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[…]

Smarter routers and processors for better communication systems

Smarter routers and processors for better communication systems

A team of physicists has developed a new way to control the paths of light beams trapped in liquid crystals using laser beams and external magnetic fields1. This magneto-optical control will aid in developing efficient and robust signal processing methods for optical communication systems. “Our method can replace some important elements in the optical communicationRead more about Smarter routers and processors for better communication systems[…]

Liquid biopsy to hunt down deadly tumours

Liquid biopsy to hunt down deadly tumours

Researchers have developed a system that can detect, capture and remove tumour cells circulating in the peripheral bloodstream, making it potentially useful for diagnosing and treating cancers. Primary tumours shed cells which circulate in the bloodstream, eventually forming masses in organs, a process known as metastasis. Circulating tumour cells are promising cancer biomarkers. Using magneticRead more about Liquid biopsy to hunt down deadly tumours[…]

Cheetahs’ journey towards extinction

Cheetahs’ journey towards extinction

Human activities such as overhunting and deforestation have been leading to the extinction of many animal species. Now, it seems that humans are accelerating the decline of global cheetah populations, pushing the world’s fastest land animal towards the edge of extinction. Analysing global cheetah populations, an international research team comprising researchers from the United Kingdom,Read more about Cheetahs’ journey towards extinction[…]

Healing skin wounds using bamboo cellulose nanocrystals

Healing skin wounds using bamboo cellulose nanocrystals

Nanobiocomposites made of bamboo cellulose nanocrystals and silver nanoparticles can accelerate healing of skin wounds in mice, new research shows1. These nanocomposites could be converted to films and ointment, useful as wound-healing dressing material. Existing wound-dressing materials have drawbacks such as foul smell, low porosity and poor-healing capacity. Some are also toxic to biological cells.Read more about Healing skin wounds using bamboo cellulose nanocrystals[…]

Silk protein for scar-less healing

Silk protein for scar-less healing

Researchers have synthesized antibiotic-coated nanofibrous mats that can be used as material to dress and heal wounds caused by disease-related foot ulcers and various infections1. Chronic wounds like diabetic foot ulcers, venous ulcers and pressure sores affect millions globally. Such wounds are difficult to heal and sometimes necessitate amputations. To find an alternative dressing materialRead more about Silk protein for scar-less healing[…]

New maps show where to park spacecrafts on the Moon

New maps show where to park spacecrafts on the Moon

Detailed maps of lunar surface which will help identify sites where future missions can land have been created by astrophysicists who analyzed microwave emissions and surface temperatures1. Microwave remote sensing doesn’t require sunlight, making it suitable for monitoring surface features of remote targets such as planetary bodies. The researchers measured the microwave emissions of theRead more about New maps show where to park spacecrafts on the Moon[…]

A simple technique to fiddle with silver atoms

A simple technique to fiddle with silver atoms

Organic ions or molecules that bind to the surface of noble metal nanoclusters are known as ligands. Usually, these ligands are modified to allow for tailoring the nanoclusters leading to potential practical applications. So far, however, it has not been well understood how modifying the ligand alters the electronic and optical properties of the metalRead more about A simple technique to fiddle with silver atoms[…]

A brain chemical can combat depression

A brain chemical can combat depression

Astrocytes transport nutrients such as lactate to neurons. Lactate activates certain genes linked to neurons’ plasticity, particularly at the nerve junction known as synapse, contributing to the formation of long-term memory. When astrocytes’ population dwindles, lactate levels in the brain fall, causing neurons to malfunction and leading to brain disorders such as depression. Now, aRead more about A brain chemical can combat depression[…]
