Andaman’s new taste is sweet-and-sour

Edible wild banana species discovered, the second such on the island in two years.

Botanists in the Andaman and Nicobar Islands have been quietly going bananas. And it is not their fault, for the islands are a biodiversity hotspot that hosts seven different species of wild banana that we know of, not to mention numerous, as yet undocumented, others.

The latest discovery, published in the Nordic Journal of Botany, is of a species of wild banana named Musa paramjitiana, in honour of Paramjit Singh, who happens to be the director of the Botanical Survey of India (BSI). The species was found in North Andaman’s Krishnapuri forest, 6 kilometres from any human habitation.

The plant grows to a height of nine metres and bears an edible, sweet-and-sour tasting fruit that is boat-shaped and has numerous bulb-shaped seeds. Its conservation status has been declared as ‘Critically Endangered’ as it has so far been spotted in only two locations on the islands, each with 6 to 18 plants in a clump.

According to Mr Lal Ji Singh(a BSI scientist),who made the discovery, the fruit is part of the diet of local tribes. “The fruits and seeds have ethnomedicinal importance. Pseudo-stem and leaves of these species are also used during religious and cultural ceremonies,”

“These discoveries present a great opportunity for plant breeders and horticulture experts to improve the existing banana crop. The germplasm of all the wild banana species needs to be conserved on an urgent basis since most of these are found in very small habitats and at risk of extinction,”
In 2014, he discovered Musa indandamanensis, another wild banana, in a remote tropical rainforest on the Little Andaman island. It has dark green cylindrical flower buds.

Chemical from turmeric helps treat cancer in children

Scientists in the U.S. have found yet another use for curcumin, the bioactive component of turmeric that is widely used in Indian cuisine, this time to treat cancer in children. Researchers at Nemours Children’s Hospital and the University of Central Florida (UCF) have found that nanoparticles loaded with curcumin can target and destroy neuroblastoma tumour cells. Children aged five or less are most commonly affected.
In their study, the researchers attached curcumin to cerium oxide nanoparticles and tested the nano-curcumin formulation in cell lines of a high-risk form of neuroblastoma.
This formulation induced substantial cell death in neuroblastoma cells while producing no or only minor toxicity in healthy cells,” says the report published in Nanoscale . Curcumin has been shown to have substantial anti-cancer ability, but its low solubility and poor stability have restricted its use in therapeutic applications. The study demonstrates a treatment method “without the toxicity of agressive therapy” and shows that nanoparticles can be “an effective delivery vehicle” for cancer drugs, said a statement from UCF.
