Detecting Methane from Miles Away

Posted by in category: electronics

A new laser-based field instrument developed by a collaborative team of researchers can quantify methane leaks as tiny as 1/4 of a human exhalation from nearly…a mile away. The system, constructed around a dual-frequency comb spectrometer, provides efficient, accurate data collection at a fraction of the cost of previous technologies. The research was partially funded by DARPA’s Spectral Combs from UV to THz (SCOUT) program.

The travelling speed camera

Posted by in categories: cosmology, electronics

The ULTRACAM has been a staple in ESO for almost 16 years. This high-speed camera is able to do 500 photographs per second in three different wavelengths and, since 2002 has been operating at the William Herschel Telescope at La Palma (Canary Islands, Spain), the New Technology Telescope at La Silla (Chile) (where this picture was taken) and, most recently, at the Very Large Telescope at Paranal (Chile) and the Thai National Telescope at Chiang Mai (Thailand).

Some of its past targets have included: the study of black holes, “hot-Jupiters” or variable stars.

World’s tallest active geyser may be erupting deep in Yellowstone National Park

Posted by in category: electronics

The tallest active geyser in the world may be erupting for the first time since 2014, according to the National Park Service.

Yellowstone National Park employees reported seeing the Steamboat Geyser erupt on Thursday evening, the park service announced Friday. Park geologists then compared the accounts to thermal sensors in the area and determined it “could be a series of minor eruptions.”

MIT Engineers Have Built a Device That Pulls Electricity Out of Thin Air

Posted by in category: electronics

Temperature changes large and small are happening around us all the time, and scientists have come up with a machine that can convert those fluctuations into electricity, potentially powering sensors and communication devices almost out of thin air.

The energy harvesting is done through what’s called a thermal resonator: a device that captures heat on one side and radiates it over to the other. As both sides try and reach equilibrium, the energy can be caught using the process of thermoelectrics.

According to the team from the Massachusetts Institute of Technology, the new thermal resonator could keep remote sensors or any off-grid devices powered up for years, just by using temperature swings – like the natural ones between night and day, for instance.

Researchers Have Created a New Camera Capable of Seeing Through the Human Body

Posted by in categories: biotech/medical, electronics

For many years doctors have been able to get a look inside a person’s body using X-ray scans, or placing a tiny camera inside the body. But those tools provide a limited view and can only reveal so much. A recently developed camera, however, may give doctors the ability to see everything happening in the human body, no matter where it is.

The camera was developed by researchers from the University of Edinburgh, and it’s meant to work while paired with an endoscope — a long, slender piece of equipment that usually has a camera, sensors, and lights at its tip.

Light emitted by the endoscope typically scatters when it comes into contact with structures within the body, such as body tissue, but the new camera is able to pick up on it thanks to the photon detectors inside of it. The camera is able to detect light sources behind as much as 20 centimeters (7.9 inches) of bodily tissue.
