Climate change deniers using dirty tricks from 'Tobacco Wars'
Published: Thursday, July 4, 2013 - 12:21 in Earth & Climate

Fossil fuel companies have been funding smear campaigns that raise doubts about climate change, writes John Sauven in the latest issue of Index on Censorship magazine. Environmental campaigner Sauven argues: "Some of the characters involved have previously worked to deny the reality of the hole in the ozone layer, acid rain and the link between tobacco and lung cancer. And the tactics they are applying are largely the same as those they used in the tobacco wars. Doubt is still their product."

Governments around the world have also attempted to silence scientists who have raised concerns about climate change. Tactics used have included: the UK government spending millions infiltrating peaceful environmental organisations; Canadian government scientists barred from communicating with journalists without media officers; and US federal scientists pressured to remove words 'global warming' and 'climate change' from reports under the Bush administration.

Writing about government corruption in the Indian mining industry, Sauven says: "It will be in these expanding economies that the battle over the Earth's future will be won or lost. And as in the tobacco wars, the fight over clean energy is likely to be a dirty one."

Temperature Drives the Continental-Scale Distribution of Key Microbes in Topsoil Communities

Ferran Garcia-Pichel, Virginia Loza, Yevgeniy Marusenko, Pilar Mateo, Ruth M. Potrafka
Global warming will likely force terrestrial plant and animal species to migrate toward cooler areas or sustain range losses; whether this is also true for microorganisms remains unknown. Through continental-scale compositional surveys of soil crust microbial communities across arid North America, we observed a latitudinal replacement in dominance between two key topsoil cyanobacteria that was driven largely by temperature. The responses to temperature of enrichment cultures and cultivated strains support this contention, with one cyanobacterium (Microcoleus vaginatus) being more psychrotolerant and less thermotolerant than the other (M. steenstrupii). In view of our data and regional climate predictions, the latter cyanobacterium may replace the former in much of the studied area within the next few decades, with unknown ecological consequences for soil fertility and erodibility.

Sound waves put levitation on the move
Technique transports nonmagnetic particles such as cells, water droplets and coffee grounds - acoustic levitation.
Using steady streams of sound waves, engineers maneuvered hovering toothpicks, coffee granules and water droplets through the air, a team from ETH Zurich reports July 15 in the Proceedings of the National Academy of Sciences. Scientists could use the touch-free technique to gently handle delicate or hazardous lab chemicals or to avoid contaminating cells in biological experiments.
Scientists have known for years how to use sound waves to hoist particles in the air, a process known as acoustic levitation. But moving the lifted bits around was more challenging. The sound waves tend to trap a levitated object in a fixed pocket of space.

The new technique moves the pockets around by deforming a field of sound waves, letting researchers transport trapped objects several centimeters.

New Hypothesis Explains Why We Sleep [Preview]

During sleep, the brain weakens the connections among nerve cells, apparently conserving energy and, paradoxically, aiding memory

Sleep must serve some vital function because all animals do it.
Evidence suggests that sleep weakens the connections among nerve cells, which is a surprising effect, considering that strengthening of those connections during wakefulness supports learning and memory.
But by weakening synapses, sleep may keep brain cells from becoming oversaturated with daily experience and from consuming too much energy.

How Your Eyes Search a Scene
Sight-Specific

Isolating one item from the crowded visual environment—such as a favorite brand of cereal in the supermarket or a deer in the forest—is a sophisticated psychological feat, but people accomplish it routinely thousands of times every day.
To search effectively, the brain focuses on a few select attributes, such as color and shape, ignoring other kinds of input. When you are looking for the ketchup bottle, your eyes alight on other red and cylindrical things.
Our eyes jump around, rarely fixating on anything for more than one third of a second. The brain protects us from this disorienting reality by suppressing vision when our eyes are moving.

Nikola Tesla - the unsung scientist:
During his lifetime, Tesla invented fluorescent lighting, the Tesla induction motor, the Tesla coil, and developed the alternating current (AC) electrical supply system that included a motor and transformer, and 3-phase electricity.
Tesla is now credited with inventing modern radio as well; since the Supreme Court overturned Guglielmo Marconi's patent in 1943 in favor of Nikola Tesla's earlier patents. When an engineer (Otis Pond) once said to Tesla, "Looks as if Marconi got the jump on you" regarding Marconi's radio system, Tesla replied, "Marconi is a good fellow. Let him continue. He is using seventeen of my patents."

The Tesla coil, invented in 1891, is still used in radio and television sets and other electronic equipment.
Ten years after patenting a successful method for producing alternating current, Nikola Tesla claimed the invention of an electrical generator that would not consume any fuel. This invention has been lost to the public. Tesla stated about his invention that he had harnessed the cosmic rays and caused them to operate a motive device.

In total, Nikola Telsa was granted more than one hundred patents and invented countless unpatented inventions.

What if quantum physics worked on a macroscopic level?
Quantum physics concerns a world of infinitely small things. But for years, researchers from the University of Geneva (UNIGE), Switzerland, have been attempting to observe the properties of quantum physics on a larger scale, even macroscopic. In January 2011, they managed to entangle crystals, therefore surpassing the atomic dimension. Now, Professor Nicolas Gisin's team has successfully entangled two optic fibers, populated by 500 photons. Unlike previous experiments which were carried out with the fiber optics of one photon, this new feat (which has been published in Nature Physics) begins to answer a fundamental question: can quantum properties survive on a macroscopic level?

Physicists Debate Whether the World Is Made of Particles or Fields--or Something Else Entirely [Preview]

Physicists speak of the world as being made of particles and force fields, but it is not at all clear what particles and force fields actually are in the quantum realm. The world may instead consist of bundles of properties, such as color and shape.

It stands to reason that particle physics is about particles, and most people have a mental image of little billiard balls caroming around space. Yet the concept of “particle” falls apart on closer inspection.
Many physicists think that particles are not things at all but excitations in a quantum field, the modern successor of classical fields such as the magnetic field. But fields, too, are paradoxical.
If neither particles nor fields are fundamental, then what is? Some researchers think that the world, at root, does not consist of material things but of relations or of properties, such as mass, charge and spin.

Anthranilate Fluorescence Marks a Calcium-Propagated Necrotic Wave That Promotes Organismal Death in C. elegans
Abstract

For cells the passage from life to death can involve a regulated, programmed transition. In contrast to cell death, the mechanisms of systemic collapse underlying organismal death remain poorly understood. Here we present evidence of a cascade of cell death involving the calpain-cathepsin necrosis pathway that can drive organismal death in Caenorhabditis elegans. We report that organismal death is accompanied by a burst of intense blue fluorescence, generated within intestinal cells by the necrotic cell death pathway. Such death fluorescence marks an anterior to posterior wave of intestinal cell death that is accompanied by cytosolic acidosis. This wave is propagated via the innexin INX-16, likely by calcium influx. Notably, inhibition of systemic necrosis can delay stress-induced death. We also identify the source of the blue fluorescence, initially present in intestinal lysosome-related organelles (gut granules), as anthranilic acid glucosyl esters—not, as previously surmised, the damage product lipofuscin. Anthranilic acid is derived from tryptophan by action of the kynurenine pathway. These findings reveal a central mechanism of organismal death in C. elegans that is related to necrotic propagation in mammals—e.g., in excitotoxicity and ischemia-induced neurodegeneration. Endogenous anthranilate fluorescence renders visible the spatio-temporal dynamics of C. elegans organismal death.
Author Summary

In the nematode Caenorhabditis elegans, intestinal lysosome-related organelles (or “gut granules”) contain a bright blue fluorescent substance of unknown identity. This has similar spectral properties to lipofuscin, a product of oxidative damage known to accumulate with age in postmitotic mammalian cells. Blue fluorescence seems to increase in aging worm populations, and lipofuscin has been proposed to be the source. To analyze this further, we measure fluorescence levels after exposure to oxidative stress and during aging in individually tracked worms. Surprisingly, neither of these conditions increases fluorescence levels; instead blue fluorescence increases in a striking and rapid burst at death. Such death fluorescence (DF) also appears in young worms when killed, irrespective of age or cause of death. We chemically identify DF as anthranilic acid glucosyl esters derived from tryptophan, and not lipofuscin. In addition, we show that DF generation in the intestine is dependent upon the necrotic cell death cascade, previously characterized as a driver of neurodegeneration. We find that necrosis spreads in a rapid wave along the intestine by calcium influx via innexin ion channels, accompanied by cytosolic acidosis. Inhibition of necrosis pathway components can delay stress-induced death, supporting its role as a driver of organismal death. This necrotic cascade provides a model system to study neurodegeneration and organismal death.

The Physics of Disaster: An Exploration of Train Derailments [Excerpt]

Understanding the science behind trains can help identify the causes of accidents—and lead us to safer railways
http://www.scientificamerican.com/article.cfm?id=the-physics-of-dis...

Everyone knows, or thinks they know, what centrifugal force is. It’s the phenomenon that flings passengers against the car door on a curve, the force that keeps the water in the bucket when swung fast enough overhead, and the force that derails trains on a curve. But centrifugal force can be a source of much confusion because it’s not a force in the traditional sense. Centrifugal force is an inertial effect that occurs when a body in motion changes direction, as in each of the examples above.

Per Isaac Newton, a body in motion tends to stay in motion. If somehow we could eliminate gravity and air resistance, a ball thrown straight up would continue straight up forever. It takes additional force to change the straight-line motion of the ball and to move a train around a curve.

Inertia, the property of matter that resists changes in motion, is most easily explained by accelerating in an elevator. If a 100-lb (0.44-kN) person is standing on a scale in an elevator accelerating up, the scale reads something higher than 100 lbs. If the elevator is accelerating down, the scale reads something less than 100 lbs. If the elevator is accelerating up at 16 ft/sec², or one-half the normal acceleration of gravity, the scale will read 150 lbs (0.66 kN). The extra 50 lbs (0.22 kN) is from the person’s body resisting acceleration.

When a body accelerates, or changes velocity, that acceleration is accompanied by a force. According to Newton’s Second Law, f  m × a. The body’s inertia (m × a) is not a force even though it acts on the scale like a force. The additional 50-lb reading on the scale is the 100-lb person’s resistance to accelerating up 16 ft/sec² (4.9 m/s²)—the person’s inertia.

Inertia always acts in the opposite direction of the acceleration. In the case of the elevator, the person is accelerating up and the inertial response is acting down and is being recorded by the scale. A similar thing happens in circular motion. Circular motion at constant speed creates an acceleration that points toward the center of rotation.

We tend to think of acceleration as being a change in speed (see Chapter 4). Velocity is actually a vector with both direction and magnitude. (The velocity the velocity vector, be it a change in speed or a change in direction, requires a force to create the change. Any change in the velocity vector, be it a change in speed or a change in direction, requires a force to create the change.
