Mixed mRNA tails act like a shield that delays its shortening
Thu, 19 Jul 2018 14:21:51 EDT
Biologists have identified how mixed tails -- made of different nucleotides -- protect mRNA from degradation for longer. This study could bring new insights to our understanding of gene regulation in healthy and diseased states.
Scientists develop proteins that self-assemble into supramolecular complexes
Thu, 19 Jul 2018 09:44:08 EDT
Scientists have designed new proteins that can self-assemble into the complex structures underlying biological organisms, laying the groundwork for leading-edge applications in biotechnology. The researchers created and developed the proteins with a specific function and their method reveals a possibility that certain protein functions can be created on demand. It is expected to contribute to the development of nanobiomaterials, which could be used as a drug delivery system or an artificial vaccine.
In the ocean's twilight zone, tiny organisms may have giant effect on Earth's carbon cycle
Wed, 18 Jul 2018 17:03:08 EDT
In a new study that challenges scientists' presuppositions about the carbon cycle, researchers find that tiny organisms may be playing in outside role in the way carbon is circulated throughout the ocean.
Scientists uncover DNA 'shield' w/crucial roles in normal cell division
Wed, 18 Jul 2018 14:30:55 EDT
New fundamental complex in cells drives 'messy' form of DNA repair. In immune cells, this is crucial to make antibodies. In cancer, mutations in complex could lead to resistance to BRCA-targeting PARP inhibitor drugs or platinum chemotherapies.
Glowing bacteria on deep-sea fish shed light on evolution, 'third type' of symbiosis
Wed, 18 Jul 2018 14:30:50 EDT
For the first time, scientists have sequenced and analyzed the genomes of bacteria that live in anglerfish bulbs. The bacteria were taken from fish specimens collected in the Gulf of Mexico.
