Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

Alexandrian Laurel (Calophyllum inophyllum)

Alexandrian Laurel ( Calophyllum inophyllum ) is a species of plant in the Calophyllaceae family. It is a low-branching, slow-growing, spreading tree with a wide, irregular crown.

Thomas Sutikna lives with Homo floresiensis

BLOG - On October 28, 2004, a paper was published in Nature describing the dwarf hominin we know today as Homo floresiensis that has shocked the world. The report changed the geographical landscape of early humans that previously stated that the Pleistocene Asia was only represented by two species, Homo erectus and Homo sapiens . The report titled "A new small-bodied hominin from the Late Pleistocene of Flores, Indonesia" written by Peter Brown and Mike J. Morwood from the University of New England with Thomas Sutikna, Raden Pandji Soejono, Jatmiko, E. Wahyu Saptomo and Rokus Awe Due from the National Archaeology Research Institute (ARKENAS), Indonesia, presents more diversity in the genus Homo. “Immediately, my fever vanished. I couldn’t sleep well that night. I couldn’t wait for sunrise. In the early morning we went to the site, and when we arrived in the cave, I didn’t say a thing because both my mind and heart couldn’t handle this incredible moment. I just went down...
