Size of Brain Region May Impact How Well Exposure Therapy Works for PTSD

Posted by in categories: biotech/medical, health, neuroscience

Interesting read on PTSD. Wonder how much this plays into DARPA’s own research around memory removal on PTSD patients. hmmm.

New research suggests that PTSD patients with a larger region of the brain that helps distinguish between safety and threat are more likely to respond to exposure-based therapy.

The study expands upon prior research that discovered having a smaller hippocampus is associated with increased risk of PTSD.

How nanotechnology could detect and treat cancer

Posted by in categories: biotech/medical, nanotechnology, neuroscience

The crew of the Proteus has one desperate chance to save a man’s life. Shrunk to the size of a large bacterium, the submarine contains a team of scientists and physicians racing to destroy a blood clot in the brain of a Soviet defector. The group journeys through the body, evading giant white blood cells and tiny antibodies while traveling through the heart, the inner ear and the brain to reach and destroy the blockage.

Although events in the film Fantastic Voyage were far-fetched when it was released in 1966, they’re now being realized every day in labs around the world, particularly in cancer treatment. A growing field called nanotechnology is allowing researchers to manipulate molecules and structures much smaller than a single cell to enhance our ability to see, monitor and destroy cancer cells in the body.

Tens of thousands of patients have already received chemotherapy drugs delivered by nanoparticles called liposomes, and dozens of other approaches are currently in clinical trials. Within the next five to 10 years, our bodies’ biggest defenders may be tinier than we could have ever imagined.

The bionic skin that can feel a tumor

Posted by in categories: biotech/medical, cyborgs, neuroscience, transhumanism


Our skin is our largest organ. A gateway between our brain and the rest of the world.

Imagine then a scene where skin could communicate what’s going on inside a human body. It could inform surgeons, provide alerts when our body is about to fall ill, or even diagnose diseases inside another human being, simply through the sense of touch.

An Interview with the Advocates of the Major Mouse Testing Program Team

Posted by in categories: biotech/medical, health, life extension

New MMTP Interview on Fightaging! discussing longevity, advocacy and the urgent need to support research!

By way of following on from today’s AMA over at /r/futurology, I recently had the chance to ask a few questions of the Major Mouse Testing Program (MMTP) volunteers, a mix of scientists and advocates who aim to do their part to speed up progress towards effective treatments for the causes of aging. The group formed six months ago or so, and are presently seeking funds for their first mouse studies through crowdfunding with the organization. The initial focus is on senolytic treatments capable of removing senescent cells from old tissues. I encourage you all to take a look at the details of their research proposal.

Growth in the number of dysfunctional, senescent cells is a contributing cause of degenerative aging, involved in the progression and pathology of all of the common age-related diseases. A growing body of evidence supports the outright removal approach as a way to minimize or eliminate this portion of the aging process. Unfortunately there is — as ever in the aging research field — a paucity of funding and always the need for more and better animal data in order to pull in other players with deep pockets. At this stage in the progression from laboratory to clinic, prior to the involvement of any large institutions or companies, all such efforts are important work. I’m pleased to have been able to contribute to this Major Mouse Testing Program fundraiser, and hope to see great things from this group in the future.

Should we synthesise a human genome?

Posted by in categories: biotech/medical, ethics, genetics, law

As specialists gather in private to discuss a grand plan for constructing a human genome, Drew Endy and Laurie Zoloth argue that such an enormous moral gesture should not be discussed behind closed doors.

At Harvard today, an invitation-only group of about 150 scientists, lawyers, and entrepreneurs, met to discuss if and how to construct from scratch an entire human genome – the heritable genetic material that in nature is transferred from parents to children.

MMTP AMA Senolytics: Seek and Destroy! • /r/Futurology

Posted by in categories: biotech/medical, health, life extension

On Reddit Futurology today!

The Major Mouse Testing Program is an ambitious project of the International Longevity Alliance, featuring an international team of scientists and advocates testing therapies against aging decline. This experiment is is lead by world class stem cell researcher Dr Alexandra Stolzing and was inspired by our scientific advisor and colleague Dr Aubrey De Grey.

The Major Mouse Testing Program is seeking to speed up scientific progress in the field of regenerative medicine and bio-gerontology. After ILA experts conducted an analysis of delays preventing the development of life extension technologies, it was shown that a serious problem was the lack of robust animal data for the potential of different compounds to promote health and extend maximum lifespan. Without this data promising interventions cannot enter clinical trials and become available to the general public.

Scientists Hold Secret Meeting to Consider Creating a Synthetic Human Genome

Posted by in categories: biotech/medical, genetics

George Church, a professor of genetics at Harvard Medical School and an organizer of the proposed project, said there had been a misunderstanding. The project was not aimed at creating people, just cells, and would not be restricted to human genomes, he said. Rather it would aim to improve the ability to synthesize DNA in general, which could be applied to various animals, plants and microbes.

The project poses ethical issues about whether humans could be created without parents.
