Department of Energy scientists achieve fusion milestone with promising new plasma escape mechanism

fusion

In a historic moment for fusion energy, new research shows that the heat of plasma fusion is spread more evenly in tokamak reactors, suggesting new ways to improve reactor efficiency and overall lifespan while reducing the potential for damage. New findings from researchers with the US Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), … Read more

Homosexuality is common in animals So why do scientists rarely talk about it?

Same-sex sexual behavior has been observed in many non-human species around the world. It’s now a widely recognized phenomenon, but a new study suggests there’s a stark discrepancy between how common the behavior is and how often it’s reported. According to this work, researchers often see same-sex sexual behavior in the mammals they study, but … Read more

Slingshots around the sun would make a spacecraft the fastest ever

Image of the test setup for the heat shield. Credit: (2023). DOI: 10.2172/1960159 NASA is very interested in developing a propulsion method to allow spacecraft to go faster. We’ve reported several times on various ideas to support this goal, and most of the most successful ones have made good use of the sun’s gravity, usually … Read more

Features of the IS1111 and IS110 family. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-49474-9 Scientists at the University of Sydney have developed a gene-editing tool with greater precision and flexibility than the industry standard, CRISPR, which has revolutionized genetic engineering in medicine, agriculture and biotechnology. SeekRNA uses a programmable ribonucleic acid (RNA) array that can directly … Read more

JWST observations reveal a mature quasar at cosmic dawn

Artist’s impression of the bright core region of a quasar, an active galaxy. The supermassive black hole at the center is surrounded by a bright disk of gas and dust. The dust component can further obscure the view of the interior and shines primarily in the mid-infrared, light that can be analyzed by the James … Read more

One-neutron transfer can beat nuclear fusion in production, here’s the proof

3 billion microfossil puzzle can be solved with new AI deep learning model

Nuclear fusion is one of the most powerful reactions known to mankind. It is the process that powers the Sun and stars, and results in high-energy output. However, achieving nuclear fusion in laboratory environments is quite challenging as it requires extreme conditions of temperature and pressure. A new study reveals a more practical alternative to … Read more

Cognitive flexibility associated with entrepreneurial success

Summary: Habitual entrepreneurs exhibit greater cognitive flexibility and increased gray matter volume in the left insula compared to managers. This brain region is associated with divergent thinking, crucial to entrepreneurial success. The research suggests that understanding the neural basis of cognitive flexibility can improve entrepreneurial training and education. These findings highlight the importance of integrating … Read more
