Recently  we started this feature of interviews with leading scientists and thinkers on the subject of energy. The first interview was with Dennis M.

Research has uncovered alarming evidence that high Arctic ponds, many which have been permanent bodies of water for thousands of years, are completely drying out during the polar summer. These shallow ponds, which dot the Arctic landscape, are important indicators of environment change and are especially susceptible to the effects of climate change because of their low water volume.

Marianne Douglas, Professor of Earth and Atmospheric Science and Director of the Canadian Circumpolar Institute at the University of Alberta, and John Smol, Professor of Biology at Queen’s University, studied these unique Arctic ponds for the past 24 years, collecting detailed data such as water quality and water levels from approximately 40 ponds.

On school days, teen boys who play video games appear to spend less time reading and teen girls who play video games appear to spend less time doing homework than those who do not play video games, according to a report in the July issue of Archives of Pediatrics & Adolescent Medicine. Overall, video game players did not spend less time than non-video game players interacting with parents and friends.

“The rapid growth of video game popularity has generated concern among practitioners, parents, scholars and politicians,” according to background information in the article.

The first baby to be created from an egg that had been matured in the laboratory, frozen, thawed and then fertilised, has been born in Canada. Three other women are pregnant by the same process. The research was presented to the 23rd annual meeting of the European Society of Human Reproduction and Embryology.

The baby girl was born to one of 20 patients with polycystic ovarian syndrome (PCOS) or with ovaries that had been detected to be polycystic by ultrasound (U/S), who took part in the trial at McGill Reproductive Center, Montreal, Canada. The baby is progressing well.

A team of biomedical engineers at Virginia Tech and the University of California at Berkeley has developed a new minimally invasive method of treating cancer, and they anticipate clinical trials on individuals with prostate cancer will begin soon.

The process, called Irreversible Electroporation (IRE), was invented by two engineers, Rafael V. Davalos, a faculty member of the Virginia Tech–Wake Forest University School of Biomedical Engineering and Science (SBES), and Boris Rubinsky, a bioengineering professor at the University of California, Berkeley.

Electroporation is a phenomenon known for decades that increases the permeability of a cell from none to a reversible opening to an irreversible opening. With the latter, the cell will die.

Older adults who have difficulty identifying common odors may have a greater risk of developing problems with thinking, learning and memory, according to a report in the July issue of Archives of General Psychiatry.

Mild cognitive impairment—or a decline in thinking, learning and memory abilities—is increasingly recognized as a precursor to Alzheimer’s disease, according to background information in the article. Impairments in the ability to recognize odors have been associated with more rapid cognitive decline and also with the development transition from mild cognitive impairment to Alzheimer’s disease. However, little is known about factors that predict the development of mild cognitive impairment.

Researchers at the University of Utah and elsewhere have developed a new way to predict when vegetation dries to the point it is most vulnerable to large-scale fires in the Santa Monica Mountains near Los Angeles. And this year’s forecast says the highest-risk fire period will begin July 13 – weeks earlier than usual.

Despite that, the new study also shows that unlike other areas of the western United States, global warming has not caused any apparent long-term trend toward early fire seasons in the Santa Monicas.

The scientists eventually hope to expand their unique fire-risk forecasting method to all of Southern California and beyond.

We’ve all wondered how a seemingly healthy person can actually be at high risk for heart disease or a heart attack. Now researchers have uncovered a new clue to this mystery. The culprit: myeloperoxidase (MPO), a protein secreted by white blood cells that both signals inflammation and releases a bleach-like substance that damages the cardiovascular system.

Although MPO is intended to kill harmful bacteria, it may instead inflame the body’s arteries and cripple protective substances in the blood, according to a study published in the Journal of the American College of Cardiology (JACC). As a result, long before conventional risk factors set off alarms, elevated MPO levels signal that harmful plaque has been building up.

Psychologists from the University of Exeter have identified an 'early warning signal' in the brain that helps us avoid repeating previous mistakes. Published in the Journal of Cognitive Neuroscience, their research identifies, for the first time, a mechanism in the brain that reacts in just 0.1 seconds to things that have resulted in us making errors in the past.

Previous research has shown that we learn more about things for which we initially make incorrect predictions than for things for which our initial predictions are correct. The element of surprise in discovering we are wrong is conducive to learning, but this research is the first to show how amazingly rapid our brain’s response can be.
