JNCASR researchers have synthesised a molecule that shows high antibacterial activity against multidrug-resistant Acinetobacter baumannii. The molecule has no toxicity to human cells. It is effective against A. baumannii bacteria that is dormant as well. A novel molecule developed by chemically linking (conjugate) an amino acid (glycine) to a polymer has been found to possess … Continue reading JNCASR’s molecule effective against multidrug-resistant Acinetobacter baumannii

JNCASR finds a key protein conferring radiation sensitivity in cancer cells
JNCASR researchers have unravelled the molecular mechanism by which autophagy pathway gets enhanced leading to human cells becoming resistant to radiation. When PC4 protein is absent or downregulated, autophagy gets enhanced and cells become resistant to radiation. The medical implication of the finding will be in treatment of certain cancer patients. Researchers at the Jawaharlal … Continue reading JNCASR finds a key protein conferring radiation sensitivity in cancer cells
JNCASR’s molecule improves recovery after spinal cord injury
JNCASR researchers used a small molecule conjugated to carbon nanospheres to activate an enzyme (Cbp) that promotes axon regeneration and recovery after spinal cord injury. Regeneration and growth of axons led to recovery of sensory and motor functions in the animals with spinal cord injury. Mice could walk normally on the floor without limping and … Continue reading JNCASR’s molecule improves recovery after spinal cord injury
200 scientists sign an appeal to ‘vote against inequality, intimidation, discrimination’
For the first time, a large number (199) of scientists, both senior and young, have signed an appeal to vote against hate politics. The appeal calls for people to vote so as to “reject those who lynch or assault people, those who discriminate against people because of religion, caste, gender, language or region. Again, we must … Continue reading 200 scientists sign an appeal to ‘vote against inequality, intimidation, discrimination’
JNCASR team fully restores long-term memory in mice with Alzheimer’s
JNCASR researchers along with French counterparts have been able to fully restore neuron to neuron connections and long-term memory in mice with Alzheimer’s disease using a small molecule that activates two enzymes. The molecule attached to carbon nanospheres was able to breach the blood-brain barrier and reach the brain in sufficient concentration. Using a small … Continue reading JNCASR team fully restores long-term memory in mice with Alzheimer’s
JNCASR team develops novel material to convert waste heat into electricity
JNCASR scientists have developed a novel material — silver copper telluride — that can be used as a thermoelectric material as it has poor thermal conductivity but good electrical conductivity. With a calculated efficiency of 14%, the new material can be used for converting waste heat into electricity. A novel compound that exhibits poor thermal conductivity in … Continue reading JNCASR team develops novel material to convert waste heat into electricity
JNCASR researchers add more security to LiFi
Researchers from JNCASR have added another layer of security to LiFi by coating the walls with phosphorescent paint. The phosphorescent paint absorbs light and randomly emits photons, which ultimately scrambles the signal by superimposing a larger noise component to the signal. Jamming the signals can even prevent usage. Like WiFi, the light-fidelity (LiFi) technology that uses both visible … Continue reading JNCASR researchers add more security to LiFi
Bengaluru researchers mimic nature to produce richer colours
In a novel approach that mimics nature, Bengaluru-based researchers have designed crystalline materials that selectively scatter specific colours of light. Dyes and pigments produce colour predominantly through selective absorption of light. But scattering of light by particles which are arranged in an ordered, periodic pattern produces structural colour, which gives butterfly wings their colour and … Continue reading Bengaluru researchers mimic nature to produce richer colours
Indian researchers use bacteria to power a tiny engine
Researchers from Bengaluru’s Indian Institute of Science (IISc) and the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) achieved a major breakthrough when they designed a microscopic heat engine that operates at 50-60 per cent efficiency by relying on changes in bacterial activity. The results were published on August 29 in the journal Nature Physics. … Continue reading Indian researchers use bacteria to power a tiny engine
