Young microglia restore amyloid plaque clearance of aged microglia

Posted by in categories: biotech/medical, neuroscience

Rejuvenating the immune system offers hope for Alzheimer’s patients and removal of plaques.

Alzheimer′s disease (AD) is characterized by deposition of amyloid plaques, neurofibrillary tangles, and neuroinflammation. In order to study microglial contribution to amyloid plaque phagocytosis, we developed a novel ex vivo model by co‐culturing organotypic brain slices from up to 20‐month‐old, amyloid‐bearing AD mouse model (APPPS1) and young, neonatal wild‐type (WT) mice. Surprisingly, co‐culturing resulted in proliferation, recruitment, and clustering of old microglial cells around amyloid plaques and clearance of the plaque halo. Depletion of either old or young microglial cells prevented amyloid plaque clearance, indicating a synergistic effect of both populations. Exposing old microglial cells to conditioned media of young microglia or addition of granulocyte‐macrophage colony‐stimulating factor (GM‐CSF) was sufficient to induce microglial proliferation and reduce amyloid plaque size. Our data suggest that microglial dysfunction in AD may be reversible and their phagocytic ability can be modulated to limit amyloid accumulation. This novel ex vivo model provides a valuable system for identification, screening, and testing of compounds aimed to therapeutically reinforce microglial phagocytosis.

Incoming Star Could Spawn Swarms of Comets When It Passes Our Sun

Posted by in categories: existential risks, space

For years, scientists have known that Gliese 710 will come excruciatingly close to our Solar System in about a million years. An updated analysis suggests this star will come considerably closer than we thought, during which time it’s expected to spawn dangerous cometary swarms.

CellAge Campaign Q&A: Are You a For-Profit Company? |

Posted by in categories: biotech/medical, life extension

Non-profit research ultimately benefits for-profit companies and is an essential part of the development chain of any therapy.

Companies like Unity Biotech have taken non-profit research and are developing it for-profit, this is the only way that therapies will make it to market and pay for the huge costs involved in development. You may have concerns that our current crowdfunding project is with a for-profit company so here is CellAge to answer this question.

Classifying Aging As a Disease: The Role of Microbes

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

The body is under constant invasion by microbes so rejuvenation of the immune system and reduction of imflammation is a big priority for rejuvenation biotechnology.

Recent publications have proposed that aging should be classified as a disease (Bulterijs et al., 2015; Zhavoronkov and Bhullar, 2015; Zhavoronkov and Moskalev, 2016). The goal of this manuscript is not to dispute these claims, but rather to suggest that when classifying aging as a disease, it is important to include the contribution of microbes.

As recently as ~115 years ago, more than half of all deaths were caused by infectious diseases, including pneumonia, influenza, tuberculosis, gastrointestinal infections, and diphtheria (Jones et al., 2012). Since then, the establishment of public health departments that focused on improved sanitation and hygiene, and the introduction of antibiotics and vaccines allowed for a dramatic decrease in infectious disease-related mortality (Report, 1999). In 2010, the death rate for infectious diseases was reduced to 3% (Jones et al., 2012). Simultaneously, as infectious disease-related mortality rates have decreased, global lifespan has increased from ~30 to ~70 years (Riley, 2005).

Artificial leaf could make a medicinal mini-factory

Posted by in categories: biotech/medical, drones, internet, sustainability

Leaves are kind of like nature’s power plants, converting incoming sunlight into energy for the plant to thrive on. Inspired by the real thing, scientists have previously created artificial leaves that function in much the same way as their natural counterparts to produce electricity and even liquid fuels. Now a team at Eindhoven University of Technology (TU/e) is using a similar system to produce chemicals, which could one day lead to solar-powered “mini-factories” that can produce drugs, pesticides and other chemicals almost anywhere.

To mimic the light-capturing molecules in leaves, the researchers turned to luminescent solar concentrators (LSCs), materials seen in solar-harvesting window technology and used to catch and amplify laser beams carrying data in Facebook’s drone-mounted internet projec t. These LSCs absorb incoming light, convert it to specific wavelengths and then guide the photons to the edges of the device.

Solar System’s Next Close Encounter Will Be With Gliese 710, Say Astronomers

Posted by in category: asteroid/comet impacts

Gaia continues to reap dividends; per this new paper detailing a much closer solar system trajectory for Gliese 710, a sunlike star some 64 light years away in the constellation of Serpens.

Gliese 710, a star about half the size of our Sun, will rip through a portion of our solar system’s Oort Cloud of comets some 1.35 million years from now. In the process, it’s likely to dislodge a huge swath of long-period Earth-crossing comets.

Microsoft gives a detailed presentation on Holoportation at the ACM’s Special Interest Group on Computer-Human Interaction UIST ‘16 symposium

Posted by in categories: augmented reality, computing

In March this year Microsoft unveiled their new project – Holoportation, which they envision as the future of teleconferencing.

Holoportation is a new type of 3D capture technology that allows high quality 3D models of people to be reconstructed, compressed, and transmitted anywhere in the world in real-time. When combined with mixed reality displays such as HoloLens, this technology allows users to see and interact with remote participants in 3D as if they are actually present in their physical space.
