Researchers discover world's most extreme hearing animal

Tweet

Researchers at the University of Strathclyde have discovered that the greater wax moth is capable of sensing sound frequencies of up to 300kHz – the highest recorded frequency sensitivity of any animal in the natural world.

Humans are only capable of hearing sounds of 20kHz maximum, dropping to around 12-15kHz as we age, and even dolphins, known exponents of ultrasound, can't compete as their limitations are around 160kHz.

Satellite captures night-time image of California's Springs fire

Tweet

From its orbit around the Earth, the NASA-NOAA Suomi National Polar-orbiting Partnership satellite or Suomi NPP satellite, captured a night-time image of California's Springs Fire.

The Suomi NPP satellite carries an instrument so sensitive to low light levels that it can detect wildfires in the middle of the night. The Day/Night band on Suomi/NPP produces Night-Time visible imagery using illumination from natural (the moon, forest fires) and man-made sources (city lights, gas flares).

New analysis suggests wind, not water, formed mound on Mars

Tweet

A roughly 3.5-mile high Martian mound that scientists suspect preserves evidence of a massive lake might actually have formed as a result of the Red Planet's famously dusty atmosphere, an analysis of the mound's features suggests. If correct, the research could dilute expectations that the mound holds evidence of a large body of water, which would have important implications for understanding Mars' past habitability.

5,000 steps a day to avoid paying higher health insurance costs? When money talks, people walk

Tweet

ANN ARBOR, Mich. — It was a controversial move when a health insurer began requiring people who were obese to literally pay the price of not doing anything about their weight – but it worked, a new study finds.

When people had to choose between paying up to 20 percent more for health insurance or exercising more, the majority of enrollees met fitness goals one step at a time via an Internet-tracked walking program, according to a joint study by the University of Michigan Health System and Stanford University.

AFOSR-funded research key to revolutionary 'green' spacecraft propellant

Tweet

In 2015, NASA, for the first time, will fly a space mission utilizing a radically different propellant—one which has reduced toxicity and is environmentally benign. This energetic ionic liquid, or EIL, is quite different from the historically employed hydrazine-based propellant, which was first used as a rocket fuel during World War II for the Messerschmitt Me 163B (the first rocket-powered fighter plane).

Satellite animation shows smoke from California's Springs fire

Tweet

On May 3, 2013, the NOAA GOES infrared and visible imagery were combined to create an animation that showed the plume of smoke from the fire. The smoke plume is seen blowing west and out over the eastern Pacific Ocean. The animation runs 17 seconds and shows the smoke plume from May 3 at 1415 to 2000 UTC (10:15 a.m. to 4 p.m. EDT) was created by the NASA GOES Project, located at NASA's Goddard Space Flight Center, Greenbelt, Md.

Zeal to ensure clean leafy greens takes bite out of riverside habitat in California

Meticulous attention to food safety is a good thing. As consumers, we like to hear that produce growers and distributers go above and beyond food safety mandates to ensure that healthy fresh fruits and vegetables do not carry bacteria or viruses that can make us sick.
