Lessons Learned from Tissue Engineering in Urethral Reconstruction and Pelvic Organ Prolapse | Tissue Engineering Part B: Reviews Urogenital diseases, such as hypospadias, incontinence, urethral obstruction, and pelvic organ prolapse, are common conditions that often require treatments at specialized health care providers. All t...

Happy Cucumber Day 🥒🎉
Cucumbers (and other things 😉) come in all shapes and sizes. Big ones, small ones, straight ones, curved ones. Because just like cucumbers, condoms also come in all shapes and sizes. #safesexysummer #cucumber #condoms #cukes #pickles #STIprevention

Biomimetic tubular materials: from native tissues to a unifying view of new vascular, tracheal, gastrointestinal, oesophageal, and urinary grafts Repairing tubular tissues—the trachea, the esophagus, urinary and gastrointestinal tracts, and the circulatory system—from trauma or severe pathologies that require resection, calls for new, more effe...

Two small figures pose for a photo on top of a large telescope dish which reflects the colours of the aurora in the sky over an Antarctic landscape

In a wood, surrounded by trees and tall grass, a researcher wearing outdoor gear and a cap, crouches in shallow water next to a large white box and holds several tiny frogs in open hands

A figure wearing red overalls illuminated in a doorway that appears to open from a black area of trees and buildings, silhouetted by a starry night sky

A researcher wearing high vis jacket and head torch sits in a small boat holding a wide-barrelled air gun. Behind, a fishing trawler surrounded by flocks of sea birds, and snow covered hills on the horizon

These are the striking winners of our 2025 Scientist At Work photo competition, taking viewers on a voyage of discovery that includes the Arctic and Antarctic circles, and a shot from atop a Greek mountain.

🚨 Bladder Cancer: The Forgotten Cancer

This May, let's unite to shift the narrative around bladder cancer. It’s time to elevate awareness, recognise the early symptoms, and dismantle the barriers preventing individuals from seeking the medical advice they need.

‘About as close to aliens as we’ll ever get.’ Can AI crack animal language? Dolittle Prize recognizes breakthroughs in translating “speech” of dolphins, cuttlefish, and other creatures

"Dolphins call each other’s signature whistles if they get separated. Once, we played one of those whistles while the pair was still together. They responded with a totally different whistle. We call it the 'WTF whistle,' because it really did seem like that’s what they were asking." @science.org

Figure group in soft white limestone of a woman and a man with an oversized phallus, dated 305-330 BCE. The nude man is seated, his enlarged phallus extended on ground. A smaller figure of a nude woman playing her harp is seated on the far end of his phallus. The man holds a curious object in front of him – a musical instrument? Some detail are outlined in black paint.

A graphic titled "the body's slow recovery from childbirth" "Researchers examined 76 physiological markers in hundreds of thousands of pregnancies, looking at how look it took for each marker to settle following delivery" ~47% test results stabilished within 1 month of delivery 12% results settle in 4-10 weeks ~41% results take more than 10 weeks to settle

Biologists have built one of the most detailed pictures of pregnancy's true toll on the body.

An eppendorf centrifuge in that specific nicotine-yellow color from the 80s. It's the exact color as the old fridge in your garage that you keep sodas in that your parents replaced in 1997, and which has outlived a half-dozen of its replacements.

"Why don't you buy a new centrifuge"

Because everyone knows that any appliances in that shade of yellow will outlive you and your entire family, look at it

Big shoutout to all patients today in their silent protest, as they are unable to leave the house to make this hiden group visible

Hope science finds a cure and science still get funded for this ❤️‍🩹 #LongCovid #LongCovidAwarenessDay #PACS #COVID19

Petra under blanket with Kees support cat and telephone

I don’t want to make it all about me, as I am one of the lucky few (very few, estimated around 15%) of the patients that recovered from #LongCovid
It was scary, debilitating, lonely and invisible, as I only went out when I was able. Most of the time I was laying like this

a man standing at a counter with an absolutely enormous chocolate penis

idk but this condom tutorial seems to be setting some unrealistic standards

I never thought I could be here today, still in science, leading a group, in the center of regenerative urology #LongCovidAwarenessDay #LongCovid #PACS

Zeker! Heel leuk
