Cellular powerhouse may also propel aging

Posted by in categories: biotech/medical, life extension

Mitochondria — the structures within cells mostly known for converting nutrients into usable energy — may play a larger and more direct role in the aging process than previously thought, according to USC Leonard Davis School of Gerontology Assistant Professor David Lee.

In addition to powering cells, mitochondria serve important roles in coordinating metabolism, Lee said. And evidence has shown that mitochondria — which have their own smaller genome separate from the larger collection of genes in a cell’s nucleus — lose function and accrue DNA damage during the aging process, reflecting a role in aging.

In trying to determine how the mitochondria are involved in aging, many researchers have studied the signals sent from the nucleus to the mitochondria and how they change with age. However, Lee theorizes that communication between the cell’s powerhouse and its control center may be taking place in both directions, with signaling molecules originally coded in the mitochondrial DNA regulating the nucleus and causing changes that affect key cellular factors of aging, such as metabolism.

IF solid metallic hydrogen is a really good room temperature superconductor

Posted by in categories: materials, physics

On October 5th 2016, Ranga Dias and Isaac F. Silvera of Lyman Laboratory of Physics, Harvard University released the first experimental evidence that solid metallic hydrogen has been synthesized in the laboratory.

It took 495 GPa pressure to create. The sample is being held in the cryostat in liquid nitrogen.

If as predicted by theory the metallic hydrogen remains metastable when the extreme pressure is removed then the world will eventually be greatly changed.

400,000 Bots Are Posting Political Tweets About The Election, And They Have Influence

Posted by in category: robotics/AI

If your political conversations on social media seem mechanical and predictable, it might be because you are debating with a robot.

A study published the day before the election found an estimated 400,000 bots operating on Twitter that were tweeting—and being retweeted—at a remarkable pace, generating nearly 20 percent of all election-related messages.

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.

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.
