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...

Modeling Solar Cells on Butterflies

Sunlight is free – if we could just learn how to use it better.  For decades, engineers have been trying to improve the efficiency of solar cells.  Why not look...

Obama and Stem Cells: Hope Chest or Pandora’s Box?

the article clarified in paragraph 6.  “It is the other type of stem cells, embryonic stem cells, that some activists find objectionable, partly because these cells are derived from embryos...

Who Wants Embryonic Stem Cells?

mentioned in the article, however, were from adult stem cells and “induced pluripotent stem cells” (see 11/05/2008), derived from adult somatic cells, that behave “like” embryonic stem cells without the...

How Cells Thread a Needle

...cells do it.  The mechanism was described by Anastassios Economou in Nature this week.1     Cells have to do this kind of thing all the time, so they have...

Selling Stem Cells to Voters

cells.  Researchers in London observed what happened to embryonic stem cells from genetically-engineered mice with an extra chromosome 21.  The study did not use human embryonic stem cells.  Nothing was...

Adult Stem Cells Race Ahead; Embryonics Falter

Major advances are being made with induced pluripotent stem cells (iPS), stem cells reconstituted from adult tissues, while interest in embryonic stem cells (ES) seems to be drying up.  ...

Adult Stem Cells May Cure Muscular Dystrophy

...those who have been watching the debate over embryonic stem cells.  It illustrates the disconnect between the researchers actually finding cures and the scientific establishments who keep pushing embryonic stem...

Stem Cells: It’s a New Ball Game

human embryonic stem cells in research and medicine.  The generation of iPS cells through direct reprogramming avoids the difficult ethical controversies surrounding the use of embryos for deriving stem cells. ...

Will Adult Stem Cells Cure Sickle Cell Anemia?

the wings.     A panel on Fox News reported Saturday that this new stem-cell methodology renders embryonic stem cells obsolete and thus puts the ethical controversy about stem cells...
