Researchers at St. Jude Children's Research Hospital discovered that smaller sub-compartments within the nucleolus form to finish the final steps of ribosome assembly. These sub-compartments lock major ribosome building blocks together until they are assembled, preventing a key protein from associating with them prematurely.
Scientists have captured 3D snapshots of individual RNA nanoparticles in motion, showcasing the dynamic and intricate folding process. This breakthrough uses advanced electron microscopy to study RNA's flexibility, enabling new insights into its structure and potential applications in molecular medicine.
Researchers at Kumamoto University identified G-quadruplexes as a central role in promoting alpha-synuclein aggregation, leading to neurodegenerative diseases. Inhibiting G4 assembly may prevent the onset of synucleopathies and position it as a promising target for early intervention.
Researchers demonstrate the first cross-chiral exponential amplification of an RNA enzyme, potentially leading to the development of cross-chiral therapeutics and biotechnologies. The discovery suggests that a bioengineer can create a new form of biochemical evolution by using both left- and right-handed molecules.
A team of UConn researchers, without lab experience, published the first chromosome-level genome of a desert hairy scorpion. The study sheds light on arachnid evolution and advances comparative genomics research.
Researchers have determined the molecular level function of free-forming structures in plant cells that help sense light and temperature, enabling plants to distinguish a range of different light intensities. The formation of these organelles is not random but is linked to specific locations within the cell, particularly near centromeres.
Lepodisiran, a short interfering RNA, targets hepatic synthesis of apolipoprotein(a), reducing serum lipoprotein(a) concentrations. Phase 1 study results support further investigation of lepodisiran's efficacy in treating elevated lipoprotein(a) levels.
Scientists have made a significant breakthrough in understanding the assembly of ribosomes, the essential nanomachines that translate genetic information into proteins. A new study has provided high-resolution images of the large ribosomal subunit, revealing key steps in its formation and maturation. The findings bring researchers clos...
Researchers have shed new light on viral genome replication machinery, revealing its intricate structure at atomic resolution. The study, published in PNAS, provides essential insights into the assembly, dynamic operation, and potential therapeutic targets of this complex machine.
A new theory suggests that small organic molecules may assemble into self-replicating biomolecules on the surfaces of silica-rich minerals, providing a potential mechanism for life's origin. Geophysicist Joseph V. Smith proposes that organophilic zeolites could have concentrated and protected these organic compounds from destruction.
