NEWS CENTER/ 17-year-old Ángela Karime Venegas Hernández developed a fire extinguisher that can extinguish flames in seconds using low-frequency sound waves. A young Mexican girl won a gold medal for her country at the International Science and Invention Fair in Indonesia with her fire extinguisher called Vortex Tech.
The young girl, who had previously won awards in state and national competitions, made her reputation known internationally with this fair held in Southeast Asia between 14-16 October with her device.
According to Mexican media El Pais, the young girl stated that this idea emerged after watching a video of DARP (US Defense Advanced Research Projects Agency) extinguishing a flame through a sound wave using a four-meter sound cannon.
HOW DOES THE DEVICE WORK?
The acoustic fire extinguisher consists of a 12-volt battery, a frequency generator, a speaker, a bucket that acts as a barrel, an amplifier and a speaker. The device produces a low frequency of 30 hertz per second, which the speaker converts into sound waves and pushes them towards the exit of the ball (a circular window). This creates a little turbulence in the air (vortex rings, a turbulent, ring-shaped flow that can be liquid or gas) and removes the oxygen that fuels combustion.

King's College London researchers discovered that variants in the C2CD3 gene lead to dental anomalies. The study elucidates the critical role of the Sonic hedgehog signaling pathway in tooth development and the genetic mechanism of the process of birds losing their teeth.

Glacial melting caused by climate change unearths thousands of years of archaeological remains, such as Ötzi the Iceman. Experts point out the urgency of rescue efforts, stating that these works carry the risk of rapid deterioration.

In the study published in the journal Nature, the genetic mutation that caused Wilson's disease was corrected directly within the body by the 'primary editing' method. This method leaves behind costly processes that require cell modification in the laboratory.

The research published in Nature created an anatomical map of Denisovans based on fossils from Xujiayao. The study proves that the species was a bridge between modern humans and Homo erectus and had advanced hunting skills in East Asia.
In the EU-supported RoboRoyale project, in which researchers from Turkey, England, Czechia and Austria participated, it is aimed to increase pollination activities and agricultural productivity by supporting honey bees with artificial intelligence and micro robotic systems.
Nobel Prize-winning scientist Aziz Sancar stated that turning his childhood home in Mardin Savur into a museum and library was an indescribable happiness for him and wished it to be an inspiration to young people.
