While 'peer pressure' is often linked to experiences of children or teenagers, researchers say young adults continue to succumb to similar pressures of social conformity in everyday situations.

Scientists are taking a more detailed look at how children's language development is influenced by the number of people in their households, evaluating the impact of the adult-to-child ratio within each residence. American demographics have shifted significantly in the last 40 years, with many more children living in homes with extended families. Greater household density -- the ratio of people to bedrooms in a home -- has been shown to have a negative effect on children's language development.

A galaxy that suddenly stopped forming new stars more than 13 billion years ago has been observed by astronomers. Using the James Webb Space Telescope, astronomers have spotted a 'dead' galaxy when the universe was just 700 million years old, the oldest such galaxy ever observed.

Researchers have uncovered a strikingly similar suite of changes in gene activity in brain tissue from people with schizophrenia and from older adults. These changes suggest a common biological basis for the cognitive impairment often seen in people with schizophrenia and in the elderly.

Bumblebees successfully learned a two-step puzzle box task through social observation. This task was too complex for individual bees to learn on their own. Observing trained demonstrator bees performing the first unrewarded step was crucial for successful social learning. Individual bees failed to solve the puzzle without previous demonstration, despite extensive exposure.

A research team has examined the link between adverse childhood experiences and the risk of mental health problems later in life. The researchers have found that the risk of suffering from mental illness later in life among those experiencing significant adversity in childhood can be partly explained by factors shared by family members, such as genetics and environment.

Some of our genes can be expressed or silenced depending on whether we inherited them from our mother or our father. The mechanism behind this phenomenon, known as genomic imprinting, is determined by DNA modifications during egg and sperm production.

'Random DNA' is naturally active in the one-celled fungi yeast, while such DNA is turned off as its natural state in mammalian cells, despite their having a common ancestor a billion years ago and the same basic molecular machinery, a new study finds.

Precision timing and synchronization are crucial for navigation, communication and radar systems. Scientists have built compact chips capable of converting light into microwaves, which could improve these systems. This technology shrinks a tabletop system into a chip-sized format, reducing power usage and making it more applicable for use in everyday devices.

Epigenetic changes play important roles in cancer, metabolic and aging-related diseases, but also during loss of resilience as they cause the genetic material to be incorrectly interpreted in affected cells. A major study now provides important new insights into how complex epigenetic modification signatures regulate the genome. This study will pave the way for new treatments of diseases caused by faulty epigenetic machineries.

A link between abnormal blood levels of amyloid -- a protein associated with Alzheimer's disease -- and subtle changes in brain microstructures on a type of MRI could lead to a new way to detect Alzheimer's earlier in people with no clinical signs.
