The commonplace phenomenon of liquid drops falling from a surface is—perhaps surprisingly—not yet fully understood by scientists. Understanding the complex interactions between the forces involved here would be helpful in industry, where structured packings in cooling towers must be designed to encourage droplet formation in fluid flow but coatings mixed to maintain a pristine, smooth surface.

Furthermore, the design of meshes used to harvest clean water from fog or dew, where this is limited, relies on an understanding of how the water condenses on the fibers and drops into collection tanks.

Atefeh Pour Karimi, a Ph.D. student at the Institute of Heat and Mass Transfer, Aachen University, Germany, and her supervisors and collaborators have analyzed the dynamics of this type of flow in detail and published their findings in The European Physical Journal Special Topics.

A large-scale brute force password attack using almost 2.8 million IP addresses is underway, attempting to guess the credentials for a wide range of networking devices, including those from Palo Alto Networks, Ivanti, and SonicWall.

A brute force attack is when threat actors attempt to repeatedly log into an account or device using many usernames and passwords until the correct combination is found. Once they have access to the correct credentials, the threat actors can then use them to hijack a device or gain access to a network.

According to the threat monitoring platform The Shadowserver Foundation, a brute force attack has been ongoing since last month, employing almost 2.8 million source IP addresses daily to perform these attacks.

Brave Browser is getting a new feature called ‘custom scriptlets’ that lets advanced users inject their own JavaScript into websites, allowing deep customization and control over their browsing experience.

The new feature is coming in Brave Browser version 1.75 for the desktop and is very similar to the popular TamperMonkey and GreaseMonkey browser extensions, which allow users to create “user scripts” that modify the functionality of specific websites.

“Starting with desktop version 1.75, advanced Brave users will be able to write and inject their own scriptlets into a page, allowing for better control over their browsing experience,” explained Brave in the announcement.

The great solar storm of May 2024, which sparked beautiful auroral displays over much of the world, also created two new radiation belts that were observed with a satellite that came back from the dead.

“This is really stunning,” Xinlin Li, a professor at the Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder, said in a statement. “When we compared the data from before and after the storm, I said, ‘Wow, this is something really new’.”

The surface of Earth’s inner core may be shape-shifting, new research suggests.

The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the inner core, 3,200 miles (5,150 kilometers) deep. It revealed that, even when the core had rotated into a previously observed position, there were often subtle differences.

Sökandet efter intelligent utomjordiskt liv har börjat tas på större allvar inom akademin. Foliehatt-stämpeln är på väg att suddas bort, och till våren håller ett svenskt lärosäte för första gången en akademisk kurs om ufon.

A specialized version, Goku+, focuses on creating authentic-looking advertising clips featuring humans and products, which ByteDance says could reduce video ad production costs by 99 percent.

Nothing else in the animal kingdom packs a punch like the mantis shrimp. This tiny, colorful crustacean delivers a wallop at 23 meters per second – a king-hit delivering a jaw-dropping 1,500 newtons of force to crack open the shells of their prey.

These blows are so powerful that scientists have wondered how the crustacean itself remains intact against the recoil effects.

Now, they’ve uncovered one of its secrets. The dactyl clubs that rain down mantis shrimp pain have a fascinating structure that filters out shocks, protecting the animal behind them.

Formation of biomolecular condensates composed of proteins and RNA facilitates the regulation of gene expression by modulating translation or facilitating RNA processing. Now, synthetic ribonucleoprotein granules created with engineered intrinsically disordered proteins selectively sequester mRNA and enhance protein translation in cells. These highly liquid-like condensates exchange biomolecules across the cell and facilitate target mRNA and ribosome partitioning.
