Mars May Have Been Wet, But Never Lively
September 27, 2013
Astrobiologists got excited with evidence for early water on Mars, but other discoveries are putting the quash on hopes it has or had life.
Induced Stem Cells Get Faster, Better, Cheaper
September 24, 2013
Scientists have not only made the production of induced pluripotent stem cells much more efficient, but also have made them just as capable as embryonic stem cells of being able to produce any cell type.
Reverse Engineer Living Solutions
September 20, 2013
Need solutions to practical engineering problems? Save time and effort; see how animals and plants do it.
"Evidence-Based" Findings May Not Be
September 12, 2013
Patients are encouraged to seek only "evidence-based" treatments for disease, but a look behind the scenes of clinical trials reveals some of the same human foibles that plague any science: shortcomings in honesty and transparency.
More Reasons to Love Plants
September 10, 2013
For food, for visual pleasure, and for the health of the whole planet, plants are worth loving and learning about.
Ethical Stem Cells Can Be Used Unethically
September 1, 2013
Induced pluripotent stem cells allow researchers to ethically create any cell type from an adult cell, raising hopes for regenerative medicine. Eyebrows started to raise recently, though, when labs grew brains with them and turned others into sperm and egg cells.
Psychotherapy Has a Shrink
August 27, 2013
For better or worse, the practice of psychotherapy is shrinking, reports say.
Stem Cell Science Can Proceed Ethically
August 19, 2013
With adult and induced pluripotent stem cells in abundance, it should not be necessary to destroy human embryos to understand stem cell science.
More Evidence for Epigenetic Controls on Genetics
July 31, 2013
Epigenetics has become a hot topic in biology. There are players "above DNA"– some heritable – that may be more important than the genetic code itself.
Amazing Cures from Adult Stem Cells
July 29, 2013
Regrowing organs and other miracle cures may be coming to a hospital near you, thanks to progress with adult stem cells.
From Hunter-Gatherer to Modern Farmer
July 28, 2013
Here are some headlines concerning early man and the ongoing struggle by humans to improve life.
Engineers Chase Animals
July 26, 2013
Inspired by the wisdom inherent in living organisms, inventors and engineers are finding bright ideas.
Stem Cell Wars Continue
July 14, 2013
The race continues between scientists desperately seeking a rationale for harvesting human embryos and those who say, having adult stem cells and iPS cells available, they are unnecessary – and their use is unethical.
Muscle Power Is Designed, Not Evolutionary
July 13, 2013
The wonder of muscle inspires both awe at its design and opportunities for evolutionary storytelling.
New Biomimetics Projects
July 7, 2013
These recently-reported attempts to mimic nature show that the biomimetics revolution continues, with no end in sight.
