Read. Study topics I don’t know about. Learn new skills and try out new experiences. Travel to different places I haven't visited before.

scitechdaily.com New Hope in Alzheimer’s Fight: Researchers Identify Unique Early Biomarker
This molecule is directly associated with the expression of the cellular prion protein located on the surface of nerve cells. The research, conducted by the Institute for Bioengineering of Catalonia, paves the way for early detection of Alzheimer's disease. A new study conducted by the Molecular
Clinical relevance of miRNAs as biomarkers is growing due to their stability and detection in biofluids. This study has identified miR-519a-3p as a potential early biomarker for Alzheimer’s, linked to prion protein expression. This molecule is directly associated with the expression of the cellular prion protein located on the surface of nerve cells. miR-519a-3p may potentially be used as a biomarker of preclinical stages of the disease.

Oh this is partly how listening to music works for me. I'll be listening to some particular songs in the moment repeatedly, get fed up of either all of them at once or one by one, then just stop listening to those that I get fed up of. I'll then again listen to music when I again feel like listening to some particular music.
This is not directly related, but one reason I stop myself from binge watching TV shows is that if I end up watching too many episodes of a TV series at one go it can end up ruining the show for me, regardless of how great it may be, because watching too many episodes at one go makes me so fed up of the show that I don’t feel like watching it anymore. Binge watching almost ruined Breaking Bad for me; since then I make it a point to never watch more than 2 episodes of a show in a day. I generally restrict myself to one episode per day.
www.nytimes.com The Textbooks Were Wrong About How Your Tongue Works
The perception of taste is remarkably complex, not only on the tongue but in organs throughout the body.
The perception of taste is remarkably complex, not only on the tongue but in organs throughout the body.
The idea that specific tastes are confined to certain areas of the tongue is a myth that “persists in the collective consciousness despite decades of research debunking it.” Also wrong: the notion that taste is limited to the mouth.
Thanks for sharing
Love the smell of n-hexane and pet ether (worked in a chemistry lab). Though don't like the smell of gasoline. I kind of also like the smell of chlorinated water. Also chloroform, though not as much as n-hexane.

Kind of had the same thought!
ACC is mainly studied for its role in cognition and emotion. In the article linked it's mentioned >The ACC is one of the higher-order cortical regions that have been extensively studied for cognitive and emotional brain functions, but have been understudied for brain disease-related sensory abnormalities.> I also found another article on the role of ACC in cognition and emotion: https://neuro.psychiatryonline.org/doi/full/10.1176/jnp.23.2.jnp121

Oh yeah one of my favourite shows.
In my case I've found the need to use Google for local searches, and certain very specific searches (one example is journal impact factors). In a lot of other cases, DDG has actually given me better results - I was getting fed up with some of the crappy results I was getting using Google, which prompted me to try out and eventually shift to DDG.
scitechdaily.com Scientists Pinpoint Main Cause of Sensory Hypersensitivity in Autism
Sensory hypersensitivity in mice with Grin2b mutations is associated with hyperactivity in the anterior cingulate cortex and increased connectivity throughout the brain. A research team led by Director Kim Eunjoon of the Center for Synaptic Brain Dysfunctions and Director Kim Seong-Gi of the Center
This study has identified the anterior cingulate cortex (ACC) as a key area in the brain responsible for sensory hypersensitivity in autism spectrum disorders. Utilizing a mouse model with a Grin2b gene mutation, heightened neural activity and connectivity in the ACC was observed. Suppressing this hyperactivity normalized the sensory hypersensitivity, offering new insights into treatment options

Technology that enables researchers to interpret brain signals could one day allow people to talk using only their thoughts.
Brain-machine interfaces implanted in the participants of this study in the supramarginal gyrus (SMG) and primary somatosensory cortex (S1) were successfully able to decode both internally spoken and vocalized words.
www.nature.com Human embryos embrace asymmetry to form the body
The cells generated by the very first division of the fertilized egg make a lopsided contribution to the body’s organs and tissues.
This study performed lineage tracing of live human embryos from the first cleavage division until the blastocyst stage and discovered that the majority of cells in the EPI, the future human body, originate from one of the two cells in most embryos. The first blastomere to divide at the 2-cell stage has a higher likelihood to generate the first, and more, internalized cells at the 8-to-16-cell stage.

bigthink.com The scientific story behind the timeline of our Universe
From the earliest stages of the hot Big Bang (and even before) to our dark energy-dominated present, how and when did the Universe grow up?
An interesting article on the time line of the universe.
The Universe passed through many epochs, from free quarks and gluons to stable protons and neutrons to neutral atoms to stars, galaxies, planets, and more. The precise time at which these various epochs occurred, including the (current) dark energy-dominated era, can be pinpointed with precision. Here’s how we know.
Oh please do continue the good work! Very cute cat.

scitechdaily.com Engineering Life: Chemists Have Created the Functional Synthetic Cells That Act Like Real Ones
Researchers employ cutting-edge methods to create functional cells, closing the divide between synthetic and biological materials. In a new study published in Nature Chemistry, UNC-Chapel Hill researcher Ronit Freeman and her colleagues describe the steps they took to manipulate DNA and proteins —
The engineering of artificial cells requires a reconfigurable cytoskeleton that can organize at distinct locations and dynamically modulate its structural and mechanical properties. This study combines peptide self-assembly with DNA programmability to realize a synthetic cytoskeleton in droplets showing that programmable peptide–DNA nanotechnology approach is a powerful platform towards the construction of functional, fully artificial cells.

scitechdaily.com Decoding the Origin of Life: Scientists Solve Early Earth RNA Puzzle

This study reveals how life’s complexity could originate from simple RNA molecules on early Earth. Through experiments demonstrating RNA’s recycling and replication abilities under conditions such as low salinity and high pH, the research suggests life could emerge from minimal molecular sets in environments akin to volcanic islands. This means that an RNA world could arise without the prior necessity for long complex sequences.
