Paperbark (Melaleuca leucadendra)

Kayuputih or broad leaved paperbark or long-leaved paperbark or white paperbark (Melaleuca leucadendra) is a species of plant in the Myrtaceae, a large tree, growing to more than 20 meters long, branching, trunk covered with thick bark, white, papery, peeling, flowering almost any time of the year.

M. leucadendra has young leaves and branches covered with fine, short hairs, white when young but glabrous when mature. The leaves are alternately arranged, 75-270 mm long, 6.5-40 mm wide, flat, narrow round or lance-shaped, often curved or sickle-shaped, pointed tip and 5-9 veins.

The flowers are spike-shaped, white or cream or greenish at the tips of the branches that continue to grow after flowering, sometimes on the sides of the branches or in the axils of the upper leaves. Each spike is up to 35 mm in diameter, up to 80 mm long and contains 7-22 flower clusters in three sections.

The petals are 3-4 mm wide and fall off as soon as the flowers open. The stamens are arranged in five bundles around the flower and each bundle contains 5-12 stamens. The fruit is capsule-shaped, woody, 3.9-4.9 mm long, in loose clusters along the stem.

The bark is used to build waterproof huts, wrap food before it is cooked in the oven, wrap dead bodies. Very large tree trunks are used to make canoes. The leaves are used to treat respiratory tract infections. Flowers for making sweet drinks.

Various essential oils can be distilled. The two most common chemotypes are based on methyl eugenol and E-methyl isoeugenol.

Dry Valleys on Antarctic continent is the driest place in the world

The Sahara Desert is the largest desert in the world, rainfall is very low, only stretches of sand and rocks without rivers and plants further strengthen the view of drought. However, it turns out that the place is not the driest place in the world. Dry Valleys in Antarctica, although the continent is covered in ice, but has one part that is completely dry. Although the average rainfall in most of the Sahara Desert is less than 20 millimeters per year, there are still drier places. Dry Valleys in Antarctica is much drier where the average rainfall is 0 millimeters per year and gets the title of the driest place in the world. The valleys have so low humidity that there is almost no ice. This is the largest ice free place on the Antarctic continent. The area is surrounded by mountains that block ice from flowing into the valley. Drought is also caused by strong katabalic gusts from mountain peaks where cold air blows down the hill due to gravity. The wind has speeds of up to 322 k...

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 ...

Tripa tiger moth (Nannoarctia tripartita)

Tripa tiger moth ( Nannoarctia tripartita ) is an animal species in the Erebidae, a moth with a forewing length of 14-18 mm, predominantly black or dark brown with white and orange hues, thick fur on the dorsal surface, long legs and antennae, living in forest scrub and agricultural land. N. tripartita in females has forewings 15-18 mm long, black or dark brown with slightly oblique transverse and few spots. The hind wings are yellow with large dark discal points and three other dots. Males have forewings 14-17 mm long, black or dark brown with transverse oblique postdiscal bands and several spots. The hind wings are yellow with brown costal margins, discal confluent points, wide ridges on the crest and angular points in the tornus. The head has a thin orange pattern and a pair of long black antennae. Long legs are black. Tripa tiger moths live in forest scrub, farmland and roadsides. More stationary by sticking to the leaf surface at the top. Kingdom: Animalia Phylum: Arthropod...
