Researcher uses pressure to understand RNA dynamics      (via sciencedaily.com)     Original source 

Just as space holds infinite mysteries, when we zoom in at the level of biomolecules (one trillion times smaller than a meter), there is still so much to learn. Scientists are studying the conformational landscapes of biomolecules and how they modulate cell function. When biomolecules receive certain inputs, it can cause the atoms to rearrange and the biomolecule to change shape. This change in shape affects their function in cells, so understanding conformational dynamics is critical for drug development.

'We're all Asgardians': New clues about the origin of complex life      (via sciencedaily.com)     Original source 

According to a new study, eukaryotes -- complex life forms with nuclei in their cells, including all the world's plants, animals, insects and fungi -- trace their roots to a common Asgard archaean ancestor. That means eukaryotes are, in the parlance of evolutionary biologists, a 'well-nested clade' within Asgard archaea, similar to how birds are one of several groups within a larger group called dinosaurs, sharing a common ancestor.

The molecular control center of our protein factories      (via sciencedaily.com)     Original source 

Researchers have deciphered a biochemical mechanism that ensures that newly formed proteins are processed correctly when they leave the cell's own protein factories. This solves a decade-old puzzle in protein sorting.

Unraveling the connections between the brain and gut      (via sciencedaily.com)     Original source 

Engineers designed a technology to probe connections between the brain and the digestive tract. Using fibers embedded with a variety of sensors, as well as optogenetic stimulation, the researchers could control neural circuits connecting the gut and the brain, in mice.

A roadmap for gene regulation in plants      (via sciencedaily.com)     Original source 

For the first time, researchers have developed a genome-scale way to map the regulatory role of transcription factors, proteins that play a key role in gene expression and determining a plant's physiological traits. Their work reveals unprecedented insights into gene regulatory networks and identifies a new library of DNA parts that can be used to optimize plants for bioenergy and agriculture.

Cave excavation pushes back the clock on early human migration to Laos      (via sciencedaily.com)     Original source 

Fifteen years of archaeological work in the Tam Pa Ling cave in northeastern Laos has yielded a reliable chronology of early human occupation of the site. The team's excavations through the layers of sediments and bones that gradually washed into the cave and were left untouched for tens of thousands of years reveals that humans lived in the area for at least 70,000 years -- and likely even longer.

Now, every biologist can use machine learning      (via sciencedaily.com)     Original source 

Scientists have built a new, comprehensive AutoML platform designed for biologists with little to no ML experience. New automated machine learning platform enables easy, all-in-one analysis, design, and interpretation of biological sequences with minimal coding. Their platform, called BioAutoMATED, can use sequences of nucleic acids, peptides, or glycans as input data, and its performance is comparable to other AutoML platforms while requiring minimal user input.

Cryo conservation: A cool solution to saving species from extinction      (via sciencedaily.com)     Original source 

In the face of the biodiversity crisis, and alarming data showing a 69% decline in global animal populations since 1970, researchers are banking on a cool solution to help save species from extinction. Much like egg-freezing is used to preserve human fertility options for a later date, the cryo-freezing of genetic samples taken from animals may play an essential role in curbing species extinctions. A new study sheds light on the immense potential of living cell banks, also known as cryobanks, to contribute to global conservation priorities.

These long-necked reptiles were decapitated by their predators, fossil evidence confirms      (via sciencedaily.com)     Original source 

In the age of dinosaurs, many marine reptiles had extremely long necks compared to reptiles today. While it was clearly a successful evolutionary strategy, paleontologists have long suspected that their long-necked bodies made them vulnerable to predators. Now, after almost 200 years of continued research, direct fossil evidence confirms this scenario for the first time in the most graphic way imaginable.

A new tool to study complex genome interactions      (via sciencedaily.com)     Original source 

Genome Architecture Mapping captures complex, multi-way interactions in the genome. This is different than the workhorse technique of 3D genomics, which sees mostly two-way contacts, finds a new study.

Close up on aging reveals how different cell types in the body age at different pace      (via sciencedaily.com)     Original source 

A team or researchers reports the first Aging Fly Cell Atlas (AFCA), a detailed characterization of the aging process in 163 distinct cell types in the laboratory fruit fly. Their in-depth analysis revealed that different cell types in the body age differently, each cell type following a process involving cell type-specific patterns. AFCA provides a valuable resource for researchers in the fruit fly and aging communities as a reference to study aging and age-related diseases and to evaluate the success of anti-aging strategies.
