Previously unknown RNA chaperone guides assembly of key poxvirus protein complex

A study from Würzburg reveals that pox viruses have developed a unique strategy to rapidly multiply after infecting a host cell. The findings uncover a previously unknown role for a well-known molecule and may serve as a starting point for the development of new antiviral agents.

In the English society of former times, a chaperone, traditionally an older woman, was assigned to accompany a young unmarried woman to ensure her proper behavior, especially during interactions with men, in line with the social norms of the time.

In biochemistry, chaperones also play a protective role. One of their main functions is to assist newly synthesized proteins in folding correctly and to prevent misfolded protein chains from clumping.

Similarities between human and AI learning offer intuitive design insights

New research has found similarities in how humans and artificial intelligence integrate two types of learning, offering new insights about how people learn as well as how to develop more intuitive AI tools.

The study is published in the Proceedings of the National Academy of Sciences.

Led by Jake Russin, a postdoctoral research associate in at Brown University, the study found by training an AI system that flexible and incremental learning modes interact similarly to working memory and long-term memory in humans.

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.

UCLA Engineers Build Room-Temperature Quantum-Inspired Computer

Experimental device harnesses quantum properties for efficient processing at room temperature. Engineers are working to design computers capable of handling a difficult class of tasks known as combinatorial optimization problems. These challenges are central to many everyday applications, includi

Caltech Physicists Discover “Double Helix,” a New Equilibrium State of Cosmic Plasma

Caltech experiments uncovered a stable double helix state in plasma flux ropes. The same principles explain cosmic structures such as the Double Helix Nebula. Research into the Sun’s outer atmosphere has led Caltech applied physics professor Paul Bellan and his former graduate student Yang Zhang

If Aliens Are Looking for Us, This Is How They’d Find Us

A new study of human deep space communications identifies the regions of space where signals from extraterrestrial intelligence are most likely to be detected. If an extraterrestrial civilization were trying to detect human signals, where and when would they be most likely to find them? A recent

“Alien Aurora” — Scientists Spot Never-Before-Seen Plasma Waves in Jupiter’s Polar Lights

Research offers new insights into protecting Earth from harmful solar radiation. A team at the University of Minnesota Twin Cities has identified and studied a previously unknown type of plasma wave within Jupiter’s aurora. The discovery provides new insight into auroral activity on other planets

41,000 Years Ago, Something Weird in Space Changed How Humans Lived on Earth

Weak magnetic fields once exposed humans to radiation. People adapted with shelter, clothing, and mineral protection. Our first meeting was a bit awkward. One of us is an archaeologist who studies how past peoples interacted with their environments. Two of us are geophysicists who investigate int
