Twisting, flexible crystals key to solar energy production

Posted by in categories: chemistry, solar power, sustainability

Researchers at Duke University have revealed long-hidden molecular dynamics that provide desirable properties for solar energy and heat energy applications to an exciting class of materials called halide perovskites.

A key contributor to how these materials create and transport electricity literally hinges on the way their atomic lattice twists and turns in a hinge-like fashion. The results will help materials scientists in their quest to tailor the chemical recipes of these materials for a wide range of applications in an environmentally friendly way.

The results appear online March 15 in the journal Nature Materials.

Researchers Spotted Malware Written in Nim Programming Language

Posted by in category: cybercrime/malcode

Cybersecurity researchers have unwrapped an “interesting email campaign” undertaken by a threat actor that has taken to distributing a new malware written in Nim programming language.

Dubbed “NimzaLoader” by Proofpoint researchers, the development marks one of the rare instances of Nim malware discovered in the threat landscape.

“Malware developers may choose to use a rare programming language to avoid detection, as reverse engineers may not be familiar with Nim’s implementation, or focused on developing detection for it, and therefore tools and sandboxes may struggle to analyze samples of it,” the researchers said.

The realization of a new type of information demon that profits from gambling strategies

Posted by in category: physics

Researchers at the International Centre for Theoretical Physics (ICTP) in Italy and the PICO group at Aalto University in Finland have introduced the idea of an information demon that follows a customary gambling strategy to stop non-equilibrium processes at stochastic times. The new demons they realized, which differ from the renowned Maxwell’s demon, were presented in a paper published in Physical Review Letters.

“Our research was driven by curiosity,” Gonzalo Manzano, one of the researchers who carried out the study, told Phys.org. “We asked ourselves about the implications of processes whose fluctuations fulfill (or break) some strong properties of stochastic processes on the link between thermodynamics and information.”

The recent study by Gonzalo Manzano, Edgar Roldan and their colleagues is based on previous works investigating the link between information and thermodynamics at the stochastic level. It also draws inspiration from recent research that explored the properties of a unique family of stochastic processes known as martingales in the context of thermodynamics.

Scientists plumb the depths of the world’s tallest geyser

Posted by in category: futurism

When Steamboat Geyser, the world’s tallest, started erupting again in 2018 in Yellowstone National Park after decades of relative silence, it raised a few tantalizing scientific questions. Why is it so tall? Why is it erupting again now? And what can we learn about it before it goes quiet again?

The University of Utah has been studying the geology and seismology of Yellowstone and its unique features for decades, so U scientists were ready to jump at the opportunity to get an unprecedented look at the workings of Steamboat Geyser. Their findings provide a picture of the depth of the as well as a redefinition of a long-assumed relationship between the geyser and a nearby spring. The findings are published in the Journal of Geophysical Research-Solid Earth.

“We scientists don’t really know what controls a geyser from erupting regularly, like Old Faithful, versus irregularly, like Steamboat,” says Fan-Chi Lin, an associate professor with the Department of Geology and Geophysics. “The subsurface plumbing structure likely controls the eruption characteristics for a geyser. This is the first time we were able to image a geyser’s plumbing structure down to more than 325 feet (100 m) deep.”

After Sunday’s launch, SpaceX is on the cusp of a historic reuse milestone

Posted by in categories: Elon Musk, space travel

“For those that know rockets, this is a ridiculously hard thing.”


As this is the first Falcon 9 rocket to launch nine missions, it raises the prospect of a first stage making a tenth flight in the near future, probably within a month or two. Reaching ten flights would accomplish one of the main goals set by SpaceX with the Falcon 9 rocket, after optimizing the vehicle for reuse about three years ago.

The company debuted its “Block 5” version of the Falcon 9 rocket in May 2018, and since then this vehicle has flown 55 missions, all of which have successfully delivered their payloads to orbit. More importantly, the changes SpaceX engineers incorporated into this new rocket to ensure its robustness for reuse, such as strengthening its “Octaweb” engine bay, have largely been validated.

Sherpa raises $8.5M to expand from conversational AI to B2B privacy-first federated learning services

Posted by in categories: biotech/medical, health, robotics/AI

Sherpa, a startup from Bilbao, Spain that was an early mover in building a voice-based digital assistant and predictive search for Spanish-speaking audiences, has raised some more funding to double down on a newer focus for the startup: building out privacy-first AI services for enterprise customers.

The company has closed $8.5 million, funding that Xabi Uribe-Etxebarria, Sherpa’s founder and CEO, said it will be using to continue building out a privacy-focused machine learning platform based on a federated learning model alongside its existing conversational AI and search services. Early users of the service have included the Spanish public health services, which were using the platform to analyse information about COVID-19 cases to predict demand and capacity in emergency rooms around the country.

World’s first remote tattoo is completed by a robotic arm

Posted by in categories: internet, robotics/AI

The world’s first remote tattoo was completed by a 5G-powered robotic arm fitted with a tiny needle.

Tattoo artist Wes Thomas drew the design on a mannequin arm while a robot in another location copied his motions on Dutch actress Stijn Fransen’s wrist.

A concept from physics called negentropy could help your life run smoother

Posted by in categories: energy, physics

In physics, entropy is the process of a system losing energy and dissolving into chaos. This applies to social systems in everyday life, too. Limiting energy loss can make social systems run better.

Starship SN11 prepares to fly as SpaceX pushes for Orbital flight this summer

Posted by in category: space travel

Starship SN11 will re-attempt a Static Fire test Tuesday – following a scrub on Monday – ahead of a potential flight later this week. Forever subject to change due to numerous considerations – ranging from weather, hardware parameters, and paperwork approval – SN11 will mark the final test of this iteration of Starship before the program moves into the next phase of testing.

Following SN11’s flight, SpaceX will move on to SN15, 16, and 17, alongside testing with Super Heavy prototypes BN1 and BN2, before shooting for an orbital launch with SN20 and BN3. In typical SpaceX-style, that orbital launch has an astonishing – and unlikely – “by July 1” target. At the very least, this target portrays SpaceX’s Starship drive to push the vehicle into operation. SN11:
