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.

From bits to boluses: How do termites build strong mounds?

Termites are renowned architects whose mounds have inspired many building designs around the world. But did you know how termites build their mud castles? A new study has tried to understand how termites use boluses -- a combination of mud and saliva acting as bricks -- to build their mounds. The study also throws light on the properties of materials the termites prefer to use to build mounds and discusses reasons behind the same. This study, the researchers claim, is a first towards understand the unique procedure followed by nature’s best architects in building some of the finest castles. 

Scientists design antibacterial surface that can poke bacteria to death

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.
