Garden balsam (Impatiens balsamina)

Balsam or rose balsam or touch-me-not or spotted snapweed or garden balsam (Impatiens balsamina) is a plant species in the Balsaminaceae, annual plant, fibrous roots, 20-75 cm high, stems thick but soft, cylindrical, bright green or red and has many branches.

I. balsamina has leaves arranged spirally, oblong-ovate in shape, 2.5-9 cm long, 1-2.5 cm wide, scalloped edges, sharp tip, a main vein in the center with many small veins pinnate and green.

Flowers are bright red or red or mauve or purple or lilac or white, 2.5-5 cm in diameter and have long stalks. The seed capsule is elliptical in shape, green in color and has white hair. The mature seed capsule undergoes explosive dehiscence. Flowers are pollinated by bees, insects and nectar-feeding birds.

Various parts of the plant are used as traditional medicine for rheumatism, broken bones, constipation, gastritis and skin diseases. The juice from the leaves is used to treat warts, snake bites and fish poison. Flowers are used for burns. Plant extracts to stimulate hair growth.

The seed pods are active against antibiotic-resistant strains of Helicobacter pylori. It is also an inhibitor of 5α-reductase, the enzyme that converts testosterone to dihydrotestosterone (the active form of testosterone), thereby reducing the action of testosterone in the body.

The leaves are crushed to color the nails. The flowers are ground and mixed with alum to produce an orange dye that can be used to color semi-permanent nails, so colored nails must grow over time to remove traces of the color.

Naphthoquinones lawone or hennotannic acid, lawone methyl ether and methylene-3,3'-bilawsone are some of the active compounds in the leaves. It also contains kaempferol and some of its derivatives. Baccharane glycosides have been found in Chinese herbal medicine made from the seeds.

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 ...

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...
