Minnieroot (Ruellia tuberosa)

Kencana ungu or pletesan or popping pod or minnieroot (Ruellia tuberosa) is a species of plant in the Acanthaceae, an upright herb, up to 2 meters high and has many branches. The leaves are oval, with a pointed base, blunt tip, thin, flat surface, green, flat edges and pinnate veins.

R. tuberosa has leaves up to 13 cm long, 7 cm wide and stalks up to 4 cm long. Trumpet-shaped flowers, 4-5 cm in diameter and up to 6 cm long. The thin crown is purple or blue, five strands and fused downwards to form a tube.

The fruit is tubular with a pointed tip and 2-3 cm long. Young fruit is green, old fruit is brown. If the ripe fruit is exposed to water it will burst, detach and be thrown from the stalk. The seeds are round, flat and brown. Minnieroot uses taproots and tubers.

This plant contains active chemical compounds including alkaloids, triterpenoids, flavonoids, phenolics, saponins, coumarin and quinone dyes. Roots contains apigenin and luteolin. Seed oil contains myristic, capril and lauric acid.

Traditional treatment uses R. tuberosa as an antidiabetic, antipyretic, analgesic, anti-hypertensive, anti-inflammatory and antioxidant. The leaves are ground into paste and used to treat wounds, itching, insect bites, venereal disease, wounds, tumors and rheumatic complaints.

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 ...

Takenoshin Nakai swallow-wort (Vincetoxicum nakaianum) replaces V. magnificum and C. magnificum

NEWS - Researchers reported an erect herbaceous species distributed in the eastern part of Honshu Island, Vincetoxicum magnificum (Nakai) Kitag. based on Cynanchum magnificum Nakai, nomen nudum. Therefore, they named this species Takenoshin Nakai swallow-wort ( Vincetoxicum nakaianum K.Mochizuki & Ohi-Toma). Vincetoxicum Wolf (Asclepiadeae) is the third largest genus in the Asclepiadoideae consisting of about 260 species geographically extending from tropical Africa, Asia and Oceania to temperate regions of Eurasia. A total of 23 species are known from Japan, including 16 endemic species. Molecular phylogeny divides Japanese Vincetoxicum into four groups: the “Far Eastern” clade consisting of 11 endemic species and 4 more widespread species, 1 sister species to the “Far Eastern” clade, the “subtropical” clade consisting of 2 species and the “Vincetoxicum s. str.” clade consisting of 5 species. V. magnificum (Nakai) Kitag. (Japanese: tachi-gashiwa) is closely related to V. macro...

Red costate tiger moth (Aloa lactinea)

Red costate tiger moth ( Aloa lactinea ) is an animal species in the Erebidae, a moth with a wingspan of 40 mm, a yellow belly, black antennae with red basalt joints, dark red palpi on the sides and white below, black terminal joints, living in forests and agriculture in the lowlands to mountainous areas. A. lactinea has a white head with a red stripe on the back. Thorax is white. The wings are predominantly white in color with black dots on each corner of the cells and a red margin. The wings have branched pulse lines and a starchy surface. The wing-covered upper abdomen is black with large elliptical plots and is colored yellow forming cells. The lower abdomen is white and has fine hairs that fall out easily. A pair of antennas is black. The forelegs are red, white and black. The other legs are white on the top and black on the bottom. The final joints are white and black which form alternating rings. Tip and sole black all over. The larvae are black in color with a lateral crest ...
