It’s known that water ice exists below the lunar regolith (broken rock and dust), but scientists don’t yet understand whether surface ice frost covers the floors inside these cold craters. To find out, NASA is sending Lunar Flashlight, a small satellite (or SmallSat) no larger than a briefcase. Swooping low over the lunar South Pole, it will use lasers to shed light on these dark craters—much like a prospector looking for hidden treasure by shining a flashlight into a cave. The mission will launch aboard a SpaceX Falcon 9 rocket in mid-November.

“This launch will put the satellite on a trajectory that will take about three months to reach its science ,” said John Baker, the mission’s project manager at NASA’s Jet Propulsion Laboratory in Southern California. “Then Lunar Flashlight will try to find on the surface of the Moon in places that nobody else has been able to look.”

A ring-shaped waveguide with a particular pattern of notches can force a light wave to make two round trips before completing an integer number of wave cycles.

Light can travel along a closed path inside a ring of glass or similar material, reflecting repeatedly from the interior surface. Although such closed-loop waves generally have integer values of angular momentum, researchers using a small gear-shaped ring have now demonstrated an ability to generate similar waves with unusual fractional values of angular momentum [1]. As in a Möbius strip, the waves must make two round trips to return to their initial configuration. The ability to tune the angular momentum in this way could give researchers more precise control of light in advanced devices such as single-photon emitters.

Physicists refer to the closed-loop waves as whispering gallery modes, named after an acoustic effect in round rooms, where sounds reflect multiple times off the walls. Ordinarily, a wave of this kind moves around a single closed loop before retracing its earlier path. The phase of the electric field associated with the wave front must go through an integer number M of cycles in making one loop. Technically, this condition also implies that the photons associated with the wave will carry an integer number M units of angular momentum.

Five malicious dropper Android apps with over 130,000 cumulative installations have been discovered on the Google Play Store distributing banking trojans like SharkBot and Vultur, which are capable of stealing financial data and performing on-device fraud.

“These droppers continue the unstopping evolution of malicious apps sneaking to the official store,” Dutch mobile security firm ThreatFabric told The Hacker News in a statement.

“This evolution includes following newly introduced policies and masquerading as file managers and overcoming limitations by side-loading the malicious payload through the web browser.”

A recently discovered hacking group known for targeting employees dealing with corporate transactions has been linked to a new backdoor called Danfuan.

This hitherto undocumented malware is delivered via another dropper called Geppei, researchers from Symantec, by Broadcom Software, said in a report shared with The Hacker News.

The dropper “is being used to install a new backdoor and other tools using the novel technique of reading commands from seemingly innocuous Internet Information Services (IIS) logs,” the researchers said.

The mission team continues to complete testing of the spacecraft’s flight software in preparation for the 2023 launch date.

On Friday, October 29, NASA

Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is “To discover and expand knowledge for the benefit of humanity.” Its core values are “safety, integrity, teamwork, excellence, and inclusion.”

John J. Collins is Holmes Professor of Old Testament Criticism and Interpretation at Yale Divinity School and has served as president of both the Society of Biblical Literature and Catholic Biblical Association. His many other books include “Apocalypse, Prophecy, and Pseudepigraphy; Beyond the Qumran Community; and The Eerdmans Dictionary of Early Judaism.

Apocalyptic literature evokes an imaginative world that is set in deliberate counterpoint to the experiential world of the present. Apocalypticism thrives especially in times of crisis, and it functions by offering a resolution of the relevant crisis, not in practical terms but in terms of imagination and faith.

The Apocalyptic Imagination by John Collins is one of the most widely praised studies of Jewish apocalyptic literature ever written. And this second edition of Collins’s study represents a complete updating and rewriting of the original work. Especially noteworthy is the chapter on the Dead Sea Scrolls, which now takes into account all of the recently published texts. Other chapters discuss apocalypse as a literary genre, explore the phenomenon and function of apocalypticism in the ancient world, study a wide range of individual apocalyptic texts, and examine the apocalyptic character of early Christianity.

“We are very pleased that we can now start with the first activities to stimulate and consolidate cellular agriculture in the Netherlands,” said Ira van Eelen, CEO of KindEart. Tech and a board member of Cellular Agriculture Netherlands. “With this we can guarantee that the Netherlands remains the ideal place for cellular agriculture to thrive. We have a rich history in cellular agriculture and are a global leader in biotechnology, alternative proteins and food innovation. Supported by this visionary leadership that the Dutch government is showing again today, we will expand our team in the coming months and roll out the first activities around public research, scaling up, and education.”

Indeed, the Netherlands has been demonstrating considerable progress in developing cultured meat. In July, for example, Dutch company Meatable revealed its first lab-grown sausages, which are expected to go on sale to consumers by 2025. The addition of €60 million in government funding will make the Netherlands an even more attractive location for companies in the sector.

Currently a niche and miniscule part of the overall food market, cultured meat has potential to become another “exponential” technology – much like the semiconductor industry, solar energy, genome sequencing, and so on. The benefits in terms of animal welfare, climate change, food safety, antibiotic resistance, land and water usage could be substantial.

Picking your nose might seem harmless albeit gross, but new research is showing it may have some devastating consequences, according to a press release published by Griffith University Friday.

A direct path to the brain

The new research demonstrates that a bacteria can travel through the olfactory nerve in the nose and into the brain in mice, where it creates markers that are a tell-tale sign of Alzheimer’s disease.

Semiconductors are small, ubiquitous, and underappreciated. They are the brains of every modern device.

When Nancy Pelosi traveled to Taiwan in August, it made front-page news around the world and raised the specter of an all-out war between the U.S. and China.

Early in October, the Biden administration made a far more decisive move against China — but it barely made the news in Australia.

Biden decided to unequivocally sever China’s access to high-end computer chips (aka semiconductors).
