NewsNew study uncovers key differences in allosteric regulation of cAMP receptor proteins in bacteria
A new study provides key insights into how bacterial cAMP receptor proteins (CRPs) respond differently to the ubiquitous signaling molecule, cyclic AMP (cAMP), challenging the assumption that structural similarity predicts functional behavior in allosteric proteins.

NewsResearchers in Brazil discover a gene that may afford protection against COVID-19
During the pandemic, health worker Maria Tereza Malheiros Sapienza’s curiosity was aroused by her immunity to SARS-CoV-2, even though her husband was infected twice. A new study reveals that an overexpression of IFIT3 protein was responsible.

NewsThe secret ‘sex lives’ of bacteria: Study challenges old ideas about how species form
Researchers discovered that microbial species form and maintain their distinct identities through unique way of genetic material exchange, especially via homologous recombination, apart from the common asexual reproductive method.

NewsLooking to Kenya’s Lake Victoria for what may come for Lake Erie
Scientists conducted a genetic survey on cyanobacteria in the Winam Gulf of Kenya’s Lake Victoria, which serves as a model for the cyanobacterial harmful algal blooms (cyanHABs) in Lake Erie under the warming climate.

NewsBacterial toxin offers hope to tackle soybean nematode pest
A new study reveals how genetically equipping soybean plants with bacterial toxin Cry14 could revolutionize the fight against the microscopic soybean cyst nematode. This approach has been implemented successfully to prevent SCN from feeding on soybean roots.

NewsScientists implicate a novel cellular protein in hepatitis A infection
Viruses have thrived in humans for tens of thousands of years, evolving to take advantage of the machinery of cells to replicate and survive inside us. Some can slip past our defenses and invade without even causing symptoms. Source: Shirasaki et al. (2024) (Left) Liver cells infected with ...

NewsAncient viral DNA in human genome linked to multiple sclerosis and amyotrophic lateral sclerosis
New research has revealed a connection between ancient viral DNA embedded in the human genome and the genetic risk for two major diseases that affect the central nervous system.

NewsBacterial ‘flipping’ allows genes to assume different forms
A new study has shown that inversions, which cause a physical flip of a segment of DNA and change an organism’s genetic identity, can occur within a single gene, challenging a central dogma of biology — that one gene can code for only one protein.

NewsDeeper corals may help shallow reefs recover in the Florida keys
Using the blushing coral star (Stephanocoenia intersepta), found throughout the Western Atlantic, researchers have investigated how coral populations at different depths and locations may be related or ‘connected’ to each other.
