List LangShan Technology  ening to the Sound of Big Bang

The Planck satellite mission mapped light temperature differences on the oldest surface known — the background sky left billions of years ago when our universe first became transparent to light. Those differences helped to recreate the sound of the Big Bang. European Space Agency/Planck Collaboration

Using ne Industrial 3G Router  w data from the ESA’s Planck Mission analysis of the CMB, physicist John Cramer from the University of Washington provides a new “high-fidelity” rendition of the Sound of the Big Bang.

A decade ago, spurred by a question for a fifth-grade science project, University of Washington physicist John Cramer devised an audio recreation of the Big Bang that started our universe nearly 14 billion years ago.

Now, armed with more sophisticated data from a satellite mission observing the cosmic microwave background – a faint glow in the universe that acts as sort of a fossilized fingerprint of the Big Bang – Cramer has produced new recordings that fill in higher frequencies to create a fuller and richer sound. (The sound files run from 20 seconds to a little longer than 8 minutes.)

The effect is similar to what seismologists describe as a magnitude 9 earthquake causing the entire planet to actually ring. In this case, however, the ringing covered the entire universe – before it grew to such gargantuan proportions.

“Space-time itself is ringing when the universe is sufficiently small,” Cramer said.

In 2001, Cramer wrote a science-based column for Analog Science Fiction & Fact magazine describing the likely sound of the Big Bang based on cosmic microwave background radiation observations taken from balloon experiments and satellites.

A couple of years later that article prompted a question from a mother in Pennsylvania whose 11-year-old son was working on a project about the Big Bang: Is the sound of the Big Bang actually recorded anywhere?

Cramer answered that it wasn’t – but then began thinking that it could be. He used data from the cosmic microwave background on temperature fluctuations in the very early universe. The data on those wavelength changes were fed into a computer program called Mathematica, which converted them to sound. A 100-second recording represents the sound from about 380,000 years after the Big Bang until until aboutmulti SIM LTE router 760,000 years after the Big Bang.

“The original sound waves were not temperature variations, though, but were real sound waves propagating around the universe,” he said.

Cramer noted, however, that the 2003 data lacked high-frequency structure. More complete data were recently gathered by an international collaboration using the European Space Agency’s Planck satellite mission, which has detectors so sensitive that they can distinguish temperature variations of a few millionths of a degree in the cosmic microwave background. That data were released in late March and led to the new recordings.

Planck Multipole Spectrum

As the universe cooled and expanded, it stretched the wavelengths to create “more of a bass instrument,” Cramer said. The sound gets lower as the wavelengths are stretched farther, and at first it gets louder but then gradually fades. The sound was, in fact, so “bass” that he had to boost the frequency 100 septillion times (that’s a 100 followed by 24 more zeroes) just to get the recordings into a range where they can be heard by humans.

Cramer is a UW physics professor who has been part of a large collaboration studying what the universe might have been like moments after the Big Bang by causing collisions between heavy ions such as gold in the Relativistic Heavy Ion Collider at Brookhaven National Laboratory in New York.

Creating a sound profile for the Big Bang was something to do on the side, Cramer said.

“I 4G Network Migrationt was an interesting thing to do that I wanted to share. It’s another way to look at the work these people are doing,” he said.

Middle Stone Age Innovation Linked to Rapid Climate wordpress   Change

A newly published study presents the most convincing evidence so far that abrupt climate change was instrumental in the development human evolution.

Rapid climate change during the Middle Stone Age, between 80,000 and 40,000 years ago, during the Middle Stone Age, sparked surges in cultural innovation in early modern human populations, according to new research.

The research, published in the journal Nature Communications, was conducted by a team of scientists from Cardiff University’s School of Earth and Ocean Sciences, the Natural History Museum in London and the University of Barcelona.

The scientists studied a marine sediment core off the coast of South Africa and reconstructed terrestrial climate variability over the last 100,000 years.

Dr Martin Ziegler, Cardiff University School of Earth and Ocean Sciences, said: “We found that South Africa experienced rapid climate transitions toward wetter conditions at times when the Northern Hemisphere experienced extremely cold conditions.”

These large Northern Hemisphere cooling events have previously been linked to a change in the Atlantic Ocean circulation that led to a reduced transport of warm water to the high latitudes in the North. In response to this Northern Hemisphere cooling, large parts of the sub-Saharan Africa experienced very dry conditions.

“Our new data however, contrasts with sub-Saharan Africa and demonstrates that the South African climate responded in the opposite direction, with increasing rainfall, that can be associated with a global UMTS router  ly occurring southward shift of the tropical monsoon belt.”

Linking climate change with human evolution

Professor Ian Hall, Cardiff University School of Earth and Ocean Sciences, said: “When the timing of these rapidly occurring wet pulses was compared with the archaeological datasets, we found remarkab Industrial IoT Connectivity  le coincidences.

“The occurrence of several major Middle Stone Age industries fell tightly together with the onset of periods with increased rainfall”

“Similarly, the disappearance of the industries appears to coincide with the transition to drier climatic conditions.”

Professor Chris Stringer of London’s Natural History Museum commented “The correspondence between climatic ameliorations and cultural innovations supports the view that population growth fueled cultural changes, through increased human interactions”.

The South African archaeological record is so important because it shows some of the oldest evidence for modern behavior in early humans. This includes the use of symbols, which has been linked to the development of complex language, and personal adornments made of seashells.

“The quality of the southern African data allowed us to make these correlations between climate and behavioral change, but it will require comparable data from other areas before we can say whether this region was uniquely important in the development of modern human culture” added Professor Stringer.

The new study presents the most convincing evidence so far that abrupt climate change was instrumental in this development.

The research was supported by the UK Natural Environment Research Council and is part of the international Gateways training network, funded by the 7th Framework Program of the European Union.

Study Shows Stem Cell Injections Improve Spinal Injuries in R openvpn  ats

A team of scientists are reporting in a new study that a single injection of human neural stem cells, which came from a line of human embryonic stem cells recently approved for Phase 1 human trials in patients with chronic traumatic spinal injuries, produced neuronal regeneration and improvement of function and mobility in rats impaired by an acute spinal cord injury.

An international team led by researchers at the University of California, San Diego School of Medicine reports that a single injection of human neural stem cells produced neuronal regeneration and improvement of function and mobility in rats impaired by an acute spinal cord injury (SCI).

The findings are published in the May 28, 2013 online issue of Stem Cell Research & Therapy.

Martin Marsala, MD, professor in the Department of Anesthesiology, with colleagues at UC San Diego and in Slovakia, the Czech Republic and The Netherlands, said grafting neural stem cells derived from a human fetal spinal cord to the rats’ spinal injury site produced an array of therapeu computer  tic benefits – from less muscle spasticity to new connections between the injected stem cells and surviving host neurons.

“The primary benefits were improvement in the positioning and control of paws during walking tests and suppression of muscle spasticity,” said Marsala, a specialist in spinal cord trauma and spinal injury-related disorders. Spasticity – exaggerated muscle tone or uncontrolled spasms – is a serious and common complication of traumatic injury to the spinal cord.

The human stem cells, said the scientists, appeared to vigorously take root at the injury site.

“In all cell-grafted animals, there was robust engraftment, and neuronal maturation of grafted human neurons was noted,” Marsala said. “Importantly, cysts or cavities that can form in or around spinal injuries were not present in any cell-treated animal. The injury-caused cavity was completely filled by grafted cells.”

The rats received the pure stem cell grafts three days after injury (no other supporting materials were used) and were given drugs to suppress an immune response to the foreign stem cells. Marsala said grafting at any time after the injury appears likely to work in terms of blocking the formation of spinal injury cavities, but that more work would be required to determine how timing affects functional neurological benefit.

The grafted stem cells, according to Marsala, appear to be doing two things: stimulating host neuron regeneration and partially replacing the function of lost neurons.

“Grafted spinal stem cells are rich source of different growth factors which can have a neuroprotective effect and can promote sprouting of nerve fibers of the host neurons. We have also demonstrated that grafted neurons can develop contacts with the host neurons and, to some extent, restore the connectivity between centers, above and below the injury, which are involved in motor and sensory processing.”

The scientists used a line of human embryonic stem cells recently approved for Phase 1 human trials in patients with chronic traumatic spinal injuries. Marsala said the ultimate goal is to develop neural precursor cells (capable of becoming any of the three main cell types in the nervous system) from induced pluripotent stem cells derived from patients, which would likely eliminate the need for immunosuppression treatment.

Pending approval by UC San Diego’s Institutional Review Board, the next step is a small phase 1 trial to test safety and efficacy with patients who have suffered a thoracic spinal cord injury (between vertebrae T2-T12) one to two years earlier, and who have no motor or sensory function at or below the spinal injury site.

“This is exciting, especially because, historically, there has been very little to offer patients with acute spinal cord injury,” said study co-author Joseph Ciacci, MD, professor of surgery and program director of the Neurosurgery Residency at the UC San Diego School of Medicine. Ciacci, who is also chief of neurosurgery for the Veterans Affairs San Diego Healthcare System, will oversee the clinical trial at UC San Diego and the VA.

Ciacci said if the initial study confirms safety and efficacy, as well as theiot ve industrial cellular modem  nding machine viability of the implanted cells, neural regeneration and decreased spasticity, the protocol can be expanded to other patients with other forms of severe spinal cord injury.

Children w InHand Networks - Global Leader in Industrial IoT  ith Cochlear Implants Learn Words Faster Than Children With Normal Hearing

www.inhandnetworks.com

According to estimates by the Robert Koch Institute, up to two thousand hearing impaired children are born in Germany each year. For some of them a cochlear implant can offer relief. Until now, it was not clear which processes take place in the affected children when they start to learn language later than their contemporaries with normal hearing—and why they differ 4g router  in their success to reach a normal level of language. A current study at the Max Planck Institute for Human Cognitive and Brain Sciences (MPI CBS) in Leipzig and University Medical Centre Dresden found that deaf children with a cochlear implant learn words even faster than those with normal hearing. This finding can help refine the search for the reasons behind their varying success in language acquisition.

For many years scientists tinkered to find a perfect replacement for the damaged or dysplastic inner ear. Cochlear implants receive a sound, convert it into electrical stimuli and send these impulses directly to the auditory nerve, thereby giving deaf children the chance to connect to the world of sounds and noises.

It has so far been assumed that these children reach the language level of hearing children much later. Previous studies showed that from the moment of having the device implanted, children need longer to attain the important steps of learning their mother tongue—for instance, being able to distinguish the rhythm of their mother tongue from that of another language. This could imply that developmental milestones necessary to start school are also delayed, although they reach all the other developmental stages needed.

Deaf children with cochlear implants benefit from their older age

A current study at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig and the University Medical Centre Dresden has now revealed something different: “We observed that when deaf children get their implants, they learn words faster than those with normal hearing. Consequently, they build up certain word pools faster”, says Niki Vavatzanidis, first author of the underlying study and scientist at MPI CBS and the University Medical Centre Dresden. Normally, children need fourteen months to reliably recognise that known objects are named incorrectly. Children with an artificial cochlea were already able to do so after twelve months.

The reason for this finding could be that children with cochlear implants are older when they are first exposed to spoken language. Those with normal hearing learn cashless vendingaspects of language, such as the rhythm and melody of their mother tongue, from birth and even in the womb. In deaf children, this only starts at the time of their cochlear replacement, at the age of around one to four years. By this time certain brain structures necessary for language acquisition are already well developed. “It is not just the memory, but also the broader knowledge about their surroundings that is more formed. They already know about objects in their environment and have accumulated non-linguistic semantic categories” states Vavatzanidis. For example, they already know that objects such as cups or meals could be hot and that heat could be something harmful without knowing the word “hot”.

Recording electrical brain activity

The neuroscientists examined these relations with the help of thirty-two children with cochlear implant in both ears. They carried out a test after twelve, eighteen and twenty-four months after implantation that tested their ability to recognise words: The young study participants were shown pictures of objects which were named either correctly or incorrectly. In parallel to this, the scientist analysed the brain activities of the little ones using electroencephalography (EEG). If the researchers detected an effect in the EEG known as N400, they knew that the child registered the incorrect word. This means they had established a stable connection between objects and their names. They had learnt the word.

“Children with cochlear implants could help us understand the general processes of language acquisition and determine which single steps are age-dependent” Angela D. Friederici explains, study leader and head of MPI CBS. “We now know that age does not affect how IIoT   fast children learn words. On the contrary, they seem to catch up even if they were previously disadvantaged.” Upcoming studies should now focus on why some of the affected children, despite these findings, struggle to reach the level of their contemporaries with normal hearing.

Microbial Continental Ecosystems Help medium voltage smart grid sensor  ed Seed Ancient Seas

The new study suggests these biocrusts played a vital role in the nitrogen cycle of the early earth. Credit: Estelle Couradeau

Like our oceans, today’s continents are brimming with life. Yet billions of years ago, before the advent of plants, continents would have appeared barren. These apparently vacant land forms were believed to play no role in the early biochemical clockwork known as the nitrogen cycle, which most living things depend on for survival.

Now, ASU researcher Ferran Garcia-Pichel, along with Christophe Thomazo, from the Laboratoire Biogéosciences in Dijon, France, and Estelle Couradeau, a former Marie Curie Postdoc in both labs, show that biological soil crusts–colonies of microorganisms that today colonize arid, desert environments–may have played a significant role in the Earth’s nitrogen cycle, helping to fertilize early oceans and create a nutrient link between atmosphere, continents and oceans.

Garcia-Pichel directs the Biodesign Center for Fundamental and Applied Microbiomics and is a professor in ASU’s School of Life Sciences.  iiot  Originally, a marine microbiologist, he became fascinated with the hidden world of microorganisms that lay on top of soils in deserts and other arid regions devoid of plant life. These living biocrusts have remarkable properties, thriving in extreme conditions, helping to anchor soils in place, so they resist erosion, and fertilizing rangelands and deserts.

The new research, which appears in the advanced online edition of the journal Nature Communications, suggests that analogs of these biocrusts spread across otherwise desolate continents of the early Earth, and contributed to establishing the nitrogen cycle essential for life as we know it today.

Evolving atmosphere

“This really early Earth was a very different planet in many respects, particularly in the composition of the atmosphere,” Garcia-Pichel says. “Before the appearance of oxygenic photosynthetic microbes, like cyanobacteria that made oxygen–just like plants do today–the atmosphere was not oxygenated.” This vast oxygen-free epoch lasted for half of Earth’s 4.6 billion year history.

All this changed with something referred to by geochemists as the Great Oxygenation Event. “That was perhaps the single most important change in the nature of what the planet is. There are telltale signs of this in the rock record, so people have a good idea of when this happened–around 2.45 billion years ago,  industrial LTE router  but conventional wisdom would have this happening in shallow oceans” Garcia-Pichel says.

Today, nitrogen makes up 78 percent of the atmosphere. It is a vital element in DNA, RNA and proteins, the key components of life. But the nitrogen found in the atmosphere is not suitable for use by most organisms. It must first be processed, through what is known as the nitrogen cycle. This occurs when prokaryotic organisms carry out nitrogen fixation, making atmospheric nitrogen available in a form useful to plants and animals for survival.

While it has long been assumed that the nitrogen cycle that arose early in the Earth’s history, resulted from oceanic microbes during an ancient phase known as the Archean, new research suggests significant amounts of nitrogen came from land-based biological soil crusts.

Shifting perspective

“In the minds of many evolutionary biologists, the continents were irrelevant early in the Earth’s history, because they are assumed to have been barren of life until the first plants appeared, around 0.4 billion years ago. So all the models of how elements were cycled were based on interactions between the ocean and the atmosphere,” Garcia-Pichel says.

Recently however, evidence began to appear suggesting that the continents were far from the sterile land masses they had been portrayed as. Instead, intricate microbial communities similar to biocrusts found in present-day desert environments, colonized the early continents. Traces of their presence date to 3.2 billion years ago, well before the Great Oxygenation Event helped set the stage for the Cambrian explosion–a sudden burst of life that gave rise to most of the world’s animal phyla.

The researchers note that today, such biocrusts occupy roughly 12 percent of the Earth’s land. They are composed of filamentous cyanobacteria, which perform most of the biocrust’s carbon and nitrogen fixation and provide nutrients to the rest of the crust microbiome, while bonding soil grains together and providing microbial communities with erosion resistance.

“These communities live on light,” Garcia-Pichel says. “When plants evolved and started to accumulate, this marked their demise. There’s no light on the soil anymore because of plant litter accumulation”. However, in an early world, before the evolution of plants, there would be nothing to impede their colonization of the continents, where conditions for their growth and development would have been considerably less harsh.

As Garcia-Pichel notes, watery environments like oceans and lakes provide superior conditions for fossilization, making the detection of ancient biocrust colonies on land more challenging. This may account in part for the neglect of continental biocrusts as the primeaval land-based ecosystems for much of the planet’s history.

A new picture emerges

The team carried out a meta-analysis of their earlier data combined with other relevant literature on the cycling of nitrogen by modern biocrusts. Results demonstrate that nitrogen-cycling biocrusts are capable of importing nitrogen gas from the atmosphere and exporting ammonium and nitrate.

Quantitative analysis suggests that biocrust contribution to nitrogen cycling during the early history of the Earth would have been significant, even with limited colonization of the pre-Cambrian continents.

The notion of land-based life forms–the biocrusts–providing a significant contribution to the Earth’s early biogeochemistry represents a significant paradigm shift. New research should help establish just how far back in Earth’s record these microbial biocrusts extend and help explore their contributions to the cycling of other elements, like phosphorus.

Desert defenders

Garcia-Pichel’s center is also involved in efforts to restore biocrust communities in desert environments, where urbanization and other factors have seriously degraded them. While these communities show astonishing resilience to the harsh conditions of both desert and polar regions, they are highly sensitive to human interference, including trampling, vehicle traffic and agriculture.

Garcia-Pichel estimates that in the areas around Phoenix, where he works, only 5 percent of the original biocrusts remain. Further, climate change will not only alter the demographics of biocrusts, which vary in their composition according to region, but will render some desert environments too severely arid for their survival. Restoration of these communities is currently a challenging undertaking, part science and part art. The right mix of microbial players must be present for newly seeded communities to survive and flourish.

“When you destroy the crust, you make the soil unstable and very prone to erosion,” Garcia-Pichel says. “Areas that are deforested of crusts are sources of fugitive dust and sand. The natural protection of the desert is not there, and even moderate winds can raise a haboob.

Astronaut  iot  Scott Kelly Views Aurora’s Colorful Veil Over Earth

www.inhandnetworks.com

NASA astronaut Scott Kelly shares his view of an aurora trailing a colorful veil over Earth.

NASA astronaut Scott Kelly (@StationCDRKelly) shared this photograph on social media, taken from the International Space Station on August 15, 2015. Kelly wrote, “#Aurora trailing a colorful veil over Earth this morning. Good morning from @space_station! #YearInSpace”

The dancing lights of the aurora provide spectacular views, but also capture the imagination of scientists who study incoming energy and particles from the sun. Aurora are one ef remote diagnostics  fect of such energetic particles, which can speed out from the sun both in a steady stream called the solar wind and due to giant eruptions known as corona4g lte gatewayl mass ejections or CMEs. After a trip toward Earth that can last two to three days, the solar particles and magnetic fields cause the inhandnetworks  release of particles already trapped near Earth, which in turn trigger reactions in the upper atmosphere in which oxygen and nitrogen molecules release photons of light. The result: the Northern and Southern lights.

Scientists Make 3D Objects Invisibl touchscreen vending  e to Microwave Wavelengths

www.inhandnetworks.com

After years of progress, scientists are now coming closer and closer to making real-world objects disappear from view. Researchers from the University of Texas at Austin have made a three-dimensional object disappear transformer monitoring   from view, from any angle, at microwave wavelengths.

This latest research used plasmonic meta-materials to make an 18-inch cylindrical tube invisible. It was published by Andrea Alu et al in this week’s New Journal of Physics. Objects are visible  Industrial IoT Router/Gateway  because light rays bounce off them, hitting our retinas and allowing our brains to process the information.

Meta-materials redirect light to conceal objects, but the actual cloaking is hard. Plasmonic meta-materials cancel out the light scattering from an object. Once a cylinder is coated with these kinds of materials, they block the light rays, meaning that it becomes invisible.

Previously, meta-materials had been used to create a mirage-like effect using a panel of nanotubes that were electrically stimulated, bending the light rays. It&rsquo intelligent substation  ;s a breakthrough, but before the plethora of applications are considered, researchers need to figure out how they can apply this to optical wavelengths, as their tests were performed with high-frequency wavelengths, like the microwave spectrum.

They’re pursuing their research, but making objects invisible isn’t their priority. The main application of these kinds of materials is to improve biomedical imaging.
