Chronic Kidney Disease in Rural Andhra Pradesh
Cases of chronic kidney disease of unknown cause were seen in Uddhanam, Andhra Pradesh and later, in Tamil Nadu and Pondicherry. Similar cases have been reported from other parts of the world. What are the kidney pathologies in such cases and what could be the cause? Recent research provides clues. A report by M Karunanithi.
Protecting brine shrimp from vibriosis: Probiotic bacteria
The brine shrimp, used for toxicity tests in labs, is an important fish feed in aquariums and aquaculture. But commercial scale breeding of brine shrimp faces risk of bacterial infections. Researchers have found a way to protect brine shrimp from bacterial infections by using probiotic bacteria. M S Shivakumar reports.
Malignant Melanomas in India
Melanoma patients in India have a pattern of mutations that is different from the pattern seen worldwide, say researchers from the Homi Bhabha National Institute. While 75% of the patients in global sample have mutations in two genes, Indians cases have only 31%. A Anuradha reports.
Nitrogen Dioxide Sensors: high sensitivity, fast response
Zinc oxide can be used as a sensor for nitrogen dioxide, a harmful gas. Researchers at PSG Institute of Advanced Studies, Coimbatore find that a nanofiber of zinc oxide sheathed by a thin layer of another metal oxide can improve the sensitivity as never before. Vishal Baloria reports.
Wild Edible Plants: Wancho tribe diet
The Wancho tribe in Patkai hills, Arunachal Pradesh do not follow their wild ways anymore and cultivate food. But they still collect wild plants as food. Researchers from NERIST, Arunachal Pradesh recently examined the nutritional qualities of four such plants. Rojjita Mishra reports.
Potato Peels and Pea Pods
Cellulases, enzymes that break down cellulose, are in high demand. But the supply is limited. Indian researchers have now come up with new sources and cheap raw materials to produce cellulases at an industrial scale. K. Yashkamal reports.
Bullet Chilli Seeds
Decades of irrigated cultivation of crops is turning agricultural lands more saline. So search is on for salt tolerant varieties. Recently, researchers from West Bengal explored the extent of salt tolerance of seeds’ germination and growth in a salt tolerant variety of chilli. Samikhya Bhuyan reports.
Converting Carbon Dioxide to Methanol
To keep carbon dioxide emissions under control, convert the green-house gas into methanol. To do this, there is a simple method developed recently by scientists at CSIR-NCL Pune and IIT Palakkad. Ajesh Zacchariah reports.
Sex Selection Technology
Mukesh Kumar Gupta from the NIT Rourkela collaborated with Korean researchers to separate cattle sperms that carry X chromosome using a monoclonal antibody against sperms that carry Y chromosome. They could get 95% female embryos in vitro.
Bay Laurel Leaves: protect aquaculture fishÂ
Fish productivity in aquaculture is affected by disease-causing microorganisms. To treat the diseases, antibiotics are used. But indiscriminate use leads to antibiotic resistance in the microorganisms. Instead of using antibiotics, we could improve the resistance of aquaculture fish to infections using immune-stimulants to activate immune responses to the infections. Recently, researchers at the Karnataka Veterinary, Animal and Fisheries Sciences… Read More ›
