Hubble eyes a mysterious old spiral

Posted: 26 Jul 2013 10:58 AM PDT

A striking cosmic whirl is the center of galaxy NGC 524, as seen with the NASA/ESA Hubble Space Telescope. This galaxy is located in the constellation of Pisces, some 90 million light-years from Earth.

Gadget genius: Nanotechnology breakthrough is big deal for electronics

Posted: 26 Jul 2013 09:16 AM PDT

Researchers have developed giant surfactants, or surface coatings, which could lead to lighter laptops, slimmer televisions and crisper smartphone displays.

Removing complexity layers from the universe's creation

Posted: 26 Jul 2013 09:15 AM PDT

Understanding complexity in the early universe may require combining simpler models to interpret cosmological observations. Complicated statistical behavior observed in complex systems such as early universe can often be understood if it is broken down into simpler ones. Physicists have just published results pertaining to theoretical predictions of such cosmological systems' dynamics.

New way to create 'gradients' for understanding molecular interactions

Posted: 26 Jul 2013 07:33 AM PDT

Scientists use tools called gradients to understand how molecules interact in biological systems. Researchers have developed a new technique for creating biomolecular gradients that is both simpler than existing techniques and that creates additional surface characteristics that allow scientists to monitor other aspects of molecular behavior.

Glass scaffolds help heal bone, show promise as weight-bearing implants

Posted: 26 Jul 2013 07:33 AM PDT

Researchers have developed a type of glass implant that could one day be used to repair injured bones in the arms, legs and other areas of the body that are most subject to the stresses of weight.

Gold nanoparticles improve photodetector performance

Posted: 26 Jul 2013 07:33 AM PDT

Using nanoparticles of gold, researchers have found a way to boost the performance of mineral molybdenum disulfide (MoS2), which is found in light-sensing photodetectors used in a wide range of technologies, such as environmental sensing, process control in factories, and optical communication devices.

Quantum of sonics: Bonded, not stirred

Posted: 26 Jul 2013 06:24 AM PDT

Researchers have discovered a new way to join materials together using ultrasound. Ultrasound -- sound so high it cannot be heard -- is normally used to smash particles apart in water. Scientists found that if particles were coated with phosphate, they could instead bond together into strong agglomerates, about the size of grains of sand.

Technology/equipment issues account for almost one in four operating room errors, study finds

Posted: 25 Jul 2013 05:24 PM PDT

Around a quarter of all operating room errors are caused by technology/equipment problems, indicates an analysis of the available evidence.

Physics of running fast: Scientists model 'extraordinary' performance of Bolt

Posted: 25 Jul 2013 05:23 PM PDT

As the world's best athletes descend on London today to take part in the Olympic Anniversary Games, a group of researchers from Mexico has provided an insight into the physics of one of the greatest athletic performances of all time. Researchers have put forward a mathematical model that accurately depicts the extraordinary feats of Usain Bolt during his 100 meter world record sprint at the 2009 World Championships in Berlin.
