One of the possible outcomes of the measurement corresponds to the final condition that we would like to impose. Whenever that outcome occurs, then everything that has happened in the experiment up to that point is exactly the same as if the photon had gone backward in time and tried to kill its former self. So when we ‘post-select’ that outcome, the experiment is equivalent to a real CTC.”To demonstrate, the scientists stored two qubits in a single photon, one of which represents the forward-traveling qubit, and one of which represents the backward-traveling qubit. The backward-traveling qubit can teleport through a quantum channel (CTC) only if the CTC ends by projecting the two entangled qubits into the same state.After the qubits are entangled, their states are measured by two probe qubits. Next, a “quantum gun” is fired at the forward-traveling qubit, which, depending on the gun’s angle, may or may not rotate the qubit’s polarization. The qubits’ states are measured again to find out if the gun has flipped the forward-traveling qubit’s polarization or not. If both qubits are in the same state (00 or 11), then the gun has not flipped the polarization and the photon “survives.” If the qubits’ states are not equal (01 or 10), then the photon has “killed” its past self. The experiment’s results showed that the qubits’ states were almost always equal, showing that a qubit cannot kill its former self.The scientists noted that their experiment cannot test whether an actual CTC obeys their new theory, since it is currently unknown whether CTCs exist at all. In the future, they plan to perform more tests to better understand time travel paradoxes.“We want to perform the so-called `unproved theorem paradox’ experiment, in which the time traveler sees an elegant proof of a theorem in a book,” Lloyd said. “She goes back in time and shows the proof to a mathematician, who includes the proof in the book that he is writing. Of course, the book is the same book from which the time traveler took the proof in the first place. Where did the proof come from? Our theory has a specific prediction/retrodiction for this paradox, which we wish to test experimentally.” Explore further Copyright 2010 PhysOrg.com. All rights reserved.

Image caption: Seth Lloyd, et al. ©2011 American Physical Society. In a new study, a team of researchers has proposed a new theory of CTCs that can resolve the grandfather paradox, and they also perform an experiment showing how such a scheme works. The researchers, led by Seth Lloyd from MIT, along with scientists from the Scuola Normale Superiore in Pisa, Italy; the University of Pavia in Pavia, Italy; the Tokyo Institute of Technology; and the University of Toronto, have published their study in a recent issue of Physical Review Letters. The concepts in the study are similar to an earlier study by some of the same authors that was posted at arXiv.org last year.“Einstein’s theory of general relativity supports closed timelike curves,” Lloyd told PhysOrg.com. “For decades researchers have argued over how to treat such objects quantum mechanically. We believe that our theory is the correct theory of such objects. Moreover, our theory shows how time travel might be accomplished even in the absence of general relativistic closed timelike curves.”In the new theory, CTCs are required to behave like ideal quantum channels of the sort involved in teleportation. In this theory, self-consistent CTCs (those that don’t result in paradoxes) are postselected, and are called “P-CTCs.” As the scientists explain, this theory differs from the widely accepted quantum theory of CTCs proposed by physicist David Deutsch, in which a time traveler maintains self-consistency by traveling back into a different past than the one she remembers. In the P-CTC formulation, time travelers must travel to the past they remember.Although postselecting CTCs may seem complicated, it can actually be investigated experimentally in laboratory simulations. By sending a “living” qubit (i.e., a bit in the state 1) a few billionths of a second back in time to try to “kill” its former self (i.e., flip to the state 0), the scientists show that only photons that don’t kill themselves can make the journey. “P-CTCs work by projecting out part of the quantum state,” Lloyd said. “Another way of thinking about closed timelike curves is the following. In normal physics (i.e., without closed timelike curves), one specifies the state of a system in the past, and the laws of physics then tell how that state evolves in the future. In the presence of CTCs, this prescription breaks down: the state in the past plus the laws of physics no longer suffice to specify the state in the future. In addition, one has to supply final conditions as well as initial conditions. In our case, these final conditions specify the state when it enters the closed timelike curve in the future. These final conditions are what project out part of the quantum state as described above. (PhysOrg.com) — Among the many intriguing concepts in Einstein’s relativity theories is the idea of closed timelike curves (CTCs), which are paths in spacetime that return to their starting points. As such, CTCs offer the possibility of traveling back in time. But, as many science fiction films have addressed, time travel is full of potential paradoxes. Perhaps the most notable of these is the grandfather paradox, in which a time traveler goes back in time and kills her grandfather, preventing her own birth. This document is subject to copyright.

Researchers find epigenetic factor in monogamy for voles

first_img Citation: Researchers find epigenetic factor in monogamy for voles (2013, June 3) retrieved 18 August 2019 from https://phys.org/news/2013-06-epigenetic-factor-monogamy-voles.html Steady relationships reduce amphetamine’s rewarding effects (Phys.org) —A team of researchers at Florida State University has found an epigenetic factor involved in voles’ lifelong pair bonding. In their paper published in the journal Nature Neuroscience, the researchers describe how they found the act of mating—along with time spent alone—led to permanent brain changes in the voles involved in the study. This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Voles are famously monogamous, leading some to note that switching the letters around in their name spells the word “love.” But the factors that lead to such pair bonding have remained somewhat of a mystery. Researchers have known for some time that vole pairs have higher levels of neurotransmitters—vasopressin and oxytocin—in their brains, but until now, haven’t been able to explain why. In this new study, the researchers have found that the act of mating, combined with time spent along together, causes permanent changes to chromosomes that lead to changes in genes that are responsible for creating monogamous behavior.Suspecting an epigenetic factor (chemical changes to chromosomes that impact how genes are transcribed) was at play, the researchers tested captive voles in a variety of circumstances for neurotransmitter levels. Some voles were housed together for six hours but weren’t allowed to mate—others were housed together long enough to encourage mating (typically a full day). Some of the voles that were not allowed to mate also had the histone trichostatin A (TSA) injected into a part of their brain—the nucleus accumbens—it’s known to play a part in their monogamous behavior. Other voles without injections were allowed to behave naturally.In studying the results of their experiments, the researchers found that voles housed for just six hours with prospective mates that also received TAS injections, became bonded mates regardless of whether they actually mated or not—and genes for the neurotransmitter receptors had been transcribed, which meant the changes were permanent. Subsequent testing of such pairs showed the bonded animals exhibited the same raised levels of neurotransmitters as those who mated naturally in the wild. They also found that voles being housed together was just as important as the chemical injection—those housed for shorter times, despite the dose of TSA, did not bond. This, they say, suggests that the bonding that occurs has more than one component. Spending time together before mating, they note, causes some sort of mental imprinting that when combined with raised neurotransmitter levels, causes the voles to want to mate with just their partner for the rest of their lives. Explore furthercenter_img More information: Histone deacetylase inhibitors facilitate partner preference formation in female prairie voles, Nature Neuroscience (2013) doi:10.1038/nn.3420AbstractIn the socially monogamous prairie vole (Microtus ochrogaster), mating induces enduring pair-bonds that are initiated by partner preference formation and regulated by a variety of neurotransmitters, including oxytocin, vasopressin and dopamine. We examined potential epigenetic mechanisms mediating pair-bond regulation and found that the histone deacetylase inhibitors sodium butyrate and trichostatin A (TSA) facilitated partner preference formation in female prairie voles in the absence of mating. This was associated with a specific upregulation of oxytocin receptor (OTR, oxtr) and vasopressin V1a receptor (V1aR, avpr1a) in the nucleus accumbens (NAcc), through an increase in histone acetylation at their respective promoters. Furthermore, TSA-facilitated partner preference was prevented by OTR or V1aR blockade in the NAcc. Notably, mating-induced partner preference triggered the same epigenetic regulation of oxtr and avpr1a gene promoters as TSA. These observations indicate that TSA and mating facilitate partner preference through epigenetic events, providing, to the best of our knowledge, the first direct evidence for epigenetic regulation of pair-bonding. Male and female prairie voles develop strong partner preference after mating and stay together for life. After developing the strong bond, they become aggressive and exhibit mate-guarding towards intruders of opposite sex. Finally, after they have pups, both mom and dad participate equally in taking care of them. Credit: Dr. Zuoxin Wang © 2013 Phys.org Journal information: Nature Neurosciencelast_img read more

Researchers suggest Vikings used crystals with sun compass to steer at night

first_img Since the discovery of the sun compass fragment, researchers have theorized that Viking sailors used them to plot their course—at least when the sun was shining. They didn’t have magnetic compasses, however, which suggest they must have had some other means for steering in the evening or the later hours. In this latest effort, the researchers describe a scenario where the Vikings might have used a type of crystal that they called a sunstone to help them use light from the sun below the horizon as a guide.The sun compass fragment, prior research has suggested, operated in similar fashion to a sundial, using the position of the sun to determine direction, instead of time. Some have suggested the Vikings also used a dome shaped object with slits in it, placed on top of the compass to help narrow the light during the time when the sun moved low towards the horizon. The researchers in Hungary are now suggesting that they also added calcite stone crystals for use after the sun went below the horizon. They’ve conducted tests which show that the crystals can be used to note where the sun is after it’s passed below the horizon, because they direct ultraviolet light into patterns inside the stone, which can be seen by the human eye. If such stones were used, the Vikings could have used them all night long in the northern latitudes as it never goes completely dark.The researchers back up their theory by noting that Viking literature is rife with references to sun stones, though none have ever been “officially” discovered. One crystal has been found amongst navigational tools on a sixteenth century sunken ship, but no one has been able to prove it was actually used as a navigational aid.

Twilight board as a new interpretation of the Uunartoq artefact fragment, Proceedings of the Royal Society A, Published 26 March 2014 DOI: 10.1098/rspa.2013.0787AbstractVikings routinely crossed the North Atlantic without a magnetic compass and left their mark on lands as far away as Greenland, Newfoundland and Baffin Island. Based on an eleventh-century dial fragment artefact, found at Uunartoq in Greenland, it is widely accepted that they sailed along chosen latitudes using primitive Sun compasses. Such instruments were tested on sea and proved to be efficient hand-held navigation tools, but the dimensions and incisions of the Uunartoq find are far from optimal in this role. On the basis of the sagas mentioning sunstones, incompatible hypotheses were formed for Viking solar navigation procedures and primitive skylight polarimetry with dichroic or birefringent crystals. We describe here a previously unconceived method of navigation based on the Uunartoq artefact functioning as a ‘twilight board’, which is a combination of a horizon board and a Sun compass optimized for use when the Sun is close to the horizon. We deduced an appropriate solar navigation procedure using a twilight board, a shadow-stick and birefringent crystals, which bring together earlier suggested methods in harmony and provide a true skylight compass function. This could have allowed Vikings to navigate around the clock, to use the artefact dial as a Sun compass during long parts of the day and to use skylight polarization patterns in the twilight period. In field tests, we found that true north could be appointed with such a medieval skylight compass with an error of about ±4° when the artificially occluded Sun had elevation angles between +10° and −8° relative to the horizon. Our interpretation allows us to assign exact dates to the gnomonic lines on the artefact and outlines the schedule of the merchant ships that sustained the Viking colony in Greenland a millennium ago. Researchers: We may have found a fabled sunstone (Update) (Phys.org) —A team of researchers working in Hungary has proposed that a sun compass artifact found in a convent in 1948 might have been used in conjunction with crystals to allow Vikings to guide their boats even at night. In their paper published in Proceedings of the Royal Society A: Mathematical, Physical & Engineering Sciences, the team describes theories they’ve developed that might explain how Viking sailors were able to so accurately sail to places such as Greenland.last_img read more

Power dept to install smart meters in Siliguri

first_imgKolkata: The state Power department will start installation of smart meters for the first time, as part of a pilot project in Siliguri. The installation is expected to kick off from the month of July-August.A senior official of the state Power department said that the smart meters will be installed at 5,000 households, which will be connected to a single feeder. “We will monitor the use for a period of at least a year and then a decision will be taken on whether we will go for more such meters,” the official said. Also Read – Heavy rain hits traffic, flightsThe process of integration of software and hardware and other necessary infrastructure for adopting the new technology is going on in full swing. The smart meter is already in use at some places in the industrial and agriculture sectors.It may be mentioned that the Central government in 2011 had selected five to six states across the country, including Bengal, for a scheme on smart meters, whereby it had allocated 50 percent funds for the project. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedThe tendering process took a long time because of some financial problems associated with the executing company and of course because of the advanced technology involved in the project.Smart meters are very much effective in curbing hooking and pilferage, which has always been a matter of concern for West Bengal State Electricity Distribution Company Limited (WBSEDCL). It also contributes in bringing down pollution and ensure uninterrupted supply of good quality power. However, installation of smart meters entail a huge expense and the Siliguri pilot project involves an investment of more than Rs 5 crore.Elaborating on the advantages of smart meters both from the consumer and the department’s point of view, the official said that consumers will be able to automatically control electrical appliances from a remote location, while the utility company will be able to monitor electricity usage round the clock from its centralised server.”It also allows a consumer to reduce costs by increasing energy consumption during off-peak cheaper tariff periods,” the official said.It may be mentioned that the state Power department has already checked power theft for 8,000 big industries across the state, by implementing the technology of taking reading directly on a daily basis.The state Power department is holding talks with a number of foreign companies from countries like Japan, China, Korea, Europe and South Africa on using devices that cause less pollution in the Power sector.last_img read more

One arrested for duping people under pretext of providing land

first_imgKolkata: The Bidhannagar South Police station arrested a person on Wednesday night on charges of duping a woman under the pretext of providing her with a land at Baota mouza under Kolkata Leather Complex police station area.The victim Urmila Das, a resident of FC Block in Salt Lake Sector III had lodged a complaint with the police on April 8, against one Francis Chatterjee alleging that the latter had taken a huge amount of money from her by giving false assurance that he would hand over a plot of land under Baota mouza in Kolkata Leather Complex within a short period of time by making sale deed of the property. However, when he ultimately didn’t handover the said land even after a reasonable amount of time, she realised that she has been cheated and lodged the compliant.During the course of investigation, police have found out that the person has cheated others in the same manner and amassed a huge amount of money by illegal means. “The amount of forgery will be to the tune of a few lakhs,” an officer of Bidhannagar North Police station said.

Male attractiveness not linked to womens hormone levels

first_imgDo you think women tend to prefer a particular type of man when they are fertile? If you think so, nothing could be further from the truth as a new study says that women’s perceptions of male attractiveness do not vary according to their hormone levels.These findings, published in the journal Psychological Science, run counter to the common assumption that sexual selection pressures lead women to prefer more masculine mates, who supposedly have greater genetic “fitness,” when they are most fertile and most likely to conceive. Also Read – Add new books to your shelf”We found no evidence that changes in hormone levels influence the type of men women find attractive,” said lead researcher Benedict Jones of the University of Glasgow in Britain.”This study is noteworthy for its scale and scope – previous studies typically examined small samples of women using limited measures,” Jones explained. “With much larger sample sizes and direct measures of hormonal status, we were not able to replicate effects of hormones on women’s preferences for masculine faces,” Jones said. To address the limitations of previous studies, the researchers recruited nearly 600 heterosexual women to participate in a series of weekly test sessions. In each session, the participants reported whether they were currently in a romantic relationship and whether they were currently using hormonal contraceptives. In each face-preference task, the participants saw 10 pairs of male faces and selected the face in each pair that they found more attractive, rating how strong their preference was. The two faces in each pair were digitally altered versions of the same photo – one face was altered to have somewhat feminised features and the other was altered to have somewhat masculinised features. As expected, women generally rated the masculinised faces as more attractive than the feminised faces. Preference for the more masculinised faces was also slightly stronger when women judged attractiveness in the context of a short-term relationship as opposed to a long-term relationship.However, there was no evidence that women’s preferences varied according to levels of fertility-related hormones.last_img read more

This is how smell forms distinct memories

first_imgDo you know why you instantly recall the smell of apple pie prepared way back by your grandmother as you walk into her kitchen? There is a scientific reason behind it.Researchers have now discovered the mechanism behind how smells that one has experienced in the past have contributed in the formation of memories – suggesting a novel perspective on the way senses are represented in memory.The findings may explain why the loss of the ability to smell has been recognised as an early symptom of Alzheimer’s disease and can offer opportunities for improved smell tests in Alzheimer’s disease diagnosis. Also Read – Add new books to your shelf”Our findings demonstrate for the first time how smells we’ve encountered in our lives are recreated in memory,” said lead author Afif Aqrabawi from the University of Toronto.”In other words, we have discovered how you are able to remember the smell of your grandma’s apple pie when walking into her kitchen,” Aqrabawi added.For the study, published in the journal Nature Communications, the team examined the strong connection between memory and olfaction – the process of smelling and recognising odours in the mice. Also Read – Over 2 hours screen time daily will make your kids impulsiveThey found that information about space and time integrate within a region of the brain important for the sense of smell known as the anterior olfactory nucleus (AON).While examining the function of AON, the team uncovered a previously unknown neural pathway between it and the hippocampus – a structure critical for memory and contextual representation, and highly implicated in Alzheimer’s disease.Mice whose hippocampus–AON connection was left intact, refrained from returning to familiar locations to sniff odours that were no longer novel whereas those with a disconnected pathway returned to sniff previously smelled odours for longer periods of time. “They prefer to spend more time smelling a new odour than one that’s familiar to them. When they lose this preference, it’s implied they no longer remember the smell even though they have sniffed it before, so they continue to smell something as if for the first time,” said Aqrabawi.”…we now understand which circuits in the brain govern the episodic memory for smell. The circuit can now be used as a model to study fundamental aspects of human episodic memory and the odour memory deficits seen in neurodegenerative conditions,” he added.last_img read more

Dollar Princesses – The Young American Ladies Sold to the British Aristocracy

first_imgIn the late 19th and early 20th centuries, hundreds of American women flocked to the United Kingdom in search of eligible, aristocratic bachelors. These were the so-called “Dollar Princesses”, wealthy American heiresses hoping to infiltrate the upper echelons of the British imperial elite. In this period, the United States was a relatively young country without an aristocracy. Rich Americans seeking to elevate their status, therefore, had to look across the pond to their British neighbors in order to secure links to noble families.For British aristocratic families, on the other hand, this foreign interest in their titles presented a significant opportunity. According to Smithsonian Magazine, several established families and estates were struggling in the late 19th century, and many British nobles were actually strapped for cash.The Gilded AgeAs the glory of the British Empire reached its pinnacle, some members of the upper strata of the British elite were struggling to keep up appearances.Marrying a wealthy foreigner was the ideal way to boost the family income and inject a blast of American glamor into the staid and conservative British aristocracy. The Dollar Princesses were often young, beautiful, and wealthy enough to sustain a lavish lifestyle.Moreover, by marrying British nobles they significantly raised their rank and influence and emerged as important political and social actors in the late 19th and early 20th centuries.Portrait of Lady Randolph Churchill, c. 1880According to the Smithsonian Magazine, the first of these affluent American émigrés was Jennie Jerome, the daughter of a fantastically rich American financier and speculator.Born in Brooklyn, and a notable beauty, Jennie was introduced to the young Lord Randolph Churchill by the then-Prince of Wales, later to become Edward VII.Within days they were engaged, although the official announcement was not made for several months, as their parents haggled over the marriage settlement.Lord Randolph Churchill and Lady Randolph Churchill in Paris (1874) by Georges PenabertAs part of this agreement, Jennie brought with her £50,000, and a personal annual allowance of £1000. This was an enormous sum that transformed the fortunes of the young Lord Randolph, who until this point had been reliant on a small stipend from his father, the 7th Duke of Marlborough.This marriage was significant for a number of reasons, not least because Jennie and Randolph’s first child was named Winston, and he would grow up to be Britain’s most famous and arguably most important political leader. However, according to Smithsonian Magazine, the union did not escape public scrutiny and was colored by scandal.Lady Randolph Churchill with her two sons, John and Winston, 1889First, Winston was actually born only seven months after the marriage had taken place, leading to speculation that he had been conceived out of wedlock.Second, both Jennie and Randolph engaged in several scandalous extra-marital affairs and Jennie was even reported to have had a dalliance with the Prince of Wales.Regardless of the gossip, her society connections gave her significant influence in political circles, and she was instrumental in furthering the careers of both her husband and her son.Jennie Spencer-Churchill photographed in 1889Jennie’s successful integration into British high society encouraged other American families to search for eligible bachelors on the other side of the Atlantic.However, not all of these marriages were successful. Consuelo Vanderbilt, from one of the wealthiest families in the United States, was bitterly upset when she was forced, against her will, to marry the Duke of Marlborough.Consuelo VanderbiltShe later recounted that she wept on the day of her wedding and she was very unhappy in her marriage. Both partners had a string of affairs and eventually separated after 10 years.It is estimated that around 350 wealthy American women married into the British aristocracy between the late 19th century and the outbreak of the Second World War.Many of these Dollar Princesses were effectively “sold” by their families and forced into a loveless marriage and a life that was not their choice.Consuelo Vanderbilt with her fatherNevertheless, they often exploited their new status to become influential political and social actors in their own right.Read another story from us: The Founding Mother – George Washington’s Mom was Quite the CharacterIcons of the so-called Gilded Age, these women brought an estimated $25 billion into the British economy, shoring up many ancient aristocratic families and shaking up British elite culture in the process.last_img read more

Nick Wright Deflategate Scissors accidents The Patriots are headed to the Super

first_img Advertisement So, Brady won’t suit up for the Patriots in the regular season until Week 4. And now, because of Scissorsgate, it remains to be seen if he takes a snap in the preseason.Today in The Herd, Nick Wright sat in for Colin, and confidently proclaimed that it doesn’t matter, the Patriots are headed to the Super Bowl.“Tom Brady’s sliced finger be damned. The four game suspension be damned. There is not a time since Tom Brady has been there that they head into a season with a clearer path to the Super Bowl. Period. Point blank.”Nick pointed supported his proclamation by pointing out that the NFL, much like the NBA, is top heavy, with the NFC comparing to the Western Conference. While the Panthers, Cardinals, Packers, Seahawks will need to endure a death march to make it to the Super Bowl, the Patriots should be at full strength against the flawed elite of the AFC.The Broncos don’t have a quarterback, the Bengals have Andy Dalton and no Hue Jackson, the Steelers defense is a sieve, and the Chiefs are 3 yards and a cloud of playoff elimination.The NFL Playoffs are all about momentum. Even if Brady misses the first four games, by the time the playoffs roll around the Patriots will be on a roll he will have a death stare like Hannibal Lecter at human flesh convention.The Patriots have never had a clearer path to the Super Bowl. #TheHerdhttps://t.co/MFW2A3Co7w— Herd w/Colin Cowherd (@TheHerd) August 19, 2016 Bad things do happen to beautiful people. Everybody, including remote alien species that casually eavesdrop on human civilization, already know about Tom Brady’s four game Deflategate suspension to start the NFL regular season.Then last night, Brady was scratched from a scheduled preseason start against the Chicago Bears after bizarrely slicing his thumb on a pair of scissors. What the hell is going on here? This isn’t Tom Brady’s life, it sounds like Brandon Weeden’s.BREAKING: Brady misses start after slicing thumb with scissors prior to Thursday’s preseason game https://t.co/38inBngO8y— Tom E.

NFL OT rule outrage because its the Pats

The argument looks even more ridiculous because the Saints had the ball first in their overtime game against the Rams, and still lost.last_img read more
