"ZIP" codes tell RNA molecules how to get to their designated locations
They say that life comes without an instruction manual, but that's not entirely true. Each cell in our bodies lives according to instructions issued by its DNA in the form of RNA molecules. RNA was recently thrust into the limelight as the basis of i.....»»
Astronomers use JWST and ALMA to explore the structure of a giant spiral galaxy
Using the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers have observed a giant spiral galaxy designated ADF22.A1. Results of the observational campaign, published Oc.....»»
Gamma radiation converts methane into complex organic molecules and could explain the origin of life
Gamma radiation can convert methane into a wide variety of products at room temperature, including hydrocarbons, oxygen-containing molecules, and amino acids, according to a new article published in the journal Angewandte Chemie International Edition.....»»
Apple Stores in three U.S. cities will change locations on November 9
Apple Stores in three U.S. cities will move to new temporary locations on November 9, possibly due to renovations. Here's what you need to know.Apple's La Encantada store is moving to a new location. Image Credit: Apple.On Tuesday, Apple announced th.....»»
Testing thousands of RNA enzymes helps find first "twister ribozyme" in mammals
The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA—a single-stranded molecule similar in many ways to DNA—like some modern viruses. This is because, like DNA, RNA can carry genetic information, but, lik.....»»
Mangrove degradation threatens carbon storage in China"s Pearl Bay
Carbon sinks are important in the fight against climate change as they draw down atmospheric carbon dioxide levels by storing organic carbon in the oceans and soil, for example. Within tropical and subtropical intertidal locations, wetland plant comm.....»»
RNA sequencing approach offers real-time and programmable transcriptome sequencing
The high complexity and diversity of the eukaryotic transcriptome poses significant challenges for the efficient detection of specific transcripts. Conventional targeted RNA-seq methods often require labor-intensive pre-sequencing enrichment steps, w.....»»
Chiral molecular self-assemblies that absorb light boost singlet fission process, research demonstrates
In organic molecules, an exciton is a particle bound pair of an electron (negative charge) and its hole (positive charge). They are held together by Coulombic attraction and can move within molecular assemblies. Singlet fission (SF) is a process wher.....»»
International team discovers small molecules that regulate how fast plant leaves age
Two small molecules that are produced by the plant Arabidopsis thaliana are shown to have the opposite effect on how fast its leaves age. The molecules are peptides, short chains of amino acids. While the peptide SCOOP10 accelerates aging, SCOOP12 su.....»»
Single-molecule tracking technology streamlines drug discovery
New drug discovery is a critical step for improving patients' lives. First, researchers must identify molecules in the body's cells that help drive disease, as these are potential targets for new drugs. The next step is to screen candidate drugs that.....»»
Novel polypeptide-based molecules could pave the way for enhanced polymer design
A research study describes a systematic high-throughput design approach for virtual screening and creation of novel polypeptide-based molecules that form regular secondary structures that can be used in biology or materials science research. The stud.....»»
Researchers observe stick-slip phenomenon in carbon nanotube fibers
The shapes of simple polyatomic molecules such as carbon dioxide and methane are characterized by a specific symmetry depending on the manner of linking of the atoms. Nano- to micrometer-sized particles that mimic the shapes of such polyatomic molecu.....»»
See the polar moon sites where NASA plans to land its astronauts
NASA has plans to send astronauts back to the moon in 2026. Now, it is sharing a short list of locations where they could land......»»
Scientists provide direct evidence of breakdown of spin statistics in ion-atom charge exchange collisions
Since the first X-ray image of a comet was reported using an X-ray telescope in 1996, the investigation of charge exchange in collisions between highly charged ions and atoms or molecules has emerged as a hot research topic......»»
Scientists create a molecular switch that can control cell division on demand outside of a living system
A living cell is a bustling metropolis, with countless molecules and proteins navigating crowded spaces in every direction. Cell division is a grand event which completely transforms the landscape. The cell starts behaving like the host of an interna.....»»
Tracking a disappearing mantle plume in ancient Samoa: Researchers shed light on a 30-million-year gap
When plumes of magma well up through Earth's lithosphere, they create volcanoes, islands, seamounts, and other features on the surface. Telltale hot spot tracks form as tectonic plates move over these plumes, marking plume locations and the movement.....»»
CRISPR-Cas10 can flood virally infected bacteria with toxic molecules, researchers discover
CRISPR-Cas9 has long been likened to a kind of genetic scissors, thanks to its ability to snip out any desired section of DNA with elegant precision......»»
Unique multidomain enzymes from bacteria identified
Pharmaceutical scientists from the National University of Singapore (NUS) have identified and characterized a unique multidomain enzyme capable of catalyzing two distinct types of reactions, both vital for making drug molecules......»»
Mary, Queen of Scots and the clandestine tricks of the women who kept her secrets
Mary, Queen of Scots spent almost 20 years in captivity. She was held in various locations across Britain from 1568 until her execution on February 8, 1587. As I explain in my new book, Captive Queen: The Decrypted History of Mary, Queen of Scots, du.....»»
How to Pack-A-Punch in Black Ops 6 Zombies: Liberty Falls and Terminus locations
