Roseleaf bramble (Rubus rosifolius)

Roseleaf bramble or wild raspberry (Rubus rosifolius) is a thorny subshrub in Rosaceae, grows in tropical highlands, producing red berries, rose-like leaves with serrated margins and hair on both sides, white flowers in panicles and solitary.

R. rosifolius has woody stems with thorns like roses. Fruit sometimes called "bramble fruit" is an aggregate of drupelet, 2 cm long and can be eaten. The fruit tastes sweet and delicious when planted with good soil moisture.

Leaves in panicles with three to six itches facing each other with a leaf at the end. Elongated leaves with pointed tips, wavy with bones and have jagged edges. White flowers have five strands with white middle threads.

Roseleaf bramble is rarely cultivated, although it has several uses. Green leaves contain essential oils and are used as a tea to treat diarrhea, menstrual pain, morning sickness and childbirth.

This plant grows in the tropical highlands in primary forests, secondary forests, slopes and road sides in moist areas. The plant is considered an environmental weed and grows fast throughout the year even though it is not doused by rainwater.

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 ...
