breaking: scientists have confirmed a new dna structure inside human cells

breaking: scientists have confirmed a new dna structure inside human cells it's not just the double helix! peter dockrill 23 apr 2018 for the first time, scientists have identified the existence of a new dna structure never before seen in living cells.the discovery of what's described as a 'twisted knot' of dna in living cells confirms our complex genetic code is crafted with more intricate symmetry than just the double helix structure everybody ociates with dna – and the forms these molecular variants take affect how our biology functions. "when most of us think of dna, we think of the double helix," says antibody the utics researcher daniel christ from the garvan institute of medical research in australia."this new research reminds us that totally different dna structures exist – and could well be important for our cells."the new dna component the team identified is called the intercalated motif (i-motif) structure, which was first discovered by researchers in the 1990s, but up until now had only ever been witnessed in vitro, not in living cells.now, thanks to christ's team, we know the i-motif occurs naturally in human cells, meaning the structure's significance to cell biology – which has previously been called into question, given it had only been demonstrated in the lab – demands new attention from researchers.(zeraati et al., nat chem, 2018)if your only familiarity with dna shapes is the dual helical spirals made famous by watson and crick, the configuration of the intercalated motif could come as a surprise."the i-motif is a four-stranded 'knot' of dna," explains genomicist marcel dinger, who co-led the research."in the knot structure, c [cytosine] letters on the same strand of dna bind to each other – so this is very different from a double helix, whe ... ادامه ...

physicists make id progress in bounding the speed of gravity

physicists make id progress in bounding the speed of gravity november 1, 2017 by lisa zyga artist’s illustration of two merging neutron stars. credit: nsf/ligo/sonoma state university/a. simonnet (phys.org)—recent gravitational wave detections have allowed physicists to confirm with greater and greater precision what einstein predicted over 100 years ago in the theory of general relativity: that gravity does not act instantaneously as newton thought, but instead propagates at the speed of light. "the speed of gravity, like the speed of light, is one of the fundamental constants in the universe," neil cornish, a physicist at montana state university, told phys.org. "until the advent of gravitational wave astronomy, we had no way to directly measure the speed of gravity." over the past few months, physicists have made very id progress in bounding the speed of gravity using gravitational wave observations. initially, the first ligo detections of gravitational waves constrained the speed of gravity to within 50% of the speed of light. in a paper published last week in physical review letters, cornish and his coauthors diego blas at cern and germano nardini at the university of bern have combined the first three gravitational wave events reported by the ligo and virgo collaborations, allowing them to improve the original bounds to within roughly 45% of the speed of light. just two days later (and after the physicists mentioned above wrote their paper), another paper was published in the astrophysical journal letters by the ligo and virgo collaborations, whose authors are affiliated with nearly 200 institutions around the world. by using data from the gravitational waves emitted by a binary neutron star merger detected in august, they were able to constrain the difference ... ادامه ...

why do we dream

the human brain is a mysterious little ball of gray matter. after all these years, researchers are still baffled by many aspects of how and why it operates like it does. scientists have been performing sleep and dream studies for decades now, and we still aren't 100 percent sure about the function of sleep, or exactly how and why we dream. we do know that our dream cycle is typically most abundant and best remembered during the rem stage of sleep. it's also pretty commonly accepted among the scientific community that we all dream, though the frequency in which dreams are remembered varies from person to person. the question of whether dreams actually have a physiological, biological or psychological function has yet to be answered. but that hasn't stopped scientists from researching and speculating. there are several theories as to why we dream. one is that dreams work hand in hand with sleep to help the brain sort through everything it collects during the waking hours. your brain is met with hundreds of thousands, if not millions of inputs each day. some are minor sensory details like the color of a p ... ing car, while others are far more complex, like the big presentation you're putting together for your job. during sleep, the brain works to plow through all of this information to decide what to hang on to and what to forget. some researchers feel like dreams play a role in this process. it's not just a stab in the dark though — there is some research to back up the ideas that dreams are tied to how we form memories. studies indicate that as we're learning new things in our waking hours, dreams increase while we sleep. participants in a dream study who were taking a language course showed more dream activity than those who were not. in light of such studies, the i ... ادامه ...

for the first time, physicists have observed a giant magnetic 'bridge' between galaxies ***

esa/planck for the first time, physicists have observed a giant magnetic 'bridge' between galaxies fiona macdonald 17 may 2017 for the first time, scientists have detected evidence of a magnetic field that's ociated with the vast intergalactic 'bridge' that links our two nearest galactic neighbours. known as the magellanic bridge, the bridge is a huge stream of neutral gas that stretches some 75,000 light-years between our two neighbouring galaxies, the large and small magellanic clouds (lmc and smc). although researchers had predicted it was there, this is the first observation of its magnetic field, and it could help us understand how these vast bridges come to be. "there were hints that this magnetic field might exist, but no one had observed it until now," said lead researcher, jane kaczmarek from the university of sydney. our closest galactic neighbours, the lmc and smc (p og hed below) are 160,000 and 200,000 light-years from earth respectively, and are visible in the southern night sky. eso/j. colosimo researchers have long known about the magellanic bridge that exists between these neighbours, a path with a few known stars inside it. but until now, very little was known about the magnetic field ociated with the bridge. the team has now shown that this newly detected magnetic field is one millionth the strength of earth's own protective magnetic shield - and it could provide some insight into how it formed. two of the leading options are that the magnetic field was generated from within the bridge after the structure formed, or it may have been 'ripped' from the dwarf galaxies thought to have merged and formed the bridge in the first place. if a bridge between the stars sounds a little sci-fi to you, keep in mind that most of space is made up of different magneti ... ادامه ...

study sheds new insights into global warming trends

a new multi-institutional study of the temporary slowdown in the global average surface temperature warming trend observed between 1998 and 2013 concludes the phenomenon represented a redistribution of energy within the earth system, with earth's ocean absorbing the extra heat. the phenomenon was referred to by some as the "global warming hiatus." global average surface temperature, measured by ellites and direct observations, is considered a key indicator of climate change. in a paper published today in earth's future, a journal of the american geophysical union, lead author xiao-hai yan of the university of delaware, newark, along with scientists from nasa's jet propulsion laboratory, pasadena, california, and several other institutions, discuss new understanding of the phenomenon. the paper grew out of a special u.s. climate variability and predictability program (clivar) panel session at the 2015 american geophysical union fall meeting. "the hiatus period gives scientists an opportunity to understand uncertainties in how climate systems are measured, as well as to fill in the gap in what scientists know," said yan. "nasa's examination of ocean observations has provided its own unique contribution to our knowledge of decadal climate trends and global warming," said study co-author veronica nieves of jpl and the university of california, los angeles. "scientists have more confidence now that earth's ocean has continued to warm continuously through time. but the rate of global surface warming can fluctuate due to natural variations in the climate system over periods of a decade or so." where's the missing heat? while yan said it's difficult to reach complete consensus on such a complex topic, a thorough review of the literature and much discussion and debate revealed a ... ادامه ...

99% of the microbes in our own bodies are still a total mystery to science****

99% of the microbes in our own bodies are still a total mystery to science we carry a lot of alien dna. david nield 25 aug 2017 we're seeing incredible scientific discoveries being made every day, but new research indicates there's a pretty huge gap in our knowledge when it comes to our own bodies – it turns out more than 99 percent of the microbes inside us are currently unknown to science. researchers have long known that our bodies play host to a range of tiny lifeforms that make us who we are. in fact, recent studies have shown that every human cell within our bodies is outnumbered by roughly 1.3 microbes. and this latest discovery suggests the overwhelming majority of them are totally alien to us. to figure this out, scientists took a close look at the dna fragments circling in human blood to see what matched up with our current databases of life as we know it. they found that more than 99 percent of the dna they found didn't belong to lifeforms we currently know about. "we found the gamut," says one of the team, bioengineer stephen quake from the bio-x lab at stanford university. "we found things that are related to things people have seen before, we found things that are divergent, and we found things that are completely novel." as well as giving us a new sense of just how crazily diverse our internal microbiomes are, the work could eventually lead to the discovery of new viruses, and better ways to protect ourselves against pandemics. the research actually started out as a study into better ways to predict the success of organ transplants – at the moment doctors use a tissue biopsy (and an uncomfortably large needle) to look for signs of organ rejection, but the stanford scientists wanted to find a less intrusive method. that led to an analysis of blood samp ... ادامه ...

the uk just switched on an ambitious fusion reactor - and it works ***

the uk just switched on an ambitious fusion reactor - and it works first plasma has been achieved. fiona macdonald 1 may 2017the uk's newest fusion reactor, st40, was switched on last week, and has already managed to achieve 'first plasma' - successfully generating a scorching blob of electrically-charged gas (or plasma) within its core. the aim is for the tokamak reactor to heat plasma up to 100 million degrees celsius (180 million degrees fahrenheit) by 2018 - seven times ter than the centre of the sun. that's the 'fusion' threshold, at which hydrogen atoms can begin to fuse into helium, unleashing limitless, clean energy in the process. "today is an important day for fusion energy development in the uk, and the world," said david kingham, ceo of tokamak energy, the company behind st40. "we are unveiling the first world-cl controlled fusion device to have been designed, built and operated by a private venture. the st40 is a machine that will show fusion temperatures - 100 million degrees - are possible in compact, cost-effective reactors. this will allow fusion power to be achieved in years, not decades." nuclear fusion is the process that fuels our sun, and if we can figure out a way to achieve the same thing here on earth, it would allow us to tap into an unlimited supply of clean energy that produces next to no carbon emissions. unlike nuclear fission, which is achieved in today's nuclear reactors, nuclear fusion involves fusing atoms together, not splitting them apart, and it requires little more than salt and water, and primarily produces helium as a waste product. but as promising as nuclear fusion is, it's something scientists have struggled to achieve. the process involves using high-powered magnets to control plasma at ridiculous temperatures for long enough ... ادامه ...

the first ever blueprint for a mind-bendingly m ive quantum computer has been released ***

the first ever blueprint for a mind-bendingly m ive quantum computer has been released "life will change completely." bec crew 2 feb 2017 scientists chasing the dream of quantum computing - technology that would grant us unprecedented processing power - just got their biggest break yet, because the first ever open-source blueprint for a practical quantum computer has been revealed. this blueprint, which outlines how to make a quantum computer the size of a football-pitch, claims to solve previously 'uncrackable' problems using existing technology - meaning the revolutionary technology could be finally within our reach. "[w]e are now publishing the actual nuts-and-bolts construction plan for a large-scale quantum computer," one of the team, winfried hensinger from the ion quantum technology group at sus university in the uk, told the independent. "life will change completely. we will be able to do certain things we could never even dream of before." in case you’re not up to speed with the whole quantum computing saga, the technology was first theorised by nobel prize-winning physicist richard feynman in 1982. it's yet to be built in any kind of practical form, but it's set to revolutionise how we process m ive amounts of data in the future. unlike the computers of today, which are limited to the 1s and 0s of binary code bits, quantum computers are based on qubits. thanks to the 'spooky' quantum effect known as entanglement that occurs in matter at its smallest scale, each qubit can take on the state of 0, 1, or a 'superposition' of the two. so rather than having bits that can only be 1 or 0 at any given moment, qubits can be anything and everything at once. this means they can perform many calculations simultaneously, giving them the potential for unprecedented process ... ادامه ...

johns hopkins researchers want to use big data to chart the brain

the human brain is the most complex machine in existence. every brain is loaded with some 100 billion nerve cells, each connecting to thousands of others, giving around 100 trillion connections. mapping those connections, or synapses, could enable scientists to decipher what causes neurological disease and mental illness. it's an immense, daunting task. the best way to tackle it? use large amounts of data, saysmichael i. miller, a professor in the department of biomedical engineering and university gilman scholar. miller and an interdisciplinary team of johns hopkins researchers are merging their neuroscience, computing, and data science expertise to unravel the brain's mysteries and give other scientists tools to do the same. "we're calling it data-intensive brain science," miller says. in early 2016, the team launched the kavli neuroscience discovery institute at johns hopkins. miller co-directs the institute with richard huganir, director of the department of neuroscience at the school of medicine. they hope to make the kndi a focal point of brain research, pulling together researchers from across johns hopkins institutions. in september, 400 international researchers, ethicists, and government officials gathered in new york for a meeting dubbed the united nations of brain projects. researchers there called for an international brain station, modeled after the international space station, that would create a digital, cloud-based storehouse of neuroscience data accessible to researchers worldwide. at johns hopkins, a trio of engineering researchers—miller;joshua vogelstein, istant professor of biomedical engineering; and randal burns, professor of computer science—is submitting a grant to create a major u.s. brain hub under the domestic brain initiative launched ... ادامه ...

breaking: thunderstorms observed triggering nuclear reactions in the sky

breaking: thunderstorms observed triggering nuclear reactions in the sky they what now? peter dockrill 22 nov 2017 for the first time, scientists have witnessed lightning triggering nuclear reactions in the atmosphere, confirming a hypothesis dating back almost a century. it's long been predicted that high-energy electrons in lightning can produce gamma rays that induce nuclear reactions in thunderclouds, but before now, the phenomenon has never been conclusively observed. "the p onuclear reaction in the atmosphere has been theoretically expected [to be] triggered by such high energy radiation," one of the researchers, astrophysicist teruaki enoto from kyoto university in japan, explained to sciencealert. "several groups have accumulated signatures of this phenomena, such as signals of either neutrons or positrons, which are the products of this reaction." (leonid babich/nature) since the 1980s, scientists have detected these kinds of signals using ground-based observatories, aircraft, and ellites, but before now it was difficult to confirm experimentally that nuclear reactions were yielding the neutrons, positrons, or particles observed. here, enoto and fellow researchers made use of radiation detectors installed at the kashiwazaki-kariwa nuclear power station in niigata, along the coast of the sea of japan. during a thunderstorm in february this year, the team detected "intense radiation" from lightning strikes just off the coast, including a brief gamma ray flash. this was followed by a prolonged gamma ray line at an energy of 0.511 megaelectronvolts (mev) – the energy signature you'd expect to see from positrons and electrons after a nuclear reaction. "this line is a conclusive indication of electron–positron annihilation, and represents unequivocal evidence tha ... ادامه ...

an 87-year-old scientist may have just unlocked the secret to growing rice in saltwater hilary brueck yuan longping is known as the 'father of hybrid rice' in china. getty images / guang niu scientists in china have developed more than 200 new strains of high-yield, saltwater-tolerant rice. the research team hopes the crops will eventually be grown in boggy swamps and coastal areas, and feed as many as 200 million people. recent tests were conducted in diluted salt water that has roughly 10% of the level of salt naturally found in sea water. yuan longping, an 87-year-old chinese scientist, has spent his life working to feed a world hungry for rice. now he's wading into saltier territory. longping is developing a new high-yield strain of rice that can grow in saltwater paddies. the traditional process of cultivating rice requires a field to be flooded with a supply of fresh water. only a fraction of china's total land area can be farmed this way, since much of the soil has salt in it from coastal flooding and tides. in the region of dongying on china's eastern coast, for example, nearly 40% of the land now has salt content above .5%, according to the world bank. (china nonetheless produces more rice than any other country, however.) growing rice in swamps, bogs, and clay-like or salty coastal waters, which comprise about a third of the total arable land in china, has typically been impossible because salt stresses the plants. that makes p osynthesis and respiration a challenge for the stalks, causing them to stop growing and die. an increasing amount of land is expected to face this problem as sea levels rise. if chinese farmers can start planting rice in the vast salty swaths of their country, however, that could dramatically increase the country's food supply. early su ... ادامه ...

****breaking: thunderstorms observed triggering nuclear reactions in the sky

breaking: thunderstorms observed triggering nuclear reactions in the sky they what now? peter dockrill 22 nov 2017 for the first time, scientists have witnessed lightning triggering nuclear reactions in the atmosphere, confirming a hypothesis dating back almost a century. it's long been predicted that high-energy electrons in lightning can produce gamma rays that induce nuclear reactions in thunderclouds, but before now, the phenomenon has never been conclusively observed. "the p onuclear reaction in the atmosphere has been theoretically expected [to be] triggered by such high energy radiation," one of the researchers, astrophysicist teruaki enoto from kyoto university in japan, explained to sciencealert. "several groups have accumulated signatures of this phenomena, such as signals of either neutrons or positrons, which are the products of this reaction." (leonid babich/nature) since the 1980s, scientists have detected these kinds of signals using ground-based observatories, aircraft, and ellites, but before now it was difficult to confirm experimentally that nuclear reactions were yielding the neutrons, positrons, or particles observed. here, enoto and fellow researchers made use of radiation detectors installed at the kashiwazaki-kariwa nuclear power station in niigata, along the coast of the sea of japan. during a thunderstorm in february this year, the team detected "intense radiation" from lightning strikes just off the coast, including a brief gamma ray flash. this was followed by a prolonged gamma ray line at an energy of 0.511 megaelectronvolts (mev) – the energy signature you'd expect to see from positrons and electrons after a nuclear reaction. "this line is a conclusive indication of electron–positron annihilation, and represents unequivocal evidence tha ... ادامه ...

second story

unsung heroes in 1986, three men volunteered to die in order to save hundreds of thousands of people, but most of us have never heard of these unsung heroes. when a nuclear power plant in chernobyl, ukraine began releasing deadly radioactive material, workers didn't know what to do. no one could figure out how to stop the disaster without killing themselves in the process. to make matters worse, the plant was in danger of exploding at any moment. the only way to prevent the explosion was to enter the toxic radioactive water and release a valve. robots were unable to function in the radioactive water, so it would have to be done by a human. three courageous men, knowing full well that this was a death mission, volunteered. alexi ananenko, valeri bezpoalov and boris baronov put on a brave face and their scuba gear. they then dove into the contaminated water and succeeded in releasing the valve. a nuclear meltdown was avoided and hundreds of thousands of people's lives were saved in exchange for three lost. just a few days later, all three men died a difficult death from radiation poisoning. they were buried in lead coffins, which were soldered shut to prevent their bodies from leaking radiation into the soil. they be e known as the "chernobyl suicide squad." even scientists are baffled by rare cases of people who ignore their survival instinct. humans are hard-wired to survive, but heroes ignore the biological voice inside that yells "protect your own life!" while we sometimes hear stories of parents who sacrifice themselves for the life of a child, this too could be seen as the human instinct to survive. our children are part of us and through them our genes survive. in the case of chernobyl, many people might have packed their family up in a car and sped away from the d ... ادامه ...

this physicist says consciousness could be a new state of matter****

this physicist says consciousness could be a new state of matter 'perceptronium'. bec crew 16 sep 2016 consciousness isn't something scientists like to talk about much. you can't see it, you can't touch it, and despite the best efforts of certain researchers, you can't quantify it. and in science, if you can't measure something, you're going to have a tough time explaining it. but consciousness exists, and it's one of the most fundamental aspects of what makes us human. and just like dark matter and dark energy have been used to fill some otherwise gaping holes in the standard model of physics, researchers have also proposed that it's possible to consider consciousness as a new state of matter. to be clear, this is just a hypothesis, and one to be taken with a huge grain of salt, because we're squarely in the realm of the hypothetical here, and there's plenty of room for holes to be poked. but it's part of a quietly bubbling movement within theoretical physics and neuroscience to try and attach certain basic principles to consciousness in order to make it more observable. the hypothesis was first put forward in 2014 by cosmologist and theoretical physicist max tegmark from mit, who proposed that there's a state of matter - just like a solid, liquid, or gas - in which atoms are arranged to process information and give rise to subjectivity, and ultimately, consciousness. the name of this proposed state of matter? perceptronium, of course. as tegmark explains in his paper, published in the journal chaos, solitons & fractals: "generations of physicists and chemists have studied what happens when you group together vast numbers of atoms, finding that their collective behaviour depends on the pattern in which they are arranged: the key difference between a solid, a liquid, an ... ادامه ...
