3D nanotube assembly technique for nanoscale electronics

first_img From 2-D to 1-D: atomically quasi ‘1-D’ wires using a carbon nanotube template (PhysOrg.com) — For the past several years, researchers have been trying to take advantage of carbon nanotubes’ good electrical properties for future nanoscale electronics applications. One of the biggest challenges in this area is finding ways to arrange and assemble the nanotubes into 3D configurations for carrying current in nanoscale devices. Most recently, a team of physicists and engineers from the Electronic Materials Research Institute at Northeastern University in Boston, Massachusetts, has demonstrated a technique for assembling nanotubes using an applied electric field. Using this method, the researchers could assemble single-walled carbon nanotubes into 3D structures by coaxing the nanotubes into deep nanoholes in a porous alumina template. An average of one nanotube per hole was vertically assembled, and, by sweeping the 0.32cm2 area, more than one million holes were filled with nanotubes.“The greatest significance of this technique is that it provides the potential to manufacture, at a high rate and on a large scale, three-dimensional single-wall carbon nanotube electrical interconnects, without the need for high-temperature synthesis,” Srinivas Sridhar, Director of the Electronic Materials Research Institute, told PhysOrg.com.To achieve this nanotube assembly, the researchers attached a positive electrode to the bottom of a silicon template, which the aluminum template went on top of. Then they manually swept a negative electrode over assembly sites, pushing negatively charged nanotubes into the holes in the aluminum template. This process of using an electric field to move charged objects is called electrophoresis. Similarly, a process called dielectrophoresis, in which a non-uniform electric field moves charged or uncharged objects, also assisted in orienting the nanotubes toward the holes.After assembling the nanotubes, the researchers sputtered a 15-nm-thick gold layer on top of the alumina template, touching the tops of the nanotubes. This layer completed an electrical connection between all the nanotubes reaching the surface of the template, with electric current traveling through the nanotubes between the gold and silicon layers. On control samples without nanotubes, no current was observed between the two layers, confirming that the nanotubes had carried the current.By not requiring high temperatures, and providing the ability to cover centimeter-scale areas in a short time, the new assembly technique has useful advantages over other nanotube assembly techniques. The method could also integrate well into existing silicon platforms, which could be used in microelectronics, field emission displays, electronic memory devices and solar cells.“The next step in nanoscale electronics is to integrate the 3D carbon nanotubes architectures with current CMOS technology and create hybrid systems,” Sridhar said. “The holy grail of nanoscale electronics is to completely replace CMOS technology by monolithic carbon nanotubes devices.“Scaling down the nominal feature size makes more space available on a chip to hold more transistors and other types of devices,” he added. “Shrinking process geometries means better performance and lower costs.”More information: Electronic Materials Research InstituteCitation: Gultepe, Evin; Nagesha, Dattatri; Casse, Bernard Didier Frederic; Selvarasah, Selvapraba; Busnaina, Ahmed; and Sridhar, Srinivas. “Large scale 3D vertical assembly of single-wall carbon nanotubes at ambient temperatures.” Nanotechnology 19 (2008) 455309 (5pp).

Active Shutter 3D Technology for HDTV

first_imgPanasonic 3D Full HD truck The problem with anaglyph 3D is that it strains the eyes, and can cause headaches and nausea in some people. Others have a dominant eye, and find it difficult to see the image as three dimensional.A newer process for 3D in the cinema uses a special screen and polarized glasses. In this system images for the left and right eye are rapidly alternated, and the glasses pick up the appropriate image for each eye. A similar technique has now been introduced for high definition LCD televisions by LG Electronics in South Korea and Hyundai in Japan. The system, known as X-Pol, projects the different images in the even and odd horizontal lines of the video, and the polarized glasses sort it all out for the viewer. The original 3D experience of movies depended on the viewer wearing stereoscopic green and red glasses. The illusion of 3D in the image came from superimposed green and red images taken from slightly different angles. Each eye saw only one image, and the viewer’s brain combined them to give the illusion of three dimensions. 3D movies using this technology, called anaglyph 3D, can be viewed on any TV, as long as the viewer wears the glasses. Panasonic executive Peter Fannon said the new high definition 3D televisions will give viewers an experience just like being there, rather than watching it on TV.Panasonic will be releasing some Full HD 3D models later this year, with Sony’s version coming on the market later. Buyers of the new TVs will also need 3D-compatible Blu-ray disc players. The glasses will be supplied with the TV sets. There is no information yet on the prices of these televisions. Anaglyph 3D glasses. Image: Wikipedia. LG Electronics 47LH50 3D LCD TV (PhysOrg.com) — Sony and Panasonic have recently announced a new technology, called “active shutter” for producing the experience of 3D on high definition TVs.

By watching these images through special LCD glasses that are timed to open and close the right and left lenses in synchronization with the alternating images, the viewer is treated to exciting 3D realism. Image: Panasonic Now Sony and Panasonic have introduced an “active shutter” technique for high definition plasma and LCD TVs. The viewer still has to wear polarized glasses, but in this system the glasses have LCD active shutters that are synchronized with signals from the TV. The shutters rapidly block the right and left eye views alternately so each eye receives the correct image. The new system gives higher resolution than X-Pol because in active shutter technology each eye sees all the lines in the video, whereas in X-Pol each eye sees only half the lines.

He said the reason why they adopted that concept is because they are actually mimicking natural vision. Images just seem more realistic, vivid, natural and comfortable, unlike watching a cellphone or notebook computer all day, he remarked, “When I put this on,” he added, in placing the Glyph on his face, “the amount of depth is incredible….feels like I am looking out a window.”A Virtual Retinal Display uses a micromirror array and combination of optics to reflect an image directly onto the retina; the “screen” becomes the back of the eyeball. The picture comes across as sharp and vivid, and 3D images are exceptionally clear. One of the FAQ listed on the company’s site asks, “Is it safe?” Yes, is the given answer. “The light source is simply a low powered Light Emitting Diode (LED) – something like you would see at the end of a keychain light. The micromirror array and optics together create the unique image.”Looking into the device, the user sees an image that appears as an 80-inch screen eight feet away from the user. That translates, according to Avegant, to about a 45-degree field of view.Tang described his company as a startup intent on bringing out a “portable media platform.” According to the company, “Glyph can plug into any HDMI source and display any current content natively. This means sources from an XBox to a Playstation to a MacBook to an iPhone to an Android may be used while content from Blueray DVDs to video games to streaming movies can be watched.” More information: www.avegant.com/avegant-introd … -display-technology/ Dynamically reconfiguring images with flexible OLED FlexCam (w/ Video)center_img (Phys.org) —Ann Arbor, Michigan-based Avegant on Wednesday announced that a Kickstarter campaign will launch on January 22 on behalf of its product Glyph, a $499 headset. Glyph is also to go on display at the upcoming Consumer Electronics Show in Las Vegas from January 7 to 10. The shipped version will have one HDMI/MHL cable, and onboard battery power. The Glyph is a headset that integrates video display and audio experiences in a flip-down form factor. The result is a wearable display doubling as a set of headphones. The form factor, however, is not the most notable aspect of the product.

ITARTASS claims Russian cosmonauts have found sea plankton on outside of International

first_img © 2014 Phys.org Finding sea plankton on the outside of the ISS would be remarkable, as the outside of the station is of course exposed to space—a hostile environment, to say the least. NASA officials reported that they were aware that Russian cosmonauts were conducting experiments on the exterior of the space station (primarily on windows known as illuminators), but were unaware of what they entailed. They note that cosmonauts have conducted such experiments as recently as this past week. The same officials report that they have not heard the results of any findings regarding the experiments from the Russian scientists directly, and thus, cannot comment on what the Russians are claiming. One scientist with NASA, Lynn Rothschild, suggested that if the claims turn out to be true, the plankton likely made its way to the ISS aboard a space station module.Reports of the sea plankton findings have come, ITAR-TASS reports, from Vladimir Solovyev, chief of the Russian ISS orbital mission—he’s also reporting that the type of plankton found is not native to the parts of Russia where spacecraft are launched—he theorizes that air currents could have pushed the plankton to the station (plankton is known to make its way into the atmosphere). The findings, he continues, confirm that organisms can live on the outer surface of the space station, something Russian scientists have apparently been studying for over a year—though he didn’t actually come right out and say that the specimens found were still alive. He also reports that the outside of the space station is covered with material from spacecraft engines that is emitted as they come and go. Of concern are the illuminators, which now need to be polished.

NanoSuit Researchers use nanocoating to allow for electron microscopy of living insects

first_img Up till now, researchers have had to kill insects and dry them before putting them under an ESM—that is because such microscopes require the specimens to be viewed in a vacuum (to keep the electron beam from scattering). In this new effort, the research team reports that they have figured out a way to apply a very thin clear coat to a specimen that prevents dehydration and thus allows specimens to be imaged as they exist naturally—representing a major step forward for research involving studying biological samples or living creatures at very close range.The coating used by the team was an artificial material that mimics an extracellular substance, in this case, a solution consisting of surfactant polyoxyethylene sorbitan monolaurate, aka TW20, which was subjected to plasma or electron beam irradiation, causing it to polymerize. The result, they report was a very thin (50 to 100 nanometers) layer, or coating, which they immediately dubbed a nanosuit. Insects coated with the material were able to survive up to two hours in a high vacuum the team reports. In addition to preventing dehydration, the coating also prevented damage to the insects from the electron beam.The team used the coating on several different kinds of insects and report that imaging them via ESM was done successfully and that most of the insects survived. They note that the coating remained intact (hard on the outside, soft on the inside) even if the insects moved. They also pointed out that coating the insects was easy to do—they just dipped the bugs in a solution or let a drop of it fall onto them and then wiped off the extra.The team plans to continue testing the impact of the nanosuit on the insects that have been coated, to find out if it causes harm that is not obvious, such as damage to DNA.

DOI: 10.1098/rspb.2014.2857AbstractAlthough extremely useful for a wide range of investigations, the field emission scanning electron microscope (FE-SEM) has not allowed researchers to observe living organisms. However, we have recently reported that a simple surface modification consisting of a thin extra layer, termed ‘NanoSuit’, can keep organisms alive in the high vacuum (10−5 to 10−7 Pa) of the SEM. This paper further explores the protective properties of the NanoSuit surface-shield. We found that a NanoSuit formed with the optimum concentration of Tween 20 faithfully preserves the integrity of an organism’s surface without interfering with SEM imaging. We also found that electrostatic charging was absent as long as the organisms were alive, even if they had not been coated with electrically conducting materials. This result suggests that living organisms possess their own electrical conductors and/or rely on certain properties of the surface to inhibit charging. The NanoSuit seems to prolong the charge-free condition and increase survival time under vacuum. These findings should encourage the development of more sophisticated observation methods for studying living organisms in an FE-SEM. (Phys.org)—A team of researchers with members from several institutions in Japan has found a way to allow for using scanning electron microscopes (ESM) on living insects—encase them in a nanosuit. In their paper published in Proceedings of The Royal Society B, the team describes the coating they used and how effective it was when used on a variety of insects. .

Lobbying in Capitals corridors

first_imgAs per recent surveys, Delhi is among the biggest five cities of the world. The ancient city of Delhi has been transformed from a sleepy government town to a megacity in under three decades. This has completely changed the ethos of the city. Once a town dominated by courteous government officials and small-scale businessmen, Delhi today has changed into a power centre.Once a city becomes a megacity, its residents must adapt themselves in order to survive. Every megacity has its own rules. A resident must know how to abide by these rules. These places are melting pots for regional or global immigrants. Hence ambitions rule supreme.

General Court of the EU orders bloc to remove Hamas from terror

first_imgThe General Court of the European Union ruled on Wednesday that the inclusion of the group was not based on a “concrete examination” of Hamas’s acts but on “imputations derived from the media and the internet”. Hamas has been contesting its inclusion on the list, maintained since it was created in 2001. The court said the move was technical and was not a reassessment of Hamas’ classification as a terrorist group. It said a funding freeze on the group would continue for the time being. Also Read – Pro-Govt supporters rally as Hong Kong’s divisions deepenThe foreign office of the EU reacted by sayng “We respect the General Court of the European Union’s judgement delivered on Wednesday annulling measures against Hamas, namely the designation of Hamas as a terrorist organisation and the freezing of Hamas’ funds. This legal ruling is clearly based on procedural grounds and it does not imply any assessment by the Court of the substantive reasons for the designation of Hamas as a terrorist organisation. It is a legal ruling of a court, not a political decision taken by the EU governments. The EU continues to uphold the Quartet principles”. Also Read – Pak Army ‘fully prepared’ to face any challenge: Army spokesmanIt added “The EU institutions are studying carefully the ruling and will decide on the options open to them. They will, in due course, take appropriate remedial action, including any eventual appeal to the ruling. In case of an appeal the restrictive measures remain in place”. On December 27, 2001 the Council of the European Union adopted a common position and a regulation to combat terrorism. These measures require the freezing of the funds of those people and entities included on a list adopted and regularly updated by Council decisions. The same day the Council adopted its first decision establishing that list. By this decision the Council included Hamas on the list and has maintained them on that list ever since. The General Court said “The case-law of the Court requires that an EU decision to freeze funds is based not on factual elements that the Council may have derived from the press or the internet, but on elements which have been concretely examined and confirmed.”last_img read more

Sept exports fall 2433 in 10th straight monthly dip

first_imgContracting for the 10th month in a row, India’s merchandise exports dipped 24.33 per cent in September to $21.84 billion, mainly due to steep fall in shipments of petroleum products, iron ore, and engineering goods amid tepid global demand.The imports too shrank 25.42 per cent to $32.32 billion in September on yearly basis, thus narrowing the trade gap to $10.47 billion from $14.47 billion recorded in the same month of 2014. Exports in September 2014 were valued at $28.86 billion. The cumulative exports during the first half of 2015-16 have been valued at $132.93 billion versus $161.39 billion in the same period of last year. Exports were down 17.36 per cent yera-on-year in the first half of 2015-16. Also Read – Punjab & Sind Bank cuts MCLR by up to 20 basis pointsAs per the data released by the Commerce Ministry, the trade gap or trade deficit during April-September 2015-16 has narrowed to $67.99 billion as against $72.69 billion in the same period last fiscal. The data further showed that oil imports during September were valued at $6.62 billion, down 54.53 per cent year-on – year. Oil imports during April-September stood at $48.128 billion which were 41.58 per cent lower than that of $82.378 billion in the corresponding period last year.  On export front, shipments of petroleum products shrank 60.35 per cent to $2.44 billion while that of iron ore declined by 40.37 per cent to 9.47 million. A sharp decline in exports of engineering products was also witnessed in September. The shipments declined by 22.81 per cent to $5 billion from $6.5 billion in the year ago period.  Also Read – ‘The great gold bull market has begun’The decline in exports in September is the steepest since March 2015 when the shipments shrunk by 21.06 per cent. Expressing disappointment over the September numbers, Federation of Indian Export Organisations (FIEO) President S C Ralhan said the decline of 17.6 per cent in first six months of the fiscal will put enormous pressure even in realising the export figure which India achieved in 2014-15. “As against seven sectors which were in positive out of 30 for which disaggregated data is available for August, the number of sectors has further compressed to six only for the month of September,” he said.Ralhan however, expressed the hope that export numbers in coming months would be better following cut in interest rate by the RBI and encouraging IIP and manufacturing data of August. The data showed that non-oil imports during September were estimated at $25.697 billion which were 10.68 per cent lower than $28.76 billion in the same month of 2014.last_img read more

Use Facebook just for posting likes to ward off depression

first_imgIf you are young and love Facebook, keep it to just “liking” and minimise your virtual circle of friends to cut the upcoming depression risk.According to researchers, the social networking site can have positive and negative effects on the levels of a common stress hormone in teenagers.The team found that having more than 300 Facebook friends increased teenagers’ levels of cortisol while those who only posted “likes” on their Facebook friends to encourage them actually decreased their cortisol levels.  Also Read – ‘Playing Jojo was emotionally exhausting’“We were able to show that beyond 300 Facebook friends, adolescents showed higher cortisol levels. We can imagine that those who have 1,000 or 2,000 friends on Facebook may be subjected to even greater stress,” explained Professor Sonia Lupien from University of Montreal.“While other important external factors are also responsible, we estimated that the isolated effect of Facebook on cortisol was around eight percent,” Lupien noted. Lupien and her colleagues recruited 88 participants aged 12-17 years who were asked about their Facebook use, number of friends, self-promoting behaviour, and the supporting behaviour they displayed towards their friends.  Also Read – Leslie doing new comedy special with NetflixAlong with these four measures, the team collected cortisol samples of the participating adolescents. Other studies have shown that high morning cortisol levels at 13 years increase the risk of suffering from depression at 16 years by 37 per cent. While none of the adolescents suffered from depression at the time of the study, Lupien could not conclude that they were free from an increased risk of developing it. “We did not observe depression in our participants. However, adolescents who present high stress hormone levels do not become depressed immediately; it can occur later on,” Lupien emphasised.  Some studies have shown that it may take 11 years before the onset of severe depression in children who consistently had high cortisol levelsThe study is one of the first in the emerging field of cyberpsychology to focus on the effects of Facebook on well-being. “Developmental analysis could also reveal whether virtual stress is indeed ‘getting over the screen and under the skin’ to modulate neurobiological processes related to adaptation,” the authors noted in a paper published in the journal Psychoneuroendocrinology.last_img read more

Motherly affection can combat depression in kids

first_imgA depressed mother’s stress can pass on to infant before his or her life begins in many ways. But according to a new study, parenting strategies can combat the negative impacts of maternal depression on an infant.Stress can pass through the placenta to negatively impact the foetus in ways that manifest after birth such as birth weight, brain development and increased susceptibility to various ailments, said lead author Elisabeth Conradt from University of Utah in the US in a study. Also Read – ‘Playing Jojo was emotionally exhausting'”We were curious about whether maternal behaviour could ‘buffer’ the child against the effects of maternal depression, and if this buffering could be observed at the level of the infant’s epigenome,” Conradt added in the study published in Child Development.This study is the first to demonstrate that certain forms of maternal care-giving can have such an effect.The team worked with 128 infants of women with self-reported symptoms of depression and obtained DNA from the infants through cheek swabs and cortisol – a hormone released in response to stress, levels from their saliva. Also Read – Leslie doing new comedy special with NetflixEach infant participated in three two-minute face-to-face play episodes with their mothers. The first play episode required normal play between mother and infant, the second episode required that the mothers be unresponsive to their infants and the third episode was a reunion episode where mothers were allowed to interact again.Maternal sensitivity, recorded every 30 seconds, was assessed using four scales.Greater levels of maternal sensitivity were related to lower levels of cortisol, the study found.”Many mothers struggle with depression but interact quite sensitively with their infants. In these instances, the mother may be ‘turning on’ certain genes that we think allow infants to manage stress in adaptive ways,” Conradt stated.last_img read more

Colins Blazin 5 NFL Week 2

first_img Advertisement Every Friday, it’s time for Colin’s Blazin’ 5. Colin had a rough Week 1 (2 – 3), but he’s feeling confident heading into Week 2 now that he’s seen the teams with his own eyes. He’s ready to make the house pay up.Don’t listen to your buddy Teddy “The Nostril”. Listen to Colin, and cut out some time on Monday so you can make a trip to the bank to unload your stacks of cash.Without further delay, here’s Colin’s NFL Week 2  Blazin’ 5.Kansas City (+2.5) vs. Houston – Colin loves getting the 2.5 here. Sure, the Texans looked great last week. Get over it, it was the Bears and Smokin’ Jay Cutler. KC has the QB and coaching edge, and have won 11 straight regular season contests. Tight end Travis Kelce is going to be a massive matchup problem for the Texans. Take KC and the points. Road dogs pull the outright upset. 24 -17 KC. 2. Titans (+5.5) vs. Detroit  –  5.5 points here is a gift. Detroit scored 30 on the road against Indy’s high school caliber defense in Week 1. Big deal, everyone is gonna put up 30 on the Colts this year. The Titans have a real defense, and held Adrian Peterson to a meager 31 yards rushing in Week 1. Marcus Mariota has been great on the road in his brief career (10 TD’s 1 Int). Derrick Henry and DeMarco Murray will run it against one of the worst rushing defenses in the NFL to keep it close. Titans cover. 24 – 23 Detroit.3. Atlanta (+4.5) vs. Oakland- Everybody loves the Raiders this year, including Colin. But, they’re still young, and trailed for most of Week 1 in New Orleans. Colin doesn’t love Matty Ice on the road, but he loves Atlanta’s weapons. 4.5 is too many points to give Atlanta, even on the road. Colin likes the Birds, the points and the outright upset. 27-20 Falcons.4. Indy vs. Denver (-6) –  6 is a big number to swallow, but the Colts defense is so bad it’s inappropriate for children under the age of 18. Their two best players, cornerbacks Vontae Davis and Darius Butler are questionable. No es bueno. This one could get ugly. The Broncos D is stacked with elite talent and a rabid pass rush. Andrew Luck doesn’t stand a chance with a weak supporting cast. Colin loves a well rested Denver to demoralize the Colts. 27-10 Broncos.5. Dallas vs. Washington (-2.5) –  Dak Prescott starts his first road game against a salty Washington team that was embarrassed by the Steelers at home last week. The Cowboys aren’t the Steelers, and Dak Prescott isn’t Big Ben. The Redskins have a terrible run defense that will keep it close, but the hostile environment in DC is too much for Prescott and the ‘Boys. Washington by a couple of field goals. Give the 2.5. Washington 26 – 20.That’s The Blazin’ 5 for Week 2 in the NFL.Also, make sure you download, listen and subscribe to Colin’s Prediction Podcast, which will be available this Saturday morning, and every Saturday through the end of the football season.

Colin The Patriots are the greatest dynasty in pro sports history Video

first_imgSuper Bowl 51 ended like another fairy tale for the New England Patriots. Tom Brady and Bill Belichick captured their fifth Super Bowl championship by erasing a 25-point second half deficit against the Falcons by authoring the greatest comeback in the history of the Super Bowl.Today in The Herd, Colin looked at the Patriots extended run from a historical perspective, and as far as he’s concerned the Patriots are the greatest dynasty in the history of professional sports.It’s not just the 7 Super Bowls and 5 titles that impress Colin with the Patriots, it’s that they’ve sustained their level of success over close to 15 years in a league that’s designed for parity, and to bring the top teams back to the pack.“It’s the greatest dynasty in pro sports history.”I don’t really count college. In baseball, you can buy the players. The NBA is driven by stars. Jimmy Johnson’s Cowboys, Chuck Knoll’s Steelers, Bill Walsh’s 49’ers had seven or eight bedrock players.I say ‘The Steelers,’ you name the players. I say ‘The Niners,’ you name the players. I say ‘Jimmy Johnson’s Cowboys,’ you name the players.This is Law & Order, man. It’s a revolving door of mostly slightly above average players, and it’s going nowhere really fast.”Here’s the video of Colin’s full rant:.@ColinCowherd on Patriots: “It’s the greatest dynasty in pro sports history” pic.twitter.com/zEAz37uXl5— Herd w/Colin Cowherd (@TheHerd) February 6, 2017last_img read more

VIDEO Micd up Joey Bosa thoroughly enjoyed terrorizing Nathan Peterman during his

first_imgBuffalo Head Coach Sean McDermott’s panic move to start rookie Nathan Peterman over Tyrod Taylor was easily the worst single coaching decision of the NFL season, to date. Peterman fell on his face and threw 5 first-half interceptions en route to a 54-24 bludgeoning at the hands of the Chargers.Joey Bosa was mic’d for the game and captured sound during his day long campaign of terror against the Buffalo rookie. Peterman’s beating looks and sounds even worse when you hear it on field level. Bosa also stripped Tyrod Taylor for a fumble that was returned for a TD.This kid never had a chance. Bosa is a beast.last_img read more

VIDEO Tom Brady pleads the 5th at conference QA when asked if

first_imgThe Patriots have gone from CIA level secrecy to a knitting circle in terms of public leaks over the past year. The power struggle soap opera between Tom Brady and Bill Belichick has devolved from an in-season exposé, to Brady sending repeated signals in the offseason that Bill Belichick isn’t the boss of him.Today, during a Q&A at the Milken Institute Global Conference by his hand selected personal interviewer Jim Gray, Brady continued to stir the pot with more comments that he knew where sure to fuel the rumor mill.When asked by Gray if he felt appreciated by the organization considering all that he’s achieved, Brady responded, “I plead the fifth.”When Gray followed up by asking Brady if he was happy at work, Tom replied, “I have my moments.” Coming on the heels of Gisele’s similar comments from Tom vs. Time, and a number of other public affronts to Belichick during the offseason, these remarks are the latest salvo in Brady’s revolt against Bill’s dictatorship. Tom’s barely trying to hide it here.Vegas still has the Patriots set to win the most games of any team in the NFL next season, so maybe none of will matter in the end.The video from the conference was posted by Boston area sports journalist Tom Curran. It’s not much to look at, but you can hear Brady’s answers loud and clear.Tom Brady was asked today at the Milken Institute Global Conference if he feels appreciated by the Patriots.
