Behavioural cloning (Imitation learning) has been there in human race since ages. For learning various skills, we try to imitate the actions of the experts in that field. To become better sportsperson in a particular game, new entrants watch the videos of Olympic winners and try to imitate their actions. Similarly, children follow the actions of their parents while watching them throughout the early stages of their life.

Reinforcement learning is based on the philosophy of evaluating all the state space possibilities in context of agent and reward paradigm. While it has shown tremendous potential in solving many problems, but it has its own limitations in complex environments. Many times, it is not possible to define the state and reward due to the fluidity of the situation and you are not able to divide the activity into discrete steps or states.

Recent experiments by researchers have shown that if we can combine behavioural cloning with reinforcement learning mechanism, then it gives more promising outcomes. Behavioural cloning is kind of a supervised learning technique where you are pre-labelling some of the action sequence as best practices. In this the system will have a faster learning curve.

There are tremendous applications which will be suitable for imitation learning algorithms.

Improving our work force: We can train our AI system on the videos of best employees in your work force and can then benchmark others based on that. For example, in armed forces, if soldiers are supposed to respond in a certain way in specific situations, then the system will be trained on the best soldiers responding to those situations. These videos frames for best soldiers actions can be labelled for different activities. Rewards and penalties can be described based on these actions. Now the videos of any other soldier can be taken responding to those situations and AI can be applied to determine the final performance score. This kind of evaluation is applicable in any domain where some physical activity/skill is involved in completing the task. It will help you to improve your work force and eventually increase your productivity. Even if you want to automate your workplace then Robots can be trained using imitation learning. Instead of making the Robots to learn from zero knowledge base, they can learn from the best practitioners of the field using behavioural cloning.

Imitation Learning: As the Robots will become the norm in day-to-day life, it will be essential to localize them as per the cultural, ethical, and social requirements of the community. In such cases, imitation learning will be very useful. These machines can be augmented using the videos of local representatives on various customs, salutations, routine conversations, gestures etc and the robots will learn to respond accordingly in addition to their core task for which they have been built.

Physically Challenged People can operate devices: Equipment like TV, Washing Machine, Kitchen Equipment, Gardening equipment and others can be easily trained to be used by physically challenged people based on specific actions through voice, hand gestures, eye gestures etc depending upon the abilities of that person.

Autonomous cars: Similarly Autonomous cars can be trained using behavioural cloning of expert drivers. Many companies are already at advance stages of research on this to be used for their vehicles in specific terrains.

Eventually, the punchline is that if we have an example of some best action practices being done by animals, birds, humans, machines or other mechanisms, these actions can be recorded and labelled.

Then the AI models can be trained using the combination of Imitation learning and Reinforcement learning for the AI systems to improve their performance/accuracy.

Behavioural cloning will push the limits of reinforcement learning - The Times of India Blog

When hives of the African lowland honeybee (Apis mellifera scutella) collapse, they do so because of an invisible inner threat: the growing, immortal clone army of a rival bee subspecies.

That army is possible because the female workers of the rival subspecies the South African Cape honeybee (Apis mellifera capensis) can create perfect copies of themselves, with one individual found to have done so millions of times in the past three decades. With this perpetual-cloning ability, the Cape honeybees sneak into the hives of their lowland honeybee rivals and churn out copy after copy (no need for a queen). Even worse, these clones are freeloaders, refusing to do any work.

Now, a new study has revealed the genetic foundations of the strange and formidable adaptation. Unlike most animals, and even their own queen, the female workers do not reshuffle the DNA of the eggs they lay. This enables the workers to consistently recreate a perfect copy of themselves a clone each time they reproduce. According to the researchers, the sidestepping of this DNA-reshuffling process is unlike anything they've ever seen.

"It's incredible. It's also incredibly dysfunctional," lead author Benjamin Oldroyd, a professor of behavioral genetics at the University of Sydney, told Live Science, referring to the fact that reshuffling is normally required to hold chromosomes together during the egg-making process. "Yet, somehow they've managed to do it [still lay eggs]. It's insane; I've not heard of anything like this before, anywhere."

Honeybee workers and other social insects have the ability to reproduce via a form of asexual reproduction called thelytokous parthenogenesis, in which females produce female offspring from unfertilized eggs. Each time she creates offspring, the single-parent worker bee will replicate the chromosomes she received from her parents (a queen and a male drone) into four. Next, she takes the genetic material from all four chromosomes, reshuffles it and creates four chromosomes with that mixed-up DNA through a process called recombination. This reshuffling guarantees that, even with just one parent, future offspring will be genetically distinct.

However, as only two chromosomes out of the four are picked and no new genetic material is introduced by a sexual partner, this leads to an average loss of one-third of genetic diversity every time the shuffling is performed, or every generation, Oldroyd said. After just a few generations of parthenogenetic reproduction, the accumulated loss of genetic material leads to levels of genetic diversity that are low enough to be lethal.

Most social insects, therefore, rely on a queen that reproduces sexually on their behalf. In return, the genetically diverse workers maintain the health of the colony and protect the brood of their closely related siblings and cousins.

"It's like in a human society, we have this tension between what's good for the individual and what's good for society, and we come up with all of these social norms that allow us to function," Oldroyd said. "In honeybee societies, one of the things that evolved to suppress selfish behavior is [that] the workers generally can't lay eggs."

This is mostly true of the Cape honeybee, which on the whole abides by the usual rules of social insect reproduction, according to Oldroyd. But Cape honeybee workers have a genetic mutation that enables them to lay eggs parthenogenetically with all of the genetic material from the four chromosomes (so they dont throw out any of those chromosomes somehow). With that ability, they can prevent the immediate loss of genetic diversity caused by the reshuffling process. This allows them to clone themselves whenever they like for decades, even if cloning in the much longer term leads to a population that, on the whole, has no genetic diversity.

This cloning superpower places colonies on a much finer balancing point between individualism and sociality. And if they tip over, they may be at risk of extinction, according to the researchers.

To understand how the clones can create millions of copies of themselves and yet remain functional, Oldroyd and his team compared the genomes of Cape honeybee workers with those of their queen and her offspring.

After forcing the Cape queen to reproduce asexually by fitting her with surgical tape that prevented her from mating, the team examined certain DNA sequences of both the Cape queen and the 25 larvae she produced. Then, they did the same for four Cape honeybee workers and their 63 larvae.

The team discovered that the asexually reproduced offspring of the queen had levels of recombination (DNA mixing) 100 times greater than the genetically identical cloned offspring of the workers a finding that suggests the Cape worker bees have evolved a mutation that prevents recombination. Without the risk of a one-third loss of genetic material caused by the asexual reshuffling process, the workers are free to continually create perfect copies of themselves.

The workers ability to clone at will places their colonies in a much more precarious position, especially once the queen leaves or dies and the old social order collapses. Instead of expending energy to get the colony back on its feet, workers will dedicate themselves to selfish schemes such as finding ways to place their clones into positions of power.

"If you take the queen away, for instance, instead of raising a new queen like other bee species might, these bees will just start laying eggs themselves," Oldroyd said. "There are also cells, called queen cells, where the queen lays the eggs containing future queens. It's perfectly possible for a worker to fly in from another colony, or one of the existing workers in that colony to come and replace that queen egg with one of their clone eggs. That way, they can be genetically reincarnated as a queen."

But one lineage of Cape bee workers has taken this socially parasitic behavior even further, to the point where they no longer need a queen, and they solely exist by taking over the hives of the African lowland honeybee. Members belonging to a single branch of rogue clone Cape bee workers sneak into African lowland honeybee hives, which are commonly used for agricultural purposes, and lay as many eggs as they can, which the African lowland bees mistake for their own and rear.

The parasitic clone Cape bee larvae are in on this ruse, even sending signals to their unfortunate hosts to feed them as much as possible. This cuckoo-like behavior allows them to grow their bodies and their ovaries almost to the size of a queen's.

"The Cape bee clones don't do any work inside those hives because they've become reproductive," Oldroyd said. "They just strut around with this attitude like, 'Yeah, you're going to work for me.' It very quickly leads to the collapse of the hive. As individuals, these clones are quite dysfunctional, so you'd expect them to peter out. But they're a lot like the cells in a tumor in this regard it doesn't matter if every clone is healthy, so long as enough of them are around to exploit the host."

The Cape bee workers that take part in this parasitic behavior are the genetically identical descendants of a single worker that lived in 1990, according to Oldroyd. This single lineage of clones is responsible for the collapse of 10% of African lowland honeybee colonies every year.

Now that the researchers have a handle on how the workers can accomplish their bizarre cloning trick, they want to figure out how queens can switch on the gene that enables recombination and how the workers can switch it off. They also want to investigate the African lowland hives parasitized by Cape bee workers, to figure out what triggers the hive collapse.

The researchers published their findings June 9 in the journal Proceedings of the Royal Society B.

Single bee is making an immortal clone army thanks to a genetic fluke - Livescience.com

Over the past three decades, a single individual bee has successfully created millions of clones of herself thanks to hitting a bizarre genetic jackpot.

This growing army of clones poses a serious risk to the hives of the African lowland honey bee, 10% of which are collapsing every year, as the colonies become filled with clones that consume their resources refuse to share in the work.

Scientists have described the bee's mechanism of reproduction as "incredible" and have traced the lineage back to a single worker bee that lived in 1990, according to research published in the journal Proceedings of the Royal Society B.

It was previously known that the subspecies of Cape honeybee was capable of creating a perfect copy of itself, but this poses serious issues for genetic diversity.

Many forms of social insects are able to reproduce asexually, creating female offspring from unfertilised eggs using two of four chromosomes replicated from their parents.

These chromosomes are reshuffled in the process, meaning that the next generation will be genetically distinct - but there is a limit to how many generations can be reproduced in this way.

Because only two chromosomes are passed on and no new genetic material can be introduced to the next generation, every time a worker bee reproduces in this way the species loses about a third of its genetic material.

This is why most social insects depend on a queen for their reproduction, retaining the genetic diversity of the colony which is constituted of insects that are related.

But a new study has discovered that mutation in Cape honey bee workers is allowing them to pass on all of the genetic information from the four chromosomes from their parents, enabling the subspecies to clone itself for decades - although at the cost of genetic diversity.

Speaking to Live Science, the lead author of the study, Professor Benjamin Oldroyd, described the findings as "incredible" and also "incredibly dysfunctional". "Somehow they've managed to do it. It's insane, I've not heard of anything like this before, anywhere."

It is not clear what the end will be for the clone army, but Professor Oldroyd suggested it is likely to be an evolutionary dead-end, not just because the cloning system suppresses genetic changes but also as the self-interest of the clones might hamper their ability to respond to a catastrophe.

"If you take the queen away, for instance, instead of raising a new queen like other bee species might, these bees will just start laying eggs themselves," Professor Oldroyd told Live Science.

"There are also cells, called queen cells, where the queen lays the eggs containing future queens. It's perfectly possible for a worker to fly in from another colony, or one of the existing workers in that colony to come and replace that queen egg with one of their clone eggs. That way, they can be genetically reincarnated as a queen."

Because the Cape honey bee is reproductive, it does not contribute to any work inside of the hives it infests.

"They just strut around with this attitude like, 'Yeah, you're going to work for me.' It very quickly leads to the collapse of the hive," Professor Oldroyd added.

"As individuals, these clones are quite dysfunctional, so you'd expect them to peter out. But they're a lot like the cells in a tumour in this regard - it doesn't matter if every clone is healthy, so long as enough of them are around to exploit the host."

"It's incredible. It's also incredibly dysfunctional."Perfect Clones

In news thats emerged straight from your nightmares, scientists have discovered a subspecies of bees that can create perfect clones of itself and uses those clones to invade rival bee hives.

Scientists discovered that a female South African Cape honeybee doesnt reshuffle its DNA when it lays an egg, according to Live Science. This allows it to create perfect clones of itself every time it reproduces, rendering it virtually immortal. Scientists even discovered one bee in this subspecies that has produced millions of clones over the past three decades alone.

Researchers studying this unsettling phenomenon published a paper of their findings in the journal Proceedings of the Royal Society B.

Its incredible. Its also incredibly dysfunctional, said Benjamin Oldroyd, lead author of the study and a professor of behavioral genetics at the University of Sydney, to Live Science.

Oldroyd is right to be surprised. Asexual reproduction isnt unusual when it comes to insects. When it happens though, the parents DNA is typically mixed up during a process called recombination. So even though the offspring has just one parent, their genetic makeup is different.

But thats not the case with the South African Cape honeybee, which seems to just be creating a perfect copy of its DNA every time it reproduces.

The bees actually pose a bit of a problem for its own colony and rival bee hives. Thats because in typical colonies, only the queen is able to reproduce. If the worker bees are able to create offspring, the hives become dysfunctional.

Eventually the workers just sort of hang around laying eggs not doing any work, Oldroyd said to New Scientist. The colony dies, and [the cloning workers] spread to the next colony.

According to Oldroyd, this phenomena kills off roughly 10 percent of South African bee colonies each year and is like a transmissible social cancer.

A Single Bee Has Created an Immortal Army with Millions of Clones - Futurism

A little while ago in the Krakoan X-Men comic book Hellions, when Madelyne Pryor died, we discovered a new policy on the island of Krakoa. As part of the new X-Men status, mutants who die can be resurrected courtesy of Cerebro and The Five. But one of their rules is that they will not resurrect duplicates whether genetic, parallel dimensional versions of time travelling alternates.

Art from Hellions #4.We were first made aware of the policy from Krakoan's Quiet Council, after the death of Madelyne Pryor.

Time for Scott, her ex-husband to give the news her ex-boyfriend, his brother Alex

Got to lobe those Krakoan family trees. It didn't go down well.

In Cable, starring the son of Madelyne Pryor (told you), he has own issues, tracking down Stryfe, the clone of his future self who he killed, who is stealing mutant babies.

Which brought back memories of Inferno, when Madelyne Pryor and mutant babies were used by Mister Sinister, and some senior demons to bring Hell to Manhattan.

All the time that Sinister has been disobeying the No More Clones rule with himself and we know he has other secret cloning-related plans with chimera as well.

And as a result of these rules, neither Madelyne Pryor or her child, the adult Cable, were allowed to be brought back from the dead with the rest, even as Teen Cable tries to make the latter happen.

X-Factor were tasked with establishing Proof of Death before reviving someone, so to avoid having multiple versions of the same person and soul -running around. Though we still reckon that happened with Laura Kinney and Old Woman Wolverine in X-Men. Did Laura Kinnery really die in the Vault? Was the younger version of herself resurrected without her Vault memories and now a member of the new X-Men team, at some point have to face a version of herself that has lasted centuries?

But there still seems to be some wiggle room. In Wolverine #12, The Five resurrect Logan even though he hasn't died. Just a version of him without a soul or a brain. And naturally Gabby, herself a clone of Laura Kinney, has some concerns in New Mutants as well.

With a little more pushback than Havok was able to give.

There's also concerns in Cable regarding Stryfe's plans being similar to those that started Inferno, and Majik checks there too.

While in the most recent New Mutants, we discovered that Gabby had, herself, mysteriously died on the island of Krakoa, at the end of the Hellfire Gala.

With the question as to would she be revived under Krakoan laws against reviving clones? And could the revival of Laura Kinney as Wolverine, when Old Woman Wolverine inevitably turns up, underline the issues here? In today's Cable #12 however, Teen Cable makes the case

finally gets his way. And Old Man Cable is revived.

With a couple of mentions for everyone watching Loki at the moment and wondering about the TVA.

Also The Summers War againsgt Stryfe? And that it all may be heading to an early Inferno. As Stryfe has been doing his own cloning, far away from Krakoa.

We presumed that the new Inferno from Jonathan Hickman and Valerio Schiti would be a very different ebast to the original Inferno, more about Mystique burning down Krakoa. Could there also be a more.. traditional bent to it as well?

Cable, Krakoan Clones And Setting Up An Early Inferno? (Spoilers) - Bleeding Cool News

In the episode, The Bad Batch finally solves one of its most intriguing mysteries: the origin of Omega, a young, blond clone who obviously doesnt look like the rest of her people (not to mention that shes a girl, while all of the other clones are male). But her appearance isnt the only special thing about her. We also learn that shes an unmodified clone created from Jango Fetts DNA just like Boba Fett! Even her name ties into Jango Fetts clone son, who was originally designated the code name Alpha before the bounty hunter named him. Yes, Omega is sort of Boba Fetts sisterfrom a certain point of view.

Its Tech who reveals the truth to his companions after studying Omegas DNA more closely: I further analyzed Omegas genetic profile and discovered she has pure, first-generation DNA, he says in the episode. All clones were created from a host named Jango Fett. While our genetic structure was modified for growth and acceleration and obedience, Omega is a pure genetic replication.

Therefore, since the Kaminoans have lost track of Boba in the years since the Clone Wars started, Omega is the only remaining source of Jangos original DNA, the key to creating more Gen 1 clones and restoring the Clone Army to its glory days.

Earlier episodes allude to the fact that so many generations of clones have been created from Fetts DNA at this point that the original genetic strain has been stretched too thin, resulting in mutations in the line as opposed to 1:1 copies of the Gen 1 clones. The rogue-ish Bad Batch, for example, are the result of these mutations.

Recovering Omegas DNA would allow the Kaminoans to restore its line of Jango Fett clones to their purest form, which Lama Su believes will put his cloning facility back in the Empires good graces. He hires bounty hunter Cad Bane to recover the asset and bring her back to Kamino so that he can extract a sample of her DNA and terminate her.

But not all Kaminoans agree that this is the right course of action. Chief medical scientist Nala Se, one of the key engineers of the clone army, has hatched her own plan to save Omega, whom she feels protective of despite her beliefs in The Clone Wars that clones are disposable. It seems that Nala Se has had a change of heart.

If you're still using a traditional, spinning hard disk on your PC, you're missing out. Swapping it out for a solid-state drive (SSD) is one of the best upgrades you can make in terms of speeding up your computer. It'll boot faster, programs will launch instantly, and games won't take so long to load anymore.

You could reinstall Windows from scratch, and in some situations, that may be preferablebut with the right tools, you can get up and running much quicker by copying your entire drive over to the new SSD.

Obviously, in order to upgrade to an SSD, you'll need to, well, buy an SSD. We have some recommendations, but if you're on a budget, we have a separate list of cheap SSDs as well. Make sure to buy the right form factor for your computer (some laptops will use 2.5-inch drives, while others might use M.2 or mSATA drives), and get one big enough to fit all your data. If you have a 500GB hard drive now, you should probably spring for a similarly sized SSD (or larger, to accommodate future data).

The only exception is if you're on a desktop computer and have room for multiple hard drives. In that case, you could store Windows and your programs on the SSD while putting your music, movies, and other media on a second, larger hard diskthough this can be a bit more complicated, as we'll discuss below.

During this process, you'll need both your SSD and your old hard drive connected to your computer at the same time. If you're using a laptop with only one hard drive slot, that means you'll need an external adapter, dock, or enclosure that can connect your bare SSD to your computer over USB. (Again, desktop users may not need this if they have room for two drives inside their PCyou can just install it internally alongside your old hard drive.)

There are many different drive-cloning tools on the market, and unfortunately there's no free, one-size-fits-all option. If your drive manufacturer offers a migration program, that might be your best bet. For example, if you bought a Samsung SSD, we recommend downloading Samsung Data Migration and following the instructions in the user guide. Western Digital and SanDisk users can use WD's version of Acronis True Image to copy their data using these instructions.

For this guide, we'll be using Macrium Reflectit's a free drive-cloning tool that works with any brand of hard drive and SSD. Just download the installer for the free home version and run through the wizard to get it up and running on your PC. It's available to anyone, no matter what brand drive you have, so if your drive manufacturer doesn't offer a migration tool, Macrium Reflect is your next best bet.

Once you've gathered your necessities, it's time to get started.

Before you start messing with drives and formatting partitions, it's absolutely necessary to back up your data first. An accidental click can result in you erasing everything, so do not continue until you've backed it all up.

If you don't have a backup yet, check out our favorite software for the job. Windows also has File History for backing up important documents, and an image file can save your entire system. Copying important data to an external hard drive will also do in a pinch.

If you're upgrading to an SSD that's smaller than your current hard drive, you'll want to take extra care here. This isn't as common as it once was, thanks to bigger, less expensive SSDs, but if that's the case for you, you'll need to delete some files and free up space on your hard drive before cloning it. Otherwise, your data won't fit on the new drive. Once your data is safe and secure, continue to the next step.

Plug your SSD into the SATA-to-USB adapter, then plug that into your computer. If it's a brand-new drive, you probably won't see the drive pop up in File Explorer, but don't worry; it just needs to be initialized first. Open the Start menu and type "partitions" in the search box. Click the Create and format hard disk partitions option, and Disk Management will open. It will prompt you to initialize the drive using either the GPT or MBR partition table.

I'll be using GPT for my SSD, since I have a modern PC with a UEFI firmware. If you have an older PC with a traditional BIOS, you may need to use an MBR partition table. If you aren't sure, look up your specific model of PC or motherboard to see which type of firmware it uses.

If you aren't prompted to initialize the drive, and don't see it in Disk Management, double-check that it's properly connected to your computer, and that the enclosure or dock is powered on (if necessary). See our guide to troubleshooting a hard drive that won't show up for more.

Once the drive has been initialized, you should see the drive show up in the bottom pane of Disk Management as unallocated space. From there, you should be good to go.

Open Macrium Reflect and you should see a list of drives in the main window. Find your current driveit'll list your C: partition with a Windows logoand select it. Click the Clone This Disk button that appears below that drive to start the cloning wizard.

This will bring up a new window where you will choose your destination drivein this case, your empty SSD. If your SSD is the same size as your old drive, make sure the box all the way to the left of your source disk is checked, as shown above, then click Select a Disk to Clone. Choose your SSD from the drop-down list, and click Next.

If your SSD is significantly smaller than your old drive, this may require an extra step. Reflect will attempt to automatically shrink partitions with free space to fit it all on the drive, but in my experience, it doesn't always do this intelligently, and may leave out one of Windows' recovery partitions. If you experience this problem, you can manually drag each partition down to the SSD, and click Cloned Partition Properties on your main C: drive to resize it manually.

If your SSD is larger than your old drive, it may leave some unused space on the drivein which case you'll want to select your main partition, click Cloned Partition Properties, and expand the drive to fill that empty space.

Click Next and you'll be asked if you want to save this backup schedule. You can uncheck that box and click OK to run the backup now, one time. This can take anywhere from a few minutes to a few hours, depending on how large the disks are, so go watch Netflix and come back later.

When its done, you can exit Macrium Reflect. You should see your new SSD in File Explorer, complete with all your data.

Next, shut down your computer. It's time to install that SSD in your machine permanently. If you have a laptop with only one hard drive slot, you'll need to remove your old hard drive and replace it with your SSD. This is a bit different on every laptop.

If you have a desktop PC with more than one hard drive slot, you can leave your old hard drive in as extra storage, and just install your SSD alongside it.

Once you're finished installing the SSD, you'll need to tell your computer to boot from it. (This may not be necessary on laptops with just one drive, but if you experience problems booting, it can help on some PCs.) Turn your computer on and enter its BIOS/UEFI setupthis is a bit different on every PC, but it'll usually say something like "Press DEL to enter setup" on the boot screen, so you'll want to press the corresponding key as it starts up.

From there, look for your BIOS's boot options. These will be in a different spot depending on your computer, but once you find them, select the option to change the boot sequence. Choose your SSD from the list as the first boot drive, then head back to the BIOS's main menu to exit, saving your settings.

Your computer will reboot, and if all went well, it should plop you back into Windows faster than ever before. Open File Explorer and check to confirm that your SSD is, in fact, the C: drive. If everything looks good, you're ready to rock.

If your old drive is still installed, you can erase it and use it to store extra files, or you can disconnect it entirely. Best of all, your computer should feel significantly snappier without having to start from scratch.

Noida: A 45-year-old Bulgarian national was among three people arrested by the Noida police on Sunday for allegedly cloning ATM cards and withdrawing money.

The suspects were identified as Ruslen (the alleged mastermind who is from Bulgaria), and Ravikar and Komal from Bihar. Police said the three were living in a rented accommodation at a highrise in Sector 75. They were nabbed from Sector 18 following a tip-off from an informant.

According to police officials, Ruslen had come to India on May 10, 2019 on a tourist visa and was sent to Tihar jail within a couple of weeks allegedly in connection with a cyber crime. He allegedly met Ravi in jail who was lodged there in connection with a murder case. Ruslen was released on February 1, 2021 after which he had started living in Noida.

He holds a diploma in electronics and is well-versed with cloning technology. He himself prepared the circuits and skimmers, parts for which were ordered from a spy goods website, said additional deputy commissioner of police, zone 1, Kumar Ranvijay Singh.

Police said the group allegedly would install the skimmer devices and mini cameras at unmanned ATM kiosks across the National Capital Region. They would collect the data of users, clone their ATM cards and then withdraw money from their bank accounts.

There are more people associated with the operation, including other foreign nationals, and we are working to trace them. The total amount skimmed by the suspects is being verified through bank account details, though it is suspected to be in lakhs, said a senior police official, on condition of anonymity.

Police recovered 28 cloned cards along with laptops, phones, seven skimmer boards, a camera, card readers, a hard drive, several pen drives, multiple tools and other electronic gadgets. The suspects were produced before a magistrate and later sent to jail.

Foreign national among three held for cloning ATM cards in Noida - Hindustan Times

Hives of the African lowland honeybee (Apis mellifera scutella) collapse because of an unseeable inner threat: the growing, immortal clone army of a rival bee subspecies.

(Photo : Getty Images)

That army is attainable because the South African Cape honeybee (Apis mellifera capensis) - the female workers of the rival subspecies - can make perfect copies of themselves, with one individual discovered to have done this millions of times in the past three decades. With this continual-cloning ability, the Cape honeybees creep into the hives of their lowland honeybee rivals and churn out replica after replica (no need for a queen).

Unfortunately, these clones are freeloaders, refusing to do any work. Now, a new study has disclosed the genetic foundations of the bizarre and formidable adaptation. Different from most animals, and even their own queen, the female workers do not rearrange the DNA of the eggs they lay.

This enables the workers to constantly recreate a perfect replica of themselves - a clone - every time they reproduce. The bypassing of this DNA-reshuffling process is different from anything they've ever seen, according to the researchers.

A professor of behavioral genetics at the University of Sydney, lead author Benjamin Oldroyd told Live Science, "It's incredible. It's also incredibly dysfunctional," making reference to the fact that reshuffling is usually needed to hold chromosomes together during the egg-making process. "Yet, they've managed to still lay eggs somehow. It's insane; I've not heard of anything like this before, anywhere."

Honeybee workers and other social insects are capable of reproducing through a form of asexual reproduction known as thelytokous parthenogenesis, in which females produce female progenies from unfertilized eggs. Every time she creates offspring, the single-parent worker bee will clone the chromosomes she got from her parents (a queen and a male drone) into four.

Next, she takes the genetic material from all four chromosomes, rearrange it and makes four chromosomes with that mixed-up DNA through a process known as recombination. This reshuffling assures that, even with just a single parent, future offspring will be genetically different.

However, as just two chromosomes out of the four are selected and no new genetic material is contributed by a sexual partner, this causes an average loss of one-third of genetic diversity each time the shuffling is performed, or every generation, Oldroyd said.

Following just a few generations of parthenogenetic reproduction, the piled-up loss of genetic material causes levels of genetic diversity that are low enough to be deadly.Most social insects, therefore, depend on a queen that breeds sexually on their behalf.

In return, the genetically diverse workers maintain the health of the colony and safeguard the offspring of their closely related siblings and cousins.

Single Bee Clone Itself Millions of Times Over the Past Three Decades - Nature World News

Scientists have discovered that a subspecies of South African honeybee is comprised of millions of clones from a single honeybee, thanks to a bizarre genetic jackpot.

For over three decades, the growing army of clones has been found to be a serious threat to the hives of the South African honeybee. Sky Newsreported that 10% of hives are collapsing each year due to the colonies being filled with the clones that consume their resources but refuse to share in the work.

A subspecies of South African honeybees can clone themselves and create more bees like them. Genetic analysis reveals that their cloning habit began on a single honeybee in 1990 that clones itself successfully and produces queens that can take over the hive, according to New Scientist.

The process of asexual reproduction or parthenogenesisis common in lower plants or animals, like ants, aphids, wasps, and bees. However, having an offspring that is identical to the parent is uncommon because genetic material is often mixed up in a process called recombination that could result in an offspring with a slightly different genetic makeup.

It was previously known as the subspecies of Cape honeybee (Apis mellifera capensis) that are capable of creating a perfect copy of itself, according to Benjamin Oldroyd of the University of Sydney.

He added that creating clones that are a perfect copy of the parent could be beneficial as asexual reproduction could often be lethal because one-third of the genes become inbred. But since the Cape honeybee workers are a perfect clone, they remain genetically healthy as their mother.

"It's incredible. It's also incredibly dysfunctional," Oldroyd told Live Science,referring to the DNA reshuffling method necessary to hold chromosomes together during the egg-making process of the honeybees that clone themselves. "Yet, somehow they've managed to do it [still lay eggs]. It's insane, I've not heard of anything like this before, anywhere".

The generations of parthenogenic reproduction have accumulated to the loss of genetic material that led to low levels of genetic diversity that are lethal. Most social insects rely on their queen to reproduce, while workers help maintain the colony and protect the brood.

But in the Cape honeybee's case, workers do not work because they can asexually reproduce. Oldroyd said that these bees seemed to develop a dysfunctional attitude that leads to the collapse of the hive. He compared it to cells in a tumor in which it does not matter whether the clones are healthy, as long as there is enough of them to exploit the host.

The single lineage of Cape honeybee workers that take part in this parasitic behavior is responsible for the collapse of 10% of South African honeybee colonies every year.
