Flexible Electronic Skin Patch Monitors Alcohol Levels

The alcohol sensor consists of a temporary tattoo (left) and a flexible printed electronic circuit board. Engineers at the University of California San Diego have developed a flexible wearable sensor that can accurately measure a person’s blood alcohol level from sweat and transmit the data wirelessly to a laptop, smartphone or other mobile device. The device can be worn on the skin and could be used by doctors and police officers for continuous, non-invasive and real-time monitoring of blood alcohol content.

New NASA Instrument Measures Greenhouse Gases

Mark Stephen (left) and Tony Yu are part of the team that developed the advanced laser system used on the CO2 Sounder Lidar. (NASA's Goddard Space Flight Center/Bill Hrybyk) NASA scientists and engineers have built an instrument powerful and accurate enough to gather around-the-clock global atmospheric carbon-dioxide (CO2) measurements from space. The CO2 Sounder Lidar operates by bouncing an infrared laser light off the Earth’s surface. Like all atmospheric gases, carbon dioxide absorbs light in narrow wavelength bands — in this case, the infrared. By tuning the laser to the infrared, scientists can detect and then analyze the level of carbon dioxide in that vertical path.

Sensors Measure Power Use by Each Device in a Household

Researchers at MIT have developed a device and software that could figure out exactly how much power is being used by every appliance, lighting fixture, and device in a home. (Bryce Vickmark) New postage-stamp-sized sensors developed at MIT measure exactly how much power is being used by every device in a household. No wires need to be disconnected, and the placement of the sensors over the incoming power line does not require any particular precision. The sensors pick up so much information about spikes and patterns in the voltage and current, that the system can tell the difference between every different kind of light, motor, and other device, and show exactly which ones go on and off at what times.

New at IMTS

Optomec (Albuquerque, NM) unveiled its LENS machine tool machines that integrate the company's metal 3D printing technology into standard CNC machine tool platforms. Three standard system configurations are offered, making hybrid and traditional metal additive manufacturing more affordable and accessible. The three systems are open-atmosphere, hybrid additive and subtractive, and an inert system with a hermetically sealed chamber.

Therapeutic Target for Pancreatic Cancer

Pancreatic ductal adenocarcinoma, the most common of pancreatic cancers, is extraordinarily lethal, with a 5-year survival rate of just 6 percent. Chemotherapy treatments are poorly effective, in part due to a high degree of drug-resistance to currently used regimens.

AutoLens Analysis for Euclid Challenge

The European Space Agency's Euclid satellite, due for launch in 2020, will set astronomers a huge challenge: to analyze 100,000 strong gravitational lenses. The gravitational deflection of light from distant astronomical sources by massive galaxies (strong lenses) along the light path can create multiple images of the source that are not just visually stunning but also are valuable tools for probing our Universe.

Imaging Software Shows Your Future Self

When people go to a hair stylist, they often browse magazines to find a photo of a style they want to try, but they won’t know if they really like it until they try it.
