Funnels breakdown inside the anthill

Funnels breakdown inside the anthill

This new defensive behavior , reported in the journal Social Insects , was discovered while scientists initially assumed funnels be a way to fight against the unwelcome visitors. However, during their tests, all the ants introduced to these inputs have proved potentially able to reach the interior of the colony.

Two other functions of these funnels were also evaluated. http://enjoycoloring.com/ If they help to divert rainwater to ensure the impermeability of the nest, the authors believe that simple tubes have the same efficiency.

However, these constructions flared six times better aerate the heart of the colony where ants produce a dangerous amount of carbon dioxide . "Gas exchange can explain the development of recurrent funnel several entries lines ants, in particular among species cliff " , is it concluded in the article.

Malagidris Sofina is an ant confined to a small area of ​​forest

When invader risk in one of these nests, a soldier grabbed him and jumps to evict him. After having released the ground, the bodyguard back to the colony healthy and sound ( see video ).

For researchers, it is a defense tactic original and very effective. To test it, they brought in such chimneys 78 individuals of a rival nest or belonging to another species . In 33 cases of intrusion, soldiers fought with the intruders, especially the potential predators from their congeners. http://enjoycoloring.com/ In half the cases, they have approached the rim of the funnel and have trained with them overboard.

"I know of no other ground dwelling ants jumping as this species " says Stephen Yanoviak, ant specialist at the University of Louisville in Kentucky, United States. If ants tree are known to jump from branch to branch or floor, he adds, is to escape predators.

When junk is captured, the soldier ant Malagidris Sofina , Madagascar, do not hesitate to drop him down from his nest to the extract. Once on the ground, it goes back to the colony. http://enjoycoloring.com/ This radical defense strategy is new to science because ants tend to use the jump to move or to escape a predator.

This value of the LSF is calculated from the reflectance measurements retrieved from the infrared heat (typically between 3 and 5 microns and between 8 and 14 microns).

Reading these cards is very simple. Enjoy Coloring The red and blue dots are temperature anomalies observed in relation to an average taken to refer, in this case the same week between 2005 and 2013, with many spread across the globe highlights the very unusual nature of that period, Straddling the months of July and August.

Red dots indicate areas that were up to 10 degrees Celsius above the average, while blue have below average reference temperatures. As for the gray areas, it is either the oceans, bodies of water or absence of data due, for example, an overly dense cloud cover.

In France, one can say that the beginning of the summer was dreary, marked by record rainfall and a lack of sunshine. Elsewhere, the weather has also made his own example, record heat recorded in Eastern Europe or steep temperature drops in some regions of the United States or Russia.

This map of Europe speaks for itself.  Clearly areas where it was very hot (Eastern Europe, Sweden ...) or abnormally low (Southern Europe, the heart of Russia) is seen.  © NASA MODIS Science Team

The Nasa has published global maps of temperature anomalies for July 2014 (and the week of July 27 to August 3, 2014). They were made ​​from data acquired by the MODIS instrument satellite Aqua. www.enjoycoloring.com This is a Moderate Resolution Imaging Spectroradiometer to measure cloud properties and the flow of radiant energy. Observing the entire planet every one to two days, it is able to deliver daily maps of surface temperature (LST). The latter is also called skin temperature as it reflects, to some extent, how a hot surface would feel to the touch.

These filter almost perfectly optimize their anatomical surface

For scientists, the anatomy of these animals pluribranche maximizes the body surface and is consistent with the osmotrophie, power fashion of filter feed , from substances dissolved in the seawater.

Because Rangéomorphes were radically different from all known forms of life, scientists knew little about how these creatures lived, were breeding or foraged.  We now know that these primitive animals were well adapted to their environment.  © Verisimilus, Wikimedia Commons, cc by sa 2.5

These filter almost perfectly optimize their anatomical surface

"Geometrically speaking, they were well organized to do it, capable of creating the largest possible area of absorption in any space they occupied, " says Jennifer Hoyal Cuthill from the University of Cambridge, UK , lead author of the article published in the journal Proceedings of the National Academy of Sciences .

This result is consistent with the ecological conditions of the time: the competitors and predators were absent and the ocean environment rich in microscopic nutrients. Enjoycoloring.com "Oceans of Ediacaran more like a coarse soup, full of nutrients such as carbon organic, while nowadays, food particles in suspension are quickly collected by a myriad of animals, " says co-author Simon Conway Morris, a paleontologist at the University of Cambridge study.

With the explosion of multicellular life in the Cambrian period , the Rangéomorphes became extinct, there are about 540 million years. The supposed causes are competing for nutrients with other agencies, predation and depletion of specific resources they needed.

Fractal creatures filtered the Precambrian oceans

Fractal creatures filtered the Precambrian oceans

The comprehensive study of the anatomical organization of Rangéomorphes can lift a mystery about these strange marine living organisms on Earth, there are 575 million years. Branches that are composed and which duplicate according to a fractal model light on their feeding mode.

If they were all organized on the same basis of fractal branches, as shown in these 3D reconstructions, the Rangéomorphes grew vertically from 10 to 200 cm.  coloring book pages Horizontal spongy forms of these animals could also cover 58 square meters of ocean surface.  © University of Cambridge

We knew that was not Rangéomorphes plant nor fungus sailors, but many animals belonging to the phylum of Petalonamae . For about 40 million years ago, during the Ediacaran , they dominated the world's oceans, living attached to a substrate at different depths. Before they occur, life was microscopic.

However, we disregarded their mode of nutrition . From specimens fossils , researchers have managed to recreate the 3D morphology of 11 taxa and measure their functional properties.

Three main types, vertical and horizontal, have been highlighted: tall, thin, shaped fir other side flourished in the way of trees lapsed and a shape resembling a sponge deployed on the seabed. These plans fractal organization that are unlike any other known reinforce the idea that they have their clade, that is to say, their own group comprising the ancestors and all descendants.

the theory of Riemann

Located at the intersection of differential geometry, topology and complex analysis work Maryam Mirzakhani fall at first pure mathematics but we know that they often, sometimes decades or even centuries Later, unexpected implications in the natural sciences.

As the theory of Riemann surfaces occupies a very important position within the framework of the theory of superstrings, and even in different areas of physics, perhaps we can expect a few surprises. adults coloring pages Especially since some of the results obtained by the mathematician are already in connection with the string theory and the work of two other winners of the Fields Medal on the subject, Edward Witten and Maxim Kontsevich .

Presumably this first award of a Fields Medal to a woman used to reduce the gap between the number of male and female mathematicians as hope that the researcher said in a news release from the University of Stanford: 'c It is a great honor and I would be happy if it encourages young scientists and mathematicians "women , adding , "I am convinced that many more women will this type of reward in the coming years" .

Fertile complex surfaces in applications

Fortunately, this situation did not last long and in the years that followed, it turned out to be a prodigy in mathematics. It will stall twice the gold medal at the International Mathematical Olympiad in 1994 in Hong Kong in 1995, in Toronto with the highest score possible.

Fertile complex surfaces in applications

The work of the mathematician deal with the geometry and topology of the so-called Riemann surfaces , surfaces like a sphere or a pretzel whose description is closely related to the functions whose variables are numbers complex (for those who want to know more, the mathematician Étienne Ghys, CNRS research director at the Ecole Normale Supérieure de Lyon, recently devoted an entire article to Maryam Mirzakhani the must in the CNRS Images Math ).

The researcher was particularly interested in surfaces with a hyperbolic metric. coloring pages for boys The surface of a saddle, with its negative curvature different from that of a sphere which is positive, has a hyperbolic metric. With his colleague, mathematician Alex Eskin has established remarkable bridges between the theory of Riemann surfaces and the theory of dynamical systems. As with the work of Yakov Sinai on ergodic theory, the two researchers used the behavior of the trajectories of balls on pool tables of various shapes to explore the behavior of some of these dynamic systems.

Maryam Mirzakhani talks about his path from his childhood

The famous diary Quanta Magazine of Simons Foudation also devotes an entire article to the researcher. Pure product of the ultra-elitist education system in Iran, the mathematician does not least his doctorate at Harvard University in the United States under the direction of another winner of the Fields Medal, Curtis McMullen . coloring pages for adults After his graduation in 2004, she spent several years at Princeton before moving to Stanford where she is a professor since 2008 can find more details on its trajectory in a interview she granted and in the video below --Bra which supplements.

Born in 1977 in Tehran, she was part of a generation she described as lucky, that is, those whose adolescence was held after the Iran-Iraq war. Initially, she did not intend to become a mathematician and was interested in all the books that could fall into his hands. Leaving primary school, she was for a time an unpleasant experience with mathematics. One of his teachers even thought she was not particularly good, which was a source of discouragement for her, temporarily breaking his nascent interest in mathematics.

Android 4.4 KitKat leak shows tweaked but familiar Android interface

Will Google announce KitKat and the Nexus 5 next week? Maybe. Is the latest leak enough to hold you over? Probably not, but here it is anyway. This is purported to be Android 4.4 running on the upcoming Nexus 5, and if it seems to look a lot like Jelly Bean, that’s because it does.

There are a few tweaks: a transparent notification bar, a tweaked app drawer showing five rows of four apps each over your phone’s background instead of black, and the ability to access Google Now by swiping left past the leftmost home screen. The Nexus 5 also reportedly features the same “OK, Google Now” voice commands as the Moto X.

There are likely to be plenty of other changes — some on the surface, some under it — that will be revealed when Google unveils the latest update.  It’s Android 4.4 version number, however, seems to be more and more fitting. Despite getting a new codename with KitKat, the build will share a lot in common with Jelly Bean.

Rumors point to Google unveiling KitKat and the Nexus 5 next week, possibly on October 15th. Keep it tuned here for all of the latest developments.

Greed for Glory: War Strategy for Android Review

Greed for Glory: War Strategy enters the freemium field with exciting but strangely run-of-the-mill gameplay. It's similar to titles like Battle Dragons and Clash of Clans: the only real difference being a new setting and art style. But despite lacking any sort of innovation, PerBlue's medieval-themed building/combat sim will keep you strangely captivated for weeks on end. Just go easy on the diamonds, okay?

More at DroidStars.com

Greed for Glory puts you at the helm of a small village looking to become more than a collection of wooden huts. Build new structures as you mine iron and gold, collecting as much currency as you can so you can raise a massive army of archers, knights, and wizards. With all of those trained soldiers milling around, might as well head out and attack nearby villages, right? Increase your fame (and your loot) by sacking other towns, slowly expanding and upgrading your base to accommodate your newfound power and glory.

Amazon Kindle Fire HD refresh sports new look, same specs

Amazon has just unleashed two new Android tablets to add to its Kindle Fire HD line, so it’s kind of expected that all eyes would be on the new Kindle Fire HDX devices. But if the high specs and relatively higher prices aren’t your kind of thing, then maybe Amazon’s second take on the Kindle Fire HD might make you feel less left out.

The Kindle Fire HD, itself an evolution of the original Kindle Fire, is already a year old. Everyone has been expecting Amazon to bring out new tablets, which it did today, but it seems that the retailer giant has other plans for the old 7-inch device. Instead of completely replacing it with the new Kindle Fire HDX 7, Amazon has decided to instead repackage the original Kindle Fire HD with a new look, both inside and outside.

T-Mobile Moto X getting software update to improve camera quality

The Moto X is an excellent phone, but if there is was anything holding it back, it’s the camera quality. The perception from myself and many other reviewers is that it’s a software issue, and it looks like we were right. An update is now ready to roll and T-Mobile’s Moto X is going to be the first to get it. The changelog is as follows:

Designing a custom Moto X with a 4-year old using Motomaker

Most of the tech bloggers were given an opportunity yesterday to customize a Moto X using a Beta version of Motomaker. We already did a thorough hands on at the Motorola event a couple of weeks ago so I didn’t take this opportunity to give you another boring hands on. I decided to bring my 4-year old son along for the ride and let him customize it the way he wanted. This video isn’t going to be as professional as my other videos, but it is an example of someone diving right in without playing with it for an hour before turning on the camera. We just opened the site, went through our selections, and order it. We didn’t get into the engravings or the wallpapers, but you can see more about that stuff in our previous hands on.

Motorola Skip for Moto X formally announced, includes three Skip Dots and is free with custom Moto X purchases

Last night, a new accessory for the Moto X called Motorola Skip showed up and vanished just as quickly. We already had an idea that it was designed to clip to your pants to unlock your Moto X easier, at least for those that use a security PIN or pattern lock. This is the case, but Motorola just formally introduced it and gave us a little more information.

If you remember, back in May at D11, Regina Dugan showed off some futuristic ways people will be able to use to authenticate their devices. The Motorola Skip isn’t that futuristic, but it is an example of some of the early progress that Motorola is making. Even though it is something that every smartphone/tablet owner should do, often times people don’t set a security lock screen since it’s such a pain to unlock the device just to read a quick email. Motorola Skip was designed to allow Moto X owners to implement this security, but still be able to unlock their device with ease.

How to use VPN on Android

VPN services

You can also subscribe to VPN services that will allow you to browse securely and/or anonymously through public Wi-Fi hotspots from your phone for a monthly fee. You can even get an IP address that’s out of a different country, so that you can access online TV services and other services that are restricted to users from that particular area. 

Built-in Android VPN client

Android phones generally include a built-in VPN client, which you’ll find in the Settings | Wireless & networks menu. It’s labeled VPN settings: Set up and manage Virtual Private Networks (VPNs), as shown in Figure 1. The phone used for the screenshots is an HTC Thunderbolt running Android 2.2.1 (Froyo). However, Android has included VPN support since version 1.6 (Donut).
