Researchers on Thursday said they conducted experiments to learn precisely how sidewinder rattlesnakes are able to climb sandy hills, then applied the reptiles’ repertoire to an existing snake robot so it could do the same thing. (Credit: Chaohui Gong, Reuters/Chaohui Gong)

Results confirm the time dilation predicted for high velocities in the theory of relativity with an accuracy that has never before been achieved. Furthermore, the team provided the first direct proof of a spectral line in highly charged bismuth ions. (Credit: Technische Universität Darmstadt )

The Hubble Space Telescope has imaged light from a hot Jupiter called WASP-43b, detecting temperature differences between the planet’s day and night sides. The results suggest that the planet has an eastward jet stream that redistributes some of the heat from its host star, but otherwise there’s very little circulation of heat. (Credit: Hubble, Timmer)

If you ever wanted to see a sci-fi plot that expertly applied advanced physical concepts so that with a bit of imagination teleporting a human was not as unbelievable as most of the teleportation scenarios we see in the movies, read this article. The above is a Cosmic Treadmill, as it appears in Flash #196. (Credit: Paul Winslade, Hmmmjenia)

Astronomers have found a pulsating dead star beaming with the energy of about 10 million Suns, which is the brightest pulsar ever recorded.. A rare and mighty pulsar (pink) can be seen at the center of galaxy M82 in this new multi-wavelength portrait. NASA’s NuSTAR mission discovered the “pulse” of the pulsar — a type of dead star — using is high-energy X-ray vision.

The term Higgsogenesis refers to the first appearance of Higgs particles in the early universe, just as baryogenesis refers to the appearance of baryons (protons and neutrons) in the early moments after the big bang. While baryogenesis is a fairly well understood process, Higgsogenesis is still very hypothetical. (Credit: CERN/Lucas Taylor, Koberlein)

A new measurement of dark matter in the Milky Way has revealed there is half as much of the mysterious substance as previously thought. The above is an artist’s impression of the Milky Way and its dark matter halo (shown in blue, but in reality invisible). (Credit: ESO/L. Calçada)

After a couple of years of racing towards Mount Sharp (Aeolis Mons), now it’s time for the Curiosity rover to get a better look at its Martian surroundings. Rover tracks and Martian sand as seen from the rear hazcam of NASA’s Curiosity rover. (Credit: NASA/JPL-Caltech)

Two new particles have been discovered by the LHCb experiment at CERN’s Large Hadron Collider near Geneva, Switzerland. One of them has a combination of properties that has never been observed before. (Credit: Dave Stock)

The image above shows a graphic which was produced by the SETI from the data of the Wow signal. A signal (Gaussian, triplet or pulse) arises only in a single narrowband channel. All other channels contain noise. Up to now we do not know cosmic phenomena which would generate such signals. It would seem improbable that they have no artificial origin. The picture shows a computer generated example of a strong Gaussian signal.

This quirk of subatomics could have huge implications for our understanding of the universe, specifically how the current inequality between matter and antimatter came to be. Answering that could, in turn, provide a better insight as to why reality did not simply blink out of existence immediately after the Big Bang as a universe’s worth of matter and antimatter negated one another’s existences (Credit: Tarantola, Fermilab, )

Agravity, short for ‘adimensional gravity’, is one of the most recent Theory of Everything proposals in a long line of such proposals that have come about ever since the problem of reconciling Gravity with the Standard Model was realized by physicists. It attempts to merge gravity with the Higgs interaction, and thus the rest of the Standard Model, by reconciling the huge difference between the Planck Scale and the relatively small masses of all the other particles.

The decision to reformat Opportunity’s flash memory early next month is prompted by the multiple computer resets the rover has been experiencing. This month alone, Opportunity has had to be rebooted a dozen times, interrupting valuable time that should be taken up with carrying out science near the rim of Endeavour crater.

“It’s fascinating that the early universe could make galaxies in this way and the modern universe just can’t anymore, and we’re really beginning to understand in a profound way how different the early universe was than it is now,” said Erica Nelson of Yale University. (Credit: Neslson)

This is a scanning electron microscope image of an interplanetary dust particle that has roughly chondritic elemental composition and is highly rough (chondritic porous: “CP”). CP types are usually aggregates of large numbers of sub-micrometer grains, clustered in a random open order. (Credit: Donald E. Brownlee)

Inflation explains the origin of the large-scale structure of the cosmos. Many physicists believe that inflation explains why the Universe appears to be the same in all directions (isotropic), why the cosmic microwave background radiation is distributed evenly, why the universe is flat, and why no magnetic monopoles have been observed.

Engineers just completed hot-fire testing with two 3-D printed rocket injectors. Certain features of the rocket components were designed to increase rocket engine performance. The injector mixed liquid oxygen and gaseous hydrogen together, which combusted at temperatures over 6,000 degrees Fahrenheit, producing more than 20,000 pounds of thrust.
