To swallow food, some sharks shrug their shoulders
https://www.sciencedaily.com/releases/2017/07/170718221849.htm
Sophisticated X-ray imaging technology has allowed scientists to see that to keep food moving down toward the digestive tract, bamboo sharks use their shoulders to create suction.

How CD44s gives brain cancer a survival advantage
https://www.sciencedaily.com/releases/2017/07/170718221843.htm
In the case of glioblastoma multiforme, the deadliest type of brain cancer, researchers have discovered that the molecule CD44s seems to give cancer cells a survival advantage. In the lab, eliminating this advantage by reducing the amount of CD44s resulted in cancer cells being more sensitive to the deadly effects of the drug erlotinib.

Making lab equipment on the cheap
https://www.sciencedaily.com/releases/2017/07/170718142945.htm
Laboratory equipment is one of the largest cost factors in neuroscience. However, many experiments can be performed with good results using self-assembled setups involving 3-D printed components and self-programmed electronics. Researchers have now created 'FlyPi' -- a low-cost imaging and microscope system for research, training and teaching.

At the cellular level, a child's loss of a father is associated with increased stress
https://www.sciencedaily.com/releases/2017/07/170718142938.htm
The absence of a father -- due to incarceration, death, separation or divorce -- has adverse physical and behavioral consequences for a growing child. But little is known about the biological processes that underlie this link between father loss and child well-being. In a new study, a team of researchers reports that the loss of a father has a significant adverse effect on telomeres, the protective nucleoprotein end caps of chromosomes.
