Specialized Molecules Make Cells Work

Reports continue to show that vital cell processes depend on finely-tuned proteins and RNA molecules.  Most of the papers that discuss these specialized molecules fail to mention how they might...

Stem Cell News: Adults Still Lead

Stem cells are still hot.  Most of the significant findings are coming from adult stem cells (AS) or induced pluripotent stem cells (iPS) rather than embryonic stem cells (ES).  For...

Heal the Blind with Stem Cells

in one eye by burns or acid.  Stem cells taken from the limbus, a disk surrounding the iris, and transplanted onto the damaged cornea, were able to regrow corneal cells...

Stem Cells: Hope, Politics, Charity, and Clarity

or whether adult stem cells, such as induced pluripotent stem cells, could work just as well. An article on both embryonic and induced pluripotent stem cells in Science Daily this...

Stem Cells Promise Regeneration

that none of these stories talked about embryonic stem cells.  Most of the stories about embryonic stem [ES] cells this month discussed efforts to understand how they grow and differentiate...

Stem Cell News: Cancer Cures Coming?

creation and destruction of human embryos and/or the harvesting of human egg cells.  To revisit the shameful news about embryonic stem cells over the last decade, type “embryonic stem cells”...

Dakota Dino Reveals Skin Cells

“Absolutely amazing” and “absolutely gobsmacking” are exclamations made by scientists analyzing the fossilized skin of a hadrosaur known as Dakota.  The researchers found cell structures and organic matter in the...

How Cells Proofread DNA Is Still Mysterious

An amazing fact about DNA transcription is that the machinery not only copies DNA onto RNA, but checks it for errors.  A story in Science Daily says that researchers would...

Cells Use Cloud Computing

...slack if a major server fails.  Scientists are finding that cells have been using this technology all along.     Science Daily reported on work by biologists in Spain and...

Who Needs Embryonic Stem Cells?

is going “fast and furious” on induced pluripotent stem cells, in which adult cells can be made like embryonic stem cells without the need to create and destroy human embryos. ...

Dinosaur Blood Protein, Cells Recovered

unknown is the chemistry behind such preservation. The paper also includes photographs of structures that resemble cells.  While they were cautious not to call them cells, they sure look like...

Better Solar Cells with Diatoms

...of the most advanced materials in the world.”  OK, now the subject: how to build better solar cells, by imitating diatoms.  See the story on Science Daily.     The...

Stem Cells Polarize Ethics

embryonic” and just talk about “stem cells,” but there is a big difference in the ethics of one over the other.  Embryonic stem cells require harvesting a human embryo. Adult...

Elect Obama, Get Embryonic Stem Cells

to generate cells from many adult tissues such as a patient’s own skin cells.” ESC is not completely without promise.  Science Daily reported that embryonic stem cells are being studied...

Adult Stem Cells, +2; Embryonic Stem Cells, -1

begin to take their stem cell research toward therapeutic treatments.     Not so good for embryonic stem cells.  Nature News reported, “Hybrid embryos fail to live up to stem-cell...
