Bad news for bivalves comes this week from scientists studying ocean acidification.
Ocean water in parts of the world is changing. Its chemistry is very slowly becoming more acidic, like lemon juice, and less alkaline, a la baking soda.
The change so far is small â you wouldn't notice if you swam in the ocean or even drank it (not recommended, in any case). But numerous scientific studies show that it could get worse. One reason is that as humans produce more carbon dioxide, a lot is absorbed into the oceans. That makes the water more acidic.
Babies at high risk for becoming allergic to peanuts are much less likely to develop the allergy if they are regularly fed foods containing the legumes starting in their first year of life.
That's according to a big new study released Monday involving hundreds of British babies. The researchers found that those who consumed the equivalent of about 4 heaping teaspoons of peanut butter each week, starting when they were between 4 and 11 months old, were about 80 percent less likely to develop a peanut allergy by their fifth birthday.

The hunt for coyotes starts in Dan Eaton's truck.
Eaton is a professional trapper. He's been doing it for a long time â since he was 10 years old â so he's nonchalant about the dead beaver in the truck bed that he sometimes uses to attract coyotes.
On a recent day, Eaton heads to a trap line set on private hunting land outside Augusta, Ga.
"Everybody wants you to trap coyotes for free until you tell them you're collaring them and letting them go," Eaton says.
Could using a dishwashing machine increase the chances your child will develop allergies? That's what some provocative new research suggests â but don't tear out your machine just yet.
The study involved 1,029 Swedish children (ages 7 or 8) and found that those whose parents said they mostly wash the family's dishes by hand were significantly less likely to develop eczema, and somewhat less likely to develop allergic asthma and hay fever.

The sense of smell is a powerful trigger â capable of calling to mind the sight of a new car, or the memory of a freshly mown lawn from many years past. But this power doesn't just serve to remind; it's also captivating scientists and inspiring a burgeoning subculture in Los Angeles, where many people are collecting fragrances like some people collect stamps.
The Voyager spacecraft have revolutionized our understanding of our solar system since their launch in 1977. After decades of sending back data on our planetary neighbors, Voyager 1 and 2 are entering new territory: interstellar space.
In a new book, The Interstellar Age: Inside The Forty-Year Voyager Mission, planetary scientist Jim Bell shares the amazing human stories behind the machines' mission.
For more than 500 million years, sea creatures have been getting bigger â much bigger as it turns out, according to a study by scientists who say that the evolutionary trend toward larger body size fits with a 19th-century principle known as Cope's rule.
The rule, first posited in the late 1800s by Edward Drinker Cope, "states that evolution tends to increase body size over geologic time in a lineage of populations."
Speed. That's key to ending the Ebola epidemic, health officials have been saying for months. Now there's a new tool to help do the trick.
The World Health Organization approved the first quick test for Ebola Friday. The test gives results in about 15 minutes, instead of hours. So people infected can get treatment and be quarantined more quickly.
"It's definitely a breakthrough," WHO spokesman Tarik Jasarevic said Friday in Geneva.
