Scientists create Titanium-Gold alloy ~4 times harder than steel

"Titanium is the leading material for artificial knee and hip joints because it's strong, wear-resistant and nontoxic, but an unexpected discovery by Rice University physicists shows that the gold standard for artificial joints can be improved with the addition of some actual gold.

"It is about 3-4 times harder than most steels," said Emilia Morosan, the lead scientist on a new study in Science Advances that describes the properties of a 3-to-1 mixture of titanium and gold with a specific atomic structure that imparts hardness. "It's four times harder than pure titanium, which is what's currently being used in most dental implants and replacement joints."

Has symmetry breaking or "new physics" been found?

"Both possibilities—CP violation or new physics—would have a major impact on the scientific understanding of some of the biggest questions in cosmology."

"(Phys.org)—Over the past few years, multiple neutrino experiments have detected hints for leptonic charge parity (CP) violation—a finding that could help explain why the universe is made of matter and not antimatter. So far, matter-antimatter asymmetry cannot be explained by any physics theory and is one of the biggest unsolved problems in cosmology.

The study: David V. Forero and Patrick Huber. "Hints for Leptonic CP Violation or New Physics?" Physical Review Letters. DOI: https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.117.031801 Also at: http://arxiv.org/abs/1601.03736

Abstract
" One of the major open questions in the neutrino sector is the issue of leptonic CP violation. Current global oscillation data show a mild preference for a large, potentially maximal value for the Dirac CP phase in the neutrino mixing matrix. In this Letter, we point out that new physics in the form of neutral-current-like nonstandard interactions with real couplings would likely yield a similar conclusion even if CP in the neutrino sector were conserved. Therefore, the claim for a discovery of leptonic CP violation will require a robust ability to test new physics scenarios. "

"There is a crack in everything, Leonard Cohen sang; that's how the light gets in. Now a team led by scientists from the National Institute of Standards and Technology (NIST) has explored the properties of a promising class of materials with new capabilities that depend on those cracks. Their results could help open the way for practical applications from nonvolatile computer memory to quick-dimming windows.

The materials in question have been dubbed magneto-ionics—magnetic substances with properties that depend on the arrangement of ions, which are atoms with an electric charge. Computer memory designers like them because they work differently than traditional electronic devices, which depend on the movement of electrons to represent 1s and 0s. But electrons don't stick around in traditional devices when the power dies."

Scientists discover two new objects in resonance with Neptune

"The discovery and characterization of these objects and their orbits are described in the "Beyond the Kuiper Belt edge: New high perihelion Trans-Neptunian Objects with moderate semimajor axes and eccentricities" by Scott S. Sheppard, Chadwick Trujillo, and David J. Tholen, published July 1, 2016 in Astrophysical Journal Letters (Volume 825)."

"The search for distant solar system objects has found two more small worlds far outside the orbit of Neptune. The new objects are located beyond the Kuiper Belt, which is a belt of small icy objects just beyond Neptune, of which Pluto is a member. They have the third and fourth most-distant perihelia, which is when an object has its closest approach distance to the Sun, of any known solar system objects.

They have the third and fourth most-distant perihelia, which is when an object has its closest approach distance to the Sun, of any known solar system objects.

In addition, the orbital motions of these objects are in resonance with Neptune's orbit, which was somewhat unexpected. Their orbital paths imply that these worlds either have interacted with Neptune in the past or are continuing to do so – despite their great distances from the ice giant planet.

This latest discovery is based on observations made with the Subaru Telescope in Hawai'i and Cerro Tololo Inter-American Observatory (CTIO) telescope in Chile, and is described in a paper published in the July 2016 edition of Astrophysical Journal Letters."

Asteroid that formed moon's Imbrium Basin may have been protoplanet-sized

"Around 3.8 billion years ago, an asteroid more than 150 miles across, roughly equal to the length of New Jersey, slammed into the Moon and created the Imbrium Basin—the right eye of the fabled Man in the Moon. This new size estimate, published in the journal Nature, suggests an Imbrium impactor that was two times larger in diameter and 10 times more massive than previous estimates."

Scientists create Titanium-Gold alloy ~4 times harder than steel

"Titanium is the leading material for artificial knee and hip joints because it's strong, wear-resistant and nontoxic, but an unexpected discovery by Rice University physicists shows that the gold standard for artificial joints can be improved with the addition of some actual gold.

"It is about 3-4 times harder than most steels," said Emilia Morosan, the lead scientist on a new study in Science Advances that describes the properties of a 3-to-1 mixture of titanium and gold with a specific atomic structure that imparts hardness. "It's four times harder than pure titanium, which is what's currently being used in most dental implants and replacement joints."

Study: Science Advances, http://advances.sciencemag.org/content/2/7/e1600319

Abstract:
" The search for new hard materials is often challenging, but strongly motivated by the vast application potential such materials hold. Ti3Au exhibits high hardness values (about four times those of pure Ti and most steel alloys), reduced coefficient of friction and wear rates, and biocompatibility, all of which are optimal traits for orthopedic, dental, and prosthetic applications. In addition, the ability of this compound to adhere to ceramic parts can reduce both the weight and the cost of medical components. The fourfold increase in the hardness of Ti3Au compared to other Ti–Au alloys and compounds can be attributed to the elevated valence electron density, the reduced bond length, and the pseudogap formation. Understanding the origin of hardness in this intermetallic compound provides an avenue toward designing superior biocompatible, hard materials. "

Scientists create an "amazing" membrane that resembles organic cells!

"Materials scientists have created a new material that performs like a cell membrane found in nature. Such a material has long been sought for applications as varied as water purification and drug delivery.

Referred to as a lipid-like peptoid (we'll unpack that in a second), the material can assemble itself into a sheet thinner, but more stable, than a soap bubble, the researchers report July 12 in Nature Communications. The assembled sheet can withstand being submerged in a variety of liquids and can even repair itself after damage."

Mars: A crater with a central depression in Noachis Terra | ESA | V3
3D view of crater about 50 kilometers wide in Noachis Terra
These images, acquired by the High Resolution Stereo Camera (HRSC) operated by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) on board the European Mars Express spacecraft show a part of the Noachis Terra region in the southern highlands of Mars. The crater shown is approximately four kilometers deep and has a diameter of roughly 50 kilometers. It has a central depression and drainage valleys at the crater rim. These structures indicate the presence of ice in the subsurface. An unusual dune field reveals that, at present, atmospheric processes shape the landscape.

The, until now unnamed, crater is located southwest of Mare Serpentis, the 'Sea of Serpents', an albedo structure in the Noachis Terra region. Albedo,... more »

These images, acquired by the High Resolution Stereo Camera (HRSC) operated by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) on board the European Mars Express spacecraft show a part of the Noachis Terra region in the southern highlands of Mars. The crater shown is approximately four kilometers deep and has a diameter of roughly 50 kilometers. It has a central depression and drainage valleys at the crater rim. These structures indicate the presence of ice in the subsurface. An unusual dune field reveals that, at present, atmospheric processes shape the landscape.

The, until now unnamed, crater is located southwest of Mare Serpentis, the 'Sea of Serpents', an albedo structure in the Noachis Terra region. Albedo, derived from the Latin word 'alba' for white or bright, is a measure of the reflectivity of surfaces. Dark or rough surfaces reflect less of the incident light than bright or smooth surfaces. Before the space age, the regions of the Moon and Mars with very low or very high albedo values originating from darker or lighter surfaces were identified this way when they were explored by telescope and were then, for example—as in the case of Mare Serpentis—named after seas or lakes because they have a similar albedo.

Approximately 3.9 billion years old, Noachis Terra is amongst the oldest regions of Mars. The Noachian geological era of Mars—covering the period from approximately 4.1 to 3.7 billion years before our time—is also named after this area (Noah's land). Noachis Terra is located in the southern highlands of Mars, west of the large impact basin Hellas Planitia. Numerous impact craters have been formed, altered and degraded in this region over billions of years.

Subsurface ice and rock glaciers in Noachis Terra
The unnamed crater in the images shows a central depression. This type of impact crater is called a 'central pit crater'. They are commonly found on Mars but also occur on Jupiter's moons Ganymede and Callisto. Such a depression in the center of the crater probably arises during or after impact by the vaporization of underground ice which then, due to the sudden explosive expansion of the gas, literally tears a hole in the young crater depression.

The remains of an elevated plateau can be seen to the south and east of the crater. In the past the stacked deposits building the plateau were presumably distributed more uniformly over the area. The loose material was possibly solidified in the vicinity of the crater by the impact and the crater ejecta lay over it like a blanket.

Numerous small valleys and valley networks can be seen on the inner crater rim. Investigations of these valleys and gullies suggest that they were carved out both by meltwater and ice-rich debris flowing downslope. From time to time, the ground ice on the sun-exposed slopes in the interior of the crater melted, and the resulting water flowed towards the center of the crater. The interior of the valleys is filled with ice-rich deposits, referred to as 'lineated valley fill'.

'Air Conditioning' Could Make Exoplanets Habitable

"We built hundreds of computer models to examine this interaction (between the surface of a planet and its atmosphere)," said astronomer Ludmila Carone, of the University of Leuven, in a statement. "In an ideal situation, the cool air is transported from the night to the day side. On the latter side, the air is gradually heated by the star. This hot air rises to the upper layers of the atmosphere, where it is transported to the night side of the planet again."

However, this "ideal situation" can be stymied by strong air currents in the upper atmosphere around the exoplanet's equator that effectively block the flow of hot high-altitude winds from the dayside to nightside hemisphere. This means there is little flow of air from one side to the other, leaving the star-facing hemisphere to bake... more »

But when modeling rocky exoplanets with surfaces that have a high frictional effect on their atmospheres, the situation changes.

Introducing R.O.C.K.Y., the Resistive Overload Combined with Kinetic Yo-Yo device.

"To exercise in Orion beginning on Exploration Mission-2, the first mission of the spacecraft with crew, astronauts will use the Resistive Overload Combined with Kinetic Yo-Yo (ROCKY) device, developed by Zin Technologies of Middleburg Heights, Ohio.

“ROCKY is an ultra-compact, lightweight exercise device that meets the exercise and medical requirements that we have for Orion missions,” said Gail Perusek, deputy project manager for NASA’s Human Research Program’s Exploration Exercise Equipment project. “The International Space Station’s exercise devices are effective but are too big for Orion, so we had to find a way to make exercising in Orion feasible.”"

Bouncing Back

The Universe began with a big bang. Not an explosion from a single point, but rather an early dense state. Of course an obvious question this raises is what came before the big bang? While it’s possible that the answer is “nothing,” that hasn’t stopped some theorists from postulating an earlier cause for the Universe. One of these ideas is known as the big bounce.

The basic idea of the big bounce is that the Universe goes through a series of expansions and contractions. Right now we live in an expanding Universe, but at some point, the model argues, the Universe will start to contract. Eventually it will contract to a dense fireball again, and this will trigger a new big bang. This solves the “what came before” problem of the big bang by postulating an infinite series of big bangs, but it’s not without problems. For one, as we currently understanddark energy t... more »

The Universe began with a big bang. Not an explosion from a single point, but rather an early dense state. Of course an obvious question this raises is what came before the big bang? While it’s possible that the answer is “nothing,” that hasn’t stopped some theorists from postulating an earlier cause for the Universe. One of these ideas is known as the big bounce.

The basic idea of the big bounce is that the Universe goes through a series of expansions and contractions. Right now we live in an expanding Universe, but at some point, the model argues, the Universe will start to contract. Eventually it will contract to a dense fireball again, and this will trigger a new big bang. This solves the “what came before” problem of the big bang by postulating an infinite series of big bangs, but it’s not without problems. For one, as we currently understand dark energy the Universe will likely continue to expand forever. For another, if the Universe did re-collapse into a dense state, we have no idea how it would trigger a new big bang.

A new work in Physical Review Letters proposes a solution to this second problem. The key to the idea is to introduce quantum theory into the mix. In a purely classical model, a shrinking universe will eventually collapse into a singularity. It’s long been thought that quantum theory could provide a solution to this problem, but the devil is in the details. To prevent the formation of a singularity, the work introduces a symmetry known as conformal invariance. As long as the Universe has this symmetry during its dense period, it could enter the dense period at the end of one “universe” and re-expand to form a new “universe.” The authors call this a perfect bounce.

So with the right conditions it’s possible that our Universe could simply be the period between bounces.

This isn’t a flaw of yours in any way, but rather an inevitable feature of special and general relativity. Observers in different locations can never agree on definitions of distance and time, particularly in an expanding Universe. So we invent some alternate definitions for differently scaled types of distance and time: conformal time and comoving distance, to help us understand what’s going on in the Universe.___
