Geographical Association - Ebola crisis 2014 - 0 views

  •  
    Ebola is an infectious disease, which has become a pandemic crisis causing around 5000 deaths in 2014, with a 50% mortality rate among those who have contracted the virus. The outbreak in West Africa was first reported in March 2014, and every natural case of Ebola has been in Sub-Saharan Africa with Liberia, Sierra Leone and Guinea at the epicentre of the crisis. This key stage 3-5 resource, produced by GA Consultant and Secondary Phase Committee Co-Chair Stephen Schwab, includes classroom activities and teaching ideas, and explores geographical facts, concepts and the impact the virus has had on the communities affected.

  •  
    In the February 19, 2014 issue of Science Translational Medicine (Sci Transl Med. 2014 Feb 19;6(224):224ra24), Bettegowda and colleagues in the Sol Goldman Pancreatic Cancer Research center at Johns Hopkins report on an exciting approach to the detection of pancreatic cancer. Bettegowda and colleagues applied cutting edge DNA sequencing to blood samples from a large number of patients with a number of different cancers. They found that many cancers, even some small curable cancers, shed mutant DNA into the blood.

Got Blood? - National Center for Case Study Teaching in Science - 0 views

  •  
    The Aedes aegypti mosquito is the major vector for transmission of numerous viral diseases, including yellow fever, dengue, and now, Zika. Interestingly, different subspecies of A. aegypti are known to exist in close proximity but with considerable genetic divergence between them. One major difference between a "forest" form and a "domestic" form is a strong preference in the latter subspecies for human over non-human blood biting. This difference was explored with genetic and neurophysiological approaches by a research group at Rockefeller University and published in a 2014 paper in Nature. This flipped case study uses parts of the Nature paper to focus on elements of the scientific method as well as evolutionary questions raised by the difference in biting preference between the two subspecies. Students prepare for class by watching a video that provides background information about the published study that forms the basis for the case. In class students then work in groups to develop a hypothesis, predictions and proposed experiments to test the idea of different biting preferences.

Ebola Evolved Into Deadlier Enemy During the African Epidemic - The New York Times - 0 views

  •  
    The Ebola epidemic that tore through West Africa in 2014 claimed 11,310 lives, far more than any previous outbreak. A combination of factors contributed to its savagery, among them a mobile population, crumbling public health systems, official neglect and hazardous burial practices. But new research suggests another impetus: The virus may have evolved a new weapon against its human hosts. In studies published on Thursday in the journal Cell, two teams of scientists report that a genetic mutation may have made Ebola more deadly by improving the virus's ability to enter human cells.

More People Are Seeking Genetic Testing, But Counselors Aren't Keeping Up : Shots - Hea... - 0 views

  •  
    She says people became much more willing to talk about their genetic predispositions and seek out testing for conditions like Alzheimer's disease and cystic fibrosis. The number of patients seeking genetic counseling and testing has increased dramatically, according to a 2014 study that looked at how Jolie's announcement affected interest in testing. But the number of genetic counselors, the people who help both doctors and patients make sense of these tests, hasn't expanded enough to keep up with that demand. There are just 4,000 certified genetic counselors in the country today. That's one for every 80,000 Americans.

BSL-4: Authorized Personnel Only - National Center for Case Study Teaching in Science - 0 views

  •  
    This case study is based on the 2014 Ebola epidemic that spread to multiple highly populated countries in West Africa, making it the largest and most devastating outbreak in the history of the virus. The storyline, inspired by a compilation of factual information, unfolds through a fictional narrative wherein students play the role of an infectious disease specialist in training to learn about the techniques used in the detection, diagnosis, and management of Ebola virus outbreaks. The story is presented as an interrupted "clicker case" that combines problem-based case teaching methods with simulated biological laboratory inquiry through the use of Case It, a free molecular biology software, along with the NCBI's online bioinformatics tools and databases. Students work in groups to collaboratively explore various biological and social aspects of this infectious disease outbreak. This case was developed for senior students at the secondary level and can be modified for use in an introductory biology, microbiology, or epidemiology course at the undergraduate level.

    4:00 video 93% of Americans agree that sex education should be taught in schools, but what's the best approach to get teens to practice safe sex? Read More: Sex Education Delays Teens' Sexual Activity http://www.huffingtonpost.com/2012/03... "Teens who receive formal sex education wait longer to have sex, a new study finds - and when they do get around to doing the deed, they're more likely than teens who haven't had sex ed to use contraception." Sex Education in the U.S. is Screwing Our Kids http://www.salon.com/2014/12/01/why_s... "Government-funded abstinence programs and a lack of instructor training are failing the country's teens." Teaching Good Sex http://www.nytimes.com/2011/11/20/mag...

Miguel Nicolelis: Brain-to-brain communication has arrived. How we did it - YouTube - 0 views

  •  
    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."

Fill up your gas tank with bamboo? | Science/AAAS | News - 0 views

  •  
    2014 was a banner year for making automotive fuel from nonfood crops, with a series of major new production plants opening in the United States. However, producing this so-called cellulosic ethanol remains considerably more expensive than gasoline. So researchers are always on the lookout for new ways to trim costs. Now they have a new lead, a microbe that can use abundant nitrogen gas as the fertilizer it needs to produce ethanol from plants.

Blood From Ebola Survivor Yields Clues For New Vaccines And Antibody Drugs - Forbes - 0 views

  •  
    But this tiny sample turned out to hold tremendous scientific value. It was from a person fortunate to survive the deadly Ebola virus outbreak of 2014. Walker and her colleagues wanted to know if they could identify some special antibodies in that person's blood. If this person had special Ebola-neutralizing antibodies, that might help explain why that person lived. The antibodies might also help provide a template for future development of a vaccine. Or, they could be the basis for genetically engineered copies that could be manufactured at large scale, stockpiled and used to rescue people newly infected in an outbreak.

First robust genetic links to depression emerge : Nature News & Comment - 0 views

  •  
    By early 2014, Flint, Kendler and a team of collaborators had analysed DNA sequences from 5,303 Chinese women with depression, and another 5,337 controls. As Flint expected, 85% of the depressed women had a severe form of the disorder called melancholia, which robs people of the ability to feel joy. "You can be a doting grandparent and your favourite grandchildren can show up at your door," says Douglas Levinson, a psychiatrist at Stanford University in California, "and you can't feel anything." The analysis yielded two genetic sequences that seemed to be linked to depression: one in a stretch of DNA that codes for an enzyme whose function is not fully understood, and the other next to the gene SIRT1, which is important for energy-producing cell structures called mitochondria. The correlations were confirmed in another set of more than 3,000 depressed men and women and over 3,000 controls.

Protein Targeting Gone Awry - National Center for Case Study Teaching in Science - 0 views

  •  
    This case study synthesizes students' knowledge of the central dogma and cell structure by examining a rare health disorder in order to understand protein targeting and its medical consequences. Students first identify the molecular alteration in affected members of a family with renal Fanconi syndrome as reported in the New England Journal of Medicine (2014). Students then use an online bioinformatics tool to analyze the wildtype and mutant proteins and examine their subcellular localization. Finally, students use this information to explain the symptoms of affected family members. The case is delivered with a PowerPoint presentation that includes a selection of brainstorming prompts and "clicker questions." Students complete a worksheet (included in the teaching notes) before class, making the activity suitable for a flipped classroom. A second worksheet (also included in the teaching notes) is completed during class. The case is written for an introductory biology course for majors, but could also be used as a unit capstone in a non-majors human biology course; the case is also scalable to upper division courses in physiology that specifically explore kidney function.
