VR makes journalism immersive, realism makes it credible

VR makes journalism immersive, realism makes it credible
  Virtual reality technology may help journalists pull an audience into their stories, but they should avoid being too flashy, or their credibility could suffer, according to a team of researchers.

Chip-based sensors have outstanding sensitivity

Chip-based sensors have outstanding sensitivity
In London's St. Paul's Cathedral, a whisper can be heard far across the circular whispering gallery as the sound curves around the walls. Now, an optical whispering gallery mode resonator developed by Penn State electrical engineers can spin light around the circumference of a tiny sphere millions of times, creating an ultrasensitive microchip-based sensor for multiple applications.

Piezoelectrics stretch their potential

Piezoelectrics stretch their potential
  Piezoelectric materials are used for applications ranging from the spark igniter in barbeque grills to the transducers needed by medical ultrasound imaging. Thin-film piezoelectrics, with dimensions on the scale of micrometers or smaller, offer potential for new applications where smaller dimensions or a lower voltage operation are required.

Plant-based sensors alert when crops need to be watered

Plant-based sensors alert when crops need to be watered
  Plant-based sensors that measure the thickness and electrical capacitance of leaves show great promise for telling farmers when to activate their irrigation systems, preventing both water waste and parched plants, according to researchers in Penn State's College of Agricultural Sciences.

Materials breakthrough will supercharge wide-bandgap semiconductors

Materials breakthrough will supercharge wide-bandgap semiconductors
  In a significant breakthrough, materials scientists at Pennsylvania State University have synthesized two-dimensional gallium nitride for the first time ever using a graphene encapsulation said to give the structure 'superb electronic properties and strength to the resulting flat gallium nitride'.

Harnessing the power of photosynthesis

Harnessing the power of photosynthesis
  Identification of a gene needed to expand light harvesting in photosynthesis into the far-red-light spectrum provides clues to the development of oxygen-producing photosynthesis, an evolutionary advance that changed the history of life on Earth.

3D printing creates cartilage patches from bioink

3D printing creates cartilage patches from bioink
Strands of cow cartilage substitute for ink in a 3D bioprinting process that may one day create cartilage patches for worn out joints, according to a team of engineers. "Our goal is to create tissue that can be used to replace large amounts of worn out tissue or design patches," said Ibrahim T. Ozbolat, associate professor of engineering science and mechanics. "Those who have osteoarthritis in their joints suffer a lot. We need a new alternative treatment for this."

Penn State to lead next-gen planet finder

Penn State to lead next-gen planet finder
A Penn State-led research group has been selected by NASA's Astrophysics Division to build a $10-million, cutting-edge instrument to detect planets orbiting stars outside our solar system. The team, led by Suvrath Mahadevan, assistant professor of astronomy and astrophysics at Penn State University, was selected after an intense national competition.

Microfluidic devices rotate small organisms and cells

Microfluidic devices rotate small organisms and cells
A method to rotate single particles, cells or organisms using acoustic waves in a microfluidic device will allow researchers to take three dimensional images with only a cell phone. Acoustic waves can move and position biological specimens along the x, y and z axes, but for the first time researchers at Penn State have used them to gently and safely rotate samples, a crucial capability in single-cell analysis, drug discovery and organism studies.

Movie machines may boost robot acceptance

Remembering robots from film portrayals may help ease some of the anxiety that older adults have about using a robot, according to Penn State researchers. In a study, older adults who recalled more robots portrayed in films had lower anxiety toward robots than seniors who remembered fewer robot portrayals, said S. Shyam Sundar, Distinguished Professor of Communications and co-director, Media Effects Research Laboratory.

New material reduces the cost of smartphones

New material reduces the cost of smartphones
When it comes to smartphones, tablet computers and television displays, one construction material dominates them all: Indium tin oxide (ITO). It has been used for the last 60 years, and is a key component for more than 90 percent of all such displays. But a potential competitor to ITO has just been discovered, one that is both highly transparent and extremely conductive. Its workings are detailed in the journal Nature Materials.
