These quantum mechanics equations, originally developed to describe the wave-like behavior of electrons in atoms, have since been used for a variety of wave systems. The scientists found that two-wave cases behave much differently than single waves, which exhibit standard instabilities and dissolve into a wide spectrum of waves.”We have presented a theoretical study of the modulational instabilities of a pair of nonlinearly interacting two-dimensional waves in deep water, and have shown that the full dynamics of these interacting waves gives rise to localized large-amplitude wave packets,” wrote the scientists in a recent issue of Physical Review Letters. “[T]wo water waves can, when nonlinear interactions are taken into account, give rise to novel behavior such as the formation of large-amplitude coherent wave packets with amplitudes more than 3 times the ones of the initial waves.”Using the Schrodinger equations, the scientists studied the impact of different wave speeds and different angles at which two waves intersect. The team found that for a certain, relatively small angle, a new instability arises with a “maximum growth rate that is more than twice as large as the ones for the single wave cases,” they report. Two waves meeting at such an angle would escape normal stabilizing effects and exhibit constructive interference that would result in a freak wave. Strong currents can help further by “focusing” waves, continually building them up to giant sizes.”This particular piece of research describes a possible mechanism behind rogue wave formation,” said Marklund. “In order to statistically predict their location, one will need further observations and analysis of such data using various methods, in particular statistical analysis and computer simulations.”Citation: Shukla, P.K., Kourakis, I., Eliasson, B., Marklund, M. and Stenflo, L. “Instability and Evolution of Nonlinearly Interacting Water Waves.” Physical Review Letters. 97, 094501 (2006).By Lisa Zyga, Copyright 2006 PhysOrg.com On a stormy April day in 1995, the RMS Queen Elizabeth 2 was sailing in the North Atlantic when the ocean liner dipped into a “hole in the sea.” Out of the darkness, a towering 95-foot wave threatened to crash down upon the vessel, which the 70,000-ton ship attempted to surf in order to avoid being pummeled to the bottom of the ocean. Explore further A freak wave approached this oil freighter, the Esso Languedoc, near Durban, South Africa in 1980. The masts are about 82 feet above sea level, but the wave, which broke over the deck, caused only minor damage. Photo credit: Philippe Lijour. Fortunately, the ship and passengers survived, but the instance occurred just months after the first scientific recording confirmed the validity of old sailors’ tales once considered skeptical: the existence–and prevalence–of freakishly giant waves, also known as rogue waves.Before the first laser measurement of a freak wave in January 1995, oceanographers and mathematicians predicted that such monster waves should only occur about once every 10,000 years. But as the occurrence inspired satellite measurements, scientists observed many more freak waves than theory predicted. In fact, observations imply that a handful of these waves is occurring at every moment somewhere on the ocean. Although it’s controversial just how many ships and lives have been lost in modern times due to these fairly common giant waves, most ships today are only built to withstand waves up to 50 feet tall–while freak waves have been calculated to reach heights of up to 198 feet. Technically, a freak wave is defined as a wave that is twice the “significant wave height,” which is the mean of the largest third of waves in an area.Intrigued and terrified by freak waves and their potential for swallowing giant ships whole (from oil rigs to cruise ships), scientists are trying to formulate a theory or theories to describe the evolution of these mythical realities. Recently, scientists from Sweden and Germany, Padma Shukla et al., have presented the first analysis and simulation of its kind for the instability of nonlinear waves interacting in deep water. In the past, nonlinear theories have seemed capable of explaining the greater prevalence of rogue waves than previous theories which were linear.”The basic reason for the occurrence of freak waves seems to be what is known as nonlinear wave interactions–by a certain mechanism there is an energy exchange between the waves resulting in a large growth in wave amplitude, much larger than what would be possible through ordinary linear superposition of waves,” coauthor Mattias Marklund told PhysOrg.com. Nearly all waves originate as ripples on the water’s surface blown by the wind. (The exception is tsunamis, which are caused by seismic tremors on the ocean floor and only become dangerous when they reach the shore.) Most waves, however, die down due to viscosity in the water, unless heavy winds cause the swells to increase. Scientists believe that heavy winds–especially when blowing in the opposite direction of the water current–play a large role in forming freak waves. This idea may explain why locations with strong currents (e.g. the Agulhas off Africa and Gulf Stream off the U.S., including the Bermuda Triangle) have a history of reported freak waves.

Published online before print June 22, 2011, doi:10.1098/rsbl.2011.0415AbstractHost manipulation by parasites not only captures the imagination but has important epidemiological implications. The conventional view is that parasites face a trade-off between the benefits of host manipulation and their costs to fitness-related traits, such as longevity and fecundity. However, this trade-off hypothesis remains to be tested. Dinocampus coccinellae is a common parasitic wasp of the spotted lady beetle Coleomegilla maculata. Females deposit a single egg in the haemocoel of the host, and during larval development the parasitoid feeds on host tissues. At the prepupal stage, the parasitoid egresses from its host by forcing its way through the coccinellid’s abdominal segments and begins spinning a cocoon between the ladybird’s legs. Remarkably, D. coccinellae does not kill its host during its development, an atypical feature for parasitoids. We first showed under laboratory conditions that parasitoid cocoons that were attended by a living and manipulated ladybird suffered less predation than did cocoons alone or cocoons under dead ladybirds. We then demonstrated that the length of the manipulation period is negatively correlated with parasitoid fecundity but not with longevity. In addition to documenting an original case of bodyguard manipulation, our study provides the first evidence of a cost required for manipulating host behaviour. © 2010 PhysOrg.com Ladybugs taken hostage by wasps Dinocampus coccinellae wasp. Image credit: Misanthrope/Wild About Britain The study, led by Fanny Maure, a University of Montreal graduate student, looked at exactly what role the ladybug played in the birth and growth of the D. coccinellae. The female D. coccinellae stings the ladybug and lays her egg within the ladybug host. The larva then hatches and eats its way out of the ladybug and within three weeks has hatched out of the ladybugs abdomen. The ladybug, however, is not dead and still very much alive. The grub then spins its orange cocoon within the ladybug’s legs until it grows into an adult. It was believed that the ladybug served as protection to the cocoon as its colors and erratic twitching scares off predators. However Maure decided to test this theory and exposed the wasp cocoons to lacewings. What she discovered was that the unprotected cocoons were devoured but so were 85 percent of the ones protected by a dead ladybug. However, when the cocoon was protected by a still alive ladybug in its zombie state, only about one third of them were eaten.It is still unclear how the ladybug survives and still twitches after the larva has left, but Maure believes that the larva may leave behind some type of venom that enables the twitching within the ladybug. Maure also discovered that the longer the ladybug remains alive, the less beneficial it is for the fertility of the growing wasp.It is believed that this is because the tiny grub is limited to the amount it can eat. If it consumes the ladybug to the point of death, it eats but is less likely to reach maturity without protection. By eating less and allowing the adult ladybug to survive, the grub keeps its protection and reaches maturity, but its development is affected by the lack of food needed for proper development.

(PhysOrg.com) — Advanced imaging technology from the Brookhaven Labs and the European Synchrotron Radiation Facility (ESRF) in Grenoble has revealed an authentic Rembrandt self-portrait in an art authenticity effort involving leading art historians and scientists at the two labs. The hunt for authenticity all began when a private collector showed art historians in Amsterdam a small panel “Old Man with a Beard” from about 1630. The collector wanted to know if it was a Rembrandt.

The publication reported that the detector was able to image the entire painting in about eight hours, in a task that would normally take about 30 days.In general, X-ray Fluorescence (XRF) is considered a key technology for those in the art world, as it highlights pigments concealed beneath the surface, and has previously been used to authenticate works by Van Gogh and Goya, among other famous artists. The tool is especially helpful as it can determine chemical composition in a nondestructive way; the work of art is left intact.Prof Ernst van de Wetering, an art historian at the Rembrandt House in Amsterdam, and head of the Rembrandt Research Project, had worked meanwhile with his team to examine the sketch for authenticity. The imaging results gave scientific support to authentication, which Prof. van de Wetering announced at the Rembrandt House Museum in Amsterdam on Friday.From 1 May to 1 July 2012 the Rembrandt House Museum is staging a special exhibition of research into ten paintings by Rembrandt and his contemporaries using XRF technology.
(Phys.org) —Researchers at the University of Southampton in the U.K. have devised a means for using nanoparticles to cause angiogenesis (the growth of new blood vessels) to speed up or slow down. In their paper published in ACS Nano, the researchers describe how they coated gold nanoparticles with peptides to allow for altering the speed at which new blood vessels develop in specific locations in the body. More information: Manipulation of in Vitro Angiogenesis Using Peptide-Coated Gold Nanoparticles, Dorota Bartczak, Otto L. Muskens, Tilman Sanchez-Elsner, Antonios G. Kanaras, and Timothy M. Millar, ACS Nano Article ASAP. pubs.acs.org/doi/abs/10.1021/nn402111zAbstractWe demonstrate the deliberate activation or inhibition of invitro angiogenesis using functional peptide coated gold nanoparticles. The peptides, anchored to oligo-ethylene glycol capped gold nanospheres, were designed to selectively interact with cell receptors responsible for activation or inhibition of angiogenesis. The functional particles are shown to influence significantly the extent and morphology of vascular structures, without causing toxicity. Mechanistic studies show that the nanoparticles have the ability to alter the balance between naturally secreted pro- and anti-angiogenic factors, under various biological conditions.

The development of new blood vessels is critical while wounds are healing. It’s also important in helping people recover from accidents or who have tissue damaged by disease. Speeding up angiogenesis can help to speed up recovery times. Sometimes however, angiogenesis can progress incorrectly resulting in the growth of tumors. In these instances, doctors would like to slow or stop the angiogenesis process. In this new effort, the research team has found a new way to accomplish both goals with one new treatment option.The new technique revolves around the use of nanoparticles—very small objects generally not found in nature. In this case, the particles created were made of gold. Because nanoparticles can so easily move around inside the body, the thinking was that nanoparticles could be used to deliver drugs to specific areas of the body where they are needed. In this case, the drugs were peptides that have been shown to speed up angiogenesis when appropriate and to slow the process when tumors have developed. The ability to deliver the drug only to areas where they are needed reduces side-effects.In order for angiogenesis to occur, endothelial cells must be activated by the presence of certain molecules engaging with receptor cells. Over time, researchers have developed various drugs to either stimulate or repress angiogenesis by activating the receptor cells or block them. Such drugs have only been useful for a short duration, however, and most often come with unwanted side effects. In this new effort, the team used nanoparticles to carry and deliver such drugs only to the parts of the body that needed them. They found they could target specific receptor cells that allow for focusing on different diseases. Specifically, they developed three types of peptides for delivery via nanoparticles: those that bind and promote cascade growth of blood vessels, those that block receptors cells from receiving signals, and those that serve as a control and do nothing. They report that they were successful in delivering all three types to target areas and that doing so caused the expected changes in angiogenesis rates.

A long-forgotten ‘dinosaur’ bone from a museum cabinet, uncovered to be a Japan’s iconic extinct mammal,Paleoparadoxia(Desmostylia, Mammalia), Royal Society Open Science (2018). DOI: 10.1098/rsos.172441AbstractHere, we report a new ‘discovery’ of a desmostylian fossil in the geological collection at a national university in Japan. This fossil was unearthed over 60 years ago and donated to the university. Owing to the original hand-written note kept with the fossil in combination with interview investigation, we were able to reach two equally possible fossil sites in the town of Tsuchiyu Onsen, Fukushima. Through the interviews, we learned that the fossil was discovered during construction of a debris flow barrier and that it was recognized as a ‘dinosaur’ bone among the locals and displayed in the Village Hall before/until the town experienced a fire disaster in 1954. As scientific findings, the fossil was identified to be a right femur of Paleoparadoxia (Desmostylia), which shows well-preserved muscle scars on the surface. The age was estimated to be 15.9 Ma or younger in zircon-dating. This study shows an excellent case that historical and scientific significances could be extracted from long-forgotten uncatalogued specimens as long as the original information is retained with the specimens. Explore further © 2018 Phys.org The researchers report that the bone was found sometime during the 1950s when workers building a dam came across it. The bone was found near the town of Tsuchiyu Onsen in Fukushima. Archeologists called to recover the fossil described it in a note as a dinosaur femur, and later placed it on a shelf in a museum. It was there on that shelf that the researchers with this new effort found the bone. Testing showed the fossil was from approximately 15.9 million years ago (long past the age of the dinosaurs) and that it was actually the fossilized remains of a Paleoparadoxia femur.Paleoparadoxia resembled the modern hippopotamus—prior research has shown that they were plant eaters and grew to approximately two meters in length. They lived in what is now the Pacific Ocean from 20 to 10 million years ago, with a range running from Alaska to Japan and as far south as Mexico. They were also once thought to be amphibious, but more recent research has shown that they were true marine animals, spending most of their time crawling around on the ocean floor eating.The researchers report their work was made easier by the hand-written note left by the original investigators along with the fossil describing where it had been found. That allowed the researchers to return to the dig site to further investigate its history and to provide material for dating the fossil. Instead of testing the thigh bone directly, the team tested rock from the dig site, which contained datable crystal zircons. After measuring the fossil, the researchers used it to create a 3-D model of the creature when it was alive. They report that due to the condition of the fossil, the recreation was believed to be the most accurate to date.

Twenty floors above the city, as the day closed in, Tom Alter’s rich voice floated amongst the immaculate crystals and some very fine brew. And Eliot. Reflections, a session of tea and poetry held at Le Meridien was an evening for the connoisseurs. A part of the New Perspective event series at the hotel, Reflections seemed to be the most perfect way to kick off, just like the first flush of tea which is believed to be the best. Bits of Mirza Ghalib and Maulana Azad’s poetry mingled with Eliot’s and were accompanied by some perfect cups of tea and savouries. Also Read – ‘Playing Jojo was emotionally exhausting’The poetry was interspersed with talks by tea taster and sommelier Anamika Singh. All the brews tasted through the evening have been blended by her. Putting together green and black tea with flowers and herbs from the Himalayas, Singh has managed to concoct some fragrant brews that is subtle, refreshing and rejuvenates like a dream. Singh believes that the Indian customer has not really woken up to the health benefits of tea and the right way to brew it. There is a need to graduate from a glass of chai to a cup of tea. And to graduate, one needs to learn and the session was quite a start, it is all about what you infuse, says Singh making it clear that teabags just don’t work. Also Read – Leslie doing new comedy special with NetflixAlter took on the session with an idea a Chinese poem puts forth. After the seventh cup of tea in the day, one can attain salvation. He broke the poetry session in to seven segments starting with the first cup of tea in bed and ending it with the last cup of tea before sleep. While the first cup of tea softly nudges one awake, the second cup of tea is believed to drive away the five causes of sorrow. By the third cup of tea life is set in motion and by the fourth – all the wrong of life passes away through the pores. Fifth cup means purification, the 4’o clock bliss, the sixth calls out from the realms of the immortal and by the seventh cup as the day comes to a close, the stirring of the tea makes the world go round. ‘When you have the finest tea, it’s sheer poetry and in sheer poetry there is an unforgettable soothing essence of tea. Reflections is the romance of tea and some great food which helps to unwind and start conversations,’ said Alter. Tea became a refuge of sorts and poetry the perfect companion as songs floated in and out creating the perfect evening. Just as being a poet is a lifetime of work, the right cup of tea imbibes the same passion. And bringing both together could not have been more perfect. All of us has at some time or the other tried writing poetry, perhaps it is also time to try and brew a perfect cup of tea as well.

To mark 70 years of diplomatic relations between India and Iran, an exhibition brought Iranian handicrafts, calligraphy, pottery, metal works and photographs to Delhi. The three-day exhibition organised by Iran Cultural House was held at the Indira Gandhi National Centre for the Arts (IGNCA), New Delhi. It showcased specimens of key Iranian Islamic art oeuvre. The extensive show aimed to introduce traditional crafts of the country, and find common denominators with India.

The technique was invented by ancient Iranian craftspeople, and it then spread to other countries, including India.Many of the works had a intricately-designed blue glaze.’Sofalgari’ or unglazed baked earthenware – also called ‘biscuit pottery’ – was also on display at the exhibition. Examples of coppersmithery, called ‘megsari’, found space in the exhibition as well. ‘Samavars’, or metal utensils to boil tea in most PersianAhomes, could also be seen. Islamic art enthusiasts could also see ‘khatam kari’ work, which is a technique of incrustation, and ‘moaragh’ or wood inlaying. The exhibition closed on July 5, 2019.
Pompeii is one of the most important sites for archaeologists and historians to research the Roman empire and its culture. Pompeii was a medium-sized town, with around 11,000 inhabitants. However, it is characterized by its multicultural demographics, thriving community and sophisticated infrastructure. The nearby port of Pozzuoli enabled the development of a strong economy, particularly centered around trade.Villa of the Mysteries in Pompeii seen from above. Photo by ElfQrin CC BY-SA 4.0The economic stability and the presence of merchants from all parts of the empire ensured for a strong presence of sex trade. Sex historians have thoroughly researched the walls of estates that served as brothels such as inns, taverns and lunch counters.What also plays a major role in their research is the graffiti that sometimes graphically listed details connected to sex-work, therefore serving as one of the most important historical sources.Roman painting from Pompeii, early 1st century AD, most likely depicting Cleopatra VII, wearing her royal diadem, consuming poison in an act of suicide, while Caesarion, also wearing a royal diadem, stands behind her.The pictures on the walls usually present fair skinned women with intricate hairstyles, accompanied by tanned and athletic men. There are three potential reasons for these images.They could have served as a visual cue for stronger arousal. It could also be that the scenes were a pictorial menu of different services one could get in a brothel. Lastly, they might have been guides for inexperienced customers who would frequent the premises.Pompeii and Herculaneum, as well as other cities affected by the eruption of Mount Vesuvius. The black shading represents the general distribution of ash, pumice and cinders. Photo by MapMaster CC BY-SA 3.0Much of the graffiti found on the walls is very graphic. It details specific employees and their skills, sexual advice, and prices for specific acts one could seek out.Related Video: Mummified Cats and Beetles Discovered in Ancient TombStudies of this graffiti have revealed that the sex workers had names of exclusively Greek origin. Their names were sometimes descriptive and told the story about either physical characteristics or the function of a sex-worker. The names of male sex workers are also featured.Purpose-built brothels featured cubicles with a permanent foundation for the bed, as in this example from the Lupanar at Pompeii.As freeborn women were not allowed to have sex outside of marriage, it is almost certain that their only customers were men. The practice of homosexual intercourse was indeed nothing strange for the ancient Rome.The only rule was that the citizens who were higher up in rank could not take on a submissive role during intercourse. In general, the sex trade was not frowned upon and it was central in maintaining the institution of marriage. It was believed that the wife’s role was solely to provide a male heir.Roman fresco with banquet scene (detail) from the Casa dei Casti Amanti (IX 12, 6-8) in Pompeii.Seeking pleasures from a wife was thought to be immodest and not respectful to the woman. Therefore, the husbands would fulfill their fantasies in one of the many brothels around. Sex work was not illegal, but adultery was, so it was a normal practice to pay in exchange for physical love.However, sex-workers had it far from easy. They worked in stone cells, usually without any windows and with a curtain instead of a door.Fresco of couple in bed.Most sex workers were slaves, so they did not have any choice but to obey their masters. The attitude towards slaves in ancient Italy was not favorable — it ranged between indifference at best to open violence.They were cut off from the rest of the world and usually moved only around the estate they worked in. They were usually under the control of procurers who owned the rights to them and their bodies, and who may have provided only the most basic necessities for their slaves.Read another story from us: Clever Marketing: Ancient Greek prostitutes wore sandals that printed a message in the ground reading, “Follow me”At bigger towns and cities there were some women that worked the streets on their own. The percentage of solo prostitutes is rather small, and it consisted either of freed slaves or very poor freeborn women.
November 20, 2009 5 min read Problem Solvers with Jason Feifer You can’t claim to have lived in New England until you’ve gotten through a winter. The same could be said for e-commerce sites. Whatever track record you’ve had the rest of the year, the real proof that your online business is viable comes some time after the holiday crunch. Did you handle the high volumes without sacrificing customer care? Did you not only deliver the goods for current customers but also attract new ones? Did you, your staff and website emerge intact? Is your accountant smiling?If the answer to these questions is generally “yes,” then you should be smiling, too. But here’s my advice: Think of the holidays as a stress test for your organization. You won’t always be dealing with these kinds of volumes, but the best practices you embrace now will pay dividends the rest of the year.In that spirit, here are some tips for the holiday season–and beyond:Use incentives to keep a steady flowOne of the most important safeguards against getting overwhelmed is to level out the volume spikes that can catch your organization off guard. The steadier the flow of traffic to your site, the better. Conversely, if 90 percent of your customers place their orders on Dec. 22, you’re going to look unprepared no matter how much preparation you’ve made.Begin by working out a set of incentives that will get your customers buying early. Possibilities include free gift wrapping, free shipping, two-for-one offers, coupon codes for later purchases, and, especially popular in today’s economy, merchandise discounts and promotions. Then make sure your customers are aware of the offers by highlighting them on your home page. You can also e-mail your most valued customers, as long as you don’t wear out your welcome. Finally, monitor the results to see what your customers are responding to. That knowledge will help you rev up sales during slow periods throughout the year.Clearly communicate the true costThe trend in e-commerce sites is to eliminate as many hidden costs as possible. Transparency is especially important during the holiday season, when customers have even less patience for unhappy surprises. Customers report that hidden shipping costs are the most frequent irritant–especially when those costs are unexpectedly high and only appear at the final stages of checkout. That ploy can lead to shopping cart abandonment–the merchandise is at the “register,” but the customer has departed.Instead, let customers know as soon as possible in the process what shipping will cost. Most of us know what it costs to mail a package, so keep those costs in line with customer expectations–or go one better and offer free shipping as an option. Some customers will always want more expedited shipping, but all will appreciate the opportunity to get standard shipping for free. And again, that’s true not only during the holidays, but throughout the year.Take customer support seriously–but let’s chatThe time has long passed since the days when an e-commerce site could hide from its customers by not responding to queries. Phone calls are usually best, but not every online company has the resources to handle them, especially during the holiday crunch.What to do? Resist the urge to bring in people who can answer the phone, but lack the expertise to truly represent your store. A badly handled call is worse than an unanswered one. Instead, consider online chat. The medium isn’t as personal as the phone, but skilled representatives can conduct five or 10 chats at once–and customers will quickly recognize whether the people at the other end know what they’re doing. Of course, e-mail can also be effective as long as you’re diligent about responding quickly–an e-mail black hole is worse than no e-mail at all. And what if you’re truly underwater from customer queries? Apologize, get a number and a good time to call–and call back.Use “heat map” technology to track what clicksHere’s another place the holiday stress test can serve you well in the coming year: tracking what people actually do on your site. Companies like CrazyEgg, and Clickdensity offer services that can show you how people are navigating your website, with the ability to experiment with new designs that are more effective. While the holiday season is no time for a major redesign, you can make quick fixes, and then use this invaluable data to make bigger changes later on.Improve checkoutOne reason people have flocked online for their holiday shopping is that when they’re ready to check out, they’re always first in line. So make sure you’ve exceeded customer expectations during those final, crucial mouse clicks. The key is to reduce the number of hoops customers must jump through, while giving them different options to pay. For example, the checkout process should securely retain customer data so that people don’t have to re-enter their information with each purchase. You should also offer a variety of payment options so that shoppers can use their preferred payment method, including a buy now, pay later plan, which is especially important in these cash-strapped times.When your customers check out, they should also feel safe. Over the past few years, many people became online shoppers only after they overcame their fear of making online transactions. Once they had a good experience, they returned online for more. In that sense, every successful online transaction is a win for our industry as a whole. So do your part: Make sure your customers are feeling safe by giving them a truly secure method of paying.

Apple Has a Patent for That.Then, using GPS when a signal is available and the iPhone’s own onboard sensors and accelerometer data when it’s not, the technology could purportedly tracks a driver’s whereabouts by dropping digital breadcrumbs in relation to that parking spot.To activate directions, Apple imagines that users might initiate a vocal command to Siri — upon which an audio and/or visual navigation would appear.The patents would seem to bolster Apple’s marked play for car integration — including its CarPlay system, which syncs users’ iPhones with a built-in dashboard display and whose launch was recently pushed into next year.Related: Apple’s Latest Patent Tracks Temperature, Perspiration and Heart Rate — in Your Headphones Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right.

If we are ever going to live on Mars, we first have to figure out how to create oxygen on the red planet’s surface. This weekend, entrepreneurs, designers, coders, inventors, storytellers and creatives from all over the world will come together in a 48-hour hackathon to offer solutions to this and other big-picture problems.NASA and IBM are collaborating to host the International Space Apps Challenge. More than 10,000 people are expected to participate in more than 130 locations across the globe.The hackathon starts at 9 a.m. on Saturday, April 11, wherever you are in the world and ends at 11:59 p.m. on Sunday, April 12, local time. Teams work together on open-source problems.Related: Elon Musk Wants to Colonize Mars in Order to Fend Off Human ExtinctionThe challenge topics fall into one of four main categories: earth, outer space, humans and robotics. The problems being tackled this weekend are quite intentionally orders of magnitude more grandiose than the sorts of daily annoyances that most of us mere mortals spend our time sorting through.For example, one challenge NASA is asking hackers to think about is wearable fashion technology for astronauts to wear in space. One challenge wants a team to find the most exciting pictures of the universe. And another involves making a 3-D printer for food in space.Related: NASA Takes a Step Toward Mars With Test LaunchCliche as it may sound, the idea for the International Space Apps Challenge was born on a hotel napkin in San Francisco, and is a product of the belief that “innovation is often bottom-up, decentralized and unpredictable,” according to the Challenge’s website. It’s the sort of naively utopian, kind of crazy, and totally fascinating daydreaming that just really might change the world we live in.Listen to NASA astronaut Catherine “Cody” Coleman talk about the challenge in the video embedded below.

Opinions expressed by Entrepreneur contributors are their own. 4 min read January 6, 2017 Entrepreneur is on the ground at this year’s Consumer Electronics Show. Check back for highlights from the event as well as insights from thought leaders and innovators. My first day at CES was insane. I saw so much technology at CES, it was mind-numbing. This show is an overload — in the very best way. It’s a mob! I don’t know what took me so long. If you’re not at CES, you’re out of it.The booths that were packed and loud were very interactive. They had to be to stand out in this tech-obsessed crowd. The products upstairs — like 3D printers and smart watches — weren’t exactly revolutionary. These were more or less proven moneymakers. It was corporate.But the atmosphere downstairs was different. It was intense. The startups there are battling it out to eventually make it big and move upstairs, which I can’t help but love. They’re out there in the aisles, hustling. Fighting tool and nail to get noticed. These are my people. When something was hot, it was obvious, because the cameras were out. Some booths were three or four persons deep the entire day.Related: 9 Must-See Products at CESThese were the products that caught my eye the most:1. Holographic technology from Kino-mo Image Credit: Stephen KeyHolograms are here! And they are amazingly cool, especially Kino-mo. The company creates holographic technology to be used in advertising. This London-based company’s one-sentence benefit statement: Take your logo to the moon. And they definitely did that at CES.The booth I checked was for Hypervision, Kino-mo’s “holo-displays.” You can think of them like holograms, because that’s what they look like but less costly. That said, so far the holo-displays have been used by brands like Aston Martin, Intel, and Samsung for advertising.Someone on the team had been smart enough to mount the holograms high enough, so that they could easily be seen from a distance, which meant their booth was packed all day long. I must have walked by six times.The visuals themselves were vividly bright and looked as if they were floating. You had to pull your phone out.2. Sam’s Curious Cars from SAM Labs Image Credit: Stephen KeyI really dug SAM, an innovative new toy from UK-based startup SAM Labs that “allows kids to start building and creating in a really fun and intuitive way,” Morten B. Hagen, head of sales and marketing, told me. Using SAM’s small wireless building blocks and app, children can build and program their own inventions.When Hagen said, “You can think of it like Lego from the future,” within less than 15 seconds, I was sold. That’s a great benefit statement!Related: Artificial Intelligence Now Has a Voice, But Security Challenges Loom3. Magic Instruments high-tech guitarImage Credit: Stephen KeyDeveloped by a Julliard-trained musician, I was told anyone can play it. Officially, on their marketing materials, it’s “quick to play and fun to learn.” Interesting! The company graduated from Y Combinator in winter 2016 and raised $415,000 in pre-orders on Indiegogo.4. 3Dvarius high-end electric violinImage Credit: 3D VariusThis product was wild. Taking several hundred hours to hand-make in France, it marketed itself as a “combination of the latest technologies with ancient violin-making skills.” Customized and adopted to the user’s body, it was eye-catching and even more fun to watch the gentleman doing the demo wail on it. Related: No More Bad Hair Days With This Smart HairbrushI’ve been to a lot of trade shows but none that have been so interactive.

You’re not alone.A strange bug affecting some devices running iOS 11.1 prevents people from typing the letter “i.” Reddit user TheCravin reported the problem over the weekend, noting that when some people try to type the letter “i” on a device running the public version of iOS 11.1, the keyboard suggests a different character like the “A,” “#” or “!,” followed by the “the Unicode character for ‘Hey I can’t read this'” — a box with a question mark.”I thought that was weird, but then I saw a tweet where someone clearly tried to type ‘I,’ and it instead showed the ‘A’ operator and then the question mark character,” TheCravin wrote. “When I tried to copy and paste the content of the tweet, my paste fixed it and just showed the letter ‘I.'”Several users chimed in on that thread and on Twitter saying they, too, were experiencing the issue.Anyone else finding this glitch on iOS???
