The sprawling storm promised to deliver torrential rain across a wide swath of southern Japan.

If it's ever been your dream to spend 22 hours on a non-stop flight from Sydney to London, then good news: Airbus has announced the maiden flight of the world's longest-range airliner, the Airbus A350-1000ULR, with a range of almost 10,000 nautical miles.Continue ReadingCategory: Aircraft, TransportTags: Airbus, Qantas, Aircraft

In nature, there exist structures that are mirror images of each other but cannot be perfectly superimposed. These are known as chiral objects, derived from the Greek word for "hand," since left and right hands share the same relationship. Although similar in structure, chiral molecules exhibit different behaviors, and chirality is central to life itself. DNA has a twisted chiral structure, and living organisms prefer one handedness over the other. This distinction is equally important in drug design, materials science, and nanotechnology.

A new study published in the Journal of Raptor Research, titled "Factors Influencing Nestling Sex Ratios of Suburban and Rural Red-Shouldered Hawks, 2004–2016," finds that hawk parents prioritize producing female offspring when conditions are optimal. This means that higher quality territories could result in more females, offering biologists clues about habitat health, which is important intel as the species adapts to urban environments with increasing frequency.

New research from the University of St Andrews has discovered that insects who conceal themselves as leaves also use their leafy camouflage to amplify mating calls, making themselves more attractive to the opposite sex. The research published in Proceedings of the Royal Society B is the first demonstration of how impressive leaf mimicry can also be used to enhance the attractiveness of a sexual signal.

The same structures used for camouflage can also help these insects reproduce. The post Big wings and sweet songs: The mating lives of Panama’s katydids appeared first on Popular Science.

Researchers from the Faculty of Medical and Health Sciences (FCMS) at the Pontifical Catholic University of São Paulo (PUC-SP) in Sorocaba, in the interior of the state of São Paulo, Brazil, have developed a biomaterial containing jackfruit latex, pomegranate peel extract, and simvastatin (a statin-based medication) that shows promising efficacy in treating periodontitis.

Cornell researchers have developed a new way to create moiré patterns—atomic-scale structures that can give materials unusual quantum behaviors—without relying on the traditionally used difficult-to-control twisting and stacking methods. The study is published in the Proceedings of the National Academy of Sciences.

Bowerbirds in an Australian city use a range of human items—from glass and plastic to banknotes and even a pair of handcuffs—to impress females, shows new research in Royal Society Open Science. Male bowerbirds create an intricate tunnel of twigs called a bower, then gather colorful items to show to any females that visit.

New research reveals that resident forest birds avoid intensive clearcut areas, highlighting the need for more sustainable forestry practices.

An analysis of Quebec's forest inventory data developed by Concordia researchers reveals that the conifer population is on the rebound after decades of decline.

The long, puzzling dwarf planet Ceres, in reality the first named asteroid, has surface features that are much more complex than previously thought. Or at least that's the conclusion of a recent paper presented at the European Geosciences Union 2026 General Assembly in Vienna.
