Mexico City’s residents set a new Guinness World Record on Saturday after taking part in the boxing class with the largest attendance worldwide.
With jabs, crosses, uppercuts, and hooks, a total of 14,299 people met early in the morning at the city’s Zocalo square to take part in the lesson.
Moscow was the last city to break the record in 2017 when 3,000 people showed up for the event.
Mexican boxing champions, such as Mariana Juarez, Ana Maria Torres, and David Picasso, led the massive 30-minute class while attendees formed a mosaic by wearing green, white, and red shirts, the colors of Mexico’s flag.
The event was organised by the Mexico City government and the World Boxing Council.
Former President Donald Trump wished current President Joe Biden well after Biden took a tumble off his bicycle earlier on Saturday.
“But, no, we do hope that Biden is ok. Because that was a hard fall. That was scary. Did anybody see it? Well, we wish him well in that respect,” said Trump, speaking at a rally in Tennessee.
Biden took a spill from his bike on Saturday as he stopped to greet supporters during a weekend trip to Rehoboth Beach, Delaware.
He appeared to be uninjured after standing up immediately. “I’m good,” Biden, 79, said after the tumble, which occurred in front of reporters. “I got my foot caught up,” he said.
The president, who was wearing a bike helmet, said the toe cages on his bike should be removed after his foot got caught before he could steady himself.
Later, Biden spent several minutes chatting with people who had gathered to watch him bike.
Biden and first lady Jill Biden were finishing up a morning bike ride in the Gordons Pond area on the Delaware shore. They marked their 45th wedding anniversary on Friday.
The White House said the president did not require medical attention.
Asked how he was feeling while emerging from church later on Saturday, Biden did a series of hops before entering his vehicle.
A new study by scientists revealed that the human ear evolved from fish gills, with evidence gathered from 400-million-year old fish fossils found in China.
The human middle ear—which houses three tiny, vibrating bones—is key to transporting sound vibrations into the inner ear, where they become nerve impulses that allow us to hear.
Chinese scientists have eventually found clues to the mystery in fossils unearthed in the provinces of Zhejiang and Yunnan, which provided anatomical and fossil evidence for the origin of vertebrate spiracles from gills.
According to Gai Zhikun, a Chinese Academy of Sciences researcher and the first author of the article “The Evolution of the Spiracular Region From Jawless Fish to Tetrapods,” there is ample embryonic and fossil evidence that the human middle ear evolved from a fish’s spiracle.
“The discovery of these ancient fish fossils is proof that our middle ears originated from fish gills. It explains why human ears don’t breathe today, but they’re still connected to the mouth, because they used to be the organ of fish’s respiratory system,” said Gai.
The “ancient fish kingdom” of Qujing in southwest China’s Yunnan Province was ocean from Silurian to Devonian. During excavations of fossils in the early Devonian strata, the research team collected the first fossil material of broad-shelled turtle with intact gill-filaments marks. It provides the most accurate anatomical and fossil evidence for the theory that the spiracle of vertebrates such as fish originates from degenerated gills.
“Many human body structures can be traced back to the ancestors of fish, such as our teeth, jaws and middle ears. Paleontologists are filling in important processes in the chain of evolution from fish to humans. The fossil of Qujing ancient fish kingdom provides important evidence for the improvement of this chain,” said Zhu Min, researcher of Institute of Vertebrate Paleontology and Paleoanthropology under CAS.
The research team proposed the evolution process of the spiracle from jawless fish to tetrapod on the basis of the fossils, thus establishing the evolutionary sequence of the spiracle from the gills of jawless fish to the middle ear of human.
Experts believe that as fish evolved and landed on ground, they had to develop new senses to survive better in the air. The spiracle, which had lost its ability to breathe, gradually evolved into the middle ear, becoming the hearing canal used for transmitting sound to the brain via tiny inner ear bones. Thus, humans evolved acute hearing.
Amid a recent string of mass shootings in the United States, the City of Miami in collaboration with the Miami-Dade Police Department held a gun buyback event Saturday.
Earlier in the week, District 2 Commissioner, Ken Russell announced the program with a tweet describing the buyback event to “support Ukraine and take guns off the streets.”
As gates opened on this warm Saturday morning, three cars lined up. One of the first donations was delivered in a blue plastic bag and appeared to be a hand-made weapon of pipe and tape.
The “no questions asked” aspect of the event is meant to encourage getting weapons off the streets, according to Commissioner Russell. “No guns will be sent to Ukraine that are not appropriate or not wanted or not useful in their efforts against defending against Russia,” says Russell. He has partnered with the State Department and an exporter to be able to ship the approved firearms to the Ukraine.
The buyback program has its skeptics among gun enthusiasts in Florida. Leadership at Florida Carry Inc, a non-profit organization that promotes gun rights, believe the practice is deceptive.
“I think it’s a bait and switch. What the Miami Police Department is not telling people is they have four options that they can do with firearms that are turned in,” said Florida Carry board member, Kevin Sona, “they can keep them, they can destroy them, they can lend them to another department or they can sell them and any sales, the funds from those sales have to go back into the Florida school funding.”
Sona and another program skeptic carefully documented the event with photos and video. “Glory for Ukraine” one man yelled, while claiming the department and the city officials were dishonest in saying they will ship the weapons to Ukraine. Commissioner Russell spoke to the group in an effort to assure them officials are trying to contribute to defense efforts in Ukraine and keep guns off the streets in Miami.
The Miami-Dade Police Department told Reuters via email, that a resolution from the City of Miami passed on June 9 directs officials to “take any and all action to work with federal authorities to ship any functional weapon received through the city’s Gun Buyback program to Ukraine for use in the conflict against the Russian invasion.” While the police department does not possess a license to export firearms, the city’s resolution says it may include procurement of an export license in order to stay within Arms Export Control Act (AECA) and International Traffic in Arms Regulations (ITAR) along with the Department of State’s Directorate of Defense Trade Controls in regards to any and all exports of firearms. Commissioner Russell confirmed to Reuters the exporter with which they are partnering possesses those necessary licenses to comply with federal laws.
Those who chose to give away their guns said they want a safe way to get rid of them.
“My brother in law passed away and I thought that this was the safest way to get rid of guns because I don’t do guns,” said Anna, who preferred not to share her last name. “I’ve been storing them in a safe place until the gun buyback program surfaced again.”
Nepal is considering relocating the base camp of Mt. Qomolangma, possibly a little below its current location at 5,364m, as human activity accelerates the melting of glaciers.
Nepal’s government is considering relocating the base camp of Mt. Qomolangma, the world’s highest mountain, as increasing human activities in the area have contributed to a rapid melt of ice, officials said on Friday.
“The discussions regarding shifting the base camp have started,” Surya Prasad Upadhyay, information officer at the Department of Tourism, told Xinhua. “No decision on moving the base camp has been taken yet.”
Every year, hundreds of climbers from around the world assemble at the base camp, located at 5,364m on the Khumbu Glacier, with a view to standing on top of the world.
The climbers have experienced growing changes around the base camp, since they have been able to collect water directly in recent years, instead of collecting ice to boil in huge pots to make water.
Officials at the Tourism Department said that internal discussions have been ongoing after a task force was formed to explore better ways of organizing the expeditions. A member of the task force told Xinhua that they have submitted a draft of recommendations to the department suggesting moving the base camp a little below its current location.

Bhisma Raj Bhattarai, a section officer at the department, said growing human activities, including cooking at the base camp, have contributed to a warming environment on the 8848.86-meter-high Mt. Qomolangma that straddles Nepal and China.
“Melting snow has also put human lives at more risk,” he added.
Khim Lal Gautam, member secretary of the task force, said they also suggested moving the base camp to another location to avoid direct contact between humans and the Khumbu Glacier.
Gautam, who ascended Mt. Qomolangma in 2011 and 2019 as a surveyor to measure the height of the peak, said climate change is remaking the entire landscape of the region.
