A research team led by Prof. Guo Bin from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has designed and optimized an organic Rankine cycle (ORC) system specifically for recovering low-grade waste heat from the steady-state Chinese Fusion Engineering Testing Reactor (CFETR) based on organic fluid R245fa, achieving enhanced thermal efficiency and reduced heat loss.
CFETR, a steady-state magnetic fusion reactor, is a crucial step toward realizing commercial fusion energy. However, managing the large amount of low-grade waste heat produced by components such as the divertor and blanket remains a key challenge.
To solve the thermodynamic and heat integration issues, the researchers developed advanced simulation models using Engineering Equation Solver for cycle analysis and MATLAB-based LAMP modeling for dynamic system configuration. These tools enabled a comprehensive investigation and optimization of the ORC configuration, leading to significantly improved thermal performance.
A newly discovered Linux malware, which has evaded detection for over a year, allows attackers to gain persistent SSH access and bypass authentication on compromised systems.
Nextron Systems security researchers, who identified the malware and dubbed it “Plague,” describe it as a malicious Pluggable Authentication Module (PAM) that uses layered obfuscation techniques and environment tampering to avoid detection by traditional security tools.
This malware features anti-debugging capabilities to thwart analysis and reverse engineering attempts, string obfuscation to make detection more difficult, hardcoded passwords for covert access, as well as the ability to hide session artifacts that would normally reveal the attacker’s activity on infected devices.

A team of international researchers led by King Abdullah University of Science and Technology (KAUST) and including researchers from King Abdulaziz City for Science and Technology (KACST) has developed a new composite material that enhances the performance of solar cells. Solar cells with the material functioning for weeks in the Saudi Arabia desert showed higher power output and a longer operation time than solar cells without. Additionally, the material is cheap to fabricate and reduces the cost of maintaining solar cells. The study can be read in Materials Science and Engineering.
Composite material keeps solar cells cool using air moisture and no electricity to extend solar cell lifetime more than 200%.
Carl David Anderson was born in New York City, the son of Swedish immigrants. He studied physics and engineering at Caltech (B.S., 1927; Ph. D., 1930). Under the supervision of Robert Millikan, He began investigations into cosmic rays during the course of which he encountered unexpected particle tracks in his (modern versions now commonly referred to as an Anderson) cloud chamber photographs that he correctly interpreted as having been created by a particle with the same mass as the electron, but with opposite electrical charge. This discovery, announced in 1932 and later confirmed by others, validated Paul Dirac’s theoretical prediction of the existence of the positron. Anderson first detected the particles in cosmic rays. He then produced more conclusive proof by shooting gamma rays produced by the natural radioactive nuclide ThC’’ (208 Tl) [ 2 ] into other materials, resulting in the creation of positron-electron pairs. For this work, Anderson shared the 1936 Nobel Prize in Physics with Victor Hess. [ 3 ] Fifty years later, Anderson acknowledged that his discovery was inspired by the work of his Caltech classmate Chung-Yao Chao, whose research formed the foundation from which much of Anderson’s work developed but was not credited at the time. [ 4 ]
Also in 1936, Anderson and his first graduate student, Seth Neddermeyer, discovered a muon (or ‘mu-meson’, as it was known for many years), a subatomic particle 207 times more massive than the electron, but with the same negative electric charge and spin 1/2 as the electron, again in cosmic rays. Anderson and Neddermeyer at first believed that they had seen a pion, a particle which Hideki Yukawa had postulated in his theory of the strong interaction. When it became clear that what Anderson had seen was not the pion, the physicist I. I. Rabi, puzzled as to how the unexpected discovery could fit into any logical scheme of particle physics, quizzically asked “Who ordered that?” (sometimes the story goes that he was dining with colleagues at a Chinese restaurant at the time). The muon was the first of a long list of subatomic particles whose discovery initially baffled theoreticians who could not make the confusing “zoo” fit into some tidy conceptual scheme.
3D Systems is collaborating with researchers from Penn State University and Arizona State University on two projects sponsored by NASA intended to enable groundbreaking alternatives to current thermal management solutions.
Severe temperature fluctuations in space can damage sensitive spacecraft components, resulting in mission failure. By combining deep applications expertise with 3D Systems’ leading additive manufacturing solutions comprising Direct Metal Printing (DMP) technology and tailored materials and Oqton’s 3DXpert® software, the teams are engineering sophisticated thermal management solutions for the demands of next-generation satellites and space exploration.
The project led by researchers with Penn State University, Arizona State University, and the NASA Glenn Research Center in collaboration with 3D Systems’ Application Innovation Group (AIG) has resulted in processes to build embedded high-temperature passive heat pipes in heat rejection radiators that are additively manufactured in titanium. These heat pipe radiators are 50 percent lighter per area with increased operating temperatures compared with current state-of-the-art radiators, allowing them to radiate heat more efficiently for high-power systems.

Scientists at Columbia Engineering have developed an injectable hydrogel made from yogurt-derived extracellular vesicles (EVs) that could revolutionize regenerative medicine. These EVs serve both as healing agents and as structural components, eliminating the need for added chemicals. The innovation leverages everyday dairy products like yogurt to create a biocompatible material that mimics natural tissue and enhances healing.
Johns Hopkins University researchers have grown a novel whole-brain organoid, complete with neural tissues and rudimentary blood vessels—an advance that could usher in a new era of research into neuropsychiatric disorders such as autism.
“We’ve made the next generation of brain organoids,” said senior author Annie Kathuria, an assistant professor in JHU’s Department of Biomedical Engineering who studies brain development and neuropsychiatric disorders. “Most brain organoids that you see in papers are one brain region, like the cortex or the hindbrain or midbrain. We’ve grown a rudimentary whole-brain organoid; we call it the multi-region brain organoid (MRBO).”
The research, published in Advanced Science, marks one of the first times scientists have been able to generate an organoid with tissues from each region of the brain connected and acting in concert. Having a human cell-based model of the brain will open possibilities for studying schizophrenia, autism, and other neurological diseases that affect the whole brain—work that typically is conducted in animal models.
