Mars May Have Been Wet, But Never Lively

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

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

Need solutions to practical engineering problems? Save time and effort; see how animals and plants do it.

"Evidence-Based" Findings May Not Be

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

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

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

For better or worse, the practice of psychotherapy is shrinking, reports say.

Stem Cell Science Can Proceed Ethically

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

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

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

Here are some headlines concerning early man and the ongoing struggle by humans to improve life.

Engineers Chase Animals

Inspired by the wisdom inherent in living organisms, inventors and engineers are finding bright ideas.

Stem Cell Wars Continue

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

The wonder of muscle inspires both awe at its design and opportunities for evolutionary storytelling.

New Biomimetics Projects

These recently-reported attempts to mimic nature show that the biomimetics revolution continues, with no end in sight.
