A significant portion of an organism’s genome is non-coding; that is, it does not carry information to make proteins. Part of the non-coding DNA is transcribed into functional non-coding RNA molecules (e.g., transfer RNA, ribosomal RNA and regulatory RNA). Other functions of non-coding DNA include transcriptional and translational regulation of protein coding sequences, nuclear scaffold […]
Mental wandering, sometimes referred to as off-task thinking or, colloquially, going on autopilot, is the experience of thoughts not staying on a single topic, but jumping without control from one thing to another. This is particularly striking when we are engaged in a task that requires focus. A common place for mental wandering is when […]
COVID-19 worsens the already existing social difficulties for older adults and the disabled involved in long-term care services and supports; i.e., nursing homes, skilled nursing facilities, and home and community-based services . A hug is a form of non-verbal communication. It can indicate familiarity, love, affection, friendship, brotherhood, or sympathy. We use it when we […]
Williams syndrome (WS) was first described in 1961 by New Zealand cardiologist John Williams. It is mostly caused by the microdeletion 7q11.23, a loss of a fragment of genetic material on chromosome 7. It is usually a “de novo” mutation, that is, it is not inherited from the parents, but rather arises in that child […]
From advertising to the workplace, it is often assumed that men and women are fundamentally different – from Mars and Venus, respectively. Of course, we all know people who are more androgynous, having a mix of personality traits that are stereotypically considered to be male or female. Importantly, such “psychological androgyny” has long been associated […]
The intranasal route is a rapid, efficient and direct way for different biological agents, small molecules, drugs and chemical compounds to reach the brain. It seems amazing, but people that snort a line of coke already knew that… To date, its mechanism of diffusion is believed to be using either olfactory nerve tracts or dense […]
Depression is a psychiatric and psychological diagnosis that describes a temporary or permanent mood disorder characterized by feelings of dejection, unhappiness and guilt. Depressed people show a low mood and an aversion to activity and are characterized by sadness, difficulty thinking and concentrating, and a significant increase or decrease in appetite and time spent sleeping […]
Going through a break up is kind of traumatic. We all have felt it sometime, not only your heart is broken but your brain feels like out of sync and incapable of proper functioning. Well, this is not just an impression, new research has found there is a relationship between a broken heart and a […]
To date, more than 50 million people have been infected with the new coronavirus, SARS-CoV-2, and more than 1,2 million have died. It is a global problem, affecting everyone, but we are still learning how it infects, how it behaves, what causes harm to humans. The virus is spread by the droplets produced by an […]
How can we experience a sensation that is not real? How to mimic a sensory stimulus in its absence? How to smell a smell when there is none there? By activating certain neurons, it seems. A group of researchers at New York University’s Grossman School of Medicine have recently published an article in Science […]
