Race Is On To Stop Fungus That Could Wipe Out 80% Of World’s Wheat

Race Is On To Stop Fungus That Could Wipe Out 80% Of World’s Wheat

Scientists working to develop wheat varieties resistant to a strain of “stem rust” 

The Ug99 fungus, called stem rust, could wipe out more than 80% of the world’s wheat as it spreads from Africa, scientists fear. The race is on to breed resistant plants before it reaches the U.S.

Dinosaur Extinction Occured 300,000 Years After Asteroid Impact

Dinosaur Extinction Occured 300,000 Years After Asteroid Impact

A giant asteroid hit the Earth around 65million years ago, but experts dispute the impact it had. 

Molten droplets from the ancient asteroid impact were found just below the Cretaceous-Tertiary boundary – a geological layer of sediment linked with the extinction.

EPA Declares Greenhouse Emissions Endanger Human Health

EPA Declares Greenhouse Emissions Endanger Human Health

Total U.S. greenhouse gas emissions were 7,282 million metric tons carbon dioxide equivalent in 2007, an increase of 1.4 percent from the 2006 level.The U.S.

Environmental Protection Agency on Friday declared that greenhouse gas emissions like carbon dioxide endanger human health and welfare, clearing the way for possible U.S. regulation.

How Microbes Can Fuel America In The Future

How Microbes Can Fuel America In The Future 

Scientists Use Tiny Organisms to Create Fuel, Viruses to Make Batteries

For millenniums, microbes have been a staunch technological ally. They have leavened our bread and cured our cheeses. Now, engineers are asking them to convert carbon dioxide into fuel and to build a new generation of batteries. Some of the smallest life forms with which we share the planet are helping us cope with the energy challenges of the 21st century.

Virgin Galactic Will Fly You To Space And Monitor The Climate

Virgin Galactic Will Fly You To Space And Monitor The Climate 

 Virgin Galactic’s WhiteKnight

Virgin Galactic’s WhiteKnightTwo and SpaceShipTwo aircraft will be doing the world a favor when they start flying paying passengers into space: they’ll be carrying sensors aboard to monitor greenhouse gases at a little-monitored altitude. The National Oceanic and Atmospheric Administration has just signed a deal with Virgin to let it install sensors on the two vehicles, since it turns out that they will be one of the few aircraft that fly at around 50,000 feet. Most aircraft, with the exception of the sadly gone Concorde, fly below this altitude, and scientists would like to get their hands on air data from this height to help with environmental monitoring.
