Today is Valentine's Day. It is also National Donor Day (NDD). NDD focuses on five points of life: organs, tissues, marrow, platelets, and blood. Many nonprofit health organizations sponsor blood and marrow drives and organ/tissue sign-ups across the nation. National Donor Day was started in 1998 by the Saturn Corporation and its United Auto Workers partners with the support of the U.S. Department of Health and Human Services and many nonprofit health organizations.
Consider giving the gift that keeps on giving--become an organ and tissue donor. As a donor, you may save up to 8 lives through organ donation and enhance the lives of many others through tissue donation. Last year alone, organ donors made more than 28,000 transplants possible. Another one million people received cornea and other tissue transplants that helped them recover from trauma, bone damage, spinal injuries, burns, hearing impairment, and vision loss.
Unfortunately, thousands die every year waiting for a donor organ that never comes. You have the power to change that!
You can learn more about becoming a donor at the U.S. Department of Health and Services Web site, organdonor.gov

The Office of Science Education begins to review submissions to the NIH LAB Challenge
When we issued the NIH Lessons About Bioscience Challenge, we had no idea how many submissions we’d get. After all, it was our first online challenge and the first of its kind at the new Challenge.gov site. We wondered whether it was too broad, or too narrow. Were our instructions clear? Would submitters understand that we wanted an experimental procedure rather than a write-up of a completed research project? It looks like we did a pretty good job, because most entries were right on target.
We received more than 100 submissions from 20 states and Puerto Rico by the December 15 deadline. People heard about the challenge mainly through word of mouth and email listservs, and some cited Twitter and Challenge.gov as their source. The experiments cover a wide range of topics, from osmosis in chicken eggs to dragon genetics, and they target all grade levels.
Right now, we’re using a rubric to check that each submission meets our basic requirements. The ones that do will move on to the next phase. Some will be tested, and others will be reviewed by teachers and scientists before we announce the winners in March.
We want to send a hearty thank you to our several hundred submitters (most entries were by more than one person). We appreciate your efforts to help us bring the best science experiments to classrooms across the country. Stay tuned for updates!
Number of submissions: 108
How submitters heard about the challenge: Challenge.gov, 10; Twitter, 5; word of mouth, 33; other, 60
Geographic origin: Texas ,39; Maryland, 26; California, 6; Maine, 4; Colorado, 3; Iowa, 3; North Dakota, 3; Massachusetts, 2; Missouri, 2; Ohio, 2; Pennsylvania, 2; Tennessee, 2; Virginia, 2; and Puerto Rico, 2; and 1 each from Arizona, Florida, Illinois, New Jersey, New York, Oklahoma, and Washington (105 entries identified their state)
Targeted grade level of experiment: elementary grades K to 5, 42 (45%), middle school grades 5 to 8, 26 (28%), middle and high school grades 7 to 12, 13 (14%), and high school grades 9 to 12, 13 (14%)
The contest aims to challenge students to examine, question, and reflect on the important concepts of genetics. Essays are expected to contain substantive, well-reasoned arguments indicative of a depth of understanding of the concepts related to the essay questions.
Essays are read and evaluated by several independent judges through three rounds of scoring.
1st Place Winner: $1,000 + teacher receives a $1,000 grant for laboratory genetics equipment. 2nd Place Winner: $600 + teacher receives a $600 grant for laboratory genetics equipment. 3rd Place Winner: $400 + teacher receives a $400 grant for laboratory genetics equipment. Honorable Mention: 10 prizes of $100 each.

Top submissions will be accepted for publication in their online journal so that emerging young scientists like you can be recognized and your exciting work can be shared with the public.
My teenagers can’t imagine life before cell phones, while many of us wouldn’t want to. Such mobile devices are icons of the era, helping us connect with each other, manage tasks, play games, and access all sorts of information. A new application from the NHGRI, the Talking Glossary of Genetic Terms, falls into that last category. It has 200+ genetic terms that you are likely to hear in the news, in a classroom, or even from your health care providers.
Listen as leading NGHRI scientists pronounce and explain each term. Included are photos and short profiles of those scientists. Many terms are accompanied by helpful, colorful illustrations and 3D animations. You can take a quiz to test your knowledge, or suggest a term to a add to the app.
Check out the online version of the talking glossary. Pretty soon (by December, we hope!), you’ll be able to see how it is featured in the updated NIH Human Genetic Variation high school curriculum supplement.

A new studyby the American Society of Human Genetics (ASHG), the country’s leading genetics scientific society, found that more than 85 percent of states have genetics standards that are inadequate for preparing America’s high school students for future participation in a society and health care system that are certain to be increasingly impacted by genetics-based personalized medicine.
“Science education in the United States is based on testing and accountability standards that are developed by each state,” said Michael Dougherty, PhD, director of education at ASHG and the study’s lead author. “These standards determine the curriculum, instruction, and assessment of high school level science courses in each state, and if standards are weak, then essential genetics content may not be taught.”
According to ASHG’s study, which included all 50 states and the District of Columbia:
Only seven states have genetics standards that were rated as ‘adequate’ for genetic literacy (Delaware, Illinois, Kansas, Michigan, North Carolina, Tennessee, and Washington).
Of the 19 core concepts in genetics that were deemed essential by ASHG, 14 were rated as being covered inadequately by the nation as a whole (or were absent altogether).
Only two states, Michigan and Delaware, had more than 14 concepts (out of 19) rated as adequate. Twenty-three states had six or fewer concepts rated as adequate.
“ASHG’s findings indicate that the vast majority of U.S. students in grade 12 may be inadequately prepared to understand fundamental genetic concepts,” said Edward McCabe, MD, PhD, a pediatrician and geneticist who is the executive director of the Linda Crnic Institute for Down Syndrome at the University of Colorado. “Healthcare is moving rapidly toward personalized medicine, which is infused with genetics. Therefore, it is essential we provide America’s youth with the conceptual toolkit that is necessary to make informed healthcare decisions, and the fact that these key concepts in genetics are not being taught in many states is extremely concerning.”
“We hope the results of ASHG’s analysis help influence educators and policy makers to improve their state’s genetics standards,” said Dougherty. “Alternatively, deficient states might benefit from adopting science standards from the National Research Council’s Framework for K-12 Science Education, which, although not perfect, does a better job of addressing genetics concepts than most state standards that are currently in place.”

This year’s theme is building resilience in young children who are dealing with trauma. The idea behind the Awareness Day campaign is to draw attention to the importance of good mental health for healthy development. We were surprised to find out that last year, people held Awareness Day events at more than 1,000 sites, and almost 11,000 children and youth participated in them! Visit the Awareness Day home page in the coming weeks for updates on how to
lead an event,
find one in your area,
get helpful resources, and
broadcast timely, useful information through Facebook, tweets, and other social media.
As part of the campaign, one agency is posting information updates online about trauma and resilience in young children. The February update is about children who’ve been exposed to five or more “significant adversities” by the time they’re three years old: three out of four of them will experience delays in cognitive, language, and/or emotional development. “With help from families, providers, and the community, young children can demonstrate resilience when dealing with trauma,” according to the post. The March update states, “Studies on the brain show that physical, emotional, or sexual abuse in childhood can cause permanent damage to the brain, reduce the size of parts of the brain, [and] impact the way a child’s brain copes with daily stress, and can result in enduring problems such as depression, anxiety, aggression, impulsiveness, delinquency, hyperactivity, and substance abuse.” On the National Institute of Mental Health Web site (NIMH), you can find a booklet for parents on how to help children cope with and identify reactions to violence and disasters. Suggestions include
being straightforward about the event,
encouraging children to express their feelings,
maintaining routines, and
allowing children to make some basic choices for themselves.
You can also read about results from a recent NIMH study that emphasized the importance of having supportive and functional family relationships during childhood. The researchers found that “negative experiences early in life can have long-lasting effects on physical health, in addition to the known mental health consequences.”

The President and the First Lady opened the summit with a video about bullying and the growing movement to make our communities places where young people can thrive. The President explained that the goal of the conference was to “dispel the myth that bullying is just a harmless rite of passage or an inevitable part of growing up.”
The President says bullying is harmful and that it “doesn’t even end at the school bell -- it can follow our children from the hallways to their cell phones to their computer screens.” He asks people to join the stop-bullying campaign by visiting http://www.stopbullying.gov.
With computers and cell phones, cyberbullies may circulate aggressive messages far and wide, sometimes anonymously. Internet technology is increasingly in the hands of today’s youth, which has many benefits but also downsides with potentially far-reaching consequences. Tragically, the number of reports in the news of student suicides following incidents of cyberbullying is growing.
A recent NIH study notes that today’s children can’t always see who is bullying them, and this may be tougher to handle than traditional bullying. In fact, one of the study’s most notable findings was that cyberbully victims had higher depression scores over a 30-day period than did either the cyberbullies or the cyberbullies who are also victims.
The NIH study, based on a survey of students in grades 6 to 10, shows how prevalent cyberbullying is and the high rate of depression among victims. Cyber victims may not see or even be able to identify their harasser and may feel more vulnerable, isolated, and dehumanized at the time of attack than victims of traditional bullying, the study authors wrote in the Journal of Adolescent Health. Being bullied affects scholastic achievement, development of social skills, and general feelings of wellbeing, says Dr. Iannotti, the study’s senior author. Boys are more likely to be cyberbullies, and girls are more likely to be cyber victims. In an earlier study, the researchers noted that students were less likely to bully or to be victimized if they felt they had strong parental support.
The CDC reports that electronic aggression may peak around the end of middle school to the beginning of high school, and instant messaging appears to be the most common form of communication for cyberbullies. Victims of electronic aggression are significantly more likely than those who have not been victimized to use alcohol and other drugs, receive school detention or suspension, skip school, or experience in-person bullying.
These findings underscore the need to monitor and treat cyberbullying victims. First Lady Michelle Obama recently shared on the Today Show that she does not allow her children to participate on Facebook and is not a fan of young children using it. In fact, Facebook is restricted by law to users who are at least 13 years old.
The good news is that there’s a growing number of resources to help educators, parents, and students deal with cyberbullying.

It all started at my son’s wedding as I watched one of his groomsmen swaying at the altar, attempting to stay upright. As soon as the ceremony was over, we found him stretched out on a bench in the lobby. What followed was months of recovery, neurological tests, and consultations. He finally got the diagnosis: Parsonage-Turner syndrome, a rare disease of a group of nerves that runs from the spine through the neck and into the arm.
On Monday, February 28, the National Institutes of Health (NIH) will celebrate Rare Disease Day. The celebration will be on the main campus in Bethesda, Maryland. Attendance is free and open to the public. It’s one of the many ways NIH draws attention to our country’s 7,000 rare diseases. If fewer than 200,000 people in the U.S. have a disease, we consider it rare. About 80 percent of the rare diseases are genetic, and about half of them affect children. By raising awareness about these diseases, NIH shines a bright light on these often mysterious and underdiagnosed disorders.
The NIH Offices of Science Education and Rare Diseases Research are looking forward to the summer release of a new curriculum supplement for grades 6 - 8 that explores scientific inquiry through the study of rare diseases. Stay tuned for an announcement of its release in coming months!

An NIH-funded study shows our thoughts can manipulate computer images
Remember “The Matrix” movies? Characters in them are connected to a cyber world through a rod jammed into the backs of their heads. The cyber world can be influenced by thoughts and beliefs. The lead character, Neo, has to believe he’s “The One” so he can have the super powers needed to free humanity from the machines. Such science fiction technologies once seemed impossible, but not so much any more.
In an NIH-funded studyat UCLA Medical Center, Itzhak Fried and his colleagues showed that humans can regulate their neurons to alter a cyber reality, while being subjected to competitive stimuli. They worked with patients being treated for intractable epilepsy who’d had wires implanted into their brains. After connecting the wires to a computer, subjects were shown two merged images on a computer screen. With focused attention, they were able to force the computer to display one image and discard the other.
The brain-computer interface helps scientists understand how the brain processes information and how thoughts and decisions affect cell activity. The potential applications of the research are wide-ranging and could help paralyzed individuals communicate or control prosthetic limbs.
The results leave me wondering what’s next for our high-tech civilization.
Just the thought of sharing a bed with creepy-crawly critters is enough to give most of us the willies. But with the current epidemic of bedbug outbreaks, it’s becoming a living nightmare for people all across the country. Many of us will be traveling to visit family and friends over the holidays, making this an ideal time to learn how to protect ourselves from these pesky bugs. The CDC and EPA have come up with some great online resources for helping us prevent and deal with infestations, and life science teachers can use the sites to add a timely topic to their core curriculum.
Experts believe we’re experiencing a resurgence of bedbug outbreaks because people are traveling more, most of us don’t know how to prevent or handle infestations, and the insects are becoming resistant to many pesticides. Bedbugs are a problem, but if we do the right things, we can prevail!

An estimated 1.1 million Americans are living with HIV, and yet one out of five don’t know it. Today (December 1) is World AIDS Day. It is an opportunity for us to take action! Here are a few simple, powerful, and engaging ways:
Share information on Twitter about how you’re taking action for World AIDS Day (and beyond!) Use the official hashtag #WAD2010
Turn on the television these days, and you’ll hear news about the oil spill in the Gulf of Mexico and the ongoing cleanup efforts. You'll hear about the toll on wildlife and ecosystems, and about the health concerns for emergency responders involved in the cleanup. Such disasters, though devastating, can provide an impetus for us to learn more about the web of life on Earth. Sharing these lessons with the nation’s youth may help to safeguard our future, and better protect the health of the environment and ourselves.
The NIEHS has a variety of educational resources for K-12 teachers to help students explore the relationship between the environment and human health. Materials include teacher guides, lesson plans by grade level that can be integrated into existing curriculum, fact sheets, PowerPoint presentations, and online activities for students. Through the NIH curriculum supplement, Chemicals, the Environment, and You: Explorations in Science and Human Health, middle school students learn the basics of toxicology and explore the relationship between chemicals in the environment and human health.
Visit the NIEHS Gulf Oil Spill Response Efforts Web page for details on how NIEHS scientists are collaborating with others to protect and educate the public and to understand the health effects of exposure to cleanup workers and affected communities.

Suppose you’ve discovered that the genes responsible for (let’s say) Gina’s disease lie in a particular region of chromosome 3. You decide to sequence the DNA in that region to identify variants (mutations) that cause the problem. Unfortunately, there’s a lot of variation, so it’s not easy to link one particular variant with the illness. If you could just sequence the DNA of 10,000 people, you could figure it out.
As if! It’s possible to sequence DNA from many people in the same tube simultaneously but to do it, each DNA has to be labeled with its own “barcode” so its sequence can be matched back to the correct individual. Barcoding 10,000 DNA samples would take a long time and be very expensive.
Last year, researchers at Cold Spring Harbor Laboratoryfigured out a way to get around this problem.1 They decided to pool each person’s DNA with that of others, but instead of tagging each person’s, they put every individual’s DNA into several different pools.
How does that help? A simple example is shown in the figure. Suppose each person’s DNA is placed in five pools. If the sequence GACGGCATGTA is found in pools #1 #2, #3, #5, and #10 but not in any other pools, the sequence can be uniquely assigned to person AM because AM is the only person with DNA in all of those pools. Similarly, if the sequence AATTGCTAGCA is found only in pools #1, #3, #6, #8, and #10, the sequence can be uniquely assigned to person JS.
Of course, it may be simple to sort things out in a small sample, but imagine trying to do this if there are thousands of people and hundreds of pools. What’s a scientist to do? Enter ”DNA Sudoku.” It turns out that the same math used to determine the unique pattern of each Sudoku puzzle can be used to assign each DNA variation to a particular person. In fact, it’s theoretically possible to sequence more than 100,000 samples simultaneously. Once the technology is perfected, a project that would cost $10 million today may soon cost as little as $50,000.

The National Governors’ Association(NGA) and the Council of Chief State School Officers(CCSSO) lead the Common Core Standards Initiative. Its mission is to develop clear, rigorous standards for what students should learn in English language arts and math in every public school in every state in the country. Over the past few months, educators and states worked together to craft clearer and higher standards and drafted them into a coherent document. That collection of standards will become a gauge of the success in educating students and a guarantee that students who graduate are job and college ready.
The public comment period for the Common Core Standards ended April 2, 2010. The NGA and the CCSSO are making final adjustments to the document now, and they’ll release the final product to the states soon. Each state will set its own timetable for review and an adoption decision. Several states have already indicated an interest in moving ahead quickly and will begin the review process this spring, shortly after they receive the final document.
Although governors, state boards of education, and state legislatures rightfully will have the final say on the adoption of the Common Core Standards, many educators, business executives, and parents who are aware of the critical state of American education have been weighing in on the pro-adoption side. For example, Craig Barrett, former CEO of Intel, in an opinion article in the Wall Street Journal (April 6, 2010), stated, “I know that common education standards are essential for producing the educated work force America needs to remain globally competitive.” And Brian K. Fitzgerald, Executive Director of the Business Higher Education Forum(BHEF), said on April 7, 2010, “BHEF has endorsed the Common Core State Standards in mathematics and language arts, the adoption of which represents one of its top [preschool through high school] education priorities. In addition, BHEF has called for the adoption of science standards.”
The state-by-state decision process will evolve in the months ahead. Meanwhile, the fact remains that American students need to improve their academic skills relative to their international peers if we as a country are to continue to successfully compete in the world economy. The Common Core State Standards offer a way to develop the skills of all of our students while preparing them for college or a career.

Have you ever wanted to talk directly to the top minds in the field of genomics research? Well, get your thoughts in order and get those questions lined up because you will have the chance to chat one-on-one with experts in celebration of National DNA Day.
According to Carla Easter, Ph.D., science education specialist at the National Human Genome Research Institute (NHGRI), genomics and genetics experts will be available at the DNA Day Chatroom on Friday, April 23, from 8:00 a.m. to 6:00 p.m. EDT to answer questions from students, teachers, and the general public on topics such as basic genetics research, the genetic basis of disease, and ethical questions about genetic privacy. Transcripts from previous DNA Day chatrooms are also available on the NHGRI Web site.
One of my favorite exchanges from last year was, “What would someone do after getting their undergraduate degree if they were inclined to study DNA or genetics?” Current NHGRI director, Eric Green, offered up a list of options:
Get a job working in a genetics laboratory.
Become a genetics counselor.
Get a Ph.D. and become a genetics researcher.
Get an M.D. and become a medical geneticist.
Become a computer scientist and help us interpret information about our genomes.
In the Washington, D.C., metropolitan area, 35 NHGRI scientist ambassadors will be visiting schools through May to talk about job opportunities in genomic research. They will also help students plan their professional careers in genetics and genomics. For more information on potential careers in genomic sciences visit NHGRI's Genomic Careers Web Site.
The American Society for Human Genetics (ASHG) is sponsoring a variety of events that help K-12 students, teachers, and the public learn more about how genetics and genomics affect their lives. You can visit the ASHG DNA Day pagefor more information about ASHG-sponsored activities.
When I was in high school, I liked studying genetics. In particular, I liked the study of inheritance, and figuring out how to complete a Punnett square. At the time, I had no idea of the variety of careers available in genomics. Today’s career-hunting high school and college students can explore the nearly 50 career options at the The Genomic Careers Resource Web site, by the National Human Genome Research Institute.
The just launched career exploration Web site offers users an orientation along with many resources to help students find a career that suits them best. Explore the interactive options to:

For the Intel Science Talent Search (STS) competitionthis year, 300 semifinalists were chosen from among 1,736 entrants from high schools in 37 states and the District of Columbia. Each semifinalist received a $1,000 award for their research, and $1,000 was given to their school to further excellence in science, math, and engineering education.
The 40 finalistswere named January 27, and the final judging processwill be completed March 11 through 16 at the Science Talent Institute in Washington, D.C. The winner receives a scholarship award of $100,000.
Alumni of the Intel STS have made extraordinary contributions to science and hold more then 100 of the world’s most coveted science and math honors, including seven Nobel Prizes and three National Medals of Science.
NIH researchers and their mentees are enthusiastic about each other and their experiences together. Dr. Horvath says that Kristen is a brilliant student with impressive experience and knowledge in molecular biology and she was “perfectly matched with our lab.”
Dr. Venditti says that Conway contacted him after reading some of his lab’s papers on the NHGRI Web site. Conway’s experience opened his eyes to the world of medical research and how it is closely tied to the clinical aspects of medicine.
Lijin Dong said that Yifan came to the lab just like most high school students who have not been exposed much to the lab environment. “I worked with him on a daily basis by assigning readings, having discussions on the papers, and working through the logic of the project and lab skills,” he says.
I asked Yifan to explain his project so that other students would understand his work. He said, “Our project’s aim is to contribute to helping people who suffer from blindness -- in particular, age-related macular degeneration (AMD), a common retinal disease,- that leads to visual impairment. “
Yifan stimulated embryonic stem cell s to grow into a type of eye cell whose deterioration is heavily associated with AMD. With the continued succes s of stem cell research, he believes that “we may see a burst of transplantation studies in the future that could lead to medical advances in curing retinal disease. “
When I asked how he’s preparing for the final competition, Yifan said that he’s getting a poster ready for his presentation during the conference and learning as much as possible about retinal development, retinal disease, and the progression of stem cell research. “I want to be able to field any question from any judge competently and confidently, so that’s going to take a lot of preparation,“ he said.

When the news started pouring in about the effects of the earthquake in Haiti last month, I was startled by the devastation. The unexpected nature of the event, coupled with the destruction and loss of lives, made me wonder just how any one person, city, state, or country could really be prepared to handle such a disaster. Since then, I’ve found some resources that can help us plan ahead and cope with traumatic events when they do occur.
The Ready campaign is a national effort to help us prepare for and respond to natural and human-made disasters. Its goal is to increase the nation’s basic level of preparedness. The campaign includes Ready Kids, which aims to help parents and teachers educate kids about emergencies and how they can help their families get prepared. The program includes a Web site with online games and helpful resources for parents and teachers. At the site, kids learn how to create an emergency supply kit, make a family emergency plan, and learn more about natural disasters.
In just the past decade, the United States has experienced the September 11 terrorist attacks along with fires, tornados, mudslides, and other natural disasters. The National Institute of Mental Health (NIMH) conducts research on our reactions to these national crises and traumatic events. The Institute’s focus areas include traumatic stress reactions and mental health issues among military service members. Researchers have learned that people respond differently to crisis. Some have more intense feelings initially but eventually recover. Others need additional help and support, especially if they’ve experienced traumatic events before.
You can order or download free NIMH publications that could help you cope with traumatic events, including several in a series titled Helping Children and Adolescents Cope with Violence and Disasters:
Unique audio programs covering current health topics and medical research
Do you prefer to get your news by watching videos, listening to podcasts, or reading? For me, the answer would be listening or reading. Listening to news, an audio book or music is my favorite way to make good use of a long commute. For all the listeners out there, you can tune into some great NIH resources and hear about research discoveries, hot health topics and inside information from the scientific experts themselves.
Does this mean that we now have a single test for ADHD? Not quite. It means that there’s a measurable physiological difference between adults with and without ADHD. In time, this discovery may lead to a biochemical test for the condition.
The diagnosis of ADHD has been controversial because the characteristic behaviors -- impulsivity, daydreaming, and forgetfulness -- are within the extreme ends of the normal range of human behaviors.
Accurate diagnosis is important, because people who are underdiagnosed as children – and thus not treated -- may get into trouble constantly when their behavior clashes with what’s expected in certain environments, such as schools. Overdiagnosing can lead to unnecessary medication with stimulants, which carry risks of side effects.

NLD connects teachers, students, scientists and community volunteers for hands-on learning. (See White House release.)
U.S. students will now have more chances to do what comes naturally -ask questions, explore, and test life's boundaries to better understand their world when President Obama announces a National Lab Day today.
The first NLD, scheduled for May, 2010, will celebrate community hubs - collaborations among volunteers, students and educators. But it doesn't end there. NLD is a nationwide initiative to build new and foster ongoing hubs for the long-term. Through these hubs, students can design, build, experiment, and explore in a real laboratory.
What is a real laboratory? It's any place a student can explore, experiment, and test. We're not just talking about test tubes and beakers. A lab could be a laptop to a software designer, a mountaintop to a geologist, a computer link to a distant particle accelerator to a physicist, or a factory floor to an industrial engineer. It's a place where lessons in science, engineering, and technology can be designed to happen, or where math can come alive. It could be anywhere in the physical or virtual world.
The NLD Website will support hands-on learning across the country by serving as a place where educators and scientists will be able to connect to potential partners in their area and to find out what is happening around the country. The site will also help them find resources to support, improve, and streamline their efforts.
In April '09 President Obama said "I want us all to think about new and creative ways to engage young people in science and engineering, whether it's science festivals, robotics competitions, fairs that encourage young people to create and build and invent -- to be makers of things, not just consumers of things." NLD does just that.
On Oct. 5, 2007, three American researchers -- Elizabeth H. Blackburn, Carol W. Greider, and Jack W. Szostak -- were awarded the Nobel Prize in Physiology or Medicine. This marks a milestone because it’s the first time two women have shared a Nobel prize. In a recent online interview, Blackburn said the honor for her and Greider is “a hopeful sign” for women. In the future, she said, people will say, “Oh yes, it’s not too unusual to have women getting Nobel prizes. Two got one this year. I hope it becomes very normal.” You can listen to the scientists’ reactions to The Call announcing their award at the Nobel Web site.
Their story begins with chromosomes, the giant complexes of DNA and proteins found in our cells. When cells divide, they make a copy of each chromosome, so the daughter cell receives a full complement of DNA. The enzymes that control this process can’t quite copy the chromosome all the way to the end, so a little bit of the chromosome is lost every time a cell divides. Enter the telomere and our Nobelists’ research.
Telomeres are short regions of repetitive DNA that sit at the ends of chromosomes but don’t encode any genes. When a cell divides, the telomeres get shorter, not the business part of the chromosomes. With each cell division, the telomeres get shorter. Scientists believe that this telomere shortening is in part responsible for the limited lifespan of most cells. However, some cells, including stem cells that live for the life of an organism, can replace telomeres through the action of the enzyme telomerase.
Telomerase is turned off in most cells, but it’s reactivated in many cancer cells. This allows the cancer cells to replicate many more times than normal. This has opened the possibility of treating cancer by zeroing in on telomerase. Clinical trials are under way to evaluate vaccines directed against cells with elevated telomerase activity.
The Nobelists’ research also opens up a wide range of investigations into the roles that telomeres and telomerase play in aging. This is because as we age, more and more of our cells have shortened telomeres. Some cells with short telomeres die while others “senesce,’ which means they remain in place but can’t divide and have reduced functional capacity. If we have too many senescent cells, normal processes are less efficient, and repairing even minor damage becomes difficult.

Probably everyone reading this has had the flu at least once in their lifetime. The flu is a contagious respiratory illness caused by influenza viruses that infect 5-20% (that is as many as 1 out of 5 people) of people in the U.S. each year. Is it serious? More than 200,000 people are hospitalized and about 36,000 people die yearly from the flu.
The best way to prevent the flu is by getting a flu vaccination each year. Unfortunately, many of us don't know where to get vaccinated, forget about it, or are simply more afraid of shots than the flu. (A big mistake!) Undoubtedly, a lot more people would be vaccinated if, like tetanus vaccinations, we only had to get a shot every ten years or so. So why can't we?
Normally when we are vaccinated, we are injected with small parts of molecules called 'epitopes'. Our immune system responds by making 'memory cells' that specifically recognize those epitopes. At a second encounter with that epitope, these memory cells help the body mount a much stronger and quicker immune response than the first time. Thus, after a flu vaccination, when the real flu virus tries to attack, our memory cells go to work and usually stop it before we feel sick.
Unfortunately, unlike tetanus which is caused by a single bacterium, flu can be caused by two different families of viruses (called group 1 and group 2). Worse, within these families are many different subtypes each of which has different epitopes. Because of this, every year, scientists have to make some informed guesses as to which type of flu will be common next year and then make the appropriate vaccine.
A discovery by a group of scientists in the United States and another group from Europe and Hong Kong may make the '10 year flu vaccine' a reality. These scientists identified an epitope that appears to be common to the members of the group 1 influenza virus family. Using this epitope, a vaccine was made that was able to prevent death in mice that were challenged with lethal doses of flu viruses. It even protected them against the H5N1 'bird flu' virus.
Hopefully vaccines generated by this epitope will be potent enough, that a single vaccination given every few years will be enough to protect us against all group 1 influenza viruses. Now if scientists can just find a common epitope for group 2!

On June 22, President Obama signed a bill that he hopes will help kids make the choice not to use tobacco, the Family Smoking Prevention and Tobacco Control Act. Do you have any idea how many people under age 18 will smoke a cigarette for the first time today? Three and a half thousand, and a third of them will become regular users! One goal of the new law is to reduce the number of young first-time users to 1,000.
The federal government will now be regulating the content, marketing, and sale of tobacco products. The law banishes Joe Camel and other youth-oriented advertising gimmicks and bans fruit-flavored tobacco products. You won’t be seeing colorful billboards of happy people holding cigarettes within 1,000 feet of playgrounds filled with grade-schoolers at recess. In fact, all tobacco advertising within 1,000 feet of schools is now illegal.
In response, we wouldn’t be surprised if more states started promoting tobacco education efforts like New Jersey’s. There, students at every grade level study the nature of tobacco and its physiological, psychological, sociological, and legal effects on themselves, their families, and society under the state’s Core Curriculum Content Standards and Comprehensive Health and Physical Education Curriculum Framework. To find out whether your state has tobacco education standards – and for lots of interesting facts about kids and smoking -- visit the Campaign for Tobacco-Free Kids.

I'm Gina, a research scientist working in the Office of Science Education. I believe that we are all scientists! I will be highlighting people we don't normally think of as "scientists" who have had a huge impact on science. Perhaps you can tell me about people you know who have used science to make life in the classroom or at home a bit easier. Stay tuned for my White House series on how U.S. presidents have contributed to the advancement of science in the own unique ways. I will try to keep you in-the-know about some of the newest scientific discoveries and what they might mean so that you can dazzle friends and neighbors with you science knowledge. You can use today's tidbit for that!
DNA evidence gathered from a crime scene may be great to convict a suspected criminal, but what if you don't have a suspect? Scientists in the Netherlands have taken a first step in solving that problem. They have developed a method to predict eye color based on DNA. Other scientists are working to develop more reliable methods for determining hair and skin color. Combining these new methods with other established methods for inferring a person’s geographical origin could provide law enforcement with a powerful tool to identify an unknown suspect.
The method has a number of other applications, notably, as a way to predict susceptibility to diseases, such as heart disease, diabetes, and some cancers, which are influenced by numerous genes.
Of course, a lot of work still needs to be done yet to turn this into reality.
