Have Scientists Found a Cure for BLINDNESS?

Some 285 million people are thought to be visually impaired across the world.

But now scientists have discovered a method for generating several key types of eye tissue from human stem cells.

They have used the finding to restore vision in rabbits and the findings offer hope that in years to come, blind people could be treated in a similar way to help them see again.

Scientists have discovered a method for generating several key types of eye tissue from human stem cells. This image shows how human stem cells grow over several weeks to spontaneously form four zones each of which has a characteristic of a different part of the eye, therefore mimicking whole eye development

The eye is composed of highly specialised tissues that are derived from a variety of cell lineages during development.

Previous studies have shown that particular cell types, such as those that make up the retina or cornea, can be created in the laboratory from so-called pluripotent stem cells.

Could This Be the End To All Cancer?

These are exiting times in the world of cancer research. I recently reported on a childhood leukemia cure – and now we see the possible end to all cancers within 2-5 years!!

Cancer’s Achilles’ heel has been pinpointed by British scientists, raising hopes of a revolution in treatment – and even a cure.

In future, patients could be given bespoke therapies that hunt out and destroy every single cancer cell, wherever it is in their body.

The first people could be treated in as little as two years and, eventually, everyone from those in the early stages of cancer, to those who are riddled with the disease could benefit. read more

3D-Printed Ear, Bone and Muscle

A baby-sized ear structure was bioprinted and implanted in a mouse and went on to show signs of vascularization one and two months later.

3D printed tissues and organs have shown real potential in addressing shortages of available donor tissue for people in need of transplants, but having them take root and survive after implantation has proven difficult to achieve. read more

GMO IS A LIFESAVER

by: the Common Constitutionalist

Practically everyone has heard the term GMO and thanks to whacky leftist publications and advocacy groups, people believe GMO to be synonymous with evil of some sort.

Chances are that unless you’ve been conned into believing the anti-GMO propaganda and eaten only unprocessed or organic foods for the past 22 years, you’ve been consuming Genetically Modified Organism foods. They have been approved and sold since 1994.

GMO crops have saved millions of lives throughout the world by modifying plant DNA to cause them to be more resistant to drought, disease and insects. GMO crops are able to be modified to grow faster, larger and cheaper thus enabling many more people to be fed than would otherwise.

But leftist advocates insist that the mad scientists who create the Franken-plants are bought and paid for with dirty agro-corporate money, are only interested in profits and are messy about with Mother Nature. These are the same whack-jobs who would prefer people in Third World nations starve to death rather than have the ability to grow or consume GMO crops. read more

Worm Inspires Wet Adhesive

Science has turned its torch to many corners of the animal kingdom in the pursuit of advanced adhesives. Immoveable mussels, grippy geckos and stubborn shellfish have helped nudge these efforts along in the past, and now another critter has emerged with a few sticky secrets of its own. read more

Javey and his team set out to develop a device that tracks key chemicals in real-time and can be worn comfortably while the subject moves around during exercise

Our sweat contains a bunch of useful information about our bodies, but diving in to retrieve it hasn’t always been so straightforward. Eyeing a future where wearables not only track our heart rate and activity, but things like hydration and muscle fatigue as well, Berkeley engineers have developed a flexible sensor that can measure biochemicals in perspiration in real-time to build a more complete picture of our well-being.

A team of researchers from the University of Michigan has developed a new technique to aid bone repair, using polymer nano-shells to deliver microRNA molecules. The method could one day have a big impact on regenerative medicine, directing cells already present at injury sites to aid healing. read more

Kill Cancer With One Fifth the Dose

The new technique has also shown promise as a diagnostics tool (Credit: Shutterstock)

The chemotherapy drug paclitaxel is commonly used to treat breast, lung and pancreatic cancers, slowing their growth by preventing cancerous cells from replicating. But once administered the drug is attacked by the body’s defenses, necessitating larger doses that result in complications such as joint pain, diarrhea and an impaired ability to fend off other infections. Researchers have now discovered a way to sneak the drug through to the tumor with its entire payload intact, a technique that could make for more effective cancer treatments with fewer side effects. read more

Vision Correcting Contact Lense

The latest trial results showed that special contact lenses designed to reshape the eye’s curvature could be used like ‘braces’ to slow the development of short sightedness in children.

Findings published in published in the Advances in Ophthalmology And Visual Systems journal show that the lenses, which should be worn overnight, reshape the curve in the eye while the wearer sleeps.  read more

As the liquid metal dissolves it releases gallium ions, which the researchers say further boosts the effectiveness of anticancer drugs

Scientists are increasingly turning to nanoparticles in search of new ways to treat cancer. Tiny nanorobots that way through the bloodstream and microscopic particles that blow up diseased cells are a couple of menacing examples. But none sound quite so ominous as a new technique under development at North Carolina State University (NCSU). Its researchers have designed liquid metal particles they describe as “Nano-Terminators” that latch onto cancer cells to more effectively deliver drugs that kill them off. read more
