Best of both worlds: Asteroids and massive mergers

The University of Arizona's Steward Observatory has partnered with the Catalina Sky Survey, which searches for near-Earth asteroids from atop Mount Lemmon, in an effort dubbed Searches after Gravitational Waves Using ARizona Observatories, or SAGUARO, to find optical counterparts to massive mergers. "Catalina Sky Survey has all of this infrastructure

Are attitudes contagious? Nonverbal messages

A new Northwestern University study examined whether people can acquire attitudes toward other individuals from the nonverbal signals that are directed toward them.

How many Earth-like planets are around sun-like stars?

Thousands of planets have been discovered by NASA's Kepler space telescope.

Storms on Jupiter are disturbing the planet's colorful belts: Radio, IR and optical observations show evolution of plumes and their impact on belts and zones

Thanks to coordinated observations of the planet in January 2017 by six ground-based optical and radio telescopes and NASA's Hubble Space Telescope, a University of California, Berkeley, astronomer and her colleagues have been able to track the effects of these storms -- visible as bright plumes above the planet's ammonia

Materials that can revolutionize how light is harnessed for solar energy: Researchers develop new design rule for generating excitons will help advance next-generation devices

In a study published this month in Nature Chemistry, the team details the design of organic molecules that are capable of generating two excitons per photon of light, a process called singlet fission. The excitons are produced rapidly and can live for much longer than those generated from their inorganic

Roadmap for detecting changes in ocean due to climate change: Some impacts -- like sea temperature rise -- are already in progress; others expected to occur within next century

The study looked at physical and chemical changes to the ocean that are associated with rising atmospheric carbon dioxide due to human activities.

Mysterious release of radioactive material uncovered

Among the 70 experts from all over Europe who contributed data and expertise to the current study are Dieter Hainz and Dr.

Scurrying roaches help researchers steady staggering robots

Normally, tedious modeling of mechanics, electronics, and information science is required to understand how insects' or robots' moving parts coordinate smoothly to take them places.

Wearable sensors detect what's in your sweat: New easy-to-make sensors can provide real-time measurements of sweat rate and electrolytes and metabolites in perspiration

They hope that one day, monitoring perspiration could bypass the need for more invasive procedures like blood draws, and provide real-time updates on health problems such as dehydration or fatigue.

Type of brain cell involved in stuttering identified: Discovery could lead to targets for new therapies

The loss of astrocytes, a supporting cell in the brain, was most prominent in the corpus callosum, a part of the brain that bridges the two hemispheres.

Scratching the surface of how your brain senses an itch: Set of neurons in spinal cord help transmit a light-touch signal from skin to brain

Salk researchers have discovered how neurons in the spinal cord help transmit such itch signals to the brain.

Near-Earth asteroid 2006 QV89 not a threat for next century: Critical observation made on Maunakea during first night of return to operations

Observations of the near-Earth asteroid 2006 QV89 made on August 11 with the Canada-France-Hawaii Telescope (CFHT) have ruled out any potential future impact threat to Earth by this asteroid for the next century. 2006 QV89 was discovered on August 29, 2006, with a telescope in Arizona, and observations were only

Hurricanes drive the evolution of more aggressive spiders

Raging winds can demolish trees, defoliate entire canopies and scatter debris across forest floors, radically altering the habitats and reshaping the selective pressures on many organisms, suggests a new study published today in the journal Nature Ecology Evolution. "It is tremendously important to understand the environmental impacts of these 'black

July 2019 was hottest month on record for the planet: Polar sea ice melted to record lows

Here's a closer look into NOAA's latest monthly global climate report: Climate by the numbers: July 2019 The average global temperature in July was 1.71 degrees F above the 20th-century average of 60.4 degrees, making it the hottest July in the 140-year record, according to scientists at NOAA's

Moon glows brighter than sun in images from NASA's Fermi

Gamma-ray observations are not sensitive enough to clearly see the shape of the Moon's disk or any surface features.
