There are just two northern white rhinos left in the entire world – and they're both female. But now, their species has a chance at survival, as researchers have for the first time achieved an IVF rhino pregnancy.

BioRescue Project, a reproduction technology nonprofit focused on saving threatened species, announced on Wednesday that the company saw the "world's first successful embryo transfer in rhinos." Achieving the feat, the company says, "paves the way for saving the northern white rhinos from extinction."

White rhinos as a whole have seen declining numbers, largely due to poaching, the International Rhino Foundation says. There are two subspecies – the southern white rhino and the northern white rhino – the latter of which is considered extinct in the wild. Just two northern white rhinos remain in the world and reside in a 700-acre enclosure at Kenya's Ol Pejeta Conservancy, where they have 24-hour armed security.

The embryo was not placed in one of the northern white rhinos. Instead, a southern white rhino embryo was produced and transferred into a southern white rhino surrogate mother at the conservancy. The embryo was placed on Sept. 24, BioRescue Project said, adding that they confirmed a pregnancy of "70 days with a well-developed 6.4 cm long male embryo."

    How come you're so into recipes lately? Never saw this much interest in this topic in the old days of TH.net

    Hmm, how do I change my signature?
  • tom_mai78101 tom_mai78101:
    Signatures can be edit in your account profile. As for the old stuffs, I'm thinking it's because Blizzard is now under Microsoft, and because of Microsoft Xbox going the way it is, it's dreadful.

    @tom_mai78101 I must be blind. If I go on my profile I don't see any area to edit the signature; If I go to account details (settings) I don't see any signature area either.

    I think I need to split the Sci/Tech news forum into 2 one for Science and one for Tech but I am hating all the moving of posts I would have to do

    Crazy how much 3d printing has come in the last few years. Sad that it's not as easily modifiable though
  • Varine Varine:
    I bought an Ender 3 during the pandemic and tinkered with it all the time. Just bought a Sovol, not as easy. I'm trying to make it use a different nozzle because I have a fuck ton of Volcanos, and they use what is basically a modified volcano that is just a smidge longer, and almost every part on this thing needs to be redone to make it work
  • Varine Varine:
    Luckily I have a 3d printer for that, I guess. But it's ridiculous. The regular volcanos are 21mm, these Sovol versions are about 23.5mm
  • Varine Varine:
    So, 2.5mm longer. But the thing that measures the bed is about 1.5mm above the nozzle, so if I swap it with a volcano then I'm 1mm behind it. So cool, new bracket to swap that, but THEN the fan shroud to direct air at the part is ALSO going to be .5mm to low, and so I need to redo that, but by doing that it is a little bit off where it should be blowing and it's throwing it at the heating block instead of the part, and fuck man
  • Varine Varine:
    I didn't realize they designed this entire thing to NOT be modded. I would have just got a fucking Bambu if I knew that, the whole point was I could fuck with this. And no one else makes shit for Sovol so I have to go through them, and they have... interesting pricing models. So I have a new extruder altogether that I'm taking apart and going to just design a whole new one to use my nozzles. Dumb design.
  • Varine Varine:
    Can't just buy a new heatblock, you need to get a whole hotend - so block, heater cartridge, thermistor, heatbreak, and nozzle. And they put this fucking paste in there so I can't take the thermistor or cartridge out with any ease, that's 30 dollars. Or you can get the whole extrudor with the direct driver AND that heatblock for like 50, but you still can't get any of it to come apart
  • Varine Varine:
    Partsbuilt has individual parts I found but they're expensive. I think I can get bits swapped around and make this work with generic shit though
  • Ghan Ghan:
    Heard Houston got hit pretty bad by storms last night. Hope all is well with TH.
