10+ hour, 2+ min 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…...

1+ week, 2+ day 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…...

3+ week, 1+ day 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…...

1+ mon, 6+ day 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…...

1+ 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…...

1+ mon, 2+ week ago  (376+ words) Why validate after protein purification When combined with the Amersham" Image Quant" 800 Western blot imaging system and Image Quant" TL analysis software, researchers can quickly perform quantitative densitometry to determine whether the purification was satisfactory or whether further optimization is…...

1+ mon, 2+ week ago  (215+ words) This latest technique is called Seq-Scope-e Xpanded, 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....

8+ 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…...
