Feb 16 2024Marine Biological Laboratory But in some situations, such as inside elevators or within the candy-colored bacterial structures known as "pink berries," staying apart just isn't feasible.
Like all organisms, these cooperative microbes risk contracting viruses from their environment. Pink berries and other multicellular bacteria have a heightened need for protection, since -; like us -; they are composed of genetically similar cells packed tightly together, with no social distancing possible.Through her collaborator Blair Paul, assistant scientist at MBL, Wilbanks learned about an unusual genetic mechanism that they found to be abundant within Thiohalocapsa.
All living organisms need to detect threats they have never encountered before. Humans and other vertebrates solve this problem by shuffling and mutating genes for their sensor proteins to generate a diverse army of sentinels. Though recent research has shown many components of our innate immune systems evolved from bacterial ancestors, scientists have never before seen in bacteria anything like our hyper-diverse antibodies.

What can bulls tell us about men? Genetic discovery could translate to human fertility researchInfertility is a widespread problem: worldwide, one in eight couples fail to fulfill their desire to have children within a year—or even at all. In half the cases, this is due to fertility disorders that stem from the male. However, it is difficult to identify the genetic causes of such fertility disorders in humans.

Heartbroken mum told her daughter won't live to see her twentiesA mum has shared her heartbreak after her six-year-old daughter was told she will likely not live to see her twenties. Megan Magee, 32, has spoken out about her daughter, Alana Grace Daykin, who battles a rare genetic disease that saw her spend the first two years of her life in hospital. Alana Grace Daykin, who was born at Queens Medical Centre in March 2017, suffers from Börjeson-Forssman-Lehman Syndrome (BFLS). BFLS is an extremely rare genetic condition that causes intellectual disability, obesity, and growth defects. Alana spent the first two years of her life in and out of hospital suffering from numerous health complications such as seizures and losing her eyesight. Mum-of-three, Megan, who is from Stanley in Derbyshire, hopes to fulfill her daughter's dream to get her to Florida and swim with dolphins.
