Researchers have made significant advancements in understanding atomic-scale heat motion in materials, crucial for developing solid-state cooling technology.

This technology, which operates without traditional refrigerants or moving parts, uses materials like nickel-cobalt-manganese-indium magnetic shape-memory alloys to exploit the magnetocaloric effect for efficient cooling.

A crucial knowledge gap in atomic-scale heat motion was recently bridged by a research team led by the Department of Energy’s Oak Ridge National Laboratory. This new understanding holds promise for enhancing materials to advance an emerging technology called solid-state cooling.

New research has established a reversible framework for quantum entanglement, aligning it with the principles of thermodynamics and paving the way for improved manipulation and understanding of quantum resources.

Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lami from the University of Amsterdam have demonstrated through probabilistic calculations the existence of an “entropy” rule for quantum entanglement. This discovery could enhance our understanding of quantum entanglement, a crucial resource underpinning the potential of future quantum computers. Although quantum entanglement has been a research focus in quantum information science for decades, optimal methods for its effective utilization remain largely unknown.

The second law of thermodynamics, which says that a system can never move to a state with lower “entropy”, or order, is one of the most fundamental laws of nature and lies at the very heart of physics. It is what creates the “arrow of time,” and tells us the remarkable fact that the dynamics of general physical systems, even extremely complex ones such as gases or black holes, are encapsulated by a single function, its “entropy.”

New research has revealed that the lag observed in organic electrochemical transistors (OECTs) when switched on is due to a two-step activation process, providing crucial insights for designing more effective and customizable OECTs for various technological and biological applications.

Researchers who want to bridge the divide between biology and technology spend a lot of time thinking about translating between the two different “languages” of those realms.

“Our digital technology operates through a series of electronic on-off switches that control the flow of current and voltage,” said Rajiv Giridharagopal, a research scientist at the University of Washington. “But our bodies operate on chemistry. In our brains, neurons propagate signals electrochemically, by moving ions — charged atoms or molecules — not electrons.”

A naturally occurring sugar called 2-deoxy-D-ribose (2dDR) may boost hair growth.

Did life ever exist on Mars, and if so, how did it get there? This is the goal of NASA’s Curiosity rover, which has traversed Gale Crater on Mars since 2012. But a recent finding by the car-sized robotic explorer could help bring scientists one step closer to answering these questions as Curiosity sent back images of yellow crystals revealed to be deposits of elemental sulfur, along with an entire field of them. This finding was accidentally “un-earthed” as Curiosity drove over them during its excursions. While scientists didn’t anticipate finding elemental sulfur in this region, this finding could hold the potential to help piece together the geologic history of Gale Crater and whether life once existed there.

“Finding a field of stones made of pure sulfur is like finding an oasis in the desert,” said Dr. Ashwin Vasavada, who is a project scientist on Curiosity at NASA’s Jet Propulsion Laboratory. “It shouldn’t be there, so now we have to explain it. Discovering strange and unexpected things is what makes planetary exploration so exciting.”

The fighter’s new engines can power laser weapons and enable a “pilot optional” mode.

How many Earth-like planets exist throughout the universe? This is what recent talk given at the National Astronomy Meeting 2024 hopes to address as Dr. David Brown, who is a scientist on the European Space Agency’s (ESA) PLATO (PLAnetary Transits and Oscillations of stars) mission, provided an update on the mission and the goals it hopes to achieve. This comes as PLATO is currently scheduled to launch in December 2026 with the goal of finding Earth-like planets throughout the universe, which could greatly expand our knowledge of exoplanets, as well.

“PLATO’s goal is to search for exoplanets around stars similar to the Sun and at orbital periods long enough for them to be in the habitable zone,” said Dr. Brown. “One of the main mission objectives is to find another Earth-Sun equivalent pair, but it is also designed to carefully and precisely characterize the exoplanets that it finds (i.e. work out their masses, radii, and bulk density).”
