Monsoon and dehydration: Are you drinking enough water?

Dehydration is a common complaint during hot and humid weather. This is because humidity can make you feel hotter. That’s why a 320C can feel like 380C if the humidity level is as high as 65%!

Importance of hydration –

- Our body is made up of 70% water which is concentrated in all our cells. Dehydration strips the cells of water and vital minerals and hence a person feels tired, lethargic, and dizzy. Dehydration during monsoon can happen to anyone of any age. Therefore, it is very important to drink an ample amount of mineral water to replenish the body’s mineral balance and maintain a healthy temperature.

- During monsoon, people prefer multiple cups of hot beverages like coffee or tea over plain water and hence they do not realize how little water they have consumed. You may not even realize you are dehydrated until you start feeling giddy or have muscle cramps. Even a 2% decrease in the body’s water weight can lead to problems like forgetfulness, confusion, and visual disturbance1. On an average, an adult needs 2-3 liters of water daily to stay well hydrated”

Party Pairs

Atoms in a gas can seem like partiers at a nanoscopic rave, with particles zipping around, pairing up, and flying off again in a seemingly random fashion. And yet physicists have come up with formulas that predict this behavior, even when the atoms are extremely close together and can tug and pull on each other in complicated ways. The environment within the nucleus of a single atom seems similar, with protons and neutrons also dancing about. But because the nucleus is such a compact space, scientists have struggled to pin down the behavior of these particles, known as nucleons, in an atom’s nucleus. Models that describe the interactions of nucleons that are far apart broken down when the particles pair up and interact at close range. Now an MIT-led team has simulated the behavior of protons and neutrons in several types of atomic nuclei, using some of the most powerful supercomputers in the world. The team explored a wide range of nuclear interaction models and found, surprising...

Super-Resolution Imaging

Researchers at Helmholtz Zentrum München and the Technical University of Munich (TUM) have developed the world’s smallest ultrasound detector. It is based on miniaturized photonic circuits on top of a silicon chip. With a size 100 times smaller than an average human hair, the new detector can visualize features that are much smaller than previously possible, leading to what is known as super-resolution imaging. Since the development of medical ultrasound imaging in the 1950s, the core detection technology of ultrasound waves has primarily focused on using piezoelectric detectors, which convert the pressure from ultrasound waves into electric voltage. The imaging resolution achieved with ultrasound depends on the size of the piezoelectric detector employed. Reducing this size leads to higher resolution and can offer smaller, densely packed one or two-dimensional ultrasound arrays with improved ability to discriminate features in the imaged tissue or material. However, further reducing t...

Time-Stretch Infrared Spectroscopy

Spectroscopy is an important tool of observation in many areas of science and industry. Infrared spectroscopy is especially important in the world of chemistry where it is used to analyze and identify different molecules. The current state-of-the-art method can make approximately 1 million observations per second. University of Tokyo researchers have greatly surpassed this figure with a new method about 100 times faster. From climate science to safety systems, manufacture to quality control of foodstuffs, infrared spectroscopy is used in so many academic and industrial fields that it’s a ubiquitous, albeit invisible, part of everyday life. In essence, infrared spectroscopy is a way to identify what molecules are present in a sample of a substance with a high degree of accuracy. The basic idea has been around for decades and has undergone improvements along the way. In general, infrared spectroscopy works by measuring infrared light transmitted or reflected from molecules in a sa...
