Protecting the genome from transposon activation

Transposons are foreign DNA elements capable of random insertion into the genome, an event that can be very dangerous for a cell. Their activity must be silenced to maintain genomic integrity, which is primarily achieved ...

High-speed model for the fight against SARS-CoV2

To contain the SARS-CoV2 coronavirus and slow the spread of infections and the rising death toll, researchers and health professionals around the world are rapidly developing vaccines and medical drugs. But before these can ...

Peering under the hood of SARS-CoV-2

Information from electron microscope images and protein databases has been used to develop a detailed 3D model of SARS-CoV-2, which can be readily updated as new data becomes available. The modeling tool has potential for ...

Cells transform themselves in male worms to improve mating

A cell in worms that transforms itself into a completely different type of cell when males mature, to play a key role in mating behavior, has been recently discovered by a team led by UCL researchers. The researchers say ...

Model organism

A model organism is a species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the organism model will provide insight into the workings of other organisms. In particular, model organisms are widely used to explore potential causes and treatments for human disease when human experimentation would be unfeasible or unethical. This strategy is made possible by the common descent of all living organisms, and the conservation of metabolic and developmental pathways and genetic material over the course of evolution. Studying model organisms can be informative, but care must be taken when generalizing from one organism to another.
