How stem cells create just enough tissue

Scientists have long wondered just how stem cells generate just the right amount of tissue to perform a biological function. Using live imaging of skin of living mice, Yale scientists have shown that this balance, called homeostasis, is achieved in unexpected ways. In the accompanying movie, the researchers—led by Panteleimon Rompolas and Kailin R. Mesa in the lab of Valentina Greco—captured images of how stem cells (in red) at the bottom layer of epidermis (green) line up in columns and enlarge to replace cells lost at the top layer of skin.

Giant Tsunamis Battered the Coastlines of an Early Martian Ocean

New +NASA-funded research indicates that giant tsunamis played a fundamental role in forming #Martian coastal terrain, removing much of the controversy that for decades shrouded the hypothesis that oceans existed early in #Mars’ history.

It is now widely accepted by the Mars research community that approximately 3.4 billion years ago, an extremely cold and dry desert existed at the surface of Mars‬, while enormous subsurface aquifers overlain by ice-rich permafrost retained most of the water on the Red Planet. Researchers think that, at that time in the planet’s history, several large aquifers catastrophically ruptured, carving large outflow channels and flooding Mars’ northern plains to form an ocean.

Giant Tsunamis Battered the Coastlines of an Early Martian Ocean

New +NASA-funded research indicates that giant tsunamis played a fundamental role in forming #Martian coastal terrain, removing much of the controversy that for decades shrouded the hypothesis that oceans existed early in #Mars’ history.

It is now widely accepted by the Mars research community that approximately 3.4 billion years ago, an extremely cold and dry desert existed at the surface of Mars‬, while enormous subsurface aquifers overlain by ice-rich permafrost retained most of the water on the Red Planet. Researchers think that, at that time in the planet’s history, several large aquifers catastrophically ruptured, carving large outflow channels and flooding Mars’ northern plains to form an ocean. However, an apparent lack of definite shoreline features made this uncertain. This new research shows that the shorelines exist below the present surface and were modified and buried by two mega-tsunami events.

A key implication of the study is that the tsunami deposits can be used to reconstruct the evolution of the Martian climate during the lifetime of the ocean, and the younger deposits likely contain ice remnants from the ancient ocean itself.

The researchers believe the ocean floor might have provided habitable environments, if the ocean persisted long enough. The fine-grained ‎Martian‬ tsunami deposits could have preserved physical or chemical evidence of past microbial activity, if it existed.

NASA Radar Finds Ice Age Record in Mars' Polar Cap

NASA Radar Finds Ice Age Record in Mars' Polar Cap
Climatic cycles of ice and dust build the Martian polar caps.
By analyzing radar images like the one at top of this montage, scientists discovered evidence for a past ice age in the northern polar ice cap of Mars.

Scientists using radar data from NASA's Mars Reconnaissance Orbiter (MRO) have found a record of the most recent Martian ice age recorded in the planet's north polar ice cap.

The new results agree with previous models that indicate a glacial period ended about 400,000 years ago, as well as predictions about how much ice would have been accumulated at the poles since then.

The results, published in the May 27, 2016 issue of the journal Science, help refine models of the Red Planet's past and future climate by allowing scientists to determine how ice moves between the poles and mid-latitudes, and in what volumes.

Mars has bright polar caps of ice that are easily visible from telescopes on Earth. A seasonal cover of carbon-dioxide ice and snow is observed to advance and retreat over the poles during the Martian year. During summertime in the planet's north, the remaining northern polar cap is all water ice; the southern cap is water ice as well, but remains covered by a relatively thin layer of carbon dioxide ice even in southern summertime.

But Mars also undergoes variations in its tilt and the shape of its orbit over hundreds of thousands of years. These changes cause substantial shifts in the planet's climate, including ice ages. Earth has similar, but less variable, phases called Milankovitch cycles.

Scientists use data from MRO's Shallow Subsurface Radar (SHARAD) to produce images called radargrams that are like vertical slices though the layers of ice and dust that comprise the Martian polar ice deposits. For the new study, researchers analyzed hundreds of such images to look for variations in the layer properties.

The researchers identified a boundary in the ice that extends across the entire north polar cap. Above the boundary, the layers accumulated very quickly and uniformly, compared with the layers below them.

"The layers in the upper few hundred meters display features that indicate a period of erosion, followed by a period of rapid accumulation that is still occurring today," said planetary scientist Isaac Smith, the study's lead author. Smith led the work while at Southwest Research Institute in Boulder, Colorado, but is now at the Planetary Science Institute in Tucson, Arizona.

On Earth, ice ages take hold when the polar regions and high latitudes become cooler than average for thousands of years, causing glaciers to grow toward the mid-latitudes. In contrast, the Martian variety occurs when—as a result of the planet's increased tilt—its poles become warmer than lower latitudes. During these periods, the polar caps retreat and water vapor migrates toward the equator, forming ground ice and glaciers at mid-latitudes. As the warm polar period ends, polar ice begins accumulating again, while ice is lost from mid-latitudes. This retreat and regrowth of polar ice is exactly what Smith and colleagues see in the record revealed by the SHARAD radar images.

An increase in polar ice following a mid-latitude ice age is also expected from climate models that show how ice moves around based on Mars' orbital properties, especially its tilt. These models predict the last Martian ice age ended about 400,000 years ago, as the poles began to cool relative to the equator. Models suggest that since then, the polar deposits would have thickened by about 980 feet (300 meters).

The upper unit identified by Smith and colleagues reaches a maximum thickness of 1,050 feet (320 meters) across the polar cap, which is equivalent to a 2-foot-thick (60-centimeter-thick) global layer of ice. That is essentially the same as model predictions made by other researchers in 2003 and 2007.

"This suggests that we have indeed identified the record of the most recent Martian glacial period and the regrowth of the polar ice since then. Using these measurements, we can improve our understanding of how much water is moving between the poles and other latitudes, helping to improve our understanding of the Martian climate," Smith said.

After 10 years in orbit, Mars Reconnaissance and its six science instruments are still in excellent shape. "The longevity of the mission has enabled more thorough and improved radar coverage of the Martian poles," said Richard Zurek, the mission's project scientist at NASA's Jet Propulsion Laboratory, Pasadena, California. "Our long life in orbit and powerful 3-D analysis tools are allowing scientists to unravel Mars' past climate history."

Image Description: This image montage features a two-dimensional radar cross section of Mars' north polar cap collected by SHARAD instrument on NASA's Mars Reconnaissance Orbiter spacecraft (top), and a color image mosaic of the polar cap from NASA's Viking project (bottom)

By analyzing radar images like the one at top, scientists discovered evidence for a past ice age in the northern polar ice cap of Mars.

The top 330 to 980 feet (100 to 300 meters) of layered ice in the polar deposits reveal a stark change in properties between layers representing an ice age and a subsequent inter-glacial period.

In the radar image, layers below the blue line show migration of spiral features in the polar cap, toward the left. Above the blue line, those features disappear or reverse their migration direction—an indication of changes in accumulation rate and wind patterns associated with climate change. In other regions of the polar cap, the blue line is associated with widespread erosion—an event that corresponded with an ice age.

A blue line across the Viking map indicates the ground track of the radar cross section. Vertical height in the radar image has been exaggerated to improve the visibility of the layers.

SHARAD was provided by the Italian Space Agency. Its operations are led by Sapienza University of Rome, and its data are analyzed by a joint U.S.—Italian science team. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter for the NASA Science Mission Directorate, Washington. Lockheed Martin Space Systems, Denver, built the spacecraft.

Hear, hear: Astronomers find giant planet around very young star!

"In contradiction to the long-standing idea that larger planets take longer to form, U.S. astronomers today announced the discovery of a giant planet in close orbit around a star so young that it still retains a disk of circumstellar gas and dust.

"For decades, conventional wisdom held that large Jupiter-mass planets take a minimum of 10 million years to form," said Christopher Johns-Krull, the lead author of a new study about the planet, CI Tau b, that will be published in the Astrophysical Journal. "That's been called into question over the past decade, and many new ideas have been offered, but the bottom line is that we need to identify a number of newly formed planets around young stars if we hope to fully understand planet formation."

Hear, hear: Astronomers find giant planet around very young star!

"In contradiction to the long-standing idea that larger planets take longer to form, U.S. astronomers today announced the discovery of a giant planet in close orbit around a star so young that it still retains a disk of circumstellar gas and dust.

"For decades, conventional wisdom held that large Jupiter-mass planets take a minimum of 10 million years to form," said Christopher Johns-Krull, the lead author of a new study about the planet, CI Tau b, that will be published in the Astrophysical Journal. "That's been called into question over the past decade, and many new ideas have been offered, but the bottom line is that we need to identify a number of newly formed planets around young stars if we hope to fully understand planet formation."

CI Tau b orbits the star CI Tau once every nine days. The planet was found with the radial velocity method, a planet-hunting technique that relies upon slight variations in the velocity of a star to determine the gravitational pull exerted by nearby planets that are too faint to observe directly with a telescope. The discovery resulted from a survey begun in 2004 of 140 candidate stars in the star-forming region Taurus-Auriga.

"This result is unique because it demonstrates that a giant planet can form so rapidly that the remnant gas and dust from which the young star formed, surrounding the system in a Frisbee-like disk, is still present," said Lisa Prato of Lowell Observatory, co-leader of the young planet survey and a co-author on the paper. "Giant planet formation in the inner part of this disk, where CI Tau b is located, will have a profound impact on the region where smaller terrestrial planets are also potentially forming."

Evidence for a new boson and more forces?
Ever since the discovery of dark matter and the inability of the standard model of particle physics to explain it (and the failure to detect WIMPs), dark forces mediated by new bosons and involving hidden sectors have got increasing attention. Key to extending the standard model is to find phenomena that deviate from its predictions.
Scientists in Hungary fired protons at Lithium targets and studied the angular distribution of electron-positron pairs emitted by unstable Be-8 nuclei formed when proton hits Li-7. They found an unexpected bump at 140 degrees angular separation which should not have been there if the standard model is all there is to it suggesting the presence of new interactions and particles. While the experimenters have ruled out instrument error, theorists are scrambling with new theoretical explanations and other teams are... more »

While the experimenters have ruled out instrument error, theorists are scrambling with new theoretical explanations and other teams are planning to look at a new 17MeV boson which is the simplest explanation with the data. It turns out that currently available experimental data does not rule out the possibility.___

The Heat of the Night

The Universe is filled with a sea of radiation. Theres a background of light created by various cosmic processes. The most famous is the cosmic microwave background, but there are other cosmic backgrounds such as the x-ray background and infrared background. That last one is notoriously difficult to observe.

In principle measuring a background should be pretty easy. Just look for those particular wavelengths of light in all directions. The problem is that in addition to any background signal there are also lots of things that produce those wavelengths directly, known as the foreground. Separating the foreground from the background is always a challenge. When the BICEP2 debacle occurred, the debate centered on whether BICEP2 had actually detected an effect of the cosmic microwave background, or whether it was noise from foreground objects.

Separating the foreground from the background is always a challenge. When the BICEP2 debacle occurred, the debate centered on whether BICEP2 had actually detected an effect of the cosmic microwave background, or whether it was noise from foreground objects. It turned out to be the latter. The foreground effect is such a challenge for the infrared background because so many things produce infrared light. If something is “warm” it’s radiating in the infrared.

Much of the infrared background comes from distant galaxies. As the light of a galaxy’s stars strike gas and dust it warms them, causing an emission of infrared light. Quasars can also add to the infrared background, when the x-rays and gamma rays collide with gas and dust, and that energy is re-emitted as infrared. Just like the cosmic microwave background has small variations in temperature and brightness, the cosmic infrared background also varies slightly. Since these two backgrounds have different sources and were emitted at different times in the history of our Universe, comparing them provides clues about the evolution of the early Universe. It could even provide clues about dark matter and dark energy.

“Sure, it’s not 100% ruled out that black holes of around 30 solar masses could be the dark matter, but it’s far from the most likely explanation. In physics, as in life, the smart money is to bet on what’s already known as the most likely explanation for the novel phenomenon we just saw. While the more fanciful possibilities might spark our imagination, they’re also most likely wrong.”

Dark matter is one of the biggest mysteries in the Universe. We can feel its gravitation, we can see its effects on galaxies, clusters and the large-scale structure of the Universe. But when it comes to very small scales, we haven’t been able to detect dark matter, either directly or indirectly, leading us to wonder at what it’s mysterious nature might be.

While the notion that primordial black holes could be the dark matter has been disfavored by a large suite of observations, the LIGO detection of two merging black holes – of a particular, unusual mass – has rekindled interest in that nearly-abandoned idea. Could the fluctuations in the cosmic infrared background actually be due to these primordial black holes, and could they make up 100% of the dark matter?

The answer is almost definitely “no,” and here’s the scoop as to why!___

Visiting the L4 Trojan Asteroid (624) Hektor

Today let’s watch (624) Hektor, the binary and bilobed largest Jupiter-Trojan asteroids. This is a puzzling multiple asteroid system with a lot of mysteries (eccentric and inclined orbit of the moon, complex shape and structure for the primary, etc.).

Our study based on AO observations collected over 8 years was published in 2014. The conclusion of our work is that 624 Hektor is probably a captured Kuiper-belt object and the moon formed a long time ago from the slow velocity encounter of the components.
