According to a new report from the prestigious London School of Economics, birth control is a less expensive way to reduce carbon dioxide emissions than most green energy strategies.
sorry i meant to say "some places in Europe" not all of Europe has a decreasing population

this is just silly, want to reduce the birth rate of the world? improve the economies of poor countries. Most of the worlds births are in third world countries. Most "richer" countries, (most of western Europe, the US, japan) have a TFR of 2.1 or less, meaning births replace deaths. The US is a good example of a perfect balance of birth rates CURRENTLY (once the baby boomers from the 30-50s die out things will balance) and even in Europe and Japan the population is decreasing because of a birth rate that is too low. Having a birthrate that is too low is bad for a country as there are shortages of qualified workers. And besides, even if we did cut out diseases and have good health care, people still die young because they eat unhealthy, smoke, drink, themselves to death. So my solution is, improve the economy of third world countries, so they won't want to reproduce as much. :) But like that'll ever happen... haha
A couple of months ago, Sandia National Laboratory, in conjunction with Boston Dynamics (they of Big Dog fame) and DARPA, announced the creation of a robot that could jump 25 feet in the air. Designed for use in urban combat, the robot, named the Precision Urban Hopper (PUH), would give special forces troopers their own lightweight, easily deployable ground UAV.
lol a radio controlled helicopter with a camera duct taped to it would serve as a better UAV no? lol thats just a radio controlled car that can jump 25 feet i don't really see the point
Common sense says that burning a plant you regrow every year is better for the atmosphere than spewing out carbon dioxide that’s been buried underground for eons. But the truth behind biofuels and petroleum often seems to defy common sense. Neither ethanol nor gasoline bubbles out of the ground ready to put in your tank. So to figure out which one does less environmental harm, you have to calculate all the energy that goes into making it.
actually corn fields dont produce nearly as much oxygen as a simple field of grass, and much so less than a forest, so if you are cutting down a field to plant corn fields, you are actually reducing the amount of Co2 that gets taken out of the air because, a corn field cannot compare to a forest, a landscape, or any other natural environment, where life thrives
Features editor Nicole Dyer is back with another SciKu! It's rhythmic, it's subtle, it's all about science; What more could you ask for from this ancient poetic form?

A translation of the above and how to read it natsu no hana utsukushiku saku ame ga fuku not a literal translation, but close enough still in haiku form. flower of summer, blooms ever so beautiful the rain falls softly

In this age of eternal flight delays, traveling from New York to Miami in the scheduled three hours sounds like a fantasy. Yet within a decade, aircraft designer Abe Karem plans to fix that by bypassing congested runways in his tilt-rotor, vertical-takeoff commercial plane, the AeroTrain. Sitting on a helipad with its twin rotors tilted straight up, the craft can take off vertically and fly like a helicopter. Once the plane has reached a safe altitude of 50 feet, the pilot will tilt the rotors forward and fly the craft like an airplane.
I think its a great idea, and like the person above me i hope it does succeed, but the thing is, there are already vtol crafts being made, and while previous aircrafts have killed people, those mistakes should be very much so re-evaluated and fixed, and steps are made towards a better craft. I really would like to see this come into play, now just make it have better fuel efficiency and economy than airplanes, and we're set :)
That is incredible, another step towards self propulsion jets, of course, its a long way from ground take offs and landing and obviously he was not carrying alot of fuel, but bravo for his (and his groups) ingenuity and bravery. Props to those guys, the kind of people who push the limits of science
The transportation program at the Art Center College of Design has produced legendary car designers, including BMW chief of design Chris Bangle and Henrik Fisker, the creator of the Fisker Karma electric supercar. But this year, after professor Bumsuk Lim’s inaugural motorcycle-design class, the buzz is all about bikes, especially Jake Loniak’s exoskeleton motorcycle concept Deus Ex Machina.
i see something a little different being more practical, instead of being held up by straps, lay down on it, and be positioned on the other side, or have something on both sides and sort of stand in the middle so you can lay down on it at high speeds and it offers frontal protection
