    It's not often that cultural and religious persecution makes countries more diverse, but the Spanish Inquisition might have done just that. One in five Spaniards and Portuguese has a Jewish ancestor, while a tenth of Iberians boast North African ancestors, finds new research. This melting pot probably occurred after centuries of coexistence and tolerance among Muslims, Jews and Christians ended in 1492, when Catholic monarchs converted or expelled the Islamic population, called Moriscos. Sephardic Jews, whose Iberian roots extend to the first century AD, received much the same treatment. "They were given a choice: convert, go, or die," says Mark...

    MADRID (Reuters) – From the 15th century on, Spain's Jews were mostly expelled or forced to convert, but today some 20 percent of Spanish genes can be traced to Sephardic Jews, a study has found. A report in the American Journal of Human Genetics says almost a fifth of Spaniards' genes are of Sephardic Jewish origin and another 11 percent can be traced to North Africa. "The genetic composition of the current population is the legacy of our diverse cultural and religious past," one of the report's authors, Francesc Calafell, from the evolutionary biology faculty at Pompeu Fabra University in...

    Berlin doctor has reportedly cured a leukemia patient of the deadly AIDS virus, German daily Die Welt reported on Wednesday. For two years now, Dr. Gero Hütter has found no trace of the virus in the 42-year-old American living Berlin, whom he has treated for leukemia at the city’s Charité hospital. The man is AIDS-free despite the fact that he stopped taking his medication for AIDS after the treatment, the paper reported, calling the development a “sensation.”

It was greeted with euphoric proclamations that Palestinians and Jews are "brothers." A...

    Eight years ago, I published an article in these pages called "Wandering Jews—and Their Genes" (September 2000). At the time I was working on a book about a Tibeto-Burmese ethnic group in the northeast Indian states of Mizoram and Manipur, many of whose members believe that they descend from the biblical tribe of Manasseh, and about a group of Judaizers among them known as the B'nei Menashe, over a thousand of whom live today in Israel as converts to Judaism. This led me to an interest in Jewish historical genetics, then a new discipline. Historical genetics itself was still a...

    The same gene that affects a rodent's ability to mate for life may affect human marriages, Swedish and U.S. researchers reported on Tuesday. Men carrying a common variation of gene involved in brain signaling were more likely to be in unhappy marriages than men with the other version, the team at the Karolinska Institute found. Although they are not sure what the genetic changes do to a man's behavior, some other research suggests it has to do with the ability to communicate and empathize, the team reported in the Proceedings of the National Academy of Sciences.

    When it comes to memory it is clear that men and women are simply not on the same wavelength. While men may fail to match a woman's ability to remember the date of an anniversary, they are better at storing a seemingly endless cache of facts and figures. Scientists believe they have now uncovered the reason for this difference between the sexes – they make the memories in different ways.

    If snakes strike terror in your toddler’s heart, he might still grow to be brave. A tendency toward fearfulness does have genetic underpinnings, but those shift several times as children become adults, a study has found. The worries of adolescents differ from those of young children — fear of the dark gives way to squeamishness about blood in a well-documented developmental progression. Now, psychiatrist Kenneth Kendler of the Medical College of Virginia in Richmond and his colleagues have found that the genetic factors that leave a person prone to fear also shift during development. To tease apart the effect of...

Researchers found that among Ashkenazi Jews, those who survived past age 95 were much more likely than their peers to possess one of two similar mutations in the gene for insulinlike growth factor 1 receptor (IGF1R). The mutations seem to make cells less responsive than normal to insulinlike growth factor 1 (IGF1), a key growth hormone secreted by the liver. In past studies, IGF1 disruption increased the life...

    The genetic information of organisms--as varied as goldfish and geraniums--is widely available to the global public. So are the biologic codes for many viruses, such as variola (which causes smallpox) and poliovirus. The advance of biological technologies that allow for the construction of specific genetic sequences raises the harrowing possibility that someone, somewhere would use available genetic information to unleash a biological attack. The quandary facing scientists in the life sciences is similar to the issues that confronted scientists at the dawn of the nuclear age: Can potentially dangerous knowledge be made secret? Or should it be kept widely available?...

    Monsanto is developing genetically modified plants that use RNA interference to kill the insects that eat them. Researchers have created plants that kill insects by disrupting their gene expression. The crops, which initiate a gene-silencing response called RNA interference, are a step beyond existing genetically modified crops that produce toxic proteins. Because the new crops target particular genes in particular insects, some researchers suggest that they will be safer and less likely to have unintended effects than other genetically modified plants. Others warn that it is too early to make such predictions and that the plants should be carefully tested...

"This landmark will be a very important philosophical step in the history of our species. We are going from reading our genetic code to the ability to write it. That gives us the hypothetical ability to do things never contemplated before," sources reported on Saturday, quoting Venter as saying. He is expected to announce the discovery -- a feat of bio-engineering never previously achieved -- within weeks. According...

    Source: Massachusetts Institute Of Technology Date: September 11, 2007 New Method Can Reveal Ancestry Of All Genes Across Many Different Genomes Science Daily — The wheels of evolution turn on genetic innovation -- new genes with new functions appear, allowing organisms to grow and adapt in new ways. But deciphering the history of how and when various genes appeared, for any organism, has been a difficult and largely intractable task.

    A British pro-life group warns that a new type of embryo research, likely to be approved this week by a U.K. government panel, undermines human dignity. Britain's Human Fertilization and Embryology Authority is expected to give a green light this week to U.K. laboratories seeking to create the first animal-human embryos for medical research using eggs taken from dead cows. British scientists want to use the hybrid embryos in order to research genetic diseases. Anthony Ozimic, political secretary for the Society for the Protection of Unborn Children, opposes the embryo-destructive research. He says that an "a-nucleated" cow egg will only...
  • Smoking stays in your genes after you quit - Cigarette habit may leave a molecular mark.

The results could provide a molecular explanation for the continued increased risk of lung cancer and other pulmonary ailments among former smokers. When smokers quit, their bodies gradually begin to undo the damage cigarettes have wrought. But contrary to popular belief, not all of the body's systems make a full recovery. Although the risk of...

    Norwegian arhaeologists are puzzled by a find which indicates an Inca Indian died and was buried in the Oestfold city of Sarpsborg 1000 years ago. The remains of two elderly men and a baby were discovered during work in a garden, and one of the skulls indicates that the man was an Inca Indian. There is a genetic flaw in the neck, which is believed to be limited to the Incas in Peru, says archaeologist Mona Beate Buckholm. The Norway Post suggests that maybe the Vikings travelled even more widely than hitherto believed? Why could not the Viking settlers in...

    A dramatic genetic breakthrough has paved the way for potential new treatments of seven common diseases that could help more than 20 million people. The largest ever study of its kind has found 10 new genes linked to seven of the most common ailments: heart disease, rheumatoid arthritis, high blood pressure, type 1 and type 2 diabetes, bipolar disorder and Crohn’s disease. Some 200 British scientists from 50 research groups collaborated to discover the genes after screening DNA from 17,000 people. Dr Mark Walport, Director of the Wellcome Trust, the UK’s largest medical research charity, was optimistic about the study’s...

    It was 1959. Jules Hirsch, a research physician at Rockefeller University, had gotten curious about weight loss in the obese. He was about to start a simple experiment that would change forever the way scientists think about fat. Obese people, he knew, had huge fat cells, stuffed with glistening yellow fat. What happened to those cells when people lost weight, he wondered. Did they shrink or did they go away? He decided to find out. It seemed straightforward. Dr. Hirsch found eight people who had been fat since childhood or adolescence and who agreed to live at the Rockefeller University...
  • Corals: More Complex Than You ?(Possess More Genes Than Humans)

    25 April 2007 Corals: More complex than you? The humble coral may possess as many genes – and possibly even more – than humans do. And remarkably, although it is very distant from humans in evolutionary terms, it has many of the immune system genes that protect people against disease. In fact, it is possible some of these were pioneered by corals. Corals are among the simplest animals in the world – yet they may possess a set of genes as large and complex as our own, says Professor David Miller of the ARC Centre of Excellence in Coral Reef...

    US to outlaw corporate prejudice based on genes 10:00 06 May 2007 From New Scientist Print Edition. Soon it will be illegal to deny US citizens jobs or insurance simply because they have an inherited illness, or a genetic predisposition to a particular disease. On 25 April, the House of Representatives voted 420 to 3 to pass the Genetic Information Nondiscrimination Act (GINA). The Senate is expected to endorse the act within a few weeks, which is also supported by President Bush. "I am so stunned by the majority," says Sharon Terry, president of the Genetic Alliance, a charity lobbying...
