We summarize the week's scientific breakthroughs every Thursday.
- Paleontology
Some trilobites sported dual digestive tracts
CT scans reveal trilobites with two-lane digestive tracts.
- Neuroscience
Study of psychiatric disorders is difficult in man and mouse
Studying human psychiatric disorders in animals presents a challenge. A new study highlights one of the ways scientists can study human mutations by slipping them into mice.

Close look at new fungus reveals origins, spread of salamander killer
A second chytrid fungus described last year targets salamanders and may be spreading in the animal export trade.

Ten real-life Halloween horrors in the natural world
Vampires and witches are nothing compared to mind-controlling parasites, nose ticks and antibiotic-resistant superbugs.
- Neuroscience
Scratching releases serotonin, making you itch more
Scratching an itch releases serotonin in the brain, which can eventually make the itch sensation worse, a new study shows.
- Earth
Early animals couldn’t catch a breath
Low levels of oxygen may have hindered evolution of animal life hundreds of millions of years ago.
- Animals
Birds large and small hop over obstacles in similar ways
Bipedal birds, from tiny quail to huge ostriches, tackled a step in a similar way, minimizing energy cost and maximizing safety.

New frog species discovered in New York City
A new frog species lives up and down the East Coast. It was discovered when ecologists realized its ‘ribbit’ was distinct from the calls of a lookalike species.

A little good news for giant tortoises in the Galapagos
The giant tortoise population on the Galapagos island of Española is on the rebound, but there are still concerns about other markers of conserving the endangered species.
- Microbes
Frozen caribou feces offers look at virus evolution
Genetic material extracted from caribou poop gives hints about how viruses evolve.
- Neuroscience
Brain difference found in people with chronic fatigue
Abnormality found in the brains of a small number of people with chronic fatigue syndrome is intriguing, but needs to be confirmed with more patients.
- Paleontology
Ancient jellyfish suffered strange, sandy death
A fossil hints at the unusual series of events that led to an ancient jellyfish’s preservation and may offer clues to understanding odd sand deposits found elsewhere.
