Are you an avid supporter of aging research and a keen longevity activist?
The Biogerontology Research Foundation is offering select summer internships for talented individuals. You’d join a passionate and supportive team in researching diagnostic, prognostic, and therapeutic strategies; advising a panel of investors in developing a roadmap to promote longevity science and related technologies across the globe.
The advertised positions are 3 month internships, with the possibility of continuing afterwards. Free accommodation will be provided for in London, alongside a negotiable salary.
The Biogerontology Research Foundation is a UK based think tank dedicated to aging research and accelerating its application worldwide.
“May you live in interesting times,” resonates with many involved in the metal 3D printing industry, an ironic phrase regarded by some as a curse. Magnus René, CEO of the Arcam Group AB, might one of the last to agree. In the 3D metal printing market Arcam are unique. Holding propriety Electron Beam Melting (EBM) patents the company is at the forefront of cutting edge industries such as aerospace and medicine. I asked Arcam’s CEO about some of these developments.
René compares today’s additive manufacturing landscape to an earlier career experience in another industry at the frontier of technology.
“I was with a company that developed and released the [semiconductor] printers that are used still to this day for manufacture. Those were also interesting times, we really felt that we were changing the way things were manufactured.”

Fog, blizzards, gusts of wind — poor weather can often make the operation of rescue helicopters a highly risky business, and sometimes even impossible. A new helmet-mounted display, developed by researchers at the Technical University of Munich (TUM), may in the future be able to help pilots detect hazards at an early stage, even when their visibility is severely impaired: the information required to do this is created in an on-board computer and imported into digital eye glasses.
A new study has shown that this augmented reality improves the performance of pilots.
Thick clouds hang over the Tegernsee. The range of sight is just a few hundred meters. Under normal circumstances, a helicopter would not be allowed to take off in such weather — the danger that the pilot would not be able to react in time to a construction crane, a power line or a mountain would be too great.
A team of researchers led by professor Jean-Christophe Marine (VIB-KU Leuven) has identified NEAT1, a non-coding RNA, as a potential therapeutic target in the fight against cancer. In collaboration with the Cédric Blanpain lab (ULB), VIB researchers have shown that NEAT1 plays an important role in the survival of highly dividing cells — and in particular of cancer cells. These findings can help develop new drugs that target NEAT1, in order to kill cancer cells more effectively.
As a non-coding RNA, NEAT1 is not translated into a protein. It does however contribute to the formation of so-called ‘paraspeckles’, subnuclear particles that can be found in the cell nuclei of cancer cells. The function of these particles has remained obscure. Although highly conserved through evolution, NEAT1 appears to be dispensable for normal embryonic development and adult life as mice lacking NEAT1 are viable and healthy.

Get ready.
China will launch the world’s first quantum satellite next month to demonstrate a series of advanced technologies such as hacker-proof communications and quantum teleportation.
Ground testing and quality checks on the satellite had finished at the Chinese Academy of Sciences, and it would depart for the Jiuquan Satellite Launch Centre in Inner Mongolia early this month for a launch aboard a Long March 2D rocket in the middle of next month, according to a report on the central government’s website posted on Friday.

Scientists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a possible secret to dramatically boosting the efficiency of perovskite solar cells hidden in the nanoscale peaks and valleys of the crystalline material.
Solar cells made from compounds that have the crystal structure of the mineral perovskite have captured scientists’ imaginations. They’re inexpensive and easy to fabricate, like organic solar cells. Even more intriguing, the efficiency at which perovskite solar cells convert photons to electricity has increased more rapidly than any other material to date, starting at three percent in 2009 — when researchers first began exploring the material’s photovoltaic capabilities — to 22 percent today. This is in the ballpark of the efficiency of silicon solar cells.
Now, as reported online July 4, 2016 in the journal Nature Energy, a team of scientists from the Molecular Foundry and the Joint Center for Artificial Photosynthesis, both at Berkeley Lab, found a surprising characteristic of a perovskite solar cell that could be exploited for even higher efficiencies, possibly up to 31 percent.

A team of neuroscientists at the Champalimaud Centre for the Unknown, in Lisbon, has been able to map single neural connections over long distances in the brain. “These are the first measurements of neural inputs between local circuits and faraway sites”, says Leopoldo Petreanu, who led the research. In doing so, Petreanu and co-authors Nicolás Morgenstern and Jacques Bourg have also discovered that the wiring of the brain is more complex than previously thought. Their results have been published in the journal Nature Neuroscience.
“We want to understand the structure of the brain, but the wiring diagram we have of the brain is still very rough”, says Petreanu. “Except at the local level, we don’t know how individual axons [the fibers projected by neurons] connect.”
Thanks to a novel technique involving neural stimulation with laser light developed at their lab, the scientists were able to track the activity of individual axons, in the mouse brain, between a brain structure called the thalamus and the part of the visual cortex which receives, by way of the thalamus, the visual stimuli from the retinas.
Way cool.
Ideally, injectable or implantable medical devices should not only be small and electrically functional, they should be soft, like the body tissues with which they interact. Scientists from two UChicago labs set out to see if they could design a material with all three of those properties.
The material they came up with, published online June 27, 2016, in Nature Materials, forms the basis of an ingenious light-activated injectable device that could eventually be used to stimulate nerve cells and manipulate the behavior of muscles and organs.
