Putting raw spinach in a smoothie is the healthiest way to eat the vegetable because heat destroys its antioxidants, scientists discover

Chopping up spinach and putting it in a smoothie is the healthiest way to eat it, research suggests.

Cooking the leafy vegetable breaks down its antioxidants, while mixing it raw with yoghurt or milk helps to release the powerful nutrient lutein, according to Daily Mail.

Boiling or frying spinach are sure-fire ways of destroying lutein, a study found.

Lutein helps lower the risk of heart attacks and prevents eye damage, previous research suggests.

People with schizophrenia experience emotion differently from others, 'body maps' show

Colorful figures of the human body are helping Vanderbilt University researchers understand how people experience emotion through their bodies and how this process is radically altered in people with schizophrenia, according to Science Daily.

Sohee Park, Gertrude Conaway Vanderbilt Professor of Psychology, and Ph.D. student Lénie J. Torregrossa compared individuals with schizophrenia with matched control participants, asking each to fill in a "body map" in a way that correlates to the way they physically experience emotion. They used a computerized coloring task to locate where participants feel sensations when they experience, for example, anger or depression.

The outcomes differed radically between groups, with the control group showing distinct maps of sensations for 13 different emotions, indicating specific patterns of increased arousal and decreased energy across the body for each emotion. However, in individuals with schizophrenia, there was an overall reduction of bodily sensation across all emotions.

E-bandage generates electricity, speeds wound healing in rats

Skin has a remarkable ability to heal itself. But in some cases, wounds heal very slowly or not at all, putting a person at risk for chronic pain, infection and scarring. Now, researchers have developed a self-powered bandage that generates an electric field over an injury, dramatically reducing the healing time for skin wounds in rats, according to Science Daily.

Chronic skin wounds include diabetic foot ulcers, venous ulcers and non-healing surgical wounds. Doctors have tried various approaches to help chronic wounds heal, including bandaging, dressing, exposure to oxygen and growth-factor therapy, but they often show limited effectiveness. As early as the 1960s, researchers observed that electrical stimulation could help skin wounds heal. However, the equipment for generating the electric field is often large and may require patient hospitalization. Weibo Cai, Xudong Wang and colleagues wanted to develop a flexible, self-powered bandage that could convert skin movements into a therapeutic electric field.

Swimming, walking or lifting weights in the gym 'treats high blood pressure as well as drugs'

Exercise is as effective as prescription drugs at lowering blood pressure, researchers have found.

Regularly walking or swimming and doing simple weight training treats high blood pressure as well as taking pills such as beta blockers or ACE inhibitors, according to data from 40,000 people.

Some 62,000 people killed every year from stroke and heart attacks due to poor blood pressure control alone - so doctors are desperate to extent effective treatment to more people, according to Daily Mail .

Passive exposure alone can enhance the learning of foreign speech sounds

Ability to understand and subsequently speak a new language requires the ability to accurately discriminate speech sounds of a given language. When we start to learn a new language the differences between speech sounds can be very difficult to perceive. With enough active practice the ability to discriminate the speech sounds enhances.

This type of learning is called perceptual learning. As a consequence of learning, new memory traces are formed in the brain. In contrast, in early infancy passive sound exposure is enough to enhance auditory discrimination during so called sensitive period, according to Science Daily.
