A rapid evolutionary "arms race" between bacteria and the killer viruses they contain has been observed by a UNSW-led team of scientists in a sophisticated genetic study of the micro-organisms.
When life on Earth was first getting started, simple molecules bonded together into the precursors of modern genetic material. A catalyst would have been needed, but enzymes had not yet evolved. One theory is that the catalytic ...

It may be 350 kilometers (215 miles) above Earth and a place that only a privileged few will ever visit, but the International Space Station is crucial to advances in science, health and technology, experts say.
(Phys.org) —Harnessing the power of both the Hubble Space Telescope and the citizen science project Galaxy Zoo, scientists from the University of Portsmouth have found that bar-shaped features in spiral galaxies accelerate ...
A 12-year study of massive stars has reaffirmed that our Galaxy has four spiral arms, following years of debate sparked by images taken by NASA's Spitzer Space Telescope that only showed two arms.
Need a hand lifting something? A robotic device invented by University of Pennsylvania engineering students can help its wearer carry an additional 40 pounds (18 kilograms).
