Kemitip (Austroeupatorium inulifolium)

Kemitip (Austroeupatorium inulifolium) is a plant species in Asteraceae, perennial shrub, 1-5 m tall, cylindrical stems that are erect and branched, young green stems are covered with thick short hair, whereas old stems are brown and woody.

A. inulifolium has a facing leaf, elongated triangle with an elliptical base and a sharp tip, 7-18 cm long, 2.5-8 cm wide, green, a main bone in the middle with minor pinnate bones and a long stem 0.5-3 cm.

The flower has a head with a diameter of 2-3 mm, a length of 5-6 mm, arranged in a large corymb terminal, each head consisting of 3-4 involucral brackets that cover 10-15 creamy white, florets have a corolla for a length of 4-5 mm and fragrant.

Seeds ride on winds to spread and grow quickly to colonize vacant land, curbside, agricultural areas, natural forests, plantations, grasslands, riparian zones, disturbed land, shrubs, waterways, wetlands, open slopes and moist areas on altitude 100-2000 m.

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 ...
