Now, though, a group of scientists has fashioned a wormhole prototype out of a material commonly used in the fringe invisibility cloak industry. Alvaro Sanchez of the Universitat Autònoma de Barcelona, lead author on a study just published in Scientific Reports, says they’ve built a device that, if put inside a magnetic field, will be magnetically undetectable. If a magnetic field travels through the device, the magnetic field disappears from space completely and pops out the other side, similar to the way a wormhole bends space-time so that two distant locations become connected. Scientists explore the origins of energy in chemical reactions using experimental quantum chemistry. (Phys.org)—One thing that all chemical reactions have in common—whether they are the reactions that take place inside a battery, the metabolic reactions inside a living organism, or the combustion reactions that cause an explosion—is that they all involve some kind of change in energy.
On a large scale, the changes in energy of a reaction can usually be measured in various ways for practical purposes, but attempting to understand the fundamental origins of this energy at smaller and smaller scales becomes more complicated, especially as chemistry enters the quantum realm. In a new study, Cornell University chemists Dr. Martin Rahm and Prof. Roald Hoffmann (who received the Nobel Prize in Chemistry in 1981 for theories on the course of chemical reactions) have explored a new way of understanding the origins of energy in chemical reactions at the quantum level. Their paper is published in the Journal of the American Chemical Society. Energy breakdown. Scientists turn oily soil into fertile ground. Rice University scientists are cleaning soil contaminated by oil spills in a way that saves energy and reclaims the soil's fertility.
They use a process known as pyrolysis, which involves heating contaminated soils in the absence of oxygen. This approach is much better for the environment than standard incineration techniques for fast remediation, said Rice environmental engineer Pedro Alvarez. "Our original goal was to speed the response to oil spills, but our aspiration was to turn contaminated soil into fertile soil," said Alvarez, the George R. Brown Professor and chair of Rice's Civil and Environmental Engineering Department. The new paper by Alvarez and his Rice colleagues in the American Chemical Society journal Environmental Science and Technology demonstrates how they've done just that. Off-shore oil spills tend to get the most attention, Alvarez said, but 98 percent of spills - more than 25,000 per year—occur on land.
Giant Galaxies May Be Better Cradles for Habitable Planets. Galaxies like the Milky Way may not be the best cradles of life in the universe — giant galaxies devoid of newborn stars and at least twice as massive as the Milky Way could host 10,000 times more habitable planets, researchers say.
In the past 20 years, astronomers have confirmed the existence of nearly 1,900 planets that orbit stars other than our sun. These findings have led researchers to speculate which moons, planets and stars might be the best at supporting recognizable forms of life. Scientists have even investigated whether there might be a galactic habitable zone in the Milky Way — a region of the galaxy favorable to the formation and evolution of habitable worlds. Why we're smarter than chickens: Team uncovers protein part the controls neuron development. Toronto researchers have discovered that a single molecular event in our cells could hold the key to how we evolved to become the smartest animal on the planet.
Benjamin Blencowe, a professor in the University of Toronto's Donnelly Centre and Banbury Chair in Medical Research, and his team have uncovered how a small change in a protein called PTBP1 can spur the creation of neurons - cells that make the brain - that could have fuelled the evolution of mammalian brains to become the largest and most complex among vertebrates. The study is published in the August 20 issue of Science. Brain size and complexity vary enormously across vertebrates, but it is not clear how these differences came about. Humans and frogs, for example, have been evolving separately for 350 million years and have very different brain abilities. Yet scientists have shown that they use a remarkably similar repertoire of genes to build organs in the body.
