Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such ...

The G-loop acts like a landing pad for additional proteins. These proteins untie the G4 knot, break apart the G-loop and ...

Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such structure, the ...

Frog egg extracts to study DNA knots To study exactly how cells untangle G4 structures, the researchers needed a system that reproduces this process outside living cells. They used protein ...

Historically, researchers focused on the role of sperm characteristics in fertilization success, but now female factors and cooperative processes are gaining recognition.

Modern humans have existed for more than 200,000 years, and each new generation has begun with a single cell—dividing, ...

While animal eggs await fertilization, their cell cycle needs to be halted. The molecule responsible for this arrest ? the cytostatic factor ? was first described in 1971. But its identity was not ...

Published in iScience, the team’s study combines biological experiments and mathematics to reveal new insights into cell migration. Alex George, Ph.D. ’24, biological sciences, and Naghmeh Akhavan, Ph ...

Talk about thinking small: researchers at Harvard University have devised a new way to implant flexible bioelectronic devices ...
