Scientists have reported the explosive growth of a young star that is thought to be formed within the past 100,000 years in our Milky Way galaxy.
Astrophysical Journal Letters
Astronomers used the large international telescope, the Atacama Large Millimeter Array (ALMA) in northern Chile, and studied the star and its surroundings. They studied a young, newly created star in the Milky Way that has such an explosive growth that it was about 10........ Read more »

Studying, as I do, in a department of family relations, I have become interested in family relationships and parenting. Accordingly, I have begun to take note of interesting studies that link family dynamics and parenting with eating disorders, including studies that look at the sibling relationship (as I wrote about here), family-based treatment, and motherhood/fatherhood in the context of eating disorders.
The literature appears to have shifted, lately, from a focus on “eating-disorder........ Read more »

“One of the fundamental questions of evolutionary biology is how vertebrates with all the same genes display such vastly different characteristics. The Burmese python is a great way to study that because it is so extreme,” Castoe, who began working on the python project as a postdoctoral fellow at the University of Colorado School of Medicine in the laboratory of associate professor and paper corresponding author David D. Pollock.
Castoe said: “We’d like to know how th........ Read more »

Diseases are an interesting thing. The development and location of an area can drastically change the types of diseases present, and which are most deadly. If you look at global health maps, such as HealthMap, you can see how drastically different outbreaks are occurring in different areas.

If turtles had realtors, their motto would also be "Location, location, location!"—but not because they care about a scenic vista. The spot a mother turtle chooses to dig her nest determines whether her young will be males or females. This might even be the most important factor in her decision.A female painted turtle (Chrysemys picta) is not an over-involved parent. She digs a hole in the dirt, lays a batch of eggs there, and buries them. Then she returns to her freshwater life without giving........ Read more »

Some observations come before you realize how important they are. Only later do you slap your forehead and realize that you should have taken more detailed notes, because the likelihood of you seeing such a thing again is slim.
