By Dialogo November 17, 2011 The United States reserves the right to retaliate with military force against a cyber attack and is working to sharpen its ability to track down the source of any breach, the Pentagon said in a report made public on Tuesday, November 15. The 12-page report to Congress, mandated by the 2011 Defense Authorization Act, was one of the clearest statements to date of U.S. cybersecurity policy and the role of the military in the event of a computer-borne attack. “When warranted, we will respond to hostile attacks in cyberspace as we would to any other threat to our country,” the report said. “We reserve the right to use all necessary means – diplomatic, informational, military and economic – to defend our nation, our allies, our partners and our interests.” Hostile acts, it said, could include “significant cyber attacks directed against the U.S. economy, government or military” and the response could use electronic means or more conventional military options. Cyberspace is a particularly challenging domain for the Pentagon. Defense Department employees operate more than 15,000 computer networks with 7 million computers at hundreds of locations around the world. Their networks are probed millions of times a day and penetrations have caused the loss of thousands of files. The report said the Defense Department was attempting to deter aggression in cyberspace by developing effective defenses that prevent adversaries from achieving their objectives and by finding ways to make attackers pay a price for their actions. “Should the ‘deny objectives’ element of deterrence not prove adequate,” the report said, “DoD (Department of Defense) maintains, and is further developing, the ability to respond militarily in cyberspace and in other domains.” Key to a military response is being able to quickly identify the source of an attack, particularly challenging due to the anonymous nature of the Internet, the report said. In an effort to crack that problem, the Pentagon is supporting research focusing on tracing the physical source of an attack and using behavior-based algorithms to assess the likely identity of an attacker, the report said. U.S. security agencies also are grooming a cadre of highly skilled cyber forensics experts and are working with international partners to share information in a timely manner about cyber threats, including malicious code and the people behind it, it said. Before moving to offensive action, the United States would exhaust all other options, weigh the risk of action against the cost of inaction and “act in a way that reflects our values and strengthens our legitimacy, seeking broad international support wherever possible,” the report said.
Rivalries make college football special.Coaches, players and fans alike circle one or two games on their calendar each year as “must-win” games — not because of rankings or standings, but out of a longstanding and passionate dislike for another school. For some, it would be OK if their team lost every other game if only they beat that school.The names really say it all. Every year, Pittsburgh and West Virginia throw down in the Backyard Brawl. Utah and BYU wage an annual Holy War. Georgia and Georgia Tech engage in Clean, Old-Fashioned Hate.Whether between teams in the same conference, the same state or even the same city, almost all of college football’s rivalries share a common bond: They make geographic sense.USC’s rivalry with Notre Dame stands out because of how seemingly random it is: 2,103 miles separate Notre Dame Stadium from the Los Angeles Memorial Coliseum. The teams have never played in the same conference — Notre Dame football has seen no need for conference affiliation at all. What then does a Catholic school of fewer than 12,000 students in northern Indiana have in common with a secular institution of 36,000 grads and undergrads in the heart of the nation’s second-largest media market?The origin of the rivalry is equally odd. Gwynn Wilson, USC’s equivalent to an athletic director in 1925, went with his wife to Lincoln, Neb., in November of that year to spend Thanksgiving watching Notre Dame play the Nebraska Cornhuskers.The Trojans themselves were in the midst of an 11-2 season in which they played all but one game at the Coliseum and were searching for a more nationally prominent rival. The Fighting Irish were a prime candidate, having gone undefeated the previous season, which was capped off by a 27-10 victory over Stanford in the 1925 Rose Bowl.At this point, the line between truth and fiction begins to blur. Legendary Notre Dame coach Knute Rockne — whose life inspired the movie Knute Rockne, All American, starring, among others, Ronald Reagan — is said to have been reluctant to agree to an annual series with the Trojans because of the long-distance travel required.That’s when the women stepped in. Wilson’s wife got to chatting with Rockne’s wife and convinced her that a biannual trip to the sunny West Coast was an improvement upon the usual pilgrimage to freezing Nebraska.Naturally, Rockne was convinced by his wife, and the teams squared off for the first time ever in Los Angeles the following December. This Saturday the Trojans and Irish will play for the 83rd time in their history.It’s not just the distance between the schools, however, that makes the series unique. Notre Dame fills its schedule each year with games against teams from coast to coast because it doesn’t belong to a conference.In the 1980s, for example, the Trojans’ were far from the Irish’s most fearsome opponents. USC didn’t win a single game against Notre Dame from 1983 through 1995. Meanwhile, the Irish went to nine major bowl games during that span and won the 1988 national title.The games Notre Dame fans most looked forward to then were the team’s showdowns with the Miami Hurricanes, which reached their dramatic peak in the 1988 game dubbed “Catholics vs. Convicts,” featuring a pre-game brawl between the teams. The series was called off two years later, however, and was only renewed again last year in the Sun Bowl.The longevity of the USC-Notre Dame series, along with its prominence on the national stage, is what sets it apart.The two programs have won a combined 22 national championships (11 each) and 14 Heisman trophies (seven each). They’ve had more players drafted into the NFL (USC is first with 472, Notre Dame second with 469) than any other school. Both are in the top eight in all-time winning percentage.The series has produced some of the best moments in the history of college football.Notre Dame fans fondly recall the 1988 game in which the No. 1 Irish beat the No. 2 Trojans 27-10 in Los Angeles on their way to the program’s last national championship.The 1977 “Green Jersey Game” is also a happy memory for the Golden Domers. That year Notre Dame wore its traditional blue uniforms during warmups before switching clothes and charging out of the tunnel in special green jerseys followed by a giant Trojan horse. Led by quarterback Joe Montana, the Irish won 49-19.USC supporters can claim “The Comeback” from 1974, in which the Trojans trailed 24-0 with 10 seconds remaining in the first half and rallied to win 55-24. Running back Anthony Davis scored four of his 11 career touchdowns against Notre Dame in that game.More recently, Matt Leinart converted a 4th-and-9 pass to Dwayne Jarrett at Notre Dame Stadium in 2005 on the Trojans’ dramatic late drive. Leinart won the game with a one-yard quarterback sneak on the famous “Bush Push” play, giving the Trojans a 34-31 victory.It’s moments like those that make USC and Notre Dame’s rivalry stand out as truly special. “Sellin’ the Sizzle” runs Wednesdays.

It’s not likely engineers and biologists will run out of inspiration from biology anytime soon. The source is infinite.We start with a quote from a commentary in PNAS by Michael H. Bartl about work on “butterfly inspired photonics” that applies to all bio-inspired research. The word “design” is key to the story:Biological systems have been an infinite reservoir of inspiration ever since humans started to develop tools and machinery. Just as early scientists and engineers attempted to mimic birds and fish in the development of flying machines and submarines, today, new technologies find their inspiration from biology, such as gecko feet, antireflective eye lenses, iridescent insects, and water-repellant surfaces. Incorporating biological systems and concepts into technological design can happen in several ways: inspiration, mimicking, and replication. In the latter, entire organisms or body parts are directly used, and their structural features are replicated into another compound. Examples include 3D photonic crystals from iridescent beetle scales or antireflective microlens arrays from insect eyes. In contrast, in bioinspiration and biomimicry, a biological function or activity—rather than the organism itself—is converted into an artificial, human-made material or device. In PNAS, England et al. report an optical micrograting array inspired by a photonic structure found in iridescently colored butterfly wings. The authors demonstrate a micrograting array that not only mimics the unique diffraction properties of the biological structure with reversed color-order sequence, but also can be designed to tune these optical properties.Here’s more news about some of the latest applications coming out of biomimetics research. The first examples show that robotics is especially keen on biological solutions.Inchworm robot : “Robot that moves like an inchworm could go places other robots can’t” (PhysOrg). Made in South Korea, it’s “simple, lightweight, and quiet.” It may be useful for “rescue and reconnaissance missions, but also as a potential material for smart structures and wearable devices.”Muscle bots : “‘Muscles’ Triggered by Electricity Could Power Tiny Robots” (Live Science). Fibers that expand and contract like muscles could lead to electronics that could automatically rewire themselves—even though the force in the artificial material is 1,000 times weaker than the power of human muscle.Downhill gecko robots : “What Goes Up Must Come Down: Biologists at UC Riverside show that geckos alter foot orientation during downhill locomotion” (UC Riverside). No one has really figured out how geckos move downhill till these scientists studied it. They found that the forelimbs act as brakes, the hind limbs as stabilizers. “The research has applications in robotics, specifically in how robots can be designed to move up and down complicated surfaces.” Incidentally, geckos on the Australasia side of the Wallace Line grow about twice as big, PhysOrg reports, but scientists as yet do not know why, other than differences in predators.Bird bots : “Running robots of future may learn from world’s best two-legged runners: birds” (Oregon State U). “Although birds are designed primarily for flight, scientists have learned that species that predominately live on land and scurry around on the ground are also some of the most sophisticated runners of any two-legged land animals.” They’re even better than humans at leaping over obstacles without losing their speed or focus. “The running robots of the future are going to look a lot less robotic,” robotics expert Jonathan Hurst said. “They will be more fluid, like the biological systems in nature. We’re not necessarily trying to copy animals, but we do want to match their capabilities.”Sparkling silver fish LED reflectors : “Mechanism behind nature’s sparkles revealed” (BBC News). The silvery colors seen in schools of sardines and herring are due to disordered arrays of nanoscopic crystals in the scales that exploit light. This is also true in unrelated species, like beetles, butterfly wings and birds. Dr. Nicholas Roberts likes looking at nature for ideas we never thought of; this is why he finds science exciting. “He added that the structures could be copied to produce highly reflective surfaces to, for example, manufacture reflectors to make LED lights more efficient.”Why sea turtles are plump : “Plump turtles swim better: First models of swimming animals” (University of Wisconsin-Madison). Modeling a biological system often precedes application. Engineers at U of Wisconsin were surprised to find that plump turtles swam better than lean ones. “We can literally design animals now and ask how are they going to function, just like a car or a rocket ship,” researcher Warren Porter said.Bird feather anti-turbulence : “Feathers in flight inspire anti-turbulence technology” (RMIT University). Inspiration from feathers has “great potential for all sizes of aircraft and could not only reduce the effects of turbulence on passengers but also reduce loads on plane wings, leading to lower fatigue and hence longer life.”Ant electronics : “Ant behavior might shed insight on problems facing electronics design” (PhysOrg). “The swarm-intelligent framework at the heart of [Michael] Hsiao’s approach [at Virginia Tech] is based on long-term research he has conducted using algorithms that simulate the methods used by ant colonies to find the most efficient route to food sources.”Beetle wing deployable structures : “Asymmetric hindwing foldings in rove beetles” (PNAS). “Rove beetles are known to fold their wings in the most complicated and sophisticated ways that have right–left asymmetric patterns. This asymmetric folding can confer both high deployment capability and high storage efficiency, and therefore has a great deal of potential for engineering applications.” Examples include “design possibilities for all deployable structures, from space structures to articles of daily use.”Beetle anti-counterfeit ink : “Longhorn beetle inspires ink to fight counterfeiting” (PhysOrg). The longhorn beetle can shift its color from red to black and back again. Inspired by this feat, Chinese researchers have designed “responsive colloidal photonic crystals” into ink that would make money difficult to counterfeit. And it’s not just for cash: designing controllable, responsive optical properties “is of great promise for developing advanced responsive … devices such as anticounterfeiting devices, multifunctional microchips, sensor arrays, or dynamic displays.”DNA cancer-fighting package : “Bio-inspired ‘nano-cocoons’ offer targeted drug delivery against cancer cells” (PhysOrg). At U of North Carolina at Chapel Hill, “Biomedical engineering researchers have developed a drug delivery system consisting of nanoscale “cocoons” made of DNA that target cancer cells and trick the cells into absorbing the cocoon before unleashing anticancer drugs.”Parakeet drones : “Bird brains may help drones fly and avoid crashing” (PhysOrg). Starlings fly in formation, but so do budgerigars or budgies (what American consumers call parakeets). “Birds have a remarkable ability to fly through complex environments with incredible speed, rarely colliding.” That inspired tests with budgies in tunnels to see how they avoided objects. The study “has the potential for helping the design of navigation and guidance systems for autonomous drones – especially when you have a flock of delivery drones” like those Google and FedEx want to use to deliver packages to customers. The article includes the famous video clip of a peregrine falcon at high speed and a goshawk navigating rapidly and flawlessly between trees in the forest.Protein carbon capture : “Inspired by nature, scientists design protein-esque molecules to lock up carbon dioxide” (PhysOrg). Seashells capture dissolved carbon dioxide in the water through the use of specialized proteins. Engineers at Pacific Northwest National Laboratory are using rational design to make “peptoids” (highly stable protein-like molecules), then “are studying the ability of peptoids to assemble into porous materials and mimic protein membranes in filtering out desired targets, such as carbon dioxide.”A-peeling food storage : “The Elixir of Life for Produce: Reducing waste by extending the life of produce” (National Geographic). The Apeel Corporation is taking cues from the peelings of fruits and vegetables that reduce spoilage. Keeping produce fresh twice as long would appeal to anyone with food in the frig. With their new products Apeel, Edipeel and Florapeel coming to market, “Who says bioengineering isn’t romantic?” the article quips.Dog bomb sniffers : “Billions Have Been Spent on Technology to Find IEDs, but Dogs Still Do It Better” (National Geographic). Here’s a nature feat that engineers have not been able to copy yet. As you remember soldiers on Veteran’s Day, don’t forget their canine companions. “These working dogs have saved countless soldiers’ lives—and helped prevent PTSD.” (Note: PhysOrg reports that fruit flies are also good bomb sniffers.)These are things the “Bioneers” have a jump on (see 10/29/05). You’re missing out because you didn’t think of it first. But don’t be dismayed; if there is truly an “infinite reservoir of inspiration” in biological systems, you can start looking around your yard right now for a creature to learn about. Then find out how it solved a real world problem, figure out the principles, create an invention, obtain a patent, start a company, and make a lot of money – while helping humanity. Did Darwinism ever give you that kind of inspiration? (Answer: no. It inspired things like genocide and world wars.) Design science is on a roll, improving the world. Nowhere is the contrast between the good fruit of good science and the evil fruit of bad science more apparent than in the contrast between evolution and biomimetics. “You will know them by their fruits” Francis Bacon said. Guess where he got that proverb. (Visited 35 times, 1 visits today)FacebookTwitterPinterestSave分享0

Cabinet has agreed to the establishment of a National Craft Council, says Minister of Education, Youth and Information, Senator the Hon. Ruel Reid.Addressing a recent post-Cabinet press briefing at Jamaica House, the Minister said this follows a submission from the Ministry of Industry, Commerce, Agriculture and Fisheries (MICAF) and a concept paper presented by the Ministry of Tourism to the Cabinet.He explained that the submission by MICAF highlighted the rationale for the policy and noted that the vision is for a viable, sustainable, diversified and internationally competitive industry showcasing authentic Jamaican products that have the capacity to sustain livelihood and leverage inherent creativity in cultural expression among the Jamaican people.Senator Reid said the cross-cutting nature of the craft industry was highlighted by the strategic objectives of the policy. This includes the establishment of a Craft Council and the establishment of artisan villages.“Given the nature of the industry, an integrated multisectoral approach across ministries and agencies was deemed necessary,” he explained.
