ಪರ್ವತಾರೋಹಿಗಳ ಅಚ್ಚುಮೆಚ್ಚಿನ ಹಿಮಾಲಯದ ಹೂವುಗಳು, ಉತ್ಸಾಹಿ ಪರ್ವತಾರೋಹಿಗಳಿಂದ ಭಾರ ಹೊರುವ ಬಗ್ಗೆ ಪಾಠ ಕಲಿತಿರಬಹುದು! ಪರ್ವತಾರೋಹಿಗಳು ಎತ್ತರಕ್ಕೆ ಹೋದಾಗ, ಅಗತ್ಯವಾದ ವಸ್ತುಗಳನ್ನು ಮಾತ್ರ ಒಯ್ಯುತ್ತಾರೆ, ಮತ್ತು ಅಗತ್ಯವಿಲ್ಲದ, ಹೆಚ್ಚುವರಿ ಸಾಮಾನುಗಳನ್ನು ತೆಗೆದುಕೊಂಡು ಹೋಗುವುದಿಲ್ಲ.
Child mortality is a leading cause of concern in many developing countries. Lack of necessary healthcare facilities has resulted in children's death due to infectious diseases such as pneumonia, diarrhoea and other complications related to preterm birth. However, most of these diseases are avoidable with inexpensive interventions like appropriate nutrition, breastfeeding and vaccination. A recent study, led by researchers from the Johns Hopkins Bloomberg School of Public Health, USA, and involving researchers from the UK, Switzerland, Canada and India, has provided some insights into how well India has fared in reducing child mortality. The study provides estimates of child mortality at a national, regional and state level in India and is published in the journal The Lancet Global Health.
The human gastrointestinal tract is inhabited by myriad microbes, which collectively form the gut microbiome. The interaction between the members of this internal 'ecosystem' can help us understand their organisation, growth, and how they react to what we eat. In summary, this tiny ecosystem in our gut determines our health. In a recent study, published in the journal Science, an international collaboration of researchers has investigated if these microbes hold a clue to the health of malnourished children.
“ಬಯೋಲೂಮಿನಿಸೆನ್ಸ್” ಅಥವಾ ಜೈವಿಕ ಬೆಳಕು ಎನ್ನುವುದು ಒಂದು ಜೀವಿಯ ಬೆಳಕು ಉತ್ಪಾದಿಸುವ ಸಾಮರ್ಥ್ಯ. ಉದಾಹರಣೆಗೆ, ಫೈರ್ ಫ್ಲೈ ಅಥವಾ ಮಿಣುಕುಹುಳ, ಬಯೋಲೂಮಿನಿಸೆನ್ಸ್ ಅನ್ನು ಸಂಯೋಗದ ಕರೆಯಾಗಿ ಬಳಸುತ್ತದೆ ಮತ್ತು ಹೆಣ್ಣು ಹುಳಗಳನ್ನು ಅದರ ಹೊಳಪಿನಿಂದ ಆಕರ್ಷಿಸುತ್ತದೆ.
If you are a fan of the movie Jurassic Park, you would have noticed the feathery-leaved massive plants, commonly called ferns. Also known as pteridophytes, they once dominated the flora of the Earth.
Study finds how pet dogs, shelter dogs and free-ranging dogs react to human gaze.
The blackbuck is an antelope species native to the Indian subcontinent. Although the term 'antelope' is loosely used to refer to many ruminating ungulates, the blackbuck is the only animal that belongs to the genus named Antilope. True antelopes belong to one of the four genera—Gazella, Nanger, Eudorcas and Antilope. Scientists are still debating the evolutionary relationships between these members. In a recent study, researchers at the Indian Institute of Science, Bengaluru, have traced the evolutionary relationships of the blackbuck (Antilope cervicapra) using phylogenetics. The study was published in the journal Molecular Phylogenetics and Evolution.
One of the annoying side effects of being absorbed in a gripping novel is that the cup of tea on the table becomes cold! Unfortunately, the tea would not heat itself by absorbing the heat around it, just as pieces of a broken egg would not put themselves together or milk mixed in coffee would not separate by itself. Such things are irreversible, and define a fixed direction of time—that from the past towards the future. This apparent progression of time is called the ‘arrow of time’. In a recent study, Prof Mahendra Verma of the Indian Institute of Technology Kanpur, suggests a way, different from any previous ones, to determine the direction in which time is progressing. He uses the concept of energy cascade to define the arrow of time.
