The holidays are in full swing and people are shopping, wrapping and packing to visit loved ones. Along with the extra fees for checked baggage and seat upgrades, some airlines are also considering weight-based pricing. A recent study looked at how people felt about weighing their baggage and themselves to help reduce emissions and found while over half of travelers are not keen about hopping on the scale, some would be open to the idea -- especially if it aligns with their own interests in the environment.

Novel research shows that a reduced neural response to receiving rewards in teens predicts the first onset of depression, but not anxiety or suicidality. This is independent of pre-existing depressive or anxiety symptoms, as well as age or sex, which are already strong risk factors for depression. The study is a step toward using brain science to understand and assess mental health risks.

Infertility affects an estimated 186 million people worldwide, with fallopian tube obstruction contributing to 11%-67% of female infertility cases. Researchers have developed an innovative solution using a magnetically driven robotic microscrew to treat fallopian tube blockages. The microrobot is made from nonmagnetic photosensitive resin, coated with a thin iron layer to give it magnetic properties. By applying an external magnetic field, the robot rotates, generating translational motion that enables it to navigate through a glass channel simulating a fallopian tube.
