Shampoo ginger (Zingiber zerumbet)

Lempuyang or shampoo ginger (Zingiber zerumbet) is a plant species in Zingiberaceae, a spice with leafy stems, grows up to 1.2 m tall, grows wild in the shade, rhizomes are used as food flavoring and appetizers in various dishes, rhizome extract is used in treatment.

Z. zerumbet in the dry season undergoes a period of inactivity on the soil where the leafy stems wither and die, leaving pale brown rhizomes that crawl across the soil surface. The stems will grow back and produce flowers in the rainy season.

Leaves 10-12 fins with pointed tips, 15-20 cm long, grow in alternating arrangements on thin, erect stems to 1.2 m high. Flower heads grow between stems. Flowers are conical, have stick-shaped stalks, erect, separate from the stem and shorter.

The flower heads are green and turn red, 3-10 cm long with overlapping scales, covering the small yellowish white flowers poking out. Mature flowers gradually fill with an aromatic and slimy liquid.

The rhizomes, leaves, petioles and flowers have a fragrant aroma. Often used to enhance the taste of meat and fish when cooked. The rhizomes are sliced, dried, and ground into a powder. The gel on adult flower heads is used to soften and make hair shiny.

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 ...
