Heal the Blind with Stem Cells

June 30, 2010

Have you heard that some cases of corneal blindness can be cured by stem cells #– from the person’s own eyes? New Scientist recounted some recent successes for victims blinded in one eye by burns or acid. Stem cells taken from the limbus, a disk surrounding the iris, and transplanted onto the damaged cornea, were […]

The RNA Code: Pseudogenes Functional, Help Prevent Cancer

June 24, 2010

A surprising function has been discovered for a “pseudogene” – an apparently mutated copy of a regular gene that till recently was thought to be genetic junk. This pseudogene, reported in Nature today,1 not only has a function unrelated to the production of proteins, but a function that could save your life. It is part […]

Evolution Tries to Figure Out Dads

June 19, 2010

Why did evolution produce fathers? After male adult humans deliver their genetic component of the zygote, what are they good for? This is a subject in which the Darwinian and the Judeo-Christian concepts of fatherhood begin at opposite poles. But they have to converge on the practical observations of what fathers do best when they […]

Get a Life with Nature

June 6, 2010

Feeling bored, low on energy, exhausted? Don’t reach for a cup of coffee. Get out into nature. Researchers at the University of Rochester ran some controlled experiments on college students and found that those who spent a little time outdoors felt happier and more energetic. “Spending time in nature makes people feel more alive,” the […]

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

June 4, 2010

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 […]

Fooling Around with OOL

May 31, 2010

Origin of Life (OOL) research is one of those areas in science where one doesn’t have to make any real progress, as long as he or she looks busy. Anything the scientist says, no matter how speculative, or even foolish, is likely to be taken seriously, because the alternative – creation – has already been […]

Stem Cells: Hope, Politics, Charity, and Clarity

May 30, 2010

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 […]

Could This Protein Delay Aging?

May 24, 2010

It’s called Heat Shock Protein 10. It responds to stress, and might just slow the aging process, scientists are finding. Science Daily reported, “Scientists in the UK and the U.S. have discovered that a protein which responds to stress can halt the degeneration of muscle mass caused during the body’s aging process.” Why […]

Southpaw Explanations Out of Left Field

April 30, 2010

All proteins are left handed. Some humans are left handed. Can evolution explain that? Evolutionists are never known to be at a loss for words when asked to explain anything, provided they are allowed liberal use of the word perhaps. A new projection theme for the first left-handed amino acids that comprise proteins […]

Clock Gene Same in Humans and Birds

April 29, 2010

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 […]

To Sleep, To Dream: To Dream, Perchance, to Learn

April 25, 2010

When you have learned a complex task, take a nap and dream about it. A new study shows that dreaming helps consolidate the memory in your mind and helps you perform the task better next time around. Science Daily reported on research by scientists at Beth Israel Deaconess Medical Center. They tested 99 […]

Blood Clotting Fibers May Lead to Better Networks

April 22, 2010

We all know that blood clotting has kept us alive many times. We would never have survived childhood scrapes and cuts had it not been for a cascade of responses in blood that builds a network of fibers quickly upon which a scab of tissue stops the flow of blood and begins repairs. That first […]

Human Genome “Infinitely More Complex” Than Expected

April 5, 2010

Ten years after the Human Genome Project was completed, now we know: biology is “orders of magnitude” more complicated than scientists expected.

Man Will Never Fly (to the Stars)

March 13, 2010

It’s risky to say “never” in science. The Man Will Never Fly Society had a short life. However, an article on Space.com makes it seem a safe bet that, Star Trek notwithstanding, warp-speed flights to the stars are out of the question for humans. “Warp speed will kill you,” the article announced; why? Because interstellar […]
