Glowing Plants on Kickstarter - National Center for Case Study Teaching in Science - 0 views

  •  
    This case study is centered on a real scenario from 2013 in which the Kickstarter fundraising platform included a fundraising proposal from a group wanting to use synthetic biology to make glowing plants. The proposal raised controversy because the Glowing Plant group offered to give away their genetically-modified glowing plant product to investors.  Kickstarter subsequently changed its policy to prevent use of genetically modified organisms as rewards or incentives to investors. This case study was developed for a college first-year seminar focused on the ethics of synthetic biology, and was introduced during the first week of the semester. The case uses the jigsaw teaching method to introduce students both to the mechanics of synthetic biology and to questions about how we should distribute the benefits and burdens associated with new or emerging technologies. It could be adapted for courses in introductory college biology, genetics or bioethics.

Can synthetic biology save wildlife? From re-creating extinct species to the risk of ge... - 0 views

  •  
    What effects will the rapidly growing field of synthetic biology have on the conservation of nature? The ecological and ethical challenges stemming from this question will require a new and continuing dialogue between members of the synthetic biology and biodiversity conservation communities, according to authors of a new paper.

Scientists just took a major step toward making life from scratch | The Verge - 0 views

  •  
     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."

Unlucky Chucky and Toxins of the Neuromuscular Junction - National Center for Case Stud... - 0 views

  •  
    Signaling at the neuromuscular junction (NMJ) is a complex process that is required for many actions that sustain life within humans. Toxins that act upon the NMJ, both natural and synthetic, act in a variety of ways to inhibit this function. This case study examines how a variety of toxins can act to disrupt the normal mechanism of function of the NMJ  by placing a protagonist ("Unlucky Chucky") at an eco-spa in Colombia with his good friend Melody. Unfortunately, during their time at the eco-spa, things don't always turn out well for Chucky. A variety of neuromuscular toxins are discussed including curare (d-tubocurarine), Botox (botulinum toxin A), physostigmine and sarin gas (GB). This case was designed to be used in a variety of classrooms ranging from an undergraduate introduction to biology course in a module focused on neuromuscular functioning, to an introduction to physiology course as an introduction to the NMJ; it could also potentially be used in a nursing course that is examining NMJ physiology.

New "Bionic" Leaf Is Roughly 10 Times More Efficient Than Natural Photosynthesis - Scie... - 0 views

  •  
    Chemist Daniel Nocera of Harvard University and his team joined forces with synthetic biologist Pamela Silver of Harvard Medical School and her team to craft a kind of living battery, which they call a bionic leaf for its melding of biology and technology. The device uses solar electricity from a photovoltaic panel to power the chemistry that splits water into oxygen and hydrogen.

'Genetic firewall' holds engineered microbes captive | Science/AAAS | News - 0 views

  •  
    Human-engineered microbes are workhorses of the pharmaceutical and chemical industries, churning out biofuels, drugs, and many other products. But they can cause big problems if they become contaminated by other microbes or viruses or escape into the environment. Now, a new type of microbe that can survive only on artificial nutrients promises better security against such mishaps. The strategy, described in two papers in this week's issue of Nature, might ultimately be used to control genetically engineered plants or other organisms released into the wild to create products or clean up pollution.

Mission | Genetic Literacy Project - 0 views

  •  
    Genetic and biotechnology can improve food security, the environment and public health. Yet dramatic innovation can lead to unintended consequences and present ethical challenges. In theory, the study of genetics and related cutting edge sciences are widely celebrated. But in practice, the words "gene" and "genetic engineering" often stir fear and misunderstanding when applied to biomedicine and farming. Intricate science scares people who don't understand risk and complexity. What is the potential of agricultural and human genetics? The commitment of the GLP is to promote public awareness of genetics and science literacy.
