Sodium is the predominant electrolyte in our body. It plays many important functions, such as maintaining proper fluid balance in the body, in assisting nerves conduction and in regulating blood pressure. But drinking too much water can disrupt its functions and has adverse effect in our health.
Engineers at Cornell University have developed a programming language that allows tiny robots to behave autonomously like real insects. For the study, the team used 80-milligram flying RoboBee developed by Harvard Microrobotics Laboratory and made use of neuromorphic computer chips – which can process spikes of electrical current that fire in complex combinations, similar to how neurons fire inside a brain – to power it.
Magic is science we simply don't understand yet. Firebending truly is no exception. This independent scientist demonstrates a fascinating characteristic of fire - its ability to be manipulated and controlled using electrostatic charges.
Engineers at MIT have made a breakthrough in creating bioluminescent plants that glow in the dark. By injecting specialized nanoparticles into the leaves of a watercress plant, the team induced the plant to give off dim light for nearly four hours.
In this Numberphile video, Tadashi Tokeida, Japanese mathematician, explains the physics behind why paper balloon can be inflated just by tossing it around. The balloon he used in the video is kamifusen – a traditional Japanese paper balloon.
Researchers have invented a groundbreaking method to detect tiny cancerous tumors and track their spread. The method uses infrared light-emitting nanoparticles that can detect the presence of micrometastases months before they grow big enough to be able to detect by traditional imaging techniques.
Which is smarter: a cat or a dog? This question has stumped experts throughout the ages and has been impossible to answer due to complex nature of intelligence of both the animals. Now, researchers at Vanderbilt University have managed to come up with an answer by calculating the number of neurons in their cerebral cortex. And it turns out – dogs are smarter.
Researchers have for the first time recorded mysterious ‘hum’ generated by Earth’s movement - using seismic instruments on the bottom of the ocean. The first attempt to detect this low-frequency vibrational signal was made in 1959, but it wasn’t until 1998 that researchers were able to prove it exists.
Physicists have proven the existence of new form of matter called excitonium, almost 50 years after it was first theorized. Upon studying non-doped crystals of the transition metal dichalcogenide titanium diselenide (1T-TiSe2), the researchers were able to observe the material and its precursor soft plasmon phase called the "smoking gun" that proves the existence of this rare, exotic material.
