It may sound abstract, but distinctions between "native," "introduced" or "invasive" species can often be life or death. Species considered invasive in Australia—such as European rabbits and feral pigs—are often culled, while most native animals are generally left alone.
According to quantum electrodynamics, the theory describing interactions between light and electrically charged particles, a sufficiently strong electric field can, in principle, convert some of its energy into particles and their antimatter partners. A particle's antimatter partner has the same mass and, for electrically charged particles, the opposite electric charge.
As quantum computers grow more ambitious, many researchers believe the best way forward is to build them in multiple interconnected parts. In these modular designs, separate quantum processors are linked so they can work together as one larger machine. For this to happen, however, connections must carry fragile quantum information without destroying it.
Around 2,400 years ago, at Łysa Góra in Poland, a group of people took a bronze helmet, crushed it, broke it into pieces and threw it into a pit with iron adzes and a scythe. Such helmets are sometimes found in lavish graves of the Celtic warrior elite, from Champagne, France, to Dürrnberg, Austria.
A kerosene-based gel developed by Concordia researchers could make rocket and satellite fuels easier to store and control.
Among the ravenous carnivores and lumbering herbivores that roamed the Cretaceous landscape, another kind of dinosaur was evolving that started to eat something else: the plants that began to flower and produce fruit. The discovery by paleontologists from Stony Brook University, Royal Ontario Museum (ROM) and the North Dakota Geological Survey reveals that a new species, Infernogallus jamesi—a type of small oviraptorosaur—had chewing muscles for mashing soft food, making it the first known dinosaur that specifically ate fruit.
A research team has designed and synthesized a molecular cage with an internal cavity by connecting two curved π-conjugated molecules face-to-face at three points.
At a landmark Canadian trial focused on the government's obligations to fight climate change, the young plaintiffs suing Ottawa over alleged policy failures have sought to focus attention on their mental health.
Nearly 200 nations struck hard-fought agreements Friday at a U.N. biodiversity summit, but the outcome was accompanied by disappointment over missed opportunities to address humanity's destructive toll on nature.
