NASA organized a competition to develop astronaut evacuation solutions. Its winner is Dr. Thatcher Cardon, who will get the funds to realize his idea.
NASA engineers working on new space vehicles and space exploration devices can not forget more mundane matters. It is up to them, the question of how to deal with physiological needs, which in space is not an easy matter.
Astronauts in space, like any other human, must expel. And since getting to orbit and mooring to the space station usually takes a bit longer, so you need to create a system that will allow you to safely store your metabolism.
In October last year, NASA organized a competition called Space Poop Challenge to develop a concept of dealing with urine and faeces. The waste management system had to keep them safe for at least 144 hours in the astronauts’ suits, and the author of the best idea could count on a good reward.
Thatcher R. Cardon, Air Force Lieutenant Colonel of Del Rio, Texas, was the author of the most interesting proposal. Cardon works as a family doctor and surgeon, so he used his knowledge and experience to create a project called MESP (MACES Perineal Access & Toileting System). He took 15 thousand dollars for it.
Air-PUSH (Air-Powered Urine and Stool Handling) was developed by a team of physicians from the University of Texas at Austin. The device uses astronaut’s body movements to keep the waste away from his body. This project won $ 10,000. The last place in the competition was taken by London designer Hugo Shelley, who got 5 thousand. Dollars for SWIMSuit. This is a special lingerie that can keep dirt for six days.
NASA engineers will now test all the winning ideas and decide which one will be installed in the new suit.
The US space agency is choosing a landing site for the new Mars 2020 rover that will go to the Red Planet. Three location proposals have been identified for the best.
NASA continues exploration of Mars and in a few years wants to send another rover called Mars 2020, which will explore the planet. The task of the new instrument is to be much more serious as it will have to drill in its surface, exploring the soil and looking for traces of life at a much greater depth.
The Space Agency has not yet chosen the final landing site for the new Jeep, but together with the Californian Monrovia scientists, they have selected three of the best proposals that have the best chance of finding a living there.
Most of the votes were given to thecrater Jezero, which in the past was a lake of comparable size to Lake Tahoe. The river flowed to him, so it could be the perfect place to look for traces of life.
The second proposal is Syrtis, where hot water could circulate beneath the surface, while the third was the Columbia Hills. That’s where the Spirit rover discovered silica rocks that correspond to Earth’s hydrothermal mineral deposits.
Weight is an important parameter in portable equipment, even if it is a projector. SANYO launches the small PLC-XW65 projector weighing 1.6 kg.
The device displays an XGA image (1024 x 768 dots) and measures 265 x 74 x 189 mm. It offers brightness of2500 ANSI lumens as well as great freedom of installation. The vertical trapezoid correction function automatically corrects them in +/- 20 degrees.
The projector is characterized by a projection ratio of between 1.33 and 1.62: 1, which is the same as those obtained with a 1.2x wide-angle zoom lens. Thus, even in a small room, you can get a large diagonal image.
The owner of the PLC-XW65 does not have to be careful not to let him down for a moment. The PIN lock function allows you to limit the use of the projector to authorized persons only.
This miniature projector is also economical in operation. Long life of the bulb (3500 hours of operation in economy mode or 2000 hours of normal operation) allows for a long time not to worry about the need to replace it. The low power consumption is also a source of savings: in normal operation, the device only charges 225 watts, and the economical mode reduces power consumption to 185 W. When the projector is not in use and in standby mode, it consumes only 3.8 watts .
The manufacturer also includes a bag, infrared remote control (with batteries), instruction manual, power cord, 15-pin D-Sub cable and lens cover at the price of the projector.
Social media can be a real mine of knowledge on a variety of topics. Perhaps soon will also be used by law enforcement agencies to prevent crime. This is at least the intention of a new project implemented by Cardiff University researchers.
They work on a special tool that will allow the police to scan social media, helping identify the focal areas that can lead to hate crimes. The Justice Department-funded project will be based on a special algorithm that scans Twitter by searching for hate speech in specific geographic areas of the United States. The purpose of the algorithm will be to find patterns between the hate speech present in the network and the brutal crime committed in the streets.
If the system is successful, the police will be able to anticipate the outbreaks of violent crimes and hate crimes that could be caused by triggers, such as the death of Keith Lamont Scott, shot dead several days ago by the police.
The learning machine learning system has less offensive words related to hate speech, which are not always directly linked to racism. This will identify cyberbullying in any form.
Los Angeles will experiment with the new system and its task is to allow the police to intervene before the situation gets hot. Of course, before the algorithm becomes fully useful, much work is still left to its creators. You have to learn to identify the phrase with regard to the context, and create a map of the area of the city in which the most common crimes are committed.
Work on the system is planned for at least three years.
Sharp has presented the world to the successor of the Aquos Crystal, which many consumers have admired for their unique design. The new model is even more modern and nicer, and thanks to the exceptionally thin frame surrounding the display, it feels like it occupies almost the entire front of the device.
Smartphone makers have so far failed to fully realize the concept of frameless design, as the concept affected front sensors and a camera that forced the frame to have a clear frame to accommodate.
Sharp, however, believed that the idea could be realized, and the example was the Aquos Crystal, where the 5-inch display occupied 78.5 percent of the front panel. The company’s accomplishments, however, were not enough and now its successor was presented. The Aquos Crystal 2 also has a thinner frame, which makes its 5.2-inch screen about 80 percent of its front panel surface.
The dimensions of the new smartphone are 136 x 71 x 11 mm and the weight is 154 grams. This is not a top-of-the-line model, so its 5.2-inch display has a resolution of just 720p, which for today’s standards is very small.
The processor is also not a speed demon, as it has a quad-core Snapdragon 400, which is supported by 2GB of RAM and 16GB of usable memory, which can be expanded with a microSD card. The manufacturer has also equipped the device with an 8 megapixel camera and a 2 megapixel front camera as well as a 2030 mAh battery and the internet connects to the LTE standard. The operating system is Android 5.0 Lollopop.
Lockheed Martin engineers on behalf of the US Army are working on a mobile laser system. 60 kW power weapon will be a defensive weapon that protects against rockets.
Military technology will soon enter the next evolutionary sphere and soon, instead of traditional missiles and rockets, combat will be carried out using laser weapons. Such weapons are not yet common, but military engineers have been working on weapons projects for years. One of them is occupied by Lockheed Martin people.
The company has announced the successful completion of the new 60kW mobile laser power test. The company has already created similar armaments before, but it has so far been able to boast half the power. The achievement is undoubtedly very important, because during the tests we managed to fire a 58 kW radius, thus beating a record in the category of lasers of this type. This was accomplished by combining the radii of several lasers into one strong beam.
Torrent sites are one of the most popular sites on the Internet, but their owners have not been able to translate it into real money until recently. Now, however, this has changed and since some of them have dealt with the distribution of malware, the profits of their owners have risen up.
Experts from Digital Citizens Alliance and RiskIQ warn that torrent sites, so readily visited by Internet users, can be a big threat to them. Research has shown that users are 28 times more likely to be infected with malware compared to regular sites. What’s more, the attacks are silent and the user does not even know that malware has been installed on his computer, as it does not require any action from him.
And what does this malicious code do? Approximately 45 percent of the cases install adware that displays ads on victims’ computers. Approximately 10 percent of the cases are unwanted toolbars, while 9 percent are botnet clients who take control of the hardware.
Many malware, however, takes over our personal data, which can then be sold online. It also collects credit card numbers and even steals money directly from our accounts, such as changing your account number when making a transfer. Ransomware is also a big threat blocking important files and demanding ransom.
Distribution of malware can be extremely profitable for webmasters. According to the Digital Citizens Alliance, their total revenue last year was nearly 64 million euros, and the owners of each site, according to the number of visitors, rake from 182 to 4500 euros a day.
Anyone who spends many hours every day in front of a computer knows how important his work tools are – desk and chair, whose ergonomics determine the comfort of work. There are already many models of desks that are designed to make it more comfortable, but on their particular stand is a desk called Station.
Station is basically not a desk, but more like a dental chair that was designed by Altwork engineers so that many hours of work did not adversely affect our muscles and spine. As you can see in the attached picture, the employee is sitting on a special folding chair and his head is supported by a comfortable headrest.
In front of him there is a tabletop on which you can put the keyboard and mouse, and a bit further there is a monitor. There is also an extra, movable arm on which we can put, and next to are convenient shelves for holding other trinkets.
The station weighs 95 kg without a monitor and can be set in four basic positions. So it will serve as a standard sitting desk, desk stand or workstation for several people. And if we want to relieve our muscles, then they can be set in such a way that we are lying down.

By the end of June this year, energy prices on the stock market approached those of August 11, 2015, when energy supplies were reduced to large companies, as a result of which many businesses had to curb production or shut down office buildings. This situation can also happen again this year and touch both businessmen and residents. The first heat wave brought temperatures in excess of 35 degrees Celsius, which is just the beginning of the holiday.
Heat can be cumbersome, especially if we do not spend their vacation on water. Air-conditioned offices may offer tempting alternatives, but prolonged adverse weather conditions and associated network overload may lead to unpredictable power outages. For this reason, storms, and more specifically the associated discharges, are an additional threat to unprotected equipment respectively.
– Electricity is essential today in almost every field of life. We have more and more electronic devices and we need more and more energy for their service. High temperatures are not conducive to them. Imagine what would happen if the city was regularly cut off from the heat supply because of the heat, and all the daily necessities denied us obedience? Are we waiting for closed office buildings, deserted cities and night life? Fortunately, this is an extreme scenario, as the latest technology allows you to adapt your infrastructure to regular heat. More and more buildings are being built that intelligently manage energy and will eventually allow it to be used more efficiently and in smaller quantities. “We are now able to minimize the unpleasant effects of unexpected power outages in our homes and businesses using guaranteed power solutions,” said Jacek Parys, Sales Executive, IT Business, Schneider Electric. UPS devices, the so-called. Uninterruptible power supplies, in the event of a power failure, support current in connected devices, whether they are computers, electric blinds, gateways, monitoring systems or widely used radio and home appliances.
