The fungal disease known as white-nose syndrome has spread to bat colonies throughout eastern North America over the past few years, causing bat populations to crash and leading to various claims about what to blame for it.

But there is no magic bullet, finds a new study, because it is related to seasonal dynamics of infection and transmission too.

Popular meniscal tear surgery may increase the risk of osteoarthritis and cartilage loss, according to a presentation at the annual meeting of the Radiological Society of North America.

The new study focused on the meniscus, a wedge-shaped piece of cartilage in the knee that acts as a shock absorber between the femur, or thighbone, and tibia, or shinbone. The two menisci in each knee also play an important role in joint stability. Meniscal tears are among the most common knee injuries, and surgery is often performed to alleviate pain.

In a bygone era, the macho stereotype of the maverick doctor bucking convention, or the Marine running toward danger rather than away from it, inspired young men to want to be bold.

No longer. Modern youth have become so convinced that being bold is a negative that they perceive occupations like that as a 'macho' stereotype and are driven away because they do not feel competent.  Although numerous papers have noted the negative impact of gendered workplace stereotypes on women, far less attention has been paid to their effect on men.   

Ten years after carbon emissions happen, the warming effect is maximized. Methane is even quicker, and far more potent, though it also disappears much more rapidly.

It's always a good idea to reduce cost and radiation and when it comes to kids and chest X-rays, that cost reduction should be happening a lot more.

If you ask a female doctor why she didn't go into physics, she is not going to tell you it's because there are more men in physics and that is intimidating. Instead, she will say it's because she wanted to help people or she liked medicine.

Yet a number of sociological claims insist she doesn't really know why she chose not to go into physics, and it may instead be because of subtle self-bias or stereotype threat.
