Predicting human crowds with statistical physics
For the first time researchers have directly measured a general law of how pedestrians interact in a crowd. This law can be used to create realistic crowds in virtual reality games and to make public spaces safer.
Bumblebees make false memories too
It's well known that our human memory can fail us. People can be forgetful, and they can sometimes also "remember" things incorrectly, with devastating consequences in the classroom, courtroom, and other ...
Drilling ancient African lakes sheds light on human evolution
How was human evolution and migration influenced by past changes in climate?
Disappearing lakes stoke megafauna debate
New research into central Australia's ancient lakes has found evidence that climate change contributed to the extinction of the continent's megafauna.
Image: Human endothelial cells experiment bound for ISS
Components of human endothelial cells stained for identification. In red is the 'actin' protein that allows the cells to move, adhere, divide and react to stimuli. In blue are the cell nuclei containing DNA.
Removing the communication barrier between humans and computers
The lifelong human imperative to communicate is so strong that people talk not only to other people but also to their pets, their plants and their computers. Unlike pets and plants, computers might one day ...
Evolving a bigger brain with human DNA
The size of the human brain expanded dramatically during the course of evolution, imparting us with unique capabilities to use abstract language and do complex math. But how did the human brain get larger ...
Ancient and modern cities aren't so different
Despite notable differences in appearance and governance, ancient human settlements function in much the same way as modern cities, according to new findings by researchers at the Santa Fe Institute and the ...
Neuroscientist takes scientific look at art of filmmaking
Why do so many of us cry at the movies? Why do we flinch when Rocky Balboa takes a punch, duck when the jet careens toward the tower in "Airplane," and tap our toes to the dance numbers in "Chicago" or "Moulin ...
Study identifies two biomarkers for lack of sleep
Focusing on the success of others can make us selfish
It is believed that the success of humans as a species depends to a large extent on our ability to cooperate in groups. Much more so than any other ape (or mammal for that matter), people are able to work ...
Scientists making progress with techniques that allow for seeing through opaque materials
Synthetic biology yields new approach to gene therapy
Bioengineers at The University of Texas at Dallas have created a novel gene-delivery system that shuttles a gene into a cell, but only for a temporary stay, providing a potential new gene-therapy strategy ...
Conserving for nature's sake or our own?
The value of nature in conservation may seem simple, straightforward and fundamental. Yet a persistent question arises: Should we conserve nature only for humans or also for its own sake as well?
