Genetically modified organisms have existed for thousands of years but more recently an anti-science contingent has been concerned, perhaps with reason, about their impact on the environment.
But genetically modified organisms, like forests of genetically altered trees and other plants, could also help save the environment and sequester several billion tons of carbon from the atmosphere each year, according to a study in BioScience.
HOUSTON -- (Sept. 29, 2010) -- A Rice University-led team of physicists is reporting the first success in a three-year effort to build a precision simulator for superconductors using a grid of intersecting laser beams and ultracold atomic gas.
New Haven, Conn.—The rules that govern the world of the very small, quantum mechanics, are known for being bizarre. One of the strangest tenets is something called quantum entanglement, in which two or more objects (such as particles of light, called photons) become inextricably linked, so that measuring certain properties of one object reveals information about the other(s), even if they are separated by thousands of miles. Einstein found the consequences of entanglement so unpalatable he famously dubbed it "spooky action at a distance."
A global temperature increase of up to 4.2 º C and the end of coral reefs could become reality by 2100 if national targets are not revised in the Copenhagen Accord, the international pledge which was agreed at last year's Copenhagen's COP15 climate change conference.
Scientists from the Institute of Tropical Medicine Antwerp, in collaboration with colleagues from several developing countries, were able to restore a sleeping sickness parasite's susceptibility to drugs. The parasite causes sleeping sickness in cattle. Because it has become resistant against all currently available drugs, it causes enormous economic losses. Until now, that is.
Washington, D.C. (September 28, 2010) -- Polymer-based photovoltaic cells have some real advantages compared to the currently used semiconductor-based cells. They are easy to make and the materials are cheap. The challenge is to figure out how to make efficient cells while keeping the manufacturing cost low.
Whither pandemic H1N1 virus? In a new commentary, scientists from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, review the fates of previous pandemic influenza viruses in the years following a pandemic and speculate on possible future courses for the 2009 pandemic H1N1 (pH1N1) virus during the upcoming flu season and beyond.
When the scientific and spiritual worlds collide, they do so in the most surprising ways. Classical meteorological and plant science has, in the last century, insisted that dew negatively affects plant life, leading to rot and fungus. But in the Judeo-Christian tradition, dew is most welcomed as an important source of vegetative and plant life, celebrated in poetry and prayer.
HOUSTON, Sept. 28, 2010 – A large section of northwestern Harris County – particularly the Jersey Village area – is sinking rapidly, according to a University of Houston (UH) geologist who has analyzed GPS data measuring ground elevation in the Houston area.
DURHAM, N.C. – Duke University bioengineers have not only figured out a way to sneak molecular spies through the walls of individual cells, they can now slip them into the command center -- or nucleus -- of those cells, where they can report back important information or drop off payloads.
Researchers in the field of bioballistics – how plants, fungi and animals accelerate seeds, spores or even parts of their body to high speed – have found an amazing variety of techniques to overcome friction with the air, the main limitation for small spores and seeds.
Rice University physicist Dmitri Lapotko has demonstrated that plasmonic nanobubbles, generated around gold nanoparticles with a laser pulse, can detect and destroy cancer cells in vivo by creating tiny, shiny vapor bubbles that reveal the cells and selectively explode them.
A paper in the October print edition of the journal Biomaterials details the effect of plasmonic nanobubble theranostics on zebra fish implanted with live human prostate cancer cells, demonstrating the guided ablation of cancer cells in a living organism without damaging the host.
Entanglement is a fascinating property connecting quantum systems. Albert Einstein called it the "spooky action at a distance". This bizarre coupling can link particles, even if they are located on opposite sides of the galaxy. The strength of their connections is behind the promising quantum computers, the dream machines capable of quick and efficient computations.
