Scientists developing genetically modified wheat are asking campaigners not to ruin their experimental plots, but come in for a chat instead. The trial at Rothamsted Research in Harpenden, Herts, uses wheat modified to deter aphids, an insect pest. The protest group Take the Flour Back has vowed to "decontaminate" the site unless the research is halted. The scientists say the GM plants could benefit the environment as they will reduce pesticide use. "We appeal to you as environmentalists," they write in an open letter. "Our GM wheat could, for future generations, substantially reduce the use of agricultural chemicals." But the campaigners say the GM trial ...

Wind farms can cause climate change, according to new research, that shows for the first time the new technology is already pushing up temperatures. Wind farms can cause a rise in temperature, found a study in Nature. Usually at night the air closer to the ground becomes colder when the sun goes down and the earth cools. But on huge wind farms the motion of the turbines mixes the air higher in the atmosphere that is warmer, pushing up the overall temperature. Satellite data over a large area in Texas, that is now covered by four of the world's largest wind farms, found that over a decade the local temperature went up by almost 1C as more turbines are built. This could have ...

In the first half of Monday's show, author Dr. Jerome Corsi discussed how Nazi chemists developed a series of equations during WWII which demonstrated that oil can be formed synthetically. Known as the Fischer-Tropsch equations, they indicated that the mixture of hydrogen and carbon with various catalysts under intense pressure and heat, produced hydrocarbons-- such as what is made in the mantle of the Earth on an ongoing basis, he explained. It doesn't take dead plants or animals, dinosaurs, plankton, algae or former living matter to produce oil, and the Nazis understood this, he continued, adding that some of their scientists were brought over to the US during Operation Paperclip ...

Filling in for George Noory, John B. Wells was joined for the entire program by British astronomer Dr. David Darling for a discussion about some strange ways our world could be brought to a 'megacatastrophic' end. According to Darling, a likely population-ending scenario involves a biological pandemic, something similar to the Plague. "There's a real problem that [a virus or bacteria] is going to develop total drug resistance... and be highly infectious as well," he said. Darling estimated that a highly-virulent, untreatable infection could wipe out half of the people on the planet in weeks. Darling reported on a possible nanotechnological nightmare known as the ...

New research at Concordia University is bringing us one step closer to clean energy. It is possible to extend the length of time a battery-like enzyme can store energy from seconds to hours, a study published in the Journal of The American Chemical Society shows. Concordia Associate Professor László Kálmán -- along with his colleagues in the Department of Physics, graduate students Sasmit Deshmukh and Kai Tang -- has been working with an enzyme found in bacteria that is crucial for capturing solar energy. Light induces a charge separation in the enzyme, causing one end to become negatively charged and the other positively charged, much like in a battery. In ...

Cancerous cells Breast cancer cells should be classified into one of 10 different diseases, say researchers. What we currently call breast cancer should be thought of as 10 completely separate diseases, according to an international study which has been described as a "landmark". The categories could improve treatment by tailoring drugs for a patient's exact type of breast cancer and help predict survival more accurately. The study in Nature analysed breast cancers from 2,000 women. It will take at least three years for the findings to be used in hospitals. Cancer cartography Researchers compared breast cancer to a map of the world. They said tests currently used in ...

"XNA" may help answer basic questions of biology, study says. The work of DNA strands (shown in a computer model) can be done in part by new polymers. Step aside, DNA—new synthetic compounds called XNAs can also store and copy genetic information, a new study says. And, in a "big advancement," these artificial compounds can also be made to evolve in the lab, according to study co-author John Chaput of the Biodesign Institute at Arizona State University. (See "Evolution vs. Intelligent Design: 6 Bones of Contention.") Nucleotides, the building blocks of DNA are composed of four bases—A, G, C, and T. Attached to the bases are sugars and phosphates. ...

ScienceDaily (Apr. 13, 2012) — Scientists at TU Delft's Kavli Institute and the Foundation for Fundamental Research on Matter (FOM Foundation) have succeeded for the first time in detecting a Majorana particle. In the 1930s, the brilliant Italian physicist Ettore Majorana deduced from quantum theory the possibility of the existence of a very special particle, a particle that is its own anti-particle: the Majorana fermion. That 'Majorana' would be right on the border between matter and anti-matter. Nanoscientist Leo Kouwenhoven already caused great excitement among scientists in February by presenting the preliminary results at a scientific congress. Today, the scientists ...

Zoos want to import polar bears to save the species By — Juliet Eilperin, Published: April 9 Polar bears are perfectly suited to life in the Arctic: Their hair blends in with the snow; their heavy, strongly curved claws allow them to climb over blocks of ice and snow and grip their prey securely; and the rough pads on their feet keep them from slipping. The one thing they cannot survive is the loss of the ice, and the changes in worldwide climate threaten to melt the summer sea ice on which they hunt. Scientists say two-thirds of the world’s polar bears could disappear by about 2050. So a group of American zoo and aquarium officials are asking the federal government to let ...
