Tissue engineering has long-depended on geometrically static scaffolds seeded with cells in the lab to create new tissues and even organs. The scaffolding material usually a biodegradable polymer structure is supplied with cells and the cells, if supplied with the right nutrients, then develop into tissue as the underlying scaffold biodegrades. But this model ignores the extraordinarily dynamic morphological processes that underlie the natural development of tissues.
Now, researchers at the University of Illinois Chicago have developed new 4D hydrogels 3D materials that have the ability to change shape over time in response to stimuli that can morph multiple times in a preprogrammed or on-demand manner in response to external trigger signals.
Researchers looked at atheists and religious people in the US and Sweden
Both believers and non-believers are concerned with fairness and kindness
But atheists don t think respect for authority or group loyalty are necessary to be moral
Religious people are more likely to believe the world is a dangerous place
Atheists differently calibrated moral compass may explain the belief that they re immoral
Atheists aren t less moral than religious people, study finds Dan Avery For Dailymail.com
Are atheists immoral because they don t believe in God?
It s a commonly held stereotype, but a new study suggests they re no less principled than religious people.
Researchers found non-believers and believers shared similar views on fairness and not hurting people.
But the atheists didn t see values that supported unity, like loyalty and respect for authority, were essential to be moral.
Non-believers also tended to think more about the consequences of an action when deciding if something was moral or not, and were more likely to make a judgment on a case-by-case basis.

New hydrogel-based materials that can change shape in response to psychological stimuli, such as water, could be the next generation of materials used to bioengineer tissues and organs, according to a team of researchers at the University of Illinois Chicago.
