Sci-Alert... One of the fascinating mysteries of Ancient Rome is the impressive longevity of some of their concrete harbour structures. Battered by sea waves for 2,000 years, these things are still around while our modern concoctions erode over mere decades. Now scientists have uncovered the incredible chemistry behind this phenomenon, getting closer to unlocking its long-lost recipe. As it turns out, not only is Roman concrete more durable than what we can make today, but it actually gets stronger over time. Researchers led by geologist Marie Jackson from the University of Utah have been chipping away at the mysteries of Roman concrete for years, and now they have mapped its crystalline ...

ScienceNews... Long typecast as the strong silent type, bones are speaking up. In addition to providing structural support, the skeleton is a versatile conversationalist. Bones make hormones that chat with other organs and tissues, including the brain, kidneys and pancreas, experiments in mice have shown. “The bone, which was considered a dead organ, has really become a gland almost,” says Beate Lanske, a bone and mineral researcher at Harvard School of Dental Medicine. “There’s so much going on between bone and brain and all the other organs, it has become one of the most prominent tissues being studied at the moment.” At least four bone hormones moonlight as ...

Sci-Alert... The more we find out about the bacteria that live in our gut, the more we're coming to realise how these microbiota could have an impact on every facet of our lives – and not just our physical health and well-being, but our thoughts and emotions too. A new study has identified associations between two kinds of gut microbiota and how they affect people's emotional responses, and the researchers say it's the first evidence of behavioural differences related to microbial composition in healthy humans. Up until now, most research looking into how gut organisms influence emotions has been conducted on animals, with scientists finding that the bacterial composition ...

Right now, the Sun is stirring up violent eruptions capable of wiping out the technology we are so dependent on, and new research has found that these blasts are even harder to predict than scientists first thought. The findings reveal that these coronal mass ejections hurl into Earth's atmosphere like a sneeze rather than a stream of bubble-like structures. The cloud-like eruptions are also strongly influenced by the solar wind, forcing researchers to reconstruct their space weather forecasting. "Up until now, it has been assumed coronal mass ejections move like bubbles through space, and respond to forces as single objects," said Mathew Owens, lead author from the ...

Apologies to the reader. Perhaps I wax tedious. But the question of intelligence is both interesting to me and great fun as talking about it puts commenters in an uproar. It is like poking a wasp’s nest when you are eleven. I am a bad person. Clearing the underbrush: Obviously intelligence is largely genetic–if it were cultural in origin, all the little boys who grew up in Isaac Newton’s neighborhood would have been towering mathematical geniuses–and obviously the various tests of intellectual function have, at least among testees of similar background, considerable relation to intelligence. Some individuals have more of it than others. For example, Hillary, a National ...

Astronomers observing the mysterious Kuiper Belt deep in space believe they may have detected signs of heretofore undiscovered large planet in our solar system. In a newly-published paper, the researchers say that they've spotted strange perturbations in the orbits of some space rocks lingering in the mass of icy debris and other materials which make up the Kuiper Belt. By working through calculations involving the tilt of these objects and other astronomical factors, they concluded that "something as massive as Mars would be needed to cause the warp that we measured." If this sounds familiar, that is because a similar discovery was made back in January of 2016, when ...

ScienceAlert... There are ten asteroids that the space organisation NASA said last month have been classified as "potentially hazardous" based on their size and their orbits in our Solar system. NASA has now identified 693 near-Earth objects thanks to the Wide-field Infrared Survey Explorer spacecraft that's been looking for potential threats to Earth since 2013. The organisation doesn't specify what kind of hazard these ten asteroids pose. But Earth has been hit by objects in the past, with devastating effects. Scientists largely agree that it was an asteroid or comet impact that started the chain of events that wiped out the dinosaurs around 60 million years ago. ...
