Ty Haney is doing things differently this time
Kevin Werbach of the Wharton School said “web3,” a block-chain-centered iteration of the internet, won’t be as democratized or utopian as some believe. “There’s a web3 that’s out there which is wonderful and trying to make the world a better place, but just by labeling something web3, it doesn’t mean power dynamics will magically reverse,” Werbach said.

Why some fluids flow slower when pushed harder
Paulo Arratia of the School of Engineering and Applied Science commented on a study that explored how fluids flow under different pressures. “Visualizing flow inside a 3-D porous media literally gives a window into something that was impossible to see,” he said. “If you could actually see the molecules stretching and recoiling, that would be wonderful [to] connect the molecular point of view to the microscopic.”

Why the global chip shortage threatens the economy, national security and Americans’ ‘status quo’
Morris Cohen of the Wharton School spoke about the semiconductor shortage. "Most consumers didn't know and didn't care where their chips came from: 'You turn the car on, it should go, I don't really care who made the chip and what country it was built in,'" he said. "But now, all of a sudden, these issues become really important, and so I think we become more sensitized to how dependent we are, how interdependent we are, how things can be disrupted."

The inner lives of cats: what our feline friends really think about hugs, happiness and humans
Carlo Siracusa of the School of Veterinary Medicine said cats are capable of bonding with people, contrary to claims that they’re merely using their owners for food and shelter. “Humans hug and kiss. Dogs become very excited and jump around. Cats don’t do anything like that. They are much more elegant,” he said. “They approach us. They bump their heads. Then they have some contact with us and walk away.”

Can a digital reality be jacked directly into your brain?
Researchers led by Daniel Yoshor of the Perelman School of Medicine are developing better electrode arrays, which are used to induce neural activity. Current arrays approved for human use are bulky and contain around 1,000 electrodes, whereas the arrays Yoshor and colleagues are working on would have 64,000 electrodes, and eventually 1,000,000 electrodes.
