Megafauna Extinction Driven Mainly By Climate Change, Not Humans

Samples of ancient DNA from fossils of megafauna like mammoths reveal that the extinction of large land mammals correlates more closely with warming climates than the arrival of humans. The researchers looked at these trends at an unprecedented evolution that allowed them to uncover strong evidence to the contrary of the prevailing theory that humans caused the demise of megafauna.

Gender Dysphoria Is Not Caused By Hormonal Imbalances, Study On Transgender Youth Finds

The claim that the transgender experience is a result of hormonal imbalances can be harmful to transgender people looking to gain acceptance for who they are. A new study that shows transyouth have hormone levels typical of the gender they were assigned at birth provides further evidence that such claims are unfounded.

A Robotic Car Controlled By A Bacterial Brain

By taking advantage of bacterial behavior, researchers were able to create a biological 'brain' for this robot. The bacteria actually make decisions for the robot, telling it where, when, and how quickly to move.

Scientists Grow Tiny Brain 'Organoids' In A Dish To Study Autism

Autism is a complex disorder with many associated features, and one trait observed in many cases of severe autism is an enlarged brain. To study how and why the brain develops differently in these cases, researchers used cells from autism patients to grow 'brain organoids' in a dish, mimicking the brains in embryos about 10 to 16 weeks old.
