Black women often ignored by social justice movements
Black women are often less likely to be associated with the concept of a 'typical woman' and are viewed as more similar to Black men than to white women, which may lead to some anti-racist and feminist movements failing to advocate for the rights of Black women, according to new research published by the American Psychological Association.

New Lancaster study 'reimagines infertility'
New research from Lancaster University has identified the 'invisible infertile', a group of marginalized people missing from survey data sources because they do not fit neatly into popular notions of who is at risk of infertility. Around the world, the 'invisible infertile' includes racial and ethnic minorities, those with limited economic resources, those who do not have access to affordable healthcare, the LGBTQ community, persons with disabilities, and more often men than women.

Better mastery of heat flow leads to next-generation thermal cloaks
The idea of a thermal cloak, which is designed to hide heated objects without distorting the temperature outside, has long since fascinated scientists. Materials for such cloaks would need to offer zero thermal conductivity to help camouflage the heat. Now, Liujun Xu and colleagues from Fudan University, Shanghai, China, have explored a new mechanism for designing such materials, in a paper published in EPJ B. These findings could have implications for manipulating the transfer of thermal energy as a way to ultimately reduce heat waste. (2017-12-04)

Now you see me! New insect mimics dead leaves -- but sings loud enough for humans to hear
A new species of bushcricket which mimics dead leaves to the point of near invisibility and sings so loud humans can hear it has been examined for the first time using advanced technologies to reveal unusual acoustic properties of its wings. Scientists investigating the newly-described species, named Typophyllum spurioculis, found that when the males sing the entire wing resonates at the frequency of the call -- something which does not happen in other species of bushcrickets.
