Manipulation of particles whose sizes are a billionth of a metre poses a huge challenge and is a vast area of research. Manipulation of objects on this scale has important application from medicines to quantum technologies. Scientists from the Indian Institute of Science, Bangalore have devised a new approach to trap and maneuver nanoscale objects. 

Wonder material graphene to make way into next gen electronic devices

Graphene is a form of carbon, just like diamond and graphite. It is made of a honeycomb shaped sheet of single layer of carbon atoms. Researchers from the Indian Institute of Science and University of Alabama have studied this material for its property of conducting electricity. Their study indicates that electrons can flow easily on the edges of graphene making it a very good conductor of electricity. 

Reduction in Amazon’s discharge into the ocean may cause floods, severe drought

The Amazon river is the largest river system in the world, discharging huge volumes of fresh water into the ocean. Scientists from the Center for Atmospheric and Oceanic sciences have explored what would be the effect of the reduction in the Amazon river’s runoff into the ocean. The scientists demonstrate the wide ranging climatic changes that can occur if the river discharges lesser water into the Atlantic ocean.

New study in mobility may prove helpful in understanding metastasis of tumour cells

Scientists from the Indian Institute of Science Bangalore devise a computational model to study how cooperation evolves in natural systems - from cells to large mammals. The study finds mobility, which was largely ignored before, plays a key role in the evolution of cooperation. Understanding mobility of cells in a medium could help us understand better the spread of cancer.

Measuring the size of a very short-lived particle

With the advances in technology our knowledge of subatomic particles and how they behave has improved considerably. But much is yet to be discovered in the subnuclear realm. Scientists from the Indian Institute of Science Bangalore, Horia Hulubei National Institute for Physics and Nuclear Engineering, Romania, and Physical Research Laboratory, Ahmedabad have developed a theoretical framework to measure the diameter of a Pion. 

Observe surface pressure over Arabian sea to predict arrival of monsoon, suggests a new study

Everyone Indian eagerly waits for the arrival of the monsoon rains. Some to just get relief from the sweltering heat while others, like farmers are dependent on the monsoon for their crops. Even though the arrival of the monsoon in Kerala is predicted accurately every year, the monsoon predictions for the other parts of the country have not been dependable. Now, scientists from the Indian Institute of Science, Bangalore have devised a new mechanism to predict the arrival of the monsoon in central India up to one month in advance.

Scientists discover a new species of paddle pod plant in Coastal Karnataka

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.

INAE announces the Young Engineer Awards for 2017

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.
