When you hear people talk about diversity, they often mean they want a majority of people just like them. Anything less is worrisome. It's that way in sports teams, the halls of academia and even church.

People who are part of a religious congregation's largest racial group are more likely to feel they belong and be more involved, whether their group is barely half or nearly all of the members, according to surveys collated in a sociology paper.

A standard joke among the elites of New York City And Los Angeles is that everyone is in therapy - it's possible because they are likely more rich and, it turns out, many psychiatrists are not interested in patients who aren't wealthy enough to not need to use insurance to pay.

But Congress, motivated by public outrage at recent mass shootings and their link to psychiatric medications, want mental health care to be covered by insurance and for psychiatrists to have the same standards as government-paid doctors have.

A new solar panel design and ceramic material points the way to potentially providing sustainable power that can be price competitive and efficient. It also reaches a four-decade-old goal of discovering a bulk photovoltaic material that can harness energy from visible and infrared light, not just ultraviolet light.

The stereotype is that athletes are often less smart than their non-athletic peers and a new paper says it may not be that athletes go into more physical pursuits but that the sports themselves may lead to lower test scores.

Two groups of Dartmouth athletes were studied: 80 football and ice hockey players in the contact sports group, and 79 athletes drawn from such non-contact sports as track, crew and Nordic skiing. The football and hockey players wore helmets equipped with accelerometers, which enabled the researchers to compile the number and severity of impacts to their heads. Players who sustained a concussion during the season were not included in the analysis.

A hydrogel scaffold for craniofacial bone tissue regeneration starts as a liquid and then solidifies into a gel in the body and liquefies again for removal. 

The material is a soluble liquid at room temperature that can be injected to the point of need. At body temperature, the material turns instantly into a gel to help direct the formation of new bone to replace that damaged by injury or disease. It conforms to irregular three-dimensional spaces and provides a platform for functional and aesthetic tissue regeneration and is intended as an alternative to prefabricated implantable scaffolds. It then liquefies again for removal. 

Scholars at Indiana University  say that lower citation rates for women are due to bias.

In the past, fewer women worked outside the home and as that gradually shifted, there was hiring bias, which means historically women have had fewer science citations than men. That's simple numbers, just like fewer handicapped people and conservatives get citations in modern academia. But is that bias?

The authors say it is, and speculate it might be the trickle-down effects of having fewer female deans in science.
