Nanofluidics sorts DNA for cancer research

(Phys.org) -- Cornell nanotechnology researchers have devised a new tool to study epigenetic changes in DNA that can cause cancer and other diseases: a nanoscale fluidic device that sorts and collects DNA, one molecule at ...

How epigenetic switches control gene expression

Scientists at Tokyo Institute of Technology have deciphered how to quantitatively assess the effects of specific epigenetic changes on the rate of transcription by developing a mathematical model. Using their method, they ...

Revolutionary process could signal new era for gene synthesis

A team of scientists led by the University of Southampton has demonstrated a groundbreaking new method of gene synthesis - a vital research tool with real-world applications in everything from growing transplantable organs ...

A review article clarifies genotype-independent plant transformation

Recently, researchers from North Carolina State University and the Beltsville Agricultural Research Center published the first review of research progress on genotype-independent plant transformation. In this review, researchers ...

Controlling genes with light

Although human cells have an estimated 20,000 genes, only a fraction of those are turned on at any given time, depending on the cell's needs—which can change by the minute or hour. To find out what those genes are doing, ...

Baby cells learn to communicate using the lsd1 gene

We would not expect a baby to join a team or participate in social situations that require sophisticated communication. Yet, most developmental biologists have assumed that young cells, only recently born from stem cells ...

Epigenetic 'switch' regulates RNA-protein interactions

Chemical changes - also known as epigenetic modifications - to messenger RNA (mRNA) are thought to play an important role in gene expression, and have recently been found to affect biological processes such as circadian clock ...
