More Secure Optical Communications Via Antisqueezed Light

first_img Explore further Citation: More Secure Optical Communications Via ‘Antisqueezed’ Light (2006, October 10) retrieved 18 August 2019 from Physicists use nanostructures to free photons for highly efficient white OLEDs Enter researchers Tatsuya Tomaru and Masashi Ban from the Hitachi Advanced Research Laboratory in Japan. Recently, they figured out that more secure optical communications can be achieved using “antisqueezed” light. Their work is described in the September 13, 2006, online edition of Physical Review A.“Antisqueezed light is tolerant of loss and amplification,” Tomaru told “It is well suited to optical communication.”Antisqueezing, rather nonintuitively, is one side effect of a process called squeezing, which (also nonintuitively) is not the mechanical action its name implies. Rather, understanding squeezing and antisqueezing begins by understanding the quantum nature of light – that light is inherently grainy, made up of basic units, or “quanta,” called photons. And photons, like other particles, like to retain some mystery. A photon will allow either its position or its momentum to be measured with high precision – but not both. This limitation is known as the Heisenberg Uncertainty Principle.That said, squeezed light – and by extension antisqueezed light – is defined by fluctuations in the precision of the photons’ measured position and momentum. When the fluctuation (i.e. the error) of the measured momentum is “squeezed,” the fluctuation of the measured position must, in accordance with the Heisenberg Uncertainty Principle, become inflated, or “antisqueezed.”So how can this make optical communications more secure? Mathematically speaking, when squeezed light is transmitted, the larger fluctuation – the antisqueezed component – dominates, and the squeezed component regresses to the natural fluctuations light experiences in a vacuum. But the antisqueezed component resists that pull; it is always beyond the vacuum fluctuation, even after loss and amplification. The result is a signal that is far more loss-tolerant. As a result, there are far fewer lost pieces for eavesdroppers to collect.Tomaru and Ban assume real light signals that are encrypted prior to transmission, with the intended receiver equipped with the proper key to correctly un-encrypt the signal. An eavesdropping receiver would not know this key, and would be unlikely to correctly guess it. This is a common way to secure a transmission. Using antisqueezed light adds an extra measure of security.“Antisqueezing is essential to differentiating between legitimate receivers and eavesdroppers,” said Tomaru. “Eavesdropping would be very difficult under these conditions.”Citation: T. Tomaru and M. Ban, “Secure optical communication using antisqueezing.” Phys. Rev. A 74, 032312 (2006)By Laura Mgrdichian, Copyright 2006 PhysOrg.comcenter_img Using light to transmit information – optical communication – is the basis of several technologies, most commonly fiber-optic cables, which are used in imaging and telecommunications. But sending information securely using light requires minimizing and compensating for loss as the light propagates between transmitter and receiver. And in the area of security, there is always room for improvement. This document is subject to copyright.

Fujifilms FinePix Real 3D W3 digital camera lets user capture images in

first_imgWith built-in lenses, image sensors for capturing 3D images, Fuji stands apart from its competition by processing 3D in hardware while most, like Sony, perform post-processing in software. With a list price of $500, like most professional picture-taking 2D cameras, the FinePix Real 3D W3 will launch in early September 2010, alongside new Sony models. Fujifilm unveils 3D digital camera Citation: Fujifilm’s FinePix Real 3D W3 digital camera lets user capture images in 3D (2010, August 23) retrieved 18 August 2019 from 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. After a successful launch of the worlds first 3D camera in September of ’09, the makers of Fujifilm developed a smaller, lighter, more compact version, weighing only 8.5 ounces with battery. The FinePix Real 3D W3 digital camera has a Minin HDMI 1.4 interface for immediate 3D viewing of pictures and videos taken at resolutions as high as 720p on practically any 3D TV with stereographic glasses, or special laptops and PC desk monitors. Among some of the other added benefits of the new version are an improved screen, 3x optical zoom, and Auto 3D mode.On the flip side, by using the 3.5 inch LCD display, or the optional 3D viewer, special glasses aren’t needed at all to view images. There’s also an added option to transform the images in lenticular prints through a unique printing process, that will be available in the UK. (c) 2010 ( — With 3D HDTV’s exploding in today’s market, Fujifilm has launched a new point-and-click camera with 3D photo capability. With 3D TV innovators like Sony, Panasonic and Samsung, the camera comes at a time perfect for the 3D revolution and can be used with or without special glasses to view. President for Fujifilm North American Imaging and Electronics Divisions, Go Myazaki, spoke of affordable 3D TV’s on the rise, during a press event Tuesday at the Museum of Natural History saying “we’re looking to leverage that.” Moving beyond the hobbyists, the FinePix Real 3D W3 digital camera is an attempt to increase interest in the mass market. Though, it’s not to be said a second, 2D camera is needed after the purchase of the FinePix Real 3D W3. Two cameras in one, users can switch modes via the built-in button, to shoot and display normal, 2D photos. One special feature, the proprietary processor, allows users to take two pictures at one time. More than a 2D, there’s a lot of creative freedom with this newer version.last_img read more

Two teams independently find that adding vibration helps couple light to graphene

first_img It’s very common and relatively easy to use light or electronics as a means of carrying data—what’s difficult is using both in the same device. The problem is getting photons converted to electrons and vice-versa. Recent research has found that using two dimensional graphene as a means for doing so might be feasible, but up until now, scientists have only been able to achieve efficiencies of approximately 2 percent. In this new effort, both teams were able to increase the efficiency to 50 percent by causing the graphene surface to vibrate in a tunable way as it was being hit with light.Graphene is used because of its unique honeycomb structure that allows for long duration plasmons—quasi-particles which have an oscillation property—that can be tuned to desired frequencies. Current methods of coupling that rely on shaping the graphene into ribbons have been found to be highly inefficient due to scattering at the edges (and that the approach does not allow for tuning patterns.)To reduce scattering, both teams applied a vibrating force to the graphene sheet. The Saudi team attached an actuator—the Spanish team added piezoelectric material as a base to the graphene. Both resulted in the same outcome, namely, causing the electrons in the surface of the graphene to vibrate as they were being struck by photons—tuning the vibrations allowed for rousing the conduction electrons into plasmons, which thereafter could be processed by electronic components.The results by both teams are just the first step in creating mechanisms that are able to join electronic functions with photons which may one day lead to devices such as exotic super-sensitive chemical detectors, new kinds of photovoltaic cells or general purpose nano-optoelectronics devices. Citation: Two teams independently find that adding vibration helps couple light to graphene (2013, December 12) retrieved 18 August 2019 from ( —Two teams of researchers, one working in Saudi Arabia, the other in Spain, have discovered independently that adding vibrations to a graphene surface allows for more efficient conversion of photons to plasmons. In their papers, both published in the journal Physical Review Letters, each team describes how they found that causing a two-dimensional graphene surface to vibrate (using two different methods) led to a huge increase in light energy being coupled.

Evidence of intraspecific agonistic interactions in Smilodon populator (Carnivora, Felidae), Comptes Rendus Palevol (2019). DOI: 10.1016/j.crpv.2019.02.006 A team of researchers with members affiliated with several institutions in Argentina has found evidence that suggests the canine teeth of the saber-toothed cat were strong enough to puncture the skulls of other members of the same species. In their paper published in the journal Comptes Rendus Palevol, the group describes their study of saber-toothed cat fossils and what they learned from them. Saber-toothed kittens may have been born with thicker bones than other contemporary cats The saber-toothed cat was a formidable predator, of that there is little doubt—the species living in South America, Smilodon populator, grew to weigh 220 to 400 kg, was approximately 120 centimeters long, and had canine teeth that grew to be 28 centimeters in length. They lived during the Late Pleistocene Epoch (from 11,000 to 126,000 years ago). Paleontologists have believed that the canines of the big cats were too thin to puncture bone, but now that theory appears to be under fire. The researchers with this new effort report evidence of what appears to be a hole in an S. populator skull that was made by the canine of another S. populator.The researchers report that they have actually found two S. populator skull fossils with holes in them consistent with a canine piercing. Both of the skulls were found in different parts of what is now Argentina, and both had a single hole between the eyes, but a little farther back—very similar to hole punctures in many modern cats (cheetahs, leopards and jaguars)—such cats, especially males, often get into serious fights, sometimes resulting in the death of one of the combatants. The researchers found that an S. populator canine fit perfectly into the hole in the skull. They tried the same test with other long-toothed animals and were not able to find any with teeth that fit into the holes. They even checked to see if the holes could have been made by a kick from a hoofed animal and were not able to find any that matched. The only fit was another saber-toothed cat canine, which suggests that the holes were made as the cats were fighting over territory, food or a potential mating partner. © 2019 Science X Network Citation: Saber-toothed cat fossils provide evidence of canines able to puncture a skull (2019, June 3) retrieved 18 August 2019 from This document is subject to copyright.

Briton Krishna Maharaj framed by Columbian drug lord

first_imgKrishna Maharaj, a self-made millionaire who moved to Florida in the mid-1980s, spent 15 years on death row for the killing of his business partner Derrick Moo Young, of Jamaican-Asian descent, and his son Duane before his sentence was appealed and commuted to two life sentences in 1997. He has always maintained he is innocent. The 75-year-old’s lawyer Clive Stafford Smith, of human rights organisation Reprieve, says evidence suggests the execution style murders at a downtown Miami hotel in 1986 were ordered by Escobar, the former head of the infamous Medellin cartel. His defence team are now hoping new evidence at the three-day hearing will be enough to persuade Florida circuit court judge William Thomas to overturn Maharaj’s conviction. Also Read – Pro-Govt supporters rally as Hong Kong’s divisions deepenA former American pilot who flew cocaine shipments for the cartel told the court on Monday that during a conversation with Escobar at his Colombian ranch in 1986 he heard the drug lord admit to having killed ‘los chinos’ (the Chinese) at a downtown Miami hotel. Maharaj had gone to the hotel that day and waited in room 1215 for a business associate who, he says, never turned up. His legal team claims Maharaj was lured there to leave his fingerprints at the scene, and left before the Youngs arrived. Stafford Smith claims Maharaj, who was suing Young for fraud at the time, was framed to cover up Colombian cartel murders.  Also Read – Pak Army ‘fully prepared’ to face any challenge: Army spokesmanBut prosecutors claimed he lay in wait for Young, 53, and his son Duane, 23, confronted them about missing cash – then shot them both dead. Maharaj was arrested while eating dinner at a Miami restaurant later that evening with his wife, Marita. A retired DEA agent, Henry Cuervo, also testified that the initial 1986 investigation by Miami police ignored ‘red flags’ pointing to the involvement of Colombian drug traffickers, including documents that indicated the Moo Youngs were involved in money laundering. Brenton Ver Ploeg, a lawyer who investigated a $1.5 million life insurance policy held by the  Youngs, told the court that financial records suggested the family company was involved in illegal activities including drug money laundering. He said he stored the documents in the case for 28 years because he felt there was ‘something wrong’ with the case, and was surprised that investigators never asked to see his files until years later. Prosecutors sought to block Monday’s testimony saying the defense case consisted of hearsay.last_img read more

Irresistible emotions World Cup fever come to Darjeeling

first_imgDarjeeling: It was Asha’s first ever tryst with Darjeeling that she had heard about from her father and grandfather, not quite the one that she was born and brought up in. Asha, a Class 9 student of a Hill school, was used to a Darjeeling where rallies, slogan shouting and bandhs were a daily affair. The days of unrest usually paved way for agitations marred with violence. But today, the scenario is very different. On Saturday, thousands of students along with people from all walks of life, took to the street with flags and cheered, sang and danced to celebrate the spirit of Darjeeling and the teams they support for the upcoming football World Cup. The frenzy gripped the Queen of Hills that was labeled as Darjeeling — the World Cup Town 2018 by the citizens. Also Read – Heavy rain hits traffic, flightsThough the world will ring in the football World Cup on June 14, Darjeeling kick started the frenzy on June 2 with a mega event organised by Darjeeling North Point School Alumni Association (DNPSAA,) along with various other organisations, NGOs and citizens of the region.”We are celebrating the spirit of Darjeeling along with our love for the game. We want people to know that Darjeeling is peaceful and the nicest place in the world. We want people from all over the world to visit Darjeeling,” stated Ajoy Edwards, Vice-President, DNPSAA. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedVeteran footballers, students from different Hill schools, locals and even tourists joined in the parade that went around Chowrasta and down Nehru Road to return to where it began. The marchers shouted slogans and danced to football-themed songs. The parade was led by footballer Nirmal Chettri of FC Goa.The town was decorated with separate team flags, roadside walls painted up and billboards put up giving the town which is witnessing a huge tourist onrush, a festive look. The day saw cheer-leading competitions, garage sales by Shanker Foundation; dance fiesta by Edith Wilkins Street Children’s Trust; bike and scooty rallies from Kurseong hosted by MARG; mountain bike rally; BMX stunts; cosplay, b-boying; face painting; nail art; hair do; musical performances and beat boxing. The bike rally from Darjeeling to Kurseong and back was a major attraction. Even women riding scootys, mountain bicycles were part of it. Aces — the Super Bike club from Siliguri also joined them. “I had heard from my father and grandfather that Darjeeling used to be the safest, most peaceful and cosmopolitan place in the country. It was a great place to live in. In the past, I had never seen anything to connect the town with such claims. However, today (Saturday) was different. Hope we get back all the goodness of good old Darjeeling soon,” said Asha. The award for the cheer leading competition was won by Gyanodaya Niketan School, Darjeeling. An award for best decorated area of the town (World Cup theme) was also announced. 10-year-old Pratham Thapa, an MTB rider, was also felicitated. “The event is not just about fun. It has an underlying cause. With the participation registration amount we will buy an ambulance for our project the Clinic on Wheels. This is an ambulance fitted with a mobile lab and ECG machine. The mobile clinic will visit far flung areas every week and provide medical test facilities to the marginalized at highly subsidized costs,” stated Deven Gurung, president, DNPSAA. The organisers also want to revive the golden era of football in the Hills including the famous Brigade of Gurkhas Gold Cup football tournaments.”Even back home celebrations have not yet commenced. Darjeeling has beaten us. I’m happy to see that England too has quite a fan following in Darjeeling,” stated Neil, a tourist from England.last_img read more

Monsoon to hit North Bengal in 3 days

first_imgKolkata: The Monsoon is all set to hit North Bengal within the next three days but for the South Bengal districts, it might take some more time. There may be some pre-monsoon rains in the South Bengal districts including Kolkata. Various South Bengal districts received moderate to heavy rainfall on Monday morning disrupting normal life. According to the Regional Meteorological Centre at Alipore, South Bengal districts including the city may witness thunderstorms as a result of pre-Monsoon rains within the next 48 hours before the advent of Monsoon in the state. Also Read – Heavy rain hits traffic, flightsAccording to a senior official of the weather office, a circulation which was staying over Bangladesh could trigger a storm in some parts of North Bengal. A favourable atmosphere for rain has already been prevailing in the Himalayan regions. Various South Bengal districts including North 24-Parganas, Nadia, Murshidabad, Hooghly, Howrah and parts of the city received moderate to heavy rainfall on Monday morning. “Local clouds have started forming due to the impact of approaching Monsoon. It will trigger mild thunderstorms mainly in the North Bengal districts. However, there is hardly any possibility of squall in the city and the South Bengal districts. Cloud masses which have been floating in from the neighbouring areas for the past few days are not potent enough to initiate a squall in the Southern parts,” a senior official of the weather office said. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedIt may be mentioned here that Monsoon currents have already reached Tripura and parts of central Assam and Bangladesh. The currents have started advancing towards North Bengal. It is expected that Monsoon currents will arrive in North Bengal by the middle of this week.However, it is difficult to predict the date of the arrival of Monsoon in South Bengal and Kolkata as there is no clear indication to the weather office. This is because there is no low-pressure or any cyclonic circulation over the Bay of Bengal. The Monsoon is not likely to hit this week as there is no such system prevailing over the Bay of Bengal.last_img read more

The deadline for admission has been extended till August 20.”Wherever there are vacant seats, be it in pass or degree courses, the admission process will continue till August 20. The secretary of the undergraduate (UG) council at CU has been directed to send necessary instructions to the concerned colleges,” Chatterjee said, after attending the 103rd foundation day celebration of Asutosh College in Hazra. Also Read – Rain batters Kolkata, cripples normal lifeHe reiterated that admission will be strictly on the basis of merit and students have to pay the requisite fees to the bank accounts of the colleges in which they are seeking admission. According to sources, Chatterjee held a meeting with Chief Minister Mamata Banerjee about the status of vacant seats in colleges.It may be mentioned that out of 1.3 lakh seats in various CU affiliated colleges, around 40,000 are still lying vacant. The earlier deadline for admission was July 10 and the university found that seats were lying vacant at Surendranath College, Jaipuria College, South City College, Dinabandhu Andrews College, Sris Chandra college, North City College and Seth Surjamal Jalan College to name a few. The colleges had already written to CU, urging it to extend the dates for admission. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedProdded by Chief Minister Mamata Banerjee, the state Higher Education department has instructed all colleges in the state to admit students through the online mode, so that they no longer need to turn up physically for the purpose.The police also cracked the whip and arrested a number of people, including students, for being involved in extorting money to grant admission.Chatterjee in the past had often been vocal about the tendency among students in crowding a handful of educational institutions in the state. He had warned the colleges of strong action if they admit students beyond their intake capacity. Asked about his response to the reintroduction of admission tests in Jadavpur University, Chatterjee said, “It (JU) is an autonomous institution. The government won’t interfere in its functioning.”JU had recently witnessed a hunger strike by students in protest against the decision of the authorities to scrap admission test in six Humanities subjects. A section of teachers had also lent support to the students. The university finally yielded to the pressure and reintroduced entrance tests for the 6 subjects last week.last_img read more

Shift in venue Presidency decides to conduct Convocation at Nandan

But Presidency University is an educational institution, not a factory,” the minister asserted.V-C Lohia expressed her doubts over holding the convocation on the varsity campus while speaking to the reporters after being stopped at the gate. “There are so many students in the university and only a section of them are involved in such activities (protests). I don’t want tomorrow’s (Tuesday) Convocation ceremony to get affected in any way,” she said. The V-C made it clear that she would not seek police help in this regard.”We are not against the convocation ceremony as it involves the prestige of Presidency. We want it to be held smoothly. However, it is the responsibility of the varsity authorities to ensure its safe conductance,” one of the agitating students said.last_img read more

Indulge in hydro therapy to cure body pain

first_imgThinking of relaxing with a new kind of therapy? Then get yourself treated with hydro-therapy, which involves using water for providing relief from pain.“The therapy encompasses a broad range of approaches and therapeutic methods that take advantage of the physical properties of water, such as temperature and pressure, for therapeutic purposes, to stimulate blood circulation and treat the symptoms of certain diseases,” said Dr Ashish Davalbhakta, founder of Pune-based Aesthetics Medispa, a cosmetic surgery, cosmetology and wellness centre.  Also Read – ‘Playing Jojo was emotionally exhausting’“Bath temperatures typically range from 92°F (33 degrees Celsius) to 97°F (36 degrees Celsius), so as not to cause injury to the patients,” he added. Hydro-therapy involves a range of methods and techniques like water jets, underwater massage and mineral baths.The jets shoot water at precise chakras on the body at specified time periods, cleansing and opening them.“Hydro-therapy seeks to produce vasodilation and vasoconstriction. These cause changes in blood flow and associated metabolic functions. The benefit of hydro-therapy is that it reduces muscle tension and pain, rehabilitates injured muscles, boosts the immune system, encourages detoxification and relives stress,” added Davalbhakta. Sea salts and Epsom salts, or magnesium sulfate, both commonly used in the beauty  industry, are also used as they contain minerals that can help enhance the skin. The magnesium in Epsom salts can reduce inflammation, while sulfates flush out toxins. This helps in exfoliation, invigorates, cleanses and regenerates the skin.last_img read more

Facial exercise may help you look more youthful

first_imgFacial exercises may significantly improve appearance and reduce some visible signs of ageing, a study suggests. Researchers found that a 30-minute daily or alternate-day facial exercise programme sustained over 20 weeks improved the facial appearance of middle-aged women, resulting in a younger appearance with fuller upper and lower cheeks.This is the first scientific study to test the premise of facial exercise improving appearance.”Now there is some evidence that facial exercises may improve facial appearance and reduce some visible signs of ageing,” said Murad Alam from Northwestern University in the UK. Also Read – Add new books to your shelf”The exercises enlarge and strengthen the facial muscles, so the face becomes firmer and more toned and shaped like a younger face,” said Alam, lead author of the study published in the journal JAMA Dermatology.”Assuming the findings are confirmed in a larger study, individuals now have a low-cost, non-toxic way for looking younger or to augment other cosmetic or anti-ageing treatments they may be seeking,” he said.As the face ages, skin loses elasticity and fat pads between the muscle and skin become thinner. Also Read – Over 2 hours screen time daily will make your kids impulsiveThe fat pads, which fit together like a jigsaw puzzle, give the face much of its shape.As skin becomes saggy, the thinning fat pads atrophy and slide, causing the face to “fall down.””But if muscle underneath becomes bigger, the skin has more stuffing underneath it and the firmer muscle appears to make the shape of the face more full,” said Emily Poon, an assistant research professor at Feinberg.”Muscle growth is increasing the facial volume and counteracting the effects of age-related fat thinning and skin loosening,” Poon said. Study participants, middle-aged women 40 to 65 years old, underwent two sets of face-to-face 90-minute training sessions from a facial exercise instructor.At home, they continued to do these exercises for a total of 20 weeks. For the first eight weeks, they did the exercises daily for 30 minutes. From nine to 20 weeks, they did the same exercises every other day for 30 minutes a session.Participants learned and performed 32 distinct facial exercises, each one for about a minute.”One is The Cheek Lifter: Open mouth and form O, position upper lip over teeth, smile to lift cheek muscles up, put fingers lightly on top part of cheek, release cheek muscles to lower them, and lift back up. Repeat by lowering and lifting the cheeks,” researchers said.”Another exercise is The Happy Cheeks Sculpting: Smile without showing teeth, purse lips together, smile forcing cheek muscles up, place fingers on corners of the mouth and slide them up to the top of the cheeks, hold for 20 seconds,” they said.Two dermatologist raters looked separately at 19 features of the face and rated all of those at three different time points: at the beginning, at week eight and at week 20.The raters found that upper cheek and lower cheek fullness, in particular, was significantly enhanced as a result of the exercises.In addition, the raters estimated average patient age decreased over the course of the study. It started at 50.8 years, dropped to 49.6 years at eight weeks and then to 48.1 years at 20 weeks.last_img read more

Dont snack mindlessly

first_imgSnacking is not a mindless pursuit. And unlike universally thought, it is not devoid of any benefits. In fact, if done right, it can be a perfect way of incorporating important, often missed out nutrients to our daily diet. Nutritionists lay down the rules of healthy snacking: Ensure that you choose to eat only those snacks that are made from right ingredients. This in fact is an accurate way of ensuring that the nutrients we need are added to our diet. A few of my favourite ingredients include kaala Channa, nuts and seeds, olive oil and whole grains. Also Read – Add new books to your shelfKala Channa, a nutrition powerhouse, delivers a lot of fibre that helps regulate our blood sugar and is also loaded with nutrients that help save us from seasonal disorders by boosting our immunity. The easiest way to get a stockpile of multiple vitamins and minerals, even difficult to find trace minerals is to eat snacks that have nuts and seeds added liberally to them. Besides they also deliver high levels of essential fatty acids (EFAs), wholesome fibre, and much needed good quality protein (with all essential amino acids). Also Read – Over 2 hours screen time daily will make your kids impulsivePick up snacks made in olive oil, as this is the smartest way to ensure omega 3 and to correct the good versus bad fat imbalance in our diet. It is the best way to keep our digestion humming along, keep constipation and cravings away. A snack made with whole grains is the best way to add nutrition to our diet. Make snacking a conscious activity. Snack mindfully, not mindlessly. It is essential that we not only snack smart but we also pick and select our snack smartly. Avoid snack packs that don’t deliver what is promised on the face of their pack. Look out for promises and phrases like Fat-Free, Low in Calories, High in Protein. Don’t take them on face value. All it takes is flipping the pack to the back and reading all ingredients, their proportions, style of making to understand the health and calorie quotient of the snack you are picking up. It is always better to opt for truly baked, healthy and wholesome snacks as they will actually be good for you. In fact, one of the best ways to lower fat consumption is to switch from deep fried snacks to baked snacks as they will help you keep both the calories and fat consumption down easily. Don’t think of snacks as extras. Instead, consciously work healthy bites into your diet, and make some smart snacks a part of your food plan for the day. This way they will work for you constructively. Finally, always focus on eating snacks that deliver something extra (yes more than just satisfaction and calories). Focus on clean label. Consumers and regulators continue to put new pressures on food manufacturers, asking for even more information on the label. Consumers want to know the origin of their food. Food transparency strategies are now critical elements of the industry. Many varieties of snacks and breads sold in supermarkets have taken a huge hit in recent years. Their part of the myriad products are struggling as consumers shift to more health and wellness foods. Despite this, more gluten-free, and clean-label baked formulations are cropping up in stores.last_img read more

If LeBron leaves for LA he would be better off going to

first_imgIf LeBron leaves for L.A., he would be better off going to the Clippers over the LakersFollowing the Cavs Finals loss to the Warriors, the speculation immediately started regarding LeBron James future and if he could jettison the Cavs for the second time in search of greener pastures. Some have speculated one destination for James could be Los Angeles. When L.A. and James come up, most assume he would bolt for the Lakers, but Colin thinks the Clippers are the far better option.If the Clippers added James to Chris Paul and DeAndre Jordan, and could entice Paul George to join, they would have a far better group than anything the Lakers could put together. And if James could manage to win a title with Clippers, having already brought a championship to Cleveland, it would only enhance his legacy. And LeBron is keenly aware of his legacy.Ultimately, Colin thinks James will stay in Cleveland, but if he does leave again, he would be better off calling Jerry West than Magic Johnson.Mayweather/McGregor will be a great pay day, but an awful fightFloyd Mayweather and Conor McGregor have offically confirmed their highly anticipated boxing match that has been rumored for the better part of a year. The fight will almost surely shatter all existing pay-per-view records and make both fighters a ton of cash, but will the actual fight be any good?Colin doesn’t think so, primarily because, in order to make it happen, McGregor has foregone any tactical advantage he might have by agreeing to a straight boxing match. It’s like Steph Curry agreeing to a Slam Dunk contest against LeBron James. Both are big names, but you don’t need a crystal ball to predict how it would end.The same applies to McGregor and Mayweather in a boxing match. It will be a legendary pay day, but a forgettable fight.“It’s a sanctioned payday. It’s Evel Knieval with no chance of crashing.”Guests:Dana White –  UFC President joins the show to discuss finalizing the Mayweather/MGregor fight; why they decided on a boxing match; why the negotiations weren’t the most difficult he has undertaken; and why he thinks the fight will be competitive.De’Aaron Fox – NBA Draft prospect from Kentucky is in-studio to discuss the pre-draft process; his experience with individual team workouts; what the NCAA Tournament win against UCLA meant to him; and if it matters to him toSeth Joyner – Former NFL Pro Bowl linebacker is in-studio to discuss Odell Beckham missing voluntary workouts; if it matters in the locker room; and his own eperience with locker rooom dysfunction under Rich Kotite.last_img read more
