Jul 22, 2021 · Bremer Bay in Western Australia is home to a large population of Killer Whales. Learn about the Orca Life Cycle: from neonate to matriarch.

Mar 11, 2025 · The gestation period for an orca, also known as a killer whale, is approximately 17 months. This remarkably long pregnancy is the longest among all cetaceans (the group of marine mammals that includes whales, dolphins, and porpoises).

Mar 18, 2019 · Here we describe optical reconstruction of chromatin architecture (ORCA), a method that can trace the DNA path in single cells with nanoscale accuracy and genomic resolution reaching two...

Aug 28, 2020 · Researchers like Nollens say healthy orcas are more likely to become pregnant, but a few elements need to be present: a male orca of reproductive age; a cycling female orca that’s receptive to him and doesn’t have reproductive diseases; and quiet space and time to …

Mar 11, 2015 · Toothed whales such as sperm whales, orcas and dolphins hunt and catch prey in their toothy jaws, but baleen whales such as humpbacks, blues and bowhead whales gulp water and filter it through...

Here we describe optical reconstruction of chromatin architecture (ORCA), a method that can trace the DNA path in single cells with nanoscale accuracy and genomic resolution reaching two kilobases. We used ORCA to study a Hox gene cluster in cryosectioned Drosophila embryos and labelled around 30 RNA species in parallel.

Apr 18, 2023 · Here, we draw upon published and original evidence to test two hypotheses: (1) Ichthyosaurs inherited viviparity from a terrestrial ancestor. (2) Asphyxiation risk is the main reason aquatic amniotes give birth tail-first.

Aug 1, 2004 · Research was conducted to define the basic reproductive physiology of killer whales (Orcinus orca) and to use this knowledge to facilitate the development of artificial insemination procedures.

Here, we describe optical reconstruction of chromatin architecture (ORCA), an approach that simultaneously achieves these goals, and apply it to test several predictions about chromatin structure and cis-regulation in the Bithorax Complex (BX-C) of Drosophila embryos.

Feb 6, 2025 · Orcas, like humans, get baby bumps in the early months of pregnancy that grow larger as the pregnancy advances. Researchers say they can now spot those underwater baby bumps from the air and keep...
