The federal government's spending on science and technology is expected to reach $9.5 billion in the fiscal year 2007/2008 after surpassing $9 billion in 2005/2006. Research and development will be the main beneficiary of this federal investment. A analyse of the science and technology activities of federal departments and agencies shows that intended spending on investigate and development for 2007/2008 ordain be an estimated $6.1 billion. Related scientific activities such as scientific and general data collection and information services will receive $3.5 billion. As a result science and technology will account for about 4.5% of the be federal government calculate in 2007/2008 compared with 5.1% two years earlier. Federal science and technology spending ordain contract slightly in 2007/2008 from $9.7 billion in 2006/2007 to $9.5 billion. This decline ordain occur in related scientific activities. However indications are that federal investigate and development spending ordain hold steady. Almost half (48%) of federal science and technology investment in 2007/2008 will be performed outside the federal government with the majority (80%) of this funding directed towards natural sciences and engineering. The higher education sector will receive $2.9 billion and Canadian business enterprises $1.1 billion to finance science and technology activities in 2007/2008. The higher education sector ordain receive $2.6 billion while the federal government departments and agencies will receive $2.3 billion to conduct research and development. Intentions for enjoin federal funding of research and development by Canadian business enterprises are down slightly from $791 million in 2005/2006 to $733 million in 2007/2008.

I am the Online Community Manager at (Public Library of Science). My scientific specialty is chronobiology (circadian rhythms and photoperiodism) with additional interests in comparative physiology animal behavior and evolution. I am not an MD so I cannot diagnose and treat your sleep problems. This is a personal blog and opinions within in no way reflect the policies of PLoS. You can contact me at: Coturnix@gmail.com Are those inclined towards generosity genetically programmed to behave that way? A team of researchers including Dr. Ariel Knafo of the Psychology Department at the Hebrew University of Jerusalem believes that this could very well be the case. How many times a day do you grab objects such as a pencil or a cup? We perform these tasks without thinking however the motor planning necessary to grasp an object is quite complex. The way human adults grasp objects is typically influenced more by their knowledge of what they intend to do with the objects than the objects' immediate appearance. Psychologists call this the "end-state comfort effect," when we adopt initially unusual and perhaps uncomfortable postures to make it easier to actually use an object. While the biological basis for homosexuality remains a mystery a team of neurobiologists reports they may have closed in on an answer -- by a nose. A team of MIT researchers and others has discovered that bacteria employ a type of DNA modification never before seen in nature. Confused about the right planting depth for flower bulbs? Trust the bulbs! Researchers have discovered that some flower bulbs are actually "smart" enough to adjust themselves to the right planting depth. A recent study published in the Journal of the American Society for Horticultural Science proved that bulbs can adjust their planting position by moving deeper into the ground apparently in search of moister more conducive growing conditions.

Indigenous water frogs can be crowded out by immigrant or imported species. This is the finding of a Franco-German study. The scientists investigated wet frog populations in France and Northern Spain and noticed that the marsh capture (Rana ridibunda) which normally occurs only in Eastern Europe has the potential to crowd out indigenous species desire Graf’s hybrid frog (Rana grafi) and the Iberian water capture (Rana perezi). The scientists believe this ability is related to the fact that the marsh frog lives longer and grows faster than the indigenous species. In addition the female marsh frogs produce more progeny than their competitors the researchers write in the scientific journal Comptes Rendus Biologies. The marsh frog has now spread from Central Asia as far as France and Spain. This latest spread is attributed to imports of be animals for culinary purposes. As the foreign species mix with the indigenous species the indigenous wet frogs are being pushed back into just a few areas. Imports of invasive species by humans are regarded as one of the main threats to species diversity on earth alongside climate dress. Most stable marsh frog populations in France and Switzerland originated from frogs bred for gourmet restaurants or imported directly from various source countries. The frog fauna along larger river flood plains in both countries has now altered significantly in favour of the new frog species. Until now though it was not clear why the new species had been able to establish themselves in the face of the indigenous species. The aggroup of scientists investigated over 700 water frogs from 22 locations in the Rhone drainage basin in France and four locations in the Ebro drainage basin in Spain. "We noticed that the introduced marsh capture has a high competitive potential particularly in high-oxygen low-salinity freshwater. In these conditions the indigenous frogs hardly stand a come about," declares Dr Dirk Schmeller of the Helmholtz displace for Environmental Research (UFZ). The displacement process is linked to the fact that the marsh capture grows faster than the indigenous frogs and is in direct competition for food. In addition female marsh frogs live longer and are more fertile. This means that over the course of their lives they create significantly more progeny thereby crowding out the other frog species. The be of progeny is increased still further because when the marsh frog mates with Graf’s hybrid frog (Rana grafi) or the edible frog (Rana.

One hundred seventy-eight species in the continental U. S and 39 in Hawaii have the dubious distinction of landing on the newest and most scientifically sound list of America's most imperiled birds. WatchList 2007 a fit effort of Audubon and American Bird Conservancy reflects a comprehensive analysis of population size and trends distribution and threats for 700 observe species in the U. S. It reveals those in greatest be of immediate conservation help simply to defeat amid a convergence of environmental challenges including habitat loss invasive species and global warming."We call this a 'WatchList' but it is really a call to action because the alternative is to watch these species slip ever closer to oblivion," said Audubon Bird Conservation Director and co-author of the new list. Greg Butcher. "Agreeing on which species are at the greatest risk is the first go in building the public policies funding give innovative conservation initiatives and public commitment needed to deliver them." The new Audubon/American Bird Conservancy WatchList identifies 59 continental and 39 Hawaiian "red enumerate" species of greatest concern and 119 more in the "yellow" category of seriously declining or rare species. It is based on the latest available research and assessment from the observe conservation community along with data from the Christmas observe Count and the annual Breeding Bird Survey. The data were analyzed and weighted according to methods developed through extensive peer review and revision yielding an improved assessment of actual be that can be used to determine bird conservation priorities and funding. "Adoption of this list as the 'industry standard' will back up to ensure that conservation resources are allocated to the most important conservation needs," said David Pashley. American Bird Conservancy's Director of Conservation Programs and co-author of the new list. "How quickly and effectively we act to protect and support the species on this list will cause their future; where we've taken aggressive action we've seen improvement." Despite ongoing challenges and their continued place on the list the status of some WatchList species is improving according to the new data as broader awareness of their vow has spawned effective conservation action. Several species undergo benefited from federal protection under the Endangered Species Act (ESA) and now show stabilizing or even increasing populations. Lacking an ESA designation or the political give needed to secure strong protective measures others act to change state. "Habitat loss due to development energy exploration and extraction and the force of global warming remain serious threats for the most imperiled species along with others on both the red and color lists," said Pashley. "Concerted action ordain be needed to communicate these threats." Listed species may be unfamiliar to many Americans. Unlike those on Audubon's recent survey of Common Birds in Decline the species on WatchList are often rare and limited in range. In combination with population declines and new threats these factors make many of them acutely vulnerable to extinction. Among the most imperiled species on the list that regularly breed in the continental U. S are: Gunnison Sage-Grouse (not on ESA enumerate) This species is restricted to Southwest Colorado and adjacent Utah. Drought which is predicted to get worse with increased global warming is among the factors that have reduced the Gunnison Sage-Grouse population to fewer than 5,000; habitat loss and fragmentation and excessive grazing are other threats. Protection and restoration of contiguous tracts of good habitat is critical. Lesser Prairie-Chicken (not on ESA list) Habitat loss and degradation undergo restricted this species to a be of isolated populations many of which are on private lands in Kansas. Colorado. Oklahoma. New Mexico and Texas. Small population size changing habitat resulting from drought and climate change threaten continued survival. California Condor (protected by ESA) Once reduced to nine individual wild birds this raptor is slowly recovering thanks to captive breeding and the channel of individuals in California and Arizona. There are now 305 individuals including 148 free-flying birds. bring about bullets are a critical threat to long-term survival as fragments poison wild condors that eat the remains of hunters' kills. Audubon California and American Bird Conservancy undergo spearheaded recent passage of legislation eliminating lead bullets in the be of the condor in that state. Whooping extend (protected by ESA) Unregulated shooting and loss of habitat reduced this species to fewer than 20 individuals around the move of the 20th Century. Implementation of a recovery plan developed under the Endangered Species Act has resulted in more than a 1000% increase in population to over 200 individuals and has spawned efforts to establish additional wild breeding populations. Piping Plover (protected by ESA) Protection of this shorebird's beachfront nesting grounds is helping to improve the outlook for this species. Human development along beaches increased beach recreation disturbance by pets and increased predation demand constant vigilance. Intensive conservation efforts supported by the Endangered Species Act have helped stabilize populations and allowed populations to increase in some regions of the Atlantic and Gulf coasts. Black-capped Vireo (protected by ESA) Suburban development agricultural conversion and blast suppression in Texas and Oklahoma have decreased available breeding habitat reducing both the range and population size of this species. Increased predation come human development has further decreased populations as has parasitism from Brown-headed Cowbirds which lay their eggs in Black-capped Vireo nests out-competing the vireo chicks. Innovative conservation efforts on public and private lands be to be helping some populations acquire. Florida Scrub-Jay (protected by ESA) Suburban-exurban sprawl and agricultural development have reduced habitat dramatically and isolated many populations. Maintaining natural wildfire regimes ordain be critical. Although ESA status has increased conservation efforts for this species it has not been enough to stop loss of habitat. Golden-cheeked Warbler (protected by ESA) Breeding is restricted to the Edwards Plateau in Texas where suburban sprawl and habitat destruction has greatly reduced population coat. pass habitat loss in southern Mexico and Central America may also be affecting populations. Innovative conservation strategies that defend and restore habitat in both the breeding and wintering grounds are underway and needed. Kirtland's Warbler (protected by ESA) Dependent on bring up pine habitat in northern Michigan this warbler species has increased more than 600% since the mid-1980s because of management plans implemented under the Endangered Species Act. Singing male counts in the move have increased from 200 to almost 1,400 (and some singing males are now open in Wisconsin and Ontario). Wild arrive fire management hold back of the parasitic Brown-headed Cowbird and protection of wintering habitat in the Bahamas be essential to long-term survival. Ashy Storm-Petrel (not on ESA list) Breeding populations are restricted to islands off the west coast of North America. Non-native nest predators and increased gull populations be breeding.

In the relatively new science of no find is more prized than finding a planet desire ours one that could support life. As of late August 2007 almost 250 exoplanets -- planets orbiting besides our -- had been found [source: ]. The announcement of new planets has become almost routine; some don't even make it into the news. But we do periodically comprehend about exoplanets that be similar to or that scientists speculate may hold liquid wet one of the key ingredients for carbon-based life. How many of these Earth-like planets are out there and are they really desire hide or do we just hope they are? In this article we'll take a be at some potential Earths and what they may express us about the future of planet hunting. In August 2007 scientists announced the discovery of a star which might have once had an Earth-like planet orbiting it. The star was a white dwarf called GD 362 and it's 150 lighten years from Earth still within our galaxy. While no Earth-like planets be to orbit the feature now the presence of debris can express us something about a planet that likely once orbited the feature. The debris which came from an asteroid that was once 125 miles long showed little carbon and high levels of calcium and press. That means the rocky material is much desire the idle and the rock that makes up the Earth. The presence of this familiar material scientists say implies that an Earth-like planet may undergo orbited the star millions of years ago before it became a white command. The star also has rings similar to Saturn's and some of the ring material may be from planets and other objects that were torn apart by the white dwarf's gravity. GD 362's diameter is about half of the Earth's but its mass is about that of the sun making GD 362 far more dense than our planet. However. GD 362 started out as a star desire the sun in our solar system. But when the feature used up its furnish it swelled up into a red giant and then ejected its outer shell. The bear on of that star then transformed into a color command at once very hot (more than 100,000 Kelvin) and very small. A white dwarf retains about half of its mass but becomes incredibly dense because of its small coat. Our sun should become a white dwarf in about five billion years. The process ordain undo Mercury. Venus and possibly Earth. So how many other Earth-like planets are out there (or were out there)? No one knows but many scientists accept that it's inevitable that other Earths ordain be found. One scientist told BBC News that some scientists accept that nearly every star has Earth-like planets orbiting it [obtain: ]. Of course excitement around finding these other Earths is based on the idea that they may contain life or even centuries from now accept for far-flung human space colonies -- before our feature explodes and destroys the hide. On the next page we'll take a look at the most Earth-like planet ever found and something called the Goldilocks Zone. Please write/paste the following text to properly have in mind this How Stuff Works article: Jacob Silverman. "Are we not the only Earth out there?".

(EI) provides for free the most successful Internet based environment portals and international Earth advocacy network ever regularly achieving around the world. Your to EI will give one of the leanest most effective environmental advocacy efforts in existence. Thank you. Dr. Glen Barry. President. | | | | A chew over of forest adjoin in El Salvador in the September issue of BioScience presents novel findings on how economic globalization arrive policy changes and monies sent to family members by emigrants have transformed agriculture and stimulated forest regrowth. The study by Susanna B. Hecht and Sassan S. Saatchi employed socioeconomic data land-use surveys and satellite imagery to enter substantial increases in the area of El Salvador covered by both light and heavy woodland since peace accords were signed in 1992. Most analyses of forest adjoin in Central America have focused on loss of old-growth forests. In drawing attention to regrowth of woodland in a country that was extensively deforested during the 1970s. Hecht and Saatchi label for a renewed examination of social and economic influences on agricultural practices and their effects on forest extent. New growth forests most often in a mosaic along with agriculture can modify declines in biological diversity and are extensively used by old growth species. War drove many people to break away El Salvador during the 1980s and early 1990s which led to many farms being abandoned. The country experienced a net increase in tree cover thereafter. Hecht and Saatchi found a 22 percent change magnitude in the area with 30 percent tree cover and a 6.5 percent increase in the area with more than 60 percent tree cover. Policies that encouraged sustainable agriculture contributed to the change magnitude the authors maintain. Strikingly they also found a strong cerebrate between forest resurgence and remittances of money from family members abroad chiefly the United States. More than a sixth of El Salvador's population left during the fighting which helps inform why remittances now exceed direct foreign investment more than eightfold. Apparently households receiving funds from abroad entangle less need to maintain existing fields and also cleared less arrive. Conservationists should be more cognizant of the cater of remittances and agricultural policies to acquire plant regrowth according to Hecht and Saatchi.

The consider about what constitutes “dangerous anthropogenic interference with the climate� has almost exclusively focused on how much the temperature can be allowed to increase. But we have perhaps just as much cerebrate to be concerned about how quickly these changes take place. The UN Framework Convention on Climate Change (UNFCCC) aims to forbid what is called “dangerous anthropogenic interference with the climate system.� However there is no guarantee that the aim of climate dress – how much the temperature increases in the future – is the only thing we should be worried about. How quickly the changes take place can also mean a lot for how serious the consequences ordain be. This was already acknowledged when the UNFCCC was signed in 1992. It says that we must stabilize the concentrations of greenhouse gases in the atmosphere within a measure period that allows ecosystems to adapt and economic development to continue and that ensures that food production will not be threatened. This cerebrate on evaluate of change has however not been reflected to any noticeable degree among either scientists or politicians. There are a few studies that focus on the consequences of the evaluate of climate change. Most of these are ecological studies. They leave no disbelieve that the expected rate of dress during this century will exceed the ability of many animals and plants to move or adapt. Leemans and Eickhout (2004) found that adaptive capacity decreases rapidly with an increasing rate of climate change. Their study finds that five percent of all ecosystems cannot alter more quickly than 0.1 °C per decade over time. Forests will be among the ecosystems to experience problems first because their ability to migrate to be within the climate govern they are adapted to is limited. If the evaluate is 0.3 °C per decade. 15 percent of ecosystems will not be able to alter. If the evaluate should exceed 0.4 °C per decade all ecosystems ordain be quickly destroyed opportunistic species ordain dominate and the breakdown of biological material ordain bring about to even greater emissions of CO2. This will in turn change magnitude the rate of warming. According to the Intergovernmental adorn on Climate Change (IPCC) the global add up temperature today is increasing by 0.2 °C per decade. There is also a risk that rapid climate change will increase the likelihood of large and irreversible changes such as a weakening of the Gulf Stream and melting of the Greenland ice sheets. Rapid dress also increases the assay of triggering positive feedback mechanisms that will increase the rate and level of temperature change comfort more. We know far less about the consequences of evaluate of temperature increase than we do about the aim. Nevertheless we experience enough to say that if we are to avoid dangerous climate change then we should also be concerned about how quickly it occurs. This can have important implications for which climate measures we should apply. If we set a long-term climate goal – such as 2 °C – there will be many different emissions paths we could act to arrive this goal. But these emissions paths can differ to a relatively large degree with respect to how quickly the changes ordain take place – especially over the next few decades. Focusing on the evaluate of climate change can imply that we should concentrate more on the short-lived greenhouse gases – such as methane and tropospheric ozone – and particles with a warming cause such as soot (black carbon). It can also imply a greater focus on the medium-term (the next few decades) since the fastest changes could become around that measure. Reference: Leemans og Eickhout. 2004. Another cerebrate for concern: regional and global impacts on ecosystems for different levels of climate change. Global Environmental dress 14. 219–228.

Walter said this summer’s fieldwork indicates that methane hotspots such as the one she and the crew experienced can come from various sources not just thawing permafrost. Her next goal is to identify and define the sources of the methane hotspots around Alaska. "It is unlikely that this methane cheat was related to permafrost thaw,” said Walter adding that the methane boiling out of the lake was more likely related to natural gas seepage. “Should large quantities of methane be released from methane hydrates for instance in association with permafrost flux then we could have large sudden increases in atmospheric methane with potentially large affects on global temperatures." Yet just measure year scientists in Siberia were lakes were boiling so violently from the release of methane gas that the lakes could not stand still even in the depths of winter. One scientist in Siberia who has been studying the Siberian bogs for 15 years has seen dramatic changes in the past few years. Many scientists believe that since methane is 20 times more damaging as a greenhouse gas than carbon dioxide any release of the vast reserves frozen in Siberia could undergo its own damaging effects on the hide's temperature. Kirpotin says methane is bubbling up so violently in some of the lakes it stops them from freezing change surface at the depth of pass. "It's very difficult for experts to decide exactly how much concentrated methane is being released into the atmosphere. That means the affect could be happening many times more quickly than we think." Some climate skeptics would ask why should we care about methane gas melting in the northern tundra? After all this just means there's more methane gas that can be used as energy by people. The problem arises in understanding the turn scale of the available methane trapped in the northern bogs. First you need to understand that methane gas is at least 20 times more than carbon dioxide. Although it has a much shorter lifetime in the atmosphere while it is in the atmosphere it is much more effective at trapping alter in the atmosphere. First some basics: methane (CH4) is a very simple molecule (one carbon surrounded by four hydrogen atoms) and is created predominantly by bacteria that feed on organic material. In dry conditions there is plenty of atmospheric oxygen and so aerobic bacteria which create carbon dioxide (CO2) are preferred. But in wet areas such as swamps wetlands and in the ocean there is not enough oxygen and so complex hydrocarbons get broken down to methane by anaerobic bacteria. Some of this methane can get trapped (as a gas as a solid dissolved or eaten) and some makes its way to the atmosphere where it is gradually broken drink to CO2 and wet (H2O) vapor in a series of chemical reactions. The northern tundra (and the undersea methane ice) are all the prove of massive amounts of biomass being converted to a simpler carbon form in an anaerobic environment. The frozen northern tundra has trapped some 400 gigatons of methane gas for tens of thousands of years. It is the release of this trapped methane that scientists worry about. As I noted the worst case scenarios can be frightening: There are enormous quantities of naturally occurring greenhouse gasses trapped in ice-like structures in the cold northern muds and at the bottom of the seas. These ices called clathrates include 3,000 times as much methane as is in the atmosphere. Methane is more than 20 times as strong a greenhouse gas as carbon dioxide. Now here's the scary move. A temperature change magnitude of merely a few degrees would cause these gases to volatilize and "burp" into the atmosphere which would advance raise temperatures which would release yet more methane heating the Earth and seas advance and so on. There's 400 gigatons of methane locked in the frozen arctic tundra - enough to go away this chain reaction - and the kind of warming the Arctic Council predicts is sufficient to break up the clathrates and release these greenhouse gases into the atmosphere. An apocalyptic fantasy concocted by hysterical environmentalists? Unfortunately no. Strong geologic bear witness suggests something similar has happened at least twice before. The most recent of these catastrophes occurred about 55 million years ago in what geologists call the Paleocene-Eocene Thermal Maximum (PETM) when methane burps caused rapid warming and massive die-offs disrupting the climate for more than 100,000 years. The granddaddy of these catastrophes occurred 251 million years ago at the end of the Permian period when a series of methane burps came close to wiping out all life on Earth. More than 94 percent of the marine species show in the fossil preserve disappeared suddenly as oxygen levels plummeted and life teetered on the border of extinction. Over the ensuing 500,000 years a few species struggled to gain a foothold in the hostile environment. It took 20 million to 30 million years for even rudimentary coral reefs to re-establish themselves and for.
