SAR11 bacteria dominate the world’s oceans by being incredibly efficient, shedding genes to survive in nutrient-poor waters. But that extreme streamlining appears to backfire when conditions change.

One of the greatest mysteries of our planet is how a soup of lifeless chemicals transformed into the first living cell. There are several competing theories about where this happened, from frozen ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

Here are strategic revision techniques, important topics, diagram practice, and exam-day strategies to help CBSE Class 12 ...

Life may have begun when RNA molecules began to replicate themselves, and now we’ve finally found an RNA molecule that is very close to being able to do this ...

A group of ocean bacteria long considered perfectly adapted to life in nutrient-poor waters may be more vulnerable to environmental change than scientists realized. The bacteria, known as SAR11, ...

By FY25, RollsKing closed at ₹85 crore in gross revenue. A month before FY26 wrapped, the group crossed ₹100 crore.Rolling Fresh now accounts for roughly 20% of total revenue--nearly ₹20 crore on its ...

One of the most abundant living organisms on Earth may also be one of the most vulnerable. A group of ocean bacteria known as ...

Ultimately, the gel-first hypothesis does not claim to provide a definitive answer to the origin of life. Rather, it offers a conceptual framework—one that integrates soft-matter physics, systems ...

To store heat for days, weeks, or months, you need to trap the energy in the bonds of a molecule that can later release heat on demand. The approach to this particular chemistry problem is called ...
