Researchers at Brown University have solved the structure of a DNA-protein complex that aids in site-specific recombination, a process that allows mobile DNA to cut into chromosomes. The discovery provides new insights into how this process shapes species over time and its role in spreading antibiotic resistance and certain diseases.
Researchers used atomic force microscopy to study DNA's flexibility, finding it can bend into tight structures without large forces. The findings shed light on molecular properties viewed at different magnifications and have implications for cell biology and gene regulation.
Researchers discovered that nucleosomes can move to different spots in the genome, enabling efficient gene expression and regulating gene activity. This chromosomal remodeling process allows cells to turn genes on or off as needed.
Researchers successfully fabricate intricate, three-dimensional patterns on human hair using a multiphoton-absorption photopolymerization (MAP) technique. This breakthrough opens doors to potential applications in medical research, drug delivery, and miniature biodevices.
Scientists have developed a method to simultaneously track gene transcription, RNA splicing, and protein translation in living cells. The technique reveals fundamental information about how genes are switched on and off in the context of living cells.
A groundbreaking study reveals a previously undetected divergence between Pacific and Atlantic corals, finding that about one-third of Atlantic corals constitute their own unique family. This discovery highlights the need to reconsider current conservation efforts due to the severe threats faced by this distinct group.
A DNA-based computer, award-winning for smallest biological computing device, processes input molecules using spontaneous energy releases to carry out computations without external power. The device contains 15,000 trillion computers performing 330 trillion operations per second with high accuracy.
Research reveals DNA's chaotic movements limit its electrical conductivity, making it challenging for scientists to develop new molecular microelectronics. A fixed double-helix structure would improve DNA's ability to initiate reactions through charge transfer.
Scientists at the Weizmann Institute discovered that bacterial DNA forms a crystalline organization when exposed to stress, providing effective protection against oxidative agents and starvation. This finding may lead to the development of more efficient methods to fight bacterial diseases.
Researchers have identified key features of cardiac troponin C, a protein that regulates muscle contraction. The study's findings may lead to the development of new therapies for patients with congestive heart failure, by targeting calcium binding to regulatory proteins.
Researchers at Purdue University have developed an ultrathin film made from gold atoms that conducts electricity by allowing electrons to 'hop' one at a time. This new material, called linked cluster network, could lead to the development of more powerful computers and miniaturized electrical devices.
