Space stations, lunar bases, and Mars missions have moved from humans’ imagination to engineering reality. In these environments, innovation emerges through collaboration rather than isolation. Living on the moon or Mars will depend on continuous technological innovation, including on systems that extract water, generate energy and recycle waste and which can adapt to harsh and...

The Doomsday Clock shows the danger but not the way out
On January 27, the Bulletin of the Atomic Scientists moved its Doomsday Clock to 85 seconds to midnight, the closest it has been to the metaphorical point of global catastrophe. The Doomsday Clock is historically significant because it transformed the abstract, technical threat of nuclear war into a universally understood symbol of urgency. Since the...

PRIYA trial links teen B12 intake to long-term health in babies
It is known that the Indian population, particularly vegetarians, is deficient in vitamin B12. The vitamin essential for the formation of blood cells and the functioning of nerve cells is mainly found in animal-derived food. B12 deficiency during pregnancy has been associated with neural tube defects and poor foetal growth, affecting long-term health. In 1993,...

Researchers use sound waves to detect elusive helium gas leaks
Helium is famous for making balloons float, voices squeak, and as a critical resource for MRI machines and aerospace engineering. Helium is expensive and scarce, finding leaks quickly is essential, but that’s easier said than done because helium is also chemically inert and sensors, which usually rely on chemical reactors, have a tough time detecting...

Why are some stars blue, some white, some red?
– B.R. Sravan The main reason is surface temperature. Stars behave roughly as objects that absorb all incoming radiation and radiate energy back based solely on their temperature.The colour we see depends on the wavelength of light where the star emits the most energy. According to Wien’s law, hotter stars emit more energy at bluer...

To make sense of cosmic rays, CERN team tracks a fragile nucleus
The hydrogen atom is the lightest in the universe and it consists of the simplest nucleus: a single proton. But while helium is the second-lightest element, its nucleus isn’t the second simplest. That distinction belongs to the deuteron, the nucleus of the deuterium atom, which contains one proton and one neutron. (Deuterium is an isotope...
