India produces a large amount of agricultural products due to its fertile soil and dependable rainfall patterns. Any harm to the soil would affect the lives of millions in the country. Soil erosion due to rainfall is one such threat. In an first of its kind study an international team of scientists have designed a global map of soil erosivity to devise mechanisms to protect our soils from erosion due to rainfall.

We live in a world where day to day objects seems to be getting smaller and better. The advent of nanotechnology is a major contributing factor to this phenomenon. Defined as the “engineered construction of matter at the molecular level”, nanotechnology has applications and uses in a multitude of fields. From medicine, electronics, food, clothing, batteries and environment, nanotechnology seems to be pushing the limits of all these fields. Now, scientist have discovered yet another novel application of nanotechnology – facilitating soil microbial growth.

Plants belonging to the genus Parthenium are native to the North American tropics. These hardy plants have moved out of their native range and colonized far off countries like Australia, parts of Africa and even India. The species hysterophorus belonging to this genus has earned common names like famine weed as spreads it into farm lands, uses up the nutrients in the soil and causes devastating loss in yield of crops.

An important aspect in the life of social animals is to gather information from others in their group. Young members of the group also learn how to forage, feed, evade predators and attract mating partners from older members. Scientists from Indian Institute of Science Education and Research, Kolkata explore how Zebra fish, that live in shoals of 20 individuals in the wild, learn informations from their partners in a laboratory environment.

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. 

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.

Snakehead fishes are predatory ray-finned fishes belonging to the family Channidae. Found across Asia and Africa, snakehead fishes are important sources of food, and are widely cultivated by humans. Snakehead fishes are known survive on wet land for up to 4 days, and are considered to be a highly invasive species, with a single snakehead female capable of laying up to 150,000 eggs in just a span of two years. So far, 38 valid species of snakeheads had been recognised.

Chillies are an indispensable  part of the Indian platter and contribute heavily to our economy since India is a leading producer of chillies. A threat facing the chilli farmers is the fungal disease caused by Colletotrichum truncatum that affects the yield of the crop. In a new study, scientists have explored the mechanism behind the fungal disease, how the fungus actually attacks the plant and fruits and have also studied the genotype of the causative agents. This study, the researchers believe, can help develop mitigation plans and save farmers from an impending crop loss.

Have you ever been away from the city, away from the bustling activities and clattering? If you have, then, without all the noises of the city to distract you, you might have noticed how loud a seemingly empty field is! Birds, frogs and insects all join in on this chorus. The animals making these calls need to invest time and energy into making them, and hence are made for specific reasons, where every call counts.  Often, in the animal kingdom these vocalisations are used to attract potential mating partners.

What do sword billed humming birds, fig wasps and acacia ants have in common? It’s the phenomenon of co-evolution, where these organisms are dependent on other organisms for survival and they reciprocally affect the other’s evolution.
