Katuk or sweet leaf or star gooseberry or Breynia androgyna (Sauropus androgynus) is a species of plants in Phyllanthaceae, clumping, growing chronic, 2-5 m tall, woody stems, tubular with leaf marks, widely used as living fences, vegetables and medicine.

S. androgynus has a taproot and is white. Stems upright, slender, few branches, young green and turn greenish brown with aging, if the tip of the stem is trimmed will grow new shoots that form branches.

Compound leaves, ovoid, pointed tip, blunt base, flat edge, 1-6 cm long, 1-4 cm wide, a bone in the middle, several pinnate veins, short stems, dark green in color with silvery features on the upper surface and bright green on the lower surface.

Compound flowers, umbrella-shaped and grow in the armpit of the leaf. Petals are ovoid and red-purple. Three pistil heads and shaped like a kidney. Three stamens and 5-10 mm stalk length.

Fruit will ride and purple. The fruit is round, a diameter of 1.5 mm and is whitish green. Each fruit has seeds, round, hard and black.

Katuk grows well at altitudes up to 1300 m, has tropical and subtropical adaptations, is productive throughout the year although it tends to be somewhat dormant in cold weather. Tolerant to heat, humidity, sensitive to cold and saline soil. Liked clay soils and pH 6.







Plants are widely used as living fences, shoots are used as asparagus, cooked leaves as vegetables, increase breast milk, treat acne, treat fevers, ulcers and inflammation of the esophagus. The leaves contain papaverina and if excessive can cause side effects such as poisoning.

Leaves contain energy (59.00cal), carbohydrate (11.00g), protein (4.80g), fat (1.00g), calcium (204.00mg), phosphorus (83.00mg), iron (2.70mg), vitamin A (10,371SI), vitamin B1 (0.10mg), vitamin C (239.00mg) and water (81.00g).

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 ...

Purwaceng (Pimpinella pruatjan)

Purwaceng or purwoceng or antanan gunung or Viagra of Java ( Pimpinella pruatjan or Pimpinella priatjan ) are small termas growing horizontally in Apiaceae, growing in villages on Dieng Plateau, Central Java Province, Indonesia, at 1,500 to 2,000 meters above sea level, the roots have medicinal properties for aphrodisiacs and are usually processed in powder form for a mixture of coffee or milk. P. pruatjan grows flat on the ground but does not propagate, small leaves are reddish green for 1-3 cm in diameter. This plant is only found in Java and grows in high mountain areas. A low population where industrial demand is very high results in increasingly scarce. Another place that is likely to become a purwaceng habitat is the Iyang Mountains and the Tengger Mountains in East Java Province. Efforts to multiply and cultivate have a big problem where these plants have difficulty producing seeds. In vitro propagation research through tissue cultivation has been carried out to overcome ...
