NASA Webb micrometeoroid mitigation update

Micrometeoroid strikes are an unavoidable aspect of operating any spacecraft. NASA's James Webb Space Telescope was engineered to withstand continual bombardment from these dust-sized particles moving at extreme velocities, to continue to generate groundbreaking science far into the future.

Editorial examines challenges of automated facial-expression analysis

As automated facial-expression analysis, or AFEA, becomes increasingly able to recognize facial behavior in everyday life, it will become increasingly important to understand what causes the technology to work incorrectly, as well as anticipate problems that could arise when it does work correctly.

As New South Wales reels, many are asking why it's flooding in places where it's never flooded before

On Monday, residents of Eugowra in New South Wales had to flee for their lives. They had only minutes to get to higher ground—or their rooftops—to escape what's been dubbed an "inland tsunami" of water. This week, many other towns across western NSW faced renewed floods. For many people affected, the real shock is how unexpected it was—and how fast the water came. Their houses and land had...

Can a universal basic income help address homelessness?

Homelessness is an increasing problem across the developed world, and existing policy responses are failing to make an impact. In Australia, for instance, homelessness has increased despite growing investment in (predominantly crisis-oriented) specialist homelessness services.

Novel AI blood test detects liver cancer

A novel artificial intelligence blood testing technology has been used to successfully detect lung cancer in a 2021 study has now detected more than 80% of liver cancers in a new study of 724 people.

Scientists build nanoscale parapets, aqueducts, and other shapes

Scientists have developed a new way to guide the self-assembly of a wide range of novel nanoscale structures using simple layered block copolymers as starting materials. The work could help guide the design of custom surface coatings with tailored optical, electronic, and mechanical properties for use in sensors, batteries, filters, and more.

Legacy of a molecular dynamics trailblazer

Physicists explains how the theoretical chemist Martin Karplus and his team applied the approach of molecular dynamics simulation to a large biological molecule, a protein, deeply impacting biology and the physical sciences in the 20th and 21st centuries.
