Whenever a scientist says something like, don’t worry our new experiment could never get out of the lab, or don’t worry the miniature black hole we are going to generate couldn’t possibly swallow up the entire planet, I tend to get a little worried.… Read More “Scientist Says "Never in Our Imagination Could This Happen." Famous Last Words?”
A new finding has discovered that the human genome may be highly networked. That is, genes do not operate in isolation, but rather they are networked together in a far more complex ecosystem than previously thought. It may be impossible to separate one gene from another in fact.… Read More “Networked Genome — New Finding Shatters Current Thinking”
There are thousands of promising drugs for treating diseases that are simply not getting studied or brought to market because they are derived from natural or common substances that can’t be patented. The dirty little secret of the pharma business is that even a miracle cure for cancer won’t be invested in if it can’t be defended as a proprietary product.… Read More “Open-Source Medicine”
Japanese scientists have developed a technique that can encode 100-bit messages into the DNA of common bacteria. The bacteria replicate and pass the message down from generation to generation for at least thousands of years. Because there are millions or more copies of the message it can survive gradual degradation or mutuations (so they claim).… Read More “Scientists Encode Message into Bacterial DNA”
This is a somewhat scary article about the hazards of genetically modified grapes and the wines they may be used to produce. The article is from the extreme anti-genetic-engineering perspective, and so I don’t know how balanced it is or what the opposing view might say.… Read More “GM Grapes and Toxic Wines”
Scientists have discovered a dramatic variation in the genetic
make-up of humans that could lead to a fundamental reappraisal of what
causes incurable diseases and could provide a greater understanding of
mankind.
The discovery has astonished scientists studying the human genome – the
genetic recipe of man.… Read More “Major Breakthrough Revolutionizes Genetics”
… Read More “Playing Proteins as Songs Helps Researchers Hear Patterns”All living things are made up of proteins. Each protein is a string of
amino acids. There are 20 different amino acids, and each protein can
consist of dozens to thousands of them.Scientists write down these amino acid sequences as series of
text letters.
Researchers in South Korea may have discovered a new cure for cancer — a genetically engineered form of a virus that causes colds. By injecting this in animals with cancer it kills 90% of all cancer cells within 60 days, with no other side-effects.
This article discusses RNA interference (RNAi), a technique which can selectively turn genes off, which is currently in the early stages of testing. It shows promise for treating a broad spectrum of diseases.
Here’s an interesting video about a village in India where men have been stricken for over a decade with a disease that causes them to age much faster. Nobody knows what is causing this. Men in their 30’s appear to be 80.… Read More “A Village Where Aging is Sped Up”
It has just come out that supplies of rice in the USA have been contaminated with a gene that was not approved for human consumption.
A major new discovery about the structure of DNA molecules has been announced. Researchers have found there is a pattern to the organization of nucleosomes in DNA, which may explain why certain parts of the molecule are accessible or inaccessible to transcription.… Read More “New Level of Order Discovered in DNA”
South Korean researchers have synthesized a molecule that seems to not only stop, but also reverse, the built-in aging functions of cells.
… Read More “Anti-Aging Molecule Discovered”A team of South Korean scientists on Sunday
claimed to have created a “cellular fountain of youth,’’ or a small
molecule, which enables human cells to avoid aging and dying.
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.
The Edge has published mini-essays by 119 "big thinkers" on their "most dangerous ideas" — fun reading.
… Read More “Big Thinkers' Most Dangerous Ideas”The history of science is replete with discoveries
that were considered socially, morally, or emotionally
dangerous in their time; the Copernican and
Darwinian revolutions are the most obvious.
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”
From Boing Boing today:

says 20 percent of human genes have been patented in the United States:The study (…) is the first time that a detailed map has been
created to match patents to specific physical locations on the human genome.
A cutting-edge research program is injecting human brain cells into monkey brains, to investigate whether this causes their brains to become more "human." This poses a potential ethical challenge: If the monkeys do become more human, would they be considered "human subjects" and be protected by ethical guidelines governing research onto humans?… Read More “Human-Brained Monkeys Pose Ethical Challenge”
Several recent articles discuss the discovery of insects that clone themselves:

America but has spread into the US and beyond, has opted for a unique
stand-off in the battle of the sexes.
In an amazing new research finding, it turns out that a substantial amount of the so-called "junk DNA" in humans and other vertebrates is the same and has remained unchanged for 600 to 700 million years. Not only that but it turns out that at least some of the base pairs in this set have been found to regulate genes in other parts of the genome.… Read More “New Discovery – All Vertebrates Share Certain "Junk DNA" Segments”
… Read More “Hackers Crack Junk DNA?”A group
of researchers working at the Human Genome Project will be
announcing soon that they made an astonishing scientific
discovery: They believe so-called non-coding sequences (97%) in
human DNA is no less than genetic code of an unknown
extraterrestrial life form.
Here is a thought-provoking article that discusses several possible directions for the future evoloution of the human species. It includes comments by Richard Dawkins, as well as several scenarios with pictures of what humans might look like in the distant future.
