For the first time ever, blood-producing stem cells have been generated in a lab. Two separate teams of researchers have come up with differing ground-breaking methods to generate these important blood-forming cells, paving the way for the development of treatments for a variety of blood diseases and also offering a clear path towards an unlimited supply of lab-made blood for transfusions.
According to the Center for Disease Control, 1.25 million people suffer from type 1 diabetes in the US alone. So far, it can only be managed with diet and regular doses of insulin, but scientists at UT Health San Antonio have invented a way of curing the disease in mice that may one day do the same for humans even with type 2 diabetes.
Sperm that’s been loaded with chemotherapy drugs could be used to fight cancer in women.
The guided missile technique involves using drug-treated sperm to deliver the medicines to tumors deep inside the body.
The revolutionary treatment could help thousands of women affected by cancers of the reproductive system, which can be reached by the drug- carrying sperm. Cancer of the womb kills more than 2,000 women a year in the UK and cervical cancer claims the lives of around 900.
Treatment includes chemotherapy to try to poison the cancer cells before they spread.
But this also damages healthy cells. For years, scientists have been exploring ways to deliver toxic anti-cancer medicines directly to tumor sites, leaving healthy tissues unscathed.
One method used bacteria as a form of transport, as they can penetrate the body easily.
The Australian funnel-web spider is generally something you’d want to steer well clear of, but the creepy crawly could soon be helping out stroke victims. A peptide found in the spider’s venom has been shown to reduce the brain damage that occurs in the hours following a stroke, with early preclinical studies involving rats having delivered extremely promising results.
Tiny magnetic beads coated in sugar could help doctors to check if a cancer has spread. Once injected into the patient, the beads can be detected using a handheld magnetic wand — similar to a metal detector — and are used to identify the lymph nodes nearest to the cancer.
The lymph nodes form part of the lymphatic system, which drains fluid from tissues all over the body back into the bloodstream. If cancerous cells get into this system, the disease can then spread to other parts of the body.
The key to determining if cancer has spread is identifying the sentinel node — the lymph node that is nearest the tumour.
There has been plenty of recent research focusing on how your gut bacteria can send messages to your brain controlling appetite and feelings of satiation, but a recent discovery by researchers from the Columbia University Medical Centre has revealed a previously unknown appetite-regulating mechanism that is secreted by bone cells.

What is the number one complaint amongst conservatives regarding healthcare? That it is completely void of the free market. Whether it is ObamaCare, or what we currently know of RyanCare, for all intents and purposes, the free market simply doesn’t exist.
We on the right understand that free market forces like competition and innovation are the keystones to any successful industry – any mutually beneficial transaction. Insurance is no different.
Health Insurance, which, to reiterate for the thousandth time, is not healthcare, anymore than auto insurance equals car repair, etc. We would never think of attempting to use our auto insurance for a tire change or a new muffler. Yet we don’t think twice about using our health insurance when we see a doctor for the common cold.
And why? Simple, as we know. It’s called third party payer, or worse, single payer. As long as we perceive that someone, the insurance company, will pay for the visit, we don’t ask what the charges are before service is rendered. We don’t ask after the services are rendered, nor do most even care. It’s the antithesis of the free market.
According to the World Health Organization, snakes bite an estimated 5 million people each year, killing more than 100,000 of those victims and permanently injuring hundreds of thousands more. Current antivenoms might not be saving lives as efficiently as they could be, given that they’re difficult and expensive to produce, distribute and administer. Now, researchers at the University of California, Irvine (UCI) have developed a synthetic alternative with a long shelf-life that can neutralize the venom from several species of snakes.
Using stem cells to create insulin-producing beta cells that could be transplanted into diabetics is being investigated as a possible cure for type 1 diabetes and treatment for type 2, but new research suggests that a special diet could reprogram cells in the pancreas to do the same thing.
We’re all familiar with the inescapable effects that the march of time has on our bodies, but the processes that drive aging are still offering up surprises. Scientists have long known that DNA segments called telomeres play a crucial part in our aging process, but new research has discovered a protein that acts as a kind of cellular timekeeper, regulating the length of telomeres to maintain healthy cell division and prevent the development of cancer.
