Scientists use giant telescope on sea floor to study rays from space

Curtin University researchers are part of an international project that will use a huge underwater neutrino telescope at the bottom of the Mediterranean Sea to help explain some of the most powerful and mysterious events in the universe.

The mechanism of cellular migration mode switching

When faced with difficult terrain, off-road vehicles can switch from two- to four-wheel drive to keep moving forward. Similarly, cell migration can be driven either by protrusion-directed crawling, or by contractile pulling forces, but how the cell switches between these two methods remains a mystery.

All base units of measurement now tied to defined constants rather than physical objects

Scales aren't changing and the weather won't be noticeably different, but on May 20 the definitions that underlie what your scale and thermometer report—along with standard definitions used in chemistry and electronics—are undergoing a major overhaul. That's the date that a more-than-centuries-long process of standardizing measurements reaches its conclusion.

Optical device decomposes a beam into a Cartesian grid of identical Gaussian spots

A research team has developed a light beam device that could lead to faster internet, clearer images of space and more detailed medical imaging.

Superconductor's magnetic persona unmasked

In the pantheon of unconventional superconductors, iron selenide is a rock star. But new experiments by physicists have found the material's magnetic persona to be unexpectedly mundane.

Thinking outside the box: 'Seeing' clearer and deeper into live organs

Scientists using a unique approach have developed a new biomedical imaging contrast agent. They say the breakthrough overcomes a major challenge to 'seeing' deeper into live tissue, and opens the way for significant improvements in optical imaging technology.

Ultra-thin superlattices from gold nanoparticles for nanophotonics

Researchers are creating ultra-thin, highly ordered layers of spherical hydrogel beads that encapsulate gold or silver particles. These structures are of interest for applications in optoelectronics -- light-based information and communication technology -- and nanophotonics.

Room-temperature polariton nano-laser

Researchers have developed a polariton nano-laser operating at room temperature.

The way we define kilograms, meters and seconds changes today

We measure stuff all the time—how long, how heavy, how hot, and so on—because we need to for things such as trade, health and knowledge. But making sure our measurements compare apples with apples has been a challenge: how to know if my kilogram weight or meter length is the same as yours.

Meet the Mercury 13: Women Fight for Spaceflight

The Mercury 13 aced the same tests as male astronauts, but decades would pass before American women flew in space.
