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…
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),…

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…
Activation and Support 21/06/2024 3097 view 16 like Yesterday, the first Ariane 6 rocket launched into space underwent its final ‘wet suit test’ at Europe’s Spaceport in French Guiana – it gave an exciting glimpse of what’s to come, stopping just a few seconds before starting the engine and of course, take off. First view…

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…
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…

The genes in our DNA sequence are important, helping to avoid disease or maintain overall health,…
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…
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…
