WD showed at Computex drive with SATA Express

Although the prices of SSDs are falling more and more, HDD drives are still irreplaceable for storing more data. That is why many companies are striving to provide the fastest possible transfer and hybrid solutions that incorporate both technologies, which feature new interfaces.

During the Computex fair, Western Digital unveiled a completely new SATA Express drive, based on the same solution used in the WB2 Black, but with a much faster interface. This allows the computer to communicate with very high speed.

So big that with a 695 MB / s transfer rate, the drive lags behind typical SSDs, as it bypasses the limited SATA 2 bus capable of transferring data at a maximum speed of 550 MB / s. The drive is of course a hybrid and consists of a 4TB HDD disc with a 128GB SSD installed on which the most used data is stored.

Bioactive glass will provide more durable seals?

Present composite dental fillings used by dentists are not eternal, and as Professor Jamie Kruzic of the University of Oregon says, some of them may stop fulfilling their task after six years. That is why, with his team, he is working on a completely new material that is called bioactive glass.

Currently, composites used by dentists as fillings fill holes in our teeth are made of a mixture of polymers and inert glass fillers. They are composed of compounds such as phosphorus oxide, silicon oxide and calcium oxide, which repel bacteria that cause tooth decay. Specifically speaking, calcium and phosphate released ions are toxic to them.

The problem is that bacteria can put the colon in the gaps between the filling and the tooth, causing the tooth to break from the inside. That is why researchers have developed special, bioactive glass that, as demonstrated by laboratory tests, is much more resistant to such action.

The New Horizons mission may fail

In 2006, New Horizons shipped into space to investigate celestial bodies in the Kuiper Belt near Pluto. Unfortunately, now it turns out that this mission of several years can end in total failure because there are problems with choosing the right object.

Astronomers have the biggest problem with the choice of the KBO (Kuiper Belt Object), or, in short, the proper object to investigate for the instruments of the New Horizons unit. Once the ship has reached Pluto, it must know the trajectory of the object that it should investigate in order to approach it safely. Unfortunately, finding a good KBO is not easy because terrestrial telescopes are too weak to accurately view an object and calculate its trajectory, so the chance of choosing the right celestial body is at most 40 percent.

However, the astronomers do not intend to give up so easily, so they hope to be able to use the Hubble Space Telescope for this purpose, which should increase the chances of successful missions by as much as 90 percent.

It would seem that setting up a KBO for New Horizons should be a priority, so you can ask why the issue was left at the last moment. This is not easy, as it has to wait until it can be determined exactly which ships the ship will be able to reach. This wait can be revenged, because until the last phase of the mission was only a few months before the ship will have to fire their engines and eventually pick up some trajectory.

In the Canadian library you rent the internet

By speaking to a library we mean a place where you can search for information in books or old magazines, use your computer with access to the network, or rent a book. The Canadian Kitchener Public Library has expanded this offer in addition to the possibility of renting Wi-Fi hotspots.

The Kitchener Public Library is the first library in Canada to rent Internet, specifically Wi-Fi hotspots, to access the global network. These devices function as typical hotspots, making them ideal for people who do not have internet access in their home because they do not need it or want to pay for it. That is why the library offers the possibility to rent such a device for a period of time and it is completely free.

There are altogether 19 devices available to users over 18 who have their own library card. Hotspot can be rented in the same way as a book for up to three weeks with no restrictions on the amount of data downloaded.

OnePlus One in a new color version

OnePlus One, one of the most popular smartphones currently available, is currently available in two color variants, namely Silk White and Sandstone Black. However, the manufacturer plans to expand the range of colors, or at least from a photo on one of the Chinese portals featuring a variant of the yellow panel.

OnePlus One is one of the most interesting smartphone models currently available on the market. Mainly because of the strange pre-sale system requiring consumers to have invitations. Although the rules were changed on October 27 and the calls are no longer needed, the product is still difficult to obtain, as it is currently available in one-day pre-sales, another one scheduled for November 17.

So far OnePlus One has been available in two color variants, namely black and white, but apparently the manufacturer is preparing another version. One of the Chinese portals appeared as a picture of the yellow variant. It is not known if it will be such a housing in such a color, or whether OnePlus plans to sell interchangeable panels. As you can see in the picture, the material is textured and looks really good, and its color contrasts nicely with the manufacturer's red logo. We do not know yet when the equipment will go on sale.

OnePlus One is a device with a 5.5-inch touch screen LTPS displaying images at 1920 x 1080 pixels and a quad-core 2.5GHz Snapdragon 801 processor supporting the Adreno 330 graphics. The manufacturer also installed 3 GB of RAM and 16 to 64 GB of usable memory, which can not be expanded. The smartphone also features a 13-megapixel camera with dual flash and a 5-megapixel front camera.

It is powered by a 3100 mAh battery but can not be replaced by the user, but the functionality is provided by Android 4.4.2 KitKat with a Cyanogenmod ROM overlay, with the manufacturer already announcing an update to Android 4.4.4.

Cleansing the oceans in a modern way

Earth's water reservoirs are slowly becoming a landfill of rubbish, full of heavy metals and waste floating on its surface. There is a project called Ocean Cleanup, which, thanks to the recently acquired funds, is beginning to enter the testing phase.

The purpose of Ocean Cleanup is to clean the surface of the oceans from plastic waste floating on their surface. The project was launched in 2013 by Boyana Slat, a Dutch aeronautical engineer whose vision is based on the use of tidal waves and floating arms that would naturally collect garbage from the surface of water and then bring them to a central tank from where they would be removed. . If the project proves successful, it could significantly reduce the process of purifying oceans from rubbish.

Last December announced the first phase of testing to take place in the North Sea, specifically the 23 km long coast of the Netherlands. A special, 100 meter long installation would allow you to assess the strength of the tidal waves and monitor the load on the garbage barriers as well as their movement. Such a test in real conditions will be very useful, since the barrier was checked only by means of computer models.

We have just managed to raise $ 1.5 million in funding, shared by Royal Boskalis Westminster NV, the Dutch government, and an anonymous philanthropist to carry out the planned quiz. The test installation has just been completed and will be validated for the next year in real conditions.

The new drive will reduce the cost of launching satellites

Researchers at the University of Michigan are working on a new drive that will allow us, in a fraction of the current cost, to be orbited to Earth or small satellites.

Engineers are working on a project called CAT (CubeSat Ambipolar Thruster), which aims to construct small, solar-powered CubeSat propulsion blocks that can move objects into orbit.

The new technology would significantly reduce the cost of launching satellites compared to the current heavy and heavy rocket method. Scientists expect their invention, in the future, will significantly speed up the space exploration process, enabling satellites to be sent to Saturn and Jupiter.

However, to complete their project, they need at least $ 200,000, so they decided to raise funds through Kickstarter. If they manage to gather needed resources, they may be able to send a new prototype into the space next year, and one year later they want to use it to launch space vehicles into space.

NASA needs new batteries for space missions

The US space agency needs new types of batteries that will provide astronauts with energy during multi-month space missions. It therefore offers $ 250,000 to any company that is able to offer a sensible alternative.

NASA wants to send missions much more than just the Moon in a few years, so it needs a new type of battery that will provide energy for much longer missions.

Current lithium batteries and hydrogen cells are not able to store enough current to use them for several months, so you need to develop a completely new type of battery that is much more efficient than the current one.

The space agency is primarily aiming to reduce the number of liquid fuel-based batteries that are costly to put in space. Some vehicles already use solar energy to produce the current needed to power the instruments, but the current solutions are not effective enough for major applications yet.

Apple is working on its own GPU

The Californian company starts work on its own graphics unit, which it intends to install on its smartphones. The company wants to make itself independent of its biggest rival, Samsung, delivering its GPU over five years, and by the way, to increase its revenue.

Apple makes a lot of money selling iPhones, but the company's profits would have been even greater if it had not been necessary to buy components from external vendors. Contenders have long recognized this principle, so Samsung uses Exynos processors, and Huawei is increasingly installing Kirin chips in its smartphones.

Apple has once surprised everyone by designing their own CPUs on ARM cores, and is now following the blow, and as the media reports, it starts working on its own GPU. For now, the information on this topic is very scant, so it is not known whether the US corporate engineers will achieve the performance of the graphics unit or when the system will be ready.
