To quantify the impact of genetic improvement in wheat, disease and climate change over a 26-year period, researchers examined wheat variety yield data from Kansas performance tests, along with location-specific weather and disease data. | Read More » Discovery shows cerebellum plays important role in sensing limb position and movement  | New findings show, for the first time, the link between the brain's cerebellum and proprioception, or the body's ability to sense movement and joint and limb position. A new study uncovers a previously unknown perceptual deficit among cerebellar patients, suggesting that damage to this portion of the brain can directly impact a person's ability to sense the position of their limbs and predict movement. This discovery could prompt future researchers to reexamine physical therapy tactics for cerebellar patients, who often have impaired coordination or appear clumsy. | Read More » Gravity variations over Earth much bigger than previously thought  | Scientists have created the highest-resolution maps of Earth's gravity field to date -- showing gravitational variations up to 40 percent larger than previously assumed.

On the one hand, the American Psychiatric Association has introduced the fifth iteration of the psychiatric diagnostic manual, DSM-V, representing the current best effort of the brightest clinical minds in psychiatry to categorize the enormously complex pattern of human emotional, cognitive, and behavioral problems. On the other hand, in new and profound ways, neuroscience and genetics research in psychiatry are yielding insights that challenge the traditional diagnostic schema that have long been at the core of the field. | Read More » Children with behavioral problems more at risk of inflammation, health problems later in life  | Children with behavioral problems may be at risk of many chronic diseases in adulthood including heart disease, obesity, diabetes, as well as inflammatory illnesses (conditions which are caused by cell damage). Researchers found that children with behavioral problems at the age of 8, had higher levels of two proteins (C-reactive protein -- CRP; and Interleukin 6 -- IL-6) in their blood when tested at the age of 10. Having raised levels of CRP and IL-6 can be an early warning sign that a person may be at risk of chronic or inflammatory conditions later in life. | Read More » Robotic therapy aids kids' handwriting skills  | Researchers are working to develop an exciting new robotic device that helps children to practice and improve their hand coordination. | Read More » Religious leaders can be key to biological diversity  | Leaders of the major world religions can play a key role in preserving biological diversity.

Unfortunately they have been in great decline in recent years, much of it due to the effects of global climate change. One such effect, called bleaching, occurs when the symbiotic algae that are essential for providing nutrients to the coral either lose their identifying photosynthetic pigmentation and their ability to perform photosynthesis or disappear entirely from the coral's tissue. Without a healthy population of these algae, the coral cannot survive. | Read More » Scientists confirm existence of largest single volcano on earth  | Scientists have uncovered the largest single volcano yet documented on Earth.
