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. 

Our gastrointestinal tract is teeming with a variety of microorganisms, which we obtain from our mothers during childbirth and also through breastmilk. How do our unicellular gut tenants participate in our lives by being an integral part of the gut-brain axis? 

Antimicrobials, a class of drugs used in humans and animals to treat diseases caused by bacteria, fungi, and parasites serve as a proxy for good hygiene and make up for the poor husbandry practices in animal farms in low and middle-income countries around the world. However, this dereliction comes with a considerable cost wherein, the overuse of these drugs has led to these microbes developing resistance against the very same drugs used to kill them.  Antimicrobial resistance (AMR) in humans is linked to several animals, especially those that are raised for food. Despite this knowledge, it has received little attention in the world of animal science. A new study, published in the journal Science, has mapped the global trends of antimicrobial resistance in farm animals, with particular focus on developing countries, including India. 

பல்லுயிர் ஓம்புதலிலும் இயற்கையினை கூர்நோக்கி உணருவதிலும் இந்தியர்கள் குறிப்பாக தமிழர்கள் ஈராயிரம் ஆண்டுகளாகவே சிறந்து விளங்கியிருந்துள்ளனர் என்பதற்கு பல சங்க இலக்கியங்கள் சான்றாக நிற்கின்றன. நிலப்பரப்புகளை ஐந்து வகைகளாக பிரித்த நம் இலக்கியங்கள் அவற்றின் உட்பிரிவுகளையும் அவ்வப்போது உற்று நோக்கியிருந்துள்ளன.

The leading cause of death in the world is not wars or famines but cardiovascular diseases, and worse still, we haven't fully understood what causes these ailments. Researchers believe it to be a mix of genetic factors, lifestyle changes, diet and environmental factors like air pollution, noise and our neighbourhood. In recent years, cases of high blood pressure and hypertension, which directly contribute to heart diseases, have increased, and those living in low and middle-income countries are the most vulnerable.  A recent study, published in the journal Epidemiology, aims to examine the associations between long-term exposure to ambient particulate air pollution, and prevalence of hypertension in adults from peri-urban India.

ಶಾಲೆಯಲ್ಲಿ ಕಲಿಯಬೇಕಾದರೆ ಗಣಿತದ ತರಗತಿ ನೆನಪಿದೆಯೇ? ಗಣಿತ ನಮ್ಮಲ್ಲಿ ಬಹುಪಾಲು ಜನರಿಗೆ ಕಬ್ಬಿಣದ ಕಡಲೆಯಾಗಿತ್ತಲ್ಲವೇ? ಅರ್ಧಕ್ಕಿಂತ ಸೂತ್ರಗಳನ್ನು ಸುಮ್ಮನೆ ಬಾಯಿಪಾಠ ಮಾಡಿ ಪರಿಕ್ಷೆಯಲ್ಲಿ ಬರೆಯುತ್ತಿದ್ದುದು ನೆನಪಿದೆಯೇ? ಇಂತಹ ತಲೆನೋವಿನ ಸೂತ್ರಗಳಲ್ಲಿ ಗೋಳದ ಮೇಲ್ಮೈ ವಿಸ್ತೀರ್ಣದ ಸೂತ್ರವೂ ಸಹ ನಾವು ಬಾಯಿಪಾಠ ಮಾಡಿ ಬರೆದ ಸೂತ್ರಗಳಲ್ಲಿ ಒಂದು.

Carbaryl is one of the commonly used pesticides for agricultural as well as non-agricultural use. But like any other insecticide, higher concentrations of Carbaryl in the soil can have adverse effects on humans and other organisms. The need to completely remove it from the environment or break it down into less harmful substances is of primary importance. Researchers from the Indian Institute of Technology Bombay (IIT Bombay), and Institute of Genomics and Integrative Biology (CSIR-IGIB), Delhi, have achieved a significant breakthrough in identifying bacteria which can clean up this pesticide from the environment and understanding exactly how the breakdown occurs.
