rather than a 'must have.' If, however, R&D become necessities or, better still, investments, we can make a case for support even in tough times."
Haynes sounded perhaps the most optimistic note of all. Even in the face of financial difficulties, he said, we should realize that "global awareness is where we're going so internationalizing the experience of students is the next new frontier... We have to get young people out of [provincialism] to see there's a wide world with opportunities."

New Sickle Cell Anemia Treatment discovered
Thanks to hard work, patience, and scientific pursuit of knowledge and application there seems to be New Hope for Sickle-Cell Anemia Sufferers. According to a report in Science Magazine,
Researchers have discovered the molecular switch for activating the fetal form of hemoglobin—the iron-containing protein in red blood cells that transports oxygen—which could help alleviate the symptoms of genetic blood disorders, including sickle-cell anemia.
Sickle anemia is widely regarded as a Black disease because it affects an estimated 70,000 people (mostly African-Americans) in the U.S. But it in fact peoples from many regions of the world have high incidences of this disease in their populations: Africa, Mediterranean countries (such as Greece, Turkey, and Italy), The Arabian peninsula, India, and Latin America (such as South America, Central America, and parts of the Caribbean).
Sickle-cell anemia can be fatal with most people dying by their mid-40s. When I was a young child, persons with sickle-cell anemia had a life expectancy of 25. Thank goodness for modern medicine. However, it is a high-maintenance disease. Sufferers deal with extreme pain in the legs when their red blood cells sickle and prevent a constant flow of oxygenated blood. Many take blood thinners or have frequent blood transfusions to stem the symptoms. This new treatment technique may by-pass all of that. Inherited forms of anemia may soon be treated by turning on a gene normally active only in the womb, when individuals with sickle cell anemia are asymptomatic. Read more about this new discovery at Scientific American.

Public Libraries as Egalitarian Institutions
Though funding varies from place to place, most modern libraries have free computer and internet access for any member of the public. Competition for these computers can be fierce, but it is available. Also, libraries offer free literacy classes, GED preparation, and computer lessons. They also serve as community meeting places.
Public Libraries are great education resources. Support your library, host an informal class or make a donation. It’s for everyone – all ages, all education levels, all economic levels. Few institutions are truly as egalitarian as our libraries.

Science Vocab: Heritability
Here’s a pop quiz. Read the following statements and select the best answer from the choices below.
A: Snoring runs in my family; it is genetic.
B: Snoring runs in my family; it is heritable.
1. Statement A is true
2. Statement B is true
3. Both Statement A and B are true
4. Neither Statement A or B are true
5. Don’t know
The answer: Only Statement B can be true. Heritability deals with the likelihood or probability of traits running in families. But here is the catch: something can be heritable due to genetics or environment. In this case the environment includes culture or habits and behaviors that you experience and accept as a normal and everyday. Everything that shared among related individuals isn’t necessarily because they share the same genes.
Here’s another snag – heritable traits and inherited traits are not synonymous. To inherit something means you received it or get from your parents. Think about an heirloom. Your grandfather has this amazing fishing pole. When he passes on, he gives the fishing pole to your father and your father gives it to you. You get the exact same thing your father and grandfather had. Genetic inheritance works the same way. One parent has a gene or allele and he or she gives to you.
Heritability is the likelihood of getting something…in other words, you might get it. It’s not automatic – like genetic inheritance, but the chances look good.
Here’s an example: Autism: highly heritable but not inherited
Arthur L Beaudet of Baylor University examined genetic causes of Autism. He found specific gene disorders that can result in autism de novo, automatically or off the top. These disorders include an alteration of the genome causing complete loss of copy, gain of copy or disruption of a dosage-sensitive gene.
But research by Sebat et al. indicates that other genomic deletions and duplications may point to genes in which mutations may lead to autism, but doesn’t automatically cause autism. In other words, having these genes doesn’t mean you will automatically have autism, but your chances are high.
Thinking about human behavior and habits, many of us confuse genetic and cultural heritability, especially when comparing family members to one another. If it’s something positive like – good looks or being smart, then it is thought to be an asset. You feel like you’ve got the deck stacked in your favor. "Natural with no extensions. She get it from her mama."

Affirmed - McCain/Palin are Anti-science.
First McCain put his foot in the mouth at Debate #1 about the Grizzly Bears.
Correction - The money spent on this genetics and conservation research project was not an earmark. It was a awarded as a competitive grant and help shed light on an endangered species - a native American species- and apex predator.
Next McCain sounded like a foolish old man comparing the Zeiss Projector at the historic Aldler Museum of Chicago to an overhead projector in Debates #2 and #3.
Correction - the projector projects images of the night sky and space onto a domed ceiling in the Sky Theater. Adler is the Western Hemisphere's oldest Planetarium. They educate and inspire millions. For decades children of Chicago, the state of Illinois, and the US are have been provided top-notch space and planetary sciences education and career exploration opportunities. In fact, the Adler has educated Navy men in night sky navigation to help them chart their courses while out at sea. The stars of the night sky are their only landmarks. The Navy, the US Navy. Hmm, should Mr. Naval Academy know how important the Adler is...Maybe he would if he hadn't been such a bad boy in college and graduated near the bottom of the class.
Last, Mrs. Palin talked about a "ridiculous pet project research on fruit flies in Paris", just moments after declaring her commitment to families with special needs childrend and disabled family members. Palin, autism and fruitflies - it does not add up
Correction - 1st, the research which as she correctly stated was paid for by NSF was actually conducted in the United States! And this research with fruit flies has made discoveries about genes and proteins related to Autism Spectrum disorders! Foot in the mouth.
UNC scientists comment in support of fruit fly research for understanding autism
McCain-Palin just seem so under-informed and unapologetically ignorant about science, science education, science outreach, and research. It bothers me to potentially have another adminstration that marginalizes science as a meaningful endeavor and politicizes research results, ignoring sound advise when making important policy decisions.
Having a President (and Vice President) who are scientifically literate matters.

Inmates Conduct Ecological Research on Slow-growing Mosses
The Moss-in-Prisons project promotes the rehabilitation of prisoners.
Credit: Nalini Nadkarni of Evergreen State College.
Re-post: NSF Press Release 08-186
October 17, 2008
Nalini Nadkarni of Evergreen State College currently advises a team of researchers who sport shaved heads, tattooed biceps and prison-issued garb rather than the lab coats and khakis typically worn by researchers. Why is Nadkarni's team composed of such apparently iconoclastic researchers? Because all of her researchers are inmates at Cedar Creek Corrections Center, a medium security prison in Littlerock, Washington.
With partial funding from the National Science Foundation (NSF), Nadkarni has guided her unlikely but productive team of researchers since 2004, as they conduct experiments to identify the best ways to cultivate slow-growing mosses. Nadkarni's so-called Moss-in-Prisons project is designed to help ecologists replace large quantities of ecologically important mosses that are regularly illegally stripped from Pacific Northwest forests by horticulturalists.
Why did Nadkarni recruit inmates into her research team? "Because," she explains, "I need help from people who have long periods of time available to observe and measure the growing mosses; access to extensive space to lay out flats of plants; and fresh minds to put forward innovative solutions."
In addition to managing the Moss-in-Prisons research at Cedar Creek, Nadkarni helps the facility's inmates run various projects that promote sustainable living--including an organic garden that produces 15,000 pounds of fresh vegetables every summer, a bee-keeping operation and a composting operation that processes one ton of food per month.
One member of Nadkarni's research team, who was released from Cedar Creek, enrolled in a Ph.D. program in microbiology at the University of Nevada and presented his Cedar Creek research at the annual meeting of the Ecological Society of America in August 2008. (Heck, no. Now that's Broader impact.)
Nadkarni started the Moss-in-Prisons project with a type of NSF award that is specially designed to help scientists reach out to public audiences. More recently, she has received additional funding from the Washington State Department of Corrections.
In addition, Nadkarni has creatively stretched project resources by recruiting other NSF-funded researchers to contribute to a popular lecture series that she started at Cedar Creek. By giving such lectures, these scientists fulfill requirements for conducting public outreach that accompany NSF awards.
A recent TV news report about the Moss-in-Prisons and the sustainability projects at Cedar Creek is posted at http://www.kcts9.org/video/green-prison-reform.

Stand Up Against Poverty
The talk is done. It’s time to take Action.
The United Nations needs every concerned person to help bring the Millennium Development Goals to fruition. End Poverty by the year 2015.
From October 17 to 19, people all around the world are asked to Stand Up and Take Action, in a global mobilization to stamp out poverty and inequality. The world has made strong and sustained progress in reducing extreme poverty, but this is now being undercut by higher prices - particularly of food and oil - and the global economic slowdown, according to the UN’s Millennium Development Goals Report 2008. Read it for yourself, here.
Here’s the Action. Stand Up and Take Action.
Join an event this weekend.
Spread the word.
There are several dozen events here in the US. Join one make your voice heard and actions count to stamp out poverty and hunger in this world in our lifetime.

More Blog Action – Hunger Awareness
Poverty and Hunger are twin sisters. My Blog Action Day Post on Poverty is only the springboard of Awareness. Do you realize how important food production is to life? Do you realize that a single digit percentage of the world’s population is responsible for growing and harvesting enough food to feed the entire world? Most of these farmers are US farmers in what we affectionately call the Bread Basket.These farmers, ranchers, and processors already deal with climate and ecological stoichasticity – too much or little rain or sun, locusts or other invertebrate pests. They take on the risk and if things go bad there’s less food to go around. Now we have Global Warming to deal with. And have you thought about how this crappy global economy will test everyone? Less food and more expensive and less to go around.
But there’s one thing different about these twin sisters – Poverty tends to be heritable but Hunger is universal. When food is limited even the strongest and wealthiest suffer, though last and for shorter durations.
Today is World Food Day. October 16th is a worldwide event designed to increase awareness, understanding and informed, year-around action to alleviate hunger. America is no exception and the poor of America will suffer first and hardest. Food Insecurity & Food Justice will be our charge for this coming year.

Blog Action Day: Poverty
I believe that service – contributing your talent and time to accomplish a goal for the betterment of a community – is way to resolve important matters. Serving others and making this world a better place is a noble calling. And I don’t think concept of service belongs to conservatives or liberals or Christians or any other religious group. It is non-partisan. It is a common ground. If those of us who care to serve and believe in service work to help others, then I believe we can create a just society where poverty no longer exists.

Science Nobel Prize Winners Announced
I know the US Political Theatre has most of us wide mouth. But the world of science and discovery is steady at the helm. The Nobel Foundation has named its 2008 winners in the science categories.
Doctors Osamu Shimomura, Martin Chalfie, and Roger Tsien share The Nobel Prize in Chemistry for their discoveries of the green florescent protein in jellyfish
Here’s what they did.
Doctors Yoichiro Nambu, Makoto Kobayashi, and Toshihide Masukawa share The Nobel Prize for Physics for their discoveries of broken symmetry dynamics. Don’t even ask me what this means. I understand the chemistry and physiology/medicine award. I need to go back to school to figure this out. But nonetheless it’s important. Bone up, read about it here.
Doctors Francoise Barre-Sinoussi, Luc Montagnier and Harald zur Hausen share The Nobel Prize in Physiology or Medicine – the discoverers of the Human Papilloma virus and the HIV Virus . By the way this award is for most any life science discipline. Dr. Robert Gallo also did some key research on the HIV virus wasn’t co-award the prize. Science Drama.
Go to Happy Hours this weekend and impress the socks off of everyone. For good measure throw in some chatter about the folks throughout history who were worthy but did not get the award. The most notable un-awardee is perhaps Rosalind Franklin who did all of the real work that Watson &Crick are now famous for. Coincidentally her research work cost her her life.

Science Vocab: Dulosis - Slave-making in Ants
The Parasite species exploits the parent care (brood care) of another species. They steal pupae from another species (the host species). An all-out fight ensues between the species and it is not pretty. Ants die…lots and lots of ants die. If the raiding party is successful they will kill the workers of the host species leaving too few to worry about. The raiding party carry the kidnapped pupae to their nest where they complete their development. The pupae stage is the last metamorphosis. Pupae require no special care for food. It is very much like the cocoon stage of a butterfly.
Days later pupae emerge as fully adult worker ants and accept the Parasite Queen and parasite workers as their own kin and commence with the jobs they were kidnapped to do – raising the larvae of the Queen. Sounds eerily familiar to slave dynamics in the Americas. Slaves were kidnapped from Africa, brought to the New World and forced to work the plantations and females often nursed and cared for the young of the owners.
But like all tenuous relationships, there are is co-evolutionary war at hand. This has and will always occur when two individuals or groups have a relationship but conflicting goals. This, too is eerily familiar.
The host species have some defenses against this colony attack and pupae kidnapping, for a long time, everyone thought that these defenses must all be pre-take-over defenses. And that makes sense. These Pre-take over defenses include enemy recognition and physical defenses (fighting) against the parasites. At the same time, no one really thought that post-taker defenses were possible. For one, once the ants emerge they smell the odor of the colony and imprint to it, and everyone thought this locked everything in place. Plus, no one imagined a scenario of rebellion. What good would it do the kidnapped ants to rebel? They can’t “go back home”. They wouldn’t know where it is, besides, everyone was killed in the battle to take them as pupae.
But according to some research by Susanne Foitzik, rebellion can happen and she has documented it. She studies ant species are found in the northeast United States, Atlantic Region: slavemaking ants Protomognathus americanus and Harpagoxenus sublaevis and their hosts Temnothorax spp. and Leptothorax spp.

Even after the slave ants have accepted their “new home” there have been some recorded incidences that slave workers will actually kill the larvae of the parasite brood they were supposed to raise...but only the female larvae. In some cases slave workers actually attack, mutilate and rip the larvae apart. In other cases, the workers will simply neglect the larvae by not feeding them and discarding them in “dump piles” in the nest. Some host species are more vicious than others with some species more likely to rebelling than others.
Why would this happen? Well the running reason has to do with the fact that perhaps the slave workers are keeping the Brood colony in check. By doing so, they prevent or decrease the number of raids on nearby host colonies that are likely to be comprised of their relatives…a sort of indirect group selection.
But how do they know which pupae belong to which species? It seems the chemical and olfactory cues – hydrocarbon profiles are different for each species; and the slave worker ants can distinguish between the female pupae of their own species and that of the parasite species. However, they cannot distinguish between male pupae of their own or parasite species.
And this is why some think the workers don’t kill male pupae. The proposed answer is believed to be related to odor…male larvae “smell” different than female larvae and some experiments suggest that the male larvae of parasite species smell a lot like the male larva of the host species. Moreover, male ants aren’t considered a real threat. Males don’t participate in colony affairs like work, defense, or raiding other ant species nests. Simply put, males mate, then die.

Lack of Diversity in Science is Bad for our Nation, Economy.
Study says that Lack of African-Americans in Science Field Hurting Industry.
by J. Coyden Palmer
A study that surveyed Fortune 1000 STEM (science, technology, engineering and mathematics) executives representing leading science and technology companies in the United States, was released last week by Bayer Corporation.
The survey found that women, African Americans, Hispanics and Native Americans are underrepresented in science, technology, engineering and mathematics fields and that the result could hurt the nation as a whole. The findings of the study should alarm whoever is going to be the next president of the United States the report stated. Minorities are seen as perhaps the saving grace for the country if America is going to keep its place as the leader in the STEM industry, the report noted.
Read the rest of the report on BDPA Foundation page.
I am cross-posting this article because this is one of my battle cries. The need for enhanced diversity in STEM fields - beginning with enhanced education and outreach opportunities to members of these under-represented groups.

Assertive STEM Education Training Programs may prove beneficial
Why 'Perfect Representation' in STEM is important
I am also a staunch supporter of community involvement and initiatives that reach out to these groups. So even if the school system can't handle it (for whatever reason) I believe and know that there is plenty of talent and energy that can pick up the slack and provide students with supplement STEM education.
I dedicate some of my time and energy to share science with students - in my real life, not just online. I participate in a variety of outreach programs from mentoring and training students in research, guest speaking, tutoring and service in my professional organizations.
So, with that in mind I want to encourage everyone to find a way to get involved to close the math & science achievement gap in this nation. Tutor. Assist with a Science Fair or Knowledge Bowl or National Computer Competition or any other academic program or fair. Have your company sponsor a Family Math and/or Science Night at the school or local community center.
Something. In fact, here's something you can do right now - and if you can leverage company or organization support that is great.
DonorsChoose is an annual fundraiser that raises money to supply classrooms with the things they need. Won't you help students at low-income schools* get the supplies they need to get a quality science and math education?
*(Schools with a high proportion of students receiving free and reduced lunches).
There is also a Blogger Challenge to get Communities of Bloggers to raise a high amount of funds. I know Blog Communities like ScienceBlogs do it every year. I'll look into the details and see if I can get members of the AfroSphere/AfroSpear to participate.
Maybe we call all do our little part.

Presidential Candidates Stand on Science
The other day, I blogged about the Presidential Candidates’ stands on science. STEM is the foundation of this nation’s prowess, security, and success. Therefore sound science policies and developing other policies with sound science and advice is terribly important.
Too bad there won't be a 4th Presidential Debate that's all about Science and Education. But we've got the next best thing - ScienceDebate2008. It is an online forum where the candidates provided answers to 14 key Science questions. The goal is to raise public awareness of science, technology, and innovation and call attention to informed decision-making at higher political levels. You can read their answers and offer comments and offer new questions.
McCain doesn’t even mention a single science agency and all of his focus is on technology and entrepreneurship. Basic research happens at colleges adn universities and through scientific agencies like NSF, NASA, and NIMH. Business innovation of technology and discovery takes place AFTER graduate students and post-docs work out all of the kinks. I am disturbed by McCain’s limited comprehension STEM and its work culture. He completely disregards the role of academics in science research, and it makes him seem so out of touch. He complete focuses on tech-related industries (I guess because of the potential for entrepreneurship) and ignore the basic sciences such as life sciences and physical sciences. And I’m still sore about the comment about science research being a wasteful pork earmark.
Let me share something with you all. The ability to get federal research money for science is based on a very strict, very competitive peer-reviewed system. You have to write a detailed grant explaining why you want the money and the impact the research/results will have on the world. Science is about knowledge – gaining knowledge, clarifying information, and disseminating knowledge. Even great ideas that might possibly change the world get denied because of lack of impact. Getting research money is no easy task. Even for my graduate-level research monies I had to jump through several hoops. No one passes this money out. There is no special money set aside for pet science projects –of any kind. Everyone must compete and demonstrate professional ability before any money is granted.
Update: From Campaign News from AAAS Policy Alert Newsletter.
On Sept. 26 the Obama campaign released a revised plan for science, technology, and innovation and a letter signed by 61 Nobel Prize-winning scientists who have endorsed Obama. On Sept. 29 Senator McCain released a radio ad reinforcing his past record on stem cell research and calling an Obama ad claiming that he has "stood in the way" of stem cell research "misleading." And in a speech last week at the Clinton Global Initiative, McCain reiterated his commitment to addressing global warming.
Stay informed!
I can’t wait for the VP Debate tomorrow.
