In insects the mechanism is fairly well understood. A fly with XX chromosomes will be a female.
However, an embryo that loses a Y chromosome still develops into what looks like an adult male, although it will be sterile.
It’s thought that bilateral gynandromorphism occurs when two sperm enter an egg. One of those sperm fuses with the nucleus of the egg and a female insect develops. The other sperm develops without another set of chromosomes within the same egg.
Both a male and a female insect develop within the same body.

California-based artist Tim Hawkinson is known for taking everyday materials and altering them in imaginative ways, creating works that address broad issues about the intersection of human consciousness, nature and technology.
Here, he employed a mix of found objects and common household materials—including twist ties, craft wood, staples, and packing material—which he transformed almost alchemically into a complex and awe-inspiring sculpture.
Echoing the working methods of ship-in-a-bottle hobbyists, Hawkinson created a painstakingly detailed model ship that twists in upon itself, presenting the viewer with a thought-provoking visual conundrum.

Drexel’s Wei Sun, PhD, Albert Soffa chair professor in the College of Engineering, has devised a method for 3D printing tumors that could soon be taking cancer research out of the petri dish.
Using a mixture of cervical cancer cells and a hydrogel substance that resembles an ointment balm, Sun can print out a tumor model that can be used for studying their growth and response to treatment.
And here I thought I was getting blasé and ho-hum about the possibilities of 3D printers.
Organs? Whatever. Buildings? Done that. Cancer cells?
