Dell Talking About 80Core Chip Processor

first_img(PhysOrg.com) — This week Michael Dell (CEO of Dell) gave a slide presentation that included Intel´s recently developed 80-core processor. This isn’t the first time that the 80-core chip was mentioned in a conference. Two years ago CEO of Intel, Paul Otellini, made a promise of delivering an 80-core processor within the next five years. He had also noted that the chips should be able to swap data at a terabyte a second (see video).Video: Intel tests chip design with 80-core processorThis does not mean that future designs of the x86 chip is dead. We will continue to see more and more cores with increased performance and without more power required. The trend, for Intel, is to pack more computing power into smaller machines thereby creating desktop sized supercomputers. Intel’s intention is to continue to bring out many-core processors including its upcoming Larrabee graphics chip and future server processors that may reach 32 cores. Currently, Intel´s Dunnington processor gets the prize for the most cores.© 2008 PhysOrg.com This document is subject to copyright.

Engineering students design a lock picking robot

first_img Citation: Engineering students design a lock picking robot (2011, March 10) retrieved 18 August 2019 from https://phys.org/news/2011-03-students-robot.html The first molecular keypad lock Explore further (PhysOrg.com) — Crimes are usually committed by humans. As it turns out, we are not only making crime happen on our own, but we are designing robots to help us in our extra-legal endeavors. I don’t know what the students at the Olin College of Engineering are up to in their spare time, but they have taken the time to design a robot that picks locks for them. This robot can not only pick a lock, but it can find the combination to any Masterlock lock in under two hours, without resorting to a chisel and hammer. If you have one number things will go much quicker. You won’t get to class in time, but you can do a stealthy pilfering with it, if you have at least half an hour of uninterrupted time to work with. More information: students.olin.edu/2013/jnoglow … ker/The_Project.htmlcenter_img © 2010 PhysOrg.com The robot is surprisingly simple in its design. It all starts with a clamp that is designed to hold the lock in its place. The combination of a thumb-screw, a puller, and a solenoid-controlled grabber then proceed to yank the loop of the lock and give a shot at opening the lock. If this first step is not successful a stepper-motor will engage, turning the knob and dials in various combination’s until it finds the correct one. This hardware, combined with companion software that is known as LockCracker, will keep an eye on what works and what does not. When it finds the correct combination it will actually display the code for future use.For now the device it too big to be used by home invaders, so you will not have to deal with it in the near future. No commercial applications have been given at this time, and the device is not expected to go on sale. This document is subject to copyright.

New theories emerge to disprove OPERA fasterthanlight neutrinos claim

first_imgSchematic view of the Opera Detector The first is by Carlo Contaldi of Imperial College London. He says that it’s likely the OPERA team failed to take gravity into their math equations and its effect on the clocks used to time the experiment. This because the degree of gravity at the two stations involved in the experiment (Gran Sasso National Laboratory in Italy and the CERN facility in Geneva) were different, thus one of the clocks would have been running slightly faster than the other, resulting in faulty timing. If this turns out to be the case, the OPERA team will most certainly be embarrassed to have overlooked such a basic problem with their study.The second is by Andrew Cohen and Sheldon Glashow, who together point out that if the neutrinos in the study were in fact traveling as fast as claimed, they should have been radiating particles as they went, leaving behind a measurable trail; this due to the energy transfer that would occur between particles moving at different speeds. And since the OPERA team didn’t observe any such trail (or at least didn’t report it) it follows that the neutrinos weren’t in fact traveling as fast as were claimed and the resultant speed measurements would have to be attributed to something else.Neither of these papers actually disproves the results found by the OPERA team of course, the first merely suggests there may be a problem with the way the measurements were taken, the second takes more of a “it can’t be true because of…” approach which only highlight the general disbelief in the physics community regarding the very possibility of anything, much less the speed of neutrinos traveling faster than the speed of light, messing with Einstein’s most basic theories. The first can be addressed rather easily by the OPERA team if it so desires, and the second, well, if the neutrinos did in fact travel faster than the speed of light and did so without leaving a trail, a lot of physics theory will have to be rethought. Though that may not necessarily be a bad thing, physics is supposed to be about finding answers to explain the natural world around us after all, even if it means going back to the drawing board now and then. (PhysOrg.com) — It’s been just two weeks since the Oscillation Project with Emulsion-tRacking Apparatus (OPERA) team released its announcement claiming that they have been measuring muon neutrinos moving faster than the speed of light, causing an uproar in the physics community. Since that time, many papers (perhaps as many as 30 to the preprint server arXiv alone) have been published seeking ways to discredit the findings. Thus far though, only two seem credible.

Researchers believe giant pandas can survive on bamboo because of gut bacteria

first_img Explore further 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. (PhysOrg.com) — Because of its cuteness factor, people tend to overlook the fact that giant panda’s are in fact bears, though very few likely forget that most other bears do eat meat. A lot of it. It’s hard to overlook those really big teeth designed to tear and eat flesh. Thus, it seems rather odd that a big bear living in the wild would forgo meat, even though it is still technically a carnivore, and subsist instead almost entirely on bamboo. Yet that’s just what the giant panda does, eating some 12 kilograms of the stuff each day, a feat that would lead to starvation in most other species of bear. So, the question of how they do it has come up, and researchers in China believe they have found the answer. It’s because they have bacteria in their guts that break down some of the cellulose in bamboo for them. Fuwen Wei, and colleagues at the Institute of Zoology at the Chinese Academy of Sciences in Beijing, describe in their paper published in the Proceedings of the National Academy of Sciences, how they found, using DNA analysis, previously unknown types of bacteria in stool samples taken from both wild and captive giant pandas, that they believe allows the animals to get the nutrients they need from simple bamboo.The problem with bamboo is that its cell walls are made of difficult to digest cellulose fibers, which makes it rather useless for most carnivores because most can’t break it down to get at the sugars, fats and proteins that it contains. Other animals (herbivores), such as cows, are able to do it only because they have multiple processing stomachs with all sorts of special microbes to do the job. But carnivores for the most part, simply don’t have the tools necessary to get the job done. One exception, of course, is the giant panda.Wei and his team believe that some of the bacteria they’ve found in the panda stools help the bears break down that cellulose, if only a little bit. A very little bit. In a study conducted at the Washington National zoo several years ago, it was found that pandas only process something like eight percent of the cellulose in the bamboo they eat. Thus, they have to eat not just a lot, but constantly to get enough nutrition from the bamboo to survive.Also helpful for the pandas are strong jaw muscles, sharp teeth and paws that help them to grip stalks. And while all these things contribute to the ability of giant pandas to survive on such a limited diet, they clearly aren’t enough to help them overcome they problem of finding places that have enough bamboo to live on as humans continue to convert land to farm use; thus, their status as an endangered species. Old-growth forests are what giant pandas needcenter_img More information: Evidence of cellulose metabolism by the giant panda gut microbiome, PNAS, Published online before print October 17, 2011, doi: 10.1073/pnas.1017956108AbstractThe giant panda genome codes for all necessary enzymes associated with a carnivorous digestive system but lacks genes for enzymes needed to digest cellulose, the principal component of their bamboo diet. It has been posited that this iconic species must therefore possess microbial symbionts capable of metabolizing cellulose, but these symbionts have remained undetected. Here we examined 5,522 prokaryotic ribosomal RNA gene sequences in wild and captive giant panda fecal samples. We found lower species richness of the panda microbiome than of mammalian microbiomes for herbivores and nonherbivorous carnivores. We detected 13 operational taxonomic units closely related to Clostridium groups I and XIVa, both of which contain taxa known to digest cellulose. Seven of these 13 operational taxonomic units were unique to pandas compared with other mammals. Metagenomic analysis using ∼37-Mbp contig sequences from gut microbes recovered putative genes coding two cellulose-digesting enzymes and one hemicellulose-digesting enzyme, cellulase, β-glucosidase, and xylan 1,4-β-xylosidase, in Clostridium group I. Comparing glycoside hydrolase profiles of pandas with those of herbivores and omnivores, we found a moderate abundance of oligosaccharide-degrading enzymes for pandas (36%), close to that for humans (37%), and the lowest abundance of cellulases and endohemicellulases (2%), which may reflect low digestibility of cellulose and hemicellulose in the panda’s unique bamboo diet. The presence of putative cellulose-digesting microbes, in combination with adaptations related to feeding, physiology, and morphology, show that giant pandas have evolved a number of traits to overcome the anatomical and physiological challenge of digesting a diet high in fibrous matter.

Study of alligator dental regeneration process may lead to tooth regeneration in

first_img More information: Specialized stem cell niche enables repetitive renewal of alligator teeth, PNAS, Published online before print May 13, 2013, doi: 10.1073/pnas.1213202110 AbstractReptiles and fish have robust regenerative powers for tooth renewal. However, extant mammals can either renew their teeth one time (diphyodont dentition) or not at all (monophyodont dentition). Humans replace their milk teeth with permanent teeth and then lose their ability for tooth renewal. Here, we study tooth renewal in a crocodilian model, the American alligator, which has well-organized teeth similar to mammals but can still undergo life-long renewal. Each alligator tooth is a complex family unit composed of the functional tooth, successional tooth, and dental lamina. Using multiple mitotic labeling, we map putative stem cells to the distal enlarged bulge of the dental lamina that contains quiescent odontogenic progenitors that can be activated during physiological exfoliation or artificial extraction. Tooth cycle initiation correlates with β-catenin activation and soluble frizzled-related protein 1 disappearance in the bulge. The dermal niche adjacent to the dermal lamina dynamically expresses neural cell adhesion molecule, tenascin-C, and other molecules. Furthermore, in development, asymmetric β-catenin localization leads to the formation of a heterochronous and complex tooth family unit configuration. Understanding how these signaling molecules interact in tooth development in this model may help us to learn how to stimulate growth of adult teeth in mammals.Press release Citation: Study of alligator dental regeneration process may lead to tooth regeneration in humans (2013, May 14) retrieved 18 August 2019 from https://phys.org/news/2013-05-alligator-dental-regeneration-tooth-humans.html Biological tooth replacement—a step closer Explore further This document is subject to copyright.

Alligator teeth are arranged in tooth family units with 3 members at each position, enabling repetitive replacement. Credit: PNAS, doi: 10.1073/pnas.1213202110center_img (Phys.org) —A team of researchers from the U.S., Taiwan and China analyzing tooth regeneration in alligators reports that a similar process might possibly be instigated in humans through artificial means. In their paper published in the Proceedings of the National Academy of Sciences, the team describes how they uncovered the tooth regeneration process in alligators and why it might apply to human dentistry. © 2013 Phys.org Scientists have long known that tooth regeneration occurs in alligators, but until now, most believed the process followed a schedule—like snakes shedding their skin or birds molting. This new research indicates that the process is actually an on-demand system—when a tooth is lost, a new tooth re-grows in its place. This is an exciting development because alligator tooth structure is very similar to human tooth structure.To find out what actually occurs with alligator tooth replacement, the research team used a variety of techniques (x-rays, tissue analysis, etc.) to study the tooth structure of embryonic, hatchling and three year old alligators. They found that the structure was made up of three parts: a mature tooth, an immature replacement tooth-in-waiting and tissue with stem cells in it. By extracting teeth from a juvenile they were able to watch the tooth replacement process in action. They found that upon loss of a tooth, the tooth-in-waiting began to mature and the tissue with stem cells in it formed a bulge that over time caused the development of a new tooth-in-waiting. The process in alligators is so effective, the researchers found, that all of their 80 teeth are replaced an average of 50 times over their lifetime.The researchers note that because of tooth structure similarity between humans and alligators, it might be possible one day to coax new teeth to grow to replace those that are lost. This is because other studies have shown that humans also have stem cell tissue beneath their teeth. It’s responsible for replacing baby teeth with adult teeth and in rare cases for a condition known as supernumerary teeth—where people grow extra teeth. In humans, the stem cells are believed to shut off after doing their job just once. If a way could be found to turn them back on again, the researchers suggest, it might be possible to cause new teeth to grow when old ones are lost.

Penguin huddling found to be more complicated than thought

first_img © 2015 Phys.org More information: New insights into the huddling dynamics of emperor penguins, Animal Behaviour, Volume 110, December 2015, Pages 91–98. DOI: 10.1016/j.anbehav.2015.09.019AbstractSocial thermoregulation is a cooperative strategy in which animals actively aggregate to benefit from the warmth of conspecifics in response to low ambient temperatures. Emperor penguins, Aptenodytes forsteri, use this behaviour to ensure their survival and reproduction during the Antarctic winter. An emperor penguin colony consists of a dynamic mosaic of compact zones, the so-called huddles, included in a looser network of individuals. To maximize energy savings, birds should adjust their huddling behaviour according to environmental conditions. Here, we examined the dynamics of emperor penguin aggregations, based on photo and video records, in relation to climatic factors. Environmental temperature, wind and solar radiation were the main factors contributing to huddle formation. The analysis of individual movements showed that birds originating from loose aggregations continually joined huddles. Sometimes, a small number of birds induced a movement that propagated to the entire huddle, causing its breakup within 2 min and releasing birds, which then integrated into looser aggregations. Different parts of the colony therefore appeared to continually exchange individuals in response to environmental conditions. A likely explanation is that individuals in need of warmth join huddles, whereas individuals seeking to dissipate heat break huddles apart. The regular growth and decay of huddles operates as pulses through which birds gain, conserve or lose heat. Originally proposed to account for reducing energy expenditure, the concept of social thermoregulation appears to cover a highly dynamic phenomenon that fulfils a genuine regulatory function in emperor penguins. Male emperor penguins huddling to keep themselves and eggs laid by an absent mate warm, has been made famous by the documentary March of the Penguins—they stand, seemingly stoically against the onslaught of bitter cold and frigid wind. Their actions seemed all the more interesting when it was learned that they shift about, moving members from the outside edges towards the center to share the burden of keeping warm. Now it appears that such images may be only part of the story. In this new research effort, the researchers discovered that penguin huddles don’t last very long because the penguins actually get too hot.The team studied approximately 3000 emperor penguins living and huddling in Antarctica’s Pointe Géologie Archipelago colony over the years 2005 and 2006 and then again in 2008. In studying the video recordings they made, they discovered that huddling typically only lasted on average from twelve minutes to a few hours, and the average length of time an individual penguin spent in a huddle was just 50 minutes. They also found that temperatures inside the huddle could get hot, sometimes reaching nearly 100°F under certain conditions. What’s more, they discovered that it typically only took action by a single member to cause the huddle to disperse, and that the individual was generally one on the outside edges.Backing up their theory that it was excessive heat that caused the huddles to disperse, the team found that soon after separating, a haze of warm air was released, and some of the penguins ate some snow, apparently attempting to cool off faster.The team reports that they were surprised to discover that it was generally an outlier that instigated the breakup of huddles, but suggest that may have been because those in the center were trapped by the others around them.

The new age of Voyeurism

first_imgIt is well known that men can be great voyeurs. Voyeurism is a type of high that is common to both men and women; however the former are generally more associated with this kind of activity. Through the ages some men have been peeping toms, ogling at unclad women, through the lens of a binocular or simply chinks in doors or windows. When an undressed woman is unaware that she is being watched, it becomes an ugly infringement on ones privacy, instead of being a simple prank.   Also Read – ‘Playing Jojo was emotionally exhausting’Though voyeurism has been there since the beginning of time, it has finally turned into a very sleazy sport in the new millennium, thanks to a host of gadgets like pinhole cameras or the mobile phones.The mobile phone today has taken the centre stage in this game of voyeurism. Fitted with high resolution cameras they can click pictures with life like colors and picture quality. The new generation of phones in the hand of a voyeur can create havoc in anyone’s life. A hapless girl may be clicked while in the change room or at a sea beach with absolutely no knowledge of such a dangerous prank.  The internet coupled with revolution in communication technology and data transfer mediums like the infamous MMS, have the power to destroy lives at the touch of a button.  Rapid data exchange between users can make a local video recording, accessible to millions.

Buffet successor Indiaborn Ajit Jain among contenders

first_imgWarren Buffett-led Berkshire Hathaway dropped one of the biggest hints about a possible successor to the billionaire investor, describing India-born Ajit Jain and Greg Abel as “world-leading” performers who are “better” business executives than the octogenarian.In his much-anticipated annual letter to shareholders, Buffet praised Jain, who manages the Berkshire Reinsurance Group, for the way he has grown the business over the years. While Buffet stopped short of naming his successor, company Vice Chairman Charles Munger named Jain and Abel, who heads Berkshire’s energy business, while talking about possible successors to Buffett.”But, under this Buffett-soon-leaves assumption, his successors would not be ‘of only moderate ability’. For instance, Ajit Jain and Greg Abel are proven performers who would probably be under-described as ‘world-class’. In some important ways, each is a better business executive than Buffett,” Munger said in his letter to the shareholders.last_img read more

Tips to maintain feather jewellery

first_imgMaintain your feather jewellery by keeping them in a separate storage space, and by going easy on the cleaning part, say experts.Here are some tips to protect feather jewellery. Go with the light moisture wash: Not all kind of feather jewellery can be cleaned, and those that can be washed can’t just be put under the tap. So, if you wish to clean them, hang them on the bathroom wall while you take a shower and let them enjoy the moisture bath from the shower.

But if you want to give a proper cleaning, then do it once in a month because an overload of chemical and water treatment can also harm them. Separate storage space: The feather jewels are extremely soft and delicate and can’t be stored with their counterparts made from heavy metal pieces. They need a space that needs to be both and dust and moisture free as both the elements can bring dullness. Other than that, hanging them is the best option as they face the chances of getting tangled if kept in drawers.Light blow drying to enliven them up: If the feathers get wet, don’t panic.

Household pollutants can cause infertility

first_imgEnvironmental contaminants found in home and diet have the same adverse effects on male fertility both in humans and domestic dogs, finds a new study highlighting the decline in sperm quality in both the species over the past few years. The findings, published in the journal Scientific Reports, showed the chemicals – at concentrations relevant to environmental exposure – have the same damaging effect on sperm of both man and dog. “We know when human sperm motility is poor, DNA fragmentation is increased and that human male infertility is linked to increased levels of DNA damage in sperm,” said co-author Rebecca Sumner, postdoctoral student at the University of Nottingham, Britain. Also Read – Add new books to your shelf”We now believe this is the same in pet dogs because they live in the same domestic environment and are exposed to the same household contaminants,” Sumner said. For the study, the team tested the effects of two man-made chemicals – the common plasticiser DEHP, widely used in the home and the industrial chemical polychlorinated biphenyl 153, which although banned globally, remains widely detectable in the environment, including food. The researchers carried out identical experiments for both species using samples of sperm from donor men and stud dogs, living in the same region. “This new study supports our theory that the domestic dog is indeed a ‘sentinel’ or mirror for human male reproductive decline. Our findings suggest man-made chemicals, widely used in home and working environment, may be responsible for the decline in sperm quality.”last_img read more

This is The End The Conflicting Stories Surrounding Jim Morrisons Passing

He delivered his account on the event of Morrison’s death many years later, in a 2007 book entitled The End: Jim Morrison.Promotional photo of the Doors in late 1966.Reportedly, the idea to pen a book about it was instilled in him by his wife, following years of being chased by journalists to share more on the matter.“The flamboyant singer of The Doors, the beautiful California boy, had become an inert lump crumpled in the toilet of a nightclub,” reads Bernett’s book.Photo of The Doors.Bernett had not seen Morrison taking any drug that evening, but he was provided with heroin in the club by two dealers, according to Reuters.He took it in the men’s toilet where he fell unconscious. The drug dealers, who might have wanted to hush up the details of his death, supposedly carried Morrison from the club to his apartment on 17 Rue Beautreillis.

Photo by Ben Merk (ANEFO) CC BY-SA 3.0If we listen to singer Marianne Faithfull, the finger of blame should be pointed at Jean de Breteuil, a drug dealer and her ex-boyfriend, who supplied Morrison with exceptionally bad heroin at his home.For years she was also the love interest of Mick Jagger from the Rolling Stones. Faithfull became a star during the 1960s after singing “As Tears Go By,” but her popularity declined after dedicating herself to different vices, including heroin.Jim Morrison’s grave in Pere-Lachaise cemetery, Paris.In 1971, Faithful was staying in Paris along with de Breteuil, who personally had told her he needed to check in at Morrison’s place. “I could intuitively feel trouble,” the singer said in 2014, as reported by The Telegraph. “And he went to see Jim Morrison and killed him,” adding, “I mean I’m sure it was an accident.”According to her, the drug was just too strong.While these three varying accounts of Jim Morrison’s death have a touch of reality, other quite far-fetched theories have less. Such as those who propose Morrison’s death was a hoax and he continued to live either in New York City or in Oregon under a newly-adopted identity or those who say the CIA had a part in it in order to get rid of another popular youth leader.The versions provided by Sam Bernett and Marianne Faithfull may hold pieces of truth, nevertheless. And especially Bernett’s story seems to contradict the most accepted account of the tragic death event. Can we really know who is telling the truth? Most of the key players in this drama are also dead now.Read another story from us: Hit the Road Jack!

The Final Humiliation of William the Conquerors Body During his Funeral

first_imgWe have all heard stories about weddings or funerals gone wrong. Maybe we have experienced something ourselves, but odds are you’ve (thankfully) never experienced something as horrifying as what happened at the funeral service for one of the greatest kings in history. William the Conqueror (c.1028-1087), sometimes known as “William the Bastard” (definitely not to his face), was the feudal lord of Normandy who conquered England in 1066, the last time the island nation was subjugated by a foreign foe.William as depicted in the Bayeux Tapestry during the Battle of Hastings, lifting his helm to show that he is still alive.William, the illegitimate son of Duke Robert I and a tanner’s daughter named Herleva, was descended on his father’s side from Rollo, the Norwegian Viking who was given Normandy by the King of France in return for defending France against his pagan brethren.Rollo’s descendants, including William, may have converted to Christianity, but they were just as fierce and lusty as their Viking forefathers.William, in particular, was reputed to have both a fierce temper and a fierce appetite. Both of these traits would leave him essentially without mourners when he died.Château de Falaise in Falaise, Lower Normandy, France. William was born in an earlier building here.Of course, William the Conqueror is hardly the nickname of a timid man or a man without enemies. Though he was “legitimized” by the Church and had become the sole ruler of Normandy by 1047, and had made it the strongest territory in France and essentially a nation unto itself, William’s ambitions came to include becoming King of England as well.His claim to the English throne was a bit tenuous: he was a distant cousin to the English king, Edward the Confessor. Aside from the ties of blood, Edward had spent time in exile in Normandy as a young man, after having been run out of England by the Danish warrior king Canute, who briefly united the kingdoms of Denmark, Norway and England.Edward returned to England upon the death of Canute and ascended the throne with a special place for Normandy in his heart.Image from the Bayeux Tapestry showing William with his half-brothers. William is in the centre, Odo is on the left with empty hands, and Robert is on the right with a sword in his hand.In 1051, the childless Edward invited young William to his court and reportedly promised William the throne when he died. William never forgot that promise – not for a second.However, in the time between 1051 and 1066, Harold Godwinson, the scion of a noble and powerful family and accomplished warrior, had become Edward the Confessor’s brother in law, and was the Earl of Wessex, a powerful position.Harold and his supporters claimed that he was promised the English throne by Edward on his deathbed. The king’s advisers, called the “Witan” or “Witanegemot,” gave Harold the necessary support and he was crowned in January 1066.The signatures of William I and Matilda are the first two large crosses on the Accord of Winchester from 1072.Another claimant to the throne was the legendary Viking warrior Harald Hardrada (or “Hard-ruler”). He claimed the throne of England through Canute the Great.William dismissed both of these claims. The Norwegian claim was based on a line of kings that didn’t exist anymore. Harold’s claim? Well, that was a different story. In 1064, Harold shipwrecked on the Brittany coast of France, a neighboring and rival duchy of Normandy. Threatening Brittany’s lord Conan II with invasion, William demanded Harold be handed over – William knew he was a valuable hostage, and that his family would pay a huge ransom to set him free. That, or William could extract valuable oaths to do so.The remains of Baile Hill, the second motte-and-bailey castle built by William in York.By all accounts (including an illustrated chapter of the famed Bayeux Tapestry), William and Harold got along well – hostage-taking was a regular practice, and noble “guests” were mostly treated with respect and hospitality.Harold even went on campaign with William and reportedly saved the life of two Norman knights stuck in quicksand. In the Tapestry, Harold can be seen pledging to William – that pledge was to honor William’s claim on the English throne. So, when Harold took that throne, William and his Norman knights took him for an oath-breaker, the worst kind of liar there was, and vowed vengeance.Scene from the Bayeux Tapestry whose text indicates William supplying weapons to Harold during Harold’s trip to the continent in 1064.Before William could assemble his fleet and army, Harald Hardrada invaded northern England in September. On September 25th, King Harold defeated the Vikings at Stamford Bridge.It was there that Harold received word that the Normans had landed on England’s southern coast. Racing the length of England, Harold met William at Hastings, about 65 miles south of London. As history records, William was victorious and Harold lay on the field, dead from an arrow taken in the eye.Modern day site of the Battle of Stamford Bridge. Photo by DS Pugh CC BY-SA 2.0Over the course of the rest of his lifetime, William consolidated his hold over England. It was a long and brutal affair, marked by oppression, slaughter and the almost complete suppression of Anglo-Saxon culture.Norman French blended with Anglo-Saxon Old English to begin to form the modern English language. Behind all of this was William, who met any opposition with utter ruthlessness.English coin of William the Conqueror.Along the way, William enjoyed the fruits of his conquest. And the meats. And the ales. He grew immensely fat, and his death was caused when the pommel of his saddle was literally driven into his intestines, puncturing them. The medical men of the time were not able to do anything to help him and he lingered in immense pain for six weeks.He died in Normandy and his heirs left it to medical men (the term is relative) to deal with the body of the feared but unloved king. The corpse had lain in a surgical facility in Rouen for some days before a passing knight had him embalmed out of duty to his lord.William’s grave at Abbaye-aux-Hommes, Caen. Photo by Supercarwaar CC BY-SA 4.0However, decomposition had already set in and the embalming was hardly complete – and there was still an ad-hoc funeral to be held in Caen, the family seat, some seventy miles away.Already in a decrepit state, William’s body suffered further indignities when a fire broke out in the city. Days more went by. Then, a man challenged the local church where his body lay, claiming it had been built on his land.A page from Domesday Book for Warwickshire.By the time this all was settled, weeks had gone by. Though William’s body was wrapped in funeral sheets, it still stank and had bloated up to many times its natural size, which was already large.When the gravediggers went to lower the body, it would not fit in the hole. So they attempted to cram it in. That’s when William I, ruler of Normandy and King of England, exploded. His body rained down on what mourners there were, and a horrible stench filled the air.Read another story from us: The cloth corset worn in 1603 by the funeral effigy of Queen Elizabeth I will be displayed this year at Westminster AbbeyPeople got sick, making a bad situation worse. Others passed out. Most ran away in terror. Finally, what remained of William was dumped in the hole and hastily covered up. That was the last resting place of one of history’s most famous figures.last_img read more

This SelfDriving Car of the Future Doubles as a Living Room

first_img Germany’s Daimler AG wants to reset consumers’ expectations about self-driving cars with its futuristic Mercedes-Benz F 015 concept, unveiled Monday evening at the annual Consumer Electronics Show in Las Vegas.”Anyone who focuses solely on the technology has not yet grasped how autonomous driving will change our society,” said Daimler Chief Executive Officer Dieter Zetsche, one of this year’s keynote speakers at CES. “The car is growing beyond its role as a mere means of transport and will ultimately become a mobile living space.”Until now, automakers such as Daimler and Volkswagen AG’s Audi have largely focused on developing automated systems, including braking and steering, that make cars safer and easier to operate.The F 015 luxury sedan concept, with its spacious cabin and lounge-like seating for four, explores new possibilities for self-driving cars that can double as virtual living rooms on wheels. And in keeping with Mercedes tradition and the concept’s “luxury in motion” theme, the post-modern passenger space is trimmed in walnut veneer, nappa leather, polished aluminum and glass, with soft blue LED lighting.The F 015 can be operated autonomously or manually. When the vehicle is in fully driverless mode, the four motorized lounge chairs can be rotated to allow face-to-face conversations. When required for manual operation, the driver’s chair swivels back to face forward.To facilitate connectivity with the outside world, the F 015 is equipped with six digital display screens throughout the cabin. The screens can be activated via gestures, eye-tracking or touch.Mercedes wrapped all that fancy hardware and software in a lightweight, impact-resistant structure of carbon-fiber, aluminum and high-strength steel. The concept was also designed to accommodate an electric motor and hydrogen fuel cell.The F 015 represents a huge leap forward conceptually and stylistically from the Mercedes-Benz S 500 Intelligent Drive research vehicle that piloted itself on a 100-kilometer journey from Mannheim to Pforzheim in August 2013.The 2013 journey, made in a specially modified S-Class sedan equipped with various automated systems, traced the path driven 125 years earlier by Bertha Benz, wife of company co-founder Karl Benz, in one of the world’s first gasoline-powered automobiles.Mercedes currently equips several of its production vehicles with a variety of semi-automated systems, including parking assist, traffic jam assist and steering assist.The company’s forward vision, embodied in a project titled “City of the Future 2030+”, sees self-driving cars as a springboard for redesigning traffic-dense urban spaces with unique “safety” zones accessible only by autonomous vehicles.(Reporting by Paul Lienert in Las Vegas; Editing by Alan Crosby) Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goals This story originally appeared on Reuters January 6, 2015 Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right. 3 min read Register Now »last_img read more

5 Hot IoT Trends to Keep Your Eye On

first_img The Internet of Things (IoT), or the ability to connect everyday objects to the internet, has increased in popularity and widespread use over the last several years. According to IoT analytics, the global IoT market will grow to $1,567B by 2025. Various industries have already implemented the technology, which offers benefits for individuals and organizations alike. Its uses are diverse, with the potential to impact verticals ranging from retail to architecture to the ways we interact with our own homes. While IoT has been trending for some time, it is going to take on a more significant role in the next year, impacting our lives on a previously unprecedented scale. Here are the five hottest IoT trends to keep your eye on right now.1. IoT devices will be more secure.Security is one of the primary concerns that comes with IoT use. Because the market is still relatively unregulated, device hacking and data theft have been issues that the industry is actively trying to solve. The stakes are high when it comes to IoT devices (take self-driving cars and home security, for example), and security solutions are of primary importance. One of the most promising solutions for IoT security is blockchain technology. Because of its strong protections against data tampering and its ability to rapidly shut down or lock tampered devices, it may prove promising for the IoT market. The Hyundai Digital Asset Currency (HDAC), for example, aims to protect user privacy and remove hacking threats by connecting all IoT devices within their trust-based and secure blockchain token system.In addition to blockchain, mobile-device management solutions and two-factor authorization could provide additional safety measures. Related: IoT Disruption Has Begun. And Retail Is Just the Start.2. More data will be sold.“Infonomics,” or the practice of selling data, is continuously growing more immense. The potential value of data collected by IoT devices is huge, with companies gaining the opportunity to interact with information that was previously unavailable. The “data-as-a-service” (DaaS) offers channels through which companies buy and sell data, and this market alone is growing; however, this isn’t an ideal way to sell IoT-based data. As a result, innovators are creating marketplaces explicitly designed with IoT devices in mind. 3. Our cities will get smarter.Forward-thinking cities are adopting IoT technologies to make their communities more accessible, efficient and safe. People are migrating to cities for better employment prospects and more diverse lifestyles, and IoT technologies will better allow cities to adapt to this growth. IoT devices use city-wide sensors and meters to collect data and use the acquired information to build better infrastructure and offer necessary public services. The European Union has largely been leading the way for the implementation of smart cities, with an allocation of 365 million Euros specifically for this purpose. Copenhagen, for example, uses sensors to monitor bike traffic and gather data for improved routes to better serve its heavily bike-dependent city. U.S. cities fall behind those in Europe when it comes to the implementation of smart technology; however, cities across the country will likely use more IoT-based practices over the next few years. 4. It will play a more prominent role within our homes.Just as IoT is leading to the creation of “smart cities,” IoT devices are also creating “smart homes.” It’s now easy to set-up most appliances and control them remotely through the internet. Google Nest, for example, automatically controls heat and hot water, and the company has even produced smart smoke detectors and security cameras. Big brands are also making investments in new IoT companies as they continue to innovate in their respective industries. AI-based smart kitchen assistant Chefling recently raised $2.5 M in series funding, and Bosch subsidiary BSH Hausgeräte GmbH brought one-third of the shares of the company. As a result, Chefling will be integrated into the Home Connect system and help consumers to automate cooking and receive access to personalized recipes based on what’s available in the kitchen at the time, dietary restrictions and other preferences.Related: 25 Innovative IoT Companies and Products5. Retail will further adopt IoT to  improve customer experience.Retail-based businesses across the country are going to use IoT, both for online purchases and with brick-and-mortar shopping. IoT devices will allow retailers to determine how long consumers spend interacting with products and can collect data about in-store foot traffic. All of this information lets businesses decide which products are best suited for their customers and create experiences suited specifically for their audience. Speaking of connected devices, my comedy book about prison hits the shelves next month.
