The moon’s surface is covered by ancient lava flows that are often different from those found on the earth. While volcanic rocks on the earth rarely contain more than 2% titanium dioxide (TiO2), some lunar basalts — common volcanic rocks — carry up to 18%, a fact that planetary scientists have struggled to explain for...

Evidence to support an older age for the formation of the Moon, around 4.51 billion years ago, as per a paper published in the journal Nature. This new analysis suggests that a ‘remelting’ of the Moon’s surface around 4.35 billion years ago may have masked a far older history. The Moon is thought to have been formed through...

Biotechnology graduates are the architects of the next animal science revolution in the country, experts said at a webinar on “Biotech Careers: Food and Nutrition” on Sunday (March 22, 2026). The webinar was jointly organised by the Vellore Institute of Technology, Chennai, and The Hindu as part of the series titled “Biotechnology: Role in Industry...

On March 10, a journal called Science of Climate Change published a paper calling into question the foundations of climate change. The paper concluded that after accounting for some sources of uncertainty in the climate data, the ‘correct’ changes in the oceans’ heat content and Earth’s energy imbalance are practically zero. In other words, the...

For more than a century, physicists have looked for a material that conducts electricity with zero resistance at room temperature — practical enough to transform how the world generates and uses energy. But for a long time, the highest temperature at which a material became superconducting at room pressure was -140 °C. Some other materials...

Last week, the Minor Planet Centre (MPC) announced 15 new moons had been found, four around Jupiter and 11 around Saturn. The Jovian moons were found by the U.S.-based Scott Sheppard and David Tholen and the Saturnian ones by a team led by Edward Ashton in Taiwan. The MPC is the world’s primary repository for...

From African deserts to the Arctic circle: humans spread across the planet faster and farther than any other wild vertebrate, making us outliers in the animal kingdom. While we occupy 132 million sq. km of land, a typical wild mammal occupies 165 sq. km. How did humans achieve this feat?   The answer lies in...
