It might look like a comet or a shooting star, but this time-lapse video is actually a tiny plant root, not much thicker than a human hair, magnified hundreds of times as it grows under the microscope.
Tinkerer though he is, Peter Dahlberg did not spend the last few years tearing apart a $1.5 million microscope just for fun.
Researchers led by Prof. Gan Haiyun from the Shenzhen Institute of Advanced Technology (SIAT) of the Chinese Academy of Sciences (CAS) have documented the parental histones inheritance safeguard mechanism, in which parental ...
Every time a stem cell divides, one daughter cell remains a stem cell while the other takes off on its own developmental journey. But both daughter cells require specific and different cellular materials to fulfill their ...
A study of the relationship between the growth rate of tropical trees and the frequency of genetic mutations they accumulate suggests that older, long-lived trees play a greater role in generating and maintaining genetic ...
Ribosomal DNA (rDNA) sequences are essential parts of many species' genomes. The highly repetitive nature of these DNA sequences makes them susceptible to shrinkage over time—and if they shrink too much, cells die. If rDNA ...
Creating artificial cells with life-like characteristics out of a minimal set of components is a major goal of synthetic biology. Autonomous motion is a key capability here, and one that is difficult to reproduce in the test ...
What seems like a straightforward task for a cell—dividing in two—is actually an intricate series of engineering puzzles. A dividing cell needs to maneuver its insides so that the right components will end up in each ...
EPFL researchers have used a nanoplasmonics approach to observe the real-time production of cell secretions, including proteins and antibodies; an advancement that could aid in the development of cancer treatments, vaccines, ...
In a collaborative paper in published in the Proceedings of the National Academy of Sciences, Yves Barral with Jorrit Enserink and the Pierre Chymkowitch group in Norway show that the effects on transcription of chromosome ...
