Planarian flatworms are small, unassuming creatures with an astonishing talent. Cut one into pieces, and each fragment can regrow a complete animal. This seemingly magical ability comes from their prolific stem cells, known as neoblasts, which can produce every tissue in the body. In most animals, such regenerative stem cells grow under the care of...

National Mathematics Day and the double life of Jantar Mantar
Commemorating December 22 as National Mathematics Day invites memories of biographies, theorems, institutes, and prizes. But India also has mathematical places: built environments that render the mathematical act of measurement public. Jantar Mantar in New Delhi is one of them. It was commissioned by Sawai Jai Singh II and completed in 1724 as an architectural...
Why do students fear math? | National Mathematics Day
For many students, mathematics feels less like a subject and more like a verdict, you’re either “good at it” or you’re not. There’s no escape from maths in school, and for some, every class brings a familiar knot of anxiety rather than curiosity or confidence. You’re not imagining it: the fear is real, and it’s...
NASA loses contact with MAVEN, which reached Mars with Mangalyaan
NASA has lost contact with its Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft, the Mars orbiter that has worked for more than a decade to study how the planet’s atmosphere is escaping into space. The spacecraft went silent in early December and engineers are still trying to re-establish communication. MAVEN’s job at Mars has been...
Southern Ocean carbon ‘anomaly’ reveals what models can still miss
The chilly waters of the Southern Ocean that surround Antarctica like a moat are among the least explored and least understood of all the world’s oceans. This is stark because we also know that this ocean plays an outsized role in regulating the earth’s climate with its moody currents and its tremendous ability to absorb...
What is a superkilonova?
A: A superkilonova is a rare kind of cosmic explosion. When two neutron stars smash into each other, the material tossed into space includes heavy, radioactive elements like gold, platinum, and neodymium. Over time the elements decay and the emissions in the optical and infrared parts of the spectrum are called a kilonova. A superkilonova...

Study finds normalising blood glucose with lifestyle could halve heart disease risk in prediabetics
Bringing blood glucose to normal range through lifestyle changes could halve the risk of heart attack, heart failure and premature death among prediabetics, according to a study. Findings published in ‘The Lancet Diabetes and Endocrinology’ journal show that remission of prediabetes — achieving normal blood glucose levels — may establish a new, measurable target for...
Will new Act aid India’s nuclear development? | Explained
The story so far: Parliament has brought into force the Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India (SHANTI) Act which repeals legislation that governs nuclear activity — the Atomic Energy Act, 1962, and Civil Liability for Nuclear Damage (CLND) Act, 2010. Why is SHANTI significant? SHANTI encourages private companies to participate and...
