Some loss of memory is often considered an inevitable part of aging, but new research reveals how some people appear to escape that fate. A study by Massachusetts General Hospital (MGH) investigators examines a remarkable group of older adults whose memory performance is equivalent to that of younger individuals and finds that certain key areas of their brains resemble those of young people.

TEMPORARY EPISODES OF DIZZINESS OR LIGHT-HEADEDNESS WHEN STANDING COULD REDUCE BLOOD FLOW TO THE BRAIN WITH LASTING IMPACTS

Malaria mosquitoes prefer to feed – and feed more – on blood from people infected with malaria. Researchers from Stockholm University, the Swedish University of Agricultural Sciences and KTH Royal Institute of Technology have discovered why. The findings can lead to new ways to fight malaria without using poisonous chemicals. The results will be published in the next issue of the journal Science.

Study Suggests Restoring Body’s Blood Factory to Boost Immunity, Fend off Cancers

Common impotence drugs such as Viagra may have a life-prolonging effect on patients who have suffered a myocardial infarction, a paper published by researchers at Karolinska Institutet suggests. The finding, which is published in the scientific journal Heart, calls for the need of prospective studies of impotence drugs in heart attack patients others than only those who suffer from impotence – including women.

Scientists have discovered that resveratrol, a compound in the skin of red grapes and red wine, and metformin, a drug often prescribed to fight type 2 diabetes, have many of the neuroprotective benefits of a low-calorie diet and exercise.

Researchers at Eindhoven University of Technology (TU/e) present a new method that should enable controlled drug delivery into the bloodstream using DNA computers. In the journal Nature Communications the team, led by biomedical engineer Maarten Merkx, describes how it has developed the first DNA computer capable of detecting several antibodies in the blood and performing subsequent calculations based on this input. This is an important step towards the development of smart, ‘intelligent’ drugs that may allow better control of the medication for rheumatism and Crohn’s disease, for example, with fewer side-effects and at lower cost.

The International Potato Center (CIP) launched a series of experiments to discover if potatoes can grow under Mars atmospheric conditions and thereby prove they are also able to grow in extreme climates on Earth. This Phase Two effort of CIP’s proof of concept experiment to grow potatoes in simulated Martian conditions began on February 14, 2016 when a tuber was planted in a specially constructed CubeSat contained environment built by engineers from University of Engineering and Technology (UTEC) in Lima based upon designs and advice provided by the National Aeronautics and Space Administration in Ames Research Center (NASA ARC), California. Preliminary results are positive.
