Novel strategy proposed for selectively targeting G-quadruplex at specific genome loci
DNA G-quadruplexes (G4s) are a type of quadruple helix structure formed by a continuous guanine-rich DNA sequence. Although DNA G4s are thought to be involved in various biological processes, in many cases their causative effects are largely unclear.....»»
Webb captures a staggering quasar-galaxy merger in the remote universe
An international research group led by the Italian National Institute for Astrophysics (INAF) and comprising 34 research institutes and universities worldwide utilized the Near-Infrared Spectrograph (NIRSpec) on board the James Webb Space Telescope (.....»»
Elusive temporary star described in historical documents recreated using new computer model
A mysterious remnant from a rare type of supernova recorded in 1181 has been explained for the first time. Two white dwarf stars collided, creating a temporary "guest star," now labeled supernova (SN) 1181, which was recorded in historical documents.....»»
Investigations of the polysomatism of antigorite under pressure
Antigorite is a type of serpentine, which is the most abundant hydrated mineral on the Earth. It is widely believed that this mineral is the main carrier of water deep into the Earth in subducting oceanic plates. It has a wavy structure along the a-a.....»»
The influence of peptoid sequence on the mechanisms and kinetics of 2D assembly
Two-dimensional (2D) materials have unique physical and chemical properties and potential for a wide variety of applications. Peptoids, a type of molecule, compose a class of sequence-defined polymers that mimic biological compounds and can self-asse.....»»
Experimental bermudagrasses show varied drought response
In a new study, researchers at Oklahoma State University have unveiled significant variations in drought response among advanced turf-type Bermudagrass experimental genotypes. The study aimed to evaluate the drought tolerance of various Bermudagrass.....»»
Scholars review lunar crater chronology and impact flux
Scholars reviewed the existing anchor points and construction history of lunar crater chronology. Before the return of lunar samples, the stratification of the near side of the moon was based on remote sensing data from ground-based telescopes and lu.....»»
Identity verification company AU10TIX – used by tech giants – left photo IDs exposed
If there’s one type of company you definitely don’t want to see left vulnerable to hackers it’s an identity verification service with access to photo ID documents like driver’s licenses – but that’s exactly what appears to have happened w.....»»
High-precision infrared imaging technology reveals the magnetic domain structure of non-collinear antiferromagnets
Non-collinear antiferromagnetic materials, which have a net magnetic moment of nearly zero, yet exhibit significant anomalous transverse transport properties, are considered candidate materials for the next generation of spintronic devices......»»
