Melt water on Mars could sustain life, new research suggests - 0 views

  • Areas of the planet's northern and southern hemispheres have alternately thawed and frozen in recent geologic history
    • Brandon Moseley
       
      One of the biggest reasons living on Mars seems so impossible is the inexistence of water. With this new discovery, it could not just be possible, but probable, that solving the other issue of breathing could mean we could live on Mars.

Should you listen to music while studying? - University of Phoenix - 1 views

  • Try listening to music without lyrics. Lyrics can be distracting, whereas instrumental music heightens concentration.
  • Try to avoid music that is new. You may find yourself paying closer attention to music that is not familiar.
  • Try to continue one style of studying, such as memorization or math, when listening to a particular type of music.
  •  
    "The scientists drew a link between memory recall to musical tempo. A tempo of 60 beats per minute activates the right hemisphere of the brain, while the material being studied activates the left hemisphere of the brain. With both hemispheres activated, the brain can process information more efficiently."

    "Scientists conducted a series of studies in the 1990s examining the influence of music on memory recall. The research supported the positive effects of background music when studying. The research also suggested that music, especially classical music, heightened arousal and mood, as it reduced blood pressure, heartbeat and stress."

She was being coaxed to wear the eye-tracking headgear, which consists of two cameras - one that's looking out on the scene to get the baby's perspective, and another that's looking at the eye to track the movement of the pupil. A computer analyzed both camera views to determine exactly where Finn was looking.

      Summary- Research in Nicaragua's Bosawas Biosphere Reserve showed that male dogs seem to enjoy better success rates than younger and female dogs do. Variables such as age and sex play a big role in finding your good hunting dog. The older the better, as well as the bigger the better. Males tend to always be bigger than female dogs and with having a big dog it's able to track larger prey therefore returning more game and making out for a better hunter.

      Who would of thought that there would be a concern of human and animals sharing flu's.
  • The first recorded, probable case of fatal human-to-cat transmission of the pandemic H1N1 flu virus occurred in Oregon in 2009, Loehr said. Details were published in Veterinary Pathology, a professional journal. In that instance, a pet owner became severely ill with the flu and had to be hospitalized. While she was still in the hospital, her cat - an indoor cat with no exposure to other sick people, homes or wildlife - also died of pneumonia caused by an H1N1 infection.

  • Veterinarians who encounter possible cases of this phenomenon can obtain more information from Loehr or Jessie Trujillo at Iowa State University. They are doing ongoing research to predict, prevent or curtail emergent events.

  • To examine why infants need to dwell on objects to learn about them, the researchers created two different models. One model learned in a "responsive" world: Every time the model looked away from a new object, the object was jiggled to get the model to look at it again. The other model learned in a "nonresponsive" world: when this model looked at a new object, objects elsewhere were jiggled to distract it. The results showed that the responsive models“learned about new objects more robustly, more quickly, and are better learners in the end,

  • babies also look to speakers' faces for important social cues about what they're hearing
  • So he and doctoral student Amy Hansen-Tift tested nearly 180 babies, groups of them at ages 4, 6, 8, 10 and 12 months. How?

      Lewkowicz and Hansen tested how babies learn
  • They found a dramatic shift in attention: When the speaker used English, the 4-month-olds gazed mostly into her eyes. The 6-month-olds spent equal amounts of time looking at the eyes and the mouth. The 8- and 10-month-olds studied mostly the mouth.

      Different age groups studied the speaker differently.
  • At 12 months, attention started shifting back toward the speaker's eyes.

  • Differential diagnosis generally involves ruling out the effects of chemical substances and medical (as opposed to psychological) conditions. When evaluating children, it is also important to ensure that symptoms are distinguishable from imaginary play (American Psychiatric Association, 2000).
  • In clinical populations, the estimated prevalence of DID ranges from 0.5 to 1.0% (Maldonado, Butler, & Spiegel, 2002). In the general population, estimates of prevalence are somewhat higher, ranging from 1-5% (Rubin & Zorumski, 2005).

  • Dissociative Identity Disorder is linked to childhood abuse in 95-98% of the cases
  • Studies on genetic factors contributing to DID present mixed findings. However, one study involving dyzogotic and monozygotic twins found that considerable variance in experiences of pathological dissociation could be attributed to both shared and non-shared environmental experiences, but heritability appeared to have no effect (Waller & Ross, 1997).
  • Treatment most commonly follows a framework of “1) safety, stabilization and symptom reduction, 2) working directly and in depth with traumatic memories, and 3) identity integration and rehabilitation” (p. 89).

  • ...3 more annotations...
  • Compared to the normal control group, the children with ADHD showed abnormal functional activity in several regions of the brain involved in the processing of visual attention information
  • "What this tells us is that children with ADHD are using partially different functional brain pathways to process this information, which may be caused by impaired white matter pathways involved in visual attention information processing," Dr. Li said.
  • According to the National Institute of Mental Health, there is no single test capable of diagnosing a child with the disorder. As a result, difficult children are often incorrectly labeled with ADHD while other children with the disorder remain undiagnosed.

  • After about 20 minutes, 24 of the 26 babies squeezed their eyelids together when the tone was sounded without the puff of air.
  • The brain waves of the 24 infants were found to change, providing a neural measurement of memory updating.

      Infants learn while their awake but can also be found while they are asleep.
  • Learned eyelid movement reflects the normal functioning of the circuitry in the cerebellum, a neural structure at the base of the brain. This study's method potentially offers a unique non-invasive tool for early identification of infants with atypical cerebellar structure, who are potentially at risk for a range of developmental disorders, including autism and dyslexia, she said.
  • Newborn infants' sleep patterns are quite different than those of older children or adults in that they show more active sleep where heart and breathing rates are very changeable," she said. "It may be this sleep state is more amenable to experiencing the world in a way that facilitates learning."
  • Another factor is that infants' brains have greater neural plasticity, which is the ability for the neural connections to be changed
