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 .”

Quantum entanglement lasts 600 times longer in elusive dark states, study finds

A research team affiliated with UNIST has successfully demonstrated the experimental creation of collective quantum entanglement rooted in dark states—previously confined to theoretical models. The findings are published online in Nature Communications.

Unlike bright states, dark states are highly resistant to external disturbances and exhibit remarkably extended lifetimes, making them promising candidates for next-generation quantum technologies such as and ultra-sensitive sensors.

Led by Professor Je-Hyung Kim in the Department of Physics at UNIST, in collaboration with Dr. Changhyoup Lee from the Korea Research Institute of Standards and Science (KRISS) and Dr. Jin Dong Song from the Korea Institute of Science and Technology (KIST), the team has achieved the controlled induction of dark state-based collective entanglement. Remarkably, this entanglement exhibits a lifetime approximately 600 times longer than that of conventional bright states.

Shaping future electronics with light: Experiment demonstrates ultrafast light control of ferroelectric properties

Ferroelectrics are seen as promising candidates for the electronics of tomorrow. An experiment at the world’s largest X-ray laser—the European XFEL in Schenefeld near Hamburg—now shows that their properties can be controlled with high precision at ultrafast time scales—using light.

Scientists Discover a New Crystal That Breathes Oxygen

A potential game-changer for fuel cells, smart windows, and next-generation electronics

A team of scientists from Korea and Japan has discovered a new type of crystal that can “breathe”—releasing and absorbing oxygen repeatedly at relatively low temperatures. This unique ability could transform the way we develop clean energy technologies, including fuel cells, energy-saving windows, and smart thermal devices.

Researchers decode tertiary structure of DNA aptamer–ATP complex and improve binding affinity

DNA aptamers are powerful molecular tools in biosensing, bioimaging and therapeutics. However, a limited understanding of their tertiary structures and binding mechanisms hinders their further optimizations and applications.

Adenosine triphosphate (ATP), a central metabolite in cellular energy metabolism, is a key target for development. A DNA aptamer 1301b has recently been reported to bind to one molecule of ATP with a dissociation constant (KD) of ~2.5 µM. However, the structural basis for ATP recognition by 1301b remains unclear, lacking guiding principles for rational optimization.

In a study published in PNAS, a team led by Prof. Tan Weihong, Prof. Han Da, and Prof. Guo Pei from the Hangzhou Institute of Medicine (HIM) of the Chinese Academy of Sciences determined the tertiary structure of a DNA aptamer-ATP 1:1 binding complex, revealed the recognition mechanism, and engineered an optimized DNA aptamer with a submicromolar KD for ATP binding, which exhibited the highest affinity reported for ATP-binding DNA aptamers to date.

Groundbreaking new cancer detection replaces toxic compounds with diamonds

Scientists have developed a diamond-based sensor that could make it easier for doctors to detect the spread of cancer.

Researchers at the University of Warwick have created a handheld device that is designed to trace tiny magnetic particles injected into the body.

The scientists said this offers a non-toxic alternative to radioactive tracers and dyes currently used in hospitals.

Seaweed could unlock new sources of rare minerals for EVs: US study

US scientists tap seaweed for rare earths and metals used in EVs, electronics.

Researchers in the United States discovered a new way to extract rare earth minerals. They focused on seaweed, which hosts rare earth minerals in their leaf-like tissues. After multiple efforts, the Pacific Northwest National Laboratory (PNNL) research team successfully extracted critical mineral content from the seaweed biomass.

They have been growing several species in the Sequim campus and investigating different methods of extracting minerals from seaweed.
