Different sperm whale ‘dialects’ detected on separate sides of the Mediterranean
Matriarchal groups in east and west exhibit distinct click patterns, used to form social structuresFrom “Howdy” to “G’day”, English – like other languages – is rich in dialects. Now researchers have found sperm whales on different sides of the Mediterranean show similar variation
Synthetic DNA toolkit expands scientists' ability to recognize genetic targets
A new method for recognizing and targeting DNA that dramatically expands the range of genetic sequences scientists can identify has been developed by experts at the University of Portsmouth. Published this week in Nature Communications, the research opens new possibilities for ge
DNA databases unite to create a fully open resource for transposable element research
For more than three decades, researchers studying genomes have relied on foundational resources such as Repbase and, more recently, Dfam to identify and classify transposable elements—the mobile DNA sequences that shape genome structure, evolution and function. Now, Dfam and Repb
Purine-heavy DNA sequences protect Bacillus subtilis genes from Rho termination
In the study of bacteria, a longstanding dogma has held that two molecular machines—RNA polymerase, which leads the way in transcribing DNA into RNA, and ribosomes, which bring up the rear translating RNA into proteins—worked so closely in tandem that they were effectively attach
AI system translates protein sequences into text, helping reveal functions of unknown prot
In a paper published in Proceedings of the National Academy of Sciences, researchers from Technion and Tel Aviv University present BetaDescribe, an AI system that translates protein sequences into natural-language descriptions, opening a new path toward understanding protein func
How cells keep genomic hitchhikers under control
Much of the genome is made up of repetitive DNA sequences that trace back to ancient mobile elements, many of which have lost their ability to copy themselves into new locations but can still cause problems if they become active again at the wrong time. Now, two studies published
Harvard scientists turn a silicon chip into a DNA writing machine
Scientists have created a silicon chip that can write dozens of DNA sequences simultaneously using electricity and water-based enzymes, offering a cleaner alternative to conventional DNA manufacturing. The breakthrough could eventually support portable DNA-writing devices and eve
AI helps scientists improve prediction of which DNA sequences bind to each other
Researchers have demonstrated a novel AI model that can predict which DNA molecules bind with other DNA molecules. A more thorough understanding of these hypercomplex binding relationships has utility in applications ranging from biomedical diagnostic tools to DNA computing.

A Odisseia é chamado de "um dos melhores filmes" de Christopher Nolan
O mês de julho marcará o retorno de Christopher Nolan (Oppenheimer) às telonas com sua adaptação de A Odisseia, e as primeiras reações dos críticos apontam para uma das melhores produções da carreira do cineasta. Inspirado no poema épico de Homero, A Odisseia narra a grandiosa jornada de Odisseu (Matt Damon), o rei de Ítaca, que enfrenta diversos desafios para voltar para casa após a Guerra de Troia. De acordo com os especialistas da área, que tiveram a oportunidade de assistir ao l
