DNA reveals origin of Stonehenge builders
Posted by Genevieve Klien in category: biotech/medical
The ancestors of the people who built Stonehenge travelled west across the Mediterranean before reaching Britain, a study has shown.
Researchers in London compared DNA extracted from Neolithic human remains found in Britain with that of people alive at the same time in Europe.
The Neolithic inhabitants appear to have travelled from Anatolia (modern Turkey) to Iberia before winding their way north.

90 New Cases of Measles Reported in U.S. as Outbreak Continues Record Pace
Posted by Genevieve Klien in categories: biotech/medical, health
The number of new measles cases in the United States rose again this month, the Centers for Disease Control and Prevention said on Monday, bringing the total number to 555 in 2019. This year’s outbreak is on course to be the worst since the country eliminated measles as an endemic disease in 2000.
Health authorities reported 90 additional cases as of April 11, with outbreaks in New York, Washington, California, New Jersey and Michigan, up from 78 the week before. Those cases were largely linked to travelers returning from countries seeing outbreaks of their own, including Israel, Ukraine and the Philippines.
The disease then spread through populations in which large numbers of people are unvaccinated, the C.D.C. said.

Paul Greengard, 93, Nobel Prize-Winning Neuroscientist, Is Dead
Posted by Genevieve Klien in categories: biotech/medical, neuroscience
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.

Scientists propose putting nanobots in our bodies to create ‘global superbrain’
Posted by Quinn Sena in categories: biotech/medical, internet, nanotechnology, robotics/AI
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.

An Interview with Dr. Steven Braithwaite of Alkahest
Posted by Steve Hill in categories: biotech/medical, life extension
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.

Cause of cancer is written into DNA of tumours, scientists find, creating a ‘black box’ for origin of disease
Posted by Genevieve Klien in categories: biotech/medical, sustainability
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.
