Mars once had warm water

Evidence of sufficiently warm water on Mars provides proof that the Red Planet could have supported life, a research suggests.

The study by the University of Leicester and The Open University, determined that water temperatures on the Red Planet ranged from 50°C to 150°C. Microbes on Earth can live in similar waters, for example in the volcanic thermal springs at Yellowstone Park, the scientists behind the research pointed out.

The research is based on detailed scrutiny of Mars meteorites on Earth using powerful microscopes in the University of Leicester Department of Physics and Astronomy. This was followed-up by computer modeling work at The Open University.

Dr John Bridges, Reader in Planetary Science in the University of Leicester Space Research Centre and Lead Author, said: “Rovers on Mars – the Mars Exploration rovers Spirit and Opportunity, and the Mars Science Laboratory rover Curiosity – are studying rocks to find out about the geologic history of the Red Planet. Some of the most interesting questions are what we can find out about water, how much there was and what temperature it might have had.”

Meditation more effective in warding off cold than pills

Meditation could be very useful at preventing winter ailments than popping vitamins or herbal remedies as “insurance policy” to stave off colds and flu, a new study has revealed.

According to a study from the University of Wisconsin–Madison, adults who meditated or did moderately intense exercise, such as a brisk walk, for eight weeks suffered fewer colds than those who did nothing, the Daily Mail reported. Previous research has found that mindfulness meditation may improve mood, decrease stress, and boost immune function. The 149 people in this new study were divided into three groups. One performed mindful meditation, a type of meditation that essentially involves focusing the mind on the present.

Another group jogged regularly for eight weeks while the third group did nothing.
The researchers then followed the health of the volunteers through the winter from September to May, although they didn’t check whether or not people carried on exercising or meditating after the eight–week period.

The participants were observed for cold and flu symptoms such as a runny nose, stuffiness, sneezing, and sore throat.

 
Milk-drinking kids reap physical benefits in old age

Children who regularly drink milk are physically fitter in old age, according to new research.

Researchers from Bristol University found that elderly people who a milk started a milk drinking habit as a child were able to walk faster and were much less likely to suffer problems with balance.

About one glass of milk a day in childhood was linked to a 5 percent faster walking time and 25 percent lesser chance of poor balance in older age, the study found.  The team of British researchers used historical diet records from two large studies to assess the childhood habits of more than 1,500 men ages 62-86.

They measured the impact of diet, specifically milk, protein, calcium and fat intake, on current performance and mobility in follow-up.

Elderly participants were put through a series of activities, including walking, get-up-and-go, and balance tests. Childhood calcium, protein and milk intake were all associated with advantages in mobility later in life.

The researchers also found that childhood milk drinkers were also likely to be adult milk drinkers, emphasizing the benefits of establishing lifelong healthy habits.  Among the many health habits to begin at a young age, experts recognize the importance of beginning the day with breakfast.
