Researchers at IIT Bombay discover the role of environmental resources, genes and mating in species in the development of new species in the same area, challenging the traditional view that new species can develop only in distinct geographies.

While open defecation has well known health risks, toilets with sewage pits come with their own drawbacks. One of them is the contamination of ground water due to sewage leachate -- the water that seeps into the soil from the pit and has extremely toxic levels of nitrates, ammonium and organic carbon. These toxins are known to contaminate ground water making it unfit for drinking. Now scientists have designed a twin-pit toilet system that reduces the levels of nitrates, ammonium and organic carbon in the sewage water before it is being absorbed by the ground. This treated water, the researchers say, have low levels of toxins, making it safe and saving water bodies from contamination due to sewage.

In a city like Bangalore, public transport system has a huge responsibility of transporting millions everyday and is a necessity to decongest the cities roads and help the city take a step towards sustainable living and greener environment. BMTC, the city's public transport cooperation has introduced many fleets of buses catering to different areas and targeting different types of customers. A new study now evaluates the sustainability of BMTC's fleet of Volvo buses and suggests ways that could help the cooperation maximise its profit and run its services efficiently.

India is no stranger to air pollution, with the capital, New Delhi, being identified as one of the most polluted cities in the world, several times. The harmful effects of this deteriorating air quality can be seen in the increasing number of patients with respiratory disorders. Now, a team of scientists have designed a novel gas sensor using MEMS technology that is compact, highly sensitive, consumes very little power and accurately detects gaseous pollutants like CO, CO2, NO2 & SO2.

The race to space is heating up with the addition of private players around the world. With increasing competition to make space explorations affordable, there is a whole ecosystem of small and big companies trying to eye the possible revenues. One among them is the award winning start-up from Bangalore, incubated at IISc, called Bellatrix Aerospace. In a recent conversation with Research Matters, the company reveals its plans for the future and talks about its innovative solutions that aim to make space explorations cheaper than ever.

A new study at IISc looks to uncover the secret behind the development of drug resistance in TB causing bacteria by testing the efficacy of various commonly available antibiotics. The researchers have found that a combination of commonly available antibiotics along with Augmentin, fights the development of resistance among TB bacteria. This study might throw light on developing new class of drugs that can help contain the spread of deadly tuberculosis, claim the researchers.

The Education and Research Network or better known as the ERNET project was initiated in 1986 by the central government with the aim of connecting the different academic institutions across the country and introducing research in networking in the country. By 1992, ERNET had become the country’s first internet service provider. In January 2016 it was mutually decided to end the agreement between ERNET and IISc, thus bringing to an end a three-decade long effort in data networking.

Foodborne diseases, caused by Salmonella, are responsible for 1 in 10 illnesses globally. Treating Salmonella infections using traditional antibiotics is turning to be a challenge because of the development of drug resistant strains. Now, a new study at IISc has developed nanotechnology based nanocarries using silica that can deliver very small dosage of antibiotics to the affected cells, thus hitting the right target. Using laboratory experiments, the researchers found that these nanocarries performed much better than conventional antibiotics in all stages of the infection. The design of these nanocarries are generic, and can be used for delivering different antibiotics, they claim.

Malaria, a deadly mosquito borne disease, kills about half a million people around the world, every year. Developing countries face a challenge in accurately diagnosing malaria in early stages due to the need of sophisticated diagnostic devices and skill. A new study at IISc has developed a technique to test for malaria with very small quantities of blood samples using laser light. By holding a single RBC using a pair of 'optical tweezers', this technique can detect malarial parasites in the RBCs even at an early stage, say the researchers. The researchers claim this technique can help save many lives if commercialised on a larger scale.

Securing communication channels has been a long standing challenge for humans ever since early civilisations. Thanks to advances in computation, many so called 'secure' algorithms have been broken and the risk of information being in the wrong hands is at an all time high. A new study by researchers from IISc and NIT-Karnantaka has now developed an improvised version of a cryptographic algorithm based on quantum physics. This algorithm, the researchers claim, works efficiently and faster than their previous versions and allows higher data rate. They also also developing a new breed of communication devices running the improvised algorithms. These devices, the researchers claim, can be integrated into existing infrastructure, making them all the more secure.

Our lifestyles influence our behaviour in a big way -- or so we think. But did you know our activities have a major influence on other creatures living around us? In an interesting study, scientists have uncovered how urbanization has influenced the courtship behaviour among south Indian rock agamas and their escape strategies. The study found that these agamas use change of colour of their body as communication signal during courtship and aggression and human activities and urbanization have a great influence in the everyday lives of these lizards.
