“All work and no play makes Jack a dull boy” goes the proverb. Now, it seems no working out can also make Jack a dull boy — especially if Jack is a mouse. A team of researchers from Seoul National University and the Korea Brain Research Institute, both in South Korea, has found that aerobic...

A new study conducted during the final phase of the Chandrayaan-3 mission when the Vikram lander performed a successful hop experiment has offered fresh insights on the moon surface. The study, In Situ Temperatures, Regolith Properties, and Evidence of Erosion at Chandrayaan-3 Post-hop Location from ChaSTE Twilight Observations was conducted by a team headed by...

Elon Musk recently claimed that in three years, there will be more expert surgical robots than surgeons on the earth. The statement generated considerable excitement, speculation, and outrage in equal measure. While medicine is a deeply personal enterprise, it is also rooted in science. The fundamental challenge in surgery is not precision but adaptability. Surgery...

A: There is a major disagreement among physicists about how fast the universe is expanding. Astronomers use a value called the Hubble constant to measure it. However, the two main ways to calculate this number have produced different results. In the first method, astronomers use the cosmic distance ladder. They observe nearby objects like pulsating...

In many Indian homes, ageing unfolds quietly. A grandfather who once walked to the local market now pauses every few steps. A grandmother takes days to recover from a minor fall. Such changes are often dismissed as “normal ageing”. Medicine, however, increasingly recognises these signs as part of a condition called frailty, which is a...

From false claims that a historic lunar fly-by was staged in a movie studio to unfounded narratives that footage of the crew was AI-generated, the Artemis II mission has been clouded by a blizzard of misinformation. The falsehoods — circulating across tech platforms including X, TikTok, and Facebook — have also added fresh fuel to...

At the smallest scales, nature often repeats itself. It makes families of subatomic particles that look identical in almost every way. Yet when scientists measured them, they found these ‘copies’ didn’t line up neatly. Some are far heavier than others for no clear reason. Some change into one another at oddly chosen rates. While physicists...

A sentinel species is a species whose members’ health signals the condition of the ecosystem in which they live. Scientists monitor them because they are among the first to respond to stressors in their environment, such as pollution and disease, and their response also tends to be more apparent than most other species. In other...

Men experience more skin infections than women — doctors have known this for a while. They have proposed both behavioural and physiological reasons for this difference but the exact mechanism has been unclear. Recently, scientists at UT Southwestern Medical Centre in Texas in the U.S. reported that the male sex hormones, androgens, which include testosterone,...
