Biotech v. Sustainable Agriculture
Are biotechnology and sustainable agriculture complimentary or contradictory? The Economist moderates an online debate between experts in the field.
Biotechnology and sustainable agriculture are complimentary, says Pamela Ronald, professor of plant pathology at the University of California, Davis: "The number of people on Earth is expected to increase from the current 6.7 billion to 9 billion by 2050. How will we feed them? Genetically engineered crops will play an important role." Her opponent in the debate is Charles Benbrook, chief scientist at the Organic Center: "Biotechnology is not a system of farming. It reflects no specific philosophy nor is it guided by a set of principles or performance criteria. It is a bag of tools than can be used for good or evil, and lots in between," he says.
Giving our solar system a "slap in the face"
- A stream of galactic debris is hurtling at us, pulling dark matter along with it
- It's traveling so quickly it's been described as a hurricane of dark matter
- Scientists are excited to set their particle detectors at the onslffaught
Two massive clouds of dust in orbit around the Earth have been discussed for years and finally proven to exist.
- Hungarian astronomers have proven the existence of two "pseudo-satellites" in orbit around the earth.
- These dust clouds were first discovered in the sixties, but are so difficult to spot that scientists have debated their existence since then.
- The findings may be used to decide where to put satellites in the future and will have to be considered when interplanetary space missions are undertaken.
Once again, our circadian rhythm points the way.
- Seven individuals were locked inside a windowless, internetless room for 37 days.
- While at rest, they burned 130 more calories at 5 p.m. than at 5 a.m.
