someone help me get these moles out of my yard
Using a vibrating metal plate connected to tone generator, Scientist Bruss Pup performs scientific magic by seemingly controlling and manipulating grains of salt to dance in specific patterns.
Explanation: Although the phase of this moon might appear familiar, the moon itself might not. In fact, this gibbous phase shows part of Jupiter's moon Europa. The robot spacecraft Galileo captured this image mosaic during its mission orbiting Jupiter from 1995 - 2003. Visible are plains of bright ice, cracks that run to the horizon, and dark patches that likely contain both ice and dirt. Raised terrain is particularly apparent near theterminator, where it casts shadows. Europa is nearly the same size as Earth’s Moon, but much smoother, showing few highlands or large impact craters. Evidence and images from the Galileo spacecraft, indicated that liquid oceans might exist below the icy surface. To test speculation that these seas hold life, ESA has started preliminary development of the Jupiter Icy Moons Explorer (JUICE), a spacecraft proposed for launch around 2022 that would further explore Jupiter and in particular Europa. Recent observations by the Hubble Space Telescope have uncovered new evidence that Europa, like Saturn’s moon Enceladus, has ice venting from its surface.
I needed some abs (water and peroxide free) tetrahydrofuran, so I just distilled it from benzophenone/sodium under argon with this nice custom made glassware.
Earth-orbiting satellites have found the coldest place on Earth. No surprise: It’s in Antarctica. The coldest of the cold temperatures dropped to minus 135.8 F (minus 93.2 C) — several degrees below the previous record.
Explanation: Blown by the wind from a massive star, this interstellar apparition has a surprisingly familiar shape. Cataloged as NGC 7635, it is also known simply as The Bubble Nebula. Although it looks delicate, the 10 light-year diameter bubble offers evidence of violent processes at work. Above and right of the Bubble’s center is a hot, O star, several hundred thousand times more luminous and around 45 times more massive than the Sun. A fierce stellar wind and intense radiation from that star has blasted out the structure of glowing gas against denser material in a surrounding molecular cloud. The intriguing Bubble Nebula lies a mere 11,000 light-years away toward the boastful constellation Cassiopeia. This natural looking view of the cosmic bubble is composed from narrowband image data, also used to create a 3D model.
It’s a snap… To produce electricity from polonium-210 in a tiny atomic generator. The model shown here is still going strong after a full year of operation. And it has survived impact, vibration, and acceleration tests (requirements for space exploration) without damage, says its designer, The Martin Co. SNAP—system of nuclear auxiliary power—converts heat of radioactive decay into electricity by a series of thermocouples.
Phillip Messersmith is a professor of biomedical engineering at Northwestern University in Illinois, US. Research in the Messersmith group is currently looking at biological adhesives, including the adhesive proteins found in mussels, to develop new biomaterials for the repair, replacement, or augmentation of human tissue.
Since the reaction of sodium-hydroxide and aluminium is really exothermic we need to cool it with a lot ice.
From the left side argon goes in, from the right side nickel-alumium alloy goes in to the overhead stirred reaction flask.
Two independent groups have shown that light can be effectively turned into surface plasmons in graphene if the carbon sheet is made to vibrate. The proposal could solve the problem of how to generate this electronic phenomenon in graphene, and could one day help integrate optical and electrical data processing.
