- A Leaf from Far, Far Away and Very, Very Close (Florida State University - Davidson)
"View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons."
- -Genetic Link to Autism Found (Wall Street Journal)
"Scientists say that roughly 20% of autism cases can be linked to known genetic abnormalities, and many more may be discovered."
"Last week, for example, researchers reported that an experimental drug, arbaclofen, reduced social withdrawal and challenging behaviors in children and adults with Fragile X syndrome, the single most common genetic cause of autism."
"Researchers at the University of Melbourne, Australia, have developed a test that looks for 237 genetic markers called single-nucleotide polymorphisms (SNPs). Some are thought to raise the risk of autism; others seem to protect against it. The test correctly predicted autism with more than 70% accuracy in people of Central European descent, but only 54% in those of Chinese descent, according to a study in the journal Molecular Psychiatry this month."
- -Link Found Between Religion and Genes (ABC News)
"Recent studies with twins show that while environmental factors play a big part in determining a person's degree of faith early in life, later on genetics take over and become a dominant factor as people make the transition into adulthood and either strengthen or reduce the role of religion in their lives."
- Archbishop Tutu's Genome Examined (Time.com)
"Archbishop Desmond Tutu dedicated his life to the promotion of equality. Now a new study of his genetic makeup has helped scientists understand how different human beings are — at least genetically."
" 'It is exciting that science is finding evidence of genetic diversity among groups of people as well as among individuals, and this discovery should be embraced, not feared,' he said. 'It would be disastrous if scientists were to ignore the diversity of the human race because this is the greatest asset of humanity.' "
- Bacteria Adapt by Swapping Genes (Scientific American)
"Bacteria, like all organisms, have to make a living in an ever changing world. They face shifting climates, varying food supplies and--horror of horrors--antibiotics. How do they adapt? According to the results of a new study, simply by copying the successful innovations of their relatives."
"The team revealed that the bacteria do this by using a process known as horizontal gene transfer, in which a cell passes genetic information to another cell that is not its offspring."

- Genes Help Us Select Friends (MSNBC News)
"A forthcoming study in the Archives of Psychiatry says that we can add how we choose our friends to the growing list of traits strongly influenced by genetic factors. A team of Virginia Commonwealth University researchers found that genes, alongside environment, strongly influence who we choose as friends. The researchers studied the peer groups of approximately 1,800 male twins, having each subject describe the level of social deviance among their friends, such as how many of their friends got drunk, used or sold drugs, or damaged property. The research showed that an individual's selection of friends--whether they chose to socialize with fewer or more socially deviant peers--was shaped by genetic factors." 08-07

- Genetic and Fossil Records Tell Different Stories on Origins of Humans (New York Times)
"After decades of digging, paleoanthropologists looking for fossilized human bones have established a reasonably clear picture: Modern humans arose in Africa some 200,000 years ago and all archaic species of humans then disappeared, surviving only outside Africa, as did the Neanderthals in Europe. Geneticists studying DNA now say that, to the contrary, a previously unknown archaic species of human, a cousin of the Neanderthals, may have lingered in Africa until perhaps 25,000 years ago, coexisting with the modern humans and on occasion interbreeding with them." 07-12

- Love and Chemistry (PBS.org)
"Young, a researcher at the Yerkes National Primate Research Center at Emory University in Atlanta, studies the neurobiology that underlies pair bonds -- what nonscientists might call love."
"In an essay in the journal Nature last month, he laid out evidence that scientists may soon be able to tie the emotion 'love' to a biochemical chain of events, and might someday even be able to develop drugs that enhance social bonding -- in much the same way that pharmaceuticals today can help regulate emotions like anxiety and depression."
"In a study published in September in the Proceedings of the National Academies of Science, Walum studied a version of the AVPR1A gene that codes for vasopressin receptors in men. He studied more than 1,000 Swedish men, and found that men who carried a particular variant of the gene were less likely to be married than men without the variant, were more likely to report a recent crisis in their marriage, and ranked lower on a scale of partner bonding that asked questions such as 'how often do you kiss your mate?' "
"Now, Walum and his colleagues are studying whether there are similar relationships between oxytocin receptors and pair bonding in women -- a more difficult study, he says, because there are no genes with as straightforward a relationship to oxytocin receptors as the AVPR1A gene has to vasopressin receptors in males." 02-09

- New Theory Rejects Single-Ancestor Doctrine (Scientific American)
"Instead of one universal evolutionary tree, picture a three-trunk stand sharing a communal root system. A new theory of cellular evolution published in the current issue of the Proceedings of the National Academy of Sciences rejects Charles Darwin’s Doctrine of Common Descent—the idea that all organisms are derived from a single primordial ancestor. Instead, Carl Woese of the University of Illinois-Champaign proposes that the three cell types that comprise life on earth arose from three forms of proto cells that swam together in a dense genetic soup, freely sharing their DNA."
"Indeed, such DNA swapping was the driving force in the evolution of unicellular organisms, Woese argues. Biologists have traditionally credited this so-called horizontal gene transfer with just a minor role in cellular evolution. But Woese asserts that only by sharing their genes—or evolutionary inventions, as he calls them—could simple cellular organizations have given rise to more complex cell designs. In the beginning, he says, primitive cells 'did not have stable genealogical records.' But eventually, these lines—including the three that spawned all extant life forms—reached what Woese terms the "Darwinian threshold," the point at which a lineage matures to genetic stability. Here the cellular organization became fixed, leading to a traceable cell line via reproduction. 'Crossing a Darwinian threshold leads to a more solidified, organized cellular design,' he explains." 12-05
- Scientists Create First Artificial Genome (ABC News)
"It may not quite be 'Frankenstein,' but for the first time scientists have created an organism controlled by completely manmade DNA."
"Using the tools of synthetic biology, scientists from the J. Craig Venter Institute installed a completely artificial genome inside a host cell without DNA. Like the bolt of lightening that awakened Frankenstein, the new genome invigorated the host cell, which began to grow and reproduce, albeit with a few problems." 05-10

- Unusual Gene Causes Blond Hair (New York Times)
"In the Solomon Islands, about 10 percent of the dark-skinned indigenous people have strikingly blond hair. Some islanders theorize that the coloring could be a result of excess sun exposure, or a diet rich in fish. Another explanation is that the blondness was inherited from distant ancestors — European traders and explorers who came to the islands."
"But that’s not the case, researchers now report. The gene variant responsible for blond hair in the islanders is distinctly different from the gene that causes blond hair in Europeans." 05-12
- Worms Move Up on the Tree of Life (CBS News)
"With the new study results, the researchers say the two worm groups constitute an entirely new division of life, or phylum, which they name the xenacoelomorpha. This phylum would join the three known phyla of deuterostomes: vertebrates (animals with a backbone, including humans); echinoderms (such as starfish), and hemichordates (such as acorn worms)."
"Being such simple creatures and yet still mixing and mingling on the family tree with us complex creatures suggests these marine worms were once complex themselves, Telford said."
