(PhysOrg.com) — Biometric security is always a field of interest for those people who need to keep your data secure. Currently, it is used in a wide variety of high security applications, mostly by large companies with large amounts of customer data to protect. But, in the future you may be able to use a retinal scan to sign into your favorite social networking sites such as Facebook, and your email.

They have created a new product, called EyeLock, which was first unveiled at the Finovate conference in San Francisco. The device, which is a portable iris-scanner about the size of a business card, is also a USB drive. This allows it to work with a variety of machines. Once the user has installed a special program they can choose which applications to EyeLock. You can give the system software your log in information for those sites. The next time you want to sign into your favorite site all you have to do is hold the scanner in front of your eye. The tool will then automatically log you into your site. Users who wear glasses will be happy to find out that they do not have to remove them in order to complete the scan. This will be the first time that iris scanning technology will be an option for users on the consumer market. Since it will allow for the tracking of multiple log on the devices will no doubt be convenient. Though it may make signing onto your favorite sites more secure users should be aware that if they lose the device they will have a lot of different passwords to change since no device is un-hackable and the passwords are stored on it.
Explore further The team, led by Pablo Jarillo-Herrero, made their discovery by creating several so-termed p-n nanojunction devices (the boundary that is formed between P and N type semi-conductors) in their lab and then taking careful measurements of each type using laser light to measure the resultant photocurrent produced. They found that as the power to the laser was increased, so too did the photocurrent. During their experimentation, they found that they could produce up to 5 mA/W, even at a low temperature; a number that is 6 times higher than has been demonstrated with any other optoelectronic device based on graphene. They believe this occurs because the electrons in the graphene aren’t able to transfer their heat very well due to poor coupling with other materials.Graphene is a one-atom thick layer of carbon that has all manner of unique properties and because of that, new applications for it have been announced periodically since its discovery in 2004. Until now though, very little progress had been made in using it in optoelectronics devices. This new property, called a hot-carrier regime by the team, is unusual because it’s normally only seen in other materials at very cold temperatures. With graphene, however, the effect occurs at low, medium or high temperatures making it a very good candidate for practical applications such as photo-sensing or as part of devices that harvest the energy in sunlight.The team notes that the discovery of this new property of graphene they describe is likely just the first step in a very long journey. Much more research needs to be done to find out such things as just how efficient can a process using it be made, or what if more layers of graphene are integrated into a device. They plan to continue work in this area, as will others no doubt, now that this new property has come to light. More information: Hot Carrier–Assisted Intrinsic Photoresponse in Graphene, Science DOI:10.1126/science.1211384ABSTRACTWe report on the intrinsic optoelectronic response of high-quality dual-gated monolayer and bilayer graphene p-n junction devices. Local laser excitation of wavelength λ = 850 nm at the p-n interface leads to striking six-fold photovoltage patterns as a function of bottom- and top-gate voltages. These patterns, together with the measured spatial and density dependence of the photoresponse, provide strong evidence that nonlocal hot-carrier transport, rather than the photovoltaic effect, dominates the intrinsic photoresponse in graphene. This regime, which features a long-lived and spatially distributed hot carrier population, may open the doorway for hot carrier–assisted thermoelectric technologies for efficient solar energy harvesting.Preprint on arXiv: arxiv.org/abs/1108.3826 © 2011 PhysOrg.com Graphene shows unusual thermoelectric response to light (PhysOrg.com) — A team comprised of researchers from MIT and Harvard has discovered yet another unique and useful property of graphne, this time it involves optics. As they describe in their paper published in Science, when light, or in this case a laser, is aimed at an object with a graphene surface its electrons get hot and remain so for longer than the rest of the object. This property opens up the door to all kinds of possibilities for new kinds of superfast photo-detectors and energy harvesting technology. This document is subject to copyright.

In their paper published in the journal PLUS ONE, the team describe the baculum fossils in great detail and offer theories as to why the bear had such a large penis.

PLoS ONE 8(9): e73711. DOI: 10.1371/journal.pone.0073711AbstractThe fossil bacula, or os penis, constitutes a rare subject of study due to its scarcity in the fossil record. In the present paper we describe five bacula attributed to the bear Indarctos arctoides Depéret, 1895 from the Batallones-3 site (Madrid Basin, Spain). Both the length and morphology of this fossil bacula enabled us to make interpretative approaches to a series of ecological and ethological characters of this bear. Thus, we suggest that I. arctoides could have had prolonged periods of intromission and/or maintenance of intromission during the post-ejaculatory intervals, a multi-male mating system and large home range sizes and/or lower population density. Its size might also have helped females to choose from among the available males. Explore further This document is subject to copyright.

Many male mammals have a bacula, also known as a penis-bone, to assist in reproduction. The stiffness of the bone allows for easy insertion of the penis into the female’s vagina (as contrasted with blood pressure to maintain an erection as occurs with humans.) All bears have a bacula, but what sets I. arctoides apart from modern species was its size. Scientists have found many fossil bones from the bears and thus have a clear idea of its overall size. The bear was on average about the size of modern European Brown bears (265.74 kg for males and 137.30 kg for females), yet its bacula was longer than the much larger Polar or Kodiak bears that exist today. Four of the five specimens found were from adult males—together their baculum averaged 225.26 mm in length.Bacula finds are rare in archeological research, their thinness makes them prone to breaking, and quite often they are mistaken for rib bones. Thus finding 5 wholly intact specimens was a noteworthy find in and of itself—that they represent such a large penis bones relative to body size is perhaps even more remarkable.The researchers can’t say for sure why the ancient bears (they lived approximately 12 to 5 million years ago) had such large penises, but offer some theories. They suggest that a larger penis would allow for longer copulation, helping to ensure that the female became impregnated. A longer penis would also help to guide the sperm that was released more directly to its target, once again, offering higher reliability of impregnation. The researchers also suggest that such a long penis might even have allowed a male to remove plugs deposited by prior males, ensuring their DNA would win over. And finally, they propose that females may have grown to prefer males with a larger penis for these very same reasons, thus ensuring that males with the largest penises would predominate, leading to longer and longer bacula for the species as a whole.

Darjeeling: The Himalayan Plantation Labour Union (HPWU), affiliated to the Gorkha National Liberation Front has stopped the dispatch of premium first flush manufactured tea from the Rangili-Rungliot tea estate in Darjeeling, protesting against the non-payment of dues to the tune of more than Rs 1.5 crore accumulated since 2011. “The management of the tea estate has not paid the second instalment of bonus as per agreement, along with other dues. Despite repeated requests the management has turned a deaf ear. We have stopped the dispatch of manufactured tea from the garden since April 14″, stated JB Tamang, general secretary of HPWU. Also Read – Heavy rain hits traffic, flightsThe dues include gratuity, provident fund, leave travel allowance, salary, wages, staff kitchen allowance, JCO and tea makers salary, medical bill and LTA of temporary workers.”Till February 14, 2018, the accumulated due was to the tune of Rs 1,45,76,481. Dues have continued accumulating since then. Gratuity has not been paid since 2011″, added Tamang.HPWU on Wednesday had submitted memorandums to the District Magistrate, Superintendent of Police and the Assistant Labour Commissioner of Darjeeling calling for legal action to be taken against the management.

However, if they try to commence dispatch forcefully, we will stop the dispatch till the total due amount is paid up”, cautioned Sudesh Rai, branch president of HPWU.The union has made an appeal to other trade unions to join the agitation in order to create adequate pressure.The tea estate has 350 workers and around 100 staff and sub staff. It produces 1,60,000 kg of tea annually. The trade Union had earlier threatened to stop the dispatches of manufactured tea in all the 87 tea gardens, if the gardens fail to give the stipulated fringe benefits to the workers by April 21. “As per the Plantation Labour Act, workers working for 120 days in a year are entitled to fringe benefits. However, the management of the gardens is only providing fringe benefits to workers who have worked for at least 180 days. This needs to change. Till now, no tripartite meet has been called to resolve this issue. We will stop dispatch of tea in all the tea gardens in the Darjeeling hills from April 21 if our demands are not met”, threatened Tamang.
Kolkata: Prakriti Organic Farmfresh India Ltd. (POFIL) is organising a three-day carnival of products at Salt Lake City Centre which will be inaugurated by state Technical Education, Training and Skill Development minister Purnendu Basu on Friday. “The state government has identified 120 clusters across the state under which more than 7,500 farmers have been involved in the production of organic vegetables. The farmers who have worked in this area have got assistance under the “Paramparagat Krishi Vikas Yojana” (PKVY) — a scheme under which farming is promoted through adoption of organic village by the cluster approach and PGS certification. Our aim is to enable people of the state to have organic products at a reasonable rate. The most important part in this venture has been the motivation of farmers in the state to adopt organic farming and the Bengal government has been successfully able to do the same,” said Mannu Chowdhary, Managing Director of POFIL. Also Read – Heavy rain hits traffic, flightsApart from a plethora of organic vegetables and fruits, the special attraction will be two varieties of mangoes — Amrapali and Mallika from Bankura and also export quality watermelons from Bankura. The Himsagar and Langda varieties of mango from Malda will also make it to the three-day carnival along with organic tea from Darjeeling and three varieties of rice — Tulaipanji, Gobindobhog and Black Rice. The state government is laying a lot of emphasis on production of organic vegetables as various studies have highlighted excessive use of pesticides in normal ones. The state is also holding two markets of organic vegetables — one at Bidhan Sishu Udyan in Ultadanga and another at Baguiati weekly.”We are processing the products in a scientific manner and packaging it mentioning the name of the farmer who has produced that particular vegetable so that customers can have a direct link with the farmer. A number of farmers will also be present at the carnival,” Chowdhary added. Organic products from Uttar Pradesh will also be a part of the event.
Interpreting the data collected from volunteers’ own smartphones — which has the potential to emulate randomised trials — can boost research into human behaviour, finds a new study.Fani Tsapeli from the University of Birmingham, and her colleague and Mirco Musolesi from the University College London used user-generated data, harvested from their phones to evaluate the cause of increased stress levels of participants. Most of the earlier research works relying on smartphones focused on detecting factors in the features extracted from smartphone data. But that pure correlation analysis did not provide for a sufficient understanding of human behaviour.

By contrast, they found that reduced working hours only slightly impact stress. The conclusions cannot be extended to the general population due to the small sample size. But the approach has been validated and shows great promise for further studies.The study was published recently in EPJ Data Science.
