NASA astronauts safely splash down after first commercial crew flight to space station

Two NASA astronauts splashed down safely in the Gulf of Mexico Sunday for the first time in a commercially built and operated American crew spacecraft, returning from the International Space Station to complete a test flight that marks a new era in human spaceflight. SpaceX’s Crew Dragon, carrying Robert Behnken and Douglas Hurley, splashed down

Artificial Intelligence to identify individual birds of same species

Humans have a hard time identifying individual birds just by looking at the patterns on their plumage. An international study involving scientists form the CNRS, Université de Montpellier and the University of Porto in Portugal, among others, has shown how computers can learn to differentiate individual birds of a same species. The results are published

Graphene can act as surfactant

New research into graphene flakes has discovered that the material can act as a surfactant, for the first time demonstrating how it can be a versatile 2D stabiliser ideal for many industrial applications from oil extraction to paper processing. Pristine graphene is completely water repellent, but the researchers found that at a particular size (below

A plot twist in pharmaceuticals: Single nanoparticles could pave the way for medicines on demand

For the first time, a single, twisted nanoparticle has been accurately measured and characterised in a lab, taking scientists one vital step closer to a time when medicines will be produced and blended on a microscopic scale. Physicists at the University of Bath who study materials on the nanoscale — that is, molecules 10,000 smaller

Construction: How to turn 36 seconds into USD 5.4 billion

A team of researchers from Aarhus University have, for the first time ever, linked 40 years of productivity data from the construction industry with the actual work done. The results show that productivity in the construction industry has been declining since the 1970s. The results also explain the decline and how to achieve far more

Plastic recycling from Europe is being dumped in Asian waters

New research from NUI Galway and the University of Limerick has for the first time quantified the volume of plastic from European countries (EU, UK, Switzerland and Norway) that contributes to ocean littering from exported recycling. While European countries have developed world-leading waste management infrastructure, 46% of European separated plastic waste is exported outside the

Could your computer please be more polite? Thank you

PITTSBURGH–In a tense time when a pandemic rages, politicians wrangle for votes and protesters demand racial justice, a little politeness and courtesy go a long way. Now researchers at Carnegie Mellon University have developed an automated method for making communications more polite. Specifically, the method takes nonpolite directives or requests — those that use either
