On invasive species, Darwin had it right all along, study shows

Dov Sax of Brown University and Jason Fridley of Syracuse University aren't proposing a novel idea to explain species invasiveness. In fact, Charles Darwin articulated it first. What's new about Sax and Fridley's "Evolutionary Imbalance Hypothesis" (EIH) is that they've tested it using quantifiable evidence and report in Global Ecology and Biogeography that the EIH works well.…

Geneticists solve 40-year-old dilemma to explain why duplicate genes remain in the genome

Geneticists at Trinity College Dublin have made a major breakthrough with important implications for understanding the evolution of genomes in a variety of organisms. They found a mechanism sought for more than four decades that explains how gene duplication leads to novel functions in individuals. Gene duplication is a biological phenomenon that leads to the…

Complex organic molecule found in interstellar space

Scientists have found the beginnings of life-bearing chemistry at the centre of the galaxy. Iso-propyl cyanide has been detected in a star-forming cloud 27,000 light-years from Earth. Its branched carbon structure is closer to the complex organic molecules of life than any previous finding from interstellar space. The discovery suggests the building blocks of life…

Fossil of ancient multicellular life sets evolutionary timeline back 60 million years

A Virginia Tech geobiologist with collaborators from the Chinese Academy of Sciences have found evidence in the fossil record that complex multicellularity appeared in living things about 600 million years ago -- nearly 60 million years before skeletal animals appeared during a huge growth spurt of new life on Earth known as the Cambrian…

Researchers create ‘evolved’ protein that may stop cancer from spreading

A team of Stanford University researchers has developed a protein therapy that in mice was able to disrupt the process that causes cancer cells to break away from original tumor sites, travel through the bloodstream and start aggressive, new growths elsewhere in the body. This process, known as metastasis, can cause cancer to spread with…

WHAT’S POSSIBLE: The U.N. Climate Summit Film (Preview)

Presented to world leaders at the United Nations Climate Summit in New York, this short inspirational film shows that climate change is solvable. We have the technology to harness nature sustainably for a clean, prosperous energy future, but only if we act now. Narrated by Morgan Freeman, it calls on the people of the…

Clean the Everglades, win $10 million

The rise of the prize has helped define innovation in the 21st Century, triggering breakthroughs in space travel, third-world vaccinations, driver-less cars and even better movie downloads. Now the Everglades Foundation has joined the trend with its own science challenge: $10 million to anyone who can solve the chronic problem of phosphorous pollution that has…

MinION USB stick gene sequencer finally comes to market

When it comes to DNA, France has always been behind the times. Never mind the hefty fines and prison sentence a man apparently can get for trying to order a paternity test, it seems that just knowing your own genetic sequence is offensive enough. Now that the much anticipated MinION USB stick genome sequencer has finally…

‘Artificial spleen’ could help treat sepsis

Its victims include the actor Christopher Reeve, Pope John Paul II, and the British poet Rupert Brooke, who died after a mosquito bite on his lip became infected. Sepsis remains one of the leading killers in the United States and the world. Now, researchers describe a novel way to treat the lethal condition by filtering…

Counting fish teeth reveals regulatory DNA changes behind rapid evolution, adaptation

Sticklebacks, the roaches of the fish world, are the ideal animal in which to study the genes that control body shape. They've moved from the ocean into tens of thousands of freshwater streams and lakes around the world, each time changing their skeleton to adapt to the new environment. Breeding studies between marine and freshwater…
