An atlas of the bumblebee brain
The buff-tailed bumblebee Bombus terrestris is one of the most common bumblebee species in Europe. It is not only active in nature as a pollinator—humans also use it in greenhouses and foil tunnels to get good harvests of tomatoes or strawberries......»»
Reading chemicals inside the brain with an aptamer/microelectronic fiber combination
A research group has developed a neural device that detects specific neurotransmitters in the brain with high sensitivity and selectivity by combining multifunctional fibers and DNA molecular probes. Details of the research were published in the jour.....»»
Study finds the brains of modern dog breeds are larger than those of ancient breeds
Modern dog breeds that are genetically more distant from wolves have a relatively larger brain size compared to ancient breeds that are thousands of years old, according to the findings of Hungarian and Swedish researchers. The increase in brain size.....»»
OpenAI peeks into the “black box” of neural networks with new research
"We do not understand" how LLMs work, admits OpenAI in quest to make them interpretable. Enlarge / An AI-generated image of robots looking inside an artificial brain. (credit: Stable Diffusion) On Tuesday, OpenAI publish.....»»
1 million images get stitched together to form an atlas of star birth
Stars are born in dense clouds of dust and gas called, adorably enough, stellar nurseries. Now, researchers have created an atlas of five of these regions......»»
“Sleep language” could enable communication during lucid dreams
Small muscle twitches could be the key to communicating during someone's REM sleep. Enlarge (credit: Westend61) Sleep is a semiconscious state, but there are neurons firing in the brain even when all seems quiet. Now bra.....»»
Can tiny brain tissues legally be a person? Researchers say not yet
Grown in labs, human brain organoids are cultivated from stem cells, feed on nutrient broth and serve as a model of human brain development in miniature. Their growth and structure mimic portions of real brains, allowing scientists to better investig.....»»
A new model for the evolution of honey bee brains
Researchers have proposed a new model for the evolution of higher brain functions and behaviors in the Hymenoptera order of insects. The team compared the Kenyon cells, a type of neuronal cell, in the mushroom bodies (a part of the insect brain invol.....»»
Giraffes, despite a relatively small brain, can handle statistics
This sort of behavior has previously only been seen in primates and parrots. Enlarge (credit: Arthur Morris) Reasoning about probabilities is something humans can't always manage especially well, but it's clearly a skill.....»»
Q&A: Using Prussian blue nanoparticles to diagnose and treat brain cancer
Meghan Hill is a graduate student in the Department of Biomedical Engineering at Michigan State University. Hill has won first place in MSU's Council of Graduate Student's 3-Minute Thesis Competition and represented MSU at the regional Midwestern Ass.....»»
Researchers complete first-ever mapping of human gut virus
Researchers at APC Microbiome Ireland (APC) have collaborated with scientists in the University of York to complete the first ever structural atlas of a crassvirus (also referred to as crassvirales, bacteriophage, crass-like phage)—the most abundan.....»»
The Modern World Is Aging Your Brain
In a remote part of the Amazon, anthropologists and neuroscientists are learning about life and health without an “embarrassment of riches.”.....»»
Machine learning model sheds light on how brains recognize communication sounds
In a paper published today in Communications Biology, auditory neuroscientists at the University of Pittsburgh describe a machine learning model that helps explain how the brain recognizes the meaning of communication sounds, such as animal calls or.....»»
AI plus MRI yields the ability to recognize what the mind is hearing
System can also reconstruct speech a person imagines. Enlarge (credit: Getty Images) We have various ways of seeing what the brain is up to, from low-resolution electrodes that track waves of activity that ripple across.....»»
Newly discovered electrical activity within cells could change the way researchers think about biological chemistry
The human body relies heavily on electrical charges. Lightning-like pulses of energy fly through the brain and nerves and most biological processes depend on electrical ions traveling across the membranes of each cell in our body......»»
Study suggests catalyst for human brain evolution
More than a million years ago, large chunks of the human genome were rearranged—a chance event during egg or sperm formation that led to the deletion, duplication, or reversal of sections of DNA. Those structural variants, researchers have now disc.....»»
Brain cells are starved of energy in autophagy dysfunction, new study finds
Neurodegeneration in brain cells may be happening when the natural cellular cleaning process malfunctions due to falling levels of a niacin-related coenzyme and leaves cells starved of energy, new research shows......»»
Brain circuits for locomotion evolved long before appendages and skeletons, finds new study
Hundreds of millions of years before the evolution of animals with segmented bodies, jointed skeletons or appendages, soft-bodied invertebrates like sea slugs ruled the seas. A new study finds parallels between the brain architecture that drives loco.....»»
Researcher: Social media scatters your brain, and then you buy stuff you don"t need
Social media can be mentally draining. And when mentally drained, you are more likely to be influenced by a high number of likes on posts—even to the point of clicking on ads for products you don't need or want—according to our recent experiments.....»»
How Our Team Overturned the 90-Year-Old Metaphor of a "Little Man" in the Brain Who Controls Movement
