A mother who didn't believe in vaccines for years is now writing about her experience after all seven of her children became sick with whooping cough and hopes to inspire other parents to reconsider vaccination.

 A team of scientists has announced that the age of the synthetic chromosome is upon us, as a study published in Science today reveals how the group was able to construct a yeast chromosome from scratch - an experiment that allowed the team to make fully functional "designer yeast."

With support from the National Science Foundation, we assisted in developing bioinformatics curriculum for high schools and popular bioinformatics tutorials that are used in both college and high school classes. We have shared these materials at several Bio-Link workshops, and at workshops sponsored by CCURI, Tulsa Community College (SEEDBed award), and DelMar College.  Digital World Biology is also partnering with the Amgen Biotech Experience at Shoreline Community College to assist in providing professional development opportunities for high school teachers.

This case study presents the story of "Nick," a student who has been assigned the task of writing a research paper describing the fundamentals of chemical bonds and how they relate to human life. When Nick experiences difficulty remembering information about the different types of chemical bonds, he turns to his tutor, Josh, for help. Josh explains orbitals and valence electrons to Nick, and then they together review nonpolar and polar covalent bonds, ionic bonds, and hydrogen bonds. A final practical application exercise requires that students write about how different types of chemical bonds may relate to the development of Alzheimer's disease and to the mechanism of action of potential drug treatments.  The case is presented with PowerPoint slides and is designed to be used with a personal response system ("clickers"), but students can instead record their answers on paper or share them verbally.  The content is appropriate for use in high school and undergraduate introductory chemistry and biology courses.

You're probably aware of eight basic blood types: A, AB, B and O, each of which can be "positive" or "negative." They're the most important, because a patient who receives ABO +/- incompatible blood very often experiences a dangerous immune reaction. For the sake of simplicity, these are the types that organizations like the Red Cross usually talk about. But this system turns out to be a big oversimplification. Each of these eight types of blood can be subdivided into many distinct varieties. There are millions in all, each classified according to the little markers called antigens that coat the surface of red blood cells.

This hands-on activity, used in conjunction with the film The Making of the Fittest: Natural Selection in Humans, teaches students about population genetics, the Hardy-Weinberg principle, and how natural selection alters the frequency distribution of heritable traits. It uses simple simulations to illustrate these complex concepts and includes exercises such as calculating allele and genotype frequencies, graphing and interpretation of data, and designing experiments to reinforce key concepts in population genetics.

Meet five fellow Pompe patients as they recount their own experiences with the diagnostic journey. You are sure to find bits of your own story in theirs. The road to diagnosis can be riddled with uncertainty, an array of specialists all looking for an answer, and even misdiagnosis. That is undoubtedly why many people living with Pompe welcome the moment a physician delivers the correct diagnosis. Finally, an answer; a name for what has been happening all these years.

This site provides biochemical methods and computer tools to allow students to use their own DNA "fingerprints" as a starting point in the study of human evolution. Two experiments are currently available, which are supported by reagents and ready-to-use kits available from Carolina Biological Supply Company.

The NISE Network offers a variety of programs and activities designed for small and large groups in different settings. Educational programs are a great way to introduce audiences to nanoscale science, engineering, and technology. Presenters can choose a format and topic that is appropriate for their audience. Facilitated experiences foster visitor conversation and interaction, and allow educators to adjust the science content, pace, and delivery style to suit their audience.

You may remember neuroscientist Miguel Nicolelis - he built the brain-controlled exoskeleton that allowed a paralyzed man to kick the first ball of the 2014 World Cup. What's he working on now? Building ways for two minds (rats and monkeys, for now) to send messages brain to brain. Watch to the end for an experiment that, as he says, will go to "the limit of your imagination."

Halfway through our walk to the hospital I regained my composure. Of course I had not been instantaneously struck by an incredibly rare disease that, by the way, takes at least 12 hours after consumption to manifest and does not share many symptoms with your garden variety anxiety attack. My experience had been shaped by my mindset. A decade of learning about the psychological power of expectations could not inoculate me from its effect.

Sonnenburg, his wife Erica, and the graduate student Samuel Smits confirmed this idea in a recent experiment. The researchers started with mice that had been raised in sterile bubbles and then loaded with identical collections of gut microbes. They then fed these mice a high-fiber diet, before randomly switching half of them to low-fiber chow for seven weeks. Predictably, the fall in fiber caused upheavals in the rodents' guts. In the low-fiber group, the numbers of 60 percent of the local microbe species fell dramatically, and some remained low even after the mice returned to high-fiber meals. Those seven low-fiber weeks left lingering scars on the animals' microbiomes.

This case study presents the story of Phil, an undergraduate majoring in biology, whose Russian cousin Dimitri has contracted tuberculosis (TB) from inmates at the prison where he works.  Phil learns that his cousin's failure to complete his antibiotic regimen likely contributed to the evolution of antibiotic-resistant TB in his body.  Phil consults with his friend Stacy, and together they try to understand Dimitri's condition by applying what they are learning in their genetics lab experiment about the role of random mutation in bacterial evolution (including the development of antibiotic resistance) through Luria- Delbrück fluctuation analysis. The same analysis includes calculation of the mutation rate, which Phil realizes is sufficient to cause MRSA and other antibiotic-resistant infections. This case study was originally developed for concurrent use in freshman/sophomore-level genetics, elementary statistics, and precalculus. However, it is also very appropriate for courses in introductory biology, evolutionary biology, and biostatistics. The teaching notes discuss various ways to run the case depending on the mathematics and biology background of students.

Avida-ED is an award-winning educational application developed at Michigan State University for undergraduate biology courses to help students learn about evolution and scientific method by allowing them to design and perform experiments to test hypotheses about evolutionary mechanisms using evolving digital organisms.
