Scientists have been able to restore vision in blind rabbits by creating eye tissue from human stem cells, Stem cells are a class of undifferentiated cells that are able to differentiate into specialized cell types.

Commonly, stem cells come from two main sources:
Embryos formed during the blastocyst phase of embryological development (embryonic stem cells) and Adult tissue (adult stem cells) development that could lead to human trials to help restore vision
within the next two years.

Researchers from the Cardiff University and Osaka University in Japan concur to grow multiple different cells similar to those found in the eye. They created the cells to be similar to cells in the cornea, and were able to surgically repair the front of the eye in a blind rabbits.
The scientists behind the work say the sucess could lead to clinical human trials of anterior eye transplantation to restore loss of damaged vision.

Andrew Quantock from Cardiff University, who coauthored the work, explained that the research -- published in the journal Nature -- shows that human stem cells are able to take on the characteristics
of the cornea, lens and retina.

We've been using human iPS cells-which are induced pluripotent stem cells --growing them in a 2D culture dish.

Spontaneously after several weeks, the cells create four zones on their own, Quantock told WIRED. Each zone has the molecular characteristics of a different part of the eye.
We took cells from the third zone, which most looks like the corneal epithelium, and grew them further out before transferring them onto the animal model, which was functional and worked."
The scientists were able to show that the corneal cells could be cultivated and transplanted onto the eyes of "rabbits with experimentally induced blindness" to repair the front of the eye.

Dell took the wraps off its new set of Windows 10 Pro-running Latitude system and 2-in-1 devices in India starting from Rs. 44,999.


The highlight of the launch event were the Dell Latitude 13 (7370) Ultrabook and the Latitude 12 (7270) detachable notebook, the company also advertise its revamped Latitude 3000 and Latitude 5000 series.

The Dell Latitude 13 (7370) 7000 Series Ultrabook, the company claims, It's  the world's
smallest 13-inch business class Ultrabook and is mainly for on-the-go users.The USP of the
laptop is its 13.3-inch Infinity Edge display, It will be available in full-HD resolution non-touch and
QHD+ resolution Touch display variants.

The outer view of the laptops are built using 40ton carbon fiber making it durable. Some of the connectivity features carried by the Latitude 13 7370 include USB Type-C ports, Wi-Fi, Bluetooth v4.1, Micro-USB 3.0 with support for Thunderbolt 3, 4G LTE support, microSD card reader, and Micr-SIM card slot. As for the security, users get a smartcard reader, fingerprint reader, and RFID reader, apart from security and encryption software.

(AMD)— It's the most common cause of blindness in the Western world and there is no cure.
Age-related Macular Degeneration (AMD) affects around 15 million people in the U.S. alone, and globally up to 30 million.

For most victims, vitamins and pain relief are the best treatment initially available.
But Professor Pete Coffey of University College London is pioneering a new therapy that could stop the disease in its tracks, and restore vision to the blind, through the:
London Project to Cure Blindness .

Researchers in the U.K. have developed a way of storing digital data inside tiny structures contained in glass.

The storage technology is so stable and safe that it can survive for billions of years, scientists at the University of Southampton: said this week .

That's a lot longer than your average computer hard drive.

This technology can secure the last evidence of our
civilization: all we've learned will not be forgotten," said
Peter Kazansky, a professor at the university.

Wow "check-out this technology:
It can secure and save data for the next 20th generation.

The latest version of Google's Android operating system Marshmallow is now work on 2.3% of all Android devices.



Android Lollipop is the most popular version of Android, with the OS running on 36.1% devices.

Marshmallow adoption may look poor, however, it still appears to have accepted pace in the last month with several OEMs, like
Samsung and LG rolling out
Android, Marshmallow update to their devices.

Obesity and associated lifestyle diseases are not restricted to the developed world. In fact, a growing number of emerging economies are finding that as obesity rises, so too do preventable conditions such as diabetes, hypertension, coronary heart disease  and  stroke.               

 In South Africa, around one in four adults are obese, according to media fact-checking organisation Africa Check and the World Health Organisation. According to the WHO, 13% of adults globally were classified as obese in 2014.

Measuring body-fat percentage is an important way to monitor and  manage obesity and related illness, but accurately calculating body fat  percentages is surprisingly difficult. With the recent installation of its bone densitometry system in South Africa, GE Healthcare is making muscle and fat measurement a lot easier.

The technology identifies exactly how much muscle and fat is in the body and where it is located, helping doctors and their  patients easily target zones for weight loss, advise on lifestyle changes and plan customised exercise routines, explains Tessica Chetty, an advanced applications specialist for GE Healthcare.
The same technology can also be used in osteoporosis management, as it assesses bone strength and can predict the likelihood of bone fractures.

In body-building competitions, the fat-to-muscle ratio is of utmost importance. Recently, the Worcestor Mediclinic, in South Africa’s Western Cape province, worked with a body builder to calculate her body-fat percentage using the bone densitometry system, providing valuable data to prepare her  for competitions. Even her left and right arms were compared to determine  minute differences in muscle and fat, with the results determining final preparations for competition.
Deidre Laing, a radiographer at Worcester Radiology, says she decided  to work with the body builder in order to get a better understanding of the machine’s capabilities.

The bone densitometry system is also useful for non-bodybuilders. Laing has used the same technology to track changes in body fat percentages over time in a single patient. During the study, an initial scan was taken prior to any diet or exercise interventions.
Following this, the patient went on a diet, after which the scan was repeated. She continued with the diet and added an exercise plan drawn up by a biokineticist based on problem areas highlighted on the scan. A third scan was able to show marked improvement after these interventions.

“You can actually see how you’re losing weight,” she says. As a result, patients are far more motivated to make healthier lifestyle decision.

Bone densitometry, like other medical scanning technology, empowers both patients and doctors with information they need to make informed decisions on treatment and diagnosis based on facts rather than guesswork. Now that we increasingly recognise the role of lifestyle decisions in maintaining good health, personalised healthcare information is set to become even more necessary.
