Dr. Greengard’s research described how cells react to dopamine, an important chemical messenger in the brain. His work provided the underlying science for many antipsychotic drugs, which modulate the strength of chemical signals in the brain.
“Our work shows the details of how dopamine produces these effects — in other words, what’s wrong in these diseases and what can be done to correct them,” Dr. Greengard said.
A team has proposed using nanobots to create the ‘internet of thoughts’, where instant knowledge could be downloaded just by thinking it.
An international team of scientists led by members of UC Berkeley and the US Institute for Molecular Manufacturing predicts that exponential progress in nanotechnology, nanomedicine, artificial intelligence (AI) and computation will lead this century to the development of a human ‘brain-cloud interface’ (B-CI).
Writing in Frontiers in Neuroscience, the team said that a B-CI would connect neurons and synapses in the brain to vast cloud computing networks in real time.
We have known since the 19th century that young blood has surprising curative and rejuvenation abilities. It’s quite strange, but it happens to be true. In recent years, scientific efforts to understand what it is about young blood that causes rejuvenation have ramped up.
We now know that young and old mice with surgically connected circulatory systems will experience altered aging: the young mouse will prematurely grow old, and the old mouse will, in many cases, miraculously grow young. This is known as heterochronic parabiosis, and it is a large source of the legitimate excitement about the potential of young plasma to lead to human rejuvenation [1].
The challenge, of course, is how to achieve these benefits in more acceptable and less disturbing ways.
The cause of cancer is written into the DNA of tumours, scientists have discovered, in a breakthrough which could finally show how much disease is attributable to factors like air pollution or pesticides.
Until now the roots of many cancers have proved elusive, with doctors unable to tease out the impact of a myriad of carcinogenic causes which people encounter everyday.
Even with lung cancer, it is not known just how much can be attributed to smoking and how much could be linked to other factors, such as living by a busy road, or inhaling pollutants at work.
Israeli researchers have printed a 3D heart using a patient’s own cells, something they say could be used to patch diseased hearts — and possibly, full transplants.
The heart the Tel Aviv University team printed in about three hours is too small for humans — about 2.5 centimeters, or the size of a rabbit’s heart. But it’s the first to be printed with all blood vessels, ventricles and chambers, using an ink made from the patient’s own biological materials.
Researchers have invented a new type of cancer immunotherapy by injecting tumours with a series of stimulants. The experimental therapy attracts the body’s own immune system’s attention, so it can come and destroy the cancerous masses.
The radical new approach has already shown promise in patients with an advanced form of non-Hodgkin’s lymphoma that resists conventional treatments, and is currently being tested on a variety of stubborn cancers.
The result can be described as turning the tumours into “cancer vaccine factories”, because attracting the body’s immune cells to the cancer site is a method known as in situ vaccination.
