Soapbush (Clidemia hirta)

Senggani bulu or soapbush or Koster's curse (Clidemia hirta) is a species of tropical plants, perennial shrubs, grows as high as 0.5-3 m, but sometimes reaches 5 m in more shady habitat, young stems are round and covered with hair, stiff, reddish brown.

C. hirta has simple leaves arranged opposite to the stem, oval-shaped in a wide line at the base with a pointed tip and almost entirely to a smooth jagged margin. The upper surface is rarely covered with hair, while the lower surface has thick hair.

The leaves have a rather tangled appearance and five main veins are straight, curved and spread in parallel from the base of the leaf to the tip. Minor veins spread transversely and straightly that connect the five main veins.

The flowers are arranged in small clusters at the ends of branches, growing on very short stems and having five white petals or sometimes pale pinks. The base of the flower is covered with a mixture of coarse and sticky hair, five sepals but these are very small and five stamens which have claw-like appearance.

Berries are round, up to 8 mm long and dark blue or purplish or blackish in color and are covered by stiff hair and spread especially when still young. Each contains more than 500 light brown seeds. The fruit has flavor and is edible.

Soapbush is widely introduced as an ornamental plant, very invasive in wet zones and inland forests at an altitude of 5-1300 meters especially attacking fissures in the forest and killing native species. Very fast to master wet grasslands, open grasslands, plantations, roadside, wet open forests, riparian zones, forest boundaries and rain forests.



Senggani bulu into flowering and fruit throughout the year to produce more than 1,000 fruits/year with 700,000 seeds. Seeds can remain alive in the soil for at least 12 years. Seeds are spread by birds, wild pigs, other animals and humans.

Fruit contains 49 cal calories, 84.5% H2O, 1.9 gr protein, 0.1 gr fats, 12.3 gr carbohydrates, 1.2 gr fiber, 0.0172 gr calcium, phosphorus, 0.57 gr, iron 0.029 gr, B-carotene, 3 gr, and 0.14 gr ascorbic acid.

The tannins in the fruit are poisonous to goats but are not harmful to humans. The fruit extract is processed into a delicious and beautiful tilapia blue syrup and can be used to increase and eliminate the bitterness of tea. The leaves are used to treat skin infections of Leishmania braziliensis.

Active substances contained in leaves that act as wound healers are flavonoids that function as antibacterial and antioxidants, steroids function as anti-inflammatory, saponins have the ability as an antiseptic, and tannins function as astringents.

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 ...

False nettle (Boehmeria cylindrica)

False nettle ( Boehmeria cylindrica ) is a species of plant in the Urticaceae family, a herb or small shrub, up to 160 cm tall, usually monoecious but rarely dioecious. The leaves are paired or alternate, and the inflorescence is a spikelet with a cluster of small bracts at the tip. B. cylindrica generally grows to a height of 50-100 cm. Spine-like hairs form in the leaf axils. The leaves are oval and up to 10 cm long and 4 cm wide. The flowers are green or greenish-white and emerge from the upper leaf axils. Male and female flowers usually grow on separate plants. Male flowers are more numerous among the spikes in clusters. Female flowers are less evenly distributed along the spikes. The small, oval seeds are covered with small, hook-like hairs. Ripe seeds are dark brown. The inflorescence resembles a spike and is up to 3 cm long. This species can be found in moist to mesic deciduous forest habitats, growing abundantly along streambanks, floodplains, and lowlands. B. cylindrica is ...
