Perfectly proportioned
It all happens very quickly: the feed shoe, configured as an open-bottomed box, moves across a surface in which a recess forms the shape of the desired part. The fine-grained...
Capturing Those In-between Moments: Timing Problem In Molecular Modeling Solved
A theoretical physicist has developed a method for calculating the motions and forces of thousands of atoms simultaneously over a wider range of time scales than previously possible. The method...
Micro-injector could speed drug development
Engineers at McMaster University in Hamilton have built a palm-sized device that can automatically inject proteins or drugs into a series of individual cells like an assembly line.
Study Proves That Specialized Prosthetic Legs Grant No Advantage In Sprinting
In 2008, the International Association of Athletics Federations (IAAF) banned double amputee Oscar Pistorius from racing in the 2008 Summer Olympics. Later that same year, the ban was reversed. The back and forth...
Toward Home-brewed Electricity with "Personalized Solar Energy"
New scientific discoveries are moving society toward the era of "personalized solar energy," in which the focus of electricity production shifts from huge central generating stations to individuals in their...
NIST Test Proves 'The Eyes Have It' for ID Verification
The eyes may be the mirror to the soul, but the iris reveals a person's true identity. A new report from NIST demonstrates that iris recognition algorithms can maintain their...
Learn To Compute Higgs Limits On The Fly
I am presently into the second week of my lessons of Subnuclear Physics for the 2nd year of specialization in Physics, and I have just finished a lesson discussing the...
Space Hotel Takes Reservations for 2012 Opening
Some forward-looking vacationers have already booked a stay at the first space hotel, which is on track to open in 2012, according to the owners of the planned orbital resort.
Tiny Thermoelectric Loudspeaker Produces Audio By Tweaking Temperature
A standard home audio speaker converts electrical signals into sound pulses in the air (via a somewhat cumbersome cone). Those sound waves in turn cause tiny variations in air temperature, as waves disrupt...
Bolivia plans to lead the electric revolution
Bolivia is to go it alone and start mining its lithium reserves – a move that will aid electric car production
Hybrid Composite For Root Canal Treatment
A dentist carrying out root canal treatment will need to use a variety of compounds. These do not always bond together properly and sometimes expensive follow-up treatment has to be...
Light down a wire for solar power
A modification to commercial optical fibre could be a promising route to solar power without large arrays, say researchers.
Clean algae biofuel project leads world in productivity
Australian scientists are achieving the world's best production rates of oil from algae grown in open saline ponds, taking them a step closer to creating commercial quantities of clean biofuel...
Bloodhound engineers test-fire rocket for supersonic car
A team of British engineers have fired up the rocket that they hope will propel their car to speeds in excess of 1,000mph, smashing the land speed record. Rocket scientist Daniel Jubb...
Approaches to Photovoltaic Systems Reliability to be Presented at ISTFA Event in San Jose
To tackle the challenge of systems reliability for alternative energy, a special session will be held during the 35th International Symposium for Testing and Failure Analysis (ISTFA), coming Nov. 15-19...
UCLA researchers reconstitute enzyme that synthesises cholesterol drug lovastatin
Researchers from the UCLA Henry Samueli School of Engineering and Applied Science have for the first time successfully reconstituted in the laboratory the enzyme responsible for producing the blockbuster cholesterol-lowering...
New methods found useful for diagnosing myocarditis
Myocarditis is an important, and often unrecognised cause of dilated cardiomyopathy (DCM). Several new diagnostic methods, such as cardiac magnetic resonance imaging (MRI), are useful for diagnosing myocarditis, according to...
K-State engineers strive to make algae oil production more feasible
Two Kansas State University engineers are assessing systematic production methods that could make the costs of algae oil production more reasonable, helping move the U.S. from fossil fuel dependency to...
X-rays 'top scientific invention'
The public votes the x-ray machine as the best invention over the Apollo 10 space capsule and Stephenson's rocket.
Oxygen Exchangers Increase Propene Yield
A Dutch researcher has shown that the yield of propene can be increased by adding cerium oxide during the production process. Propene is an important raw material for the chemical...
Short Heels Make Elite Sprinters Super Speedy: Longer Toes, Unique Ankle Structure Aid Sprinters
Longer toes and a unique ankle structure provide sprinters with the burst of acceleration that separates them from other runners, according to biomechanists.
Liquid Granite: Building Material Of The Future Unveiled
Scientists have developed a new building material that is fire resistant to temperatures in excess of 1100 degrees Celsius, is made largely from recycled material and is as versatile as...
Compressing photonic signals for greater bandwidth
Cornell researchers have developed an ingenious method to time-compress optical signals. The process could enable optical communication systems to carry many more bits per second or could also be used...
Silk-Silicon Implantable Electronics Conform to Tissues, Then Melt Away
Implantable electronics like pacemakers are old hat, but these kinds of implants are limited by the fact that they must be encased to protect them from the body, and vice versa. But...
Car That Runs on Compressed Air Questioned by Critics (w/ Video)
(PhysOrg.com) -- As electric cars begin breaking into the short-distance vehicle market, one French company thinks that it has an alternative to the electric vehicle: a car that runs on...
