Shaky cameras can make for sharper shots, new research shows

It doesn’t take an expert photographer to know that the steadier the camera, the sharper the shot. But that conventional wisdom isn’t always true, according to new research led by Brown University engineers.

The researchers showed that with the help of a clever algorithm, a camera in motion can produce higher-resolution images than a camera held completely still. The new image processing technique could enable gigapixel-quality images from run-of-the-mill camera hardware, as well as sharper imaging for scientific or archival photography.

“We all know that when you shake a camera, you get a blurry picture,” said Pedro Felzenszwalb, a professor of engineering and computer science at Brown. “But what we show is that an image captured by a moving camera actually contains additional information that we can use to increase .”

A twist in spintronics: Chiral magnetic nanohelices control spins at room temperature

Spintronics, or spin-electronics, is a revolutionary approach to information processing that utilizes the intrinsic angular momentum (spin) of electrons, rather than solely relying on electric charge flow. This technology promises faster, more energy-efficient data storage and logic devices. A central challenge in fully realizing spintronics has been the development of materials that can precisely control electron spin direction.

In a new development for spin-nanotechnology, researchers led by Professor Young Keun Kim of Korea University and Professor Ki Tae Nam of Seoul National University have successfully created magnetic nanohelices that can control electron spin.

This technology, which utilizes chiral magnetic materials to regulate electron spin at room temperature, has been published in Science.

GhostRedirector Hacks 65 Windows Servers Using Rungan Backdoor and Gamshen IIS Module

Cybersecurity researchers have lifted the lid on a previously undocumented threat cluster dubbed GhostRedirector that has managed to compromise at least 65 Windows servers primarily located in Brazil, Thailand, and Vietnam.

The attacks, per Slovak cybersecurity company ESET, led to the deployment of a passive C++ backdoor called Rungan and a native Internet Information Services (IIS) module codenamed Gamshen. The threat actor is believed to be active since at least August 2024.

“While Rungan has the capability of executing commands on a compromised server, the purpose of Gamshen is to provide SEO fraud as-a-service, i.e., to manipulate search engine results, boosting the page ranking of a configured target website,” ESET researcher Fernando Tavella said in a report shared with The Hacker News.
