Childhood adversity may blunt brain development rather than speed it up
A new study published in Developmental Cognitive Neuroscience sheds light on how early exposure to family-related stressors, such as harsh parenting, family conflict, and unsafe neighborhoods, impacts brain development. Researchers found that children exposed to these threats showed distinct patterns…
How physics moves from wild ideas to actual experiments
Neutrinos are some of nature’s most elusive particles. One hundred trillion fly through your body every second, but each one has only a tiny chance of jostling one of your atoms, a consequence of the incredible weakness of the weak…

Catapulting pollen helps this flower beat out its rivals
Some flowers may be using their pollinators as battlegrounds. Their secret weapon: built-in pollen catapults that help them outcompete rival flowers. In Brazil, red flowers called Hypenia macrantha have both male and female reproductive organs. To avoid mating with themselves,…
Scientists Say: Rocket propellants
Rocket propellants (noun, “Rah-kit Pro-PELL-ents”) Rockets need two things to propel them forward. One is fuel. The other is a source of oxygen, or an oxidizer, to help burn that fuel. Together, fuels and oxidizers are known as rocket propellants.…
When GPS fails, cellphone signals could come to the rescue and safely navigate planes instead
A safety net of balloon-mounted sensors listening for satellites and cell towers could save lives if an airplane’s GPS signals were to get jammed or disrupted.
