Distant quasar J0439+1634 explored in X-rays
Using ESA's XMM-Newton spacecraft, an international team of astronomers has conducted X-ray observations of the most distant known gravitationally lensed quasar—J0439+1634. Results of the study, published December 20 on the arXiv pre-print server,.....»»
Researchers use muonic X-rays to find elemental makeup of samples without damaging them
By combining technologies originally designed for high-energy particle accelerators and astronomy observations, researchers can now for the first time analyze the elemental makeup of samples without damaging them, which could be useful for researcher.....»»
DNA nanostructures for targeting cellular surface receptors
A broad subset of parameters, which include cell signaling modulation and receptor binding efficiency, can be explored using programmable DNA nanostructures. Glenn Cremers shows how these structures can uncover important cell signaling mechanisms, pr.....»»
Challenges development teams face when building applications with open source
Tidelift released a report providing critical insights into the state and practice of open source software supply chain management. This comprehensive study of nearly 700 technologists, now in its fourth year, explored the most urgent challenges deve.....»»
Inspired by prehistoric creatures, researchers make record-setting lenses
Five hundred million years ago, the oceans teemed with trillions of trilobites—creatures that were distant cousins of horseshoe crabs. All trilobites had a wide range of vision, thanks to compound eyes—single eyes composed of tens to thousands o.....»»
Building a better spacesuit
It's been 50 years since humans first walked on the moon. Since then, astronauts have primarily explored low Earth orbit. Now that NASA is preparing to return to the moon, experts are reevaluating the practicality of the spacesuit......»»
From cell fat to cell fate
How does a cell "decide" what type of cell to become? The question of "cell fate" has been explored for decades now, especially in the context of stem cell biology, but there are still gaps in our understanding. For example, any multicellular organis.....»»
Mars rover spots gusty weather blowing across the Martian desert
Martian weather is awfully dusty.A camera aboard NASA's Mars Curiosity rover — a car-sized robot that's explored the planet for nearly a decade — recently spotted a dusty wind gust blowing over the red desert.You can see the weather in th.....»»

Growth-climate sensitivity of two pine species varies with site-specific environmental conditions
A better understanding of tree growth-climate sensitivity across regions and species may reduce uncertainties in simulating forest carbon budgets. However, few studies have explored the growth-climate sensitivity of different tree species in Southwes.....»»
EU Clears First Autonomous X-Ray-Analyzing AI
An artificial intelligence tool that reads chest X-rays without oversight from a radiologist got regulatory clearance in the European Union last week -- a first for a fully autonomous medical imaging AI, the company, called Oxipit, said in a statemen.....»»

Nanomaterials: Light dependent atom clusters for sensing applications
In a new report now published in Nature Asia Materials, Kenshi Harada and a team in materials science and analytical science in Japan and France formed a new environment sensing device that explored the opto-ionic-electronic phenomena of an octahedr.....»»
X-rays help scientists use designer DNA to uncover new forms of material
A research team led by Northwestern University and the University of Michigan has developed a new method for assembling particles into colloidal crystals, a valuable type of material used for chemical and biological sensing and light-detecting device.....»»
Hubble Sees Most Distant Star Ever, 28 Billion Light-Years Away
The Hubble Space Telescope has glimpsed the most distant single star it's ever observed, glimmering 28 billion light-years away. And the star could be between 50 to 500 times more massive than our sun, and millions of times brighter. From a report: I.....»»
Upload depicts economic inequality in the digital afterlife
The digital afterlife has been explored in many TV shows, but none in such a clever, satirical, and cynical way as in Amazon Prime Video's Upload......»»
Hubble picks up the most distant star yet observed

Scientists discover distant long-period comets quickly fade away
As comets approach the Sun, they release gas and dust known to astronomers as cometary activity. For comets passing near or inside Earth's orbit, this activity slows over successive orbits. University of Oklahoma astronomer Nathan Kaib has found this.....»»
Wistron"s Wifundity robots adopt modular design for better environment
A typical day of Wifundity autonomous mobile robots (AMR) starts at dusk, when office workers have gone home to their families. In the dark office buildings, the UV disinfecting robots go down the aisles, beaming UV rays in all directions to kill ger.....»»
