Not everything that tastes bitter is potentially harmful: But why? Study provides an explanation
ScienceDaily - Molecular Biology News
by
1d ago
A bitter taste is traditionally considered a warning sign of potentially toxic substances. But not all bitter substances are harmful. For example, some peptides and free amino acids taste bitter, even though they are non-toxic, nutritious and sometimes even vital for humans. A new study now offers an explanation for this seemingly paradoxical phenomenon ..read more

Influenza viruses can use two ways to infect cells
ScienceDaily - Molecular Biology News
by
1d ago
Most influenza viruses enter human or animal cells through specific pathways on the cells' surface. Researchers have now discovered that certain human flu viruses and avian flu viruses can also use a second entry pathway, a protein complex of the immune system, to infect cells. This ability helps the viruses infect different species -- and potentially jump between animals and humans ..read more

Genome recording makes living cells their own historians
ScienceDaily - Molecular Biology News
by
6d ago
Genomes can now be used to store information about a variety of transient biological events inside of living cells, as they happen, like a flight recorder collecting data from an aircraft. The method, called ENGRAM, aims to turn cells into their own historians. ENGRAM couples each kind of biological signal or event inside a cell to a symbolic barcode. This new strategy traces and archives the type and timing of biological signals inside the cell by inserting this information into the genome. For example, this record-keeping can track the commands that turn genes on or off ..read more

Paleolithic diets are not without risks
ScienceDaily - Molecular Biology News
by
1w ago
High-protein diets, known as 'Paleolithic diets', are popular. Using mouse models, scientists have studied their impact. While effective in regulating weight and stabilizing diabetes, these diets are not without risks. Excess protein greatly increases ammonium production, overwhelming the liver. Excess ammonium can cause neurological disorders and, in severe cases, lead to coma. These results suggest caution when following these diets ..read more

A new addition to the CRISPR toolbox: Teaching the gene scissors to detect RNA
ScienceDaily - Molecular Biology News
by
1w ago
CRISPR-Cas systems, defense systems in bacteria, have become a plentiful source of technologies for molecular diagnostics. Researchers have now expanded this extensive toolbox further. Their novel method, called PUMA, enables the detection of RNA with Cas12 nucleases, which naturally target DNA. PUMA promises a wide range of applications and high accuracy ..read more

Immune system in the spotlight
ScienceDaily - Molecular Biology News
by
1w ago
Our immune system is always on alert, detecting and eliminating pathogens and cancer cells. Cellular control mechanisms cause diseased cells to present antigens on their surface like signs for the immune system. For analysis of the necessary complex antigen processing and transport processes in real time, researchers have developed a 'cage' that is opened with light to release trapped antigens at a specific place and time ..read more
