In order to perform a wide search over the space of the trees, it is critical to solve this projection problem fast.

Measuring and making DNA is central to modern biology and biomedicine.

Haplotype assembly and viral quasispecies reconstruction are challenging tasks concerned with analysis of genomic mixtures using sequencing data.

Environment Animals Wildlife 14,000-year-old woolly rhinoceros DNA extracted from wolf's stomach The two-horned prehistoric mammal went extinct about 8,700 years ago. Breakthroughs, discoveries, and DIY tips sent six days a week. Towards the end of the last ice age, an ancient wolf feasted on a young woolly rhinoceros (). When the wolf died, it ended up buried in Siberian permafrost for about 14,000 years until it was uncovered by paleontologists in 2015. Luckily for scientists, some woolly rhinoceros tissue remained inside of the wolf's stomach.

Science sleuths think they found Leonardo da Vinci's DNA Advances in genetics might help us see what set the Renaissance man apart. The painting hangs in the Uffizi Gallery in Florence, Italy. Breakthroughs, discoveries, and DIY tips sent every weekday. Scientists are one step closer to pinpointing fragments of Leonardo da Vinci's elusive DNA . A team of researchers from the Leonardo da Vinci DNA Project analyzed samples swabbed from a red chalk drawing possibly attributed to the famed polymath, as well as letters written by one of his known cousins.

Similar to natural language models, researchers have proposed foundation models in genomics to learn generalizable features from unlabeled genome data that can then be fine-tuned for downstream tasks such as identifying regulatory elements. Due to the quadratic scaling of attention, previous Transformer-based genomic models have used 512 to 4k tokens as context (<0.001% of the human genome), significantly limiting the modeling of long-range interactions in DNA. In addition, these methods rely on tokenizers or fixed k-mers to aggregate meaningful DNA units, losing single nucleotide resolution (i.e. DNA characters) where subtle genetic variations can completely alter protein function via single nucleotide polymorphisms (SNPs). Recently, Hyena, a large language model based on implicit convolutions was shown to match attention in quality while allowing longer context lengths and lower time complexity.

Although wolf-canine interbreeding has been considered extremely rare, the latest research shows that many present-day canines carry a small amount of wolf genes. A surprising study reveals that there is a trace of wolf lurking within the tiny body of a Chihuahua and the gigantic build of a St. Bernard. An international research team from the American Museum of Natural History and the National Museum of Natural History analyzed the genomes of 2,693 dogs and wolves and found that 64.1 percent of purebred dogs carry fragments of wolf DNA. Furthermore, a study of village dogs (free-roaming dogs living in or near human communities) from around the world found genetic traces of wolves in all 280 analyzed pups. Dogs are thought to have evolved from populations of gray wolves, which became extinct during the Late Pleistocene epoch about 20,000 years ago.
