Stem Cell Breakthrough
In an "important step" in stem cell research, scientists have for the first time succeeded in creating human embryonic stem cells by injecting DNA from a skin cell into an unfertilized egg.
What's the Latest Development?
For the first time, researchers have succeeded in creating human embryonic stem cells by injecting DNA from a skin cell into an unfertilized egg. To achieve what is being called an "important step" in stem cell research, scientists in New York used a cloning technique similar to the one used to make Dolly the sheep.
What's the Big Idea?
The work shows for the first time that the human egg has the ability to turn a specialized cell into a stem cell, said one of the study authors. The goal of the research was to create patient-specific embryonic stem cells with the patients' DNA for later use in cell replacement therapy. Why? To eventually cure diseases such as Parkinson's and diabetes, and many other illnesses.
New research links urban planning and political polarization.
- Canadian researchers find that excessive reliance on cars changes political views.
- Decades of car-centric urban planning normalized unsustainable lifestyles.
- People who prefer personal comfort elect politicians who represent such views.
It turns out the human scalp has an olfactory receptor that seems to play a crucial role in regulating hair follicle growth and death.
- Scientists treated scalp tissue with a chemical that mimics the odor of sandalwood.
- This chemical bound to an olfactory receptor in the scalp and stimulated hair growth.
- The treatment could soon be available to the public.
Science and the squishiness of the human mind. The joys of wearing whatever the hell you want, and so much more.
- Why can't we have a human-sized cat tree?
- What would happen if you got a spoonful of a neutron star?
- Why do we insist on dividing our wonderfully complex selves into boring little boxes
