A midst the hustle and bustle in one of Chennai’s busiest streets, Chrompet, 51-year-old S Sathyanarayanan has created a green paradise on his 1,200 sq ft terrace. He grows 400 plants including ornamental flowers such as moss roses, medicinal plants like moringa, fruits like figs, and vegetables like lady’s finger, potatoes and more.

However, what’s unique about Sathya’s garden is that he prepares a variety of liquid fertilizers using kitchen ingredients to nourish his plants. Further, he also prepares a mix of water, jaggery, and an organic Waste Decomposer (WDC) solution in a 250-litre drum. This is fed to all plants regularly, which ensures healthy and pest-free growth.

“I started terrace gardening in 2015 after my family and I moved into our newly constructed home here. Earlier, we were living on the ground floor of a rented home and I could not grow many plants, as the availability of space was an issue. I started my gardening journey with 50 pots of money plants, tulsi, tomatoes and others. Today, my garden has over 400 pots, which grow ornamental flowers, fruits, and vegetables,” says Sathya, adding that regular visitors to his garden include buzzing honey bees and chirping love birds.

When Dong-Fang Deng and her students make feed for the fish they raise at UWM’s School of Freshwater Sciences, they often use ground fishmeal—dried fish parts from fisheries or wild catch—as the protein source.

It’s possible to find microplastics in commercial fish food, she said, because the wild fish that end up in fishmeal consume some of the microplastics that litter the waters they live in. But after Deng actually spotted tiny plastic beads in pre-ground fishmeal, it prompted a question.

“We wondered, ” If the fish eat the microplastics, could the particles accumulate inside their bodies?’” said Deng, professor of freshwater sciences who researches the role of diet in fish farming, or aquaculture.

Graphene electronic tattoos are unique devices used in healthcare systems for personalized applications. Monolayered graphene electronic tattoos are used to monitor different electrophysiological signals in humans. Despite their innovative functionality, these devices suffer from an impermeability to sweat and difficulties in reproducibility.

In an article recently published in the journal npj 2D Materials and Applications, an enhanced version of graphene electronic tattoos was introduced. This update is wearable on the skin with sweat permeability, superior electrical properties, and robustness. While the older systems suffered scattered electrical properties due to growth or transfer-related discrepancies, the reported graphene electronic tattoos with graphene nanoscrolls (GNS) or multilayered graphene structures showed enhanced properties.

A DEADLY virus that kills 30 per cent of those it infects by making them bleed from the eyes has reached Spain after a man was hospitalised last week.

The man in the city of Leon, in Spain’s North West, was diagnosed with Crimean-Congo haemorrhagic fever (CCHF) after being bitten by a tick.

The unnamed patient was hospitalised last week in Leon before being airlifted to another hospital by the Ministry of Defence on Thursday.
