More Reasons to Enjoy Creation Outdoors

June 17, 2007

Evidence keeps mounting that exercise is good for almost every body. It can prevent and alleviate many ailments. But isn’t that only natural? Low back pain: Laziness increases the risk of back pain, reported EurekAlert on work from Australia. Staying in bed shrinks muscles needed to support the back. So does prolonged inactivity at a […]

Could Germ Toxicity Be an Environmental Effect?

June 15, 2007

Listeria becomes nasty when starved of oxygen, reported EurekAlert. “Limiting oxygen produces bacteria up to 100 times more invasive than similar bacteria grown with ample oxygen supplies.” Could this imply that a world with different atmospheric or soil conditions could have been less prone to disease? Could the bacteria we fear most have been placid […]

Take a Walk in the Biodiversity Park

May 16, 2007

A walk in the park is good for your spirit. That much we already knew. Researchers at the University of Sheffield now claim, though, that the more biodiversity in the park, the better: “Dr Richard Fuller and colleagues from the University’s Department of Animal and Plant Sciences, and De Montfort University in Leicester, have been […]

More Optical Design in Eye Retina Than Seen Before

May 2, 2007

For decades, evolutionists have used the vertebrate retina as an example of poor design (dysteleology). They have mocked how any designer could have been so unintelligent as to get the wiring backwards – with the photoreceptors behind a jumble of light-scattering cells. Creationists have countered that despite the arrangement, it works well.1 Now, they may […]

Snot Serious: Artificial Nose Works Better with Mucus

April 30, 2007

What will they think of next? Designers of electronic noses cannot yet come close to the natural nose in sensitivity. But in trying to improve their devices, they tried another trick from nature: artificial boogers. Yes, believe it or snot, adding a layer of synthetic mucus “improved the performance of their electronic nose allowing it […]

Human Adaptation Can Be Rapid

April 25, 2007

How long does it take for humans to adapt to environmental changes? Some recent papers investigated this question. Paleface: If it is assumed that humans started out medium or dark-skinned, how long did it take for Europeans to lose much of that original pigment? An article in Science April 20 says maybe just 6,000 to […]

Dirt for Physical and Mental Health

April 11, 2007

Live Science has an article suggesting that exposure to dirt can improve your mood by boosting the immune system. This is an unexpected twist on the “hygiene hypothesis” that childhood exposure to dirt and animals helps innoculate the body to certain diseases (see 08/02/2006). Certain bacteria might not only boost the immune system, but also […]

Preprocessed Sound Produces Tone Map in the Brain

April 6, 2007

Most of us know that our ears involve three domains: the outer ear, the middle ear, and the inner ear. We learned in school how the eardrum transmits the sound to tiny bones that transmit it to fluid in the cochlea, which stimulates hair cells that send the impulses down the auditory nerve to the […]

Adult Stem Cells Form Heart Valve

April 4, 2007

The BBC News reported that part of a heart valve was grown from stem cells. The article did not state till halfway down the page that the feat was achieved with adult stem cells, not embryonic stem cells. Everybody knows that the big battle over stem cells revolves around the ethics of using human embryos […]

Lunar Dust Is Deadly

March 22, 2007

A significant fraction of lunar dust could pose deadly risks to future astronauts stationed on the moon, a BBC News report says. About 1-3% of moon dust particles are too small to be coughed up or removed by the cilia lining the respiratory tract. These would lodge in the lungs and become inflamed. As in […]

Questions to Ask a Reductionist Neurobiologist

March 21, 2007

Can the totality of the brain be described in terms of its neurons? Is consciousness an artifact of the movement of signals in the brain? Can the complexity of the brain be described in terms of its evolutionary history? Does the hardware define the software that runs on it? Gy�rgy Buzs�ki attempted to address these questions […]

Have Scientists Found the Secret of Aging?

March 17, 2007

There’s a tragic disease that speeds up aging. Known as progeria (Huntington-Gilford progeria syndrome, HGPS), it is caused by a single point mutation in exon 11 of the NMLA gene. Children afflicted with this disease look old beyond their years and often die at 13 of heart attack and stroke – essentially, of old age. […]

Why Our Voices Are Unique

March 15, 2007

We can usually recognize friends and acquaintances by their voices. If we all have the same hardware, though, how is this possible? The answer is in the vortex. Sounds sci-fi, but researchers at the University of Cincinnati used knowledge of jet engines to explore the possibility that vortices may help solve the mysteries of the […]

Music Can Make You Smarter

March 12, 2007

Musical training in childhood can help one develop better language processing skills, reports a news item on EurekAlert. Scientists at Northwestern University found that English-speaking adults who had musical training were better able to track intonations of Chinese tonal words than those who did not have such training. The study contradicted an evolutionary […]

Skin Includes Built-In Damage Protection

March 11, 2007

Ultraviolet radiation that tans skin can also cause skin cancer, right? Right, but the skin also produces a cancer fighter to come to the rescue, reported EurekAlert. Scientists at the Dana-Farber cancer institute detected a known cancer fighter named p53 that is produced right under the skin. Their results, published in Cell (see summary on […]
