Each generation of kids is even luckier than the one before, fortunately things have been happening that way but still I think about the environment that’s being altered to worst. Now scientists say that they can capture carbon from the atmosphere and convert it to fuel, that’s good, maybe we’re not lost after all.

Anyway kids deserve the best, and we should make sure that their life is improved from generation to generation.

The warming glaciers will raise sea level in two main ways. As they melt they add more water and they also add more water as ice breaks off from glacial flows. The incidence of this later phenomenon has blasted in recent years for some glaciers draining the southern Greenland Ice Sheet, much to the mystification of glaciologists. Unable to account for such accelerated ice losses, members of the Intergovernmental Panel on Climate Change declined to include them in their widely cited projection of up to 60 centimeters of sea level rise by 2100.

Using all the data available plus some estimates of what’s going on with all glaciers the glaciologist W. Tad Pfeffer of the University of Colorado managed to estimate the sea raise from 80 centimeters to 200 centimeters by the end of the century. Some researchers also say that the sea rise should be of several meters but this estimate is impossible because its physically untenable once that not enough ice could be pushed through the glacial gates.

These numbers for the sea rise leave many worries since 1 meter of sea rise is a big deal as it would threaten people in many parts of the world.

Have you noticed that our need for food has been contributing for the degradation of the environment and that we need new solutions if our population continues to grow. This degradation comes from pesticides, fertilizers or from overfishing.

Against this backdrop there are a growing amount of people working to refine and popularize a technique that could slash those environmental costs for either fish or vegetable products. The technique is called aquaponics and it integrates fish and hydroponic agriculture in a sort of closed, symbiotic loop. The fish serve as fertilizer factories and the plants as water purifiers. With this idea we maximize production while minimizing environmental costs.

Probably this will be the future of food production of the future which already is in course at Cabbage Hill Farm in Mount Kisco, N.Y.

Those kinds of self sustained techniques may also play an important role in the colonization of infertile planets in the long future but meanwhile we can only hope that this is a way for us to stop the degradation of our planet ecosystems.

The first solar submarine in the world, the Goldfish, was presented a few days ago at the international exposition of Zaragoça. This project only works from sunlight energy.

This submarine gets his energy from five lateral satellites equipped with a total of 300 square meters of solar panels. The energy generated is stored in batteries which after feeds the submarine.

This project belongs to the engineers Martin Pfisterer and Matthuas Zelweger and was developed by the electric company BKW-FMB and the transportation company BLS SA.

This submarine will measure 20 to 30 meters and will hold 20 to 30 passengers. This submarine will be able to submerge up to 200 meters deep and have a consumption of 100 quilowats/hour.

The first dive will be in the first semester of 2011 in the lake Thun, Suisse Alps.

Good luck to this new innovative blend of submarines.

The findings were published on Thursday in the journal science and described clusters of towns and smaller villages connected by complex road networks and housing society doomed by the arrival of Europeans five centuries ago because of the diseases brought by them into the new world.

The settlement now overgrown by the forest consisted of walled towns and smaller villages organized around a central plaza.

The anthropologist Mike Heckenberger from the University of Florida said in a statement: “These are not cities, but this is urbanism, built around towns,”.

“If we look at your average medieval town or your average Greek polis, most are about the scale of those we find in this part of the Amazon. Only the ones we find are much more complicated in terms of their planning,” Heckenberger added.

It took more than a decade for the researchers to map the lost communities with the help of the available satellite images.

Researchers are finding more and more that the Americas were home to many prosperous and impressive societies and large cities.

These findings come to prove that the virgin tropical forests in north-central Brazil aren’t in fact that virgin but heavily affected by past human activity.

These finding also come to prove that Americas societies weren’t that undeveloped at all.

The pen-tailed tree shrew feeds on nectar of an ever flowering plant, the bertam palm, which is also the primary food source for many other animals as well. Yeast cells in the palm’s flowers ferment its nectar, which can contain up to 3.8% alcohol. Comparing all living plants that produce alcohol this one is the one that has the highest concentrations of alcohol.

Despite researchers not finding any inebriation effects the reality is that the tree shrews meet or surpass the legal intoxication limit of 1.4 grams of alcohol per kilogram of body mass every 3 days. Just for you to get an idea the 1.4 grams of alcohol per kilogram of body mass in human terms is the equivalent to an average woman drinking nine glasses of wine or beer in a 12-hour period.

This amazing picture was taken on June 3, 1964 which is before I was born. The development of human society has been extraordinary these last few hundred years and to prove it where is one of many amazing pictures of great deeds.

Just before the time we were getting color TV we also had men’s walking in space.

The astronaut managed to walk in space with the help of a hand-held maneuvering oxygen-jet gun and an 8 meter tether. The gun held in his right hand ran out of fuel 3 minutes after he started the space walk making the astronaut use the tether to come back to the ship. The visor of his helmet is gold-plated to protect him from the unfiltered rays of the sun.

Hope you enjoy this fantastic picture.

Though the stones were only erected in 2500 B.C. there are evidences of burials since 3000 B.C.

It seems like the local was used to only bury elements of one family being the first one at 3000 B.C. and then as the family gown up more and more bodies were then buried afterwards.

At the time bodies used to be cremated and methods of rating how old were those cremated bones just came to the access of researchers allowing the recent dating of the remains found at Stonehenge.

British archaeologists say it probably was a cemetery for the ruling dynasty responsible for erecting Stonehenge.

The answer to why researchers found up to 240 people remains is because Stonehenge staged as burial place for several generations of the same single elite family. The clue comes from the small number of burials in the earliest period and the larger numbers in the later centuries, as offspring would have multiplied said Andrew Chamberlain, Sheffield archaeologist.

When tissues are damaged in plants they emit green-leaf volatiles which are attractive to social wasps. This happens because normally plants are damaged by parasites like caterpillars and wasps are their predator, so when a plant is damaged and emits those green leaf volatiles the parasitic wasps come to check it out to see if their meal is around.
Researchers have already found that orchids, which are known by the diversity of their pollination systems, also employ chemical deceit for the attraction of pollinators but this new way is just too awesome.
The orchid Epipactis helleborine is a typical wasp flower, exhibiting physiological and morphological adaptations for the attraction of pollinating social wasps. Despite the large nectar reward that these orchids offer, they’re overlooked by other potential pollinators because of their characteristics.
The wasps are attracted to those orchids because their flowers also emit green-leaf volatiles that trick the wasps to come to them, when the wasp reaches the designated orchids they just forget the motive why they are there and just take attention on the large nectar reward that the orchids offer.
This is the first example in which green-leaf volatiles have been implicated in chemical mimicry for the attraction of pollinating insects.
