Polka dot plant (Hypoestes phyllostachya)

Polka dot plant (Hypoestes phyllostachya) is a plant species in Acanthaceae, a green shrub with a height of up to 30 cm, producing flowers, green leaves with white or pink or purple spots as if sprayed with paint and many cultivars have these features often blends into a larger color area.

The polka dot plant produces small purple flowers, solitary in a knot that resembles a honeysuckle, formed in a cob at the end of a stem and the fruit is a capsule. This plant most often grows partially in the sun.

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...

Cempaki (Termitomyces microcarpus)

Cempaki ( Termitomyces microcarpus ) is a species of fungus in the Lyophyllaceae family. It grows wild in tropical Asian forests near termite nests. It is rarely reported in urban areas. It is edible and known for its deliciousness, high nutritional value, and difficulty in cultivating. In Indonesia, it is used as an alternative food ingredient. T. microcarpus is the smallest of the Termitomyces species, umbrella-shaped, plain white, measuring 5 cm tall and 2.5 cm wide. It grows in dense clusters on surfaces and forms a mutualistic relationship, requiring the metabolic activity of termites as a substrate for growth. This species is known for its deliciousness, rich in nutrients, and has potential bioactive properties, such as helping lower cholesterol and acting as a tonic. Currently, it is difficult to cultivate on a large scale, and people rely solely on wild harvests. This mushroom is highly favored for its savory, delicious flavor and soft, chewy texture. It is often stir-fried ...
