Anyone can now make mouse-human chimeras
A newly published how-to guide for making mouse-human chimeras could lead to treatment breakthroughs for countless diseases.
Mouse embryos with beating hearts grown from stem cells
Mouse embryos with muscles, blood vessels, and beating hearts have been grown from stem cells — bringing lab-grown organs closer to reality.
3D-printed liver tissue may be first step to lab-grown organs
A NASA challenge designed to accelerate tissue engineering has announced two winning teams, both of which used 3D bioprinting to create human liver tissue.
Want strong teeth? Eat this candy.
Researchers claim to have invented an experimental breath mint that may renew tooth enamel and strengthen teeth, and it’s already headed into human trials.
Microscopic animals revived after 24,000 years in permafrost
A multicellular animal called the bdelloid rotifer has used cryptobiosis to survive in the Siberian permafrost for at least 24,000 years.
Editing one gene extends mouse life expectancy by 23%
By modifying just one gene, researchers were able to extend the life expectancy of mice by 23%, and they think their results may translate to humans.
The entire human genome has (finally) been sequenced
Researchers have finally sequenced the complete human genome, filling the gaps in the Human Genome Project’s historic first draft.
New lab-grown mini hearts have a human-like beat
Researchers created the first human mini heart in the lab. The mini hearts, called cardioids, have developed distinctly beating chambers, which fire in sync.
Birds, frogs, and reptiles use sound to “program” embryos
Sound appears to play a larger role in animal development than previously thought, affecting how a variety of species prepare for life outside the womb or egg.
"Defective" embryos can actually self-correct in the womb
PGT-A, a genetic test used to screen embryos for aneuploidy prior to in vitro fertilization, appears to be excluding many viable options.
