Building Better Neural Networks

Blog

Given the brain's complexity, it's no surprise that deep neural networks (DNN), computing system based on the brain, are challenging to design and improve. That is a challenge that companies like DarwinAI are meeting head-on. We talked to Sheldon Fernandez, DarwinAI’s CEO, to find out more.

Gram Positive vs Gram Negative

Article

Being able to differentiate bacterial species is important for a host of reasons. Whilst molecular techniques can determine the specific species, even without getting into the molecular nitty gritty, there are phenotypic differences between groups of bacteria that can be used to differentiate them. One such useful classification – if a bacterium is Gram positive or Gram negative - is based on the structure of bacterial cell walls.

Identifying Novel Opioid Agonists From Metabolites

Blog

Novel drugs of abuse have been a growing problem for law enforcement and the medical profession. Consequently, they have also become a challenge for analysts in the face of new or variant chemicals. We spoke to Research Scientist Alex Krotulski about the work he is doing to identify new and emerging illicit substances

Ketone Bodies Help Maintain a Large Pool of Adult Intestinal Stem Cells
News

Researchers at MIT have discovered an unexpected finding of consuming a ketogenic diet. Ketone bodies are known to activate signaling pathways implicated in stem cell differentiation. In a mouse model, they have shown that high levels of ketone bodies help the intestine to maintain a large pool of adult stem cells. These stem cells contribute to keeping the lining of the intestine healthy.

Low-nicotine Gene-edited Tobacco Could Combat Nicotine Addiction — But Not in Europe

Article

The applications of CRISPR mediated genome editing are continuing to grow. The number of individuals addicted to nicotine is also continuing to grow. The solution? CRISPR-edited nicotine-free tobacco plants, say researchers Felix Stehle and Julia Schachtsiek from the Technical University of Dortmund in Germany.

The Genetics of Neurodegeneration With Professor John Hardy
Article

At the British Neuroscience Association (BNA)’s Festival of Neuroscience in April 2019, we were lucky enough to sit down with some influential neuroscientists to discuss their work. Here we interview University College London’s John Hardy, whose work into the genetics of neurodegenerative disorders saw him share the Brain Prize in 2018.

Transcription vs Translation Worksheet
Article

The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation. Here, we describe the processes of transcription and translation as they take place in eukaryotic cells.

Knowledge Really Is Power When It Comes to Investigating the Mechanisms of Microbes
Article

For scientists investigating genomes and molecular mechanisms of microbes, it is vital that they can collate existing knowledge and understanding in the context of their current work to draw conclusions and fill gaps in knowledge. We spoke to Dr Peter Karp, leader of the BioCyc project, a microbial genomes and metabolic pathways web portal, about the evolution of BioCyc and its role in research.
