Human and Neanderthal brains have a surprising "youthful" quality in common, new research finds
Many believe our particularly large brain is what makes us human—but is there more to it? The brain's shape, as well as the shapes of its component parts (lobes) may also be important......»»
How humans got a new gene that makes our brains larger
Somewhere between chimps and us, an RNA started producing a useful protein. Enlarge / Building a bigger brain requires new genes, not a workout. (credit: OsakaWayne Studios) On the DNA level, there's not much to distingu.....»»
Telling left from right: Cilia as cellular force sensors during embryogenesis
Although the human body is externally symmetric across the left-right axis, there are remarkable left-right asymmetries in the shape and positioning of most internal organs, including the heart, lungs, liver, stomach, and brain......»»
Lost puzzle piece involved in gene regulation revealed in search that began in water-loving, one-celled organism
After an intrepid, decade-long search, Johns Hopkins Medicine scientists say they have found a new role for a pair of enzymes that regulate genome function and, when missing or mutated, are linked to diseases such as brain tumors, blood cancers and K.....»»
The lenses of fishes" eyes record their lifetime exposure to toxic mercury, new research finds
Mercury pollution is a global threat to human health, especially to unborn babies and young children. Exposure to methylmercury, a type that forms when mercury washes into lakes and streams, can harm children's brain development and cause symptoms in.....»»
Your Brain Uses Calculus to Control Fast Movements
To sharpen its command over precise maneuvers, the brain uses comparisons between control signals—not the signals themselves......»»

Elon Musk"s Neuralink shows brain implant prototype and robotic surgeon during recruiting event
Elon Musk — the SpaceX founder, Tesla CEO, and, most recently, Twitter owner — hosted a flashy event on Wednesday night for yet another one of his companies: Neuralink, the startup proposing implants that connect your brain to a computer......»»
Organic cation transporters: Research into their structure facilitates targeted development of new drugs
Monoamines are neurotransmitters in the central and peripheral nervous systems and they also transmit signals between cells and the brain. This transmission is followed by their reuptake into the cells by means of transporters. While the specific mon.....»»

Team creates nano-magnets that could restore damaged nerve cells
Neurons are the fundamental units of the brain and nervous system, the cells responsible for receiving sensory input from the external world, for sending motor commands to our muscles, and for transforming and relaying the electrical signals at every.....»»
Scientists provide structural insights into NaV1.7 modulation by inhibitors, to block pain signals to the brain
Chronic pain is an extremely common condition that affects about 20% of the general population. Given the shortage of effective and non-addictive analgesics, new anti-pain drugs are eagerly awaited. Voltage-gated sodium channel NaV1.7 plays an essent.....»»

Human evolution: Brain, gut and immune system were fine-tuned after split from common ancestor of chimpanzees
A team of Duke researchers has identified a group of human DNA sequences driving changes in brain development, digestion and immunity that seem to have evolved rapidly after our family line split from that of the chimpanzees, but before we split with.....»»
Artificial neural networks learn better when they spend time not learning at all
Depending on age, humans need 7 to 13 hours of sleep per 24 hours. During this time, a lot happens: Heart rate, breathing and metabolism ebb and flow; hormone levels adjust; the body relaxes. Not so much in the brain......»»
