DanceyourPhD, this magical competition has been held for the tenth time this year. This dance competition requires PhD /PhD students to bring together their buddies to perform their research projects with the most creative dance. These two days, this year's award-winning works have just been announced, and I still bring you to enjoy one of my favorite

Who doesn’t want to look better in her favorite cheap sexy wedding dresses? Your dream garment is just a mouse click away.

. This year, I think the most coquettish dance is the award-winning work of the chemistry group. The theme is: biosensors for crime scene detection.

Let's enjoy the video first:

the following is a textual explanation:

when violent crimes are committed, traces of body fluids (such as blood) left at the scene are important clues. In the past, there have been many ways to detect these traces, such as the luminol reaction, which has been used to detect blood.

what should I do at this time? People need new testing methods, and the protagonist of this video, PhD Na á lia Oliveira of the Federal University of Pernambuco, Brazil, is doing this research. She is committed to developing biosensors for detecting body fluid traces, which are highly sensitive and specific, so they are suitable for use at crime scenes.

experiments show that this method is still effective in the environment with bleach and detergent. In other words, even if the criminal cleaned the scene, it is still possible to find clues.

other award-winning works

this year's champion is a beautiful dance with a mathematical theme, showing a theme of Braid Groups. The "braid" structure composed of several strands of rope twisted together is very common in life, while mathematical PhD Nancy Scherich uses matrices to study "torsion" and "knots" in high-dimensional space.

(after reading, I don't understand _ (: dance "∠) _)

the award-winning works of the social science group explore which factors influence people's judgment of" creativity "(but the dance feeling is a little unclear). ).

the works of the biological group show that the death of a large number of starfish has brought a lot of impact on their ecological environment.

how about it? do you feel like dancing after watching it?
