Daniel Hillel developed a system called micro-irrigation, which has opened up dry regions to farming, revolutionizing agriculture worldwide. The Israeli scientist has worked closely with Arab friends in Jordan, Egypt, and the United Arab Emirates.
New groundbreaking research by scientists at Trinity College Dublin has found that exposure to nanoparticles can have a serious impact on health, linking it to rheumatoid arthritis and the development of other serious autoimmune diseases. The findings that have been recently published in the international journal Nanomedicine have health and safety implications for the manufacture,…
A Kentucky museum where dinosaurs roam the biblical Garden of Eden is unveiling a national billboard campaign featuring the popular prehistoric reptiles. The cartoon billboards are appearing in several cities including Chicago, San Francisco and Houston and feature colorful dinosaurs drawn in a vintage comic book style. The signs are a new ad campaign for…
The final round of negotiations leading up to next week’s Rio+20 summit begins with countries very much at odds on key issues. The draft agreement would improve energy, water and food security in poorer countries, phase out fossil fuel subsidies and boost ocean protection. But with three days of negotiations left, only 20% has been…
Physicists investigating the make-up of the universe are closing in on the Higgs boson, an elusive particle thought to have been key to turning debris from the Big Bang into stars, planets and finally life, scientists said. Researchers at the European Organization for Nuclear Research (CERN) are using their large Hadron Collider (LHC), the world’s…
The balance of nature and nurture in influencing how a child grows up varies depending on where they live, according to a new study.
It’s clear touch and emotion can be closely tied: The brush of a hand can provoke excitement, comfort or repulsion — all depending on who’s delivering the touch and when. But new research indicates the emotional connection shows up early as the brain processes a social touch. Using brain scans to monitor responses from heterosexual…
Better lithium ion batteries have led to an explosion in availability of plug-in passenger cars. And now, thanks to relatively cheap electricity and the simplicity of the electric drivetrain, electric vehicles have even more potential for use in the extremely cost-sensitive public transportation arena—a concept that is only just taking root. In particular, two projects…
Smooth wrinkles and sharply crumpled regions are familiar motifs in biological and synthetic sheets, such as plant leaves and crushed foils, say physicists Benny Davidovitch, Narayanan Menon and colleagues at the University of Massachusetts Amherst, but how a featureless sheet develops a complex shape has long remained elusive. Now, in a cover story of the…
“Prometheus,” the new movie from the director Ridley Scott, is a scientific and spiritual quest. The scientists in the movie think somebody or something else created us. Creationism? Yes, in a way, but creationism for geeks, of the sort that science fiction writers and scientists have long indulged in. It does not run counter to…
