The ‘big thuggish’ invaders have doubled in number over the past 15 years
Making thin films out of semiconducting materials is analogous to how ice grows on a windowpane: When the conditions are just right, the semiconductor grows in flat crystals that slowly fuse together, eventually forming a continuous film. This process of film deposition is common for traditional semiconductors like silicon or gallium arsenide — the basis of modern electronics — but scientists are now pushing the limits for how thin they can go. They have demonstrated a way to create a new kind of semiconductor thin film that retains its electrical properties even when it is just atoms thick. —> Read More
In a rolling, outdoor field, full of lumps, bumps and uneven terrain, researchers have successfully field-tested for the first time the locomotion abilities of a two-legged robot with technology that they believe heralds the running robots of the future. —> Read More
Edward O Wilson made his name by arguing that two apparently disparate things – human society and the natural world – are governed by the same principles. Sean B Carroll made his name by unifying the study of humans and animals, showing that development in both is driven by the same fundamental molecular and genetic processes. So what happened when these two scientists were brought together? They decided to unify all of biology.
Carroll visited Wilson’s office at Harvard University for a free-ranging, hours-long chat. It covered concerns for the future and reminiscing about the past – and morphed into an idea for a global campaign to unite biologists behind the common cause of saving the natural world, a prerequisite for understanding it.

A new test has been developed to predict sudden cardiac death in hemodialysis patients in whom such forecasts were previously impossible. The test uses a combination of nuclear medicine, C-reactive protein and electrocardiogram (ECG). Researchers found that patients with 2 or 3 abnormal measures were at 145 times increased cardiac risk. —> Read More
Young people are aware of the risks of cyberbullying but perceive others as being more at risk than themselves. Young women are more vulnerable to this perception than young men. —> Read More
English is now the language we all use to communicate science. But while it may feel inevitable, the domination of English is very recent and may be down to geopolitics and other accidents, argues a new book
According to new research from the University of California, Irvine, and the University of Nevada, exposure to galactic cosmic rays may have long-term adverse consequences to cognition throughout life; and performance decrements, memory deficits, and loss of awareness and focus during spaceflight may affect mission-critical activities. As NASA prepares for the first manned spaceflight to [...] —> Read More
A group of unusual giant black holes may be consuming excessive amounts of matter, according to a new study. This finding may help astronomers understand how the largest black holes were able to grow so rapidly in the early Universe. —> Read More
