The clear albumen surrounding an egg’s yolk was spun into a super-thin wafer used in a degradable chip known as a memristor
Durability is often touted as the hallmark of good electronics, but sometimes you want components that don’t last all that long. For example, it would be handy if microelectronic systems that delivered drugs to various parts of the body dissolved after their task was done. Or if sensors that monitor pollution simply dissolved after they were finished reporting, rather than contributing to even more environmentally-damaging material. A team of researchers from the UK and China has just figured out how to create one such chip out of eggs.
People paralysed from the neck down will soon be able to move robotic arms by thought alone thanks to wi-fi, according to a world-leading expert.
The first patients will be implanted with the devices by 2018, Professor John Donoghue told The Mail on Sunday.
Animals that regrow body parts like zebrafish and newts certainly function very differently to the way humans do, but we might one day be able to borrow some of these traits. A closer look at the mechanism driving these remarkable regenerative abilities has suggested that they could be recreated in mice, with the scientists involved hopeful it could ultimately improve our capacity to regrow damaged body parts.
Diabetes is a widespread health problem, affecting some 400 million people across the planet. With that number only set to rise, it’s important that we find new treatments as quickly as possible. Researchers at the University of Montreal are making significant progress in that regard, discovering a common genetic defect in beta cells that may be a big factor in both Type 1 and Type 2 diabetes.
Modern medicine may be upgrading centuries-old techniques to repair wounds that just won’t heal.
Researchers from North Carolina State University and Massey University in New Zealand have found that genetically engineered maggots can clean non-healing wounds and promote cell growth.
This is done using a human growth factor, which the maggots secrete while removing dead tissue.
Your saliva is possibly not something you have given much thought to – but it plays a vital role in maintaining good health, says Gordon Proctor, a professor in salivary biology at King’s College, London.
‘Saliva is a remarkable substance. It might be 99 per cent water, but it is far more than that,’ he says.
In fact, saliva carries the same bacteria found in your gut, as well as powerful substances that fight germs and promote wound healing – which might be why we instinctively pop our finger in our mouth if we cut or graze it.
Now, it is being used to detect serious disease. The University of California, Los Angeles recently announced that it had developed a £15 saliva test to spot early-stage lung cancer before it can be detected with a blood test.
The test looks for fragments of tumor DNA in a single drop of saliva, and can give a result in less than ten minutes.
A new procedure, which alters a person’s immune system, could offer a breakthrough in transplant surgery allowing patients to receive kidneys from incompatible donors, experts have revealed.
Patients are currently forced to wait for a kidney to become available from a deceased donor.
