Will Bugs Replace Beef?
Cattle and other livestock create tons of damaging greenhouse gases. There may be one environmentally friendly solution: eating bugs. But will anyone go for it?
Even when you consider how many insects you would need to equal the meat of a single pig or cow, the difference is enormous. For instance, a pig produces anywhere between ten and a hundred times as much greenhouse gases per kilogram as mealworms would. Ammonia emissions also seem to drop dramatically. Pigs create about ten times as much ammonia per kilogram as crickets do, and perhaps fifty times as much as locusts. Considering ammonia can wreak havoc on the acidity of groundwater, a big reduction like that could have tremendous benefits for the land as a whole.

- Some are even designated as World Heritage Sites because humans don't go there at all, while others have felt the effects of too much human influence.
- These 7 UNESCO World Heritage Sites each represent an overlooked or at-risk facet of humanity's collective cultural heritage.
An innovation may lead to lifelike evolving machines.
- Scientists at Cornell University devise a material with 3 key traits of life.
- The goal for the researchers is not to create life but lifelike machines.
- The researchers were able to program metabolism into the material's DNA.
A new method promises to capture an elusive dark world particle.
- Scientists working on the Large Hadron Collider (LHC) devised a method for trapping dark matter particles.
- Dark matter is estimated to take up 26.8% of all matter in the Universe.
- The researchers will be able to try their approach in 2021, when the LHC goes back online.
