Can having a stroke change your sleep?

People who have had a stroke may be more likely to sleep too much or too little compared to those without prior stroke, according to a new study. The study does not prove that stroke causes abnormal sleep; it only shows an association.

Researchers develop a stretchable, wearable device that lights up an LED using only the warmth of your skin

Researchers have developed a flexible, durable electronic prototype that can harvest energy from body heat and turn it into electricity that can be used to power small electronics, such as batteries, sensors or LEDs. This device is also resilient -- it still functions even after being pierced several times and then stretched 2,000 times.

Mirror, mirror, in my tank, who's the biggest fish of all?

Researchers have demonstrated that bluestreak cleaner wrasse (Labroides dimidiatus) checked their body size in a mirror before choosing whether to attack fish that were slightly larger or smaller than themselves, saying it was the first time for a non-human animal to be demonstrated to possess some mental states that are elements of private self-awareness.

Astronomers track bubbles on star's surface in most detailed video yet

Astronomers have captured images of a star other than the Sun in enough detail to track the motion of bubbling gas on its surface. The images of the star, R Doradus, were obtained in July and August 2023. They show giant, hot bubbles of gas, 75 times the size of the Sun, appearing on the surface and sinking back into the star's interior faster than expected.

Brain-wide decision-making dynamics discovered

Neuroscientists have revealed how sensory input is transformed into motor action across multiple brain regions in mice. The research shows that decision-making is a global process across the brain that is coordinated by learning. The findings could aid artificial intelligence research by providing insights into how to design more distributed neural networks.

Summer storms are stronger and more frequent over urban areas

Summer storms are generally more frequent, intense and concentrated over cities than over rural areas, according to new, detailed observations of eight cities and their surroundings. The results could change how city planners prepare for floods in their cities, especially as urban areas expand and as climate change alters global weather patterns.

Deserts' biggest threat? Flooding

A new study has found that the increase in soil erosion in coastal areas due to desertification is worsening flood impacts on Middle Eastern and North African port cities. The researchers focused their observations on the devastating 2023 floods in the city of Derna, Libya, which took the lives of more than 11,300 people and showed how the increase in soil erosion significantly contributed to the catastrophic toll of these unusual desert floods. The research was published almost a year after the deadly flood happened on the September 10, 2023.

Framing climate action as patriotic and status-quo friendly increases liberals' and conservatives' belief in climate change

A new psychology study shows that framing the need to address climate change as patriotic and as necessary to preserve the American 'way of life' can increase belief in climate change and support for pro-environmental policies among both groups.

Microwaving waste cooking oil into useful chemicals

Converting biomass such as waste cooking oil into useful chemicals through catalysis can help create a more sustainable chemical industry. However, conventional techniques require enormous energy and generate harmful chemicals. Moreover, such techniques reduce the lifetime of catalysts. Now, researchers reveal a zeolite catalyst that can be efficiently heated up using microwaves.

Falling for financial scams? It may signal early Alzheimer's disease

Findings from a new USC Dornsife study suggest that when older adults fall for financial scams, it could be an early warning sign of Alzheimer's disease. Researchers used MRI scans to find that older adults with thinner brain regions linked to memory and decision-making -- areas often affected early in Alzheimer's -- were more likely to be vulnerable to financial scams. The findings offer hope that financial vulnerability could be used as a simple screening tool to help identify early signs of cognitive decline, especially in people over 70.
