This week in science: hula hoop science, vaccine longevity and 2025 space missions

or less, yes. Bali and his team are now working on a vaccine that would do just that. They’re using a virus that’s been engineered to carry a protein that’s found on megakaryocytes. And they’re hoping that this vaccine will be able to stimulate a stronger antibody response and a longer-lasting immunity. And they’re also looking at other ways to boost the megakaryocyte response, like using a different type of vaccine, like a protein-based vaccine, instead of an mRNA vaccine.SUMMERS: OK, so I’m going to move on to my next story. And I’m going to start with a question. What is the most efficient way to spin a hula hoop?KWONG: I don’t know. I’m going to guess, like, a lot of energy, like a lot of force?SUMMERS: Yeah, I mean, I think that’s what I would have guessed, too. But it turns out that the answer is actually a lot less force than you might think. And this is a question that’s been puzzling scientists for a while. And it’s a question that’s been answered by a team of researchers at the University of California, Berkeley. And they published their findings in the journal Physical Review Letters this month. And they found that the secret to spinning a hula hoop is actually a lot of physics. So the team used a high-speed camera to film a hula hoop in action. And they found that the hoop actually spins in a way that’s similar to how a top spins. So it’s not just the hoop that’s spinning, but it’s also the air that’s spinning around the hoop. And this air is what’s actually providing the force that’s keeping the hoop spinning. And this is a really important finding because it means that the hoop doesn’t need as much force to keep spinning as you might think. And this is important because it means that you can spin a hula hoop for a longer period of time. And it also means that you can spin a hula hoop with less energy.
