Nature has four fundamental forces: gravity, the weak force (responsible for radioactivity), electromagnetism, and the strong force. The strong force is responsible for keeping the protons and neutrons together in the nuclei of atoms. The theory describing the strong interaction between two particles is called quantum chromodynamics (QCD). In QCD, the strong force is carried...

A team led by researchers at the Johns Hopkins School of Medicine has found that several inherited traits in the mouse genome break the rules Gregor Mendel laid down in the 19th century about how genes work. This is not because the genes mutate but because of chemical modifications of the genome that can jump...

The story so far: A Bengaluru-based space company, Astrobase Space Technologies, on Friday (August 7, 2026) unveiled India’s first privately built 800 kN Full-Flow Staged Combustion (FFSC) LOX-Methane rocket engine named EVEREST. This makes India the fourth nation to have FFSC engine technology after Russia, USA and China. What are high thrust FFSC rocket engines?...

Scientists use AI to design viruses to kill hardy bacteria Scientists have used AI to design entire genomes for bacteriophages, viruses that infect and kill bacteria. Using ‘genome language models’, they generated thousands of new DNA sequences, then used them with a well-studied virus called ΦX174 as a template to yield 16 functional viruses. These...

The political scientist Claudine Gay became Harvard University’s dean of social science in 2018 and, five years later, its first Black president and only the second woman in the university’s 387-year history in the post. Later that year, on December 5, 2023, Ms. Gay testified before the U.S. House Committee on Education and the Workforce...

When a certain brilliantly-coloured butterfly, found halfway around the globe—from India to Japan—closes its wings, you cannot tell it apart from a dead leaf: the ‘dead leaf’ butterfly’s wings turn a...
