IISc professor has two papers retracted, three corrected for image issues

Two papers of Prof. Kithiganahalli N. Balaji from IISc have been retracted and three more have been corrected for issues with images, including duplication and undeclared gel splices. Two more papers of his have been listed on PubPeer website. On December 13, 2019, two papers of Prof. Kithiganahalli N. Balaji from the Department of Microbiology … Continue reading IISc professor has two papers retracted, three corrected for image issues

Combination therapy using malaria drug quickly clears TB

IISc researchers have discovered the mechanism by which TB bacteria develop tolerance to TB drugs. They found a combination of malaria and TB drug can prevent the bacteria from developing drug tolerance. The drug combination cleared TB bacteria from mice lungs in eight weeks. Researchers from Bengaluru have made an important discovery of the mechanism … Continue reading Combination therapy using malaria drug quickly clears TB

IISc: Natural shield protects certain DNA regions from radiation damage

IISc researchers found that certain regions of the genome rich in four-stranded DNA  — G-quadruplexes (G4-DNA) — are more resistant to radiation damage. As a result, there are fewer DNA breaks seen in G-quadruplexes when exposed to radiation. It is well known that ionizing radiation can break the double-stranded DNA in one or both the strands. … Continue reading IISc: Natural shield protects certain DNA regions from radiation damage

IISc has 33 papers listed on Pubpeer for image duplication

About half a dozen IISc researchers have 33 papers listed on Pubpeer for image duplication. Most of the duplication is within the same paper. With 13 papers, Akhil R. Chakravarty has the most number of problematic articles. A few researchers have already got or are about to get an erratum published. India’s premier institution Indian … Continue reading IISc has 33 papers listed on Pubpeer for image duplication

IISc team submits more evidence of superconductivity

In a new preprint posted in arXiv on June 5, the IISc team has provided evidence of signatures of critical current — the current at which the superconductor is no longer stable and becomes resistive. The critical current data is a strong indicator of superconductivity. Further evidence of possible superconductivity in gold-silver nanostructures has been … Continue reading IISc team submits more evidence of superconductivity

IISc team provides video evidence of superconductivity at room temperature

IISc researchers have posted a video evidence of diamagnetism causing magnetic levitation at ambient temperature and pressure. In the video, the nanoparticles made of gold-silver mixture seen inside a test tube can be seen getting repelled when brought close to a permanent magnet. On May 24, three days after posting a revised article in arXiv, … Continue reading IISc team provides video evidence of superconductivity at room temperature

Finally, IISc team confirms breakthrough in superconductivity at room temperature

The revised article posted in arXiv on May 21 by IISc researchers led by Prof. Anshu Pandey strengthens the claim of achieving superconductivity at ambient temperature and pressure. About the identical noise in measurements made under different conditions, the researchers say it suggests a possible physical origin related to the sample as opposed to instrument … Continue reading Finally, IISc team confirms breakthrough in superconductivity at room temperature

Science news on The Hindu website has high readership

Between January 2017 and January 2019, the Science section (excluding health, environment and technology) on The Hindu website got on average 5 lakh readers per month. And even on certain days when important news were breaking out, science articles were highly read and ranked among the top ten most read articles. On Sunday May 19, … Continue reading Science news on The Hindu website has high readership

Now, IISc team directly delivers protein into cells

By substituting a hydrogen atom of the protein with an iodine atom, IISc researchers have been successful in directly delivering proteins into mammalian cells. As a result, there was nearly six-fold increase in green fluorescent protein uptake by the cells. Supplementing the cellular protein becomes important during diseased conditions. In a breakthrough which might have huge … Continue reading Now, IISc team directly delivers protein into cells

Podcast: New approaches to kill TB bacteria

  Amit Singh from IISc explains how a protein (WhiB4) that condenses the DNA of TB-causing bacteria in response to oxidative stress was identified. The team found that artificially elevating the levels of WhiB4 protein led to prolonged compaction of DNA leading to bacterial death. Drugs or inhibitors that can either keep the WhiB4 protein level … Continue reading Podcast: New approaches to kill TB bacteria
