Nokia confirms it will release a smartphone next year

  Nokia confirms it will release a smartphone next year Nokia has confirmed that its upcoming smartphone will be released next year, making good on its promise to re-enter the mobile phone market.The once-mighty Finnish company sold its device business to Microsoft in 2014, where phones were sold under the Lumia brand. But as Microsoft effectively exits the smartphone business, Nokia is set to return.The new generation of devices are expected to be released in the second quarter of 2017, with rumours suggesting that they will be unveiled at Mobile World Congress in February.

It can image and analyze DNA sequencing reactions, and detect point mutations in preserved tumor samples.

The microscope was created as a low-cost means for targeted DNA sequencing and tumor analysis to be conducted at the point-of-care (POC) in resource-limited areas. Those locations, which sit far away from any labs or hospitals, do not receive the required POC needed to sufficiently manage a wide range of disease, according to the report published in Nature Communications.

Say hello to the new Nokia, coming in 2017

  Say hello to the new Nokia, coming in 2017 Effort promises more than your typical "zombie brand" resurrection.The new Nokia seems to have more potential than your usual licensed "zombie brand" setup. Typically, when a brand dies (in Noka's case, just the phone division died), it gets snapped up by some no-name company, which proceeds to slap the brand name on everything under the sun. This lovely line of Polaroid Android tablets from brand buyer "PLR IP Holdings, LLC." is a great example.

Scientists for the first time have successfully edited genes in human embryos to repair a common and serious disease-causing mutation , producing apparently Scientists have long feared the unforeseen medical consequences of making inherited changes to human DNA. The cultural implications may be

The hope is that smartphones, with their CMOS imaging sensors and powerful computing capabilities, can supply a cost-effective alternative to current imaging, and enable low-cost diagnostic analysis from anywhere in the world.

The scientists set out to test the idea that current mobile phones provide sufficient imaging to help remotely diagnose diseases like cancer, "with spatial resolution and image quality matching high-end pathology microscopes."

They smartly chose the lens unit from a Nokia Lumia 1020, a Windows Phone released in 2013. That device packs a now-legendary 41-megapixel Carl Zeiss-branded rear-facing camera (it deserves every hyphen), which researchers say offers a magnification factor of 2.6x. A used 1020 can be purchased on Ebay for a measly $100, offering an appealing megapixel-per-dollar ratio.

Budget Smartphones To Look Out For In 2017

  Budget Smartphones To Look Out For In 2017 The year 2017 is expected to be the year when budget smartphones are endowed with improved technology at reduced prices.Here are five budget phones expected to release in 2017:

Scientists have discovered that between one and 10 mutations are needed for cancer to emerge. This approach could be used in the future to help clinics identify the few mutations , among " We now know of hundreds of genes , that when mutated , drive cancer . This research shows that across

Sequence - and structure-based analyses identified >3,400 putative missense driver mutations supported by multiple lines of evidence. Our study represents the most comprehensive discovery of cancer genes and mutations to date and will serve as a blueprint for future biological and clinical

The Nokia lens was coupled with laser diodes and 3D-printed pieces before going through a series of rigorous tests, including sequencing of the KRAS gene, which can cause normal cells to become cancerous when mutated. It was also used to look at preserved tumors for point mutation analysis.

The research team came away with some positive results.

“In conclusion, mobile-phone-enabled molecular diagnostic analysis may provide a simple, cost-effective, and yet powerful means to integrate molecular marker information with traditional morphology analysis and might further help digital molecular pathology become widely accessible at POC offices and even in resource-limited settings."

The document went on to list additional benefits from the makeshift microscope, including diagnosing infectious diseases by measuring antibiotic resistance markers.

It is refreshing to see a potentially life-saving experiment fueled by aging devices that we so easily discard. Who knows, in a few years, we may be able to map genes and diagnose cancer from any location thanks to a camera unit Nokia made back in 2012.
