and that this preference can be abolished by exposing the fish to ethanol. Scary robotporfiri and Macri along with students Valentina Cianca and Tiziana Bartolini hypothesized that robots could be used to induce fear as well as affinity
To determine whether alcohol would affect fear responses the researchers exposed separate groups of fish to different doses of ethanol in water.
Ethanol has been shown to influence anxiety-related responses in humans rodents and some species of fish.
The zebrafish exposed to the highest concentrations of ethanol showed remarkable changes in behavior failing to avoid the predatory robot.
Acute administration of ethanol causes no harm and has no lasting effect on zebrafish.##These results are further evidence that robots may represent an exciting new approach in evaluating
and evaluated whether the results obtained therein were sensitive to ethanol administration. They placed test subjects in a two-chamber tank with one well-lit side and one darkened side to establish which conditions were preferable.
Ethanol exposure significantly modulated these fear responses as well abolishing the preference for the light compartment
Among ethanol-exposed fish there were many more who were unaffected by the robotic predator preferred the dark compartment
Three groups of fish were treated with varying doses of ethanol in water#zero percent (control group) 0. 25 percent and 1 percent by volume.
The two ethanol-exposed groups deviated significantly from this pattern spending more time in other regions of the tank.
The process for creating Portland cement a key ingredient in modern concrete requires fossil fuels to burn calcium carbonate (limestone) and clays at about 1450 degrees Celsius (2642 degrees Fahrenheit.
When they detect the current they need for navigation they power back on slip into the current then power off again to conserve fuel as the current carries them to a target location.

Fuel Since the Biolite will burn almost any biomass fuel; from wood, pine cones, leaves, pellets, rice husks, even dung, it means fuel need not be carried,
unlike bottles for petroleum or gas burners that cannot be carried on airplanes and must be sourced at destination.
whereby the thin gas layer that burns around a solid fuel is separated and added to oxygen to burn more efficiently.
and the vent open to allow oxygen flow before the fire is started using whatever forest fuels are available.

We are still massively dependent on fossil fuels even though they are limited a resource. But, a team of scientists at the University of Illinois at Chicago have figured out#a way to make synthetic gas inexpensively,
using carbon dioxide and carbon nanofibers.####The first step in the process of creating synthetic gas requires the conversion of carbon dioxide into carbon monoxide.
Many scientists have attempted this before, but previous experiments always required silver, along with an ionic liquid (like a salt solution), to trigger the reaction.
The use of silver is obviously too expensive to make synthetic gas a feasible option for commercial use,
##The scientists believe that using super-thin#graphene sheets could make the process even more efficient, making synthetic gas less of a concept and more of a reality.

They also explain that while methane, ethane, propane and butane gasses are released in the process,
the machine is equipped with an off-gas filter that disintegrates these gases into water and carbon.
Lastly, commentators from around the world are anxious to know if and where they can purchase a machine.
Typically made from petroleum, it is estimated that 7%of the#world s annual oil production#is used to produce
and manufacture plastic. That is more than the oil consumed by the entire African continent. Plastic s carbon footprint includes landfilling and incineration,
since sadly, its recycle rate is dismally low around the globe. Plastic trash is also polluting our oceans and washing up on beaches around the world.
A Japanese company called#Blest#created a small, very safe and easy to use machine that can convert several types of plastic back into oil.
If we convert it into oil, we save CO2 and at the same time increase people s awareness about the value of plastic garbage,##says Akinori Ito, CEO of Blest.
The result is a crude gas that can fuel things like generators or stoves and,
One kilogram of plastic produces almost one liter of oil. To convert that amount takes about 1 kwh of electricity,

#Quantum gas goes below absolute zero It may sound less likely than hell freezing over, but physicists have created an atomic gas with a sub-absolute-zero temperature for the first time1.
Their technique opens the door to generating negative-Kelvin materials and new quantum devices, and it could even help to solve a cosmological mystery.
Physicists later realized that the absolute temperature of a gas is related to the average energy of its particles.
Schneider and his colleagues reached such sub-absolute-zero temperatures with an ultracold quantum gas made up of potassium atoms.
This result, described today in Science1, marks the gas s transition from just above absolute zero to a few billionths of a Kelvin below absolute zero.
Another peculiarity of the sub-absolute-zero gas is that it mimics'dark energy''the mysterious force that pushes the Universe to expand at an ever-faster rate against the inward pull of gravity.
Schneider notes that the attractive atoms in the gas produced by the team also want to collapse inwards,
#Liquid storage could make hydrogen a feasible fuel A process for extracting hydrogen from a liquid fuel could remove one of the biggest hurdles to a'hydrogen economy,
They have developed a catalyst that harvests the gas from methanol, a liquid fuel that#unlike hydrogen itself#can be transported easily
and stored. Matthias Beller, a chemical engineer at the University of Rostock in Germany, and his colleagues hope that methanol might one day be sluiced through pipelines
Unfortunately, because hydrogen is a gas it is difficult to store and transport safely unless compressed or liquefied,
Many chemists have spent decades studying how best to trap hydrogen for use as a fuel.
It is straightforward to turn hydrogen into the liquid fuel: a well-known reaction combines hydrogen and carbon monoxide gases using commercial catalysts.
Yet to release the gas, chemists have had previously to heat liquid methanol to 200#C at 25-50 times atmospheric pressure.
because it is about the same temperature as the waste heat from an operating hydrogen fuel cell.
That means that it may be possible to combine a methanol-hydrogen reaction with a fuel cell that guzzles up the gas to produce electricity.
hydrogen fuel cells are twice as efficient as fuel cells that directly run on methanol, for instance. Not everyone agrees with Beller and Tsang.
Olah argues that a future economy could use methanol directly as a liquid fuel, so the world should work on ways to produce it#perhaps by capturing carbon dioxide.

Anstie and his team shine the laser onto a sample of gas. Since each molecule in the universe absorbs light at different optical frequencies,
It also has to be cheap enough to compete with traditional fossil fuels. That been a high hurdle for devices called solid oxide fuel cells (SOFCS) that convert fuelsuch as methane and hydrogenirectly to electricity without burning them.
But now researchers report that theye come up with a new recipe for making key components in one type of SOFC more cheaply,
There, they react with molecules in the fuel generating water, carbon dioxide, and electricity. The electricity is fed through a circuit where it powers our devices,
The devices make electricity at an efficiency that can match a large natural gas-based power plant. But whereas a power plant is huge and costs hundreds of millions of dollars to build,
These devices work best at converting hydrogen gas and oxygen to water and electricity, and even work at lower temperatures around 600°C. Unlike conventional SOFCS the BZY membranes allow the flow not of negatively charged oxygen ions toward the anode,
