Eating your greens could enhance sport performance

 

Nitrate supplementation in conjunction with Sprint Interval Training in low oxygen conditions could enhance sport performance a study has found according to Science daily.

Researchers carried out a study with twenty-seven moderately trained participants. These were given nitrate supplements ahead of Sprint Interval Training (SIT), which took the form of short but intense cycling sessions three times a week.

Nitrate is commonly found in diets rich in leafy green foods, like spinach and is important for the functioning of the human body, especially during exercising.

To assess differences in performance in different conditions, the study included workouts in normal oxygen conditions and in hypoxia conditions, which are low oxygen levels such as those found in high altitudes.

Driving or talking? The brain concentrates on one thing at a time

When we are busy with something that requires the use of sight, the brain reduces hearing to make it easy for us. This is the conclusion of a study conducted by researchers. The results give researchers a deeper understanding of what happens in the brain when we concentrate on something.

"The brain is really clever, and helps us to concentrate on what we need to do. At the same time, it screens out distractions that are extraneous to the task. But the brain can't cope with too many tasks: only one sense at a time can perform at its peak. This is why it's not a good idea to talk on the phone while driving," says Jerker Rönnberg, professor of psychology with a focus on disability research.

He and his colleagues have investigated what happens in our brains when we are occupied by a visual task. One example is a student is taking an exam, while another is a person driving a car. The researchers also wanted to see how concentration changes when the background noise increases.

Malaria stopped with single dose of new compound

Scientists say they have found a new compound that stops malaria in animal studies with a single, low dose.

Tests in mice showed the one-off treatment prevented infection for the full 30 days of the study.

The chemical compound fought early infection in the liver, as well as malaria parasites that were circulating in the blood, according to BBC.

Brain radiotherapy 'no benefit' for lung cancer spread

Whole brain radiotherapy is of no benefit to people with lung cancer which has spread to the brain, says research.

A trial of more than 500 patients found that it did not prolong or improve their quality of life any more than other forms of treatment, according to BBC.

Laser pointers can cause irreversible vision loss for kids

Used incorrectly, laser pointers can damage the retina of the eye and may cause some irreversible vision loss, according to researchers who treated four boys for these injuries.

Doctors, teachers and parents should be aware that this can happen, and limit children’s use of laser pointers, the authors write, according to Reuters.

“This was initially thought of as a never event, that never happened,” said senior author Dr. David R. P. Almeida of Vitreo Retinal Surgery, PA, in Minneapolis, Minnesota. “But we have four cases so it does happen sometimes,” though it’s still unusual.
