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 ...

SAR11 bacteria dominate the world’s oceans by being incredibly efficient, shedding genes to survive in nutrient-poor waters.

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 ...

Abstract Cancer cells precisely modulate replication stress to sustain genomic instability without triggering lethal DNA damage, yet regulators ...

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 ...

Genomic analysis shows SAR11 bacteria, adapted to low-nutrient oceans, lack key cell cycle controls. As conditions change, ...

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

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, ...

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 ...

Leadership Excellence As global competition intensifies, mid-sized cities with specialized strengths are emerging as critical ...

In over 3,000 women, menstrual blood collected with a minipad detected high-grade cervical lesions with sensitivity similar to clinician HPV tests. The non-invasive approach could expand screening ...
