In other words, we've invested so much, why walk away now? But it's a logical error, known in social science as the dreaded sunk costs fallacy.
the imaging technique utilizes a broad-spectrum light source and a spectral interferometer to obtain high-resolution, reconstructed images from the optical signals based on an understanding of the physics of light-scattering within the sample.
A comprehensive new MIT-led study of the potential for geothermal energy within the United States has found that mining the huge amounts of heat that reside as stored thermal energy in the Earth's hard rock crust could supply a substantial portion of the electricity the United States will need in the future, probably at competitive prices and with minimal environmental impact. An 18-member panel led by MIT prepared the 400-plus page study, titled "The Future of Geothermal Energy." Sponsored by the U.S. Department of Energy, it is the first study in some 30 years to take a new look at geothermal, an energy resource that has been largely ignored.
University of South Florida researchers report that a novel needle-free vaccine approach is effective and safe in clearing brain-damaging plaques from a mouse model of Alzheimer's disease. The transdermal, or across the skin, vaccination, may offer a simpler way of preventing or treating the devastating neurodegenerative disease with less likelihood of adverse immune reactions.
Flash drives are getting smaller and smaller, and at the same time their capacity keeps getting bigger and bigger. All of this means the chances of losing your flash drive, and of that loss being disastrous, keeps rising.
Analysis of the Development, Production and Operating costs suggests that the average ticket price would be comparable to an existing Business class ticket. Therefore in principle the A2 vehicle could capture all of the current business and first class traffic due to the greatly reduced journey time of 4.6 hours compared to the current 22 hours. This estimate assumes hydrogen fuel derived from water electrolysis whereas the ticket price would roughly halve if the hydrogen is produced by steam reforming. Also the analysis assumes no hydrogen subsidy, however in reality it is likely that the first generation of hydrogen fuelled aircraft would be subsidised to promote the switch to a more environmentally friendly fuel.
This is another of the consequences of widespread pleiotropy -- genes that have important effects early in development may continue to be important in restricted tissues later in life. By being scored in a functional category related to these later functions, the earlier functions of the gene may be missed in the functional analysis. Screening gene expression at multiple times helps to catch these temporally sensitive functions.Bloggposten handlar mest om mikroRNA-påverkan.
The report of this unusual case last September was just the latest shock from a bracing new field, the science of consciousness. Questions once confined to theological speculations and late-night dorm-room bull sessions are now at the forefront of cognitive neuroscience. With some problems, a modicum of consensus has taken shape. With others, the puzzlement is so deep that they may never be resolved. Some of our deepest convictions about what it means to be human have been shaken.
One main system-level finding is that a surprisingly large proportion of the genome is expressed in brain -- around 80 percent of all identified genes. Most of these are expressed in only a relatively small subset of genes ("70.5% of genes are expressed in less than 20% of total cells", not together in the same 20%). In other words, the distribution of gene expression is very broad, with a long tail.
The RCMP is taking "very seriously'' a recent threatening letter signed by a group claiming to be a new cell of the FLQ, a Quebec terrorist group active in the 1960s and 1970s.
...
The letter adds that "a combination of vehicles, letter bombs, remote-control explosive devices will be used and most of these devices are already in place.''
Parents who install the monitoring software on their home computers would be able to find out what name, age and location their children are using to represent themselves on MySpace. The software doesn't enable parents to read their child's e-mail or see the child's profile page and children would be alerted that their information was being shared. The program would continue to send updates about changes in the child's name, age and location, even when the child logs on from other computers.

Det finns massor av muslimer som kämpar för demokrati och frihet. Skilj fundamentalism och verkligt moderat religionstolkning samt mer sekulära muslimer och se människan. Inte så få i Storbritannien (~41 procent) och Holland (~34 procent) vill dock ha någon form av sharialagar, vilket ju inte är kompatibelt med våra samhällen. Enligt Channel 4 förekom det otrevliga budskap även bland muslimer som är kända som moderata.
"Europe is the leading region in terms of globally collaborating FLOSS software developers, and leads in terms of global project leaders, followed closely by North America (interestingly, more in the East Coast than the West), Asia and Latin America face disadvantages at least partially due to language barriers, but may have an increasing share of developers active in local communities."
"Weighted by regional PC penetration, central Europe and Scandinavia provide disproportionally high numbers of developers; weighted by average income, India is the leading provider of FLOSS developers by far, followed by China."
"The existing base of quality FLOSS applications with reasonable quality control and distribution would cost firms almost Euro 12 billion to reproduce internally. This code base has been doubling every 18-24 months over the past eight years, and this growth is projected to continue for several more years."
"The existing base of FLOSS software represents a lower bound of about 131.000 real person-years of effort that has been devoted exclusively by programmers. As this is mostly by individuals not directly paid for development, it represents a significant gap in national accounts of productivity. [...]"
"Defined broadly, FLOSS-related services could reach a 32% share of all IT services by 2010, and the FLOSS-related share of the economy could reach 4% of European GDP by 2010. [...]" "[...] FLOSS and proprietary software show a ration of 30:70 (overlapping) in recent job postings indicating significant demand for FLOSS-related skills."
"Russia thus serves as a model for authoritarian-minded leaders in the region" and is a "pervasive influence" Mr Puddington added, with Freedom House pointing out that Russia-oriented states Belarus, Turkmenistan and Uzbekistan "are among the world's worst" in human rights terms.
Iran's geo-strategic interests in the region are easy to see: It desperately needs political allies and new markets for its goods as it comes under increasing pressure from Europe and the United States over its nuclear program. With some money to burn, Ahmadinejad is looking to buy some friends and support among leaders in a region that is turning increasingly hostile to the United States, free trade and drug erradication programs.
An "alternatively spliced" intron is one which can be spliced in two or more different ways, resulting in different protein sequences. It is one of the chief ways that our 25,000 or so genes can end up making 100,000 or so proteins.
Romanian skull dated to plus 35,000 years could be the product of Human-Neanderthal intercave love. I'm guessing this kid got beat up a lot. By humans and Neanderthals. Because cave children can be cruel.
