Controlling the Brain with Light to Reactivate Lost Memories

The key mol­e­cule of opto­ge­net­ics is a light-sensitive pro­tein called chan­nel­rhodopsin, which is extract­ed from green algae. Scientists can insert chan­nel­rhodopsin into mem­o­ry cells. Subsequently, sci­en­tists can even acti­vate the­se with blue light which they deliv­er deep inside the brain with optic fibers. 

Machines That Can Read Human Emotions

The face is a con­stant flow of facial expres­sions. We react and emote to exter­nal stim­uli all the time. And it is exact­ly this flow of expres­sions that is the observ­able win­dow to our inner self. Our emo­tions, our inten­tions, atti­tudes, moods. Why is this impor­tant? Because we can use it in a very wide vari­ety of appli­ca­tions.

Realizing a Brain on a Chip

If we want to con­tin­ue increas­ing the per­for­mance of our com­put­ers, we need to rethink the way we com­pute. And our brains are won­der­ful proof that impres­sive com­pu­ta­tions can be car­ried out with a very low pow­er bud­get.

Traditional Medicine Reimagined Through Modern Systems Biology

Why are nat­u­ral com­pounds bet­ter than syn­thet­ic chem­i­cals to treat dis­eases? We have inten­sive­ly ana­lyzed all those known com­pounds in the nat­u­ral prod­ucts, and found that the­se com­pounds have high­er sim­i­lar­i­ty, espe­cial­ly struc­tural sim­i­lar­i­ty, to human metabo­lites.

Applying Neuroscientific Findings to Enduring Social Problems

When low­er pri­mates form a hier­ar­chy, those at the bot­tom under­go a change in their dopamine sys­tem. This makes them more like­ly to con­sume drugs in an addic­tive fash­ion. Now, if this turns out to be true of our species, that would mean that human beings are par­tic­u­lar­ly vul­ner­a­ble if they’re in some way dom­i­nat­ed or don’t have any pow­er.

Reimagining Everyday Devices as Information-Delivery Systems

What we’re try­ing to think about now is, take the sort of ven­er­a­ble light bulb and recast it as a com­pu­ta­tion­al appli­ance. So, how do we take some­thing that’s been so remark­ably suc­cess­ful and infuse it with com­pu­ta­tion­al abil­i­ties?

Looking to Ants to Better Understand Collective Behaviour

How can we extend what we are learn­ing about how sim­ple local inter­ac­tions in ant colonies or in brains, in the aggre­gate, pro­duce the col­lec­tive behav­ior of the group and the way that it responds to chang­ing con­di­tions? How can we extend what we’re learn­ing about col­lec­tive behav­ior in oth­er sys­tems to begin think­ing about col­lec­tive behav­ior in human social orga­ni­za­tions?

Manufacturing Dreams

We used to think that sleep is a pas­sive process caused by reduced sen­so­ry stim­u­la­tion so that our nor­mal men­tal and phys­i­cal activ­i­ties can shut down. We held this belief since the time of Aristotle, and per­haps even before that. But now we know that this idea is com­plete­ly wrong.

Data & Society Databite #41: Ifeoma Ajunwa on Genetic Coercion

The mythol­o­gy of genet­ic coer­cion is thoughts that genet­ic data, espe­cial­ly large-scale genet­ic data­bas­es, have the abil­i­ty to pin­point cer­tain risk of dis­ease. They provide agen­cy to act to pre­vent such dis­ease, and it can be used to cre­ate accu­rate per­son­al­ized treat­ment for dis­ease, and it should also be entrust­ed with the author­i­ty to dic­tate the mod­i­fi­ca­tion of the genome for future gen­er­a­tions.

Safiya Noble at Biased Data

I often try to tell peo­ple that Google is not pro­vid­ing infor­ma­tion retrieval algo­rithms, it’s pro­vid­ing adver­tis­ing algo­rithms. And that is a very impor­tant dis­tinc­tion when we think about what kind of infor­ma­tion is avail­able in the­se corporate-controlled spaces.
