क्षयरोग के जीवाणु प्रसुप्त अवस्था में अपने बाह्य आवरण में होने वाले परिवर्तन के कारण प्रतिजैविक (एंटीबायोटिक्स) से बच कर लंबे समय तक जीवित रह सकते हैं।
மீநுண் தொழில்நுட்பம் எனப்படும் “நானோ தொழில்நுட்பம்” இன்று அறிவியலில் மிகப்பெரும் மாற்றத்தினை உண்டாக்கி வருகின்றது. மூலக்கூறு அளவிலும் கூட பருப்பொருட்களை கையாளும் தொழில்நுட்பமே மீநுண் தொழில்நுட்பம். மீநுண் துகள்கள் கரிமம் சார்ந்த மற்றும் சாராதவை என இரு வகைகளில் உள்ளன, இவைகள் மிக நுண்ணிய அளவினைக் கொண்டதாகும்.
Bioluminescence is the ability of an organism to produce light. How does each animal use bioluminescence differently?
During the years 2018-2019, India witnessed a few ‘Kisan Long Marches’, where thousands of farmers took to the streets. They marched against state and central governments to alleviate their suffering. Their demands included loan waivers, proper land ownership rights, access to insurance and other welfare schemes, and obtaining a justified price for their crops. The Indian farming community is facing a crisis and farmer suicides are increasing by the day. Does the country’s social and caste structure add to these woes of the farming community? A recent study by researchers has found some insights. The study, published in the journal PLOS One, explored if caste of the farmers played a role in them having access to agriculture-related information.
In an announcement made yesterday, the Council of Scientific and Industrial Research (CSIR) has published a list of the recipients of the Shanti Swarup Bhatnagar Prize for 2019. The list includes twelve eminent scientists from various research institutions across the country, with only one woman scientist from the Indian Statistical Institute, Kolkata.
During the fag end of 2015, Chennai experienced severe floods resulting in the death of about 500 people and economic losses of about INR 50,000 crores. The flooding stranded the city and was termed a 'man-made disaster' resulting from irresponsible water management and rapid urbanisation. The northeast monsoon of the year left most parts of South India marooned, exposing how vulnerable our cities are to such catastrophes. That's when the Office of the Principal Scientific Advisor took a major initiative to develop a real-time, integrated, urban flood forecasting system that was non-existent in our country. Soon after, a team of scientists from various institutes across the country, swung into action to develop the first-ever expert system in India to forecast floods. In a recent study, published in the journal Current Science, the researchers shed light on the development of the automated flood forecasting expert system.
ಅಂಜೂರ ಮರದ ವಿತರಣೆಯು ಕಣಜಗಳ ಪ್ರಸರಣ ವಿಕಾಸದ ಮೇಲೆ ಹೇಗೆ ಪ್ರಭಾವ ಬೀರುತ್ತದೆ ಎಂಬುದನ್ನು ಸಂಶೋಧಕರು ಅಧ್ಯಯನ ಮಾಡಿದ್ದಾರೆ
The city of Delhi has been consistently ranked as one of the world's most polluted cities. As the monsoon ends, haze sets in, with Deepawali around the corner, bringing the entire city to a standstill with low visibility. Besides vehicular emissions, smoke from diesel generators and construction dust, a significant contributor to this problem is the practice of crop residue burning by farmers in Punjab and Haryana. A recent study, published in the journal Nature Sustainability, suggests that groundwater conservation policies, adopted by Punjab and Haryana, have changed the patterns of rice production. These policies, the researchers argue, have led to the concentration of crop residue burning into a narrower period, later in the season.
The nucleus of the cell holds our genetic material and is a vital part of our cell. Apart from what they carry, how they look also plays a crucial role in diagnosing many diseases. In a recent study, researchers at the Indian Institute of Science (IISc), Bengaluru, have developed a mechanical model to quantify the shape of the nucleus and predict the biochemistry within a cell. They have used this model to show how Hepatitis C virus changes the nuclear mechanics of cells affected by it. This study is published in the Biophysical Journal.

The flowers in the Himalaya, a favourite among mountaineers, may have borrowed a lesson or two from the adrenaline-high visitors. As they climb higher, mountaineers carry only essential things, shedding any extra baggage. Likewise, the flowers here shrink in their size and hold less nectar to suit their tiny pollinators, finds a recent study on Rhododendrons, a type of woody flowering plants. The study was conducted by researchers at the Ashoka Trust for Research in Ecology and Environment, Bengaluru and is published in the journal Alpine Botany.
