Study unveils new nonlinear dynamics of spinning bosonic stars

Although researchers have been studying dark matter and trying to observe it, its nature is a longstanding scientific mystery. The standard cosmological model suggests that approximately one-quarter of cosmological energy and matter is almost immune to electromagnetic interactions, thus the only way to observe it is to study its gravitational effects. However, the type of particles that make up dark matter is still a subject of debate.

Is there dark matter at the center of the Milky Way?

MIT physicists are reigniting the possibility, which they previously had snuffed out, that a bright burst of gamma rays at the center of our galaxy may be the result of dark matter after all.

Tiny quantum sensors watch materials transform under pressure

Since their invention more than 60 years ago, diamond anvil cells have made it possible for scientists to recreate extreme phenomena—such as the crushing pressures deep inside the Earth's mantle—or to enable chemical reactions that can only be triggered by intense pressure, all within the confines of a laboratory apparatus that you can safely hold in the palm of your hand.

Ghost imaging speeds up super-resolution microscopy

Researchers have used advanced imaging approaches to achieve super-resolution microscopy at unprecedented speeds. The new method should make it possible to capture the details of processes occurring in living cells at speeds not previously possible.

Does tapping your can of beer really keep it from fizzing all over you?

A team of researchers at the University of Denmark has tested the popular notion that tapping a can of beer after it has been shaken will prevent it from spraying when it is opened. Their paper describes a trial they carried out along with their conclusions, and is available on the arXiv preprint server.

New technology improves gravitational wave detectors by cutting quantum noise

Physicists have successfully developed a new instrument that significantly reduces quantum-level noise that has thus far limited experiments' ability to spot gravitational waves. Collisions between massive black holes and stars are thought to generate these ripples in space-time that were first detected in 2015. In all, about 11 detections have been fully confirmed so far.

(Noise)less is more

A group of researchers from Osaka University led by Prof. Masayuki Abe and Prof. Hiroshi Toki of the Graduate School of Engineering Science developed a high precision 3-D circuit simulator in the time-domain for quantifying electromagnetic (EM) noise and elucidated its origin, allowing for electronic and electrical circuit layout to reduce EM noise.

Scientists map Mars' global wind patterns for the first time

Today, a paper published in Science documents for the first time the global wind circulation patterns in the upper atmosphere of a planet, 120 to 300 kilometers above the surface. The findings are based on local observations, rather than indirect measurements, unlike many prior measurements taken on Earth's upper atmosphere. But it didn't happen on Earth: it happened on Mars. On top of that, all the data came from an instrument and a spacecraft that weren't originally designed to collect wind measurements.

The return to Venus and what it means for Earth

Sue Smrekar really wants to go back to Venus. In her office at NASA's Jet Propulsion Laboratory in Pasadena, California, the planetary scientist displays a 30-year-old image of Venus' surface taken by the Magellan spacecraft, a reminder of how much time has passed since an American mission orbited the planet. The image reveals a hellish landscape: a young surface with more volcanoes than any other body in the solar system, gigantic rifts, towering mountain belts and temperatures hot enough to melt lead.

Research group confirm planet-mass objects in extragalactic systems

A University of Oklahoma research group is reporting the detection of extragalactic planet-mass objects in a second and third galaxy beyond the Milky Way after the first detection in 2018. With the existing observational resources, it is impossible to directly detect planet-mass objects beyond the Milky Way and to measure its rogue planetary population.

Martian aurora offers climate change clues, research reports

A newly published study, presented on Dec. 12 at the American Geophysical Union (AGU) meeting, reveals that a type of Martian aurora originally detected by NASA's MAVEN spacecraft is in fact the most common aurora on the Red Planet, Embry-Riddle Aeronautical University researchers said.

NASA's NICER delivers best-ever pulsar measurements, first surface map

Astrophysicists are redrawing the textbook image of pulsars, the dense, whirling remains of exploded stars, thanks to NASA's Neutron star Interior Composition Explorer (NICER), an X-ray telescope aboard the International Space Station. Using NICER data, scientists have obtained the first precise and dependable measurements of both a pulsar's size and its mass, as well as the first-ever map of hot spots on its surface.

Interstellar comet 2I/Borisov swings past sun

When astronomers see something in the universe that at first glance seems like one-of-a-kind, it's bound to stir up a lot of excitement and attention. Enter comet 2I/Borisov. This mysterious visitor from the depths of space is the first identified comet to arrive here from another star. We don't know from where or when the comet started heading toward our Sun, but it won't hang around for long. The Sun's gravity is slightly deflecting its trajectory, but can't capture it because of the shape of its orbit and high velocity of about 100,000 miles per hour.

NRL-camera aboard NASA spacecraft confirms asteroid phenomenon

A U.S. Naval Research Laboratory-built camera mounted on the NASA Parker Solar Probe revealed an asteroid dust trail that has eluded astronomers for decades.

Short-lived light sources discovered in the sky

A project lead by an international team of researchers use publicly available data with images of the sky dating as far back as the 1950s to try to detect and analyse objects that have disappeared over time. In the project "Vanishing & Appearing Sources during a Century of Observations" (VASCO), they have particularly looked for objects that may have existed in old military sky catalogues from the 1950s, not to be found again in modern sky surveys. Among the physical indicators that they are looking for are stars that have vanished in the Milky Way.

Surface organometallic chemistry could open new paths for synthetic fuels and energy carriers

To convert hydrocarbons into fuel, the petrochemical industry currently relies primarily on heterogeneous catalysts, which in most cases contain active metal sites with poorly defined structures. In recent years, however, an area of study known as surface organometallic chemistry (SOMC) has enabled the design and development of far more defined, so-called single-site catalysts, in which metal sites can be tailored to meet specific requirements.

Google engineers raise the flag on AR depth, seek builders

So, a smartphone camera is just good for taking snapshots? Don't bring such talk to Google's augmented reality engineers. Blending the real and the virtual—-and winning special props for blending the real with the virtual—is what Google has in mind as a motivator for developers wanting to go deep into AR.

Taking the carbon out of construction with engineered wood

To meet the long-term goals of the Paris Agreement on climate change—keeping global warming well below 2 degrees Celsius and ideally capping it at 1.5 C—humanity will ultimately need to achieve net-zero emissions of greenhouse gases (GHGs) into the atmosphere. To date, emissions reduction efforts have largely focused on decarbonizing the two economic sectors responsible for the most emissions, electric power and transportation. Other approaches aim to remove carbon from the atmosphere and store it through carbon capture technology, biofuel cultivation, and massive tree planting.

Locking down your smart home with blockchain

The concept of the smart home has been around for many decades, but it is only in recent years with the advent of the so-called "internet of things," IoT, that meters and monitoring, cameras, locking systems, heating systems, and entertainment and information devices, have led to many homes having some degree of genuine smartness. Of course, with connectivity and utility come security problems. For instance, a malicious third party might find access to the home's wireless network, reprogram the smart TV, turn up the heating, disable the air conditioning, or even open the front door and allow them to remove all your smart devices and redeploy them elsewhere.

Diversify power sources to avoid a repeat of blackouts, study suggests
