(PhysOrg.com) — Google has announced a new software development program that lets anyone develop an application for Android devices; it’s called the App Inventor for Android. Google says the software is intended to allow any smartphone user develop Android applications without having any prior knowledge of programming languages. Since Google App Inventor provides access to GPS-location sensor, you can build location apps to determine where you are. You can build a useful app that will show you where you parked your car; never forget where you’re car is parked anymore.According to DailyTech, the New York Times states that Harold Abelson is the Google project leader. Harold Abelson is a computer scientist from MIT on sabbatical at Google. Abelson said, “The goal is to enable people to become creators, not just consumers, in this mobile world.” Abelson also stated, “We could only have done this because Android’s architecture is so open.”The App Inventor was tested by women, sixth grade students, nursing students and many others, none of them majoring in computer science.• PhysOrg.com Android apps (new version available) Google Android Application Inventor makes just about anyone a DIY Android App inventor Inserting buttons, blocks and customizing screen colors is just a click away.

Citation: Tiny robot swarm able to play tunes on a virtual piano (w/ video) (2012, November 26) retrieved 18 August 2019 from https://phys.org/news/2012-11-tiny-robot-swarm-tunes-virtual.html (Phys.org)—Researchers at Georgia Tech’s Georgia Robots and InTelligent Systems (GRITS) Laboratory have succeeded in programming a swarm of very tiny robots to figure out for themselves how to go about playing a tune on a virtual piano displayed on a flat plane. One of the robots is the leader, and knows the tune and where a robot needs to be to create the notes that make up the tune; that information is conveyed to the other robots that make up the swarm, and the result is the playing of the familiar classical tune, Beethoven’s “Fur Elise.” More information: gritslab.gatech.edu/home/2011/ … er-follower-control/ Explore further With swarming, individual members take actions based on the location and actions of those around them. With this new research, the objective was to cause individual members of the swarm to appear at a certain location on the virtual keyboard at a certain time to cause the playing of a note; necessary ingredients to create music. The catch though, was that only one of them, the designated leader, was “told” what those data points were beforehand. Thus, the leader had to convey to the other bots where they needed to be and when. The team added some other elements to the goal to increase the difficulty of the assignment, which should theoretically help in learning more about how to program swarms. They wanted the bots to use the fewest number of themselves possible to play a song together, based on the tempo of the song (and to use the shortest routes possible all while avoiding collisions). If a song is played slow enough, for example, it could be performed by one little robot racing across the virtual keyboard (or by a person using just one finger perhaps on a real piano). As the tempo picks up, it becomes impossible for one bot to get the next note in time for the song to play correctly, thus another bot is added, starting a swarm.What’s remarkable about the playing bots is that the leader doesn’t just tell every other bot where it’s supposed to be, instead, it conveys information to those nearest to it, which in turn convey information to those nearest them, and so on. In this way, each robot is able to work out for itself where it is supposed to be and when – which is how it’s supposed to be, because that’s how swarming works in the natural world. The robots, called Khepera bots by the team, are very small, just 5.5 centimeters across their thimble shaped bodies. Each has a host of sensors, including in their little hats and antenna and two wheels to allow for moving around. The whole idea is to create swarming behavior that mimics that seen in nature with birds, fish, etc.last_img read more

Continuous breathing metalorganic framework with guest selectivity

first_img More information: Elliot J. Carrington et al. Solvent-switchable continuous-breathing behaviour in a diamondoid metal–organic framework and its influence on CO2 versus CH4 selectivity, Nature Chemistry (2017). DOI: 10.1038/nchem.2747AbstractUnderstanding the behaviour of flexible metal–organic frameworks (MOFs)—porous crystalline materials that undergo a structural change upon exposure to an external stimulus—underpins their design as responsive materials for specific applications, such as gas separation, molecular sensing, catalysis and drug delivery. Reversible transformations of a MOF between open- and closed-pore forms—a behaviour known as ‘breathing’—typically occur through well-defined crystallographic transitions. By contrast, continuous breathing is rare, and detailed characterization has remained very limited. Here we report a continuous-breathing mechanism that was studied by single-crystal diffraction in a MOF with a diamondoid network, (Me2NH2)[In(ABDC)2] (ABDC, 2-aminobenzene-1,4-dicarboxylate). Desolvation of the MOF in two different solvents leads to two polymorphic activated forms with very different pore openings, markedly different gas-adsorption capacities and different CO2 versus CH4 selectivities. Partial desolvation introduces a gating pressure associated with CO2 adsorption, which shows that the framework can also undergo a combination of stepped and continuous breathing. Proposed role of guest–framework interactions in the solvent-dependent continuous-breathing properties of SHF-61. Credit: (c) Nature Chemistry (2017). DOI: 10.1038/nchem.2747 After heating SHF-61-CHCl3 to remove solvent, it exhibited type I adsorption isotherm behavior for N2 and CO2. This was as expected from previous studies. What was new for this study, though, was that CH4 also followed type I adsorption isotherm, but it took much longer for adsorption to occur. This kinetic difference allows for selective adsorption, which has implications for practical uses such as catalysis and separation techniques.Typically studies with MOFs are either all or nothing in the sense that the adsorption measurements are taken after complete desolvation of the MOF to determine total guest uptake. SHF-61 was also studied for gas adsorption as a partially desolvated MOF, which is the first of this kind of study. The partially desolvated SHF-61-DMF showed a stair-step isotherm instead of type I adsorption isotherm typical of an approximately fixed pore size. The mechanism at work here was identified by in situ powder x-ray diffraction and has to do with a sudden opening of the pores at a particular CO2 pressure threshold.Finally, while cation-framework interactions are difficult to study, crystallographic studies show that guest-framework and cation-framework interactions control the breathing mechanism, particularly whether the guest is able to overcome cation-framework interactions. This explains the stair-step adsorption pattern for the partially desolvated MOF. While adsorption of CO2 is at first slow, once the pressure of CO2 is high enough to overcome cation-framework interactions, then the pores open allowing for more CO2 to adsorb.This research demonstrates a unique continuous breathing MOF whose properties have allowed for unprecedented studies in the SHF-61’s mechanism and guest selectivity. This research has implications for molecular sensing for gas separation. Because the authors were able to gain new insights into continuous breathing MOFs, future research may include developing other continuous breathing MOFs.

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. © 2017 Phys.org Explore further (Phys.org)—Researchers from the University of Sheffield report a new continuous-breathing metal-organic framework (MOF), SHF-61, that has two different solvent-specific forms, a narrow-pore structure that is the result of DMF or H2O desolvation and a wide-pore structure that is the result of CHCl3 desolvation. The wide-pore form showed uptake of N2, CO2, and CH4 with selectivity for CO2. They were also able to conduct single-crystal structure analysis of their MOF during breathing motions. Their work appears in Nature Chemistry. “Being modular in construction allows MOFs to be tailored for a wide variety of applications that exploit their molecular-scale porosity. Highly flexible MOFs remain uncommon, but offer the possibility of developing guest-responsive materials. Identifying new flexible MOFs may open many doors for applications, particularly in selective entrapment and release, separation and sensing of molecules,” explains Lee Brammer, who is Professor of Inorganic and Solid State Chemistry at the University of Sheffield. “The flexible behavior of SHF-61 is quite complicated, but what helped in this case is that it proved feasible to study the structural changes in some detail by single-crystal X-ray diffraction.”Breathing MOFs, are metal-organic frameworks whose structure reversibly changes upon some kind of external stimulus. Very few MOFs have been reported to display breathing behavior and of the known MOFs, most undergo some kind of structural change due to a crystal phase transition. This structural change leads to a difference in pore size, which, in turn, allows for the reversible adsorption and desorption of guests. Because these MOFs undergo a phase change, their adsorption profiles (i.e., adsorption isotherms) look like stair steps.What is not common among breathing MOFs is continuous rather than a stair-step adsorption profile. Continuous breathing MOFs, such as MIL-88, have proven difficult to isolate and study. This paper reports single-crystal and powder XRD studies of continuous-breathing MOF SHF-61.SHF-61, or (Me2NH2)[In(ABDC)2], where ABDC is 2-aminobenzene-1,4-dicarboxylate, has an In(III) metal coordinated to carboxylates that serve as hinges for the continuous breathing mechanism. The authors point out that the hinge is from rotation of the ABDC ligands around the O—-O of the carboxylates. This is accompanied by changes in the coordination geometry around In(III). The combination of the two motions enables the continuous breathing.Specifically, In(III) is chelated to four ABDC ligands providing a flattened tetrahedral geometry around the metal center. The resulting anionic framework has diamond-shaped pores, which contain dimethylammonium cations that balance the charge. The pore size is largely dependent on the solvent. Carrington et al. isolated solvated forms of the MOF, SHF-61-DMF and SHF-61-CHCl3, and demonstrated how removal of each solvent affects pore size, and therefore guest uptake, differently. Removal of the more strongly interacting DMF leads to narrowing of the pores whereas removal of the more weakly interacting CHCl3 leaves the pores fully open.

Carbon uptake in Tibetan Plateau soil may offset melting permafrost carbon release

first_img Explore further Citation: Carbon uptake in Tibetan Plateau soil may offset melting permafrost carbon release (2017, May 9) retrieved 18 August 2019 from https://phys.org/news/2017-05-carbon-uptake-tibetan-plateau-soil.html © 2017 Phys.org Anyone paying attention to the science surrounding global warming has heard about the problem of carbon released into the atmosphere due to permafrost melting in colder parts of the planet. Less well known or understood is what happens to the soil above the permafrost. As temperatures rise, soil above the permafrost becomes warmer, offering a haven for new plant growth—such plants have been found to sequester carbon from the air back into the soil. Thus, as more carbon is released from below, more is sequestered from above, but is it possible that new sequestering offsets old release? That is what the researchers with this new effort want to know. To learn more, they studied soil samples taken from multiple sites in the Tibetan Plateau (a large elevated plateau north of the Himalayas) in the early 2000s and compared them with similar samples taken a decade later.The researchers report that the soil samples were taken from depths up to 30 cm (which is above the permafrost line) and found an average accumulation of carbon in the soil to have occurred at a mean rate of 28.0 g cm−2 yr−1, which they concluded was due to accumulation of organic carbon concentrations (material left when plants died). They describe the increase as substantial, and possibly enough to offset carbon released due to permafrost melting. More tests will have to be conducted to determine if there is a true offset, but the study results suggest that climate change models might have to be adjusted if offsetting occurs in regions much farther north. If carbon released by melting permafrost in Russia, Canada and other parts of the world is offset by new plant growth, it is possible that much less carbon will make its way into the atmosphere than has been predicted, resulting in slower than predicted global warming. More information: Jinzhi Ding et al. Decadal soil carbon accumulation across Tibetan permafrost regions, Nature Geoscience (2017). DOI: 10.1038/ngeo2945AbstractPermafrost soils store large amounts of carbon. Warming can result in carbon release from thawing permafrost, but it can also lead to enhanced primary production, which can increase soil carbon stocks. The balance of these fluxes determines the nature of the permafrost feedback to warming. Here we assessed decadal changes in soil organic carbon stocks in the active layer—the uppermost 30 cm—of permafrost soils across Tibetan alpine regions, based on repeated soil carbon measurements in the early 2000s and 2010s at the same sites. We observed an overall accumulation of soil organic carbon irrespective of vegetation type, with a mean rate of 28.0 g C m−2 yr−1 across Tibetan permafrost regions. This soil organic carbon accrual occurred only in the subsurface soil, between depths of 10 and 30 cm, mainly induced by an increase of soil organic carbon concentrations. We conclude that the upper active layer of Tibetan alpine permafrost currently represents a substantial regional soil carbon sink in a warming climate, implying that carbon losses of deeper and older permafrost carbon might be offset by increases in upper-active-layer soil organic carbon stocks, which probably results from enhanced vegetation growth.

Subtle Differences In Brain Cells Hint at Why

first_img by NPR News Jon Hamilton 8.21.19 1:23pm In mice, scientists have used a variety of drugs to treat brain disorders including murine versions of Alzheimer’s disease, depression and schizophrenia. But in people, these same treatments usually fail. And now researchers are beginning to understand why. A detailed comparison of the cell types in mouse and human brain tissue found subtle but important differences that could affect the response to many drugs, a team reports Wednesday in the journal Nature.”If you want to develop a drug that targets a specific receptor in a specific disease, then these differences really matter,” says Christof Koch, an author of the study and chief scientist and president of the Allen Institute for Brain Science in Seattle.One key difference involved genes that cause a cell to respond to the chemical messenger serotonin, says Ed Lein, a study author and investigator at the institute. “They’re expressed in both mouse and human, but they’re not in the same types of cells,” Lein says. As a result, “serotonin would have a very different function when released into the cortex of the two species.”That’s potentially a big deal because antidepressants like Prozac act on the brain’s serotonin system. So testing these drugs on mice could be misleading, Lein says.The comparison was possible because of new technology that allows scientists to quickly identify which of the hundreds of types of brain cells are present in a particular bit of brain tissue.The technology does this by detecting which genes are switched on in each cell. That reveals a genetic signature indicating the type of cell.”In one fell swoop you can get a more or less comprehensive understanding of all of the different types of cells that make up a brain region,” Lein says.This also makes it much easier to compare brain tissue from different species, he says.”We now have access to this fine level of resolution in the human brain and the ability to compare across and see how good a model a mouse or a monkey actually is,” Lein says.The list of cell types also should help researchers see what goes wrong in human brain disorders, Koch says.”A lot of neurological diseases, a lot of psychiatric diseases that we’re suffering from are due to specific defects in particular types of cells,” Koch says.For example, Parkinson’s disease affects brain cells that make a substance called dopamine. And epilepsy involves special cells that tamp down brain activity.Now, researchers have a way to make sure the types of cells involved in a particular disease work the same way in people as in an animal model, Koch says.”The technology finally caught up with what we’ve been needing to do for probably over 40 years,” says Tomasz Nowakowski, an assistant professor of anatomy at the University of California, San Francisco who co-wrote an editorial that accompanied the study. To compare mouse and human brain cells, researchers first analyzed sixteen thousand human brain cells taken from the middle temporal gyrus, a part of the cortex, the brain’s outermost layer. Then they looked at cells taken from the same area of a mouse brain.”In one sense, they are remarkable similar,” Koch says, noting that both mice and people had about 100 different types of cells in this region of the brain.But a close comparison of 75 of these brain cell types revealed small differences.Nowakowsky is especially intrigued by the finding that cells called microglia have a slightly different genetic signature in mice and people.”Those cells are the immune cells of the brain,” he says. “And you might imagine that studies or insights into neuroimmune disorders, for example, might be vastly affected by this difference.”Neuroimmune disorders include multiple sclerosis, systemic lupus, and amyotrophic lateral sclerosis. But there’s growing evidence that microglia also play an important role in Alzheimer’s disease.And that could be one reason experimental Alzheimer’s drugs have helped mice, but not people.Copyright 2019 NPR.

Trauma care centres to come up in major hospitals across Bengal

first_imgKolkata: The state government has chalked out a detailed plan to set up trauma care centres at various hospitals in the state, to ensure quick treatment to accident victims. The government will bear a cost of around Rs 45 crore for the construction of the trauma care centres and for buying equipments.According to initial plans, eight trauma care centres would be constructed in the first phase. The locations would be on or near national and state highways and other important roads. Also Read – Heavy rain hits traffic, flightsIt has been learnt that three trauma care centres would be located at SSKM Hospital, Bardhaman Medical College and Hospital (BMCH) and North Bengal Medical College and Hospital (NBMCH), while three others would be constructed at Kharagpur, Asansol and Islampur. The remaining two will be set up at Singur and Amtala.The critical patients would be admitted in the trauma care centres on an emergency basis. Accident victims or any trauma patient will be kept in the centres, where the patients would be given special care. These trauma care centres will have all the modern facilities to handle such patients. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedThe victims of fire incidents or those seriously injured in accidents, would be taken to the trauma care unit of the hospitals, where they would be given immediate attention. It is important to transfer these patients to a hospital equipped with trauma care facilities. This could save lives of many accident victims in the state, the senior officials of the state Health department said.The construction of the trauma care centre at BMCH has already been done. There will be 25 beds – 10 general, 10 critical care and five step down or high-dependency units (HDU). Accidents victims in the area are often brought to the city’s hospital and it takes a long time to shift a critical patient to the city. Had there been a trauma care unit at BMCH, people meeting with road accidents in the area can be provided treatment faster. The trauma care centre at NBMCH will be made operational soon.According to the Health department sources, the largest trauma care centre is coming up at the SSKM Hospital. It is expected that it can be made operational within September this year. Those coming up at BMCH, NBMCH and Singur will be of level 2 category, while the ones at Kharagpur and Islampur will be of level 3 category. A trauma care centre was inaugurated at RG Kar Medical College and Hospital, a few months ago. It may be mentioned that RG Kar Medical College and Hospital is the first medical college hospital in the state to have a separate dedicated building for trauma care. The eight-storeyed building of the trauma care unit has departments like medicine, neuro-medicine, neuro-surgery, orthopedic and anesthesiology. Patients are availing specialised health care facilities under the same roof. The new building has 150 beds.last_img read more

There will be no place for him/her in the party,” Dutta said, who had been assigned the responsibility to communicate the party’s strong stand in this regard.It has been learnt that Dutta will hold a meeting with representatives from Central Kolkata colleges on Monday, South Kolkata colleges on Tuesday and North Kolkata colleges on Wednesday. Also Read – Naihati: 10 councillors return to TMC from BJPIt may be mentioned that immediately after the CM’s instructions, Kolkata Police on Staurday posted a message on their Facebook page, inviting complaints against people who are demanding money to ensure admission to colleges. It has been learnt that the Chief Minister became furious after reports of students asking for money from freshers to get them admitted in different colleges surfaced in the media.Acting on two complaints, Kolkata Police have already arrested four students, for allegedly extorting money to arrange seats in colleges. Senior police officials are expected to visit some colleges in the city, to ensure smooth admission procedures on Monday. Extra police force will be deployed outside colleges where admissions are going on. Outsiders will not be allowed inside the college premises and only merit should be the criterion for admission.Kolkata Police has posted on Facebook, asking people to email or WhatsApp complaints about extortion related to college admissions.It may be mentioned that in the core committee meeting held at Netaji Indoor Stadium recently, Mamata Banerjee had categorically said that no money should be taken from students on the pretext of providing admissions in colleges and stern actions would be taken against those involved in the matter.The Bidhannagar City Police, on its Facebook and Twitter page, has put up an email id: bdncitypolice@gmmail.com and a WhatsApp number: 9051518444, on which a person can register his/her complaint if there is a demand for money for admission.last_img read more

With no word yet from producers Tollywood imbroglio continues

first_imgKolkata: The stalemate in the shooting of television serials in Tollywood continues as the artistes and technicians are yet to arrive at a negotiation with the producers.The ceasework is the result of a demand by the Artistes’ Forum to regularise pay. The talks between it and the Welfare Association of Television Producers (WATP) are yet to yield results.In a Press release issued on Tuesday by the Federation of Cine Technicians and Workers of Eastern India, signed by senior artistes like Soumitra Chatterjee, its president, Prosenjit Chatterjee, its working president and Arindam Ganguly, general secretary, the artistes have agreed to join work the moment WATP agrees to implement the MoU signed between the producers and the artistes. Also Read – Rain batters Kolkata, cripples normal lifeThe future of nearly 10,000 artistes and technicians has become uncertain because of the stalemate. The artistes have also agreed to sit with the producers.Actor Prosenjit Chatterjee told newsmen that the Artistes’ Forum did not wish to disrupt shooting schedules of TV serials, but the July 8 agreement between the Television Producers’ body should be respected and artistes should be paid regularly.While the agreement between producers and the forum had stipulated that the artistes should get their salaries within the 15th day of the next month, many producers did not honour it and did not arrange the payment overdue to the artistes, Chatterjee maintained. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedHe said in the given situation, it is not possible to resume work unless the producers pay the arrears. Chatterjee made it clear though that he was only referring to a section of producers and not all. The ceasework has been disrupting the overall shooting schedules.Forum general secretary and actor Arindam Ganguly said the July 8 agreement had also specified that any artiste working for more than 10 hours should be paid on an hourly basis after the expiry of the scheduled time. That too had not been honoured by a section of producers.He said the state government is aware of the situation. “Minister Aroop Biswas has been updated of the developments at the meeting and he is trying to arrive at a solution,” he added. Meanwhile, there was no shooting during the day in all the eight studios located across different areas of South Kolkata, due to the ceasework.last_img read more

Pigeons quicker in multitasking than humans

first_imgLondon: Despite their small brains, pigeons are capable of switching between two tasks as quickly as humans – and even quicker in certain situations, new research has found. The researchers believe that the cause of the slight multitasking advantage in birds is their higher neuronal density.For the study, published in the journal Current Biology, the researchers performed the same behavioural experiments to test birds and humans. “For a long time, scientists used to believe the mammalian cerebral cortex to be the anatomical cause of cognitive ability; it is made up of six cortical layers,” said Sara Letzner from Ruhr-Universitat Bochum in Germany. Also Read – Add new books to your shelfIn birds, however, such a structure does not exist. “That means the structure of the mammalian cortex cannot be decisive for complex cognitive functions such as multitasking,” Letzner said.The brain pallium of birds does not have any layers comparable to those in the human cortex, but its neurons are more densely packed than in the cerebral cortex in humans.Pigeons have six times as many nerve cells as humans per cubic millimetre of brain.Consequently, the average distance between two neurons in pigeons is fifty per cent shorter than in humans. Also Read – Over 2 hours screen time daily will make your kids impulsiveAs the speed at which nerve cell signals are transmitted is the same in both birds and mammals, researchers had assumed that information is processed more quickly in avian brains than in mammalian brains.They tested this hypothesis using a multitasking exercise that was performed by humans and pigeons. In the experiment, both the human and the avian participants had to stop a task in progress and switch over to an alternative task as quickly as possible. “Researchers in the field of cognitive neuroscience have been wondering for a long time how it was possible that some birds, such as crows or parrots, are smart enough to rival chimpanzees in terms of cognitive abilities, despite their small brains and their lack of a cortex,” Letzner said.

The name of any political party does not feature on it. If the name of one party is written then it should have been so for other parties as well. It seems that a political party is trying to use technology with an evil intention. We have urged the Commission to take immediate action so that such things are not reflected during the elections,” Chatterjee said. Barrackpore, along with six other Lok Sabha constituencies namely Bongaon, Howrah, Uluberia, Sreerampore, Hooghly and Arambagh goes to polls on May 6, the fifth phase of the ongoing seven phase elections. TMC district president, North 24-Parganas, Jyotipriya Mallick said: “We are witnessing strange things during the elections this year. How can the name of a political party be written under the symbol? The act is illegal and BJP has done this with malafide intentions. They have realised that they will be defeated and so they are doing such things out of desperation.” TMC has also pointed out in its complaint that similar things had also occurred during the mock poll at Raiganj, where the elections have already been held. A senior official of the CEO’s office said that they have forwarded the report of the District Magistrate in this regard to the Election Commission of India for necessary action.last_img read more

Being bullied at workplace can change behaviour for worse

first_imgIf you are bullied at the workplace, it may lead to counterproductive behaviour besides harming your health, warn researchers. The study showed that in some cases this is characterised by a lack of problem-solving and high avoidance coping strategies like drinking alcohol when having a problem and experiencing very frequent negative emotions. “Overall, our results show the need to consider not only exposure to and types of bullying but also their associated consequences,” said Roberta Fida, Professor at the University of East Anglia in England. Also Read – Add new books to your shelf”In particular, the findings highlight that victimisation is associated not only with health problems but also with a greater likelihood of not behaving in line with the expected social and organisational norms,” Fida added. Bullying is one of the major occupational stresses for employees and the effects can compromise their development and health, as well as interfere with the achievement of both personal and professional goals. In the recently published study, the researchers identified different configurations of victims by considering not only exposure to and types of bullying, but also health problems and bad behaviour. Also Read – Over 2 hours screen time daily will make your kids impulsiveThe researchers asked more than 1000 Italian employees about their experiences of workplace bullying, counterproductive behaviour and health symptoms. They were also asked about their coping strategies, negative emotions experienced at work and moral disengagement. “The greater the intensity of bullying and the more the exposure to different types of bullying, the higher the likelihood of engaging in counterproductive workplace behaviour,” said study lead author Fida. “In addition, it is essential to also promote behavioural regulation strategies to reduce moral disengagement, as well as negative behaviour, such as drinking more alcohol.”last_img read more

Conquistador Anchor Found Could be Clue to Cortés Lost Fleet

first_imgIn 2017 an ambitious search was launched for the lost fleet of Hernán Cortés, the conquistador who invaded Mexico in the 16th century. The ships were believed to lie at the bottom of the Gulf of Mexico, containing treasures stolen from the Aztecs.According to National Geographic, an international team of underwater archaeologists in December 2018 found an iron anchor “consistent with the type carried by European ships in the early 16th century… It was discovered off the coast of Villa Rica de la Vera Cruz, a site some 50 miles north of modern Veracruz, where Cortés founded a settlement in 1519.”Hernán Cortés (1485-1547)The anchor “provides the first compelling clue to the location of the wrecked vessels.”Some accounts suggest that Cortés burned his ships to prevent his men from attempting to flee. But Cortés wrote in a letter to Holy Roman Emperor Charles V that rather than burn them, he sank, or “scuttled,” the fleet off the coast of Veracruz.Engraving showing Hernán Cortés scuttling his own fleet off the coast of Veracruz in order to eliminate the possibility of retreat in July 1519.Last year the Sub-Directorate of Underwater Archaeology at Mexico’s National Institute of Anthropology and History announced that it planned to dredge the shores where Cortés landed in order to recover the ships, the Mexican newspaper La Crónica de Hoy reported.The project was led by Pilar Luna, former head of the Sub-Directorate of Underwater Archaeology. They said they planned to see how many of the dozen Spanish ships remained in the Gulf of Mexico where they were left 500 years ago.A scuba diver looks at a huge anchor.The expedition was also prompted by the enthusiasm of treasure hunters, who pressured the Mexican government for permission to explore the cargo of the lost ships.Several of the ships were believed to lie on the sea bed in the Gulf of Mexico, where Cortés supposedly abandoned them, even though none were ever spotted during underwater exploration.If the ships and their contents were in well-preserved condition, they could reveal crucial details about Cortés’ mission and the long voyage to Central America. Relatively little is known about the ships.Scuba diver taking photos“The arrival of Cortés and his conquest of Mexico changed the course of history,” said archaeologist Christopher Horrell, a National Geographic grantee and research fellow at Texas State University who serves as the project’s co-director, in an interview. “These ships set into motion a series of events that changed the fates of the New and Old Worlds. Finding them would be an incredible discovery.”Born in Medellín, Spain, around 1485, Cortés first served as a soldier in an expedition of Cuba led by Diego Velázquez in 1511. He ignored orders and journeyed to Mexico with about 500 men and 11 ships in 1519, setting his sights on overthrowing ruler Montezuma II in the Aztec capital of Tenochitilán.The Aztecs drove the Spanish from Tenochitilán, but Cortés returned to defeat the natives and take the city in 1521.The Conquest of TenochtitlanCortés became allies with some of the native peoples he encountered, but he definitely used deadly force to conquer  Mexico. He fought Tlaxacan and Cholula warriors and then was determined to take the Aztec empire. He marched to Tenochitilán, the Aztec capital and home to ruler Montezuma II. Cortés took Montezuma hostage and his soldiers raided the city.Cortés left the city after learning that Spanish troops were coming to arrest him for disobeying orders. He spent much of his later years seeking recognition for his achievements and support from the Spanish royals.“The conquest was a very traumatic episode in our history that sparks the imagination of most Mexicans,” said Roberto Junco Sanchez, deputy director of underwater archaeology for Mexico’s National Institute of Anthropology and History (INAH) and a co-director of the research project, to National Geographic.Read another story from us: The Amazing Survival Story of the Last Aztec EmpressNext year Mexico will begin to observe events around the 500th anniversary of Cortés’ arrival and conquest.last_img read more

This App Will Make Your Next Virtual Meeting Awesome

first_imgJanuary 5, 2015 3 min read LAS VEGAS — One new video conferencing app is looking to change how you have virtual meetings. Called Personify, the computer and mobile app transforms your average run-of-the-mill video call into an immersive 3-D experience that feels more like an in-person meeting than a conversation with your computer screen.Previously able to just overlay a single person onto a presentation for a one-on-one conversation, the app is today launching new video conferencing features at the Consumer Electronics Show in Las Vegas. Related: 6 Ways to Manage a Virtual Work ForceThe big difference between Personify and competitors like Skype and Google Hangouts is where and how the people you’re chatting with are displayed on the screen. Using a 3-D camera (you’ll need to snag one of those to use the app) and Intel’s RealSense, Personify captures a 3-D image of let’s say developer Bob whom you’re working with across the country.When you chat, the app applies a virtual green screen of sorts (the thing the weather man stands in front of) to the background behind Bob and replaces it with your desktop.  Instead of showing up in a window, Bob will be at the bottom of your computer screen, just like he’s sitting across from you. Any other people you bring into the conversation will be placed beside Bob at the bottom of the page, giving the feel of a roundtable discussion.Related: For More Productive Meetings, Throw Out Your Conference TableWhile the experience can make your average work meeting a bit more natural, the real win with the app comes when you need to work on something with the people you’re chatting with on Personify.  Since everyone is at the bottom of the page, the rest of the screen is open for you to do other things.  For instance, you could use the app while playing a collaborative game with a friend, or watching movie with mom. Unlike some other solutions, there’s a balance between the people you’re chatting with and what you’re doing on your desktop.Videos can also be shared live or recorded and shared later on. That way someone can see your face while watching a recorded video of your pitch presentation or you could have your child chat with grandma about her latest trip to Disney World while virtually showing off pictures. Pretty neat.Eager to give it a try? You can check out Personify for yourself from the company’s website.Related: The Biggest Do’s and Don’ts of Video Conferencing  Opinions expressed by Entrepreneur contributors are their own.

Court Cops Cant Force You to Unlock a Phone With Biometrics

first_img Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goals Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right. January 15, 2019 2 min read If a police officer or federal investigator wants to get into your smartphone, they can no longer use your eyes, face, or fingerprint to force you to unlock it.A federal judge in Northern California has ruled that compelling a device unlock using biometric data is a violation of Fifth Amendment rights against self-incrimination. Cops are already barred from asking suspects to unlock their devices with a passcode, thanks to a Florida appeals court decision this past October. With this decision, biometric login mechanisms are afforded the same protection.In her decision, Judge Kandis Westmore said that fingerprints and face scans such as Face ID on iOS devices are not the same as physical evidence, and that even with a warrant, the government has no right to force suspects to incriminate themselves.”If a person cannot be compelled to provide a passcode because it is a testimonial communication, a person cannot be compelled to provide one’s finger, thumb, iris, face, or other biometric feature to unlock that same device,” she wrote.The case hinged on Judge Westmore denying a warrant to police officers investigating an alleged extortion crime in Oakland, California, where the suspects used Facebook Messenger to threaten the release of a compromising video. She said officers had probable cause to search the suspects’ property, but not to unlock any devices or compel suspects to do so.Apple and other device makers have pushed back against forced device unlocks in many forms for years. The warrant denial, and the precedent it sets for protected biometric data, is a significant decision for digital privacy as well as search and seizure law in the connected devices era.
