A special bonding state between atoms has been created in the laboratory for the first time: With a laser beam, atoms can be polarized so that they are positively charged on one side and negatively charged on the other. This makes them attract each other creating a very special bonding state—much weaker than the bond between two atoms in an ordinary molecule, but still measurable. The attraction comes from the polarized atoms themselves, but it is the laser beam that gives them the ability to do so—in a sense, it is a “molecule” of light and matter.

Theoretically, this effect has been predicted for a long time, but now scientists at the Vienna Center for Quantum Science and Technology (VCQ) at TU Wien, in cooperation with the University of Innsbruck, have succeeded in measuring this exotic atomic bond for the first time. This interaction is useful for manipulating extremely cold atoms, and the effect could also play a role in the formation of molecules in space. The results have now been published in the scientific journal Physical Review X.

Researchers have reported the discovery of an exoplanet orbiting Ross 508 near the inner edge of its habitable zone.

Researchers have uncovered a list of 3,207 mobile apps that are exposing Twitter API keys in the clear, some of which can be utilized to gain unauthorized access to Twitter accounts associated with them.

The takeover is made possible, thanks to a leak of legitimate Consumer Key and Consumer Secret information, respectively, Singapore-based cybersecurity firm CloudSEK said in a report exclusively shared with The Hacker News.

“Out of 3,207,230 apps are leaking all four authentication credentials and can be used to fully take over their Twitter Accounts and can perform any critical/sensitive actions,” the researchers said.

Hubble has taken somewhat of a backseat since the James Webb Space Telescope (JWST) began taking its first high resolution images of deep space last month. The first images shared by NASA from the newest space telescope were truly awe inspiring. But the space agency does not want you to forget one of its predecessors, the Hubble telescope, which has been inducing oohs and ahhs with its photos of space since its launch and deployment by the space shuttle Discovery in 1990.

One of the images that enamored viewers seven years ago, was recently shared by NASA on its Instagram feed once again. The image captured a sweeping bird’s-eye view of the Andromeda galaxy (M31), and is the sharpest large composite ever taken of the Milky Way’s neighbor. Even though Andromeda resides over 2 million light-years away, Hubble showed its photographic prowess to resolve individual stars in a 61,000 light-year-long stretch of the galaxy’s pancake-shaped disk.

A new method of radiation-resistant computer data storage called watermark storage that’s been developed by a University of Alabama in Huntsville (UAH) professor leading a student team has direct applications in the nuclear power and space industries.

“Data-driven analytics are growing exponentially for space and nuclear environments,” says Dr. Biswajit Ray, an assistant professor of electrical and at UAH, a part of the University of Alabama System.

He says the new storage system doesn’t rely on an electronic charge for NAND flash storage, as traditional data drives do. NAND stands for the “not and” type of flash memory, which is in common use. Interestingly, the watermark storage method requires no new components.

August is ‘looking pretty good’ for the historic Artemis I mission, says Draper’s Pete Paceley.

An immense amount of work goes into programming the manual astronaut override for NASA’s upcoming crewed Artemis missions. As Pete Paceley, principal director of Civil and Commercial Space Systems at Draper, points out on a call with IE, “we don’t want them to ever have to use manual control — but it’s necessary from a safety standpoint.”

Full Story:

Principal director of Civil and Commercial Space Systems at Draper Pete Paceley told us that August is ‘looking pretty good’ for Artemis I mission.

An international team of researchers has observed part of the formation of a dwarf galaxy, helping to explain how they evolve from a dwarf state to maturity. In their paper published in the journal Nature, the group describes finding evidence of maturation in such galaxies.

Prior research has shown that there are dwarf galaxies in the universe. Such galaxies are typically made up of just a few billion stars, as compared to mature galaxies such as the Milky Way, which have 200 to 400 billion stars. Prior research has also suggested that some dwarf galaxies might evolve to become more mature galaxies, but how that might happen has not been clear. In this new effort, the researchers focused the AstroSat space-based telescope on several blue compact dwarf galaxies, which are calculated to be approximately 1.5 to 3.9 billion light-years from Earth. The team then used the ultraviolet imaging telescope aboard AstroSat, which is India’s first multi-wavelength space telescope, to look for evidence of star formation activity.

Prior efforts to observe in dwarf galaxies have been hindered by their low luminosities, and the low mass of the objects they contain. These problems have been overcome with AstroSat due to the high resolving power of its and because of its ability to capture multiple wavelengths of light at the same time, and also because it was fitted with UV deep field imaging technology.

Possibilities Are Endless — iHLS.

This post is also available in: he עברית (Hebrew)

A new type of technology has recently been developed. AI technology that mimics the human eye. Researchers at the University of Central Florida have created a device for AI that replicates the retina of the eye. This new discovery can lead to AI that can immediately identify objects, such as automated descriptions of photos captured with a camera or a phone. This technology can potentially be used in autonomous robots and self-driving cars as well.

Scidaily.com reports that this technology performs better than the eye in terms of the range of wavelengths it can perceive, from ultraviolet to visible light and on to the infrared spectrum. The technology expands upon previous work by the research team that created brain-like devices that can enable AI to work in remote regions and space.
