Sweetsop (Annona squamosa)

Srikaya or sweetsop (Annona squamosa) is a plant species in the Annonaceae, a small tree or shrub, branched, 3-8 meters high, highly adaptive to soil type and elevation, producing edible fruit with sweet, whitish and watery flesh.

A. squamosa has light brown branches with leaf scars and a bright yellow interior. Twigs turn brown with light brown lenticels.

Leaves are thin, simple, alternate, 5-17 cm long, 2-6 cm wide, rounded base and tapered tip. Pale green on both surfaces. The leaf stalks are 0.4-2.2 cm long and green in color.

Flowers solitary or in short lateral clusters, 2.5 cm long, yellow-green on peduncles 2 cm long. The three outer petals are green, purplish at the base, oval, 1.6-2.5 cm long and 0.6-0.75 cm wide.

The stamens are numerous, white, less than 1.6 cm long and the ovaries are light green. Each pistil forms a separate tubercle, generally 1.3-1.9 cm long and 0.6-1.3 cm wide.

Soft fruit aggregates formed from many carpels, loose and almost free. grow and mature. The fruit is heart-shaped, yellow-green, 5-10 cm in diameter with many rounded protrusions and covered with flour.

The flesh is yellowish-white, edible and sweet-scented. Each carpel contains an oval seed, shiny and smooth, dark brown to black and 1.3-1.6 cm long.

Srikaya requires a tropical or subtropical climate with summer temperatures of 25-41C, moderate drought tolerance, 700 millimeters (28 inches) of annual rainfall and will not produce well during droughts. It grows at elevations of 0-2000 meters and does well in hot dry climates.

The leaves are boiled to treat dysentery and urinary tract infections. The leaves are pounded as a poultice and rubbed on the wound. The leaves were rubbed on the floor and placed in the hens' nests to keep fleas away. The fruit is eaten fresh or processed into juice.

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 ...

Dry Valleys on Antarctic continent is the driest place in the world

The Sahara Desert is the largest desert in the world, rainfall is very low, only stretches of sand and rocks without rivers and plants further strengthen the view of drought. However, it turns out that the place is not the driest place in the world. Dry Valleys in Antarctica, although the continent is covered in ice, but has one part that is completely dry. Although the average rainfall in most of the Sahara Desert is less than 20 millimeters per year, there are still drier places. Dry Valleys in Antarctica is much drier where the average rainfall is 0 millimeters per year and gets the title of the driest place in the world. The valleys have so low humidity that there is almost no ice. This is the largest ice free place on the Antarctic continent. The area is surrounded by mountains that block ice from flowing into the valley. Drought is also caused by strong katabalic gusts from mountain peaks where cold air blows down the hill due to gravity. The wind has speeds of up to 322 k...

Tripa tiger moth (Nannoarctia tripartita)

Tripa tiger moth ( Nannoarctia tripartita ) is an animal species in the Erebidae, a moth with a forewing length of 14-18 mm, predominantly black or dark brown with white and orange hues, thick fur on the dorsal surface, long legs and antennae, living in forest scrub and agricultural land. N. tripartita in females has forewings 15-18 mm long, black or dark brown with slightly oblique transverse and few spots. The hind wings are yellow with large dark discal points and three other dots. Males have forewings 14-17 mm long, black or dark brown with transverse oblique postdiscal bands and several spots. The hind wings are yellow with brown costal margins, discal confluent points, wide ridges on the crest and angular points in the tornus. The head has a thin orange pattern and a pair of long black antennae. Long legs are black. Tripa tiger moths live in forest scrub, farmland and roadsides. More stationary by sticking to the leaf surface at the top. Kingdom: Animalia Phylum: Arthropod...
