Graphene, also called a “wonder material” is increasingly being used in the field of electronics due to its lightweight and electrical properties. Now, researchers at the Indian Institute of Science, Bangalore, have identified a potential drawback in graphene transistors that have metal contact leads. The metal atoms in the contacts react with graphene atoms, creating an unwanted disturbance or noise in the electronic circuit. This discovery may have major implications on using graphene for futuristic electronic applications.

The National Rural Employment Guarantee Act 2005, which was later renamed to Mahatma Gandhi National Rural Employment Guarantee Act (MNREGA) is a labour law passed to ensure employment for the rural population. The act provides 100 days of guaranteed wages to an unskilled manual labourer, helping them cope with the unemployment.
A team of scientists from Centre for Ecological Sciences (CES) at the Indian Institute of Science (IISc) have discovered a new species of plant – Reissantia (Celastraceae).
In a pathbreaking research on anencephaly, a fatal birth defect where a baby is born without a major part of the brain and the skull, researchers from IISc and BMCRI have identified a genetic mutation that is responsible behind this condition. Technically called Tripartite Motif Containing 36 (TRIM36), this gene is responsible for the development of the nerve cells in a foetus. A modification to this, the scientists say, is to be blamed for anencephaly.
Electricity has become a basic necessity today - powering our homes to running our machines, all run on electricity. This growing need for electricity has seen the rise of smart grids - a network of electric supply system that detects changes in usage of electricity in real time and helps to manage the demand-supply equation.
Saffron, the most expensive spice from the Middle East, is also well-known for its neuropsychological effects, apart from its culinary uses. Now, researchers from Savitribai Phule Pune University and University of Kansas Medical Centre have studied the potential of Safranal, a chemical present in saffron, for its anti-inflammatory and cancer fighting abilities.
Electronic waste or e-waste pose a serious challenge in their disposal. The printed circuit boards (PCBs) present in discarded electronic devices like smartphones and computers contain toxic chemicals and metals that can get into the soil or water if thrown in landfills or burnt. Now, scientists have designed a novel technique to dispose them by simply powdering them using a cryomill. This, they claim, can completely recover the polymers and metals for recycling in an eco-friendly way, ensuring zero waste.
Ever wondered what happened to all our centuries-old learning of using natural dyes on fabric like cotton, silk and wool? With synthetic dyes that are non-biodegradable, carcinogenic and pollute our waters, we are doing more harm than good to ourselves.
A new study by scientists at Translational Health Science and Technology Institute (THSTI) and Indian Institute of Chemical Technology (CSIR-IICT), has found a link between lower vitamin D levels and prevalence of hypertension in pregnant women.
Tuberculosis or TB is a disease known to mankind since our existence on Earth. In spite of that, our fight against this deadly disease still continues. A major breakthrough in this fight is the identification of Mycobacterium tuberculosis, the bacteria that causes TB, in the 19th century. World Tuberculosis Day is celebrated commemorating that significant day, when Robert Koch discovered this deadly bacteria that has now become stronger than ever, and standing tall against all odds in this fight. Will we ever succeed? Only time can tell.
