Broad-leaved paperbark (Melaleuca quinquenervia)

Kayu putih buku or broad-leaved paperbark (Melaleuca quinquenervia) are small to medium sized trees in Myrtaceae, up to 20 m high, stems covered by thin white, cream, and gray paper skin. The leaves are arranged, flat, rough, spear-shaped, dull or green-gray, 55–120 mm long and 10–31 mm wide.

The flowers are packed in strands at the end of the branch and continue to grow after flowering, sometimes also in the upper leaf axils. Each strand contains 5 to 18 flower groups, diameters up to 40 mm and lengths of 20-50 mm. The petals are about 3 mm long and fall out when the flowers age.

Flowers are followed by woody fruits, shaped cylindrical capsules wide, 2.5-4 mm long and in groups. Each capsule contains many small seeds that appear every year. M. quinquenervia has proven to be a different chemical form and is widely used traditionally. Drinks are made from young aromatic leaves to treat colds, headaches, and common ailments.

Leaf oil from chemotype cineole is used externally for coughs, colds, neuralgia, and rheumatism. Nerolidol and linalool chemotypes are also cultivated and distilled on a small scale for fragrances. Bark like paper is used traditionally to make coolamons, shelter and wrap baked goods.

Nectar is traditionally extracted by washing in water and consumed as a drink. Scented flowers also produce yellow honey, very flavorful although not considered a high-quality honey but popular. Essential oils for various cosmetic products, antiseptic and antibacterial agents for bladder infections, respiratory problems and inflammation of the nasal mucous membranes.

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 ...

Petai (Parkia speciosa)

Stink bean or bitter bean or pete or petai ( Parkia speciosa ) is a tropical tree species in Fabaceae, 5-25 m high and branched, reddish brown bark, always green, compound and pinnate leaves, young seeds are harvested as fresh or boiled food . P. speciosa has a hump-shaped flower that hangs with a long stalk, usually appearing near the tips of the branches. Flowers that are young and not yet blooming are green, mature flowers have stamens and pistils, old flowers turn yellow and are large in size. Dozens of long, flat pod-shaped fruits emerge from a flower hump hanging from a tree. Each pod has up to 10-20 seeds that are neatly arranged, green when young and wrapped in a rather thick membrane of light brown. The fruit dries and becomes harder as it ripens and releases the seeds. Petai grows well in wet and slightly wet climates, low land to mountains with an altitude of 1,500 m, open spaces and lots of sun throughout the day with fine-tinted soil and Ph 5.5-6.5. Trees start bea...
