Of all the advances made in theoretical physics in the last twenty years, I still have no doubt that the most impressive one is the so called Maldacena’s conjecture, the guess that the physics involved in some models of quantum gravity living in a very concrete 5-dimensional spacetime has a one-to-one correspondence with the physics […]

Salamanders may be getting shorter due to climate change Appalachian salamanders have gotten shorter in the past 50 years, possibly adapting to warmer, drier weather conditions. Researchers compared specimens they collected with those collected by museums from the same areas since 1957. They found that each generation of salamanders in several species grew 1% smaller […]

Last month, a lot of newspapers and websites have been promoting this article on Nature referring to a recent preprint uploaded by Stephen W. Hawking to the internet repository ArXiv. In this work, summarizing what he talked about in a conference given last August, the English physicist argue that, since event horizons, the definitory property […]

Paleontologists find evidence sauropods lived into Cretaceous period A sauropod belonging to the dinosaur group Titanosauria appears to have lived during the Early Cretaceous period providing evidence that sauropods lived beyond the Jurassic period. The remains of a juvenile Yongjinglong datangi were uncovered in northwestern China. International Science News Luhman 16B, where it rains liquid […]

Crocodiles, alligators use lures to attract prey Alligators and crocodiles use lures to entice prey, the first reported use of tools by reptiles. Researchers surveyed alligators and crocodiles at four sites in Louisiana for a year, noting that the creatures balancing twigs and sticks on their snouts to lure birds during nesting seasons. “Use of […]

Researchers try to figure out sea worm’s blue glow Researchers are a step closer to figuring out why a common sea worm glows blue on the shallow seafloors it calls home, thanks to a pair of experiments conducted by biologists at Scripps Institution of Oceanography. First, they found that the worm, unlike other light-emitting organisms […]

Todays story seems fairly simple: a magnetar has been seen spinning down. Impressive, isn’t it? You might be wondering what the hell is magnetar and why we should care about its spin. As it happens many times in science, we find nature behaving just the opposite to what we supposed it should. For scientists, this […]

Current safe sugar levels may not be so safe Female mice fed a diet with 25% added sugars died at twice the normal rate, while males were less likely to reproduce. That amount of sugar is considered a safe level for human consumption. “Added sugar consumed at concentrations currently considered safe exerts dramatic impacts on […]

Quantum field theory has been the paradigm of modern physics since it was formulated in the first half of the last century. It is based on the idea that everything in physics corresponds to the interaction of some fundamental fields that permeate all space and the excitations of which represent the particles we see in […]

Author: Henry Taylor, Associate Professor, Department of Philosophy, University of Birmingham What can you see right now? This might seem like a silly question, but what enters your consciousness is not the whole story when it comes to vision. A great deal of visual processing in the brain goes on well below our conscious awareness […]
