Mathematical model decodes protein interactions to show how condensates form
Biological cells are incredibly complex mixes of proteins, nucleic acids, lipids and carbohydrates. A model developed by two RIKEN researchers helps explain why components of the same type sometimes do and sometimes don't spontaneously come together.....»»
Framework helps autonomous drones rendezvous with sperm whales for better tracking
Project CETI (Cetacean Translation Initiative) aims to collect millions to billions of high-quality, highly contextualized vocalizations in order to understand how sperm whales communicate. But finding the whales and knowing where they will surface t.....»»
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.....»»
Chemoenzymatic approach enhances Stevia sweetness through glycosylation of Rebaudioside C
A research team has revealed that Rebaudioside C (Reb C), a key compound in Stevia extracts, can undergo chemoenzymatic modifications to enhance its sweetness. Researchers used engineered glycosynthases to add glucose and galactose moieties to Reb C,.....»»
Light broadens the scope of alkene synthesis
Chemists from the National University of Singapore (NUS) have developed a straightforward method to convert common chemicals like carboxylic acids, alcohols, and alkanes directly into valuable alkenes......»»
Sperm whale departure linked to decline in jumbo squid population in Gulf of California
A PeerJ study has revealed a significant departure of sperm whales (Physeter macrocephalus) from the central portion of the Gulf of California, is linked to the collapse of the jumbo squid (Dosidicus gigas) population, their primary prey......»»
First-ever artificial cell nuclei created in living egg from purified DNA injection
A research group is the first in the world to succeed in constructing artificial cell nuclei by injecting purified DNA solution instead of sperm into living mouse eggs. Their findings are published in the journal Genes to Cells......»»
Synthetic modules boost production of animal-based nutrients in plants
It's important to eat your veggies, but some essential vitamins and nutrients can only be found in animals, including certain amino acids and peptides. Now, in a proof-of-concept study published in the Journal of Agricultural and Food Chemistry, rese.....»»
Scientists find plausible geological setting that may have sparked life on Earth
Researchers have discovered a plausible evolutionary setting in which nucleic acids—the fundamental genetic building blocks of life—could enable their own replication, possibly leading to life on Earth......»»
Sound provides new information about the secret lives of sperm whales
Sperm whales are the loudest animals on Earth and rely on sound to find food in the sprawling darkness of the deep sea. MBARI technology allows us to listen in, gaining new insight into the mysterious lives of these animals......»»
Giant panda skin cells transformed into stem cells to help ensure their survival
A team of biologists in China has reprogrammed skin cells from giant pandas into induced pluripotent stem cells (iPSCs), opening the door to creating primordial germ cells that could serve as precursors to sperm and egg cells......»»
CRISPR/Cas9 modifies Euglena to create potential biofuel source
News about biofuels sometimes mentions used cooking oil as a feedstock, but if these substances contain animal fat, they can solidify in colder temperatures. This happens because, chemically, the fatty acids of these and many other saturated fats hav.....»»
Glitch in protein synthesis could affect tumor growth
During protein synthesis, or translation, genetic information transcribed in the cell's mRNA directs the stringing together of amino acids—the building blocks of proteins. As the translation machinery carouses along the string of nucleotides that m.....»»
Compounds from nucleic acids in food show anticancer effects
When people eat, they ingest the nucleic acids that reside in all living things. The compounds in these acids could inhibit the growth of cancer cells, according to findings published in PLOS ONE by Osaka Metropolitan University Associate Professor A.....»»
Tomato ripening study highlights cell wall component interactions
Tomato fruit ripening involves intricate biochemical and structural changes, particularly within the cell wall, which are vital for the fruit's final texture and quality. These changes include modifications in polysaccharides and proteins, but the sp.....»»
New genetic sensor for DNA methylation discovered
DNA methylation is a process in which a methyl group is attached to the cytosine base of the DNA molecule, and is a major way that DNA is epigenetically marked. Epigenetic modifications can act as on–off switches to regulate gene expression and hel.....»»
