In the solar system’s early days, a first Earth is thought to have been pulverised by a planet that scientists call Theia. We don’t know what it was made of or where it came from, only that it may have been the size of Mars. The powerful collision destroyed both planets so completely that scientists can only guess what they were like.
As a child, you almost certainly at one stage spent hours watching ants move about from their nest. Maybe you dropped a piece of food and watched as a group of ants came and picked it up, carrying it home in an impressive display of cooperation.
Most of us feel afraid when faced with a threat or danger, but people with phobias and anxiety feel overwhelming levels of fear in situations that are relatively harmless. Scientists want to moderate this response by using drugs to wipe out scary memories or by harnessing the power of heartbeats to improve therapy.
Nature is complex – often too complex for humans to see. But squint-controlled glasses that let people see 3D thermal images and a camera that can capture the inner workings of high-speed chemical reactions are helping to push the limits of human perception.
Giorgio Vallortigara didn’t set out to develop software that could detect whether babies have autism. A neuroscience professor at the University of Trento in Italy, his areas of expertise include animal cognition – he’s into the brains of honeybees, zebrafish and newly-hatched chicks.
Listening to someone speaking with a foreign accent makes human brains work harder which can lead to unintentional discrimination against people communicating in languages other than their own, new research suggests. But exposure to foreign accents can also change the way people speak, and over time, the ensuing accents can become new languages.
Identifying the chemical switches that turn different parts of our immune system on and off is opening up new avenues for treating diseases such as Parkinson’s, Alzheimer’s, cancer and rheumatoid arthritis – and potential new uses for discarded drugs, according to Professor Luke O’Neill, an immunologist at Trinity College Dublin, Ireland.
Most children are able to learn language almost effortlessly. But for those with communication disorders such as dyslexia, mastering their native tongue can be a challenge. Researchers are exploring how links with noise, language and motion could help diagnose problems earlier and pave the way for better treatment.
