Adverse childhood experiences such as poverty, abuse and neglect have been linked to poor mental and physical health outcomes in adulthood. However, characterizing early experiences only in terms of extreme stressors fails to capture the full spectrum of childhood for most people. In fact, a recent study by Lee et al. (2015) in Psychology and Aging suggests that looking at early adversity only tells part of the story.

Okazaki, Japan - A person in love gazes longingly and attentively at the object of his or her desire. When we want to grab another person's attention, we look directly into their eyes. Why do we behave this way? What happens during our gazing?
Researchers at the National Institute of Physiological Science (NIPS) have revealed that mutual eye contact synchronizes spontaneous activity in specific areas of the brains of two interacting parties. The finding indicates that this synchronized brain activity is crucial in establishing and facilitating face-to-face social interaction.
PORTLAND, Ore. - In expanding our knowledge of how the brain controls the process of sexual development, researchers at Oregon Healthy & Science University and the University of Pittsburgh have identified for the first time members of an elaborate superfamily of genes that regulate the timing of puberty in highly evolved nonhuman primates. The Zinc finger, or ZNF, gene family comprises approximately 800 individual genes.
A new longitudinal study that examined an intervention for children at high risk of developing behavior problems has found that teaching so-called soft skills was key to preventing criminal and delinquent problems later in life. Soft skills, such as self-control and social skills, are personality traits, attitudes, and motivations not included in traditional measures of intelligence.
The study was conducted at Duke University and appears in the journal Child Development.
Children with attention deficit hyperactivity disorder (ADHD) are restless, inattentive, and impulsive, and they have difficulty with social functioning, often having fewer friends and being rejected more than children without ADHD. In a new longitudinal study from Norway, researchers investigated the bidirectional relationship between the development of ADHD symptoms in young children and rejection by peers.
The ability of baby fish to find a home, or other safe haven, to grow into adulthood will be severely impacted under predicted ocean acidification, University of Adelaide research has found.
Published today in the journal Proceedings of the Royal Society B, the researchers report the interpretation of normal ocean sound cues which help baby fish find an appropriate home is completely confused under the levels of CO2 predicted to be found in oceans by the end of the century.
Psychologists at the University of York and University of St Andrews have uncovered the first evidence of tool use by greater vasa parrots (Coracopsis vasa).
Studying ten captive parrots, researchers in the Department of Psychology at York observed the birds adopt a novel tool-using technique to acquire calcium from seashells and also the active sharing of tools among themselves.
MADISON, Wis. -- A study of rats released today shows that blocking a type of RNA produced by what used to be called "junk DNA" can prevent a significant portion of the neural destruction that follows a stroke. The research points toward a future treatment for post-stroke damage, which is often more extensive than the initial destruction that results when blood to the brain is temporarily shut off.
MADISON, Wis. -- Su-Chun Zhang, a pioneer in developing neurons from stem cells at the University of Wisconsin-Madison, has created a specialized nerve cell that makes serotonin, a signaling chemical with a broad role in the brain.
Serotonin affects emotions, sleep, anxiety, depression, appetite, pulse and breathing. It also plays a role in serious psychiatric conditions like schizophrenia, bipolar disorder and depression.
The holidays can be difficult for children with autism spectrum disorder (ASD), particularly because of new or different social situations. One reason scientists believe ASD causes impairment in social interactions is due to an inability to effectively infer other's thoughts and feelings through "theory of mind," or ToM -- the ability to understand the mental states of others and oneself.
Much like trying to watch a video with the audio out of synch, older adults may have difficulty combining the stimuli they see and hear, and it could have implications for rapid decision-making tasks such as driving, according to new research.
Humans learn to very quickly identify complex objects and variations of them. We generally recognize an "A" no matter what the font, texture or background, for example, or the face of a coworker even if she puts on a hat or changes her hairstyle. We also can identify an object when just a portion is visible, such as the corner of a bed or the hinge of a door. But how? Are there simple techniques that humans use across diverse tasks? And can such techniques be computationally replicated to improve computer vision, machine learning or robotic performance?
Researchers at the University of Toronto have found another clue in understanding the cause of what drives Multiple Sclerosis (MS) disease. Their findings were published today in Immunity.
Montreal, December 15, 2015 -- A feather is dropped on the moon from a height of 1.40 metres. The acceleration of gravity on the moon is 1.67 m/s2. Determine the time for the feather to fall to the surface of the moon.
If this physics problem makes you break out in a cold sweat, you are not alone. And yet thousands of students enrol yearly in university classes to undertake the daunting task of solving questions far more complex than that.
Many of them have difficulty overcoming their physics-induced anxiety.
NEW YORK, NY (December 14, 2015)--Researchers have discovered how immune cells triggered by recurrent Strep A infections enter the brain, causing inflammation that may lead to autoimmune neuropsychiatric disorders in children. The study, performed in mice, found that immune cells reach the brain by traveling along odor-sensing neurons that emerge from the nasal cavity, not by breaching the blood-brain barrier directly. The findings could lead to improved methods for diagnosing, monitoring, and treating these disorders.
