Researchers have leveraged a complex web of data to test a hypothesis: That structural racism is associated with resources and structures at the neighborhood level that are closely associated with poor health. What they found in an analysis of highly localized, community level data illustrates how racism is deeply interrelated with poor health outcomes.
Light color is less important for the internal clock than originally thought
Light in the evening is thought to be bad for sleep. However, does the color of the light play a role? Researchers compared the influence of different light colors on the human body. The researchers' findings contradict the results of a previous study in mice.
Researchers map how measles virus spreads in human brain
Researchers mapped how the measles virus mutated and spread in the brain of a person who succumbed to a rare, lethal brain disease. New cases of this disease, which is a complication of the measles virus, may occur as measles reemerges among the unvaccinated, say researchers.
New tool unifies single-cell data
A new methodology that allows for the categorization and organization of single-cell data has been launched. It can be used to create a harmonized dataset for the study of human health and disease.
A research team has uncovered a previously undetected mechanism in mice -- starring the genetic molecule RNA -- that could explain how each sensory cell, or neuron, in mammalian noses becomes tailored to detect a specific odor chemical.
New brain-like transistor mimics human intelligence
Researchers develop transistor that simultaneously processes and stores information like the human brain. Transistor goes beyond categorization tasks to perform associative learning. Transistor identified similar patterns, even when given imperfect input. Previous similar devices could only operate at cryogenic temperatures; new transistor operates at room temperature, making it more practical.
Integrating research and clinical care to uncover secrets of brain development
A subset of neurons related to memory and neuroplasticity continue to migrate into the brain through toddlerhood.
Meet 'Coscientist,' your AI lab partner
An artificial intelligence-driven system has autonomously learned about certain Nobel Prize-winning chemical reactions and designed a successful laboratory procedure to make them. The AI did so in just a few minutes and correctly on its first attempt. According to the authors, this is the first time that a non-organic intelligence planned, designed and executed this complex reaction that was invented by humans.
Cells of the future: A key to reprogramming cell identities
The intricate process of duplicating genetic information, referred to as DNA replication, lies at the heart of the transmission of life from one cell to another and from one organism to the next. This happens by not just simply copying the genetic information; a well-orchestrated sequence of molecular events has to happen at the right time. Scientists have recently uncovered a fascinating aspect of this process known as 'replication timing' (RT) and how special this is when life commences.
Study unveils a role of mitochondria in dietary fat processing
Researchers discover a new mechanism controlling the uptake of lipids from digested food.
