Taking the temperature of a sample can be tricky—especially in the regimes of the very small and the very cold. The smaller the sample, the greater the influence the thermometer itself may exert on the measurement. And in the ultracold regime, even tiny amounts of heat can significantly alter the temperature reading.

Scientists have been studying fusion for decades with the understanding that if we could replicate the process here on Earth, we could create a virtually limitless clean power resource for the world. Fusion is the same process that happens in the stars, when two light atomic nuclei combine to form a heavier nucleus. At extremely high temperatures and pressures, hydrogen nuclei fuse together to form helium, creating enormous amounts of energy in the process. The challenge on Earth is achieving an energy output that exceeds the energy input, often referred to as Q>1. Achieving self-sustaining fusion energy requires that three conditions are achieved, referred to as the “fusion triple product,” which is the product of (1) plasma density (the number of fuel ions in a given volume), (2) confinement time (how long the hot fuel ions are kept together), and (3) plasma temperature (which provides the energy required for the fuel ions to overcome their mutual electrostatic repulsion and come close enough to fuse). 

The world’s wildlife are facing a barrage of threats caused by climate change, from the loss of suitable habitat to dwindling food supplies. As a result, endangered species across the US are edging closer to extinction at alarming rates—and if they disappear, critical genetic information could vanish with them. In a new initiative announced on October 3, the US Fish & Wildlife Service is working with the nonprofit Revive & Restore and other partners to create a “genetic library” of the country’s endangered species—before it’s too late. 

Someone waking up inside of WEST, the French tokamak located barely one kilometer away from ITER, would think they had been transported into an alien spaceship—and more specifically, into the stranded star-faring vessel in the movie Alien (1979), with its strange ribcage-like walls and dull metal vertebrae. Last week, a (perfectly awake) Newsline reporter was privileged to spend a few hours inside the machine's plasma chamber, where some of the longest plasma shots in fusion history were produced.

Firefly Aerospace, Inc., an end-to-end space transportation company, today announced it signed a multi-launch agreement with L3Harris Technologies for three dedicated launches on Firefly’s Alpha vehicle in 2026. With the capability to launch more than 1,000 kg to low Earth orbit, Firefly’s Alpha vehicle provides affordable, responsive, and reliable launch services for small satellites and spacecraft. Firefly is ramping up Alpha production at its rocket manufacturing and test site in Briggs, Texas, to support multiple government and commercial launches, while also doubling the size of its facilities to support the ongoing development of its medium launch vehicle that will first launch in 2025. The agreement further positions Firefly as the leader in small-lift launch services as the company ramps up production of its Alpha vehicle to support the growing needs of both government and commercial customers.

Aston University research has shown the way forward for making renewable hydrogen and propane fuel gases from glycerol. An organic compound, glycerol is produced mainly from fats and oils and is often used in health and beauty products. With crude glycerol from biodiesel production plants cheap and abundant the researchers have explored its potential for making hydrogen gas and biopropane - pioneering work that could benefit the environment and reduce reliance on fuel imports.

Structure-based designs are integral to advancing drug discovery, and in this regard, cryogenic electron microscopy (cryo-EM) has emerged as a pivotal tool for achieving high-resolution structures of proteins and protein complexes. Particularly noteworthy is its utility in elucidating the structures of protein classes that have historically resisted crystallization.

When it comes to battling cancer, innovation and evolution in medical technology play a vital role in improving treatment outcomes and patients' quality of life. One such innovation that has been making strides in recent years is cryotherapy for kidney cancer. Cryotherapy, also known as freezing therapy, cryosurgery, or cryoablation, is a cutting-edge procedure that harnesses the power of extreme cold to combat cancer cells effectively. This revolutionary technique is particularly promising for treating small, early-stage kidney cancers.

At a somewhat small and unassuming airport in Maribor, Slovenia, German hydrogen propulsion startup H2FLY has quietly been building up to a major milestone in zero-emission aviation over the summer. And all the hard work has come to fruition, with the successful completion of the world’s first crewed liquid hydrogen-powered flights.

Topological effects are predicted to have many potential uses in future electronic devices. Therefore, finding ways to control these effects is desirable. As predicted by first-principles calculations, the one-dimensional (1D) transition-metal trichalcogenide TaSe₃ is a strongly topological semimetal. It has a unique atomic arrangement of two inequivalent chains; the shorter distance between the Se atoms in the type-I chains (red in figures) creates strong covalent p-p bonding between the two Se atoms, whereas this bond is broken in the type-II chains (blue in figures) so that bonds form with the Ta atoms from the neighboring type-I chains. The chains are along the b-axis crystallographic direction. Calculations suggest that nontrivial topological phases can be induced by the distorted type-II chain under ambient conditions and/or strain. In collaboration with John Singleton at the Pulsed-Field Facility, National High Magnetic Field Laboratory, research led by Dr. Rongying Jin of the University of South Carolina (USC) investigated the effect of strain on TaSe₃ by measuring its magnetoresistance (MR) in fields of up to 60 T. Both ribbon-shaped (under ambient conditions) and ring-shaped (i.e., deliberately strained) samples were studied.
