Coffee (Coffea arabica)

Kopi gunung or mountain coffee or arabica coffee (Coffea arabica) is a plant species in Rubacea, up to 9 meters high, growing at an altitude above 700 meters above sea level, one of the most economically valuable plantation commodities among other plants.

C. arabica generally blooms after 2 years of age. Adult flowers pollinate with the opening of the petals and crown that will develop into fruit. Green skin will turn yellow and dark red with maturation. The entire process to harvest takes 6-8 months.

Flowers bloom at the beginning of the dry season and the fruit is ready to be picked at the end of the dry season. Primary branches will elongate and form new leaves at the beginning of the rainy season and prepare to produce flowers at the beginning of the upcoming dry season. The main stem has segments where a pair of opposite leaves grow.

Leaves have a line in the middle and lines to the side following the bone, wavy, thick green, muscular and tapered at the tip. The leaves grow and are arranged side by side in the armpits of branches and twigs. A pair of leaves is located in the same plane in the stem and twigs that grow horizontally.

Flowers are arranged in groups, each 4-6 buds and each leaf armpit produces 2-3 flower groups. The crown is white and fragrant. Green petals, base covering the ovaries containing two ovules. Stamens consist of 5-7 short stems.

The fruit has a length of 12-18 mm, light green then turns dark green, yellow, red and dark red to ripen. The fruit consists of exocarp, mesocarp, endocarp, epidermis and seeds. Old Mesokarp will be slimy and sweet. Mature seeds are white and hard.

Many varieties of arabica coffee are developed in the world to suit certain environments. The Indonesian Coffee and Cocoa Research Center recommends six varieties: Kartika 1 (1.8 tons/ha), Kartika 2 (1.9 tons/ha), Abesiania 3 (0.7 tons/ha), S795 (1.2 tons/ha), USDA 762 (1.2 tons/ha) and Andungsari 1 (1.9 tons/ha).

Elephant bell gourd (Trichosanthes tricuspidata)

Elephant bell gourd ( Trichosanthes tricuspidata ) is a plant species in the Cucurbitaceae, stems grow elongated to propagate or climb, many branches, cylindrical in shape and green in color. T. cochinchinensis has stem tips or branches that twist to attach themselves to a support or other plant. It grows to climb to cover a support, usually on another plant, up to several meters and creeps along the ground to reach another support. Arrow-shaped leaves, split base, sharp apex and two wings at an acute angle, have many veins ending at a sharp edge, green and have a long petiole. Single flower is white. The fruit is round to oval, ends with a tail, young green and turns red with maturity, thin skin, thick flesh and reddish yellow, has a short stalk and hangs. The seeds are in the middle of the fruit. Seeds are white, oval and flat. Black coated seeds. Elephant bell gourd grows wild in primary and secondary forests, agricultural land, roadsides, watersheds, especially on slopes, damp a

Yellow fever mosquito (Aedes aegypti) use thermal infrared to navigate hosts

NEWS - Aedes aegypti transmits the viruses that cause dengue, yellow fever, Zika and other diseases every year, while Anopheles gambiae transmits the parasite that causes malaria. Their capacity to transmit disease has made mosquitoes the deadliest animals. Moreover, climate change and global travel have expanded the range of A. aegypti beyond tropical geography. The mosquitoes are now present in subtropical climates that were previously unheard of just a few years ago. Male mosquitoes are harmless, but females need blood for egg development. There is no single cue that these insects rely on to feed; they integrate information from many different senses across a wide range of distances. " A. aegypti very adept at finding human hosts. This work provides a new insight into how they achieve this. Once we got all the right parameters, the results were clear and undeniable," says Nicolas DeBeaubien of the University of California at Santa Barbara UCSB. The researchers added

Banded dragonfish (Akarotaxis gouldae) diverged from Akarotaxis nudiceps 780,000 years ago

NEWS - A new species of dragonfish, Akarotaxis gouldae or banded dragonfish, off the western Antarctic Peninsula by researchers at the Virginia Institute of Marine Science at Gloucester Point, the University of Oregon at Eugene, and the University of Illinois at Urbana-Champaign, highlights the unknown biodiversity and fragile ecosystems of the Antarctic. A. gouldae was named in honor of the Antarctic Research and Supply Vessel (ARSV) Laurence M. Gould and crew. The larval specimen was collected while trawling for zooplankton and was initially thought to be the closely related Akarotaxis nudiceps hundreds of thousands of years ago. DNA comparisons with A. nudiceps specimens held in collections at the Virginia Institute of Marine Science, Yale University, and the Muséum national d’Histoire naturelle in Paris showed significant variation in mitochondrial genes that suggested the larval sample was a distinct species. Andrew Corso of the Virginia Institute of Marine Science and colle

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
