Gravitational lensing of the cosmic microwave background has been used to probe the distribution of dark matter around some of the earliest galaxies in the Universe.

Investigating the properties of galaxies is fundamental to uncovering the still-unknown nature of the dominant forms of mass and energy in the Universe: dark matter and dark energy. Dark matter resides in “halos” surrounding galaxies, and information on the evolution of this invisible substance can be obtained by examining galaxies over a wide range of cosmic time. But observing distant galaxies—those at high redshifts—poses a challenge for astronomers because these objects look very dim. Fortunately, there is another way to probe the dark matter around such galaxies: via the imprint it leaves on the pattern of cosmic microwave background (CMB) temperature fluctuations through gravitational lensing (Fig. 1).

Most measurements of Newton’s gravity constant use stationary masses, but a new experiment measures the constant with wiggling metal beams.

Researchers at the University of Massachusetts Amherst recently announced that they have figured out how to engineer a biofilm that harvests the energy in evaporation and converts it to electricity. This biofilm, which was announced in Nature Communications, has the potential to revolutionize the world of wearable electronics, powering everything from personal medical sensors to personal electronics.

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

“This is a very exciting technology,” says Xiaomeng Liu, graduate student in electrical and computer engineering in UMass Amherst’s College of Engineering and the paper’s lead author. “It is real green energy, and unlike other so-called ‘green-energy’ sources, its production is totally green.”

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.

A Sentinel One investigation revealed threat actors (TA) have been abusing the Windows Defender command line tool to decrypt and load Cobalt Strike payloads.

The cybersecurity experts detailed their findings in an advisory last week, in which they said the TA managed to carry out the attacks after obtaining initial access via the Log4Shell vulnerability against an unpatched VMware Horizon Server.

The attackers reportedly modified the Blast Secure Gateway component of the application by installing a web shell using PowerShell code.

The findings reportedly uncovered 475 web pages of elaborate ransomware products and services, alongside many high-profile groups aggressively marketing ransomware-as-a-service (RAAS).

Forensic Pathways also identified 30 different “brands” of ransomware, with some known names such as BlackCat, Egregor, Hidden Tear and WannaCry having been successfully used in high-profile attacks.

The research also suggested Ransomware strains used in high-profile attacks command a higher price for associated services.

And now, for old fashion Nuclear Doom.

UNITED NATIONS (AP) — The United Nations chief warned Monday that “humanity is just one misunderstanding, one miscalculation away from nuclear annihilation,” citing the war in Ukraine, nuclear threats in Asia and the Middle East and many other factors.
