Some frogs actually give birth to toadlets; a fungus and bacterium have an unusual symbiosis; hyena behavior is gentler than we knew | Microbiology
6+ hour, 15+ min ago (375+ words) A Fungus & Bacterium Have a Symbiosis that Changes the Severity of Fungal Disease This study was based on samples of P. griseola that were obtained from Puerto Rico, Honduras, Guatemala, and Tanzania. The investigators isolated and sequenced DNA from these samples…...
Revealing the Hidden Microproteins of the Dark Proteome | Cell And Molecular Biology
2+ mon, 1+ day ago (226+ words) Proteins typically have a three-dimensional structure and are made up of strings of amino acids. But an amino acid string needs to only be a certain length, and have a likely biological role to be considered a protein. But it…...
Cyanobacteria Find Another Use for DNA | Microbiology
2+ mon, 1+ week ago (367+ words) One particular multicellular cyanobacterium that has been studied for decades is known as Anabaena sp. PCC 7120. Researchers have shown that there has been a significant evolutionary change in this microbe that has taken an ancient process for segregating DNA during…...
Finding the Molecular Link Between Fasting & Longer Lifespans | Cell And Molecular Biology
2+ mon, 3+ week ago (219+ words) Previous work by Douglas and colleagues indicated that NHR-49 monitors intracellular lipid stores too, and triggers a process to prevent cells from starving if lipid supplies run low. The researchers eliminated NHR-49 expression in C. elegans, and withheld food from the…...
Uncloaking a Sleeping Sickness Mystery | Microbiology
3+ mon, 1+ week ago (232+ words) The protein characterized in this study works as a ‘molecular shredder’ that eliminates RNA transcripts; these are created by the cell when an active gene should be made into protein. But the molecular shredder known as ESB2 can destroy RNA, even…...
Revealing the Mechanisms Behind Cold Sensations | Cell And Molecular Biology
3+ mon, 2+ week ago (233+ words) "Everyone always wants to know how temperature sensing works, but it turns out to be a very technically challenging question to answer," said Julius, co-corresponding study author and Chair of Molecular Biology and Medicine, and of Physiology at the University…...
Confident protein validation: The power of SDS-PAGE and Western blot in ÄKTA™ chromatography workflow | Cell And Molecular Biology
3+ mon, 2+ week ago (376+ words) Why validate after protein purification When combined with the Amersham™ ImageQuant™ 800 Western blot imaging system and ImageQuant™ TL analysis software, researchers can quickly perform quantitative densitometry to determine whether the purification was satisfactory or whether further optimization is needed. This…...
A Cells' Active Genes Can Now be Seen in Unprecedented Detail | Genetics And Genomics
3+ mon, 3+ week ago (215+ words) This latest technique is called Seq-Scope-eXpanded, or Seq-Scope-X. It enables scientists to visualize the barriers between cells and the genetic transcripts they contain, even when they are in different parts of the cell, such as the cytoplasm or nucleus. “We…...
Antibacterial Help From Another Domain of Life | Microbiology
10+ mon, 3+ week ago (282+ words) To address this problem, some researchers have begun to study other microorganisms. Since bacteria have to compete with other bacteria for space and resources, they often produce antimicrobial drugs. Investigators wanted to know if archaea, single-celled organisms that are similar…...
