Small sample sizes, poor study design, researcher bias, and selective reporting and other problems with experimental and statistical methods mean that there is less than a 50% chance that the results of any randomly chosen scientific paper are true.
MIT scientists have developed a unique polymer coating made of silica nanoparticles that they say can create surfaces that never fog.
The coatings consist of alternating layers of silica nanoparticles and a polymer called polyallylamine hydrochloride. The super-hydrophilic nanoparticles in the coating strongly attract the water droplets and force them to form much smaller contact angles with the surface. As a result, the droplets flatten and merge into a… read more
Cornell University researchers have made DNA buckyballs that could be used for drug delivery and as containers for chemical reactions.
The buckyballs are made from a specially prepared, branched DNA-polystyrene hybrid. The hybrid molecules spontaneously self-assemble into hollow balls about 400 nanometers in diameter.

WinHoldEm, the first commercially available autoplaying poker software, wins real money while you sleep.
Lightning guns, heat rays, weapons that can make you hear the voice of God. This is what happens when the war on terror meets the entrepreneurial spirit.
The National Science Foundation’s Global Environment for Networking Investigations project is intended to fundamentally re-engineer the Internet and overcome its shortcomings.
The network will focus on security, “pervasive computing” environments populated by mobile, wireless and sensor networks, control of critical infrastructure and the ability to handle new services that can be used by millions of people.
Scientists are looking at using the highly conductive properties of carbon nanotubes to dissipate heat from computer chips, which would allow them to run faster without overheating.
Researchers have dramatically increased the life spans of mice by up to 30 percent by genetically engineering them to overproduce a protein called klotho.
The gene regulates production of klotho protein, which the study team says works like an anti-aging hormone. Kotho is involved in the suppression of insulin-signaling pathways — a process that has been shown to increase the life spans of worms and flies.
Using an advanced speech-recognition/voice response chip, an electronic memory, and facial motors, Amazing Amanda, scheduled for release next month by Playmates Toys, will “listen, speak and show emotion,” with responses customized to the individual child.
MIT researchers have developed a technique that prints DNA from one substrate — for example glass, gold or silicon — onto another. Using a print template, they can produce mirror-image copies in just a simple few steps, offering the rapid transfer of a large amount of information and allow for low-cost DNA analysis.
The technique, called “supramolecular nano-stamping” (SuNS), could be used to produce many other kinds of nano-devices:… read more
Diamond slivers only nanometers wide could serve as atomic-force microscope tips that help print advanced circuitry, for DNA sequencing devices, or for conductivity measurements of neurons to examine synapses and signal mechanisms.
A common problem atomic-force microscopes face is how their cantilever tips break down as they run over surfaces. Researchers at Northwestern University and Argonne National Laboratory have invented probes made of what they call ultra nanocrystalline diamond.… read more
Hitachi on Wednesday unveiled the world’s first hard disk drive/DVD recorder that can store one terabyte of data, or enough to record about 128 hours of high-definition digital broadcasting.
InPhase Technologies is developing one of the first commercial systems to use “holographic storage,” using a disc with more than 60 times the storage capacity of a standard DVD, while the drive writes about 10 times faster than a conventional DVD burner. That means the disc can store up to 128 hours of video content.
Every major cable company is making investments to allow TV to be distributed over the Internet, giving you access to 31 million hours pf programming per year. And then there’s this year’s 36-fold explosion in consumer-generated video on the Internet.
Yahoo! is working with SBC and Microsoft on an IPTV/fiber-to-the-curb initiative called Project Lightspeed that uses Yahoo! software to deliver video-on-demand, instant messaging, photo collections, and music.
