Sensitive sensors could be made from spider silk fibre

Physicists have developed a way to help structurally modify spider silk fibre and microweld it with various metals and carbon-based materials1 — a method that could be useful for making various spider-silk-based microstructures such as ultrasensitive sensors. Spider silk is a tough and lightweight biomaterial. However, existing techniques that modify silk fibres using ultraviolet lightRead more about Sensitive sensors could be made from spider silk fibre[…]

Artificial intelligence helps measure sunlight

Artificial intelligence helps measure sunlight

A Saudi Arabian scientist has developed a new tool that can efficiently predict availability of solar rays at different locations in the kingdom and elsewhere in the Middle East. His model can help fellow scientists and solar operators make the best possible plans to harvest energy from the sun. This new software-based tool predicts theRead more about Artificial intelligence helps measure sunlight[…]

Artificial leaf for harnessing sunlight

Artificial leaf for harnessing sunlight

Using a nanocomposite, researchers have made a thin-film device that can absorb sunlight like a natural leaf and split water, making it potentially useful for generating hydrogen fuel1. Producing hydrogen by harnessing the Sun’s power depends on various factors such as light-absorbing efficiency, charge separation and migration in a photocatalyst. It is difficult to makeRead more about Artificial leaf for harnessing sunlight[…]

Glowing corals’ survival secrets unravelled

Glowing corals’ survival secrets unravelled

Corals in sunlit shallow waters usually glow because of specific proteins that block the sun’s harmful rays. But in dark, deep-water environments, instead of blocking sunlight altogether, those proteins help the corals absorb some light to make food with the help of an algae called zooxanthellae. This adaptation is how corals thrive at great depths,Read more about Glowing corals’ survival secrets unravelled[…]

Data on stolen mobile can be destroyed remotely

Data on stolen mobile can be destroyed remotely

Scientists have developed a tiny embedded system that could remotely destroy the memory of stolen or hacked electronic devices such as mobile phones, laptops and pen drives to prevent data theft1. “This system could be integrated with state-of-the-art high-performance silicon chips, making it potentially useful for protecting data in various fields such as intelligence, nationalRead more about Data on stolen mobile can be destroyed remotely[…]

A chemical trick that makes metal atoms emit light

A chemical trick that makes metal atoms emit light

Nanoclusters of metal atoms are promising for their fluorescence, low toxicity and stability under light. However, the underlying causes of these features have not been adequately scrutinized, something that a new research from Saudi Arabia and China is trying to change by studying the metal atoms under different light and heat conditions to fine-tune theirRead more about A chemical trick that makes metal atoms emit light[…]

Glowing quantum dots made from mango leaves

Glowing quantum dots made from mango leaves

By heating dried mango leaf extract, researchers have synthesized fluorescent graphene quantum dots that can be used for bioimaging and as intracellular temperature-sensing probes1. Existing fluorescent materials, such as organic dyes, metal clusters and quantum dots, are toxic to biological cells and unstable when exposed to light. In search of a biocompatible fluorescent material, scientistsRead more about Glowing quantum dots made from mango leaves[…]
