Contact Lenses Grant Infrared Vision

Researchers have created contact lenses enabling people to see infrared light, even with closed eyes.
The lenses use nanoparticles to convert near-infrared light into visible shorter-wavelength light, creating multi-colored infrared images.
Unlike night-vision goggles, these lenses don't amplify light, requiring brighter infrared sources.

Scientific Conferences Leaving the US

Several conferences scheduled in the US have been postponed, canceled, or relocated due to concerns about border crossings, funding cuts, and restrictions on federal scientists.
The International Society for Research on Aggression moved its conference due to these concerns.
Some major conferences, like the American Society for Microbiology (ASM) meeting, are proceeding as planned.

Epigenetics and Evolution in Rice Plants

Rice plants can inherit cold tolerance through epigenetic modifications to DNA markers without changing the DNA sequence itself.
This challenges the idea that natural selection is the only driver of evolution, suggesting environmental pressures can induce heritable changes.

Private Funding for Science

Philanthropic grants can supplement but not replace federal funding for science.
Private funders can support high-risk, early-stage research with the potential to transform science and technology.
Lisa Fazio suggests private funders could provide continued funding for canceled National Science Foundation grants, which have already undergone peer review.

Podcast: Malaria Mosquito Treatment

Researchers have developed compounds that kill malaria-causing parasites within mosquitoes.
These compounds can be incorporated into bed nets, potentially reducing malaria transmission.
Tests show the compounds provide lasting protection, reducing the chance of mosquitoes becoming infected with malaria parasites.

Script

Mars: Ever watched those movies where characters see heat signatures? Like, ripples of warmth just hanging in the air? Well, turns out some scientists are close to making that real – infrared vision contact lenses! And that’s just one piece of the puzzle we're diving into today. We’re also gonna chat about why some big science conferences are ditching the US, and a new way to kill malaria… inside the mosquito itself! Sounds crazy, right? Let’s get into it.

Mia: Totally wild, but yeah, happy to unpack it all.

Mars: Okay, so these infrared contacts… how do they even WORK? Are we talking Terminator vision, or is it more like, uh, a really intense Instagram filter?

Mia: Haha! More like a smart filter. Basically, they embed tiny nanoparticles into the lens. When near-infrared light hits them, they down-convert it. Think of it like turning invisible light into visible colors. So you see a multi-colored map of infrared energy. Mind-blowing, right?

Mars: It IS! I'm guessing I can't just grab a pair of these at the drugstore? What’s the catch?

Mia: Well, unlike night-vision goggles, which amplify faint light, these don’t boost brightness. They just shift the wavelengths. So you need a pretty strong infrared source. Think industrial laser pointers, or dedicated IR lamps. And yeah, they're still early stages. Comfort, safety… all that needs work before you're rocking them at a barbeque.

Mars: Right, right. Still, the idea that my eyeballs could SEE heat…that's a game changer.

Mia: Exactly. Could help firefighters spot hotspots through smoke, or mechanics find overheating parts without dragging around a ton of equipment.

Mars: Speaking of equipment, let’s switch gears to academia. I heard some US science conferences are packing up and leaving. What’s THAT about?

Mia: It’s a few things. Border-control red tape, worries about visa denials for international scientists... funding cuts, plus just a general feeling that policy is becoming less science-friendly. I heard the International Society for Research on Aggression decided it wasn’t worth the hassle and moved overseas.

Mars: Ouch. But not EVERY event is leaving, right?

Mia: No, no. Big conferences like the American Society for Microbiology are still happening here. They've got deep pockets and plan years in advance. But the mid-tier ones, the ones without huge budgets, are feeling it the most. Travel restrictions mean fewer attendees, which means less money… kind of a spiral.

Mars: You worry about the ripple effects… lost networking, slower collaboration.

Mia: Totally. Science thrives on those face-to-face brainstorms – in hallways, over coffee. Virtual meetings are okay, but you miss those random Hey, I have an idea! moments.

Mars: Yep. Alright, last stop: malaria mosquito killers. What's the deal there?

Mia: This is clever. Instead of killing the mosquito, researchers are working on compounds that kill the malaria parasite INSIDE the mosquito when it bites a treated bed net. So the mosquito lives, but it can’t spread the disease.

Mars: Wait, so the mosquito lives, but the parasite dies? That’s like… cutting the head off a rumor without hurting the town crier!

Mia: Love that metaphor! Exactly. And the tests show these compounds stay on the net fibers for months, offering long-lasting protection. When a mosquito feeds, it gets just enough to stop the parasite's life cycle.

Mars: Any idea how the cost compares to regular insecticide nets?

Mia: Early estimates say it could be competitive, especially since it avoids insecticide resistance. No need to keep upping the chemical doses. Plus, it's a double-whammy: the nets still block bites, AND the compound stops transmission if a bite gets through.

Mars: Sounds like it could be a real game-changer in high-risk zones.

Mia: For sure. It's another weapon in our malaria-fighting arsenal.

Mars: Alright, so we’ve covered infrared eyeballs, conference migrations, and parasite-zapping bed nets. Anything else you want to throw in before we wrap up?

Mia: Just that it's amazing to see how diverse and creative science can be – from reshaping evolution to reshaping what our eyeballs can do. Keeps you on your toes, you know?

Mars: Couldn't agree more. Thanks for walking us through all that. And to our listeners, watch out next time you see someone blinking strange colors – it might not be a filter! Talk soon.
