Lawe (Abroma augustum)

Lawe or devil's cotton (Abroma augustum) is a plant species in Malvaceae, a small tree or bush that is erect, up to 10 m tall but generally 2-3 m tall, stems and twigs covered with star hair that are sharp, brittle and cause skin itching, sometimes also with glandular hair.

A. augustum has a single leaf, alternating, has a long stalk, a heart-shaped base, a pointed tip with a very variable base whose leaves near the base of the branch have a circular shape from the egg to the heart, 3-5 curves, diameter 20-37 cm, while the leaves near the tips of twigs have elongated shapes with smooth toothed edges.

The flowers gather in cymes at the tips of the twigs or face leaves, 1-4 buds, 1-3 cm long stems and 6-8 mm bractea. Hanging flowers, 3-5 cm in diameter, 5 angles and 1-3.5 cm long stems. The petals have 5 leaves, share a deep, triangular, 15-20 mm long, 6 mm wide and greenish.

The crown has 5 leaves, spoon-shaped, 2-3.5 cm long, 1 cm wide, dark purple or red or yellow, concave and white base, drooping and hanging. Stoneware-shaped stamens, 15 anthers that alternate between 3 anthers and 1 staminodium.

Square fruit, bell or cone upside down, have 5 wings, have a beak or not, the edges are broken showing space, the sides divide according to the bulkhead, 4-5 cm long and 3-4 cm wide. Cylindrical or breech-shaped seeds, 3-4 mm long, 2 mm wide and black.

Lawe grows wild along the water's edge, jungle bush, secondary forests, abandoned lands, the edge of the village, the edges of the road and railroad and open areas at an altitude of 0-1100 m, daily temperature of 27-30C in the month the hottest and minimum rainfall of 1500 mm/year.

Devil's cotton is widely cultivated for stems that produce fine fibers to be spun into clothing, fishing lines, fishing nets, hammocks and rope. The very fine fibers are painted and arranged as wigs.

Roots, stems, leaves and other parts produce medicinal ingredients to treat menstrual disorders, aphrodisiacs, anti-fertility, diabetes, cure gonorrhea, skin diseases and scabies. This species is sometimes planted as ornamental shrubs.

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 ...

Alexandrian Laurel (Calophyllum inophyllum)

Alexandrian Laurel ( Calophyllum inophyllum ) is a species of plant in the Calophyllaceae family. It is a low-branching, slow-growing, spreading tree with a wide, irregular crown. It grows up to 30 meters tall, has a cylindrical trunk, and thick, black, and fissured bark. The leaves are thick, oval, with rounded tips, even margins, and a smooth surface. The upper side is dark green and glossy, the underside is bright green, with a central vein in bright green. The leaves are up to 27 cm long, 13 cm wide, and have a 1 cm petiole. Flowers bloom throughout the year, but typically from April to June and October to December. Flowers are 30 mm in diameter and occur in racemose or paniculate inflorescences of four to 15 flowers. The flowers have a sweet aroma and attract numerous pollinating insects. The fruit is round, green, up to 4 cm in diameter, with a large seed in the center. When ripe, the fruit wrinkles and turns yellow to brownish. The fruit is light, with thin, spongy flesh and a...
