Apples iPad Vs Lenovos IdeaPad U1Hybrid Notebook w Video

first_img Citation: Apple’s iPad Vs Lenovo’s IdeaPad U1Hybrid Notebook (w/ Video) (2010, January 28) retrieved 18 August 2019 from https://phys.org/news/2010-01-apple-ipad-lenovo-ideapad-u1hybrid.html The iPad has no multitasking capabilities which can be counter-productive; how can you copy and paste between two application? This is a basic requirement that is even available in some smartphones.No Flash support. Many websites use flash for video streaming as well as movie content providers like Hulu, Fancast, and others. The screen ratio is 4:3 and is not HD ready. The screen itself displays 132 ppi as compared to the iPhone’s 163 ppi. This leaves much to be desired when viewing streaming video.The good news is the iPad has optional keyboard dock, camera connection kit and an Apple-designed case; all of which will raise the basic cost.In the 2010 CES, Lenovo announced their IdeaPad U1Hybrid Notebook. This device has unique detach-and-converge design that lets users easily remove the screen to instantly switch from clamshell mode to a multi-touch slate tablet. Lenovo’s amazing Tablet/PC Hybrid brings a tablet and a PC together in an amazingly elegant way. It’s a tablet. It’s a notebook computer. In the clamshell mode the ideaPad runs Windows 7 Home Edition and when detached, in the tablet mode, runs Skylight OS. Skylight OS is a custom user interface by Lenovo built on top of the Linux kernel. Since both OS’s support Adobe Flash there’s no problems watching flash multimedia in clamshell or tablet mode.Both operating systems also provide users with a wide range of existing applications that are not found in the iPad except for existing iPhone apps.Of course these are not the only two touch tablets that we will see in 2010. This year we can see completion heating up between eReaders and touch tablets. The winner will have to be a device that is both innovative and affordable.

Start up creates a nofocus point and shoot camera

first_imgLytro is having the cameras made itself and did not disclose the planned price. Citation: Start up creates a ‘no-focus’ point and shoot camera (2011, June 22) retrieved 18 August 2019 from https://phys.org/news/2011-06-no-focus-potentially-3d-camera.html (PhysOrg.com) — If you have ever used a “Point and Shoot” style of camera in the last few years then you know that that term is a misnomer because unless you are using a disposable camera you are going to be waiting for that camera to auto-focus and that focus can take up to 45 seconds to find its focus and allow you to take a picture. It is annoying to say the least if the action that you wanted a picture of can’t be stopped like a posed photo. Since that focus can mean that you may miss a winning goal or a really cute moment it can be more than just annoying. This document is subject to copyright.

The company is named Lytro and it is based on the work of Dr. Ren Ng whose dissertation on light-field technology was published five years ago to accolades by his Alma Matter Stanford University. Dr. Ng has recently received $50 million in funding in order to create his company, which is about to launch a digital camera that is free of the focus factor, by getting all of the information about the surroundings that is possible. “Shoot now, focus later,” Dr. Ng said today in a blog post describing this innovation. The machine takes a photo by getting as much of the information about the field of light in the general area as possible. This will allow users to adjust the focus as many times as they want after the photo has been taken. It will also allow users to alter a photos level, and depending on your setup may even allow users to create images that are three-dimensional. Explore furtherlast_img read more

Researchers find slime mold feeding fronds have memristance

first_img Memristance, first described by Leon Chua back in 1971, is where a material has the unique property of undergoing a change in electrical resistance as current is applied. When applied in one direction, resistance increases; when applied in the other, it decreases. More importantly perhaps, such materials also have the remarkable ability to “remember” how much resistance was being applied when the power was turned off. When electricity is restored, the material has the same resistance it had at its prior stopping point. For that reason, researchers have been interested in finding a way to use memristance materials in computers. To date, some progress has been in creating artificial materials with memristance —a team at Hewlett Packard, for example, has been successful in creating a type of switching memristor using titanium dioxide.To better understand how memristance materials work, researchers have turned to nature for examples. In this new effort, the researchers applied voltage to feeding frond samples of the slime mold and found that it conformed to the criteria that describe a memristance material. The finding, they suggest, should help in the development of bio-electronic circuits that can be grown rather than created from other materials.The team’s work builds on prior studies that have shown slime molds capable of finding the shortest path to a food source, which the researchers note could be useful in computer algorithms that seek to perform similar tasks. They acknowledge that it isn’t likely that slime molds will one day sit at the heart of future computers systems, of course, but suggest that biological materials similar to that found in molds could one day be used to create computers unlike anything that exists today.

Researchers discover antifreeze protein with water filled core

first_img(Phys.org) —A team of researches with Queen’s University, in Canada has found that the antifreeze protein Maxi, defies the normal expectations of a protein by having a core filled with water molecules. In their paper published in the journal Science, describing their research with the protein, the team suggests that Maxi may cause scientists to rethink the mechanisms and kinetics of protein folding. Kim Sharp describes the research effort and the team’s finding in a Perspective piece in the same journal. Antifreeze proteins are useful because they absorb to the surface of ice crystals and in so doing, prevent them from growing—solutions that harbor them thus remain in a liquid state at temperatures below freezing. Proteins come about as a result of a process known as folding—aliphatic and aromatic side chains pack together forcing water out—without water in the core the protein prevents ice crystal formation. Because the cores that result are hydrophobic they are known as being anhydrous, and scientists believe they come about through one of two processes: evaporation or expulsion. In this new effort the researchers have turned the understanding of antifreeze protein folding on its head, as Maxi, when its formed via folding, doesn’t force all the water out of its core, instead it retains 400 water molecules. This discovery has caused the research team to question whether the prevailing views regarding protein folding in general are correct.With water in its core, it would seem that Maxi would allow ice crystal formation, but that’s not the case, and it’s because Maxi has hydrophobic molecules on the outside of its structure, thus the molecule appears almost as if inside out. With that the case, the question arises of how the protein arrives at its structure through folding? The researchers don’t know but suspect it aligns more with the protein folding that normally follows the expulsion approach as it doesn’t seem possible that such a protein could develop due to an evaporative process.The researchers learned of the odd structure of Maxi by looking at it at 1.8-angstrom resolution—close enough to count the water molecules inside and to see that they were effectively trapped in a way that allowed for stabilization—the protein is longer than most antifreeze proteins. Sharp suggests that further study of Maxi will lead to a better understanding of the true mechanics of protein folding and ultimately a clearer view of protein formation in general.

We report the crystal structure of an alanine-rich antifreeze protein that retains ~400 waters in its core. The putative ice-binding residues of this dimeric, four-helix bundle protein point inwards and coordinate the interior waters into two intersecting polypentagonal networks. The bundle makes minimal protein contacts between helices, but is stabilized by anchoring to the semi-clathrate water monolayers through backbone carbonyl groups in the protein interior. The ordered waters extend outwards to the protein surface and likely are involved in ice binding. This protein fold supports both the anchored-clathrate water mechanism of antifreeze protein adsorption to ice and the water-expulsion mechanism of protein folding. Explore furtherlast_img read more

Researchers use cryoelectron microscopy to learn how DNA wraps tightly around nucleosomes

first_img(Phys.org) —A team of researchers working at the Chinese Academy of Sciences, in Beijing, has used cryo-electron microscopy to reveal how it is that DNA wraps so tightly around nuclesomes. In their paper published in the journal Science, the team describes how they managed to identify the path of linker DNA. Andrew Travers offers a Perspective piece in the same issue explaining the team’s findings and what it might mean for DNA research in the future. A specific ratio of DNA packaging proteins ensures normal gene expression during early embryonic development DNA in eukaryote cells (those with a nucleus surrounded by a membrane) comes packaged inside of what are known as nucleosomes, which are materials made up primarily of histone proteins—together they form chromatin. Prior research has shown that nucleosomes exist (due to folding) as coiled structured helix shapes, approximately 30nm in diameter. Inside each helix is a “linker” histone—a fiber that runs the length of the helix. Up until now, the molecular makeup of the linker has been a bit of a mystery, with competing researchers suggesting different ideas. In this new effort, the researchers in China appear to have settled the debate using cryo-electron microscopy, a form of transition electron microscopy where the material being studied is kept at cryogenic temperatures. Examination by the team revealed the linker histone fiber to be constructed from arrays of 12 nucleosomes.The arrayed nucleosomes constitute the longest segment of chromatin observed to date, and help explain how it is that genomes can be packaged, yet remain easily accessible. The researchers found that the linker histone (type H1) binds nucleosomes together into structures known as tetranucleosomal units—they in turn form double-helical structures similar to the DNA that they serve to package. The team notes that the binding that occurs results in stacking, which is how the double-helix is able to form. More information: Cryo-EM Study of the Chromatin Fiber Reveals a Double Helix Twisted by Tetranucleosomal Units, Science 25 April 2014: Vol. 344 no. 6182 pp. 376-380. DOI: 10.1126/science.1251413ABSTRACTThe hierarchical packaging of eukaryotic chromatin plays a central role in transcriptional regulation and other DNA-related biological processes. Here, we report the 11-angstrom–resolution cryogenic electron microscopy (cryo-EM) structures of 30-nanometer chromatin fibers reconstituted in the presence of linker histone H1 and with different nucleosome repeat lengths. The structures show a histone H1-dependent left-handed twist of the repeating tetranucleosomal structural units, within which the four nucleosomes zigzag back and forth with a straight linker DNA. The asymmetric binding and the location of histone H1 in chromatin play a role in the formation of the 30-nanometer fiber. Our results provide mechanistic insights into how nucleosomes compact into higher-order chromatin fibers.

Credit: Institute of Biophysics, Chinese Academy of Sciences The findings by the research team point out the important role H1 linker histones play in stacking nucleosomes, which, they note, serves to make chromatin compact. They also note that nucleosomes can fold into other helical structures under different circumstances, which opens the door to other research efforts in the future. Also as Travers points out, their results lead to other questions, such as whether the structures they’ve uncovered correspond to the fiber in its natural state or if there are others. There’s also the question of what happens when the helix is unwound, does it cause changes to internucleosomal interactions? Finding answers to such questions will likely be the focus of the research team in China as well as others working in the field for many years to come.

Best of Last Week – New model for dark matter Martian clouds

first_img In unrelated space news, Mars rover Curiosity snapped images of Martian clouds—two years on, the rover is currently driving toward some hills “to do some geology work & also search for clouds,” NASA reported via Twitter. The agency also reported that it had successfully tested the most complex rocket parts ever designed, created using additive 3D printing.In technology news, researchers in Virginia have developed a non-volatile type of memory that improves energy efficiency by two orders of magnitude—it’s based on using voltage generated stress. Meanwhile a partnership between two research groups has resulted in producing the first graphene-based flexible display. It’s still just a prototype, of course, but it does offer perhaps a glimpse of what might be coming to consumers sooner rather than later.In completely unrelated news, a team working in Gibraltar has claimed that cave art was made by Neanderthals, which would make it the first known examples of Neanderthal rock art. Not everyone is as sure as they are. Also, researchers at the University of Manchester and King’s College in the U.K. wonder—is type 2 diabetes really “diabetes” as it’s currently understood? They suggest distinctions be made between diagnosing and treating the two types of the disease.And finally, in a bit of science fiction meeting reality, a team of researchers has demonstrated direct brain-to-brain communication in human subjects. They hooked up volunteers in India and France with brain wave reading gear, then connected them together via the Internet. A volunteer on one side was asked to think of the words “hola” and “ciao” while a volunteer on the other end listened. The team reports that the person on the receiving end was able to “hear” what the other person thought. Where this might lead is anyone’s guess but it most certainly opens the door to whole host of unanswerable questions.

She had also instructed party leaders to hold meeting places within 72 hours where the BJP had organised rallies to counter their lies politically which the BJP leaders are circulating deliberately. Accordingly, a huge rally under the leadership of Suvendu Adhikari will take place in East Midnapore on Sunday. Derek further maintained that Shah has wrongly said that “Mission Nirmal Bangla” is a copy of the Centre’s Swachh Bharat mission. He said: “Shah should know that Mission ‘Nirmal Bangla’ was started in 2013 much ahead of Swachh Bharat Abhiyan which started on October 2, 2014. Nadia was the first district in the country to become Open Defecation Free. More than 95 percent of the districts in Bengal have become ODF.” O’Brien also added that the BJP national president has stated that there is no industrial growth in Bengal. The real picture is that Bengal’s growth is 11.4 percent which is more than the national growth at 4.4 percent. “The state ranks first in MSME, ease of doing business and skill development,” he said. Rebutting Shah’s claim that no Durga and Saraswati pujas are allowed in Bengal, Derek said more than 30,000 community Durga pujas are held in Bengal and Saraswati puja is held in more than 10,000 schools. Moreover, a grand carnival is held on Red Road every year to showcase immersion. Demolishing Shah’s claim that cows are being smuggled through the Indo-Bangladesh border, Derek stated that the border fencing is the responsibility of the Home Ministry.last_img read more

College rebuts Shah theory claims vandalism outsiders handiwork

first_imgKolkata: While BJP’s national president Amit Shah was busy alleging that Vidyasagar College was vandalised by members of Trinamool Chhatra Parishad (TMCP), the college union authority has clearly denied the allegations and stated that it was outsiders who had pelted stones and vandalised the campus later. On Wednesday in a press conference at Delhi, Shah claimed while holding a picture in his hand that TMCP members had attacked BJP first and later they themselves vandalised the college and broke the statue of Vidyasagar to gain sympathy.

Significantly, none of them were Bengalis either and so did not know who Iswar Chandra Vidyasagar was. “Each and every miscreant had come from outside with bricks, bamboo sticks and other such weapons. They had set fire to the bikes parked inside and later vandalized the statue,” he said. Shah had also raised questions on why the college was open till 7:30 pm. However, according to college authorities and local residents, the BJP leader’s claim is totally false as the incident occurred around 6:30 pm. Elaborating on this, Kundu said: “Though official college timing is till 5:45 pm, we have pending work which need to be done even after scheduled college hours. Does he know everything?” Also Read – Lightning kills 8, injures 16 in stateThe teachers and students of Vidyasagar College also protested against the statements made by Shah on Wednesday. “We saw what happened here on Tuesday. Where was he? Even every single news channel is showing who had vandalised the college. How can he say that our students had done this?” said an irate teacher. Vidyasagar College is the first non-government college in India, which started its journey in 1859. Initially named as Calcutta Training School, it was founded by Thakurdas Chakraborty. In 1859, the school was renamed as Metropolitan Institution. In 1872, Metropolitan Institution was granted affiliation by Calcutta University and named after Iswar Chandra Vidyasagar. Several eminent personalities such as Swami Vivekananda, Acharya Prafulla Chandra Ray, Acharya Jadunath Sarkar, Ram Manohar Lohia and Babu Jagjiban Ram were alumni of the storied institutionlast_img read more

Stomach issues signal future mental problems

first_imgChildren who face adversities – such as parental separation – are more likely to suffer from gastrointestinal symptoms which may lead to mental health issues in later life, a study has found. The study, published in the journal Development and Psychopathology, found that gastrointestinal symptoms in children may have an impact on the brain and behaviour as they grow to maturity. “One common reason children show up at doctors’ offices is intestinal complaints,” said Nim Tottenham, a professor at Columbia University in the US. Also Read – Add new books to your shelf”Our findings indicate that gastrointestinal symptoms in young children could be a red flag to primary care physicians for future emotional health problems,” said Tottenham. Scientists have long noted the strong connection between the gut and brain. Previous research has demonstrated that a history of trauma or abuse has been reported in up to half of adults with irritable bowel syndrome (IBS), at a prevalence twice that of patients without IBS. Also Read – Over 2 hours screen time daily will make your kids impulsive”The role of trauma in increasing vulnerability to both gastrointestinal and mental health symptoms is well established in adults but rarely studied in childhood,” said Bridget Callaghan, a post-doctoral research fellow at Columbia. Animal studies have demonstrated that adversity-induced changes in the gut microbiome influence neurological development, but no human studies have done so. “Our study is among the first to link disruption of a child’s gastrointestinal microbiome triggered by early-life adversity with brain activity in regions associated with emotional health.” The researchers focused on development in children who experienced extreme psychosocial deprivation due to institutional care before international adoption. Separation of a child from a parent is known to be a powerful predictor of mental health issues in humans. That experience, when modelled in rodents, induces fear and anxiety, hinders neurodevelopment and alters microbial communities across the lifespan. The researchers drew upon data from 115 children adopted from orphanages or foster care on or before approximately they were two years old, and from 229 children raised by a biological caregiver. The children with past caregiving disruptions showed higher levels of symptoms that included stomach aches, constipation, vomiting and nausea. From that sample of adoptees, the researchers then selected eight participants, ages seven to 13, from the adversity exposed group and another eight who’d been in the group raised by their biological parents. The children with a history of early caregiving disruptions had distinctly different gut microbiomes from those raised with biological caregivers from birth. Brain scans of all the children also showed that brain activity patterns were correlated with certain bacteria. “It is too early to say anything conclusive, but our study indicates that adversity-associated changes in the gut microbiome are related to brain function, including differences in the regions of the brain associated with emotional processing,” said Tottenham.last_img read more

Park Street Metro incidents Station masters transferred

first_imgKolkata: The Metro authorities transferred the station master of Park Street Metro station and has decided to set up two extra entry-exit gates on the platform through which trains travel from Noapara to Kavi Subhas. The move, according to sources, comes after two major untoward incidents in Park Street within a period of one month.Last Tuesday, a girl commuter complained that the rake she was travelling in, started moving with her shoulder stuck outside the doors. Aatreyee Bhattacharya took to Twitter to narrate her ordeal. The Train Information Management System (TIMS) data of the Metro, however, revealed that the door in which she got stuck had remained open for seven extra seconds and the train started moving only after it was closed. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: Mamata”Park Street is one of the busiest stations in our route and it is the only station in the entire route where the ticket counter and the platform is located on the same floor. People, while purchasing tickets, can see whether the train is in the platform and the tendency of rushing to catch the train is obvious. So we have decided to install two extra gates to facilitate passenger movement,” a source with the Metro authority said. It may be mentioned that on July 13, Sajal Kanjilal, a resident of Kasba, was killed while trying to board a Kavi Subhash-bound Metro train from Park Street station during busy office hours when the rake started moving with a portion of his body hanging outside the sliding doors. Apart from Park Street, station masters of Netaji and Kavi Subhas Metro stations have also been transferred.last_img read more
