Physics news

Surprising communication between atoms could improve quantum computing

A group of University of Wisconsin–Madison physicists has identified conditions under which relatively distant atoms communicate with each other in ways that had previously only been seen in atoms closer together—a development that could have applications to quantum computing.

Estimating risk of airborne COVID-19 with mask usage, social distancing

The continued increase in COVID-19 infection around the world has led scientists from many different fields, including biomedicine, epidemiology, virology, fluid dynamics, aerosol physics, and public policy, to study the dynamics of airborne transmission.

Astronomy and Space news

Data reveals evidence of molecular absorption in the atmosphere of a hot Neptune

An international team of scientists recently measured the spectrum of the atmosphere of a rare hot Neptune exoplanet, whose discovery by NASA's Transiting Exoplanet Survey Satellite (TESS) was announced just last month.

Tiny moon shadows may harbor hidden stores of ice

Hidden pockets of water could be much more common on the surface of the moon than scientists once suspected, according to new research led by the University of Colorado Boulder. In some cases, these tiny patches of ice might exist in permanent shadows no bigger than a penny.

New sub-Saturn-mass exoplanet discovered

Using the microlensing technique, an international team of astronomers has detected a new distant alien world. The newly found exoplanet, designated OGLE-2018-BLG-0799Lb, is about five times less massive than Jupiter and orbits a very low-mass dwarf. The finding is reported in a paper published October 17 on the arXiv pre-print server.

SOFIA discovers water on sunlit surface of moon

NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, water on the sunlit surface of the Moon. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places.

Asteroid samples escaping from jammed NASA spacecraft

A NASA spacecraft is stuffed with so much asteroid rubble from this week's grab that it's jammed open and precious particles are drifting away in space, scientists said Friday.

OSIRIS-REx spacecraft collects large sample of asteroid surface material, NASA confirms

Two days after touching down on asteroid Bennu, NASA's University of Arizona-led OSIRIS-REx mission team received images confirming that the spacecraft has collected more than enough material to meet one of its main mission requirements—acquiring at least 2 ounces, or 60 grams, of the asteroid's surface material.

The first habitable-zone, Earth-sized planet discovered with exoplanet survey spacecraft

TESS, the Transiting Exoplanet Survey Satellite, was launched in 2018 with the goal of discovering small planets around the Sun's nearest neighbors, stars bright enough to allow for follow-up characterizations of their planets' masses and atmospheres. TESS has so far discovered seventeen small planets around eleven nearby stars that are M dwarfs—stars that are smaller than the Sun (less than about 60% of the Sun's mass) and cooler (surface temperatures less than about 3900 kelvin). In a series of three papers that appeared together this month, astronomers report that one of these planets, TOI-700d, is Earth-sized and also located in its star's habitable zone; they also discuss its possible climate.

Astronomers enlist AI in the search for 'lethal' baby star eruptions

Young stars—just like young humans—are prone to temper flares. But star flares can incinerate everything around them, including the atmospheres of nearby planets starting to form.

Study offers more complete view of massive asteroid Psyche

A new study authored by Southwest Research Institute planetary scientist Dr. Tracy Becker discusses several new views of the asteroid 16 Psyche, including the first ultraviolet observations. The study, which was published today in The Planetary Science Journal and presented at the virtual meeting of the American Astronomical Society's Division for Planetary Sciences, paints a clearer view of the asteroid than was previously available.

The magnetic fields of the jellyfish galaxy JO206

An international team of astronomers has gained new insights into the physical conditions prevailing in the gas tail of so-called jellyfish galaxies. They are particularly interested in the parameters that lead to the formation of new stars in the tail outside the galaxy disk. They analyzed, for example, the strength and orientation of the magnetic fields in the galaxy JO206.

OSIRIS-REx spacecraft goes for early stow of asteroid sample

NASA's OSIRIS-REx mission is ready to perform an early stow on Tuesday, Oct. 27, of the large sample it collected last week from the surface of the asteroid Bennu to protect and return as much of the sample as possible.

About 3% of Starlink satellites have failed so far

SpaceX has drawn plenty of praise and criticism with the creation of Starlink, a constellation that will one day provide broadband internet access to the entire world. To date, the company has launched over 800 satellites and (as of this summer) is producing them at a rate of about 120 a month. There are even plans to have a constellation of 42,000 satellites in orbit before the decade is out.

SpaceX starship passes static fire test with three raptor engines, finally gets nose cone

It's beginning to look like SpaceX will attempt to make the 15-kilometer (9.3-mile) hop test before Christmas. After two successful 150-meter (~500 foot) hops with the SN5 and SN6 prototypes, engineers at SpaceX's Boca Chica launch facility in South Texas rolled out the SN8—the first Starship prototype to have three Raptor engines. But before the SN8 can conduct a high-altitude test flight, the engineers needed to run a static fire test.

Capacitivo: A contact-sensitive technique that can be used to make smart tablecloths

A team of researchers at Dartmouth College, working with Microsoft Corp., has developed a contact-sensitive object-recognition technique called Capacitivo for creating interactive fabrics. In their paper published on the ACM digital library site for the upcoming User Interface Software and Technology Conference, the group describes their technique and how well the prototype they built worked when tested.

Facebook demands academics disable ad-targeting data tool

Academics, journalists and First Amendment lawyers are rallying behind New York University researchers in a showdown with Facebook over its demand that they halt the collection of data showing who is being micro-targeted by political ads on the world's dominant social media platform.

Team examines operating limits in solid-state batteries to improve driving range of electric vehicles

There is huge momentum toward adoption of battery electric vehicles primarily because performances are meeting or exceeding the properties of traditional automobiles. Consumers want electric vehicles that have similar driving range (energy density) and charging styles and times (power density) to gasoline powered vehicles.

AI improves control of robot arms

More than one million American adults use wheelchairs fitted with robot arms to help them perform everyday tasks such as dressing, brushing their teeth, and eating. But the robotic devices now on the market can be hard to control. Removing a food container from a refrigerator or opening a cabinet door can take a long time. And using a robot to feed yourself is even harder because the task requires fine manipulation.

Powering the future: new insights into how alkali-metal doped flexible solar cells work

"When eco-friendly, inexpensive, versatile, and efficient solar cells are developed, all thermal and nuclear power plants will disappear, and solar cells installed over the ocean or in outer space will power our world," says Professor Dong-Seon Lee of the Gwangju Institute of Science and Technology in Korea. His highly optimistic view of the future mirrors the visions of many researchers involved in the effort to improve solar cells.

Bridges with limb-inspired architecture can withstand earthquakes, cut repair costs

Structural damage to any of the nation's ailing bridges can come with a hefty price of billions of dollars in repairs. New bridge designs promise more damage-resistant structures and, consequently, lower restoration costs. But if these designs haven't been implemented in the real world, predicting how they can be damaged and what repair strategies should be implemented remain unresolved.
