Competing for a mate can shorten lifespan

first_img“Love stinks!” the J. Geils band told the world in 1980, and while you can certainly argue whether or not this tender and ineffable spirit of affection has a downside, working hard to find it does.  It may even shorten your life.A new study by Harvard researchers shows that ratios between males and females affect human longevity.  Men who reach sexual maturity in a context in which they far outnumber women live, on average, three months less than men whose competition for a mate isn’t as stiff.  The steeper the gender ratio (also known as the operational sex ratio), the sharper the decline in lifespan.“At first blush, a quarter of a year may not seem like much, but it is comparable to the effects of, say, taking a daily aspirin, or engaging in moderate exercise,” says Nicholas Christakis, senior author on the study and professor of medicine and medical sociology at Harvard Medical School as well as professor of sociology at Harvard University’s Faculty of Arts and Sciences.  “A  65-year-old man is typically expected to live another 15.4 years.  Removing three months from this block of time is significant.”These results are published in the August issue of the journal Demography.An association between gender ratios and longevity had been established through studies of animals before, but never in humans.  To search for a link in people, Christakis collaborated with researchers Lei Jin, from the Chinese University of Hong Kong, Felix Elwert of the University of Wisconsin, and Jeremy Freese of Northwestern University.The researchers looked at two distinct datasets.First, they examined information from the Wisconsin Longitudinal Study, a long-term project involving individuals who graduated from Wisconsin high schools in 1957.  The researchers calculated the gender ratios of each high-school graduating class, then ascertained how long the graduates went on to live.  After adjusting for a multitude of factors, they discovered that 50 years later men from classes with an excess of boys did not live as long as men whose classes were gender-balanced.  By one measurement, mortality for a 65-year-old who had experienced a steeper sex ratio decades earlier as a teenager was 1.6 percent higher than one who hadn’t faced such] stiff competition for female attention.Next, the research team compared Medicare claims data with census data for a complete national sample of more than 7 million men throughout the United States and arrived at similar results (for technical reasons, the study was unable to evaluate results for women who outnumbered men at sexual maturity).Much attention has been paid to the deleterious social effects of gender imbalances in countries such as China and India, where selective abortion, internal migration and other factors have in some areas resulted in men outnumbering women by up to twenty percent.  Such an environment, already associated with a marked increase in violence and human trafficking, appears to shorten life as well.The researchers have not investigated mechanisms that might account for this phenomenon, but Christakis suspects that it arises from a combination of social and biological factors. After all, finding a mate can be stressful, and stress as a contributor to health disorders has been well documented.Says Christakis, “We literally come to embody the social world around us, and what could be more social than the dynamics of sexual competition?”The research was funded by the National Institutes of Health and the Robert Wood Johnson Foundation.last_img read more

Onward and upward, robots

first_imgEDGE OF DISCOVERYFirst in a series of articles on cutting-edge research at Harvard.On a visit to one Harvard robotics lab, the sewing machines stand out, while the head of another explains how and why lab members are studying termites in Namibia.Welcome to the new age of machines, in which scientists with seemingly disparate talents are using cutting-edge materials, cheap sensors, 3-D printing, and powerful computers to accelerate advances in robotics.Prior innovations transformed the factory and warehouse, but those robots work best in controlled environments, usually out of public view. For researchers at Harvard and elsewhere, one new target is Main Street. “We were promised these things by sci-fi for 50 years,” said Robert Wood, Charles River Professor of Engineering and Applied Sciences. “So where are the robots?”The next generation will venture widely into the real world, trekking through forests and fields, driving around town, and covering chores. Major retailers such as Amazon are frank about their desire to deliver packages with drones, automakers want your car to steer itself, and for those who can’t find the time to vacuum the living room rug, there’s a robot for that.But tomorrow’s machines won’t just drop you off, deliver your packages, and clean your house. They will also search for disaster victims and help farm food, experts say. They’ll fight wars, brace limbs, and heal hearts.“Certainly, the technology is now there, and there’ve been some developments over the last decade that allow us to build robots good enough to deal with the real world,” said Robert Howe, the Abbott and James Lawrence Professor of Engineering.,“We build the kinds of robots that people haven’t imagined yet. Little bees that fly, thousands of robots you buy, robots that build by climbing over things, robots that you wear.” – Radhika Nagpal, pictured above,Momentum buildersHarvard’s recent efforts in robotics have enlivened a historically quiet scene. George Whitesides, the Woodford L. and Ann A. Flowers University Professor, noted that his own soft-robot breakthroughs have as much to do with Harvard’s strength in soft-matter physics and with colleagues’ microfluidics work as with robotics.Some of the earliest work on soft robots was done by Japanese researchers in the 1990s. More recently, innovations by Whitesides, Wood, and colleagues like Conor Walsh have advanced the field, paving the way for machines whose design and characteristics, rather than hard gears and levers, regulate movement.“We replace controls by the properties of materials,” Whitesides said, holding up a starfish-shaped rubber gripper that clenches when air is pumped into its arms. “These things tend to curl from the tip — that’s a controllable thing. It would be essentially impossible to replicate without all kinds of things in hard robots.”The work has led to robots that can function despite being run over by a car, that creep and crawl instead of rolling or marching. It has led to research on new manufacturing techniques, such as 3-D printing advances in the lab of Jennifer Lewis, Hansjörg Wyss Professor of Biologically Inspired Engineering. It has also led to a collaboration with National Geographic on underwater graspers capable of collecting samples of delicate coral, and to the development of a company, Soft Robotics, to commercialize flexible grippers that can handle an array of products — on a farm, in a warehouse, or on an assembly line.,“The transition to market has been an interesting one,” said Whitesides. “What’s turned out to be the initial application is for things I didn’t know existed as problems. … It made it from the lab to commercial [applications] faster than anything I’ve ever been involved in.”Companies like Soft Robotics provide a relatively straightforward measure of robotics progress at Harvard, according to Sam Liss, executive director of strategic partnerships for Harvard’s Office of Technology Development.“The level of startup formation is remarkable,” he said. “Within just the last few years, we’ve seen the launch of Soft Robotics, RightHand Robotics, and Root Robotics, with more to follow. This is a sea change at Harvard. It speaks to not only the significance of the research, but also to our faculty’s focus on translating this research into products that will have impact.”Growth in robotics at Harvard has been driven by the Paulson School of Engineering and Applied Sciences, and the Wyss Institute for Biologically Inspired Engineering. Researchers say deeper investment in robot-building tools and facilities has made an enormous difference to faculty, students, and fellows.“Especially for the things I do, it’s really important to have those tools accessible for students and postdocs,” Wood said. “SEAS and the Wyss Institute have done a very good job of investing in some of those areas. We don’t really lack anything in that regard.”,Team efforts Harvard has a small core of less than a dozen robotics specialists who collaborate regularly and rely heavily on one another’s expertise. The focus is on land, sea, and air machines that can work closely with humans, often in medical settings, and which think and behave in ways that reflect the innovative drive of their developers.“We build the kinds of robots that people haven’t imagined yet,” said Radhika Nagpal, the Fred Kavli Professor of Computer Science. “Little bees that fly, thousands of robots you buy, robots that build by climbing over things, robots that you wear. Our strength in some ways is the wild and crazy robots. Robots that are more like animals than they are wheeled cars.”One example is the RoboBee. Developed by Wood and controlled by Nagpal’s software, the insect-sized flying robot has wide potential as a surveying tool, with the ability to collect images and data from natural disasters, crop-disease outbreaks, even war zones. Small enough that mechanical levers, gears, and other off-the-shelf components were impractical, the machine demanded advances in areas beyond robotic design.“With RoboBees, no component was off the shelf,” said Wood. “We had to invent everything from the ground up: new manufacturing methods, new actuation, sensing, computing architecture, new energy storage — then [with] Radhika, new algorithms to control behavior. A lot of the platforms we work on don’t exist and we have to develop them from scratch. We really like those, not just because of the cool factor but because of the tech fallout along the way.”Sensors and actuators light enough to fly on a robotic insect, for example, might be useful in biomedical devices in which size is crucial, like those used in minimally invasive procedures, said Wood.“We’re taking all these technologies developed from RoboBees, blending them with soft robotics to make new tools for endoscopy and come up with techniques for procedures that are otherwise quite hard to do,” he said.A central attraction of medical robotics is the chance to make a positive impact in people’s lives, said Walsh, the John J. Loeb Associate Professor of Engineering and Applied Sciences, whose lab-sewn soft-robotic exosuit may one day help stroke patients walk with greater ease. With Harvard Medical School and its 16 affiliated hospitals and research institutions nearby, robotics faculty are well-positioned to determine patient needs that robots might fill, and to collaborate with physicians on setting solutions in motion.For example, in work backed by the National Institutes of Health, Howe and Pierre Dupont, chief of pediatric cardiac-bioengineering at Harvard-affiliated Boston Children’s Hospital, have collaborated for years on robotic technology for beating-heart surgery. They are currently working on complementary approaches for controlling how robotic catheters compensate for the motion of a beating heart. Success would allow patients to skip open-heart surgery in favor of a minimally invasive procedure.“It would be so much better for the patient — less trauma, less risk,” said Dupont. “We’re trying to develop technology clinicians haven’t dreamed of yet.”,“I see opportunities for types of things we’re doing to actually make a difference in people’s lives.” — Conor Walsh, above,Meanwhile, Walsh’s exosuit technology has been licensed to ReWalk Robotics, whose plan to put a product in clinical trials this year is a first step in a strategy to bring the machine from concept to market in less than five years.“I see opportunities for types of things we’re doing to actually make a difference in people’s lives,” Walsh said.The medical applications of Walsh’s work — which includes devices to counter heart failure, improve arm function for patients with spinal-cord injury, and boost post-stroke mobility — owe to early and ongoing support from the Defense Advanced Research Projects Agency (DARPA), whose focus is on an exosuit that might ease the burden of 100-pound troop packs.Soft exosuits combine properties of functional apparel with precise placement of cables and motors to strategically assist movement.“The concept of going with a soft system is you can make the system very lightweight, very nonrestrictive, that has a minimal impact on the biomechanics of a person while they walk and is able to deliver a boost in addition to what the wearer’s muscles are normally doing,” Walsh said. “The question then is … can we have a positive effect on a person’s mobility?”So far, in tests on treadmills and on miles-long military hikes, that effect has been measured at 15 percent. In addition, Walsh’s team has demonstrated in experiments with stroke patients that the exosuit can help users clear the ground and push off at the ankle, reducing functional asymmetry between limbs and increasing walking efficiency. Key challenges going forward will include minimizing weight while maximizing assistance and syncing the suit with natural movements.“Is this in synergy with this person?” Walsh said. “Because if you get the timing wrong, our studies have shown you don’t get anywhere near the benefit you can get, but if you get it just right you can really make a big difference to a person.”,Behavior issues  As important as how a machine moves is how it thinks, a reality that Harvard researchers themselves are thinking hard about. Scott Kuindersma, an assistant professor of engineering and computer science and director of the Harvard Agile Robotics Lab, has his sights set on ramping up control systems so that robots reach their full potential.“In my opinion, physically capable robots are already here,” said Kuindersma. “But those robots struggle to perform at their dynamic limit and lack robustness in realistic environments. That’s primarily a computational problem.”A recent arrival at Kuindersma’s lab is Cassie, a two-legged walking robot that looks something like an ostrich. Designed by Agility Robotics, Cassie is an example of advanced hardware that Kuindersma thinks can perform better.“[Cassie] is using a controller the company has developed,” Kuindersma said. “We will promptly delete this. Our goal is to develop algorithms that push locomotion performance beyond state-of-the-art, using this as an experimental platform. A major milestone for us would be to demonstrate high-speed locomotion outdoors, using visual sensor feedback at high rates to plan dynamic walking.“Think about a mountain goat,” he said. “They can scurry up a cliff face, making fast decisions on where to place their feet on very geometrically complex terrain. We’re interested in creating algorithms that can achieve that kind of performance with robots.”While Kuindersma is exploring how to better control complex individual actions, Nagpal is investigating the opposite approach: how to drive complex behavior in groups of simple individuals.“My lab has always had this theme of complexity through simplicity,” Nagpal said. “No matter what kind of agent — ant, human being, or robot — there’s always a limit to what an individual can do. We transcend that by having groups. … Animals that have evolved to work in groups really take advantage of these things.”,“No matter what kind of agent — ant, human being, or robot — there’s always a limit to what an individual can do. We transcend that by having groups. … Animals that have evolved to work in groups really take advantage of these things.” — Radhika Nagpal “A major goal of the course is getting students to think in a different way,” Hoberman said. “You might be fooled, because these devices are paper and plastic, that there’s not a lot of engineering rigor going into it. Using rapid prototyping technologies and off-the-shelf electronics, our students can make a piece of paper walk across the room and adjust its path while sensing its surroundings. The moment of truth is when they turn their device on and it takes on animate life — it’s such a great experience for young designers.”Students also get hands-on learning experiences outside the classroom. Members of the Harvard Undergraduate Robotics Club last year tackled a series of design challenges, including building an autonomous maze-solving robot, an unmanned aerial robot, and a wheeled robot that uses feedback controls to maintain balance.Members say that though each individual brings particular expertise to the club — computer science, mechanical engineering, electrical engineering — robotics is such an interdisciplinary pursuit that almost everyone ventures beyond his or her expertise.Membership in the club “had a huge impact on what I think about doing,” said Shaan Erickson ’17, who wants to marry his passions for cars and robotics in the auto industry. “It opened my eyes to an entirely different field. … I look forward to adding my own contribution to it.”Funding for the research described in this article comes in part from the Wyss Institute for Biologically Inspired Engineering and from federal agencies such as the Department of Energy, the National Science Foundation, and the Defense Advanced Research Projects Agency. Nagpal has found models in termites in Namibia and army ants in Panama, social insects that manage challenging tasks without central coordination.“There are examples in nature where the coordination required is very small, so we’re using that,” Nagpal said. “That might make it possible to have many cooperating parts. The parts don’t have to be complicated, and the coordination doesn’t have to be complicated, but you can still achieve complex goals.”Among the machines Nagpal has developed is the diminutive kilobot, programmed to behave according to simple guidelines, such as the position and behavior of neighbors. Kilobot swarms can perform complex tasks — in one demonstration they formed themselves into a starfish shape — that are not dependent on a sophisticated computer brain or a system of leaders and followers. Her group has also developed termite-inspired robots that work together on user-specified block structures.“We can produce rules that will cause them to always build the correct structure,” Nagpal said. “And it doesn’t matter if they’re 10 or five or 50, and it doesn’t matter that they don’t know where the other ones are, and it doesn’t matter what order they’re in.”Nagpal sees potential applications in disaster response, exploration, and with environmental sensors. Robots following simple rules could create walls of sandbags, while the inexpensive schools of robotic fish being developed in her lab could someday probe the ocean floor, supplementing or replacing the deployment of costly submersibles that can explore only one place at a time.The development of the kilobot is an outgrowth of a rapid advancement of technology that has not only increased the sophistication of cutting-edge systems, but also dramatically lowered the price of off-the-shelf components, Nagpal noted. “I originally thought I would never have hardware,” she said. “But the reason I thought that was a robot cost $100,000. [Today] I can build novel robots for a couple of hundred dollars. That’s a routine thing in my lab. I have a thousand robots, at $20 [each].”Nagpal has licensed kilobot technology to K-Team, a manufacturer of small mobile robots. Today, 10 other labs around the world own kilobots, and two have 1,000-kilobot swarms.“It’s super amazing, because all these things people are imagining doing with the kilobot system, I would never have thought of. Now it’s a vibrant research area,” Nagpal said.,Tomorrow’s innovators While faculty members are developing the next wave of robots, students are gaining the knowledge and experience to build the machines of the second half of the 21st century. Budding innovators learn as interns, through extracurriculars such as the Harvard Undergraduate Robotics Club, and in the classroom. A search of Harvard’s course catalog for “robot” returns options in microrobotics, artificial intelligence, control theory, and more.“Informal Robotics: New Paradigms for Design and Construction,” taught by Chuck Hoberman, a lecturer in architecture at Harvard’s Graduate School of Design, illustrates just how far the field has come. Instead of building complex machines in a high-tech lab, students merge everyday materials with inexpensive computer parts to build robots that can sense and respond to surrounding stimuli.center_img The Daily Gazette Sign up for daily emails to get the latest Harvard news.last_img read more

Heirloom tomatoes

first_imgBy William Terry KelleyUniversity ofGeorgiaMost folks know that a store-bought tomato just doesn’t taste asgood as one you pick from your garden. That’s why tomatoes arethe most widely grown U.S. garden crop. But “new and improved”varieties don’t always impress the tomato connoisseur.The term “heirloom tomatoes” was coined a few years back. It’sused to describe the old-fashioned varieties many gardenersbelieve have the best flavor. So why are the newer varieties”improved.” Well, they resist some diseases that heirlooms don’t.Nevertheless, heirlooms are becoming popular. From red to yellowto chocolate to green, these tomatoes come in a variety ofvarieties. Some date back to the 1800s. Many come from Europe.Nearly all are indeterminate types that will keep growing andproducing all season and require extensive trellising.The basics of growing these varieties doesn’t differ much fromordinary tomatoes. Trellising and varieties are the only realdifferences. Plant spacing, fertility and planting dates will allbe the same as for any tomato.Heirloom samplerHere’s a sampler of some of the more popular heirloom varieties:”Brandywine” dates back to 1885. Itproduces pinkish red tomatoes from 1 to 1.5 pounds and matures in80 days.”Abraham Lincoln” matures in 77days. It’s a red variety dating to 1920, producing fruit from 6to 10 ounces.”Mortgage Lifter” got its namebecause the man who developed it supposedly produced so muchfruit that he paid off his mortgage with the profit. It has pinkfruit that can get up to 2 pounds and matures in 85 days.”German Giant” can also reach 2pounds. It’s a deep pink and matures in 77 days.If you’re looking for a tomato of a different color, you may wantto try “Cherokee Purple,” whichoriginated in Tennessee. It has rose to purple skin, matures in80 days and weighs 10 to 12 ounces.Or how about “Mr. Stripey,” which isred, orange and yellow striped? It matures in only 56 days andhas fruit only 1 inch to 1.5 inches in diameter.Other varieties include “GreenZebra,” “Old German,” “Yellow Brandywine,” “Old Brooks,” “Thessaloniki,” “Arkansas Traveler” and “Giant Belgium.” Be careful how many youplant. Many of these varieties can produce as much as 15 poundsof fruit per plant.Planting tipsAs with all tomatoes, don’t plant them until the danger of frosthas passed. Tomatoes are best transplanted into the garden, too,rather than directly seeded. Many garden centers now carry plantsof these old-time varieties.Tomatoes must be grown in full sunlight in a well-drained area.Select a site where water is available for irrigation. The soilpH should be between 6.2 and 6.8.Good transplants are stocky and 8 to 10 inches tall. Cover therootball of the plant completely. Don’t be afraid to plant itdeep enough to cover the bottom leaves.Plant tomatoes 18 to 24 inches apart in rows 5 to 6 feet apart.Heirloom tomatoes are best trellised, using an overhead wirestretched between two solid posts no farther than 20 feet apart.Then tie twine from the wire down to the plants to support themand keep them off of the ground. You will likely have to removesuckers and prune these varieties to two main stems.Use about 1.3 pounds of 10-10-10 analysis fertilizer per 100square feet. Work this into the ground before planting.Side-dress the plants with the same fertilizer rate after aboutfour weeks and then again in another four to five weeks.The quest for the most flavorful tomato has begun. Will it comefrom your garden this year?(Terry Kelley is a Cooperative Extension horticulturist withthe University of Georgia College of Agricultural andEnvironmental Sciences.)last_img read more

Chilean Submarine Completes Exercise with US Navy

first_img Chilean submarine (CS) Simpson (SS-21) departed Naval Station Mayport, Florida, to return to homeport in Talcahuano, Chile, on February 7, after taking part in the Diesel Electric Submarine Initiative (DESI), and CHILEMAR IV with the U.S. Navy. DESI is a partnership that allows the United States and other partner navies to work together to train and test underwater warfare capabilities through engagement tactics, weapon system tests and close encounter operations. This particular training evolution helps the U.S. and Chilean navies train their crews and test capabilities while helping foster bilateral cooperation and further improve joint interoperability. CHILEMAR is an annual bilateral exercise between the U.S. and Chile, which is designed to demonstrate interoperability between U.S. submarine rescue systems and Chilean submarines. The exercise also promotes greater understanding and cooperation between the U.S. and Chile. During its three-month deployment, Simpson conducted training with both surface ships and air units. Shortly after Simpson arrived in Mayport, the submarine participated in independent deployed certification exercises with various units from the USS KEARSARGE Amphibious Readiness Group. In January the crew took part in CHILEMAR IV, which focused on the notification and localization phases of a bottomed, disabled submarine. Several U.S. Atlantic Fleet air and surface units also participated in the exercise, employing side-scan sonar, an undersea unmanned vehicle, and several P-3 Orion and SH-60 aircraft. Simpson then participated in an anti-submarine warfare exercise with Helicopter Maritime Strike Weapons School, and excelled in its role in the Harry S. Truman Carrier Strike Group Composite Training Unit Exercise. Rear Admiral Joseph Tofalo, commander of Submarine Group 10 was at the closing ceremony for DESI, held aboard Naval Station Mayport, and talked about the importance of such exercises. “I was actually in the audience when former U.S. Chief of Naval Operations Admiral Gary Roughead rolled out the cooperative strategy for 21st Century Sea Power, and I’ll never forget his words where he stated, ‘you can’t surge trust.’ Rather, it takes long term relationships, built upon interactions like CHILEMAR and DESI, to foster the important bond between our great nations,” he said. Also in attendance at the closing ceremony was Chilean Vice Admiral José Romero, commander of naval operations, who talked about the importance of the U.S. and Chilean Navies continuing to work together. “Exercises such as this will only continue to improve the interoperability of our Navies, which is important for our nations,” Romero said. Commander Eduardo Torres, commanding officer of Simpson, thanked his crew and Naval Station Mayport during his speech. “To the crew of Simpson, thank you for your hard work, I would like to thank Naval Station Mayport for giving us the support we needed when we were in port,” he said. It will take the submarine a month to travel through the Atlantic Ocean, Caribbean Sea and Pacific Ocean to reach its homeport on the southern tip of South America. By Dialogo February 13, 2013 The information on the cooperation between the Army of Chile and the U. S. is excellent.last_img read more

New York jury finds man guilty of credit union robbery-murder

Another member, Joseph Doud, was shot and injured but survived.The fatal robbery case that shocked the Rochester community went cold for 13 years, but it was never forgotten.Finally, in September 2016, the FBI and federal prosecutors announced they solved the cold case with DNA samples, which matched Wilbern’s DNA. The samples were collected from an umbrella that the suspect left behind in the branch.last_img read more

Beyond Meat to launch two new versions of its meatless burger

first_imgBeyond Meat’s line-up of meat substitutes will soon include two new versions of its Beyond Burger.The new burgers are meant to offer consumers more choice and will launch nationwide early next year. Beyond said that one of the patties is its juiciest yet but has 35% less saturated fat than a burger made from a blend of beef that is 80% lean meat and 20% fat. The other burger is meant to appeal more to a health-minded consumer, with 55% less saturated fat than a typical beef burger. Beyond said that the two burgers will have B vitamins and minerals, similar to beef.- Advertisement – – Advertisement – Beyond Burger launches new meatier burger.Source: Beyond Burger As meat substitutes from Beyond and Impossible Foods have grown more popular in the last few years, their meat-free burgers have also drawn criticism for being marketed as a healthier alternative to red meat. Dietitians have said that it would be better for consumers to view plant-based burgers as an indulgence, as they would a beef burger. Shares of Beyond, which has a market value of $7.88 billion, have risen 66% so far this year. The stock is up less than 1% in premarket trading on Monday. – Advertisement –last_img read more
