Hind wings help butterflies make swift turns to evade predators, study finds
New tires allow race cars to take tight turns at high speeds. Hind wings give moths and butterflies similar advantages: They are not necessary for basic flight but help these...
New Power Line De-icing System Developed
Engineers have invented a way to cheaply and effectively keep ice off power lines. The new proprietary technology is called a variable resistance cable (VRC) de-icing system. With only minor...
Heavy pyridine crystallises differently
The nuclei of ordinary hydrogen atoms contain only a single proton. If a neutron is added, the hydrogen becomes deuterium. In principle, molecules that contain deuterium in place of hydrogen...
Spookfish uses mirrors for eyes
A remarkable new discovery shows the four-eyed spookfish to be the first vertebrate ever found to use mirrors, rather than lenses, to focus light in its eyes. read more
Anti-Casimir force spotted by Harvard researchers
For the first time, researchers have measured a long-theorized force that operates at distances so tiny they’re measured in billionths of a meter, which may have important applications in nanotechnology...
New technique 'banks' wind farm energy
MILWAUKEE, Jan. 8 (UPI) -- A high-tech way of "banking" extra energy from high winds can improve wind power's ups and downs and make it more efficient, U.S....
Sandisk Unleashes World's Fastest MLC SSD Family
SanDisk Corporation today unveiled its third-generation family of solid-state drives (SSDs). Using multi-level cell (MLC) NAND flash memory technology, SanDisk`s G3 Series establishes new benchmarks in performance and price-performance leadership...
U.S. scientists learn how to levitate tiny objects
Scientists have found a way to levitate the very smallest objects using the strange forces of quantum mechanics, and said they might use it to help make tiny nanotechnology machines.
The Minimalist: Fresh Start for a New Year? Let’s Begin in the Kitchen
While stocking up on ingredients to help you cook quickly, you might clear out a bit of the detritus that’s cluttering your shelves.
SlotPhones combine a headset with a MP3 player
(AP) -- A new model of headphones can play MP3s themselves, without connecting to a separate device.
Opinion: Ethanol as a biofuel - immoral, costly and stupid
Ron Leng wonders whether limiting the unnecessary use of 4WDs would be more efficient than pumping taxpayers' money into a fuel that takes more energy to create than it can...
MOF Housekeeping Improves
Supercritical CO2 scrubs porous metal-organic frameworks, increasing surface area for applications
Scientists Propose Thermal Memory to Store Data
Most computers today store memory electronically, by maintaining a certain voltage. In contrast, a new kind of memory that stores data thermally, by maintaining temperature, is being investigated by researchers...
Toronto directors get 2nd prize in YouTube short film contest
Two Toronto filmmakers have captured second prize in the YouTube Project:Direct contest, garnering them a ticket to the Sundance Film Festival. The $2,500 US prize was handed to Jason Gossbee...
A Conversation with Len Fisher
Chances are you've played Rock, Paper, Scissors, but how do you calculate your strategy, if you have one at all? In Rock, Paper, Scissors: Game Theory in Everyday Life, physicist Len...
Reducing Pollution From Textile Industry: Glucose Facilitates Use Of Natural Indigo
Glucose can serve as a reducing agent of indigo. This finding is significant for devising more ecological dyeing practices for the textile industry.
3T MRI can detect wrist ligament tears, possibly eliminating need for invasive arthroscopy
MRI of the wrist at 3T is an effective way to detect wrist ligament tears and in some cases can avoid unnecessary surgery, according to a study performed at Neuroskeletal...
Physicists squeeze light to quantum limit
A team of University of Toronto physicists have demonstrated a new technique to squeeze light to the fundamental quantum limit, a finding that has potential applications for high-precision measurement, next-generation...

Scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory have successfully stopped and then reaccelerated a stable ion through a newly constructed charge-breeder, bringing the CAlifornium Rare Isotope...
Researchers construct a device that mimics one of nature's key transport machines
(PhysOrg.com) -- To help protect its genes, a cell is highly selective about what it allows to move in and out of its nucleus. Yet that choosiness is regulated by...
New hydrogen production method could reduce need for fossil fuels
(PhysOrg.com) -- Scientists have created an entirely natural and renewable method for producing hydrogen to generate electricity which could drastically reduce the dependency on fossil fuels in the future.
