(PhysOrg.com) — Flexible and translucent organic displays have been developed by TDK for use in “bendable” mobile phones and other gadgets, and the bendable display is expected to go into mass production by the end of 2011. Citation: Flexible and transparent OLEDs from TDK (w/ Video) (2010, October 6) retrieved 18 August 2019 from https://phys.org/news/2010-10-flexible-transparent-oleds-tdk-video.html The displays, developed by TDK, use organic light-emitting diode (OLED) technology, which means very low power use because they are self illuminating. Having no back light enables the displays to be ultra thin (at 0.3 mm), but TDK’s flexible display is also super light because it is manufactured using a film substrate rather than metal or glass.The resolution of the flexible screen is currently 256 x 64, and it can be up to 10 cm tall and installed on curved surfaces of less than 25 mm radius. Being flexible would make the display more resistant to cracks or breakages. Image credit: Tech on. The translucent display is 320 x 240 resolution, 50 percent translucent, and up to 10 cm tall. The display uses one-way light emission, meaning the user of the device is able to see the text or images displayed, but people on the other side cannot because the light output is set to the direction of the text, although they can see through the display. The translucent display uses a glass substrate, but a film transparent display is planned for 2012.Several other companies have previously demonstrated flexible screens, such as Sony, but TDK’s flexible display is expected to be in mass production by the end of next year, making it the first to actually reach market. The translucent screen is already being mass produced.The OLEDs were unveiled at the Cutting-Edge IT & Electronics Comprehensive Exhibition (CEATEC) 2010 in Tokyo, Japan yesterday.

This no-glasses 3-D sheet from Sony is supported by face-tracking technology, so that the viewer can get an optimized 3-D image with pixels shifted around behind the lens. The Vaio viewing process with this sheet will use face detection to track the position of the viewer’s head via built-in web camera; images will be adjusted for clarity to make sure the viewer gets and maintains the 3-D experience.The Vaio S series will debut in Europe next month and the price is expected to be about $1,000. The price of the sheet accessory is said to be $183.The 3-D option via lenticular sheet is just one of several 3-D products that Sony announced. The Sony Vaio L Series all-in-one 3-D touchscreen multimedia PC, the 3-D-capable Sony SMP-N200 Network Media Player, and the Sony VPL-VW95ES 3-D projector were part of the company’s showcase.As a number of correspondents covering the show are saying, 3-D bells and whistles on viewer devices, on projectors, on televisions, and on computers, are all being promoted by consumer electronics kingpins as the way to get to consumers’ hearts in the hope that enhanced viewing experiences will help products move.Meanwhile, the news portal Tech-On! points out that a lenticular-system sheet to make visuals appear in 3-D made a June debut, with the announcement by Global Wave of its lenticular system sheet called Pic3D. This product from Global Wave is a lenticular lens film that one can add to a smartphone, tablet or laptop screen to turn it into a glasses-free 3-D display. Global Wave says that the product was announced last year but is now improved.

via Guardian Up till now, most in the field have agreed that the most recent evidence of early man hunting animals for meat to eat was at a site in Germany that showed horses being brought down with long spears, likely thrown from trees, approximately 400,000 years ago. They’ve also agreed that early man was almost certainly eating meat before this time, but only from carcasses left over from other hunters such as lions.In this new study, Bunn said that in comparing the types of animals and their ages eaten by lions and other carnivores today with the types of meat that were being eaten by early man, it’s clear that our descendants were not eating leftovers, but were instead going out and getting their own meat.When leopards and lions hunt down and eat the larger species of antelope, for example, they tend to go for the young or old, as they are generally easier to bring down. Evidence at the Tanzania site however shows that early humans were eating such animals that were in their prime. On the other hand, when the big cats go after the smaller species of antelope, they tend to capture those in their prime, while early man seemed to prefer the young and the old. These findings, Bunn said, show very clearly that the animals that early man was eating were not brought down by other animals but were killed by hunting them themselves.The evidence brought forth by Bunn could mean the rewriting of some human evolution theories regarding how it was humans developed such complex brains, and why. Some have suggested it came about as a result of the evolution of social communities and the challenges it created, with early man eating a lot of vegetative material and the odd bit of meat that could be scavenged. If early man was hunting though, that would mean he was using his brain to development new ways to do it more efficiently, particularly if it was done in groups, which would seem the most likely scenario as it generally results in the most success.

He said evidence there indicates that early man was hunting in an organized fashion some two million years ago. More information: This document is subject to copyright.

Cranial modification is the process of altering the physical characteristics of the skull—throughout history, it has been done by binding the heads of babies when their skulls are still soft. In most instances, the goal was to elongate the skull—it is actually still practiced today in some parts of the world. Bindings have typically been in the form of cloth or wood boards. It is not known why many early cultures engaged in the practice, but some in the field have suggested it is likely a way to mark someone as belonging to an elite or special part of society. In this new effort, the researchers were studying skeletal remains removed from a site called Houtaomuga. The site is believed to have been an ancient Chinese tomb—archaeologists worked at the site from 2011 to 2015. The skeletons were all in a vertically shaped tomb, and there were no obvious gender biases for cranial modification. Twenty-five skeletons were found in all, 11 of which had evidence of intentional cranial modification. Four of the skulls were from adult males, one was from an adult female, and the rest were from children. The bones were not placed in the tomb at the same time, however, they were interred over the course of 7,000 years, from 12,000 to 5,000 years ago.The researchers report that there was very little evidence that might provide an explanation for the binding of babies’ heads, but suggest it likely was an indicator of wealth or high status. Some of the skeletons were buried with artifacts that suggested as much, such as pottery. They report also that they plan to continue digging in the general vicinity of Houtaomuga to find out if there are other tombs in the area, and if so, whether they have more examples of ancient cranial modification.

A girl in class 10 writes ‘it feels really sad to know you all feel that women are inferior and not capable of doing anything’. Another girl writes ‘… but this world seems to suppress girls and dominate us, which is stupid’. Letters like these are part of an exhibition that aims to introduce visitors to what concerns these young girls.The title of the exhibition comes from American author and poet Maya Angelou’s collection of poems And Still I Rise as it goes with its central theme: raising awareness of gender discrimination and its impact on limiting opportunities for women worldwide. Also Read – ‘Playing Jojo was emotionally exhausting’What makes the exhibition different is that it also features artworks inspired by the writings of girls aged 14-18 from countries like India, China, Britain and Mexico in which they openly address the many fears, insecurities and stereotypes that societies around the world are building.The letters grew out of a workshop conducted by a Delhi-based charity, Creative Services Support Group (CSSG), which invited around 200 schoolgirls in the city to pen down their thoughts on how girls are perceived in society and their role in it. The replies opened a pandora box of issues confronting these young girls and provided a gateway to their minds. The exhibition is on till April 12 at Instituto Cervantes de Nueva, Hanuman Road.
Kolkata: West Bengal would shortly issue a notification to regulate the companies involved in direct selling of products in the state, as directed by the Central government, state Consumer Affairs minister Sadhan Pande said on Tuesday. The minister said the department would add certain clauses to the organisations involved in direct selling after thoroughly studying their product base and the line of business.”The Federation of Direct Selling Association (FDSA) had given a requisition to the government of India. The Centre has asked the state governments to accept this by adding certain clauses that suit their economic policies,” Pande said on the sidelines of a conference organised by FICCI CASCADE (Committee Against Smuggling and Counterfeiting Activities Destroying the Economy) here. Also Read – Heavy rain hits traffic, flights”There are several companies who are interested in direct selling their products without spending on advertisements and publicity which would enable them to sell the product to the masses at an affordable cost. We have thoroughly studied the list of products provided by the companies and would issue a notification shortly,” he said. The minister announced that certain definitive clauses would be added so that the consumers do not face any difficulty in buying these products. “Earlier, direct selling was there but we did not have any regulations for the companies involved. Now that issue would be taken care of,” he added.
Kolkata: A college student was arrested on Thursday on charges of demanding money from another who sought admission to Haripal Vivekananda Mahavidyalaya in Hooghly. The accused, a resident of Ghanashyampur in Singur, had demanded Rs 10,000 from a girl assuring her of admission at the institution. The complainant is a resident of Dewanbari village in Singur.The student, Apurba Das, has been arrested and it is learnt that he had visited the student’s residence on more than one occasion with a demand for money.

Following their instructions, she asked him to come to her house and when he reached there on Thursday morning, he was caught red-handed. A few days back, the cops had arrested two students of Peary Mohan College in Uttarpara on similar charges. Recently, amid allegations of extortion of money from students in the name of admissions in colleges, Chief Minister Mamata Banerjee paid a surprise visit to Asutosh College and warned of “strong action” against anyone indulging in irregularities during the admission process. The Student Federation of India (SFI) and the student wing of the BJP took out separate rallies in the city to protest against alleged extortion in colleges.
If you get cravings for chips, sweets and fast-food whenever you are bored, do not blame the situation alone. According to British researchers, people eat more to boost low levels of brain chemical dopamine as they cannot alleviate the boredom in any other way.The results showed that people were more likely to express a preference for unhealthy foods like crisps, sweets and fast food after completing the boring task.“This strengthens the theory that boredom is related to low levels of the stimulating brain chemical dopamine and people try to boost this by eating fat and sugar if they cannot alleviate their boredom in some other way,” said Dr Sandi Mann from the University of Central Lancashire (UCLan). Also Read – ‘Playing Jojo was emotionally exhausting’Mann and colleagues Faye Ibbitson and Ben Edwards conducted two studies of boredom and food choices.In the first study, the team asked 52 participants to complete a questionnaire on their food preferences before and after completing the boredom-inducing task of repeatedly copying the same group of letters.In the second study, they asked 45 participants to watch either a boring or a funny video, during which a range of healthy and unhealthy snacks were available.They found that the participants, who had watched the boring video, ate significantly more unhealthy food.“Health education campaigns can encourage us to make healthier food choices need to take boredom, including boredom in the workplace, into account. Bored people do not eat nuts,” Mann stated.The study was scheduled to be presented at the annual conference of the British Psychological Society this week.
