Usually the seismic effects of human activity are a mere distraction or nuisance for seismologists. “We think of anthropogenic noise as obscuring the natural signals from the planet that we’re interested in, be they earthquakes or other signals,” said earth scientist Zach Eilon of the University of California at Santa Barbara. So researchers tend to install seismometers far from sources of anthropogenic noise. But some stations are installed within cities, perhaps to monitor the earthquake threat – and these, Eilon said, are now supplying useful information about how human activity leaves a seismic trace. There is now an international effort, involving around 100 seismologists worldwide and coordinated by Thomas Lecocq of the Royal Observatory of Belgium in Brussels, to collect lockdown data. … [Read more...] about Why lockdown silence was golden for science

The asteroid, dubbed 52768 (1998 OR2), is estimated to measure between 1.8km - 4.1km in diameter. At the higher end of that estimate, it suggests the asteroid could be up to five times as big as the Burj Khalifa! … [Read more...] about Huge asteroid five times the size of world’s tallest building will pass Earth this week
“A very modest velocity change in the asteroid’s motion (only a few millimeters per second), acting over several years, can cause the asteroid to miss the Earth entirely. However, the trick is to gently nudge the asteroid out of harm’s way and not to blow it up. … [Read more...] about NASA says an asteroid three times the size of Big Ben will skim past Earth next week
It is true hormones, lifestyle factors such as stress, and our diets are interconnected. But some aspects carry more weight than others. Certain hormones involved in food metabolism, like insulin, are affected by what we eat – slow-release carbs help prevent the insulin peaks you get with sugar. As for fat loss, some hormones, such as leptin, are thought to regulate the amount of fat stored in the body, says, Madeline Burke at Bristol University. “However there has been no concrete evidence so far that shows by eating certain foods the levels of these hormones can be controlled.” Avoiding hormone-fed meat makes sense though. “There is sound scientific basis to say if you have too much oestrogen-injected beef or what have you, that could influence your body,” says Professor Giles Yeo at the University of Cambridge. Not so for GM. “There are many ways of genetically modifying foods, so to say GM items are bad is a naive, dangerous thing to say.” … [Read more...] about Diets: is there any science behind the latest fad regimes?
WILL YOUR JOB BE TAKEN BY A ROBOT? PHYSICAL JOBS ARE AT THE GREATEST RISK Physical jobs in predictable environments, including machine-operators and fast-food workers, are the most likely to be replaced by robots. … [Read more...] about A car-building robot is being adapted to conduct up to 700 socially distanced lab-based Covid-19 experiments a WEEK
