Electricity Producing Bacteria

In the quest for finding the most economical means to produce countless watts of power, science has been spending billions of dollars. Turns out it isn’t just human beings that are able to harness electricity but researchers claim that certain microbes are also capable of these rare abilities. Picture this, transferring electrons from a molecule to another is essential for all kinds of organisms because this needs to be exercised in order to produce energy, which is imperative for their survival.

For bacteria living in extreme conditions, finding alternatives for breathing in an oxygen deprived environment requires them to be creatively adaptive. Such microbes exist in various places. As fascinating as it would appear they also live in the ‘Human Gut’. This is how these microbes were forced to breathe in a uniquely creative way by pushing out electrons and as a byproduct, producing electricity.

Let us understand how the engineers, researchers, and scientists are thinking of harnessing the electrical power produced by such bacteria.

Bacteria Producing Electricity – Testing

Research has been going on to figure out ways to harness and develop such microbial power plants that are expected to purify water from the sewage, run fuel cells and other constructive uses.  But here’s the challenge, these microbe cells are much smaller than the conventional mammalian cells scientists have been dealing with and growing them in laboratories is extremely difficult.

The MIT engineers have been able to develop a microfluidic technique. This microfluidic technique enables quick processing of such small bacterial samples and analyzes their specific property. These specific properties, called the Polarizability, determine the highest correlation of electricity production by that particular species of bacteria. Polarizability can gauge the electrochemical activity of the bacteria compared to other techniques.

According to MIT’s associate professor of mechanical engineering, Cullen Buie, the current work being done on the bacteria portends that there is a broad range of such electricity-producing bacteria. Thus a special tool for probing such organisms have now become much more important than they were assumed to be earlier. The reason being, after all the research and experiments carried out, they have come to the conclusion that it is not just the job of a handful of microbes, and more species need to be tested.

Research Results

The study concludes that the higher the polarizability of a bacteria, the higher the rate of electricity produced. We can expect the researchers to start their bacteria search for the strongest candidate that will be able to produce large amounts of power soon. If the analysis made on the bacteria’s polarization turns out as expected then it won’t be wrong to say that this technique will be very useful in accessing electricity-producing bacteria.

Chinese Moon Base

The idea of life in space is very intriguing; numerous movies and TV series fictionalized this concept and had a fair amount of success. Though this notion is not limited to fiction anymore; the possibility of life in space is actually being considered.

While you’re reading this very sentence, a Chinese rover is exploring the far side of the Moon. The fact that no other country has attempted to land on the far side of the moon makes it particularly interesting. Though this mission is full of technical challenges, China is ambitious to create history. As a matter of fact, there has been an official announcement made about the country’s space program stating that China is looking to launch three more lunar missions, which will serve as a ground for their Chinese Moon base.

The reason why no one has made an effort to land on the far side of the moon is mainly due to the multitude of challenges and difficulties in the communicational channels. However, achieving this feat will provide substantial payoffs in terms of scientific research, particularly due to the fact that it will block the stray radio signals from Earth. This will provide an unparalleled view of the radio universe.

Lunar Palace – Virtual base

China is resolute on the plan to set up a lunar base, which is evident with its persistent efforts to ensure the success of this project. To reduce the potential risk of failure and ensure that their astronauts are able to endure the rough condition on the moon, they have set up a Lunar Palace, a virtual base on Earth.

The Lunar Palace is equipped with two plant modules where astronauts grow and harvest food. It also contains a 42 square meter area living cabin with a common room, four sleeping cubicles, a bathroom, a waste management area, and believe it or not, a specific room for growing animals.

The primary objective of this experiment is to see and understand more about how Bio regenerative Life Support Systems (BLSS) function over an extended period of time, particularly in outer space. When considering sustainability of life in the lunar environment, it is crucial that humans, plants, animals, and microorganisms are able to co-exist together without creating obstacles.

Expected Timeline

It is not possible to predict a timeline for the Chinese Moon Base due to the involvement of several factors which could serve as a bottleneck to the entire project. However, there are systematic steps being laid down in order to expedite the process. Firstly, China’s space program will send the Chang’e-5 lander to the moon.  The readings and results collected from Chang’e-5, supplemented by three follow-up assignments will enable them to solidify plans to set up a base. Moreover, they are attempting to print 3D habitable structures using the lunar soil to increase their understanding of the lunar environment.

Another thing to consider is the Long March 9 rocket, which is under development and might be ready to fly by 2028 or 2030. It is bigger than the size of Apollo Lunar module, the rocket that carried astronauts to the moon half a century ago. With these developments, we cannot eliminate the possibility that China will have its own people on the moon by 2030s, which will put them well ahead in the competition from the likes of NASA and ESA.

Surgical Advances

Luckily, due to the advancement of technology and scientific research, our methods of medical treatment is now proving to be revolutionary. Here is how modern surgical advances are predicted to take place in the future-starting now.

Surgery Bots?

Breakthroughs are being made left, right, and centre in the world of science. From autonomous killer robots to sending space crafts on mars, technology is helping us find solutions to issues and questions people have had for centuries. And now in the world of medicine, a report by England’s Royal College of Surgeons may have made traditional surgery obsolete. In the groundbreaking report, the surgeons have highlighted the ways evolving technologies, such as new vaccines, surgical robots, and artificial intelligence will be used in shaping the future of medicine. The predictions say that these technologies will take over in the next two decades.

No Need For Surgery?

Modern surgery and medicines have allowed some operations to become less invasive and more precise. The surgeons’ report is taking modern medicine a step further by making most surgical operations obsolete.

The future of medicine also takes advantage of stem cells. The report by England’s Royal College of Surgeons explains that regenerative medications and stem cell treatments could be used to treat heart conditions and circumvent the need for open heart surgery. The report also predicts that stem cell treatments could possibly be used for the treatment of neurodegenerative diseases such as Alzheimer’s.

What This Report Entails

Overall, less invasive procedures result in safer procedures. Safer procedures mean less room for error and more efficient surgery, reducing recovery time. It’s a great accomplishment for the medical sector and may seriously help to improve the lives of those struggling with life threatening illnesses.

Laser Cannon

The arms race may be escalating quite quickly and intensely, after the public acknowledgment that Russia has developed missiles and laser weapons that are ready for service, Russia posted a video in July 2018 which showcased a laser death weapon, and they have recently announced that it has officially entered service. Here is all you need to know about the Peresvet Combat Laser System, which is essentially a laser cannon, and how Russia plans on using it.

The Peresvet Combat Laser

Just recently, Russia announced that the Peresvet Combat Laser System has officially entered service and now has been permanently installed. The inspiration for the name Peresvet comes from the ancient Russian monk warrior named Alexander Peresvet. The video that Russia released back in July, which openly shows the unveiling of the laser, is said to be able to obliterate targets in a fraction of a second. Not much else is known about the laser cannon itself and thus, many people have speculated that it will not be used to kill people, but will actually be used for defence against enemy missiles and airplanes. It definitely looks like it is straight out of a movie though.

A Boastful Putin

Vladimir Putin, the President of Russia has been boasting about this laser cannon/death ray by saying, “Russia’s capacities for defending itself have multiplied.” Putin also boasted about the fact that laser weaponry, “is not just a concept or a plan any more. It is not even in the early production stages. Since last year, our troops have been armed with laser weapons.” He also taunted those against Russia in the arms race that, “We are one step ahead of our rivals,”

Is This The Start Of A Whole New Arms Race?

The implications of this cannon are far more deadly than they might seem. The death machine of which we do not even know the full details of will probably be used for more than just defence. The US is now threatening to pull out of the INF treaty as they claim the development of this laser cannon violates the treaty. However, Russia is retaliating and saying they are following all the conditions specified in the treaty. Putin also showed his concern over the fact that the New START pact between the US and Russia will expire in 2021 and that the US is not keen on discussing the future of the pact.

Real or Fake?

Some have even speculated that this laser cannon is not all that it is hyped up to be. The speculations stem from the fact that the laser cannon was announced during a press conference that was also hosting the launch of many other overly-hyped weapons. People also claim that Russia has previously lied or not been completely honest about their new technologies and that there is no evidence whether the cannon actually works as it claims to (since the video never showed it firing).

All we can hope for is that Russia and America stay true to their agreement and talk it out before deciding to fire on each other.

Home Surveillance

If you think that scientific exploration has covered every aspect of our lives, well think again! Traditional home surveillance methods normally include locks and maybe an alarm system and cameras. Well, Alex Pachikov, ex Evernote executive and CEO of Sunflower Labs seems to think there is quite a lot of room for improvement. Here is how the Sunflower system may be innovating the way we secure our homes.

Cute Name, Disturbing Game?

The name for the company (Sunflower Labs) and its products (the Sunflower sensors and the Bee drones) are all inspired by things we find in the garden. That may seem very cute, but their functions, which are autonomous, may be disturbing for some. With all the privacy scandals against big companies such as Apple, Facebook, and Google, some may think it is not wise to leave our home surveillance to autonomous machines.

The Sunflower sensors that are camouflaged as garden lights are built to detect vibrations near the home and can differentiate between the whir of your coffee machine, pets, and footsteps. The ‘Sunflowers’ around all corners of the ground outside the home so that it can create maps and also sense the people and objects present within the space. The kicker, however, is that the sunflower system includes a drone, named the ‘Bee,’ which flies out from its station called the ‘Hive,’ all by itself. The Bee leaves the Hive and flies around the home if any suspicious activity has been discovered, using the Sunflowers that have been installed to establish a pathway. Moreover, it uses the sensors and built-in cameras in order to avoid any object that may come in the way during flight.  It streams live footage on your tablet or phone, which is automatically saved on the cloud system later on. It can be manually deployed if the homeowner gets an alert from the Sunflower sensors and lands. The homeowner will have to press the relevant button in the Sunflower app, signalling the drone to dock all by itself to the Hive, which also works as a wireless charger.

Who Can Use This?

It is evident that such a sophisticated home surveillance product would not be affordable to the general public. The CEO says that the Sunflower Labs will soon be offering this device on a subscription base to the wealthy homeowners residing in the suburbs of California. It may become affordable for the general public if the costs get subsidized, but for now only the elite can afford this system. This arrangement works for Sunflower Labs, as the Federal Aviation Administration does not allow drones to be flown out in public. Thus, lawn owners in suburban areas are the suitable target audience for this system.

Can It Be Trusted?

With the recent allegations of smart home devices listening to and recording conversations without obtaining permission, hacking of several accounts, and the leak of private information, it may not be the best option to trust technology to maintain our privacy.

Self-Driving Deliveries

Just a decade ago, we never could have imagined the existence of technologically driven services available to us today like Spotify, Uber, Snapchat, Virtual Reality, Instagram, Airbnb and even Google Chrome. And now, they are a part of our everyday life. Being able to easily order clothes, taxis and food using a smartphone has become the norm, and people are spending less time at shopping centres and grocery stores. But for those who really do not want any human interaction, even when receiving their order, are now in luck. Self-driving delivery services are becoming a reality!

What Are Self-Driving Delivery Services And When Will They Be Available?

Many companies have been working on autonomous vehicles for quite a while now. In recent years, certain companies have been working hard to make self-driving delivery services a norm. From Nuro that already have a working model, to Ford that has teamed up with Walmart and Postmates to deliver everyday groceries to customers at affordable prices. Self-delivery services are deliveries that are made using autonomous vehicles. No drivers, just the goods you want. Ford has been testing using a research vehicle that mimics autonomous vehicles to gather more info about customer preferences. Ford has stated that commercial autonomous vehicles will be available by 2021.

The Benefits Offered By Autonomous Vehicles

Besides being able to conveniently get goods delivered to your home, workplace or sent as a gift to someone without the hassles of dealing with a delivery driver, or having to shop for it yourself, there are many potential benefits that autonomous vehicles offer. One such benefit is reduced costs for stores, as they will not have to hire drivers. Another benefit is that it could be potentially safer, as someone who is home alone and is ordering from a store could meet a potential predator when dealing with delivery personnel. Also, for people who have severe social anxiety, they will not have to contact a delivery driver when ordering groceries, or have to go out to do their grocery shopping either. The same goes for those who are suffering from a contagious illness. Autonomous vehicles would lead to less humans driving on the roads, potentially reducing the risk of injury and death due to accidents.

The Potential Dangers Posed By Autonomous Vehicles

Besides the ‘technology becoming smart enough to come alive and kill people’ scenario from terminator coming true, there are some realistic dangers that autonomous vehicles pose. Firstly, they could lead to unemployment with stores opting for self-deliveries rather than hiring deliverymen. It may also lead to excessive social anxiety and laziness, and people will really not need to leave their homes in order to get something, but would rather just avail the services of an AV to get the job done.

Self-driving cars have been a popular subject of conversation for many years, but the fact that now companies have already launched, or are ready to launch, autonomous vehicles just tells us how much technology has advanced, and how much we rely on technology to live our life.
