NASA plans mission to Europa 

NASA is planning a mission to Europa which is known as Jupiter’s Icy Moon. The mission that will cost NASA $30 million is one of the most desired projects of the researchers and astronomers at NASA.

Europa has always interested researchers as it is said to contain large amounts of frozen water beneath its surface. Planetary scientists also speculate that there could be oceans of briny water under the shell of Europa.

Teams at NASA suggest that the mission will probably be unmanned and will involve a spacecraft that will orbit Jupiter, making regular visits to Europa. The spacecraft will not be landing or orbiting the planet’s moon itself. This is due to safety reasons as Europa is located in the region which is surrounded by harsh radiations. NASA will conduct a selection of instruments and equipment this year for the mission and is considering the launch date of the mission to be around mid-2020.

Hydrogels: the killer transporter Hydrogels are special materials that are used to absorb moisture. They are commonly used in diapers and contact lenses to control humidity. Chemical engineers have now come up with a better use of hydrogels by developing a new technology that is based on thermo-sensitive nano particles or nano hydrogels that will be used in the field of medicine. These newly developed devices will be used to deliver anti-cancer drugs.

Engineers at the University of Guadalajara have come up with this idea of using hydrogels in a way that when injected into the human body, the immune system doesn’t detect or attack them when they pass through the blood circulation system. In other words, these drug carriers are designed to be compatible with the human body. The concept behind this device is the hydrogels carry the anti-cancer drugs and deliver them straight to the infected area where they can be released without damaging other parts of the body. This is due the chemical and physical properties of hydrogels as they offer the possibility of dosing a myriad of active substances on the site desired and can be administered as dry or swollen hydrogels by different routes: oral, nasal, buccal, rectal, transdermal, vaginal, ocular and parental. Drug release may come by a volume increase, changes in pH, or temperature.

The nano-hydrogels have shown very good characteristics of biocompatibility with the human organism, due to their physical properties, which make them resemble living tissues. Their high water content, soft and elastic consistency, and low interfacial tension prevent them from absorbing proteins from body fluids. Hydrogels are being used primarily in the biomedical area as investigative and diagnostic tools in membranes, coatings, microcapsules, implants for applications and applications for drug release. Also, the nano-hydrogels are used to regenerate tissue or mend fractures, serving as substrates for cell growth. Other forms of drugs known as molecular target drugs are already used against cancer, but the advantage nano-hydrogels have is that they can attack only the cancer cells or tissues without damaging healthy body parts.

Geeky Glees:

Canon`s new 750D DSLR:
The Pixel PowerCanon recently announced its new DSLR camera calling it the 750D, a successor to the previous 700D model. Canon has bumped up its pixel sensor to 24 MP from the previous 18 MP. The new 24 megapixel sensor which is made by Canon features the new version of its Hybrid CMOS auto focus system. The new system uses phase detection, focusing pixels spread across the sensor to aid faster autofocus in live view mode and when shooting movies. The latest sensor has more focusing pixels in a regular array.

Canon states that this new system is almost two generation ahead of its previous entry level DSLRs. This new system also gives Canon an upper hand over its rival Nikon. Nikon produces D3300 and D5500 in the same DSLR range. This increase in resolution has left no impact on the ISO range which goes from 100 to 12800. The processor installed is Canon`s DIGIC 6 processor. The camera has 5fps continuous shooting and 19-point autofocus system. The previous models came with 9-point focus system and the DIGIC 5 processor. The camera also features an articulating 3-inch touch screen display. The camera is capable of shooting HD movies at 30 fps, 25fps and 24 fps. Canon has also embedded the flicker detection technology for more reliable shooting under artificial light.

Samsung Portable T1 SSD External Hard drive The new T1 SSD (Solid State Drive) external hard drive from Samsung is here to fulfil all your needs for storing. It is small, light, and amazingly fast and also comes with 256 bit encryption. It’s a USB 3.0 device which is very thin. The dimensions of the Samsung T1 hard drive are 2.8 inches (71mm) long by 2.1 inches (53mm) wide, and the T1 weighs in at about 1.06 ounces (30 grams).

Samsung incorporates its V-NAND technology into the T1 series of devices. This technology helps in dealing with memory and corruption issues. When the size and memory and size of the device get smaller, the data tends to get corrupted and eventually lost. This is because the memory cells get closer and closer and the interface between these cells increases. This technology helps in eliminating the possibilities of data corruption, using less power and also increases the operating speed of the drive. This hard drive also comes with 256 bit encryption by which you can lock the hard drive and set up a simple password for access without installing any other third party applications. This SSD External Drive is available in 250 GB, 500 GB and 1 TB with write and read speed of 450 MBps.

Geeky Alerts! The World’s first microprocessor was created in 1971, called the 4004 by Intel. It contained 2300 transistors.

The Google homepage is so simple because when it was created, neither Larry Page nor Sergey Brin knew HTML

In 2007 a researcher from IBM was able to gain complete control of an American nuclear power plant by hacking it over the internet.

SciencSational Stuff!! 

The oceans contain enough salt to cover all continents to a depth of nearly 500 feet.

Jupiter`s moon Ganymede is the largest moon in our solar system. It is larger than the planet

Mercury, and is the first moon known to have its own magnetic field.
