Un paciente que tenía beta-talasemia (una enfermedad hereditaria de la sangre) ya no necesitaba transfusiones continuas, y otro, con anemia falciforme, dejó de sufrir vasos obstruidos. Así lo anunció la empresa Crispr Therpautics.
Toshiba has invented a machine that can detect 13 types of cancer using just a single drop of blood in record time: in just two hours, people will have a full diagnosis for the ridiculous price of $180 or under with more than 99% accuracy.
This is Star Trek-level stuff.
LONDON (AP) — Four African countries have reported new cases of polio linked to the oral vaccine, as global health numbers show there are now more children being paralyzed by viruses originating in vaccines than in the wild.
In a report late last week, the World Health Organization and partners noted nine new polio cases caused by the vaccine in Nigeria, Congo, Central African Republic and Angola. Seven countries elsewhere in Africa have similar outbreaks and cases have been reported in Asia, including the two countries where polio remains endemic, Afghanistan and Pakistan.
In rare cases, the live virus in oral polio vaccine can mutate into a form capable of sparking new outbreaks. All the current vaccine-derived polio cases have been sparked by a Type 2 virus contained in the vaccine. Type 2 wild virus was eliminated years ago.
New research in mice finds that blocking a key molecule can slow the progression of multiple sclerosis. The findings pave the way for new treatments.
As genetic sequencing becomes more widespread, a disconnect is emerging between what individual patients expect to get back and what scientists are willing and able to tell them. WSJ visited MIT’s Broad Institute to learn about the murky world of genomic research data.

Sugar poses one of the most pressing health problems in the modern world – not least because it’s just so delicious. Rather than quitting sweets cold turkey, low-calorie alternatives to sucrose could make tasty treats that are at least less bad for us. And now, researchers from Tufts University have developed a more efficient method for producing one such sweetener, using farms of bacteria.
The sugar in question is called tagatose, which the FDA says is “generally regarded as safe.” It’s 92 percent as sweet as sucrose – regular old table sugar – but because the human digestive system doesn’t metabolize as much of it, it only has 38 percent of the calories. That, in turn, means tagatose has a much smaller effect on blood glucose and insulin, making it safe for diabetics. And to cap it off, tests show that it doesn’t contribute to cavities or tooth decay.
But, of course, there’s a catch – tagatose is a little complicated to produce. Normally, it’s done by hydrolyzing lactose to make galactose, which is then isomerized into tagatose, which then needs to be purified and crystallized into a solid, usable form. Yields from this process are low, at less than 30 percent.
When you hear the word “cyborg,” scenes from the 1980s films RoboCop or The Terminator might spring to mind. But the futuristic characters made famous in those films may no longer be mere science fiction. We are at the advent of an era where digital technology and artificial intelligence are moving more deeply into our human biological sphere. Humans are already able to control a robotic arm with their minds. Cyborgs —humans whose skills and abilities exceed those of others because of electrical or mechanical elements built into the body —are already among us.
But innovators are pushing the human-machine boundary even further. While prosthetic limbs are tied in with a person’s nervous system, future blends of biology and technology may be seen in computers that are wired into our brains.
Our ability to technologically enhance our physical capabilities—the “hardware” of our human systems, you could say—will likely reshape our social world. Will these changes bring new forms of dominance and exploitation? Will unaltered humans be subjected to a permanent underclass or left behind altogether? And what will it mean to be human—or will some of us be more than human?
Can you actually make a disease disappear? Dr Rangan Chatterjee thinks you can. Often referred to as the doctor of the future, Rangan is changing the way that we look at illness and how medicine will be practised in years to come. He highlighted his methods in the groundbreaking BBC TV show, Doctor In The House, gaining him much acclaim from patients, his contemporaries and the media.
He is the author of the international bestseller, The 4 Pillar Plan — http://amzn.to/2yGfpuB which has been released in the USA and Canada under the title, How to Make Disease Disappear — https://amzn.to/2GstJf6 Rangan’s 15 years of clinical experience in the NHS includes internal medicine, immunology and general practice. A pioneer in the emerging field of progressive medicine, he also uses techniques from other disciplines he has studied including movement kinetics and functional medicine.

Supplements may appear harmless enough—but beware.
Chemotherapy-treated cancer cells that enter a non-dividing state called senescence can nevertheless boost cancer growth. The finding that these cells eat neighbouring cells reveals a mechanism that enables senescent cells to persist. Chemotherapy-treated tumours boost their survival by ingesting cells.
