Video: NASA Telescope Mirror Tripod in Action

November 26, 2014 | News | Comments

Setting up NASA's James Webb Space Telescope's secondary mirror in space will require special arms that resemble a tripod. NASA recently demonstrated that test in a NASA cleanroom and it was documented in a time-lapse video. The secondary mirror support structure will unfurl in space to about 26.2 feet long once it is deployed.

Single-atom Material Snaps Together like Legos

November 26, 2014 9:50 am | News | Comments

Physicists at the University of Kansas have fabricated an innovative substance from two different atomic sheets that interlock much like Lego toy bricks. The researchers said the new material — made of a layer of graphene and a layer of tungsten disulfide — could be used in solar cells and flexible electronics.


Protons Fuel Graphene Prospects

November 26, 2014 9:28 am | News | Comments

Graphene, impermeable to all gases and liquids, can easily allow protons to pass through it. The discovery could revolutionize fuel cells and other hydrogen-based technologies as they require a barrier that only allow protons – hydrogen atoms stripped off their electrons – to pass through.


Moving Toward Fast, Cheap DNA Sequencing Technology

November 25, 2014 12:00 am | News | Comments

A team of scientists has developed a prototype DNA reader that could make whole genome profiling an everyday practice in medicine. Their goal is to "put cheap, simple and powerful DNA and protein diagnostic devices into every single doctor's office." Such technology could use an individual’s complete DNA and protein profiles to design treatments specific to their individual makeup.


Killing Cancer Cells From Within

November 25, 2014 12:00 am | by Melanie Titanic-Schefft, University of Cincinnati | News | Comments

A nanoparticle designs target and treat early stage cancer cells by killing those cells with heat, delivered from inside the cell itself. Normal cells are thus left unaffected by the treatment regimen. The procedure can ultimately be carried out by the patient themselves after being trained how to direct a small laser light device to the affected area for a specified amount of time two to three times a day.


Cooling With the Coldest Matter in the World

November 25, 2014 12:00 am | News | Comments

Physicists have developed a new cooling technique for mechanical quantum systems. Using an ultracold atomic gas, the vibrations of a membrane were cooled down to less than 1 degree above absolute zero. This technique may enable novel studies of quantum physics and precision measurement devices.


Keeping Unwelcome Guests Out of Cell Nuclei

November 25, 2014 12:00 am | News | Comments

The structure of pores found in cell nuclei has been uncovered, revealing how they selectively block certain molecules from entering, protecting genetic material, and normal cell functions. The discovery could lead to the development of new drugs against viruses that target the cell nucleus and new ways of delivering gene therapies, say the scientists behind the study.


Making Lasers with Graphene

November 24, 2014 4:52 pm | News | Comments

Scientists have studied the dynamics of electrons from the “wonder material” graphene in a magnetic field for the first time. This led to the discovery of a seemingly paradoxical phenomenon in the material. Its understanding could make a new type of laser possible in the future.


Improving Digital Memory Technology

November 24, 2014 4:26 pm | News | Comments

The improvements in random access memory that have driven many advances of the digital age owe much to the innovative application of physics and chemistry at the atomic scale. A team of researchers has employed a Nobel Prize-winning material and common household chemical to enhance the properties of a component primed for the next generation of high-speed, high-capacity RAM.


Chlorine Measurement

Sensorex’s FCL Series free chlorine sensors use amperometric measurement technology to provide accurate monitoring of free chlorine in process applications.


New College Lab Offers Top-level Nanotechnology

November 24, 2014 12:38 pm | by Cate Hansberry, Penn State | News | Comments

Electrical Engineering students at Penn State are receiving their classroom instruction is held in the newly constructed Nanofabrication Laboratory located in the Millennium Science Complex. Undergrads take the class to learn the nanofabrication processes that support silicon integrated circuit technology.


Metamaterial Properties within Hexagonal Boron Nitride

November 24, 2014 12:28 pm | by Daniel Parry, US Naval Research Laboratory | News | Comments

Scientists have demonstrated that confined surface phonon polaritons within hexagonal boron nitride exhibit unique metamaterial properties that enable novel nanoscale optical devices for use in optical communications, super-resolution imaging, and improved infrared cameras and detectors.


Second Time Through, Mars Rover Examines Chosen Rocks

November 24, 2014 12:04 pm | News | Comments

NASA's Curiosity Mars rover has completed a reconnaissance "walkabout" of the first outcrop it reached at the base of the mission's destination mountain and has begun a second pass examining selected rocks in the outcrop in more detail. Exposed layers on the lower portion of Mount Sharp are expected to hold evidence about dramatic changes in the environmental evolution of Mars.


Remote Controlled Nanoparticles Regenerate Bones

November 24, 2014 10:57 am | News | Comments

Researchers in bone tissue regeneration believe they have made a significant breakthrough for sufferers of bone trauma, disease, or defects such as osteoporosis. Medical researchers have found that magnetic nanoparticles coated with targeting proteins can stimulate stem cells to regenerate bone.
