College student uses AI to help 11 missing children return home
The AI Baby Volunteer Service Team of the School of Software of Huazhong University of Science and Technology uses professional knowledge to develop image restoration algorithms to turn blurry family-seeking photos into clear and large pictures. They turned the photos into family tracing tape and stuck them on the express delivery. They also made postcards, short videos, etc. to facilitate the dissemination of information. In the past three years, college students have restored photos of more than 1,000 missing children and helped reunite 11 children with their families.
Recently, "nasal energy bars" have gradually become popular among primary and secondary school students. It is two rod-shaped plastic tubes that can be inserted into the nostrils. The price ranges from a few yuan to more than ten yuan, and its sales on e-commerce platforms are very impressive. Merchants claim that it has a refreshing effect and is "pure and non-toxic", and some even advertise that it is "suitable for students". Doctors said that "nasal energy bars" are added with menthol and borneol, which are irritating and exciting and can cause insomnia, anxiety, and depression. Some also add spirits, which have an anesthetic effect and can cause hallucinations in severe cases. Yao Hua, director of the Institute of Sociology of the Guangxi Academy of Social Sciences, believes that regardless of its ingredients, the use of "snorting energy bars" will reduce the student population's psychological defense against drugs.
The lip-syncing controversy at the famous band’s Mayday concert continues.
On December 5, Sun Yuhao, a senior partner at Haihua Yongtai Law Firm, told a reporter from Beijing Business Daily that there are some difficulties in obtaining evidence for lip-synching. Sometimes, for the sake of performance or harmony, there will be a half-open mic at the performance, which requires technical screening to determine whether there is lip-synching.
At the same time, Sun Yuhao said that according to relevant laws and regulations, there is no problem in classifying lip-synching as consumer fraud. If consumers believe that lip-syncing occurs in the concert, they can claim compensation. For consumers, they can make compensation claims to ticketing agencies and ticketing agency platforms. The parties responsible for compensation include performers, organizers, undertakers, actors’ management teams, brokerage companies, performance groups, etc.
Japan: Rising gold prices fuel recycling of scrap home appliances
The international gold price has surged recently, and the retail price of gold in Japan in yen has also reached a new high, which has driven the domestic demand for "urban mines" in Japan. The so-called "urban mines" refer to various types of waste electronic products, from which a variety of metals, including gold, can be extracted.
Japan's Ministry of the Environment estimates that 10,000 old mobile phones weigh about 1 ton and can recover about 280 grams of gold. This refining efficiency is 56 times that of gold mining. In addition, according to Japanese media reports, unscrupulous merchants in Japan have recently targeted elderly people living alone and forcibly purchased gold. An 80-year-old man in Nagasaki Prefecture was forcibly bought gold jewelry by an unscrupulous merchant at a low price of approximately more than 1,400 yuan.
Recently, a 42-year-old woman shared her appearance changes in just 20 days on a short video platform, saying that she had experienced "cliff-like aging" and attracted a lot of attention.
The video shows that the woman has haggard eyes, obvious facial wrinkles and severe facial sagging, which is in sharp contrast to her bare face appearance 20 days ago, as if she has aged 10 years overnight.
In fact, this feeling is not "unfounded". The body undergoes quantitative changes to qualitative changes at a specific point in time. In fact, as early as 2019, a study published in "Nature Medicine" proposed the view that "aging is not uniform, but has three physiological turning points." The study stated that it is based on the ups and downs of the plasma proteome in the human body. The ages at which "cliff aging" occurs in a person's life are 34, 60 and 78 years old respectively.
