High-precision technique stores cellular ‘memory’ in DNA

Engineers program human and bacterial cells to keep a record of complex molecular events.
Key phosphorus-based molecule for life on Earth may have come from space

Key phosphorus-based molecule for life on Earth may have come from space

The study suggests that phosphorus-based molecule of extraterrestrial origin and was delivered to Earth on the Murchison meteorite.
A random-forest, machine-learning method for identifying copy number variation from exome-sequencing data. A forest of hundreds of decision trees is trained on a validated set of genetic deletions and duplication, the model built from these trees can then be used to accurately identify copy number variation in sample exome-sequencing data.

New technique can find deletions and duplications in the human genome

Copy number variants (CNVs) are a noteworthy reason for a few genetic disorders, making their identification an essential segment of genetic analysis pipelines. Current...
The approach maps the ones the zeros of digital data to the presence or absence of particular molecules in solutions. The researchers used the scheme to encode image files in solutions.

Researchers store digital images inside molecular thumb drive

Scientists at Brown University have taken a step forward toward storing huge amounts of data in molecular storage systems. The study has shown that...
New method aims to improve match between DNA sample and face database

New method to improve match between DNA sample to a face database

While predicting what someone's face looks like based on a DNA sample remains extremely problematic, it is getting easier to filter the right face...
Harvard Medical School researchers identify new targets to inhibit viral replication and may inform the development of a new class of antiviral drugs. iStock

Catch a virus by the tail

Some RNA viruses such as Segmented negative-sense (SNS) RNA viruses initiate infection by delivering into cells a suite of genomic RNA segments, each sheathed...

Study reveals key step in cell protein production from genes

DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells,...
