Porcupine flower (Barleria prionitis)

Landep or porcupine flower (Barleria prionitis) is a species of plant in the Acanthaceae, shrub, branched, up to 1.8 meters high, lower leaf axils have spines 1-2 cm long, stems and branches terete, smooth, lenticels and glabrous.

B. prionitis has elliptical to ovate leaves, 4-10.5 cm long, 1.8-5.5 cm wide, both surfaces pubescent when young but soon become glabrous.

Flowers are golden yellow, clustered in the axils of the upper leaves or in the bracts. Apical spinous calyx lobes and crown are yellowish to orange in color.

Porcupine flower grows on forest floors, meadows, plantations, roadsides, shrubs and dry places with elevations up to 600 meters.

This plant is used in traditional medicine to treat whooping cough and tuberculosis, infected wounds, toothache, ulcers and swollen glands, rheumatism and prevent maceration.

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...

Yellow potter wasp (Delta campaniforme)

Yellow potter wasp ( Delta campaniforme ) is a species of animal in Vespidae, solitary wasp, shiny yellow, shiny black, dull black and brown with a yellow striped belly, a long and narrow waist, a nest built using mud and a circle attached to a cliff. D. campaniforme has a black head with a yellow plot in the center and two transverse plots on the right and left. A pair of black eyes. A pair of antennas, long, yellow with a black base and tip. The back is yellow and black. A large black plot semicircle at the top of the front. The two plots form a circular line at the top of the back. A pair of wings is brownish black and transparent. The stomach has the shape of a water droplet, pointed tip, black with yellow and black segments, alternating to form stripes. Linear folds on the sides. The underside of the front is brown and large. The middle section has alternating yellow and black segments that form stripes. The stomach and back are connected by a long, narrow, downward curved pipe...
