In you childhood days, you might have killed an ant by squeezing or poking it. Or may be smashed a pest like cockroach. But how about killing bacteria by poking them? What if that means a bacteria-free world? A new study by scientists has tried to exactly that using nanoscale surface undulations on titanium surface to kill bacteria by rupturing their cells. This innovation, the scientists say, serves as a great alternative to getting rid of bacteria instead of using antibacterial drugs.

Bengaluru is today famous for the number of technology companies that have sprung up, be it domestic or multinational. A new addition to this list are the home-grown technology start-ups who have transformed Bengaluru into a hub of technology start-ups. But what factors led to this transformation of a city that was once a ‘pensioner’s paradise’ into one that is bustling with the energy of the youth? A new study has now tried to identify those factors and analyse how each of them helped Bengaluru transform into what it is today. Read on to learn about this exciting journey.
Have you ever wondered how animals communicate with each other? While some might use sound by howling, chirping or roaring, others, like the resplendent superb fan throated lizards have evolved a unique form of communication using colors. In a new study, researchers have understood the complex system these lizards use to signal to each other using their colorful dewlaps. Using colors like orange, blue and black, these lizards signal differently to males and females of their own, say the researchers.
As cancer, a deadly disease, evolves, our fight against it does so too. Today, there are multiple therapies and drugs available that fight different types of cancer. Now, researchers have added a new drug called Disarib to this list that acts against a particular protein called BCL2. By killing cells that overproduce this protein, the researchers claim that Disarib can act effectively against most types of cancers. A first kind of its drug made completely in India, Disarib heralds a new breakthrough in Indian pharmaceutical research.
Though our fight against tuberculosis has a long history, we have not been able to wipe off this bacterial infection from the face of the planet. Even to this day, there are numerous studies all over the world that are trying to find the ‘best’ drug against this killer disease. In a new approach to fight tuberculosis, a recent study has now shone some light on how our body fights Mycobacterium, the causative bacteria of TB. Understanding this mechanism, the researchers say, could open up new vaccines and drugs against TB and help us win the seemingly never ending battle.
Human hair has become all the more valuable, according to a spate of recent studies finding diverse applications of keratin, a protein found in our hair, in tissue engineering and stem cell research. Gone are the days when discarded hair was used for wigs, making fertilizers or in construction materials. Now, researchers have demonstrated the use of keratin derived from human hair as a scaffold to grow cells in bioengineering. The easy availability o f human hair and keratin makes research in tissue engineering very inexpensive, claim the researchers.
Micro electro-mechanical Systems (MEMS), the technology of microscopic devices with moving parts, are finding new range of applications in the recent past due to the trend of ‘miniaturization’. They are increasingly being applied to an array of sensor technologies, including gas sensors. However, for MEMS based gas sensors to detect small traces of gases, they need to operate at higher temperatures. Now, researchers have designed a microheater made of molybdenum, which can successful provide the required range of temperature for the sensor to operate.
Technology has revolutionized almost every aspect of our lives - from healthcare to doing business. The field of meteorology is not far behind. In a recent study, scientists have leveraged the computing power of a new series of processors from Intel, to improve existing climate models and simulations. The new models, the researchers claim, have better accuracy and increased speeds and also free up meteorologists from the hassles of computer science.
Relationships between various organisms stem to achieve an ultimate objective - survival. In mutualistic relationships, all involved in the relationship help each other survive, whereas in parasitic relationships, only one of those have an upper hand. But in spite of this chaos, how does nature maintain a balance? In a new study, scientists have studied examples of such relationships between termites and fungi - both mutualistic and parasitic - and have uncovered some interesting strategies adopted by these fungi to survive and thrive.
The public transport system of Bengaluru is plagued by delays and inefficiencies that have resulted in huge losses to BMTC, the operator, and lack of quality services to the common people. Now, scientists from the Indian Institute of Science have proposed a new model of transport that aims to increase bus efficiency, reduce or eliminate delays and save money for both the transport corporation and its users - the people. The new model, researchers claim, could be a win-win situation for both and could revive the appeal of public transportation.
