Posted: 20 Jun 2018 02:09 PM PDT

A storm of tiny dust particles has engulfed much of Mars over the last two weeks and prompted NASA’s Opportunity rover to suspend science operations. But across the planet, NASA’s Curiosity rover, which has been studying Martian soil at Gale Crater, is expected to remain largely unaffected by the dust. The Martian dust storm has grown in size and is now officially a ‘planet-encircling’ (or ‘global’) dust event.


How physics explains the evolution of social organization

Learning about the Himalayas using Mars technology

Posted: 20 Jun 2018 02:09 PM PDT

he Himalayan Range includes some of the youngest and most spectacular mountains on Earth, but the rugged landscape that lends it the striking beauty for which it is known can also keep scientists from fully understanding how these mountains formed.

A team of scientists ran quantum simulations to develop a new model of the behavior of water at extremely high temperatures and pressures. The computational measurements should help scientists understand water’s role in the makeup of the mantle and potentially in other planets.


The seed that could bring clean water to millions

Posted: 20 Jun 2018 12:02 PM PDT

Scientist are refining a process that could soon help provide clean water to many in water-scarce regions. The process uses sand and plant materials readily available in many developing nations.


Scientists calculate impact of China’s ban on plastic waste imports

Posted: 20 Jun 2018 12:02 PM PDT

Scientists have calculated the potential global impact of China’s ban on plastic waste imports and how this policy might affect efforts to reduce the amount of plastic waste entering the world’s landfills and natural environment.


The sounds of climate change

Posted: 20 Jun 2018 12:02 PM PDT

Researchers describe a way to quickly sift through thousands of hours of field recordings to estimate when songbirds arrive at their Arctic breeding grounds. Their research could be applied to any dataset of animal vocalizations to understand how migratory animals are responding to climate change.


Gas flow through tiny atonically flat walls: Atomic-scale ping-pong

Posted: 20 Jun 2018 12:02 PM PDT

New experiments have shed more light on the gas flow through tiny, angstrom-sized channels with atomically flat walls.


Last of universe’s missing ordinary matter

Posted: 20 Jun 2018 12:00 PM PDT

Researchers have helped to find the last reservoir of ordinary matter hiding in the universe.


Chameleon-inspired nanolaser changes colors

Posted: 20 Jun 2018 12:00 PM PDT

Chameleons change color by controlling the spacing among nanocrystals on their skin. The nanolaser changes color similarly — by controlling the spacing among metal nanoparticles.


Mega-cruises are becoming copies of the great Las Vegas resorts

Posted: 20 Jun 2018 10:00 AM PDT

The productive improvements and innovations in the shipyards, which have made the mega ships possible, have made the cruise ship operators look for a leisure model that fills the abundant space that these new floating cities offer. In many of these ships, the classic model of luxury has been abandoned to copy, with great precision, the theme parks of the great casino resorts of Las Vegas.


Quantum step forward in protecting communications from hackers

Posted: 20 Jun 2018 09:59 AM PDT

Researchers have shown that a new quantum-based procedure for distributing secure information along communication lines could be successful in preventing serious security breaches.


Interaction of paired and lined-up electrons can be manipulated in semiconductors

Posted: 20 Jun 2018 09:59 AM PDT

The way that electrons paired as composite particles or arranged in lines interact with each other within a semiconductor provides new design opportunities for electronics, according to recent findings.


Crumple up this keyboard and stick it in your pocket

Posted: 20 Jun 2018 09:59 AM PDT

Bendable portable keyboards for use with computers and other electronic devices are already on the market, but they have limited flexibility, and they’re fairly sizable when rolled up for transport. Now researchers have crafted an inexpensive keyboard that is so tough, flexible and thin that it can be crumpled up and tucked in a pocket without damaging it.


Robot bloodhound tracks odors on the ground

Posted: 20 Jun 2018 09:59 AM PDT

Bloodhounds are famous for their ability to track scents over great distances. Now researchers have developed a modern-day bloodhound — a robot that can rapidly detect odors from sources on the ground, such as footprints. The robot could even read a message written on the ground using odors as a barcode.


Modern laser science brightened by 2,300-year-old technology

Posted: 20 Jun 2018 09:59 AM PDT

Scientists have harnessed a 2,300-year-old water displacement technology to develop a novel laser beam that traps and moves particles in specific directions. It is a significant contribution to the future of both basic and applied science.
