You need to create an industry before you bother with competition. Right now everything is a test, a prototype or demands much tweaking. Once applications and real orders become meaningful, larger companies will either buy in the winners or commit real money to RD. will these companies be the survivors? Perhaps. But having larger companies in the sandbox is a good thing! It legitimizes the space. The more the merrier. Perhaps 10 years from now the next Microsoft/intel/Qualcomm will arise or go the way of LED lighting. Plenty of money to be made in the meantime. Good luck in the space.
Infertile mice have given birth to healthy pups after having their fertility restored with ovary implants made with a 3D printer. Researchers created the synthetic ovaries by printing porous scaffolds from a gelatin ink and filling them with follicles, the tiny, fluid-holding sacs that contain immature egg cells. In tests on mice that had one ovary surgically removed, scientists found that the implants hooked up to the blood supply within a week and went on to release eggs naturally through the pores built into the gelatin structures. The work marks a step towards making artificial ovaries for young women whose reproductive systems have been damaged by cancer treatments, leaving them infertile or with hormone imbalances that require them to take regular hormone-boosting drugs. Of seven mice that mated after receiving the artificial ovaries, three gave birth to pups that had developed from eggs released by the implants. The mice fed normally on their mother's milk and went on to have healthy litters of their own later in life. Writing in the journal Nature Communications, the scientists describe how they printed layered lattices of gelatin strips to make the ovary implants. The sizes and positions of the holes in the structures were carefully controlled to hold dozens of follicles and allow blood vessels to connect to the implants. Mature eggs were then released from the implants as happens in normal ovulation.
CHICAGO - The new world of 3-D printed organs now includes implanted ovary structures that, true to their design, actually ovulate, according to a study by Northwestern University Feinberg School of Medicine and McCormick School of Engineering.
By removing a female mouse’s ovary and replacing it with a bioprosthetic ovary, the mouse was able to not only ovulate but also give birth to healthy pups. The moms were even able to nurse their young.
The bioprosthetic ovaries are constructed of 3-D printed scaffolds that house immature eggs, and have been successful in boosting hormone production and restoring fertility in mice, which was the ultimate goal of the research. ...
Rocket Lab has delayed for a day the start of a launch-attempt window to send its Electron rocket into space from its base in Mahia on the East Coast.
It says high winds on the peninsula have forced it to have another go tomorrow.
The company has said weather and other technical factors will dictate whether the test launch can be attempted and what one local described as a nasty southerly blew through at the weekend and will hang around early today.
The wind is forecast to be blowing from the southwest and more an 20km/h from the southwest this morning.
