Rhino rattan (Plectocomia elongata)

Rhino rattan (Plectocomia elongata) is a species of plant in the Arecaceae, large rattan, single or in clusters, up to 50 meters high, large stem, segment length 30-40 cm, diameter with leaf midrib up to 25-100 mm, grows in forests, along rivers and slopes in the lowlands up to an elevation of 1200 meters.

P. elongata has leaves 6-7 meters long, including a 3 meter apex and a 20-30 cm petiole. The leaf midrib is green with many horizontal spines or rosettes. The leaves number 50-60 on the right and left of the rakis, in the shape of oblong bands, arranged irregularly or in groups of 1-4 items, the upper side is green and the lower side is whitish.

Inflorescences appear from the tip, 7-10 heads, up to 80 cm long and milky white in color. The fruit has a diameter of 1.5 cm and is covered with reddish brown scales. Seeds have a diameter of 1 cm. The flowering season is June-August and the fruit season is until December. This plant dies immediately after bearing fruit.

This plant produces brown to reddish brown rattan sticks, large and hard. The sap is drunk or rubbed on the body to treat fever. The sap is cooked to treat wounds. Edible fruit and flower panicles for decoration.

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 ...

Purwaceng (Pimpinella pruatjan)

Purwaceng or purwoceng or antanan gunung or Viagra of Java ( Pimpinella pruatjan or Pimpinella priatjan ) are small termas growing horizontally in Apiaceae, growing in villages on Dieng Plateau, Central Java Province, Indonesia, at 1,500 to 2,000 meters above sea level, the roots have medicinal properties for aphrodisiacs and are usually processed in powder form for a mixture of coffee or milk. P. pruatjan grows flat on the ground but does not propagate, small leaves are reddish green for 1-3 cm in diameter. This plant is only found in Java and grows in high mountain areas. A low population where industrial demand is very high results in increasingly scarce. Another place that is likely to become a purwaceng habitat is the Iyang Mountains and the Tengger Mountains in East Java Province. Efforts to multiply and cultivate have a big problem where these plants have difficulty producing seeds. In vitro propagation research through tissue cultivation has been carried out to overcome ...
