Plants Have Memories

June 09, 2010 — Have you ever noticed how plants have an uncanny ability to know, without eyes or brains, when the time has come to bloom?  Even when spring comes early or late in some years, they sense the right time, and out come the flowers.  This is even more remarkable when you consider […]

Your Nerves and Heart Depend on Cellular Pulleys, Latches and Switches

Biologists continue to peer closer and closer at cellular machines that work just like man-made ones, only at scales so tiny, they control individual atoms.  Of particular interest have been the gates in the membranes of cells that allow certain atoms in but keep others out.  A recent paper in Cell by an Australian team […]

Venter’s Synthetic Plagiarism Deflated by NY Times

How significant was Craig Venter’s achievement of a so-called synthetic genome?  Somewhat significant, but it pales in significance to creating life from scratch.  It was only like “peering over a fortress that is the mighty cell,” wrote Natalie Angier for the New York Times Monday, May 31.     The article was accompanied with a […]

Stem Cells: Hope, Politics, Charity, and Clarity

Those promising little cells that can differentiate into almost any tissue continue to make news – but they also continue to generate controversy.  Actually, only some of them generate controversy: the embryonic stem cells.  Not all of the articles about stem cells make that clear.  Defining life:  With the stroke of a pen, South Korea […]

Venter Group Plagiarizes Genetic Code

Is plagiarism a form of intelligent design?  We think of intelligent design in terms of God and creation, but in generic terms, I.D. only refers to purposeful, designed action by an agent – any agent, large or small, good or evil.  A planned murder, for instance, can be an evil form of intelligent design.  A […]

If Humans Build DNA Machines, Is It Intelligent Design?

Two teams have succeeded in building little robots that work on DNA tracks.  These resemble in many respects the machines that cells use to perform its functions on DNA.  No one denies that humans engineered their nanobots on purpose, but Darwinist scientists claim natural cellular machines evolved without purpose or design.  What’s the difference?   […]

Bacteria: Let’s Harness Those “Perfect Machines”

Ten Italian scientists have a novel idea.  They want to hitch up their wagons to bacteria and use them to power nanomachines.  It’s too much work to build such “perfect machines” from scratch, they said.  Why not just take advantage of what nature has already provided?     Their paper in PNAS1 is downright dreamy […]

Humans and Neanderthals Are One

If Neanderthals bred with modern humans, they are one and the same species.  That must be the case according to the most widely-accepted definition of a species: those who can breed and produce fertile offspring.  The news media are abuzz with Science magazine’s cover story this week, “The Neanderthal Genome.”1  Most anthropologists are now accepting […]

Can Darwin Be Rescued from a New Eye Discovery?

Scientists find waveguides and noise receptors built into the retina.

Breakthrough: Second Genetic Code Revealed

It’s sometimes difficult to assess the impact of a scientific paper when it is first published, but one that came out on the cover of Nature today has potential to equal the discovery of the genetic code.  The leading science journal reported the discovery of a second genetic code – the “code within the code” […]

Darwin’s Linux: Did Evolution Produce a Computer?

How is a cell like a computer?  Some Yale scientists asked that question, and embarked on a project to compare the genome of a lowly bacterium to a computer’s operating system.1.  Their work was published in PNAS.2  As with most analogies, some things were found to be similar, and some different – but in the […]

Scientist Sees Evolutionary Sense in Coordinated Complexity

An article on PhysOrg tells “A vertebrate story,” and a story it is: the more complex a phenomenon becomes, the more it makes evolutionary sense.     Portuguese scientists were studying the interaction of Hox genes with the development of the ribs in vertebrates.  You can imagine the control that these genes must have when […]

Clock Gene Same in Humans and Birds

Science Daily, this “not only sheds light on how our internal annual body clocks function but also shows a key link between birds and mammals that has been conserved over 300 million years.”     Mammals, including humans, have a hormone released by the pituitary gland that controls melatonin levels – known to affect the […]

New Theory on Evolution of Bat Flight

How did bats evolve the ability to fly?  Evolution helped them out by providing them with higher energy.  After all, “Flight is among the most energy-consuming activities” in the animal kingdom, said a team of Chinese and Canadian scientists reporting in PNAS,1 so it’s obvious that evolution must have provided the genes to get the […]

Update on Interplant Internet

One of the early “amazing” stories reported in these pages concerned the startling observation that plants use a kind of “email” system in their own interplant “internet” (see 07/13/2001).  What has been learned in the nine years since that story appeared?  Quite a lot, and another fascinating article about plant communication appeared this week in […]
