Physicist Brian Cox visited NASA’s Space Power Facility in Ohio to observe two objects — a bowling ball and a feather — dropped in vacumn chamber — the world’s biggest vacuum chamber to be exact:
How can consciousness be addressed scientifically? The Tucson conference, founded in 1994 and celebrating its 20th anniversary in 2014, exemplifies the quest. What are the range of theories? Where do participants position themselves? Meet the founders, early visionaries, new scientists and thinkers. Progress is being made, but what does this really mean?
Genetically Engineered Food is Safe: No Evidence that GE Crops are Unsafe to Eat, or Do Damage to the Environment
“The inescapable conclusion, after reading the report, is the G.E. crops are pretty much just crops. They are not the panacea that some proponents claim, nor the dreaded monsters that others claim.” — Wayne Parrott a professor of crop and soil sciences at the University of Georgia.
A two-year analysis of almost 900 journal articles on the past 30 years of genetically modified, or engineered (GE), crop use concludes that there is no evidence that GE crops are unsafe to eat, or do damage to the environment. The 400-page report — Genetically Engineered Crops: Experiences and Prospects’ published by the National Academies Press on Tuesday, May 17, 2016. — was conducted by 20 scientists, and commissioned by the US National Academies of Science, Engineering, and Medicine.
The report looks at the impacts GE crops have had since the 1980s. Its findings include:
- Generally positive economic outcomes for farmers, but no indication GE crops changed the rate of increase in yields;
- Decreased crop losses, insecticide use and greater insect biodiversity for insect-resistant Bt crops, but also instances of insects evolving resistance;
- No decrease in plant biodiversity for herbicide tolerant crops, but a major problem with herbicide-resistant weeds due to heavy glyphosate use;
- No evidence that foods from GE crops are less safe to eat than conventional food.
Looking to the future of GE crops, the report notes that new genetic technologies are blurring the line between conventional and GE crops, and that the U.S. regulatory system needs to assess crop varieties based on their individual characteristics, not the way they are produced.
Set foot on an alien world, on average three to four billion miles from the warmth of the sun.
On July 14, 2015, NASA’s New Horizons spacecraft zipped past Pluto, scanning the dwarf planet in unprecedented detail. Using data from that flyby, The New York Times created a seven-minute virtual reality film. Fly over Pluto’s rugged surface, stand among the icy al-Idrisi Mountains and touch down in frost-rimmed Elliot Crater. The film was produced in collaboration with the Lunar and Planetary Institute and the Universities Space Research Association.
