Running too far, too fast, and too long speeds progress 'to finish line of life'

Limit vigorous exercise to 30 to 50 minutes a day max, say researchers

2012-11-29
(Press-News.org) Vigorous exercise is good for health, but only if it's limited to a maximum daily dose of between 30 and 50 minutes, say researchers in an editorial published online in Heart.

The idea that more and more high intensity exercise, such as marathons, can only do you good, is a myth say the US cardiologists, and the evidence shows that it's likely to more harm than good to your heart.

"If you really want to do a marathon or full distance triathlon, etc, it may be best to do just one or a few and then proceed to safer and healthier exercise patterns," they warn.

"A routine of moderate physical activity will add life to your years as well as years to your life. In contrast, running too far, too fast, and for too many years may speed one's progress to towards the finishing line of life."

Can a genetic variation in the vitamin D receptor protect against osteoporosis?

Can a genetic variation in the vitamin D receptor protect against osteoporosis?
2012-11-29
New Rochelle, NY, November 29, 2012—Osteoporosis, or reduced bone mineral density that can increase the risk of fractures, may affect as many as 30% of women and 12% of men worldwide. One risk factor for osteoporosis is vitamin D deficiency. A modified form of the vitamin D receptor present in some individuals may lower their risk for developing osteoporosis, according to an article in Genetic Testing and Molecular Biomarkers, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available on the Genetic Testing and Molecular Biomarkers website. To ...

Post-divorce journaling may hinder healing for some

2012-11-29
Following a divorce or separation, many people are encouraged by loved ones or health-care professionals to keep journals about their feelings. But for some, writing in-depth about those feelings immediately after a split may do more harm than good, according to new research. In a study of 90 recently divorced or separated individuals, psychological scientist David Sbarra of the University of Arizona and colleagues found that writing about one's feelings can actually leave some people feeling more emotionally distraught months down the line, particularly those individuals ...

Drug may offer new approach to treating insomnia

2012-11-29
MINNEAPOLIS – A new drug may bring help for people with insomnia, according to a study published in the November 28, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology. The drug, suvorexant, blocks the chemical messengers in the brain called orexins, which regulate wakefulness. Other drugs for insomnia affect different brain receptors. Taking the drug suvorexant increased the amount of time people spent asleep during the night, according to the study. The study involved 254 people ages 18 to 64 who were in good physical and ...

Tiny algae shed light on photosynthesis as a dynamic property

2012-11-29
One of the first chemical reactions children learn is the recipe for photosynthesis, combining carbon dioxide, water and solar energy to produce organic compounds. Many of the world's most important photosynthetic eukaryotes such as plants did not develop the ability to combine these ingredients themselves. Rather, they got their light-harnessing organelles -- chloroplasts -- indirectly by stealing them from other organisms. In some instances, this has resulted in algae with multiple, distinct genomes, the evolutionary equivalent of a "turducken*." Chloroplasts originally ...

Morality-based judgments are quicker, more extreme than practical evaluations

2012-11-29
Judgments made after a moral evaluation are quicker and more extreme than the same judgment based on practical considerations, but morality-based evaluations can be more easily shifted and made with other considerations in mind, according to research published November 28 in the open access journal PLOS ONE by Jay Van Bavel and colleagues from New York University. Previous research has suggested that moral reasoning usually occurs after a person makes a decision, as a post hoc justification of their choice, rather than the basis for the decision itself. This new study ...

More omnivore dilemmas: Seasonal diet changes can cause reproductive stress in primates

More omnivore dilemmas: Seasonal diet changes can cause reproductive stress in primates
2012-11-29
When seasonal changes affect food availability, omnivores like blue monkeys adapt by changing their diets, but such nutritional changes may impact female reproduction, according to research published November 28 in the open access journal PLOS ONE by Steffen Foerster from Barnard College, and colleagues from Columbia University and the Smithsonian Institution. The authors found that levels of fecal glucocorticoids (fGC), a stress marker, increased when female monkeys shifted their diet towards lower quality fallback foods, whereas the levels decreased when the monkeys ...

Skeletons in cave reveal Mediterranean secrets

2012-11-29
Skeletal remains in an island cave in Favignana, Italy, reveal that modern humans first settled in Sicily around the time of the last ice age and despite living on Mediterranean islands, ate little seafood. The research is published November 28 in the open access journal PLOS ONE by Marcello Mannino and colleagues from the Max Planck Institute for Evolutionary Anthropology, Germany. Genetic analysis of the bones discovered in caves on the Egadi islands provides some of the first mitochondrial DNA data available for early humans from the Mediterranean region, a crucial ...

Scientists identify depression and anxiety biomarker in youths

2012-11-29
Scientists have discovered a cognitive biomarker – a biological indicator of a disease – for young adolescents who are at high risk of developing depression and anxiety. Their findings were published today, 28 November, in the journal PLOS ONE. The test for the unique cognitive biomarker, which can be done on a computer, could be used as an inexpensive tool to screen adolescents for common emotional mental illnesses. As the cognitive biomarker may appear prior to the symptoms of depression and anxiety, early intervention (which has proven to be one of the most effective ...

Chemists invent powerful toolkit, accelerating creation of potential new drugs

Chemists invent powerful toolkit, accelerating creation of potential new drugs
2012-11-29
LA JOLLA, CA – Scientists at The Scripps Research Institute (TSRI) have invented a set of chemical tools that is radically simplifying the creation of potential new drug compounds. Pharmaceutical chemists frequently seek to generate dozens or even hundreds of variations of a given compound to see which works best. The new toolkit—described in the November 28, 2012 issue of the journal Nature—makes this process easier and cheaper, enabling previously time- and cost-prohibitive chemical modifications. This fundamental innovation is already being adopted by drug companies ...

New studies show moral judgments quicker, more extreme than practical ones -- but also flexible

2012-11-29
Judgments we make with a moral underpinning are made more quickly and are more extreme than those same judgments based on practical considerations, a new set of studies finds. However, the findings, which appear in the journal PLOS ONE, also show that judgments based on morality can be readily shifted and made with other considerations in mind. "Little work has been done on how attaching morality to a particular judgment or decision may affect that outcome," explains Jay Van Bavel, an assistant professor in New York University's Department of Psychology and one of the ...
