Bioelectronic nose sniffs out bacteria in water
Currently, when scientists want to know if bacteria are present in water, they have two main choices. They can take a sample to the lab, where they’ll try growing the suspected bacteria in it, and then count the number of resulting colonies to determine the concentration.
New sensor detects water contamination in real time
Currently, if you want to check water supplies for the presence of toxic bacteria, you have to take a water sample and then culture it in a lab over several days. In the meantime, it’s impossible to say if the water source is safe to use. A group of students from the Technical University of Denmark, however, have created a sensor that they say can detect bacteria in water instantly, on the spot.
This involves running a liquid sample continuously through a microfluidic channel. Within that channel is a series of electrodes, to which a multi-voltage electrical signal is applied. As bacteria and other particles flow across those electrodes, they cause a change in impedance, which is detected by the sensor. Read more
Extracting Water from the Air
Without water, humans cannot live. Since time began, we have lived by the water and vast tracts of waterless land have been abandoned as too difficult to inhabit. A new machine which extracts water from air could change that …
How much should we drink?
To answer the most important question, there is no correct or magic formula to follow to ensure you are properly hydrated each day. However, there are guidelines that you can follow to ensure that you get as close as possible to the perfect daily water intake. The most important aspects to take into consideration are your body weight, environmental conditions, diet and your level of fitness. If you take weight as the one of the main factors, then a person who weighs 65 kilograms and does an hour and a half of exercise will need less water than someone of 110kilograms doing only thirty minutes of exercise.
