Scientists 'tune in' to proton spin precession

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a non-invasive way to measure the "spin tune" of polarized protons at the Relativistic Heavy Ion Collider (RHIC)—an important factor for maintaining these spinning particles' alignment.

Slippery when wet: How does lubrication work?

In a recent paper in Science Advances, researchers from the University of Amsterdam present new experimental insight into how lubrication works. They have developed a new method using fluorescent molecules to directly observe nanometric lubrication films with a sensitivity of a single molecular layer. Their quantitative description of the relation between topography, contact pressure and lubrication provides a deeper understanding of lubrication.

Colliding molecules and antiparticles

Antiparticles—subatomic particles that have exactly opposite properties to those that make up everyday matter—may seem like a concept out of science fiction, but they are real, and the study of matter-antimatter interactions has important medical and technological applications. Marcos Barp and Felipe Arretche from the Universidade Federal de Santa Catarina, Brazil have modelled the interaction between simple molecules and antiparticles known as positrons and found that this model agreed well with experimental observations. This study has been published in The European Physical Journal D.

Study leads to new approach to trapping light in photonic kagome crystals

A new approach to trapping light in artificial photonic materials by a City College of New York-led team could lead to a tremendous boost in the transfer speed of data online.

Astronomy & Space news

"Everything is determined by forces over which we have no control... Human beings, vegetables, or cosmic dust, we all dance to a mysterious tune, intoned in the distance by an invisible piper," Albert Einstein wrote.

Mars Express tracks the phases of Phobos

ESA's Mars Express has captured detailed views of the small, scarred and irregularly shaped moon Phobos from different angles during a unique flyby.

NASA's Juno navigators enable Jupiter cyclone discovery

Jupiter's south pole has a new cyclone. The discovery of the massive Jovian tempest occurred on Nov. 3, 2019, during the most recent data-gathering flyby of Jupiter by NASA's Juno spacecraft. It was the 22nd flyby during which the solar-powered spacecraft collected science data on the gas giant, soaring only 2,175 miles (3,500 kilometers) above its cloud tops. The flyby also marked a victory for the mission team, whose innovative measures kept the solar-powered spacecraft clear of what could have been a mission-ending eclipse.

Researchers participate in study that adds new detail to merger models

Scientists are getting better at modeling the complex tangle of physics properties at play in one of the most powerful events in the known universe: the merger of two neutron stars.

Researchers estimate the mass of the Milky Way to be 890 billion times that of our sun

Newfound Martian aurora actually the most common; sheds light on Mars' changing climate

A type of Martian aurora first identified by NASA's MAVEN spacecraft in 2016 is actually the most common form of aurora occurring on the Red Planet, according to new results from the mission. The aurora is known as a proton aurora and can help scientists track water loss from Mars' atmosphere.

Searching explanations for mysterious structures in protoplanetary disks

In the discs of dust and gasses around young stars, mysterious structures occur. Together with professor Ewine van Dishoeck, Ph.D. student Paolo Cazzoletti investigate how we can explain these forms, such as rings, spirals and holes. On 12 December, he will defend his thesis.

An upcoming ESA mission is going to remove one piece of space junk from orbit

While working at the NASA Johnson Space Center during the 1970s, astrophysicist Donald Kessler predicted that collisions of space debris would become increasingly common as the density of space debris increases in orbit around the Earth, creating a cascading effect. Since 2005, the amount of debris in orbit has followed an exponential growth curve, confirming Kessler's prediction.

X marks the spot: NASA selects site for asteroid sample collection

After a year scoping out asteroid Bennu's boulder-scattered surface, the team leading NASA's first asteroid sample return mission has officially selected a sample collection site.

Image: Hubble views galaxy's dazzling display

NGC 3175 is located around 50 million light-years away in the constellation of Antlia (the Air Pump). The galaxy can be seen slicing across the frame in this image from the NASA/ESA Hubble Space Telescope, with its mix of bright patches of glowing gas, dark lanes of dust, bright core, and whirling, pinwheeling arms coming together to paint a beautiful celestial scene.

Breathable atmospheres may be more common in the universe than we first thought

The existence of habitable alien worlds has been a mainstay of popular culture for more than a century. In the 19th century, astronomers believed that Martians might be using canal-based transport links to traverse the red planet. Now, despite living in an age when scientists can study planets light years from our own solar system, most new research continues to diminish the chances of finding other worlds on which humans could live. The biggest stumbling block may be oxygen—human settlers would need a high oxygen atmosphere in which to breathe.

RIT and IAR observe pulsars for the first time from South America

Rochester Institute of Technology and the Instituto Argentino de Radioastronomía (IAR) have collaborated to make the first pulsar observations from South America.

An IKEA furniture assembly environment to train robots on complex manipulation tasks

In order to complete complex everyday tasks such as using equipment, cooking or building furniture, robots should be able to plan their actions and manipulate objects in their surroundings. So far, however, teaching robots to complete complicated tasks, such as those that require planning over a considerable period of time, has proved to be rather challenging, also due to a lack of reliable simulated environments to test them in.

Research shows how Plundervolt could mess with Intel CPUs

Undervolting can bring trouble Intel would not care to endure at all. Fortunately, the latest research warning signals have won Intel's attention and they are addressing the situation.

Differences between deep neural networks and human perception

When your mother calls your name, you know it's her voice—no matter the volume, even over a poor cell phone connection. And when you see her face, you know it's hers—if she is far away, if the lighting is poor, or if you are on a bad FaceTime call. This robustness to variation is a hallmark of human perception. On the other hand, we are susceptible to illusions: We might fail to distinguish between sounds or images that are, in fact, different. Scientists have explained many of these illusions, but we lack a full understanding of the invariances in our auditory and visual systems.

Finding ground truth in social media

Is it possible to extract "journalistic" as opposed to "general" commentary from social media? Writing in the International Journal of Grid and Utility Computing, a team from Portugal describes an approach to human and automatic extraction of updates and reports one might describe as coming from citizen journalists. Their algorithm is trained on automatically annotated and human-annotated data sets and shows that the wholly automated approach homes in on "ground truth" data much more efficiently and effectively than when the data has had the human touch.
