Why do oysters choose to live where they could be eaten?
05-01-2007 · EurekAlert!According to an article in the May edition of Ecological Monographs, a team of scientists has found that despite the risk of being eaten by cannibalistic adults, oyster larvae choose to settle in areas of high oyster concentrations to take advantage of future benefits of increased reproductive capacity when they mature. In the case of oyster larvae, that selection can be a life or death decision.

- Rising Ocean Temperatures, Pollution Have Oysters In Hot Water
10-13-2006 · ScienceDaily
Oysters exposed to high water temperatures and a common heavy metal are unable to obtain sufficient oxygen and convert it to cellular energy, according to a new study presented at the American Physiological Society conference, "Comparative Physiology 2006." The study showed how cadmium reduces the oyster's tolerance of warmer water temperatures and makes it more vulnerable during the summer when water temperatures rise.

- Study finds oysters can take heat and heavy metals, but not both
12-13-2006 · EurekAlert!
Could low-level heavy metal pollution be combining with warm water temperatures to fatally weaken sea life? A study examining the joint effects of cadmium and temperature on mitochondrial metabolism in oysters finds a combined effect that is potentially lethal and could be a significant contributor to recent oyster declines. The research has broad implications for cold-blooded marine organisms.

- Female pronghorns choose mate based on substance as well as show
10-23-2006 · EurekAlert!
When a female animal compares males to choose a mate, she can't order a laboratory genetic screen for each suitor. Instead, she has to rely on external cues that may indicate genetic quality. Until now, biologists have focused on elaborate ornaments, such as the peacock's tail, as cues that females might use.

Single parents concerned about the developmental health of their children may want to choose new partners slowly and deliberately. New research shows that the more transitions children go through in their living situation, the more likely they are to behave badly.

- Leaderless movement proves illusive
09-13-2007 · EurekAlert!
A new study by University of Alberta researcher Paul Joosse cautions against any surety about the ideological motivations behind the Earth Liberation Front. The Earth Liberation Front uses an organizational strategy called "leaderless resistance," whereby small cells choose when, how, and against whom to act -- and then make a claim of responsibility on behalf of the mother group.

- Worried about prostate cancer? Tomato-broccoli combo shown to be effective

A new University of Illinois study shows that tomatoes and broccoli -- two vegetables known for their cancer-fighting qualities -- are better at shrinking prostate tumors when both are part of the daily diet than when they're eaten alone.

- Learning to live with oxygen on early Earth
10-16-2006 · EurekAlert!
Scientists at the Carnegie Institution and Penn State University have discovered evidence showing that microbes adapted to living with oxygen 2.72 billion years ago, at least 300 million years before the rise of oxygen in the atmosphere. The finding is the first concrete validation of a long-held hypothesis that oxygen was being produced and consumed by that time and that the transition to an oxygenated atmosphere was long term.

- Additional hormone therapy use after radiation for some prostate cancers extends survival
11-06-2006 · EurekAlert!
The largest study examining the benefits of long-term use of hormone therapy after radiation treatment for prostate cancer shows men with aggressive locally advanced disease live longer if hormones are used for an additional 24 months. Research also showed other significant benefits for those with less aggressive cancers who receive hormones.

- Immigrants of a feather don't necessarily flock together
12-06-2006 · EurekAlert!
The traditional idea that immigrants cluster together in neighborhoods with their countrymen after coming to the United States and move away after achieving economic success is far from universal. New research indicates that who immigrants marry or partner with has a strong influence on where they live.
