US military successfully tests electrical brain stimulation to enhance staff skills

Posted by in categories: drones, military, neuroscience

US military scientists have used electrical brain stimulators to enhance mental skills of staff, in research that aims to boost the performance of air crews, drone operators and others in the armed forces’ most demanding roles.

The successful tests of the devices pave the way for servicemen and women to be wired up at critical times of duty, so that electrical pulses can be beamed into their brains to improve their effectiveness in high pressure situations.

The brain stimulation kits use five electrodes to send weak electric currents through the skull and into specific parts of the cortex. Previous studies have found evidence that by helping neurons to fire, these minor brain zaps can boost cognitive ability.

The future of science education and research at Stanford — By Taylor Kubota | Stanford News

Posted by in categories: education, mathematics, science

Sapp Center for Science Teaching and Learning, Old Chemistry Building

““The School of Humanities and Sciences is systematically re-thinking how we teach entry-level courses in the sciences,” said Richard P. Saller, dean of the School of Humanities and Sciences, during opening remarks for the event. “Half of all freshman enrollments in Stanford are in beginning-level sciences and math. We have tremendous impact by raising the level of teaching in these areas.””

Harvard Scientists Think They’ve Pinpointed the Physical Source of Consciousness

Posted by in categories: biotech/medical, neuroscience

Scientists have struggled for millennia to understand human consciousness — the awareness of one’s existence. Despite advances in neuroscience, we still don’t really know where it comes from, and how it arises.

But researchers think they might have finally figured out its physical origins, after pinpointing a network of three specific regions in the brain that appear to be crucial to consciousness.

It’s a pretty huge deal for our understanding of what it means to be human, and it could also help researchers find new treatments for patients in vegetative states.

Scientists Have Found a Bizarre Similarity Between Human Cells and Neutron Stars

Posted by in categories: biotech/medical, space

If you were to compare yourself to a neutron star, you probably wouldn’t find very many things in common. After all, neutron stars – celestial bodies with super strong magnetic fields – are made from collapsed star cores, lie light-years away from Earth, and don’t even watch Netflix.

But, according to new research, we share at least one similarity: the geometry of the matter that makes us.

Researchers have found that the ‘crust’ (or outer layers) of a neutron star has the same shape as our cellular membranes. This could mean that, despite being fundamentally different, both humans and neutron stars are constrained by the same geometry.

Great progress with the Winter Fundraiser and Patrons Challenge for SENS so far it looks like longevity research is really hotting up :)

Posted by in categories: biotech/medical, life extension

Hey folks, great news! The Patrons Challenge is going really well and we have already passed the halfway mark for new Patrons which is superb. Thanks to Reason and Josh Triplett who are doubling all new pledges made this year. So if you are interested in being a Patron this is a great time to join us.

Our Winter fundraiser has also reached almost 25k and is going great guns. The more we can raise the more research we can do and as this year has shown, some truly great results are starting to arrive for the SENS approach to treating age-related diseases.

Kardashev Scale: This Is What Life Will Look Like When We Harness the Energy of the Entire Universe

Posted by in categories: energy, physics, space

In Brief:

  • A Type IV civilization is a society that has managed to harness the energy of the entire universe.
  • To get here, we would need to tap into energy sources unknown to us using strange laws of physics (laws that may or may not exist).

To measure the level of a civilization’s advancement, the Kardashev scale focuses on the amount of energy that a civilization is able to harness. Obviously, the amount of power available to a civilization is linked to how widespread the civilization is (you can’t harness the power of a star if you are confined to your home planet, and you certainly can’t harness the power of a galaxy if you can’t even get out of your solar system).

Close to absolute zero, electrons exhibit their quantum nature

Posted by in categories: particle physics, quantum physics

What would happen if an electric current no longer flowed, but trickled instead? This was the question investigated by researchers working with Christian Ast at the Max Planck Institute for Solid State Research. Their investigation involved cooling their scanning tunnelling microscope down to a fifteen thousandth of a degree above absolute zero. At these extremely low temperatures, the electrons reveal their quantum nature. The electric current is therefore a granular medium, consisting of individual particles. The electrons trickle through a conductor like grains of sand in an hourglass, a phenomenon that can be explained with the aid of quantum electrodynamics.

Flowing water from a tap feels like a homogeneous medium — it is impossible to distinguish between the individual water molecules. Exactly the same thing is true about electric current. So many electrons flow in a conventional cable that the current appears to be homogeneous. Although it is not possible to distinguish individual electrons, quantum mechanics says they should exist. So how do they behave? Under which conditions does the current not flow like water through a tap, but rather trickles like sand in an hourglass?

The hourglass analogy is very appropriate for the scanning tunnelling microscope, where a thin, pointed tip scans across the surface of a sample without actually touching it. A tiny current flows nevertheless, as there is a slight probability that electrons “tunnel” from the pointed tip into the sample. This tunnelling current is an exponential function of the separation, which is why the pointed tip is located only a few Ångström (a ten millionth of a millimetre) above the sample.
