Let a thousand genomes bloom
Posted: Tuesday, January 22, 2008 9:18 AM by Alan Boyle

Genetic researchers in China, Britain and the United States are teaming up to unravel the full genetic code of at least 1,000 people around the world - an unprecedented scientific project that could cost tens of millions of dollars and eventually reveal the roots of hundreds of diseases.

"The 1000 Genomes Project will examine the human genome at a level of detail that no one has done before," Richard Durbin of Britain's Wellcome Trust Sanger Institute, who is the project consortium's co chair, said in today's announcement. "Such a project would have been unthinkable two years ago. Today, thanks to amazing strides in sequencing technology, bioinformatics and population genomics, it is now within our grasp."

The project will build on the foundation created for HapMap, a similarly international gene-decoding effort. HapMap charted genetic differences between various geographical populations by looking at variations in "letters" of genetic code, known as single nucleotide polymorphism or SNPs. This time, researchers will analyze the full volume of human genetic information - which runs to a length of 3 billion letters, or roughly the entire English-language content of Wikipedia.

Using HapMap and other genetic databases, researchers already have identified about 100 regions of the genome that are associated with increased risk for diseases ranging from cancer and diabetes to cystic fibrosis and Huntington's disease. But in order to track down exactly what goes wrong and how to fix it, researchers generally have to go through another circuitous round of genetic sequencing.

Taking the shortcut
The 1000 Genomes Project is aimed at providing a shortcut: The organizers of the effort figure that by mapping at least 1,000 full human genomes, they should be able to catalog the variants that appear in 1 percent or more of the global population across most of the genome. Within specific genes, the precision should be even better, catching variations down to the 0.5 percent level.

That would improve the sensitivity of disease discovery efforts by a factor of five for the full genome, and by a factor of 10 or more within gene regions, said Francis Collins, who headed the Human Genome Project and is now director of the federally funded National Human Genome Research Institute.

Once the project's database is filled out, researchers could use genome-wide association studies to narrow down an area that appeared to be associated with a disease. Then they could consult the catalog for the assorted variations within that region. Finally, they could run studies to figure out whether - and exactly how - particular variations contribute to the disease in question.

The data will be made freely available to researchers around the world, starting in 2011 or so, via the National Center for Biotechnology Information, the European Bioinformatics Institute and the Beijing Genomics Institute in Shenzhen.

Who's involved?
The first samples for the 1000 Genomes Project will be coming from specimens already collected for the HapMap project and the extended HapMap set. The DNA is not linked to personal medical data, but rather to ethnic/geographical populations: Yoruba in Nigeria, Japanese in Tokyo, Chinese in Beijing, Utah residents with northern European ancestry, Luhya and Maasai in Kenya, Toscani in Italy, Gujarat Indians in Houston, Chinese in metropolitan Denver, Mexican-Americans in Los Angeles and African-Americans in the Southwest.

The project is getting major support from the institutes headed by Durbin and Collins, as well as from the Beijing Genomics Institute. A variety of American institutes and universities will be working through the National Human Genome Research Institute's Large-Scale Sequencing Network - and more institutions may join the international consortium as time goes on.

Based on current rates, the cost of sequencing so many genomes would amount to at least $350 million, and perhaps more than $500 million. Earlier this month, Massachusetts-based Knome and the Beijing Genetics Institute announced that they were pairing up to do whole-genome sequencing for 20 people, with a price tag starting at $350,000 per genome. (You think that's expensive? BGI did the first Chinese personal genome last year for $1.3 million.)

Over the next three years, the 1000 Genomes Project is aiming to bring the cost down to a tenth of the current rate - for a total cost of between $30 million and $50 million - by employing new sequencing technologies with greater efficiency.

The road ahead
The first year of the international effort will be taken up with pilot projects, aimed at finding out which combination of low-resolution and high-resolution sequencing will work the best. Then, during the scheduled two-year production phase, researchers hope to churn out an average of 8.2 billion DNA bases per day - the equivalent of more than two full human genomes every 24 hours.

"When up and running at full speed, this project will generate more sequence in two days than was added to public databases for all of the past year," the University of Oxford's Gil McVean, one of the co-chairs of the consortium's analysis group, said in today's announcement.

Will the project hasten the day when your genome is an open book, revealing your predisposition to suffer deadly diseases - and perhaps to do dastardly deeds? The project's organizers say that they're deploying a phalanx of ethicists to guard against abuses, and that the privacy of genetic donors will be preserved. What do you think? Learn more about the project from the 1000 Genomes Web site, as well as this advance report from Nature, then weigh in with your comments below.

Update for 10:50 a.m ET: Nature's follow-up report says some scientists fear the project's goals are too ambitious for its budget and timeline. The report also quotes Knome's George Church as saying the project might not be ambitious enough, because the database won't link genetic variants directly with disease data. The project organizers held back from doing that due to privacy concerns - and also because they felt the medical applications were best left to follow-up studies. More food for thought...

Многу често слушаме за таа работа глобално затоплување по телевизии и интернет, а многу малку слушаме за анти-тезите на оваа теорија. Оваа теорија стана толку распространета, набиена во секоја пора од општеството, што понекогаш си мислам дека е малце исфорсирана, ако не и само наметнато размислување. На еден многу интересен сајт, HowStuffworks.com-самото име ви кажува се за сајтот-наидов на овие анти-тези за глобалното затоплување, кое некои научници го сметаат за нормална природна појава која била регистрирана низ исторјата повеќе пати. Наведуваат и други причини кои довеле до овој начин на размислување, навистина вреди да се прочита и да се погледне на овој проблем од друга страна.

Global Warming Skeptics' Arguments Since global warming became a major issue, climatology has become a hot-button scientific field. Weather stations throughout the world collect data to help scientists create computer models that help them track global climate change. Peter Essick/Aurora/Getty Images Weather stations, like this one, collect information throughout the world. But are some more reliable than others? These models form the basis of much of the IPCC's reports, which warn of global climate change. But climate skeptics take issue with this process. Some people simply don't believe that the Earth is undergoing a global warming trend or climate change. Others believe in global warming and climate change, but don't believe that people are responsible. The skeptics who don't believe in global warming at all are the ones who most vehemently attack weather data, the analysis of the climatologists and the predictions of the models. Anti-global warming skeptics say the placement of some weather stations in urban areas may produce inaccurate measurements. According to them, the data are being corrupted by the urban heat island, an effect produced by cities' transportation, large amounts of heat-absorbing asphalt, and high concentrations of carbon dioxide coming from the many homes and businesses in high-population areas. Global warming skeptics also believe the models used to predict Earth's future under global warming are unreliable. They feel that while the sun, clouds, gases, glaciers and oceans are responsible for weather, so, too, are other factors, including some we don't currently understand. According to global warming skeptics, computer models are merely a guess at what will happen on Earth in the future -- something climatologists don't deny -- and an arguably poor guess at that. After all, if we can't accurately predict the weather a week from now, how can we predict the global climate in 100 years? Others don't believe we're experiencing a global warming trend at all. The annual temperature between 1998 and 2007 actually decreased, despite the 4 percent increase in carbon dioxide in the atmosphere during that same period. They also point out that, while the Northern Hemisphere has warmed, the Southern Hemisphere has actually cooled. "Global warming was supposed to actually be global, not hemispheric," says skeptic -- and Executive Director of the Natural Resources Stewardship Project -- Tom Harris [source: Canada Free Press]. These same skeptics find fault in the historical data used to graph things like glacial loss and hurricane frequency. Although weather data, like temperature, have been actively collected since 1850, it wasn't until the relatively recent access to detailed weather satellite photography that scientists were able to see changes in the Greenland ice shelf that global warming believers say is in such danger. Skeptics ask: How can we know how long it's been receding? Perhaps the meteorological event most often used by global warming skeptics as a counterargument is the Medieval Warm Period. Around the 9th to 14th centuries, regions around the world experienced an increase in temperatures, similar to what we see today [source: National Oceanic and Atmospheric Administration]. Following this period, the Earth experienced a Little Ice Age where global temperatures cooled. It is conceivable that the Earth is currently experiencing something similar to this, skeptics say. Their point is, we simply don't know enough about long-term weather systems to say for certain one way or the other. The skeptics of human-caused (anthropogenic) global warming don't dismiss global warming outright, they just don't believe that human activity is responsible.

Start-Up Sells Solar Panels at Lower-Than-Usual Cost

SAN JOSE, Calif. — Nanosolar, a heavily financed Silicon Valley start-up whose backers include Google’s co-founders, plans to announce Tuesday that it has begun selling its innovative solar panels, which are made using a technique that is being held out as the future of solar power manufacturing.

The company, which has raised $150 million and built a 200,000-square-foot factory here, is developing a new manufacturing process that “prints” photovoltaic material on aluminum backing, a process the company says will reduce the manufacturing cost of the basic photovoltaic module by more than 80 percent.

Nanosolar, which recently hired a top manufacturing executive from I.B.M., said that it had orders for its first 18 months of manufacturing capacity. The photovoltaic panels will be made in Silicon Valley and in a second plant in Germany.

While many photovoltaic start-up companies are concentrating on increasing the efficiency with which their systems convert sunlight, Nanosolar has focused on lowering the manufacturing cost. Its process is akin to a large printing press, rather than the usual semiconductor manufacturing techniques that deposit thin films on silicon wafers.

Nanosolar’s founder and chief executive, Martin Roscheisen, claims to be the first solar panel manufacturer to be able to profitably sell solar panels for less than $1 a watt. That is the price at which solar energy becomes less expensive than coal.

“With a $1-per-watt panel,” he said, “it is possible to build $2-per-watt systems.”

According to the Energy Department, building a new coal plant costs about $2.1 a watt, plus the cost of fuel and emissions, he said.

The first Nanosolar panels are destined for a one-megawatt solar plant to be installed in Germany on a former landfill owned by a waste management company. The plant, being developed by Beck Energy, is expected to initially supply electrical power for about 400 homes.

The company chose to build its plant in southern San Jose, news that was cheered by local development officials. Much of the microelectronics industry created here has moved to Asia and new factories are a rare commodity in Silicon Valley.
