Image credit: Donna Coveney. Explore further Byoungwoo Kang and Gerbrand Ceder of MIT have improved the design of a “nanoball battery,” which has a cathode that is composed of nanosized balls of lithium iron phosphate. As the battery charges, the nanoballs release lithium ions that travel across an electrolyte to the anode. As the battery discharges, the opposite occurs, and the lithium ions are reabsorbed by the nanoballs in the cathode. The key to the nanoball battery’s quick charge time is the speed at which the lithium iron phosphate nanoballs in the cathode can release and absorb lithium ions. In conventional lithium ion batteries, detaching the ions from the normal cathode takes a relatively long time. By coating each nanoball with a thin layer of lithium phosphate, Kang and Ceder showed that they could detach the lithium ions from the nanoballs even quicker than previous studies have found. To demonstrate the technology, the researchers fabricated a small battery that could be fully charged or discharged in 10 to 20 seconds, which would otherwise have taken six minutes. The scientists’ tests showed that the new material degrades less than other battery materials after repeated charges and discharges. This means that the battery could be made with less material, which could possibly lead to smaller, lighter batteries.More information: Byoungwoo Kang and Gerbrand Ceder. “Battery materials for ultrafast charging and discharging.” Nature 458, 190-193 (12 March 2009), doi:10.1038/nature07853.© 2009 PhysOrg.com New battery material could lead to rapid recharging of many devices (PhysOrg.com) — Researchers at MIT have designed a new battery that can recharge devices about 100 times faster than conventional lithium ion batteries.

Buffer gas cooling could open up the field of ultracold physics

first_img(PhysOrg.com) — “Scientists have been making Bose-Einstein Condensates [BECs] for nearly 15 years,” Charlie Doret tells PhysOrg.com. “Essentially all BEC research to date, however, begins with laser cooling. Unfortunately, laser cooling is impractical for some atoms, and it is especially difficult with molecules, limiting the scope of new research.” This document is subject to copyright.

Along with Colin Connolly and John Doyle at Harvard and Wolfgang Ketterle at MIT, Doret believes that their more widely applicable technique will enable creation of BECs with new atoms and molecules. Their work can be found in Physical Review Letters: “Buffer-Gas Cooled Bose-Einstein Condensate.” To make BECs with ultracold atoms and molecules, an initial cooling and trapping stage is needed. The atoms or molecules in question are cooled to a point where they are moving slowly enough to be trapped. Once they are trapped they can be cooled further, leading to Bose-Einstein condensation. BECs are useful in a number of experiments, and have potential practical applications due to their similarities to laser light. “Unfortunately,” Doret points out, “laser cooling just doesn’t work well for some stuff.” In laser cooling, photons are sent to bombard the atom in such a way that it eventually slows down, via a scattering process. Doret explains that this technique is similar to using golf balls to slow down a bowling ball. “It works eventually, but it takes a lot of photon scattering events to slow an atom, just as you would expect to use a great many golf balls to effectively slow a bowling ball.” Instead of using lasers to slow down an atom, Doret and his peers opted for using a buffer gas. “We have a cold gas that we can bounce off of hot atoms. Collisions with this buffer gas cools the atoms, making them easier to magnetically trap, after which they can be further cooled until they Bose-condense.” For the current experiment, the Harvard and MIT team used cooled helium gas as a buffer to cool metastable helium atoms. “We have demonstrated the process from start to finish with atoms, but we haven’t done it with molecules. But the principle should be the same, and our next attempt will probably be to attempt to use buffer-gas cooling – with a few little tweaks – to create a BEC of the NH molecule.” A general path to BEC with molecules would be a huge step forward for ultracold physics, Doret insists. “One big effect it could have is for the possibility of building a quantum computer. One way that has been suggested is to take polar molecules and trap them in an optical lattice, using the cold molecules as qubits. Due to the difficulty of laser cooling molecules, getting polar molecules into a lattice is a challenging but important step. Buffer-gas cooling could work, though.” In the end, Doret believes that buffer-gas cooling could provide the means to experiment further with BECs and other subjects of interest. “Buffer-gas cooling allows us to use atoms and molecules not accessible in the past. There are new applications to pursue, and more tools that can be brought into play. This could open up the entire field of ultracold physics.” More information: Doret, et. al. “Buffer-Gas Cooled Bose-Einstein Condensate,” Physical Review Letters (2009).

Citation: Seabird’s morphing wings inspire design for robots that can both fly and swim (2010, November 19) retrieved 18 August 2019 from https://phys.org/news/2010-11-seabird-morphing-wings-robots.html (PhysOrg.com) — There are robots that can fly, and there are robots that can swim, but so far a robot that can both fly and swim does not exist. With the goal to design an aerial/aquatic robotic vehicle, a team of researchers is investigating how nature achieves both aerial and aquatic motion in a single entity, particularly in a seabird called the common guillemot. They plan to use their calculations, models, and simulations to design a robotic vehicle with a morphing wing similar to the one used by the seabird. Copyright 2010 PhysOrg.com.All rights reserved. This material may not be published, broadcast, rewritten or redistributed in whole or part without the express written permission of PhysOrg.com. Explore further A robotic vehicle with the ability to fly and swim could have a variety of applications. For example, the vehicle could be used to inspect underwater oil pipes while flying to and from remote oil rigs. It could also be used for aerial and aquatic surveillance for counter-terrorism purposes. Variations in the missions could require very different operating speeds in each medium. The numerical model developed by the researchers takes these issues into consideration and can provide mission-specific optimal values to use in future concept vehicle designs. Currently, the researchers are developing an experimental platform from which they can investigate various parameters associated with flapping propulsion during aquatic locomotion.As Lock noted, there are still several challenges that need to be addressed, starting with the need to better understand the performance compromise between operations in the air and water due to the fact that robots of this type have not yet reached a level of maturity within the research community. “The second biggest challenge that we face is one that everybody within the robotics community has to deal with, and that is the problem of a suitable power source,” he said. “There is of course a finite payload which any robotic vehicle can carry, of which the power source invariably contributes a significant proportion of the overall mass. Implementing a power source that is light enough to allow aerial operations but provides sufficient power to enable the use of the locomotion mechanisms for any feasible length of time is a huge problem that we face. Luckily this is a common problem faced by many robots whereby the ultimate aim is for the untethered operations and as such many research groups are striving towards new power sources with greater power-to-weight ratios and lifespans. Although not currently available, we believe that in time a suitable power source will be developed that allows aerial/aquatic vehicles to be developed.“Finally, the third challenge we face comes from developing a vehicle of this scale capable of aerial operations utilizing beating wing flight. Very few mature examples exist that achieve this mode of locomotion through a flapping locomotion strategy, and they are not attempting operations in water as well. Solutions to this problem do exist, such as the inclusion of an additional propulsion source for use whilst in air such as a propeller, but this then moves away from the biological example from which the work drew inspiration. However, we are not ruling this out as a stepping stone whilst addressing other elements of the complex task that we face.”center_img The common guillemot flies with straight wings and swims with bent wings, which reduces profile drag by up to 50%. This strategy is providing inspiration for the design of aerial/aquatic robotic vehicles. Image credit: Lock, et al. Adapted from unpublished BBC footage.)

Biomim. 5 (2010) 046001 (15pp). DOI:10.1088/1748-3182/5/4/046001 Researchers Richard Lock, who is working under the supervision of Dr. Ravi Vaidyanathan at the Bristol Robotics Laboratory, University of Bristol, and coauthors, have published their investigation of the common guillemot’s locomotive abilities in a recent issue of Bioinspiration & Biomimetics. “The capacity to mathematically model the morphological shifts the bird makes from aerial to aquatic media is our first step in being able to reproduce the process,” Lock told PhysOrg.com. “Understanding locomotion in a single medium is already a complex problem to solve; therefore, attempting to further our understanding of systems with a multi-modal capability, i.e., operations in two different media, provides many challenges. Our work focuses on trying to understand this balance between the different media, focusing on how different mission requirements present different compromises in performance.”As the researchers explained, a variety of birds and insects are capable of locomotion in both air and water. However, these animals are confronted with numerous physiological challenges, due primarily to the fact that water is some 800 times denser than air. The animals’ locomotive strategies that solve this problem can generally be divided into two categories: two different mechanisms for the two different media, or a single mechanism adapted for both media. The common guillemot falls into the second category, as it flaps its wings for locomotion in both media. However, the bird modifies its wing shape when swimming by folding part of its wing. This simple change results in a reduction of surface area, which, as the researchers calculated, reduces profile drag by as much as 50% and significantly reduces the overall power requirements. This ability enables the common guillemot to nest on land along the coast, fly up to 30 km out to sea, dive underwater, and flap its wings to swim and hunt for marine food. After developing a model of the common guillemot’s wing size, shape, and flapping behavior, the researchers validated the model with simulations. Their goal was to find the values of key variables that achieve the highest performance (i.e., the lowest energy requirements) for a robotic vehicle that could fly with a range of 2 km at a velocity of 20 m/s and swim with a range of 500 m at a velocity of 1.5 m/s. These values are similar to that of the typical feeding habits of the common guillemot. The model’s suggested values for key geometric and kinematic parameters were in close agreement to those exhibited by the guillemot, providing the researchers with preliminary validation of their numerical model. The model can also be used for additional missions based on projected uses of the concept vehicle.last_img read more

Image credit: NPG, doi:10.1038/ncomms1262 Researchers point out that these natural impulses in the monkeys and their desire to eat the raisins interfered with their judgment in the initial experiment. Similar to young children and the reverse reward paradigm, these monkeys were not able to see past their desire to eat the raisins.In the reverse reward paradigm, young children are presented with two piles of candies of different sizes. The children will always point to the larger pile and then this pile is given to another child. Children have difficulty understanding that by choosing the smaller pile, they will receive the larger pile. However, if this test is repeated with non-edible objects, the children are able to understand and perform the experiment correctly.Researchers in this study point to the same interference in judgment by the monkeys when presented with food. Their desire to eat the food gets in the way of the task at hand. These researchers believe that previous studies performed on other primates using food as a test symbol may have impaired results and therefore underestimated the primate’s numeracy abilities. © 2010 PhysOrg.com Macaca fascicularis, long-tailed macaque.

The idea being that the monkeys would choose the plate with the larger number of raisins. In this first experiment, the monkeys were then allowed to eat the raisins on the plate they choose. In this experiment, researchers found that the monkeys had a tendency to get this wrong and chose the plate with the smaller amount of raisins.In the second experiment, the researchers decided to replace the raisins with non-edible objects, in this case pebbles. When presented these plates with pebbles, the monkeys did much better.The third experiment returned to the plates with raisins, but instead of being rewarded with the raisins on the plate, the monkeys were rewarded with raisins hidden underneath. This experiment showed the same results as the pebbles. (PhysOrg.com) — In a recent study published in Nature Communications, it appears that Old World monkeys have the ability to count better than was originally thought. The research also shows that when presented with counting tasks, these long-tailed macaques are very similar to children in suppressing their impulses.last_img read more

Ten centimeters long, the 15-gram CLASH moves up cloth fast in an insect-like scurrying motion. The motor in CLASH powers the legs and drives its swift gait frequency. According to the Biomimetic Millisystems Lab site, the robotic device “is capable of climbing a loose cloth surface at 15 cm per second using a simple passive claw mechanism and a coupled in-plane leg drive system.”Each leg is connected to the single motor through a series of linkages. A point of design interest about CLASH is centered on the gripping and climbing technique the team devised, where tiny spikes on the robit’s feet grip into loose fabric and let the bot climb. The electronics and battery are configured into the tail of the robot, which adds balance. The CLASH newcomer belongs to the lab’s family of “Ambulating Robots.” They make a case for the value of legged systems rather than wheeled systems. Key performance advantages in legged systems is because the feet are not continually in contact with the ground, which makes legged robots better able to cross challenging terrain, they note. Perhaps the most interesting advantage, say the researchers, is in dynamic behavior seen in nature. “Many legged animals exhibit dynamically, self-stabilizing behavior. That is, the passive mechanical properties of the systems are tuned to naturally reject disturbances which might otherwise cause unstable behavior in the system.”Last month the Berkeley team of P. Birkmeyer, A. G. Gillies, and R. S. Fearing presented “CLASH: Climbing Vertical Loose Cloth” at IROS 2011 (International Conference on Intelligent Robots and Systems) in San Francisco.The lab’s work on CLASH is not done yet. According to a report in IEEE Spectrum, they want to get CLASH to crawl horizontally, and they want CLASH to turn.

Credit: DrMikeBaxter/Wikipedia In recent years, scientists have discovered that early humans moving out of Africa encountered Neanderthals living in parts of what is now Europe and Eastern Asia. In comparing Neanderthal DNA with modern humans, researchers have found that there was a least one pairing that led to offspring, which is reflected in the DNA of humans—approximately 2 percent of the DNA in non-African humans today is Neanderthal. In this new effort, the researchers have found evidence that suggests there was more than one such encounter. Their findings make logical sense, considering that anatomically modern humans and Neanderthals coexisted for approximately 30,000 years. Recent research by other groups had suggested that multiple offspring-producing unions had occurred—some people in East Asia, for example, were found to have up to 20 percent more Neanderthal DNA than people of strictly European descent. In this new effort, the researchers took a more stringent look to find out once and for all if there had been multiple pairings or just one. They pulled and analyzed data from the 1000 Genomes Project, measuring the amount of Neanderthal DNA in genetic material from volunteers. The first step was separating the data between people of European and Asian ancestry. Doing so suggested that both groups had evidence of early multiple mating events. The researchers then studied the rates of the two groups by creating simulations showing outcomes of differing numbers of mating events between the two groups. Data from the simulations was then fed into a machine-learning algorithm that showed DNA percentage patterns based on the number of cross-breeding events that had occurred.The researchers concluded that the most likely scenario was that there were multiple instances of cross-breeding between early humans in both East Asia and Europe with Neanderthals. © 2018 Science X Networklast_img read more

Three researchbased lessons to improve your mentoring

On

first_imgSome scientists are truly extraordinary mentors. Take, for example, professor Charlotta Turner, a chemist at Lund University in Sweden, who in 2014 received a text from her Ph.D. student telling her that he might not finish his thesis in time. When she learned that her student, Firas Jumaah, was in fact hiding with his family in an Iraqi factory as armed members of the Islamic State group roamed the streets outside, she leapt into action and worked with the university’s security chair to arrange a daring rescue operation. But for every heroic mentor, there are just as many horror stories about bad ones. Unfortunately, most mentors don’t always have the tools or training to provide the proper support to their mentees (and, unfortunately, some just don’t care). Becoming a better mentor should be a central concern for new faculty members starting their own labs, but also for graduate students and postdocs mentoring research assistants—and even for more senior faculty members who are continually striving to improve their mentoring. Our capacity for growth as mentors is a lifelong journey. Read the whole story: Sciencecenter_img One way to address this issue is by learning the science behind great mentoring, as Jay and colleagues discussed on a panel recently. Instead of relying solely on personal anecdotes or their own gut intuitions, the panelists described theories and research on how to manage the most important relationship in science: the one between a mentor and mentee.

first_imgA newly created antibody could treat the decline in muscle mass and power associated with ageing, show results of a phase-two trial by an international research team.The myostatin antibody treatment improved muscle power in the elderly, as indicated by improvements in the ability to climb stairs, walk briskly and rise repetitively from a chair, the findings showed.“Myostatin is a natural protein produced within the body that inhibits muscle growth,” said one of the researchers Stuart Warden from Indiana University-Purdue University Indianapolis, US. “It has been hypothesised for some time that inhibition of myostatin may allow muscle to grow, resulting in improved muscle mass and physical performance. The current study confirms these beliefs,” Warden said. In the study, injections of a myostatin antibody, made by US-based Eli Lilly and Co, over a 24-week period resulted in an increase in lean (muscle) mass and improved performance on tasks requiring muscle power in patients older than 75 with low muscle strength, low muscle performance and a history of falling. “This is the first study to show that myostatin antibody treatment improves performance on activities requiring muscle power,” Warden said. “Muscle power’ refers to the ability to generate muscle force quickly. During ageing, it is lost more rapidly than muscle strength, contributing to disability, falls, reduced quality of life and, in some instances, death,” Warden explained.He said “the current study provides proof-of-concept evidence to proceed to the larger studies that are required to demonstrate whether myostatin antibody treatment improves quality of life and reduces falls and their consequences during ageing”.  “This is an important and exciting first step,” Warden noted in an official statement.last_img read more

This is when people get married, settle down and participate in parenthood. “The communication patterns of women would suggest their pivotal roles as parents and grandparents,” Bhattacharya noted.last_img read more

Colins Herd Hierarchy through NFL Week 3

Colins Herd Hierarchy through NFL Week 3

On

first_img8. Green Bay Packers – The Packers beat the Bengals, but they lack offensive balance, don’t have a running back, and don’t match up with the best teams in the league defensively. That being said,, Aaron Rodgers is going to carry them to a lot of wins like he did last week.He’s thrown for 300+ yards in a career-best 5 straight games, is the only QB in the NFL this season with three 300-yd passing games on the season, and Green Bay’s 6 receivers with over 100 yards is the best in the NFL. The bad news is that Rodgers has been sacked a league high 13 times and has been hit 23 times (3rd most in the NFL). They’ll need Rodgers upright if they plan on making a playoff run. 3. Denver Broncos – Even though they lost on the road to the Bills, Colin puts Denver at 3 because he believes in their dominant defense. The Broncos rank 1st in the NFL in rush defense (59.7 ypg), 4th in total defense (263.0 ypg), are tied for 3rd in 3rd down defense (28.6% conversion rate), and have allowed just one 5-minute drive all year.Offensively, quarterback Trevor Siemian has been better than Colin expected, and they lead the NFL in 3rd-down percentage (52.3%), rank 3rd in rush offense (143.0 ypg), and have 8 touchdowns in 12 red zone drives. 9. L.A. Rams – No NFL team looks more improved than the Rams under rookie head coach Sean McVay. And no individual player has more drastically changed their perception than second year quarterback Jared Goff, who is 3rd in passer rating (118.2), 3rd in comp percentage (70.4%), 1st in pass yards per attempt (10.1) and 8th in passing yards per game (272.3). Todd Gurley has been a beast, and is tied for 1st in touchdowns (6), and 2nd in the league in yards from scrimmage (381).L.A. has also been strong on defense. Their 10 sacks is 2nd in the NFC, and 20 tackles for loss is 3rd in the NFL. Colin predicted the Rams would be one of the most improved teams in the league before the season, and so far, he’s right. Advertisement Kansas City Chiefs – The 3-0 Chiefs grab the top spot for the second week in a row because they have the best overall roster in the league and do everything well. They rank 1st in rushing offense (162.0 ypg), 1st in yards per play (7.1), 3rd in scoring (31.0 ppg).Superstar rookie Kareem Hunt leads NFL in rushing (401) and tied for 1st in touchdowns (6), and Alex Smith leads NFL in passer rating (132.7), is tied for 2nd with 7 pass touchdowns, and is completing 77.4% of his passes. And Reid has the Chiefs rolling. They stay on top of the Hierarchy through Week 3. 7. Atlanta Falcons –  The Falcons are one of two undefeated teams left (Chiefs), and are the first team since the 2006 Seahawks to start 3-0 after a Super Bowl loss. They’ve been dominant offensively, ranking 2nd in yards per play (6.5), 4th in total offense (388.0 ypg), and 5th in scoring (29.0 ppg). Defensively, their tied for 3rd in the NFC with 9 sacks. Colin likes the Falcons, he just doesn’t love them as much as some. Offensively, Antonio Brown leads NFL in receptions (26) and receiving yards (354), and on defense, they’re allowing the 2nd fewest yards per play (4.23), tied for 2nd in sacks (11), and 2nd in pass defense (136.7 net ypg).center_img 5. Tennessee Titans –  The Titans just physically manhandled the Seahawks and have looked dominant offensively. They’re 2nd in the NFL in rushing yards per game (156.3 ypg), 5th in total offense (386.7 net ypg), 6th in points per game (28.7) and only have one giveaway on the year.Marcus Mariota has only been sacked twice on the year behind one of the best o-lines in the NFL, and that’s after facing Seattle’s defense. In a passing league, the Titans are a contrarian power team, and it’s working. Every week during the NFL season, Colin puts out his Herd Hierarchy NFL power rankings, and he’s made some adjustments to his Top 10 after Week 3.Dallas climbs back up the rankings after responding to their Week 2 bomb in Denver; Pittsburgh is hanging on for dear life, and the Ravens and Raiders drop out.Here are his Top 10 teams after Week 3:10. Pittsburgh Steelers- The Steelers lost on the road to the lowly Bears, and continue to struggle away from Heinz Field, but Colin still thinks they’re good enough to sneak into the Top 10. 6. Philadelphia Eagles – Philly leads the NFL in time of possession (34:12), and is tied for 3rd in the league in 3rd-down conversion percentage (48.8%), both stats that Colin heavily values. They also lead the league with 53 plays of 10+ yards. Colin thinks they have one of the best offensive/defensive line combos in the NFL, and likes what he sees in Carson Wentz, so they come in at 6. 2. New England Patriots – The Patriots are firing on all cylinders offensively, and Tom Brady looks better than ever. Brady leads the NFL 1092 pass yards and touchdowns (8). As a team, New England ranks 1st in total offense (440.7 net ypg), 1st in pass offense (340.0 pass ypg), and 2nd in scoring (33.0 ppg).Their 20 plays of 20+ yards is tied for 1st in the NFL, and they only have one giveaway on the year. Their most glaring weakness is a lack of a pass rush, which was exposed in their Week 1 loss to the Chiefs. But, Belichick and Brady are still Belichick and Brady. Pats at 2. 4. Dallas Cowboys –  Dallas bounced back from a dud against Denver with a win on the road in Arizona, and Colin loves their offensive balance, but their defense has been unexpectedly great. Their 11 sacks leads NFC, and Demarcus Lawrence leads the NFL with 6.5 sacks.Dak Prescott hasn’t thrown a pick in 2 of 3 games, and Ezekiel Elliott looks like he’s getting going. The Cowboys are going to be a tough out in the playoffs if their clicking.last_img read more

Mitchell’s over inflated sense of self importance over his records and complete lack of awareness that he’s an all around giant D-bag are beyond what anyone could dream up in a Hollywood writers’ room.last_img read more
