Researchers have investigated ancient leather balls discovered in the graves of horse riders in northwest China. According to the international research team, they are around 3,000 years old, making them the oldest balls in Eurasia. The find suggests amongst others that the mounted warriors of Central Asia played ball games to keep themselves fit.

Today, ball games are one of the most popular leisure activities in the world, an important form of mass entertainment and big business. But who invented balls, where and when? The oldest balls that are currently known about were made in Egypt about 4,500 years ago using linen. Central Americans have been playing ball games for at least 3,700 years, as evidenced through monumental ball courts made of stone and depictions of ball players. Their oldest balls were made of rubber. Until now, it was believed that ball games in Europe and Asia followed much later:
Working with fish, birds and mice, Johns Hopkins Medicine researchers report new evidence that some animals’ natural capacity to regrow neurons is not missing, but is instead inactivated in mammals. Specifically, the researchers found that some genetic pathways that allow many fish and other cold-blooded animals to repair specialized eye neurons after injury remain present in mammals as well, but are turned off, blocking regeneration and healing.

A description of the study, published online by the journal Science on Oct. 1, offers a better understanding of how genes that control regeneration are conserved across species, as well as how they function. This may help scientists develop ways to grow cells that are lost due to hereditary blindness and other neurodegenerative diseases.
“Our research overall indicates that the potential for regeneration is there in mammals, including humans, but some evolutionary pressure has turned it off,” says Seth Blackshaw, Ph.D., professor of
Researchers at Penn State College of Medicine now better understand the role of a protein, interleukin-21 (IL-21), in the immune system response to infections in the nervous system. The results of their recent study support further investigation into using IL-21 as a therapeutic agent for persistent central nervous system infections.

CD4 T cells in the immune system produce IL-21, which is critical for the development of CD8 tissue-resident-memory (TRM) cells during persistent viral infections of the central nervous system with polyomavirus.
Dr. Aron Lukacher, professor and chair of the Department of Microbiology and Immunology, said the results, published in Science Immunology, demonstrate that IL-21 is an important factor in the development of effective immune responses to chronic infections in the central nervous system including neurodegenerative HIV-AIDS and progressive multifocal leukoencephalopathy (PML), a fatal brain infection caused by JC polyomavirus. PML starts with symptoms including clumsiness, weakness or difficulty speaking

Few positives have resulted from the deadly coronavirus pandemic, but the effect on our Earth is unmistakable. Carbon dioxide emissions have decreased by 5%, and pollution is declining globally. The public’s response to this indicates that there will be a renewed energy toward sustainable initiatives. Once people can safely gather again and live events come back, it’s likely that a new level of concern for the planet will have taken hold, so experiential marketers should plan to evolve now.
Sustainable marketing solutions are the future of the events industry. Eco-friendly event strategies are typically inexpensive and curry favour with attendees, with 28% of people saying they prioritise brands with sustainable or ethical practices. This highlights the need for profitable and financially feasible event practices that marketers can use once events have dialled back up but perhaps the economy hasn’t.
Even before the coronavirus pandemic, the focus of sustainable experiential marketing

“I just ran a little option route on the first touchdown. There was nobody in the zone. Or if it is was man, I was going to go right in there. Since it was zone, I just looked for an open space to get in and (Jeff Sims) threw it me. Luckily, I caught it and scored. The run touchdown, I had some great blocks. Shout out to (tight end Jack) Coco. I did the rest from there. Great blocks downfield from the receivers, too.”
Safety Juanyeh Thomas
On his interception:
“I was just doing my job in coverage. Props to our d-lineman who got the hands on the ball to make it go up and then I had the back and I just came through and scooped it up.”
On responding to the loss:
“We’re just going to get back to work tomorrow. Honestly, we haven’t been here before,

The Yellow Jackets, coming off their heartening 16-13 victory over Florida State, ran into a far better representative of that football-proud state, and lost to the 14th-ranked Knights, 49-21.
But, people, were you not entertained?

Combined, the offenses ran 173 plays and gained 1,131 yards. The majority of the yards – 660 – naturally belonged to the victor.
Central Florida quarterback Dillon Gabriel put up 417 passing yards and four passing touchdowns. And made it look easy.
Glaringly, Tech lost the turnover battle, 5-2. That was not sustainable against such a score-happy opponent.
“We talk about letting go of the rope or holding the rope,” Tech coach Geoff Collins said. “There were times in the second quarter when they went on a run, aided by turnovers, that we let go of the rope.”
More accurately it might be said the rope
