Scientific Supporters of ES Stem Cell Research Fear Future Abuses

...admits that ES stem cells have no track record: “Will therapeutic cloning create immune matching?  It’s unclear.  At this point, we don’t even know if human embryonic stem cells are...

Do ES Stem Cells Prevent Heart Disease?

number of therapeutic successes,* embryonic (ES) stem cells have only been promised to do so – until now.  In Science Oct. 8,1 Cornell scientists coaxed embryonic stem cells to prevent...

Big Science Portrays Embryonic Stem Cell Issue as Political Litmus Test

stem cell discoveries. Giuseppe Testa and John Harris discuss ethical questions of using embryonic stem cells (ES) for reproductive therapies in the Sep. 17 issue of Science.5  Pragmatics include benefits...

Letter: The Case Against Embryonic Stem Cell Research

Sometimes the letters to the editor are the most interesting parts of a magazine.  Read what John T. Durkin says about embryonic stem cell research in response to an April...

Adult Stem Cells Might Restore Hearing

undermine research on embryonic stem cells. While adult stem cells continue to rack up successes, can anyone point to a clear case of embryonic stem cells doing any good?  If...

How Cells Build Hard Parts

...of molecular biology, protein chemistry, nucleation thermodynamics, and crystal growth.  Some organisms build minerals inside cells, outside cells, or between cells.  Davis found one example particularly attractive to the materials...

Stem Cell Cover-Up?

Stem cells, most have heard, hold promise for many life-saving cures.  Michael Fumento in Insight Magazine claims that while adult stem cells have shown many positive results, the media and...

Cells Find Signal in the Noise

...Cells have a novel way of meeting this challenge, as two Japanese mathematical biologists discuss in PNAS.1  Cells are continuously sending and receiving chemical messages, a process called signal transduction. ...

Elaborate Quality Control Governs the Cell’s Protein-Folding Factory

If it weren’t for quality control in our cells, we’d be dead.  That’s the gist of an amazing Insight article in the Dec. 18 issue of Nature.1  “Aberrant proteins are...

Stem Cell Breakthrough

to work with human skin cells.     If this technique bears fruit with real treatments, it could end the need for embryonic stem cells.  National Geographic, however, said it...

Subway System Found in Immune Cells

...new way for immune cells to communicate with one another: long, narrow tubes that enable them to connect and exchange molecules.”  These subway tunnels between cells pass molecules quickly from...

“Genomic Junk” Is Cell’s Air-Traffic Control

...can and do play a leading role.”     Speaking of differences in brain cells and liver cells, another article on Science Daily smashed a paradigm: “DNA Not The Same...

Adult Stem Cells Lead Health Progress

51; Adult stem cells (AS) and induced pluripotent stem cells from adult tissues (iPS) continue to rack up tallies over embryonic stem cells (ESA).  Do we really need the embryonic...

White Blood Cells Walk to Infection on Tiny Legs

51; How do white blood cells know where to go when infection strikes?  The cells have tiny little feet and crawl like millipedes, against the blood stream, if necessary, following...
