At Busy Minds we strongly believe that science can be learnt in a Fun-Filled, interactive style with usage of real life examples. Keeping this in mind we have infused games, puzzles, quizzes, stories interesting anecdotes and most importantly plenty of “hands on” experience to accelerate the learning process.
spotted these cute, adorable arachnids in Amravati, Maharashtra. As kids we were fascinated by its bright red colour, we would grab them and store them in match boxes (Owe them a huge apology for the cruelty). They would appear at the onset of Monsoons and were a very common sight those days. Called as Gosavi Kida, Mruga Kids, Rain bugs.
Red Velvet Mites are diurnal, hibernate in winters, active in summers. Red Velvet Mites are an integral part of the soil and leaf litter ecosystem. Since these mites feed on other mites and small arthropods that would eat fungus and bacteria, they increase the rate at which decomposition occurs in the soil layer. Red velvet mites keep the fungus and bacteria alive by eliminating their predators. Adult velvet mites are generalists and will eat arthropods that are much larger than they are. They also will eat pupae, larvae, and eggs of other arthropods. Organisms in the larval stage will parasitize species in the group Orthoptera. These include grasshoppers, crickets, and locusts. In fact, velvet mites are used to control the population of certain locusts.
In order to reproduce, velvet mites will perform a mating dance. It is at this point that the male velvet mites lay an intricate silken web of s***m on a twig. If a female finds the web and its construction impresses her, she will find the artist and sit on the s***m. If, however, another male finds a web of another males s***m, he will destroy it and create his own, new web.

Ștefania Mărăcineanu was a Romanian physicist.
After World War I, with support from Constantin Kirițescu, Mărăcineanu obtained a fellowship that allowed her to travel to Paris to further her studies. In 1919 she took a course on radioactivity at the Sorbonne with Marie Curie.
Mărăcineanu researched the half-life of polonium and devised methods of measuring alpha decay. This work led her to believe that radioactive isotopes could be formed from atoms as a result of exposure to polonium's alpha rays; an observation which would lead to the Joliot-Curies' 1935 Nobel Prize.
Mărăcineanu publicly claimed that she discovered artificial radioactivity during her years of research in Paris, as evidenced by her doctoral dissertation, presented more than 10 years earlier. "Mărăcineanu wrote to Lise Meitner in 1936, expressing her disappointment that Irene Joliot Curie, without her knowledge, used much of her work, especially that related to artificial radioactivity, in her work.
Mărăcineanu also investigated the possibility of sunlight inducing radioactivity; work which was contested by other researchers. Nevertheless, a 1927 article from the Geraldton Guardian remarked: "Cheaper radium is foreshadowed in a communication to the French Academy of Sciences by a girl scientist, Mlle. Maricaneanu[sic], who [...] by means of lengthy laboratory experiments, has been able to demonstrate that lead exposed for a long time to the sun recovers its radioactive properties. The mechanism of this transformationi s a complete mystery but it is regarded of such tremendous importance to medical science that further close research work is to be pursued.

An aurora[a] (plural: auroras or aurorae, also commonly known as the polar lights, is a natural light display in Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic). Auroras display dynamic patterns of brilliant lights that appear as curtains, rays, spirals, or dynamic flickers covering the entire sky.
