In a new report from Nature, a team of scientists have just announced that their latest invention of autonomous nanobots can successfully be deployed within mice as a means of combating and curing cancer.
Using specially programmed DNA strands folded onto themselves, these nanobots seek out cancerous cells within a mouse and inject them with a drug that causes blood clots, cutting off a tumor’s supply of blood and causing it to die off before any harm can be done to the host.
The initial tests for these bots were carried out on mice injected with human breast cancer tissue samples. Within just two days of being injected intravenously with the DNA nanobots, the cancer cells had all begun to die off after the bots successfully located them and started treatment. Additionally, no other parts of the mices’ bodies were seen to have irregular clotting, meaning this treatment would carry little to no risk for patients.
Not only that, when this experiment was replicated with a species of miniature pig, the results turned out to be the same. As there were no signs of clotting in these pigs, it would suggest that even larger creatures would not face unexpected side effects from this cancer treatment as some have feared. The study authors say that they hope to be able to see the same results if they are ever cleared for testing on humans, wishing to implement these nanobots as a human cancer treatment one day.
Compared to other forms of cancer treatment like chemotherapy or invasive surgeries, it’s clear that this nanobot-focused strategy is the way of the future. While many more tests will need to be done before any trials could be conducted on human test subjects, the possibilities are no less impressive. Should these nanobots be approved for treatment strategies after that, they could completely change how we deal with cancer, greatly reducing the mortality rate and level of seriousness associated with the disease.
NASA is looking to the past as it prepares for future space feats. In its quest to reach Mars, the American space agency is considering the use of nuclear energy to power spacecraft, an idea that had been abandoned decades ago.
In a partnership with NASA, the private company Nuclear Energy has been awarded a contract to develop a nuclear reactor and the fuel it will use to power a spacecraft to the red planet. Nuclear engines will have some advantages over conventional rockets, which burn fuel to provide thrust. In addition to being more efficient, nuclear engines will be more compact, which will in turn reduce the size of spacecraft used in lengthy missions. They also offer greater flexibility than conventional rockets, making it easier to alter or abandon a mission if necessary.
Perhaps the most important aspect of nuclear propulsion is its greater power, which will increase the speed of spacecraft and reduce the time needed to reach other planets. Launched in 1975 with conventional rocket technology, the Viking 2 unmanned vehicle took nearly a year to complete its journey to Mars. A manned spacecraft using a nuclear engine might be make able to make the trip in only five months. More about the use of nuclear power in space exploration is available at www.reddit.com/r/technews.
Engines using a combination of nuclear and thermal technology were studied and even tested by the United States over a period of nearly 20 years until the program was cancelled in 1972 due to cost issues. The cost of nuclear engines could be a barrier to future designs, but recent technological advancements could make nuclear energy more practical and less expensive.
Whether or not the United States enters the nuclear space race, other countries are moving ahead with their own plans. A Russian company will soon test a nuclear engine that is being specifically designed to take a spacecraft to Mars. China has its own plans, using nuclear technology to power shuttle-type spacecraft it will be launching in the near future.
Progress insists on pushing out the old to make room for the new. However, it is clear that sometimes doing so leaves us all feeling a little nostalgic for the way things were. At the very least, we like to try to think about some of the pieces of modern technology that are going the way of the dinosaur so to speak. It can help us appreciate that technology for what it was while at the same time looking forward to what will come next.
There are more than a few pieces of modern technology that are very likely to meet their end in the near future. We want to take a look at what a few of those items are today.
CDs- You might have already heard the news that Best Buy is pulling CDs from their store shelves as customers are simply not purchasing them enough anymore. There was once a day when this was the only way that people got new music. With streaming services and digital downloads, listening to music this way has simply become outdated.
Cords- Cords of any kind for electronic devices are on their way out. The technology needed to make things cordless as simply gotten better and better. These days, we do not have as much need for power cords as we once did. It has meant that we can transition to a less corded world in general. So long tangled up messes!
Cable Television- There is just something about those streaming services like Netflix and Hulu that make cable not seem all that important anymore. A lot of people are simply ditching their cable television in favor of the ability to stream what they want when they want it. Thus, cable may be on its way out as well.
These are three of the things that are very likely to meet their end in the near future. Keep an eye out for what replaces them.;
When people are asked what the ideal smartphone is, the common responses that they give is a phone with all screen and no borders. There are no buttons or anything other than a screen. There is good news for those fans. This is very close to becoming a reality. For one thing, there have been smartphones released with a screen that takes up more space than usual. As a matter of fact, the smartphone is almost all screen and no borders. One company that comes to mind is Samsung. They have released the Galaxy S8 with the endless screen. Of course other companies are jumping on the bandwagon with what they can do with their screens.
Given that the smartphone market is heating up, it is important for other smartphone companies to make sure that they are coming up with something that is innovative. While Samsung does have the lions share of the smartphone market along with Apple, there are plenty of other companies that are just competing for a share in the market profits. However, the one who manages to bring forth something very new for the consumer is going to be the one to beat out all of the other competitors.
The edge-less phone is going to be the next step for smartphone technology. This is going to be the one that is going to have people in amazement. When they get to enjoy all of the benefits of a smartphone with a larger screen and no borders, then they are going to be enjoying devices more. Of course there are plenty of other inventions that people can bring forth in order to get themselves ahead of the smartphone market.
The majority of Russian want a separate internet of their own, says a poll conducted by the Russian Public Opinion Research Center.
Nearly 60% of those polled said they would prefer to have their own internet within the BRICS nations.
BRICS is an economic and political entity which includes, Brazil, Russia, India, China and South Africa. These countries represent the most important economic and political partners with the former Soviet Union. Their agreement also includes military cooperation.
By uniting into a separate internet network they would protect their citizens from harmful aspects of the internet hackers and increase the overall security level.
In Russia, cybersecurity is crucial. Almost every day there are hacker attacks on websites of different banks, companies and even government agencies.
In 2016, coordinated hacker attacks caused major corporate websites to offline for several hours costing multinational corporations tens of millions of dollars. The internet is a powerful weapon in the hacker’s hands. According to statistics, 65% of all data is stolen through the internet and cloud services.
In addition, Moscow sees more conflicts in cyberspace with the West after Russia annexed Crimea in early 2014.
The technical coordination of the internet is handled by one company Icann, the Internet Corporation for Assigned Names and Numbers. It is registered in Los Angeles California and the US government participated in its creation giving the U.S.
Some analysts believe that the U.S. was behind the internet outage in North Korea in late 2015. True or not, Russian officials sense that if someone wanted to deny Russia internet access there are technical capabilities to achieve this goal. And this is exactly what the Russian government and their BRICS allies want to avoid.
Scientists have taken a leap forward toward the goal of growing artificial human organ replacements thanks to a new application of 3D printing technology. The new method has successfully created material that is soft and spongy like human brain and lung tissue.
Using a 3D printer, researchers create shapes similar to human organs using a synthetic composite hydrogel. Once these organ “scaffolds” are completed, they are “populated” with living cells which grow on the spongy material to fill out a complete organ.
There’s still a lot of bugs to be worked out of the process, however. For example, developers of the technique have yet to work out a way to prevent underlying layers from collapsing when additional layers are added. Because 3D printers work by spraying on layer after layer, each additional layer puts more pressure on the lower sections.
But there’s considerable reason for optimism. A fix has been developed that involves cooling down the lower layers with a cryogenic freezing technique. This makes them more stable and able to accept additional layers of material. After printing is completed, the frozen layers can be thawed slowly. The key is to maintain the integrity of the shape desired once fully warmed.
So far, brain-shaped 3D-printed organs have been populated with skin cells which are added over a layer of collagen applied to the hydrogel. The method is not yet ready for real brain cells, although smaller brain parts have been successfully populated using genuine neurons. Making a whole brain “scaffold” with the 3D print method has yet to be perfected.
This cutting-edge 3D bioprinting research is being conducted by the Department of Mechanical Engineering at Imperial College London in cooperation with the Tissue Engineering and Biophotonics Division of King’s College London.
It’s unclear when cryogenic bioprinting will be ready for actual human transplant. However, the ability to produce soft-tissue structures with this technique is a significant accomplishment.
Verizon Wireless announced on Monday that it will soon start locking new smartphone purchases made in store or online. This lock would exist for a fixed period of time, during which the user would be unable to insert a new SIM card and activate service through a different cellular carrier.
In recent years, Verizon has sold unlocked smartphones in their retail and online stores. When a customer would buy a new Apple iPhone or Samsung Galaxy, a Verizon SIM card would come pre-installed in the device, but the owner could remove it at any time and activate a new network either in the United States or abroad. Verizon had agreed to follow this process as part of settlement with the FCC, which granted the company access to a block of 4G network space in exchange for not blocking customers from switching networks.
Verizon’s new policy regarding locked phones is expected to go into effect this spring. The company does not believe it contradicts the agreement with the FCC, primarily because the driver of the change is related to theft protection. Verizon believes that by locking all new smartphones after purchase, it will deter criminals from trying to steal the devices.
Verizon has yet to reveal how long the locking policy will apply to new phones. Currently, other major U.S. carriers have similar rules in place. At&T locks smartphones for a minimum of 60 days, while T-Mobile’s wait period is 40 days.
As a result of this announcement from Verizon, more of the network’s customers may choose to shop directly from manufacturers like Apple and Samsung. When a phone is purchased directly from one of those companies’ stores, the device is delivered fully unlocked with no restrictions on what type of SIM card can be activated on it.
