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.

A deep-sea isopod Bathyopsurus nybelini adapted to feed submerged Sargassum algae

NEWS - Incredible footage shows a marine species, Bathyopsurus nybelini , feeding on something that sinks from the ocean’s surface. Researchers using the submersible Alvin found the isopod swimming 3.7 miles down using its paddle-like legs to catch an unexpected food source: Sargassum. Researchers from Woods Hole Oceanographic Institution (WHOI), the University of Montana, SUNY Geneseo, Willamette University and the University of Rhode Island found the algae sinking, while the isopod waited and adapted specifically to find and feed on the sinking nutrient source. The Sargassum lives on the surface for photosynthesis. The discovery of a deep-sea animal that relies on food that sinks from the waters miles above underscores the close relationship between the surface and the deep. “It’s fascinating to see this beautiful animal actively interacting with sargassum, so deep in the ocean. This isopod is extremely rare; only a handful of specimens were collected during the groundbreaking Swedis...
