When you get in the car to see your significant other for dinner, your brain’s reward center is likely flooded with dopamine, a hormone also associated with cravings for sugar, nicotine, and cocaine. This rush of dopamine motivates you to navigate through traffic to maintain that special connection. However, if the dinner is with just a work colleague, this intense flood of dopamine may be reduced to a mere trickle, according to recent research conducted by neuroscientists at the University of Colorado Boulder.

“What we have found, essentially, is a biological signature of desire that helps us explain why we want to be with some people more than other people,” said senior author Zoe Donaldson, associate professor of behavioral neuroscience at CU Boulder.

Scientific investigations on the ISS’s latest resupply mission include advancements in 3D metal printing, semiconductor manufacturing, reentry thermal protection, robotic surgery, and cartilage tissue regeneration. These studies aim to enhance space mission sustainability and have significant implications for Earth-based technologies and health care.

Tests of a 3D metal printer, semiconductor manufacturing, and thermal protection systems for reentry to Earth’s atmosphere are among the scientific investigations that NASA and international partners are launching to the International Space Station on Northrop Grumman’s 20th commercial resupply services mission. The company’s Cygnus cargo spacecraft is scheduled to launch on a SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station in Florida by late January.

SynapShot, developed by an international research team, marks a major advancement in neuroscience by enabling real-time, live observation of synaptic changes in the brain.

The human brain contains approximately 86 billion neurons and 600 trillion synapses that exchange signals between the neurons to help us control the various functions of the brain including cognition, emotion, and memory. Interestingly, the number of synapses decrease with age or as a result of diseases like Alzheimer’s, and research on synapses thus attracts a lot of attention. However, limitations have existed in observing the dynamics of synapse structures in real-time.

Scientists have developed “quantum ping-pong”: Using a special lens, two atoms can be made to bounce a single photon back and forth with high precision.

Atoms can absorb and reemit light — this is an everyday phenomenon. In most cases, however, an atom emits a light particle in all possible directions — recapturing this photon is therefore quite hard.

We’re reading more than ever before – but much of it is on screens rather than physical books. Is it changing the way our brains work? Reading books has so many physical, emotional and economic benefits — here’s why how we read might be more important than what or how much we read.
