Gobekli Tepe: What Mean These Ancient Stones?
March 10, 2009
Imagine stone carvings and monuments whose age make the pyramids and Stonehenge look like artifacts of modern history. Such monuments exist on a hill in Turkey at a site called Gobekli Tepe. Squared-off limestone blocks stacked like the letter T, arranged in circles, with ornate animal carvings on them, have been baffling archaeologists for the […]

Elect Obama, Get Embryonic Stem Cells
March 8, 2009
President Obama is about to fulfill of his campaign promises: lifting restrictions on creating new embryonic stem cell lines (see Fox News).  The question now is, are they really needed?  They have yet to show any successes, while adult stem cells are enjoying an accelerating boom of amazing discoveries that could provide hope for some […]

Adult Stem Cells, +2; Embryonic Stem Cells, -1
February 23, 2009
Two more successes were chalked up for adult stem cell therapies recently.  Science Daily said that sufferers from Crohn’s disease may have a new treatment option by getting injections of their own bone marrow stem cells.  This “now constitutes a treatment option to cure an intestinal disease that sometimes does not successfully respond to drugs […]

Assassins Roam Our Highways
February 22, 2009
Slinking surreptitiously through our blood streams, the assassins prowl about, looking for their targets.  These are not terrorists or vigilantes.  They have a license to kill.  Be glad they are there; they have saved your life many times.  They are called natural killer cells.     PhysOrg reported on work going on at Howard Hughes […]

Language Is Not a Simple Genetic Matter
February 18, 2009
It sounds so simple.  The title on an article in PhysOrg announced, in Kipling Just-So Story Format, “How gorilla gestures point to evolution of human language.”  Because gorillas have an extensive repertoire of over 100 gestures, human conversation was only a matter of evolutionary time.  Is this mere storytelling, or do such explanations have scientific […]

Obama and Stem Cells: Hope Chest or Pandora’s Box?
January 31, 2009
Any day now, as he promised, President Obama will likely lift funding restrictions on embryonic stem cell research imposed by former President Bush.  Bush had sought the council of leading scientists and ethicists before making his decision.  Obama, by contrast, will be yielding to the opinions of the scientific societies who have clamored for years […]

Immune System Has a Code, Language and Memory
January 24, 2009
“Decoding the language of memory cells” is the title of an article in Science Daily.  A researcher at the University of the School of Medicine is using the concepts of codes, language and memory to understand the way T-cells “remember” a pathogen to prevent later infections.  “We are currently figuring out which signals are important […]

Exploring the Malleability of Evolutionary Explanation
January 23, 2009
Is evolutionary theory just a very malleable and ductile idea, able to adapt to changing observations, or should it be described as a strong theory, powerful in its explanatory breadth?

Biology Now Includes Fluid Dynamic Construction
January 13, 2009
There’s an old legend that Tibetan monks built a wall by levitating heavy stones with sound by beating their drums and gongs.  Something not quite so fantastic but still amazing is done by cells in the embryo.  Scientists have filmed zebrafish embryos using beating cilia to build little stone structures that they use for balance.

Send the Brat Outside
January 5, 2009
Problem teens get dramatically cured by wilderness adventures, researchers at the University of Essex found.  Science Daily reported that young offenders came back from their hikes and sailing trips with increased self-confidence, teamwork, trust, a sense of belonging, and a desire to cooperate and take responsibility for their future.     Youths described initially as […]

Your Brain Decides Best Unconsciously
January 4, 2009
A report on Science Daily claims your subconscious brain makes the best decisions possible.  This is based on work by cognitive neuroscientists at the University of Rochester.  Alex Pouget believes the brain is hard-wired to make optimal decisions – when we are not consciously thinking about them. Pouget has been demonstrating for years that certain […]

Plants Heal Humans and Vice Versa
December 29, 2008
Flowers in your hospital room do actually make you heal faster.  A study by Kansas State researchers reported by PhysOrg found that more patients recovered from abdominal surgery faster with flowers in the room.  It may be due to more than the psychological benefit of enjoying their colors, fragrances and the get-well wishes behind them: […]

Cilium Likened to GPS
December 27, 2008
A story on Science Daily says that the primary cilium, a protrusion on most human cells that looks like an antenna, acts like a GPS system.  They “orient cells to move in the right direction and at the speed needed to heal wounds, much like a Global Positioning System helps ships navigate to their destinations.” […]

Who Wants Embryonic Stem Cells?
December 17, 2008
Amazing treatments continue to spring forth from adult stem cells – the stem cells with no ethical qualms attached.  With adult stem cells easy to obtain doing so much good, why would anyone want embryonic stem cells (the stem cells with ethical qualms attached), when no usable treatments have yet been found? Here are some […]

Nature Plagiarizes Behe’s Mousetrap
December 9, 2008
The prevention of genomic instability – and cancer – can be attributed to a “complex mousetrap” mechanism, said Robert M. Brosh, Jr (Laboratory of Molecular Gerontology, NIH) in Nature.1  This not-so-subtle reference to Michael Behe’s irreducibly complex system described in Darwin’s Black Box even has a mousetrap illustration with the following caption: The BLM protein […]
