May 31st 2024, 14:50

A novel, human-inspired approach to training artificial intelligence (AI) systems to identify objects and navigate their surroundings could set the stage for the development of more advanced AI systems to explore extreme environments or distant worlds, according to new research.

May 30th 2024, 20:34

A new study has compared the amount of music and speech that children hear in infancy. Results showed that infants hear more spoken language than music, with the gap widening as the babies get older.

May 30th 2024, 18:22

During pregnancy, the effects of therapeutical doses of amphetamine have been investigated on birth outcomes in humans. However, a thorough investigation of the mechanisms underlying the long-term effects of embryonal exposure to addictive doses of amphetamine remains largely unexplored. Using a tiny worm, researchers have revealed the underlying mechanisms of embryonal exposure to methamphetamine (Meth) and amphetamines, a psychostimulant used to treat a variety of brain dysfunctions.

May 30th 2024, 18:22

New research sheds light on how individual neurons in the hippocampus of rats stabilize and tune spatial representations during periods of rest following the animals' first time running a maze, offering first proof of neuroplasticity during sleep.

May 30th 2024, 18:21

When we're told 'This coffee is hot' upon being served a familiar caffeinated beverage at our local diner or cafe, the message is clear. But what about when we're told 'This coffee is not hot'? Does that mean we think it's cold? Or room temperature? Or just warm? A team of scientists has now identified how our brains work to process phrases that include negation (i.e., 'not'), revealing that it mitigates rather than inverts meaning -- in other words, in our minds, negation merely reduces the temperature of our coffee and does not make it 'cold.'

May 30th 2024, 13:27

The formation of aggregates due to protein misfolding and resulting protein instability is associated with several diseases. Previous studies have shown the potential of sulfobetaine polymer, a zwitterionic polymer, to suppress protein aggregation. Now, researchers elucidate the mechanism underlying this process and show ways to optimize protein stabilization using these polymers. Going ahead, future therapies may be able to prevent or reverse diseases like Alzheimer's by building on the unique ability of zwitterionic polymers.

May 30th 2024, 13:27

A team of researchers have developed a new machine-learning method that detects hate speech on social media platforms with 88 per cent accuracy, saving employees from hundreds of hours of emotionally damaging work.

May 30th 2024, 13:26

Cultivating creativity in schools is vital for a future driven by artificial intelligence (AI). But while teachers embrace creativity as an essential 21st century skill, a lack of valid and reliable creativity tests means schools struggle to assess student achievement. Now, a new machine-learning model is providing teachers with access to high-quality, fit-for-purpose creativity tests, that can score assessments in a fraction of the time and a fraction of the cost.

May 29th 2024, 16:24

Researchers have, for the first time, visualized the full network of blood vessels across the cortex of awake mice, finding that blood vessels rhythmically expand and contract leading to 'waves' washing across the surface of the brain. These findings improve the understanding of how the brain receives blood, though the function of the waves remains a mystery.

May 29th 2024, 16:24

While older drugs for epilepsy, taken while pregnant, have been shown in previous research to affect the creative thinking of children, a new study finds no effects on creativity for children born to those taking newer epilepsy drugs.

May 29th 2024, 14:40

Interprofessional research study found that family caregivers of older adults living with dementia experienced a 15% drop in stress after a 9-week online peer support program.

May 28th 2024, 11:50

With generative artificial intelligence (GenAI) transforming the social interaction landscape in recent years, large language models (LLMs), which use deep-learning algorithms to train GenAI platforms to process language, have been put in the spotlight. A recent study found that LLMs perform more like the human brain when being trained in more similar ways as humans process language, which has brought important insights to brain studies and the development of AI models.
