It is official, the chytrid Fungi have reached all three of the extant amphibian orders.Chytrid fungi are the cause of global decimation in frogs and toads, as well as newts and salamanders. But, until now, the lesser known caecilians had managed to evade their mycelial grasp. That ends now!Goodbye Mr. Bond CaecilianA recent study released in the journal EcoHealth has found the first cases of chytridiomycosis in the legless amphibians.

(source)Hi Julie, WOW!Dogs in clothes. Corgis in bikinis at the beach. Greyhounds in onesies. We people do some weird things to our canine friends, no?! I'm pretty sure I wouldn't enjoy being dressed up in a padded outfit all day long, so I think I'll pass on sharing that experience with my dogs. As you said, cultural perceptions, ethics and expectations add a whole layer of extra consideration. It's not always easy to work out what dogs want or need. That's why I like........ Read more »

The benefits of taking fish oil and the harm caused by eating red meat, these two nutritional nuggets of wisdom have been passed around so much over the past few decades, we rarely stop to ask if they really do what people claim they do.

Homophobic protestors of gay rights assert things like "homosexuality will lead to the breakdown of civilization," and other such notions. But research is finding that some of these avid protestors are homosexuals themselves. Why is that?

Researchers have mapped the moods of Twitter users from the UK and found that they follow a daily pattern of anger, fear, joy and sadness.
The research paper, posted online last week, was based on approximately 120 million tweets collected during the summer and winter of 2011.
The researchers counted the number of times a tweet expressed anger, fear, joy or sadness and normalised this by the total number of tweets in that hour. This corrected for the inevitably higher use of Twitter during........ Read more »

It’s a familiar story: women who say they are looking to date a kind, sensitive and emotionally expressive guy often end up dating a macho man or a jerk.

Our close evolutionary cousin, the common chimpanzee, comes in four subspecies, each one named after its location along an East-West band in Africa. Yet, there are chimps outside of Africa as well. Many European zoos possess a group of chimpanzees, which often plays a part in conservation plans. After all, the populations of our primate brothers are in steep decline. Habitat destruction, bushmeat hunting, pet trade and disease all take their to... Read more »

Putting the woof in tweet! (source)Hi Julie,Wow! Thanks for sharing the amazing fun tweet-week we had posting for @realscientists on Twitter.

Semrau is a psychologist accused of committing fraud to Medicare and Medicaid. The case became mostly famous, because he asked that fMRI lie detection would be a evidence in court. The judge had to decide if fMRI was admissible and after hearing scientists advocating for both sides, he has decided not to admit such evidence. However, the question is: Will it be possible to use fMRI lie detection one day?, because the reason for not admitting it has been based on the error rates and acceptance by........ Read more »

An unemployed neighbor wins the lottery, a friend who regularly boasts about his good health becomes ill. We are highly sensitive to changing fortunes of others. We want to know who’s doing worse and who’s doing better than before, as these shifts in our social environment may have implications for our own well-being. In particular we are drawn to unexpected changes: underdogs that beat the odds and top dogs that fall from grace. Whether we witness the creation of a hero or the demis........ Read more »

Procrastination is a common behavior in 95 percent of people ( Ellis & Knaus, 1977) and in 15 to 20 percent of that group it can be considered chronic and problematic (Harriot & Ferrari, 1996). Recent research shows that men are more likely to procrastinate than women, that procrastinators tend to be less educated, and that their marriages are more likely to fall apart.
Considering procrastination has little benefit, why is it such a common way of behaving? One of the possible causes is perfo........ Read more »

Nearly every organism that’s ever lived and died (certainly every person you’ve ever met) owes their continued existence to the steady flow of charged, particulate energy that originates from the thermonuclear fusion of our star. It is the most perfectly spherical object ever observed in nature. The Earth, by comparison is lumpy and bulging, not a sphere, but an oblate spheroid (flat at its poles, bulbous around its equatorial regions). Once thought of as average and relatively banal........
