Published Plastic pollution can kill variety of ocean embryos
(via sciencedaily.com) Original source High levels of plastic pollution can kill the embryos of a wide range of ocean animals, new research shows.
Published How tardigrades can survive intense radiation
(via sciencedaily.com) Original source Researchers have discovered that tardigrades -- microscopic animals famed for surviving harsh extremes -- have an unusual response to radiation.
Published Unlocking the 'chain of worms'
(via sciencedaily.com) Original source An international team of scientists has published a single-cell atlas for Pristina leidyi (Pristina), the water nymph worm, a segmented annelid with extraordinary regenerative abilities that has fascinated biologists for more than a century.
Published Clear guidelines needed for synthetic data to ensure transparency, accountability and fairness, study says
(via sciencedaily.com) Original source Clear guidelines should be established for the generation and processing of synthetic data to ensure transparency, accountability and fairness, a new study says.
Published Cell's 'garbage disposal' may have another role: Helping neurons near skin sense the environment
(via sciencedaily.com) Original source The typical job of the proteasome, the garbage disposal of the cell, is to grind down proteins into smaller bits and recycle some of those bits and parts. That's still the case, for the most part, but researchers, studying nerve cells grown in the lab and mice, say that the proteasome's role may go well beyond that.
Published How seaweed became multicellular
(via sciencedaily.com) Original source A deep dive into macroalgae genetics has uncovered the genetic underpinnings that enabled macroalgae, or 'seaweed,' to evolve multicellularity. Three lineages of macroalgae developed multicellularity independently and during very different time periods by acquiring genes that enable cell adhesion, extracellular matrix formation, and cell differentiation, researchers report. Surprisingly, many of these multicellular-enabling genes had viral origins. The study, which increased the total number of sequenced macroalgal genomes from 14 to 124, is the first to investigate macroalgal evolution through the lens of genomics.
Published First step to untangle DNA: Supercoiled DNA captures gyrase like a lasso ropes cattle
(via sciencedaily.com) Original source Researchers reveal how DNA gyrase resolves DNA entanglements. The findings not only provide novel insights into this fundamental biological mechanism but also have potential practical applications. Gyrases are biomedical targets for the treatment of bacterial infections and the similar human versions of the enzymes are targets for many anti-cancer drugs. Better understanding of how gyrases work at the molecular level can potentially improve clinical treatments.
Published Breakthrough promises secure quantum computing at home
(via sciencedaily.com) Original source The full power of next-generation quantum computing could soon be harnessed by millions of individuals and companies, thanks to a breakthrough guaranteeing security and privacy. This advance promises to unlock the transformative potential of cloud-based quantum computing.
Published Biofortified rice to combat deficiencies
(via sciencedaily.com) Original source Vitamin B1 is an essential micronutrient for human beings. Its deficiency is the cause of numerous diseases of the nervous and cardiovascular systems. Researchers have achieved a significant advance in the fight against vitamin B1 deficiency, frequently associated with a rice-based diet. By specifically targeting the nourishing tissues of the rice grain, the scientists have succeeded in considerably increasing its vitamin B1 content, without compromising agronomic yield. These results could help solve a major public health problem in regions where rice is the staple food.
Published Cockayne syndrome: New insights into cellular DNA repair mechanism
(via sciencedaily.com) Original source Researchers decode repair mechanism during transcription of genetic information.
Published Machine learning method reveals chromosome locations in individual cell nucleus
(via sciencedaily.com) Original source Researchers have made a significant advancement toward understanding how the human genome is organized inside a single cell. This knowledge is crucial for analyzing how DNA structure influences gene expression and disease processes.
Published Different means to the same end: How a worm protects its chromosomes
(via sciencedaily.com) Original source Researchers have discovered that a worm commonly used in the study of biology uses a set of proteins unlike those seen in other studied organisms to protect the ends of its DNA.
Published Scientists grow 'mini kidneys,' revealing new insights into metabolic defects and potential therapy for polycystic kidney disease
(via sciencedaily.com) Original source Scientists have successfully grown 'mini kidneys' in the lab and grafted them into live mice, revealing new insights into the metabolic defects and a potential therapy for polycystic kidney disease.
Published Toothed whale echolocation organs evolved from jaw muscles
(via sciencedaily.com) Original source Genetic analysis finds evidence suggesting that acoustic fat bodies in the heads of toothed whales were once the muscles and bone marrow of the jaw.
Published Protecting art and passwords with biochemistry
(via sciencedaily.com) Original source A new molecular test method helps to prove the authenticity of works of art. The new method could also help to make passwords secure against quantum computers.
Published Can language models read the genome? This one decoded mRNA to make better vaccines
(via sciencedaily.com) Original source Researchers developed a foundational language model to decode mRNA sequences and optimize those sequences for vaccine development. The tool shows broader promise as a means for studying molecular biology.
Published New tools reveal how genes work and cells organize
(via sciencedaily.com) Original source Researchers have discovered how certain proteins can attach to special structures in RNA, called G-quadruplexes. Additionally, they have developed computational tools capable of predicting these protein-RNA interactions. The newfound ability to predict these interactions can help future work in understanding molecular pathways in the cell and pave the way for developing drugs targeting these RNA G-quadruplex binding proteins, that are found to be involved in disease such as cancer.
Published 100 kilometers of quantum-encrypted transfer
