While best known as the code for genetic information, DNA is also a nutrient for specialised microbes. An international team of researchers led by Kenneth Wasmund and Alexander Loy from the University of Vienna has discovered several bacteria in sediment samples from the Atlantic Ocean that use DNA as a food source.
Summer picnics and barbecues are only a few weeks away! As excited as you are to indulge this summer, Escherichia coli bacteria are eager to feast on the all-you-can-eat buffet they are about to experience in your gut. However, something unexpected will occur as E. coli cells end their journey through your digestive tract. Without warning, they will find themselves swimming in your toilet bowl, clinging to the last bits of nutrients attached to their bodies.
The San Francisco Declaration on Research Assessment (DORA) is proud to announce “SPACE to Evolve Academic Assessment: A rubric for analyzing institutional conditions and progress indicators.” The SPACE rubric is the latest resource from DORA designed to support the development of fair and responsible academic assessment practices.
Scientists are hoping the RNA of an obscure infection can one day be used like a Trojan horse to deliver life-saving treatments to citrus trees.
Researchers show that polymerase theta can efficiently convert RNA sequences back into DNA, a feat more common in viruses than eukaryotic cells.
It eventually became a Nobel prize-winning revolution when researchers first engineered CRISPR as a gene editing technology for bacterial, plant, animal and human cells.
Changing your eating habits or altering your circadian clock can impact healthy fat tissue throughout your lifespan, according to a preclinical study published today in Nature by researchers with The University of Texas Health Science Center at Houston (UTHealth).
DALLAS – June 9, 2021 – A phenomenon in which an RNA named NORAD drives a protein named Pumilio to form liquid droplets in cells, much like oil in water, appears to tightly regulate the activity of Pumilio. A new study led by UT Southwestern scientists suggests that such RNA-driven “phase separation,” in turn, protects against genome instability, premature aging, and neurodegenerative diseases, and may represent a previously unrecognized way for RNAs to regulate cellular processes.
Researchers have shown that even after lung tissue has been damaged, it may be possible to reverse fibrosis and promote tissue repair through treatment with microgel-coated mesenchymal stromal cells.
It can be easy to forget that the human skin is an organ. It’s also the largest one and it’s exposed, charged with keeping our inner biology safe from the perils of the outside world. But Michigan State University’s Sangbum Park is someone who never takes skin or its biological functions for granted. He’s studying skin at the cellular level to better understand it and help us support it when it’s fighting injury, infection or disease.
Jack E. Dixon, whose distinguished and varied 48-year career ranged from helping reveal how cells communicate to becoming a renowned scientific leader at UC San Diego School of Medicine and Howard Hughes Medical Institute, is retiring.
Each city has its own unique microbiome, a "fingerprint" of viruses and bacteria that uniquely identify it, according to a new study from an international consortium of researchers that included a team from the University of Maryland School of Medicine (UMSOM). The international project, which sequenced and analyzed samples collected from public transit systems and hospitals in 60 cities around the world, was published today in the journal Cell.
All living organisms are equipped with sensory organs to detect changes in their surrounding environment.
Scientists from Hokkaido University have discovered a novel defensive response to SARS-CoV-2 that involves the viral pattern recognition receptor RIG-I.
DALLAS – May 21, 2021 – One member of a large protein family that is known to stop the spread of bacterial infections by prompting infected human cells to self-destruct appears to kill the infectious bacteria instead, a new study led by UT Southwestern scientists shows. However, some bacteria have their own mechanism to thwart this attack, nullifying the deadly protein by tagging it for destruction.
For the first time, researchers have successfully sequenced the entire genome from the skull of Peştera Muierii 1, a woman who lived in today's Romania 35,000 years ago.
By mapping its genetic underpinnings, researchers at University of California San Diego School of Medicine have identified a predictive causal role for specific cell types in type 1 diabetes, a condition that affects more than 1.6 million Americans.
