Flu Wiki, “dedicated to sharing accurate information without scaremongering,” includes links to CDC, WHO, and other key sources.
Jimmy Wales: “I need help. Please edit with calm facts — our response to media panic!”
Using a new electrically-assisted microbial fuel cell (MFC) that does not require oxygen, researchers at Penn State and Ion Power Inc. have developed the first process that enables bacteria to coax four times as much hydrogen directly out of biomass than can be generated typically by fermentation alone.
“This form of renewable energy production may help offset the substantial costs of wastewater treatment as well as provide a contribution… read more
Max Planck researchers have found that transparent electrodes created from graphene could make solar cells and LCDs without depleting indium resources.
Experts calculate that there is only 10 years’ worth of indium left on the planet, with LCD panels consuming the majority of existing stocks.
The Max Planck team has produced electrodes just 10 graphene layers thick, or roughly five nanometers. These have a transparency of about 80… read more
Rez, a new PlayStation 2 video game, aims to overload the senses with its psychedelic visuals and pulsating dance beats to create a sense of synesthesia.
The game takes place in a virtual world inside a computer. You play a hacker, flying through six levels of cyberspace in search of the AI at the center. Destroying one of the insect-like enemies causes synchronized music and images to be generated.
Fujitsu has developed has developed the world’s fastest (128 Gigabits/sec.) supercomputer CPU prototype, beating the current record, held by Intel Corp., by 2.5 times.
Rice University scientists have found that buckyballs dissolve in water and could have a negative impact on soil bacteria. The findings raise new questions about how the nanoparticles might behave in the environment and how they should be regulated.
The found that buckyballs combine into unusual nano-sized clumps — which they refer to as “nano-C60″ — that are about 10 orders of magnitude more soluble in water than the… read more
Arguments that black holes do not exist and quantum mechanics research that finds an observer can change the behavior of light, even after it has been measured, are two of Science Now’s top stories of 2007.
The sharpest images ever achieved by optical means have been produced by researchers at the Max Planck Institute for Biophysical Chemistry, who have imaged clumps of bacteria just 33 nanometres across, equivalent to 1/23 of the wavelength of light used to illuminate them.
The researchers hope to achieve a resolution of around 17 nanometres, using ultraviolet light. Practical devices are expected within two or three years, which could have microlithography… read more
Eyenovations has developed contact lenses that can deliver drugs to the eye for a month or more, using a hydrogel lens with a polymer film inside that contains the medication.
Uses include delivery of medicine without relying on frequent eyedrops for patients with glaucoma and for delivering antibiotics following eye surgery.
A new hydrogen-powered fuel cell technology for portable devices is reportedly safe and longer-lasting than today’s batteries.
The new technology stores fuel in the form of the stable and non-explosive sodium borohydride solution, converting it to hydrogen as needed.
The first large-scale study of “cellulosic” perennial crop-based fuels shows that switchgrass yields more than five times the energy needed to grow, harvest, and transport the grass and convert it to ethanol.
U.S. Department of Agriculture researchers also found that the switchgrass is carbon-neutral, since it absorbs essentially the same amount of greenhouse gases while it’s growing as it emits when burned as fuel.
We are about to supersede evolution by direct intervention in the genetic process, argues Francis Fukuyama in “Our Posthuman Future,” which discusses cloning, germ-line genetic engineering, stem cell research, neuropharmacology, anti-aging medicine, and the potential for violations of human nature from the new biotechnology.
Molecules taking part in photosynthesis can remain entangled even at ordinary atmospheric temperatures, Berkeley, California researchers have found, suggesting the possibility of photosynthetic quantum computers.
Does this support the Hameroff/Penrose idea of quantum computation in brain microtubules as a model of consciousness? – Ed.
U.S. residents are so hooked on e-mail that some check for messages in the bathroom, in church and while driving, a new survey sponsored by America Online Inc. has found.
About a fourth of respondents acknowledged being so addicted to e-mail that they can’t go more than two or three days without checking for messages. That includes vacations, during which 60% of respondents admitted logging into their in-boxes.
