The human body harbours around 100 trillion microbes (bacteria, virus and others). While some harm us, others help us in different ways. A new study has now analysed the microbes present in our blood and has found that from an evolutionary perspective, they are related to each other, and strangely, even related to humans. This discovery has implications in drug discovery and designing therapies against harmful microbial infections.

Since ancient times, India has had a rich culture of metallurgy as evidenced in the archeological finds from Indian Iron age. The vessels and ornaments found from this period show skilled metallurgy and craftsmanship in smelting metal. Now, Prof. Sharada Srinivasan, a Professor at the National Institute of Advanced Studies, has been studying these ancient traditions and skills in working with metal.

Uric acid is a compound made of carbon, nitrogen and oxygen, and is one of the components in urine. High amounts of uric acid in the blood could lead to many debilitating medical conditions such as diabetes and gout. However, detecting the compound in living cells without damaging the cells can be quite a challenge. Now, scientists from Visva- Bharati Santiniketan, West Bengal, Indian Institute of Engineering, Science and Technology, Howrah and University of Calcutta, Kolkata have devised a novel way of detecting uric acid without disrupting the cell.

Pursuing research is one of the aspirations of many young minds stepping out of their college. Unfortunately, for many, this aspiration remains largely a dream as costs of higher education are increasing day by day. But what makes higher education so expensive? In such scenarios, should students bear the cost of research? If not, then who should bear them and why? How can different beneficiaries of university research work to help students come out of the burden of education costs and serve society at large? In a conversation with the Research Matters team, the winner of 2011 Nobel Prize in Physics, and the current Vice Chancellor of the Australian National University, Prof. Brian Schmidt, shares his views on the topic of research funding.

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.

Isoprene is a naturally produced organic compound, produced by plants. It is a colourless volatile liquid produced by many plants and is the main component of natural rubber. Although the role of isoprene as a pollutant is yet to be confirmed, it has been shown that in the presence of high amounts of nitric oxides, isoprene can lead to the formation of lower atmosphere ozone, which is considered as a leading air pollutant in many countries.

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.

Escherichia coli, commonly called E. coli, is a bacteria that can be found in the gut of many warm blooded animals, including humans. Although many strains of the bacteria are harmless, a few strains of E. coli are pathogens that causes diseases like food poisoning, urinary tract infections and pneumonia. A little known fact however, is that E. coli is also responsible for infections of the eye leading to conditions like conjunctivitis and keratitis.
