Flooding in urban areas in a major threat to life and property. While there is a focus on immediate relief to the victims after the flood, long term effects of the flood need to be explored in more depth. In a recent study, an international team of scientists explores the aftermath of the floods in Chennai in 2015 with regards to the potability of groundwater. The team shows that even five months after the floods the groundwater is still unsafe for human consumption due to heavy metal and microbial contamination. 

Information and communication technologies (ICT) has been revolutionized with the arrival of smart devices and applications. Whether it is taking a video call, working from home, ordering food or arranging transportation, a smart device like our smart phones and computers, along with smart applications like Uber and Swiggy has made many of our daily chores much more efficient and simple.

Eyes are one of the most complex organs found in animals. Through evolution the eyes of animals have evolved to suit some needs better than others. Some animals can see the world in 3D, while some others can see in the dark. Animals living in places where the light doesn’t reach like caves, can’t use their eye and hence have primitive eyes. Researchers from Institute for Stem Cell Biology and Regenerative Medicine, study the pit eye seen in the flatworm Planaria to understand how the organism senses the environment around it.

Gold is arguably the most enigmatic element on Earth. Its value as a form of currency, an industrial metal, and its cultural significance have made it the most sought-after metal all over the world. It wouldn’t be unfair to say that gold is the stuff of legend. A tad dramatic perhaps? But then the story of gold is dramatic! Its presence on Earth tells of stellar cataclysms and extraterrestrial travel.

The rhythmic contraction and relaxation of muscles of the food-pipe or the oesophagus, called peristalsis, pushes the food to the stomach. Researchers from Indian Institute of Technology, Varanasi have developed a mathematical model of the human oesophagus that could explain the pressure variation in the oesophagus. A detailed understanding of how food is pushed to the stomach can help develop an artificial food-pipe or prosthetic oesophagus, a lifesaving treatment for oesophageal cancer and certain oesophageal disorders.

Scientists from the Indian Institute of Science, Bangalore have described a new species of plant in Coastal Karnataka. Here the team describes the morphological features that helped them identify the plants as a separate species. They find that Reissantia sessiliflora is endemic to the region and highlight the threats faced by the plant along with the actions the public can take for its conservation.

The Indian National Academy of Engineering, a consortium of distinguished engineers in the country, has announced the winners of the annual Young Engineer Award 2017. With 3 awards, IISc grabbed the highest number of awards this year followed by ISRO and six IITs winning one each. The award is given as a recognition to engineering and scientific contributions in the country, with individuals selected from government, academia and industry. 

Cancer is a difficult disease, both for patients and doctors. One of the many side effects of cancer therapies is secondary infections that are caused by a weakened immune system. Current strategies for treating bacterial infections in cancer patients have many drawbacks. Addressing these issues scientists from the Indian Institute of Technology, Delhi show that administering antimicrobial medicines with gold nanoparticles increases their efficacy by upto 40%.

We live in an era of medical advancements where sequencing of the human genome and its subsequent applications in personalised medicine, offer to completely revolutionise the diagnosis, treatment and even prevention of various diseases. Personalised or precision medicine is an approach that strives to move away from the ‘one-size-fits-all’ philosophy of Western medicine. It tries to cater to an individual’s disease condition, genetic predispositions as well as local environmental factors. Surprisingly, the concept of personalised medicine isn’t a brand new one.

Transistors are the backbone of the zillion electronic devices that we use today. While development of these semiconductor devices dates back to four decades, it's applications are ever increasing. Internet of Things is the new application that is transforming the development of transistors. In view of this, scientists at IIT Bombay and SCL ISRO have developed a new kind of Bipolar Junction Transistor that is completely indigenous. The researchers believe a home made technology can see its application in strategic sectors like space and defence.
