Are earthquakes also earth burps? | Science/AAAS | News - 0 views

  •  
    An "excuse me" might be nice. Researchers have found that Earth belches a potent greenhouse gas known as tetrafluoromethane (CF4) during earthquakes and other tectonic events. The emissions likely aren't making a significant contribution to global warming, but the findings could change the way scientists model future climate scenarios. They also complicate the use of CF4 as a way to measure how the continents and climate have changed over millennia.

RNA | NOVA Labs | PBS - 0 views

  •  
    Nature's best kept secret is a wonder molecule called RNA. It is central to the origin of life, evolution, and the cellular machinery that keeps us alive. In this Lab you'll play the role of a molecular engineer by solving RNA folding puzzles. Then take your skills to Eterna, where you can design RNAs that could be at the heart of future life-saving therapies.

Should You Get The HPV Vaccine? - YouTube - 0 views

  •  
    HPV is considered one of the most common sexually transmitted infections, and it affects both men and women! Is it dangerous, and can it be prevented? Get your official DNews t-shirt here: http://www.forhumanpeoples.com/collec... Read More: Genital HPV Infection - Fact Sheet http://www.cdc.gov/std/hpv/stdfact-hp...

Antibiotic-Resistant Superbugs: Infections We Can't Cure? - YouTube - 0 views

  •  
    7:23 video Are we entering the post-antibiotic era? Antibiotic-resistant bacteria are on the rise, with millions of infections reported every year and thousands of deaths. How does antibiotic resistance work? How did we get here? And what can we do in the future to make sure that papercuts don't spell a death sentence?

High Tech High: Ebola: Going Viral - 0 views

  •  
    In the wake of a potential global crisis we will investigate the biology of infectious diseases to better understand how they transmit, replicate and induce an immune response in humans. Our objective is to pose solutions to the Ebola outbreak in the United States by studying other infectious diseases. We will investigate infectious diseases and the development of vaccines to show how they have changed the course of human health and populations as a whole. We will determine public perceptions about infectious diseases and identify misconceptions. Ultimately, we will develop community awareness information to manage and in future prevent an outbreak of Ebola.

A Lake in Bolivia Evaporates, and With It a Way of Life - The New York Times - 0 views

  •  
    High on Bolivia's semiarid Andean plains at more than 12,000 feet and subject to climatic whims, the shallow saline lake has dried up before only to rebound to a size twice the area of Los Angeles. But recovery may no longer be possible, scientists say. "This is a picture of the future of climate change," said Dirk Hoffman, a German glaciologist who studies how rising temperatures from the burning of fossil fuels has accelerated glacial melting in Bolivia.

What causes antibiotic resistance? - Kevin Wu - YouTube - 1 views

  •  
    4:34 video Right now, you are inhabited by trillions of microorganisms. Many of these bacteria are harmless (or even helpful!), but there are a few strains of 'super bacteria' that are pretty nasty -- and they're growing resistant to our antibiotics. Why is this happening? Kevin Wu details the evolution of this problem that presents a big challenge for the future of medicine.

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.

Scientists Seek Moratorium on Edits to Human Genome That Could Be Inherited - NYTimes.com - 0 views

  •  
    An international group of scientists meeting in Washington called on Thursday for what would, in effect, be a moratorium on making inheritable changes to the human genome. The group said it would be "irresponsible to proceed" until the risks could be better assessed and until there was "broad societal consensus about the appropriateness" of any proposed change. The group also held open the possibility for such work to proceed in the future by saying that as knowledge advances, the issue of making permanent changes to the human genome "should be revisited on a regular basis."

All Gene-Editing Research Should Proceed Cautiously, Scientists Conclude - Scientific A... - 0 views

  •  
    Tweaking the human genome with current and future gene-editing tools could lead to sophisticated treatments and prevention strategies for disease. The promise of those applications is reason enough to move forward with such work in the lab and clinic, albeit cautiously, the dozen scientists and bioethicists who organized the International Summit on Human Gene Editing said today after three days of deliberation and presentations in Washington, D.C.

Bark to the future: Ice Age puppies may reveal canine evolution | Science | The Guardian - 0 views

  •  
    "Thus far, the lineages of wolves that likely gave rise to dogs have not yet been discovered and it's possible that these puppies could be on that lineage, which would be very exciting," said evolutionary biologist Greger Larson, of the University of Oxford, one of the scientists behind a collaborative project aimed at finding out when and where dogs became the first domesticated animals.

Responding to a Changing Climate - National Center for Case Study Teaching in Science - 0 views

  •  
    This case study uses a jigsaw activity to introduce students to four specific plant responses to climate change: elevational range shifts, phenology shifts, community shifts, and changes in biodiversity. Students become "experts" on one of these responses by reading an article (from Nature, Science, or American Journal of Botany; not included with the case) on their assigned topic and then sharing their expertise with others in class. In order to hone their understanding and increase retention on these topics, students then learn about plant communities found in a specific system-vernal pools or seasonal wetlands typical of Mediterranean climates (a PowerPoint presentation on this topic is included). Students accomplish several small group tasks to assess how different vernal pool plant communities have responded to fluctuations in annual weather patterns and predict how these communities may respond to greater weather variability resulting from future climatic change. This case was written for mid- to upper-level ecology, plant ecology, botany, or environmental studies courses. The material covered may also be suitable for classes examining the role of weather variability/climate change in relation to plants.

Data Nuggets - 0 views

  •  
    Data Nuggets are free classroom activities, co-designed by scientists and teachers, designed to bring contemporary research and authentic data into the classroom. Data Nuggets include a connection to the scientist behind the data and the true story of their research. Each activity gives students practice working with 'messy data' and interpreting quantitative information. Students are guided through the entire process of science, including identifying hypotheses and predictions, visualizing and interpreting data, making evidence based claims, and asking their own questions for future research. Because of their simplicity and flexibility, Data Nuggets can be used throughout the school year and across grades K-16, as students grow in their quantitative abilities and gain confidence." Sounds like real science to me!
