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.

This result complements previous findings on memristive properties of other living systems (human skin and blood and leaves) and contributes to development of self-growing bio-electronic circuits. © 2013 Phys.org (Phys.org) —Researchers at the University of the West of England have found that the feeding fronds on a type of slime mold have a property known memory resistance, which has been shortened to the term memristance. In their paper uploaded to the preprint server arXiv, the team describes how experiments on the slime mold P. polycephalum demonstrated the unique property previously only found naturally in human sweat glands, blood and some tree leaves.last_img read more

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

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. (Phys.org) —Most of the big news in physics this past week came from astrophysicists, most notably Mikhail Medvedev—he’s come up with a new model for dark matter, suggesting it’s likely a new type of elementary particle that doesn’t fit the standard model.

Card skimming case Police suspect involvement of Nigerian gang

first_imgKolkata: The police are suspecting that a gang comprising some Nigerian nationals was behind the unauthorised withdrawal of money from various bank accounts, after skimming of debit cards to get details.The modus operandi of the crime made the police suspect that there could be a “Nigerian” gang behind the entire operation. Preliminary investigation has revealed that the cash was withdrawn using the debit card details from certain places in Delhi. In most of the previous such cases in which money was withdrawn from Delhi, involvement of a “Nigerian gang” was found. Also Read – Rain batters Kolkata, cripples normal lifeThe police have gone through the video footages of surveillance cameras installed in three ATM counters at Mallick Bazar, Golpark and Elgin Road. In these three counters, skimming machines were found fitted at the slot of the ATM machines, where one needs to swipe cards to withdraw money. The video footages have shown a person entering the ATM counter to fit the skimming machine. He had his face covered.Police suspect that the same person had installed skimming machines in all the three ATM counters. In one of the video footages he was found covering his face with a handkerchief. In another he was wearing a cap and in the third ATM counter, he was seen wearing sunglasses. As a result, the police have not got a clear picture of the person and so are preparing his portrait parle.
