There's nothing quite like renewables: Modeling indicates natural gas production will not reduce future greenhouse gas emissions as hoped

by Jonathan Trinastic in Goodnight Earth

Not so fast natural gas! New modeling using 'commitment' accounting to represent social inertia indicates that natural gas may not reduce emissions as hoped.... Read more »

Wind Turbines Kill Bats by Impersonating Trees

by Elizabeth Preston in Inkfish

Survival tip: don’t hang around machines that have giant spinning blades. It’s a lesson bats have been slow to learn, judging by the large numbers of their corpses found beneath wind turbines. New video footage suggests some bats are attracted to wind farms because they can’t tell turbines apart from trees. If it’s true, this […]The post Wind Turbines Kill Bats by Impersonating Trees appeared first on Inkfish.... Read more »

Are Black Holes just in Our Imagination?!

by Gabriel in Lunatic Laboratories

Black holes, physicists have been fighting over them forever, heck there is even a book entitled the black hole war! (which I do recommend for anyone interested) It’s no real surprise since they are the ultimate unknown – the blackest and most dense objects in the universe that do not even let light escape. And as if they weren't bizarre enough to begin with, now add this to the mix: they don’t exist.... Read more »

Walking Really Is Just Falling and Catching Yourself

by Elizabeth Preston in Inkfish

The flailing of a gymnast who’s missed a step on the balance beam might not be far off from what the rest of us experience every day. Each step we take is really a tiny fall, a mathematical model suggests. The random-looking variation in our footfalls is actually a series of corrections. Our strides are […]The post Walking Really Is Just Falling and Catching Yourself appeared first on Inkfish.... Read more »

DICE 2014

by Marco Frasca in The Gauge Connection

I have spent this week in Castiglioncello participating to the Conference DICE 2014. This Conference is organized with a cadence of two years with the main efforts due to Thomas Elze. I have been a participant to the 2006 edition where I gave a talk about decoherence and thermodynamic limit (see here and here). This […]... Read more »

Should I Stay Or Should I Go

by Mark Lasbury in As Many Exceptions As Rules

Bacteria can swarm to conquer new territory or settle into structured biofilms, not unlike tribes that are nomadic versus those that build cities. New research indicates has shed light on the mechanics of swarming and biofilm production, including the function of extracellular DNA and secreted polysaccharides. Both biofilms and swarming depend on quorum sensing, and several new papers have identified chemicals that can interrupt quorum sensing in pathogenic bacteria and therefore prevent disease........

An efficient magnetic field can exist for light particles

by Usman Paracha in SayPeople

Main Points:

Scientists have opened a new window in science by finding that an effective magnetic field can exist for light.
Published in:

Nature Photonics
Study Further:

Magnetic field refers to the line of forces that are present around the permanent magnet or a moving charged particle. This field can change the path of charged particles such as electrons. Usually, magnetic field has no effect on neutral particles such as photons, which are present in light. However, the present stu........ Read more »

The question of the mass gap

by Marco Frasca in The Gauge Connection

Some years ago I proposed a set of solutions to the classical Yang-Mills equations displaying a massive behavior. For a massless theory this is somewhat unexpected. After a criticism by Terry Tao I had to admit that, for a generic gauge, such solutions are just asymptotic ones assuming the coupling runs to infinity (see here […]... Read more »

Corals Engineer Their Own Currents

by Elizabeth Preston in Inkfish

There are few more monastic lives in the animal kingdom than a coral’s. In adulthood it gives up swimming to settle on the ocean floor, surround its spineless body with clones, and become a rock. Mouth facing the ocean, it waits passively for whatever drifts by—or maybe not so passively. Taking a closer look at […]The post Corals Engineer Their Own Currents appeared first on Inkfish....

Falsifiability and Gandy’s variant of the Church-Turing thesis

by Artem Kaznatcheev in Evolutionary Games Group

In 1936, two years after Karl Popper published the first German version of The Logic of Scientific Discovery and introduced falsifiability; Alonzo Church, Alan Turing, and Emil Post each published independent papers on the Entscheidungsproblem and introducing the lambda calculus, Turing machines, and Post-Turing machines as mathematical models of computation. The years after saw many […]... Read more »

Whitman Was Not a Neuroscientist

by The Neurocritic in The Neurocritic

Do I contradict myself?Very well then I contradict myself,(I am large, I contain multitudes.)-Walt Whitman, "Song of Myself" (from Leaves of Grass)Science is the search for objective truth based on physical laws of the universe. Scientific theories try to explain the consistent and predictable behavior of natural systems. They are generally reductionist, meaning that complex systems are reduced to simpler and more fundamental elements. The principles of physics, for instance, are expressed in th........ Read more »
