3D PRINTING TECH

🖨️ Ultrasound tech prints implants INSIDE the body

The Rundown: Duke and Harvard researchers just devised a technique using focused soundwaves to solidify an injected "ink," enabling non-invasive 3D printing of customized implants deep inside human tissue.

The details:

• The process called DAVP hardens a biocompatible liquid into scaffolds, drug reservoirs, or other structures by targeting it with a specialized ultrasound probe.

• Light can't penetrate skin, so existing bioprinting is limited — but ultrasounds can reach over 100x deeper, allowing inner-body use.

• In tests, DAVP sealed heart tissue, regenerated bone, and printed chemotherapeutic gels in livers without damaging surroundings.

• The technique could enable less invasive surgeries, and enable treatments targeting organs previously unreachable.

The relevance: While we didn’t have 3D printing INSIDE the body on our bingo cards, technology continues to amaze. This research has enormous medical potential if proven safe at scale — opening the door for a wave of new treatments.

TECH TRENDS

📱Teens still hooked on YouTube, TikTok despite backlash

The Rundown: A new Pew Research survey just found that YouTube and TikTok still dominate teens' media diets, with nearly 1 in 5 saying they use each platform "almost constantly" despite proliferating concerns.

The details:

• Among 1,453 surveyed teens ages 13-17, 93% use YouTube and 63% use TikTok. Trailing were Snapchat (60%), Instagram (59%) and Facebook (33%).

• 33% said they use at least one of those apps nearly constantly — and 46% use the internet overall almost constantly.

• While popularity remains high, growth for sites like Facebook and Twitter (now X) has declined over the decade.

Why it matters: For anyone who interacts with teenagers, these numbers shouldn’t come as a surprise. Despite concerns in the media, sites like YouTube and TikTok still have a vice grip on the younger generation (and most of us in general) as the world continues to get more and more digital.
