Is the End of the World Really Nigh?
Look through the lens of science and “the end” becomes much more interesting.

Beloved Immortals: Science, Miracles and ‘Jellyfish Time’
What is biological immortality? To be fair, it’s not the promise of a paradisiacal garden. Neither is it the ultimate, or final, defeat of death. Instead, biological immortality has to do with aging. An organism that is biologically immortal does not age. We primarily age (the theory goes) because the cells that comprise us age….
A More Human Artificial Brain
The latest attempt to build machines that can learn to recognize objects or even develop cognitive skills is caled Spaun. Its full name is the Semantic Pointer Architecture Unified Network, but Spaun sounds way more epic. It’s the latest version of a techno brain, the creation of a Canadian research team at the University of…
Mind-Reading Scan Locates Site of Meaning in the Brain
Meanings of words can be hard to locate when they are on the tip of your tongue, let alone in the brain. Now, for the first time, patterns of brain activity have been matched with the meanings of specific words. The discovery is a step forward in our attempts to read thoughts from brain activity…
Why Our Brains Love Origins
We like to know where things come from. We like stories. We like nice tales. We need our myths, our origins, our creations. So uncomfortable is it for us if something doesn’t have a cause that we strive to determine one, one way or the other, even absent the necessary evidence. Psychologist Tania Lombrozo argues…
Science and the Fight Against Hunger
Although the world produces enough food to feed everyone, two million children die of malnutrition every year. Food insecurity has become a symbol of inequity and remains the most crippling consequence of poverty. Campaigners for food security must include science in their goals — and in return scientists need to heed wider concerns around solutions….
Mouse Brain Cells Can Live Years Longer Than The Mice They Came From
In a new study from the Proceedings of the National Academy of Sciences, mouse brain cells implanted into rats survived as long as the rats did, double the average mouse lifespan. This runs contrary to one theory of aging that holds that our life spans are genetically determined, and cells in our body will die…
