One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published in Nature. Chromosomes are thread-like structures that carry a cell's ...

CDT1 inhibits the helicase activity of the MCM complex, thereby suppressing nascent strand synthesis in DNA replication in cultured human cells. This action results in fork collapse and DNA damage, ...

Cornell (NY, USA) researchers have found that a new DNA sequencing technology can be used to study how transposons move within and bind to the genome. Transposons play critical roles in immune ...

A new mathematical model of a wormhole suggests that two black holes can be “cut and pasted.” Cut and paste is an official concept in math, referring to two surfaces that may be transposable. In this ...

Johns Hopkins University School of Medicine alumnus and former faculty member Hamilton O. Smith, whose 1978 Nobel Prize-winning discovery of restriction enzymes revolutionized genetic engineering, ...

As a graduate student at the University of California, Berkeley, Mark Levin started sketching out ideas for how to do something no chemist had ever managed before: swapping one of the carbon atoms in ...

Leave your assumptions about prints and photographs behind. In this exhibition, flat surfaces expand outward. Images aren’t simply printed—they are worked, reworked, and then reworked again. Paper ...

The 125th U.S. Open is living up to its longtime reputation. It's often considered the toughest major in golf and Oakmont Country Club, the site of more U.S. Open tournaments than any other venue, is ...

A rumor that circulated online in May 2025 claimed Britain's Princess Beatrice, the elder daughter of Prince Andrew and his ex-wife, Sarah, Duchess of York, cut ties with the British royal family ...

This valuable descriptive manuscript builds on prior research showing that the elimination of Origin Recognition Complex (ORC) subunits does not halt DNA replication. The authors obtain solid data ...

The discovery of DNA ligase by the Gellert, Lehman, Richardson, and Hurwitz teams in 1967 was a breakthrough in molecular biology. These essential enzymes maintain genome integrity and play a vital ...
