Ripeness Sticker – Brilliant

A University of Arizona professor has invented a ripeness sticker that shows how ripe a piece of fruit is. Why didn’t I think of this!!! This is a simple, brilliant idea. It’s right up there with the blue-tip match. The University of Arizona is going to make a lot of money on this.… Read More “Ripeness Sticker – Brilliant”

Electric Currents Heal Wounds

150 years ago, German physiologist Emil Du Bois-Reymond discovered that electric currents could speed up the healing of flesh wounds. But his research has been ignored ever since. Until now…

Now Josef Penninger of the Austrian Institute of Molecular
Biotechnology in Vienna and Min Zhao of the University of Aberdeen, UK,
have demonstrated that natural electric fields and currents in tissue
play a vital role in orchestrating the wound-healing process by
attracting repair cells to damaged areas
.

Fatherhood Boosts Male Brains

New research has shown that fatherhood brings about dramatic enhancements in male brains. Although the researchers don’t suggest it, this effect may be nature’s way of counteracting the dramatic decrease in male brain function that occurs in proportion to the number of times they get laid in a given week (Note: this particular malady was brought to national attention on the popular TV show Seinfeld).

New Level of Order Discovered in DNA

Electronic Smog

Are you living in a cloud of electronic smog? New research has shown that fields from electrical wiring and devices in the home and office should be considered to be a form of pollution. Recent studies are finding that many cancers and other diseases may be directly related to exposure to these electrical fields.

Moderate Drinking Turns out to Not be So Healthy After All

A new study has found a fatal flaw in past studies that claimed moderated drinking is good for your health. It seems the past studies compared moderate drinkers to abstainers, and found the moderate drinkers were more healthy. Unfortunately what they neglected to consider was the fact that many of their abstainers were abstaining because they had other health problems or were frail and elderly and on medications that interacted with alchohol.… Read More “Moderate Drinking Turns out to Not be So Healthy After All”

Widely Used Food Packaging Material Related to Surge in Prostate Cancers

More evidence that many synthetic food and beverage packaging materials are unsafe:

A CHEMICAL used to make food wrapping and line tin cans could be the
cause of surging prostate cancer rates in men, says a study.

Bisphenol A is widely used in the food industry to make
polycarbonate drinks bottles and the resins used to line tin cans, even
though it is known to leach into food and has long been suspected of
disrupting human sex hormones.

Study Discovers Whale Song Syntax

New research into the mathematical properties of whale songs reveals that they have a complex language:

The songs of the humpback whale are among the most complex in the
animal kingdom. Researchers have now mathematically confirmed that
whales have their own syntax that uses sound units to build phrases
that can be combined to form songs that last for hours.

Neuro-Chips

Researchers continue to make progress in fusing living neurons with computer chips:

The
line between living organisms and machines has just become a whole lot
blurrier. European researchers have developed "neuro-chips" in which
living brain cells and silicon circuits are coupled together.

Why Do Some Bacteria Contain Magnetic Crystals?

It was previously thought that some types of bacteria carry around magnetic crystals in order to orient themselves. But a recent study has found that in fact this does not seem to be the case — so why do they carry magnetic crystals?… Read More “Why Do Some Bacteria Contain Magnetic Crystals?”

Scientists Solve Flu Virus Replication Mystery

In a big step for medicine, scientists have figured out how the flu virus replicates — including the bird flu —  inside cells. This opens up new pathways for developing drugs to fight all strains of the flu.

Quantum Evolution — A Radical Theory

The theory of quantum evolution is a radical new take on how mutations
in DNA occur. Basically the theory postulates that DNA molecules are in
fact macroscopic quantum objects that undergo quantum interference. It
is spearheaded by Johnjoe McFadden, a professor in the UK and makes for an interesting read.… Read More “Quantum Evolution — A Radical Theory”

Brains Scans Show Unexpected Effects of Accupuncture

Aspartame (Nutrasweet) Proved to Cause Cancer at Human Levels of Ingestion

A recent study has found that human-level dosages of aspartame (the artificial sweetener formerly known as Nutrasweet and now cleverly disguised by new, obscure trade-names) causes stastitically significant increases in the occurrance of multiple forms of cancer. In other words, don’t drink diet colas that include aspartame, don’t chew sugar-free gum, and when you see "sugar-free" on food, beware.… Read More “Aspartame (Nutrasweet) Proved to Cause Cancer at Human Levels of Ingestion”

New Study: Human Hands, Feet and Foreheads Emit Light

Now this is really interesting! New research has found that certain parts of the body emit measurable numbers of photons. This may open up new diagnostic techniques. But that’s just the beginning. Spiritual healers from many different faiths have long said that they experience light coming from their hands, and can feel (and even see) energy from the hands, feet and heads of other people.… Read More “New Study: Human Hands, Feet and Foreheads Emit Light”

Using DNA to Send Messages into the Distant Future

This article discusses recent research into encoding short 100 word messages into the DNA of living organisms. The error-correcting characteristics of DNA enable such messages to be passed down without degrading across generations. By embedding short messages into hardy organisms such as particular strains of bacteria, it may be possible to preserve information over longer timeframes than by using any other known storage media.… Read More “Using DNA to Send Messages into the Distant Future”
