Scientists produce 3D chemical maps of single bacteria

Posted by in category: biological

Scientists at the National Synchrotron Light Source II (NSLS-II)—a U.S. Department of Energy (DOE) Office of Science User Facility at DOE’s Brookhaven National Laboratory—have used ultrabright x-rays to image single bacteria with higher spatial resolution than ever before. Their work, published in Scientific Reports, demonstrates an X-ray imaging technique, called X-ray fluorescence microscopy (XRF), as an effective approach to produce 3D images of small biological samples.

Laser-activated nanotube skin shows where the strain is

Posted by in categories: nanotechnology, transportation

Whether they’re in airplane wings, bridges or other critical structures, cracks can cause catastrophic failure before they’re large enough to be noticed by the human eye. A strain-sensing “skin” applied to such objects could help, though, by lighting up when exposed to laser light.

An old-fashioned AI has won a Starcraft shootout

Posted by in categories: education, robotics/AI

En Taro AI


The latest results in a long-running contest of video-game-playing AIs reveal how hard it is for machines to master swarming insectoid Zergs or blitzing Protos. They also show that even old-school approaches can still sometimes win out.

The AIIDE Starcraft Contest has been running at Memorial University in Newfoundland, Canada, since 2010. Participating teams submit bots that play an original version of Starcraft, a sprawling sci-fi-themed game, in a series of one-on-one showdowns.

News: On the evening of Thursday, Nov. 15, NASA’s Kepler space telescope received its final set of commands to disconnect communications with Earth

Posted by in category: space travel

The “goodnight” commands finalize the spacecraft’s transition into retirement, which began on Oct. 30 with NASA’s announcement that Kepler had run out of fuel and could no longer conduct science.

Coincidentally, Kepler’s “goodnight” falls on the same date as the 388-year anniversary of the death of its namesake, German astronomer Johannes Kepler, who discovered the laws of planetary motion and passed away on Nov. 15, 1630.

Spacecraft Witness Explosion in Earth’s Magnetic Field

Posted by in categories: particle physics, satellites

Magnetic fields around the Earth release strong bursts of energy, accelerating particles and feeding the auroras that glow in the polar skies. On July 11, 2017, four NASA spacecrafts were there to watch one of these explosions happen.

The process that produces these bursts is called magnetic reconnection, in which different plasmas and their associated magnetic fields interact, releasing energy. The Magnetospehric Multiscale Mission (MMS) satellites launched in 2015 to study the places where this reconnection process occurs. This newly released research shows for the first time that the mission encountered one of these reconnection sites in the night side of the Earth’s magnetic field, which extends behind the planet as a long “magnetotail.”

New discovery shows glass made from exploding stars

Posted by in categories: cosmology, materials

The next time you’re gazing out of the window in search of inspiration, keep in mind the material you’re looking through was forged inside the heart of an exploding ancient star.

An international team of scientists said Friday they had detected —the main component of glass—in the remnants of two distant supernovae billions of from Earth.

Researchers used NASA’s Spitzer Space Telescope to analyse the light emitted by the collapsing mega-cluster and obtain silica’s “fingerprint” based on the specific wavelength of light the material is known to emit.

For eco-conscious city dwellers, urban agriculture is one road to real impact

Posted by in categories: climatology, habitats, sustainability

Eco-consciousness is a hot trend. It’s become common occurrence to see shoppers with reusable grocery totes at the supermarket. Bamboo straws are flying off shelves as people opt for eco-friendly products. Urban gardening and composting, too, has taken root as consumers try to minimize their carbon footprints.

These small actions are encouraging first steps, but they’re not enough when it comes to tackling agricultural contributions to climate change. Strong-worded warnings from the UN’s Intergovernmental Panel on Climate Change (IPCC) detail the potential for climate disasters to worsen if modern consumption patterns don’t change — and soon.

There’s evidence that reimagining urban environments’ food systems might help reduce carbon emissions. With more than 60% of the global population expected to live in cities by 2030, urban agriculture might be one piece of the puzzle for reducing strain on city resources. The practice typically involves growing food in smaller, city environments such as on rooftops, apartment balconies, or even walls.
