Infrared Brings to Light Nanoscale Molecular Arrangement

Detailing the molecular makeup of materials – from solar cells to organic LEDs and transistors to medically important proteins – is not always a crystal-clear process. To understand how materials work at these microscopic scales and to better design materials to improve their function, it's necessary to know not only about their composition but also their molecular arrangement and microscopic imperfections.

New Catheter Lets Doctors See Inside Arteries

Removing plaque from clogged arteries is a common procedure that can save and improve lives. This treatment approach has been made safer and more effective with a high-tech catheter that allows cardiologists to see inside arteries for the first time, cutting out only the diseased tissue. Interventional cardiologists at Sulpizio Cardiovascular Center at UC San Diego Health are the first in the region to use this technology.

Mapping Marine Snow on Sea Floor

City-sized maps of terrain and life on the sea floor have revealed that drifts of "marine snow" on submarine hillsides act as a source of food to fuel a higher biomass of marine life than on flatter plains. This finding comes from research by scientists at the National Oceanography Centre (NOC) that may improve understanding of how hillside slopes and plateaus drive the distribution of marine life. The marine snow was quantified using machine vision, where an algorithm automatically detected the location and coverage in digital images.

Will virtual reality increase empathy?

This week's Question: According to a recent article in The Washington Post, a growing number of filmmakers, policymakers, researchers, human rights workers, and law enforcement officials are using virtual reality technology to make people feel as if they have experienced an event firsthand. Advocates say virtual reality can increase empathy, "transport" and immerse viewers within humanitarian crises around the world, and influence decision-making about issues ranging from policing to the environment. What do you think? Will virtual reality increase empathy?

Combating Driver Fatigue with Mobile Surveillance

Driver fatigue is a leading cause of traffic accidents for heavy-duty vehicles such as mining trucks, excavators, bulldozers, cranes, cargo trucks, and buses. Their drivers need a rapid alert system to keep them awake and on the road. Find out about an in-vehicle surveillance platform that uses a camera to monitor drivers for fatigue, analyzing video in real-time to activate alerts and wireless communications.

Inside NASA’s White Sands Test Facility: How High-Speed Cameras Support Hypervelocity Experiments

At NASA’s White Sands Test Facility, Donald Henderson and his team spend much of their days shooting projectiles at 15,700 miles per hour. Hypervelocity testing done at the Las Cruces, NM center simulates the impact of micrometeoroids and orbital debris on spacecraft shields.

Spectroscopy System

Princeton Instruments (Trenton, NJ) launched the FERGIE ™ spectroscopy system, a fully integrated, aberration-free spectrograph with a built-in, low-noise, cooled detector in an 11 × 7 × 8" profile. Thanks to a proprietary Princeton Instruments optical design, FERGIE offers spectral resolution of 0.13 nm/pixel with a 1200 g/mm grating. Additionally, FERGIE’s diffraction-limited imaging (>60 lp/mm spatial resolution throughout the focal plane) yields exceptionally high signal-to-noise ratios and permits multichannel spectroscopy.
