• A comment on Conversation: Would you eat "in vitro" meat?

  Jan 5 2012: According to one study, the impact would be: it would use 35 to 60 percent less energy, emit 80 to 95 percent less greenhouse gas, and use around 98 percent less land. (http://www.reuters.com/article/2011/11/11/us-science-meat-f-idUSTRE7AA30020111111)
  
  Would I eat lab-grown meat? Sure. Am I ready to give up steak for it? Probably not at this stage.

• A comment on Conversation: What are potential applications for Temporal and Spatial Cloaking?

  Jan 5 2012: It does not cause a hole in time, so much as using the properties of optical fiber to make two different light beams travel different paths at different speeds. So spacetime isn't bent or anything weird like that. Matter inside the effect will still behave normally, just be in complete darkness. Temporal cloaking just makes things more invisible.

  A comment on Conversation: Food Rationing would be more effective than using Supply and Demand.

  Jan 5 2012: Well, that's a tangle of ideas. Obesity is a complex issue and not even the experts agree how best to permanently reverse it. Some say diet and exercise, some say that it is more of a hormonal imbalance and genetic disposition. If we can engineer our diets to reverse obesity, and increasing longevity, then it shouldn't be too much harder to make food just as tasty and fulfilling as the food we eat now.
  
  We will probably have to give up raising animals for meat and instead grow meat artificially. If we did that, it would use 35 to 60 percent less energy, emit 80 to 95 percent less greenhouse gas, and use around 98 percent less land. We could then use that savings to increase food production for those who go hungry. (http://www.reuters.com/article/2011/11/11/us-science-meat-f-idUSTRE7AA30020111111)
  
  Rather than ration our food, I'd vote for food being so satisfying and so fulfilling that we stop naturally instead of having someone else prevent us from eating.

  A comment on Conversation: Is tissue engineering the future of medicine? Es la ingenieria de tejidos el futuro de la medicina?

  Jan 5 2012: It is not an impossible dream. Currently, we can produce skin, bone, arteries... simple stuff. Micro-kidneys to assist renal function and pancreatic cells to produce extra insulin are possible (in lab rats today). I believe, fairly soon, we will produce artificial organs. These organs that will not be simple clones of our organs, but bioengineered to enhance our biological function from modified adult stem cells and advanced materials.
  
  (traducción automática) No es un sueño imposible. En la actualidad, podemos producir piel, huesos, arterias ... cosas simples. Micro-riñones para ayudar a la función renal y las células del páncreas para producir insulina adicional es posible (en ratas de laboratorio en la actualidad). Creo que, muy pronto, vamos a producir órganos artificiales. Estos órganos, que no serán simples clones de nuestros órganos, pero la bioingeniería para mejorar nuestra función biológica de modificar las células madre adultas y materiales avanzados.
