Researchers at the University of Arizona are developing a fresh approach to cybersecurity modeled on the human central nervous system. The new method will aim to detect and neutralize cyber-threats in their earliest stages before they have a chance to do any serious damage. Inspiration for the project came from human biological responses; for example, how the body's immune system fights a virus and how a person will instinctively pull their fingers away from a burning hot surface before their brain has even received the message that the body is at risk of harm.
Prime factors in the changing structure of the face include a growing brain and adaptations to respiratory and energy demands, but most importantly, changes in the jaw, teeth, and face responded to shifts in diet and feeding behavior. We are, or we evolved to be, what we eat.
The human brain can unconsciously respond to changes in Earth's magnetic fields, according to a team of geoscientists and neurobiologists.
Studies suggest a connection between mental and physical effort: both require cognitive control. The reason such control is essential in demanding athletic training, they suggest, is that to maintain physical effort and reach a distant goal requires cognitive control.
Spending at least two hours a week in nature may be a crucial threshold for promoting health and wellbeing, according to a new large-scale study.
Researchers from the University of Copenhagen have learned that the effect of exercise may differ depending on the time of day it is performed. In mice they demonstrate that exercise in the morning results in an increased metabolic response in skeletal muscle, while exercise later in the day increases energy expenditure for an extended period of time.
Finding suggests that mobile phones are potentially increasingly affecting aspects of daytime functioning due to lack of sleep and increasing dereliction of responsibilities.
Researchers are finding that brain changes that occur after a single workout are predictive of what happens with sustained physical training over time.
Having raised levels of inflammation in your body, which is generally caused by the immune system’s response to infection or injury, can skew your judgment to focus more on present rewards, and on instant gratification. If further research backs this up, there could be wide-ranging implications not only for understanding why some people are more impulsive than others, but even for treating substance abuse. This adds to the growing body of research demonstrating that the internal, physiological condition of the body plays an important role in modulating decision-making and behaviour.
Just 16 minutes shaved off your regular sleep routine can dramatically impact job performance the next day. A new study shows that slight dip of sleep causes workers to have poor judgement and fall off-task. Workplaces need to make more efforts to promote their employees' sleep. Good sleepers may be better performers at work due to greater ability to stay focused an on-task with fewer errors and interpersonal conflicts.
Study highlights that uninterrupted sitting should be avoided to maintain optimal cognition across the day, and that moderate-intensity exercise such as a brisk walk should be encouraged for the daily maintenance of brain health.
Study shows that how we feel in our close relationships is influenced by more than just our shared experiences with our partners over time.
Study provides a mechanism for sex-based differences in social behaviors and suggests that differences in androgen and endocannabinoid signaling may contribute to individual differences in brain development and thus behavioral differences among people.
Testosterone’s effects on human aggression are likely AR [androgen receptor] dependent.
Musical training produces lasting improvements to a cognitive mechanism that helps individuals be more attentive and less likely to be distracted by irrelevant stimuli while performing demanding tasks. Notably, the more years of training musicians have, the more efficient they are at controlling their attention.
sleep duration and satisfaction is decreased up to six years after giving birth for both parents.
The part of the brain responsible for the fight-or-flight response also plays a key role in unconsciously processing a face’s trustworthiness – in a matter of milliseconds. The amygdala is processing untrustworthiness as if it were a threat. In 33 milliseconds we decide whether or not we can trust someone. Something that someone unconsciously decides in an instant could take a long time to overcome.
We notice a voice much faster when it is considered threatening than when it is perceived as normal or happy. Our attention is more focused on threatening voices to enable us to clearly recognize the location of the potential threat.
Social status determined how individual macaques responded to a key stress hormone, glucocorticoid.
The potentially fatal effects of blows to the chest are believed to be the result of rapid strains that adversely interfere with the transmission of electrical impulses thereby causing disruption of the heartbeat. The same interactions are thought to underlie the rescue of patients in cardiac arrest by an appropriately timed thump to the chest.
