Study reveals dynamics of DNA ligation during genome replication
Unconnected strands of DNA must be sealed together during genome replication and repair, and a new KAUST-led investigation shows how the fastening enzyme involved gets the job done......»»
New enzyme could mean better drugs
Just as a choreographer's notation tells a dancer to strike a particular pose, an enzyme newly discovered by Rice University scientists is able to tell specific molecules precisely how to arrange themselves, down to the angle of single hydrogen bonds.....»»
Beautiful LED Pendant In Three Steps
Wearable glowing accessories — we often associate them with Halloween costumes or a packed concert. While those are definitely fun, I wanted to make elegant jewelry, fit to wear on a night out with friends or a casual day at work. There’s som.....»»
Scientists solve the mystery of why OGT enzyme is critical for cell survival
Researchers at La Jolla Institute for Immunology (LJI) have at last uncovered how an enzyme called O-GlcNAc transferase (OGT) keeps cells healthy. Their findings, published in the Proceedings of the National Academies of Sciences, reveal a key aspect.....»»
Astronomers spot unusual stellar explosion rich in oxygen and magnesium
A study led from the University of Turku, Finland, discovered a supernova explosion that expands the understanding of the later life stages of massive stars......»»
DNA repair scheme gets closer look for cancer therapy
Researchers from Rice University and St. Jude Children's Research Hospital in Memphis, Tennessee, Have taken a close look at one of the ways cells repair broken strands of DNA and discovered details that could help make a particular enzyme a promisin.....»»
James Webb image shows the bright glowing heart of a galaxy
Astronomers recently shared a stunning new image of space from the James Webb Space Telescope, showing a galaxy with an unusually bright heart......»»
2-billion-year-old enzyme reconstructed: Detective work by molecular biologists and bioinformatics researchers
Researchers at Leipzig University have solved a puzzle in the evolution of bacterial enzymes. By reconstructing a candidate for a special RNA polymerase as it existed about 2 billion years ago, they were able to explain a hitherto puzzling property o.....»»
Study finds well-known enzyme also performs quality control of membrane proteins
An interdisciplinary team of scientists from Cologne, Heidelberg and Munich have discovered a new function of a well-known enzyme. The signal peptidase complex in the endoplasmic reticulum cleaves faulty membrane proteins to initiate their degradatio.....»»
Lava from Hawaii volcano slows its approach to key highway
Rivers of glowing lava oozing from the world's largest volcano shouldn't be able to reach the main highway linking the east and west coasts of Hawaii's Big Island for at least a week, an official said Thursday......»»
Viewers flock to watch glowing lava ooze from Hawaii volcano
The world's largest volcano oozed rivers of glowing lava Wednesday, drawing thousands of awestruck viewers who jammed a Hawaii highway that could soon be covered by the flow......»»
Lava from Hawaii volcano lights night sky amid warnings
Waves of orange, glowing lava and ash blasted and billowed from the world's largest active volcano in its first eruption in 38 years, and officials told people living on Hawaii's Big Island to be ready in the event of a worst-case scenario......»»
RNA enzyme ensures development of red blood cells by safeguarding genome integrity
The body needs a lot of blood. In humans, 200 billion new erythrocytes—or red blood cells—are generated daily by erythropoiesis, a multi-step process starting from blood-related stem cells, requiring rigorous maintenance of DNA integrity. Until n.....»»
Erupting Hawaii volcano spurs warning for people to prepare
Waves of orange, glowing lava and smoky ash belched and sputtered Monday from the world's largest active volcano in its first eruption in 38 years, and officials told people living on Hawaii's Big Island to be ready in the event of a worst-case scena.....»»
Hawaii"s Mauna Loa erupts, officials warn people to prepare
Waves of orange, glowing lava and smoky ash erupted Monday from the world's largest active volcano and people living on Hawaii's Big Island were warned to be ready should debris threaten communities......»»
Cell division enzyme earmarked as potential new cancer therapeutic target
To make new cells, we have to divide existing ones. This is a continuous, frequent and ubiquitous process which starts at conception and ends at death. There are an estimated 37 trillion cells in the tissues and organs of the human body, each of whic.....»»
Scientists develop novel mode of linear hybridization chain reaction
Hybridization chain reaction refers to an enzyme-free nucleic acid polymerization reaction. A target molecule triggers cascade hybridization reactions by several thermodynamically stable DNA fuel strands, producing ultra-long DNA nanostructures with.....»»
Study investigates a rare Type Icn supernova
An international team of astronomers has conducted optical and near-infrared observations of a rare Type Icn supernova known as SN 2022ann. The results of the study, published November 9 on the preprint server arXiv, shed more light on the nature of.....»»
