Designing the trajectory of microsatellite swarms from the macro-micro perspective
As an emerging multi-satellite cooperative flight mode, the microsatellite swarm has become an important future research issue for distributed space systems. It offers low cost, rapid response, and collaborative decision-making. To address the coordination of swarms for autonomous agents, a probabilistic guidance approach has been investigated, which contained sub-swarms with different mission...
Along the Missouri river banks, one turtle thrived while the other declined
Two activities—harvesting turtles for food and riverside development—in Southern Missouri sharply reduced the number of northern map turtles in one river. When that happened, a longtime competitor moved in, according to 50 years of data.
Cosmologist Katie Mack explores scenarios for the end of the universe
The scientific consensus is that the universe was probably born in The Big Bang — the beginning of time and space. It's far less certain how the universe will end. Theoretical astrophysicist Katie Mack outlines the possible fates of the universe in her book, The End of Everything (Astrophysically...
Will there be a Covid winter wave in the UK? Here’s what the scientists think
Unlike previous waves fuelled by variants such as Alpha and Delta, the picture now is more complexAs the UK rides a new wave of Covid, we take a look at the variants causing infections, and what the future may hold. Continue reading...
Soil’s Power as a Climate Solution Has Often Been Overlooked. Until Now
More and more companies are relying on regenerative agriculture—based on old farming practices—to help maintain and restore soil health
Why being rude to the waiter (or other staff) is the worst strategy
After James Corden was accused of being ‘nasty’, psychologists explain why rudeness doesn’t payWhether it is clicking their fingers at the waiter, talking loudly on their phone or letting the kids go feral, there are few things as unappealing as a rude dining companion in a restaurant. But mistreating the staff is perhaps the cardinal sin of eating out, and has long been seen as indicative...

Researchers have shown that pain experienced by patients during medical treatments can be considerably alleviated by holding and experiencing the motions of a soft furry robot. Based on measures of pain, fear, and biomarker collection, the researchers believe that the robot can improve patient experience.
Discovery could dramatically narrow search for space creatures

An Earth-like planet orbiting an M dwarf -- the most common type of star in the universe -- appears to have no atmosphere at all. This discovery could cause a major shift in the search for life on other planets.
After 30 years -- new guidelines for weight-loss surgery
- ScienceDaily
- 22/10/21 15:37
Authorities on bariatric and metabolic surgery have issued new evidence-based clinical guidelines that among a slew of recommendations expand patient eligibility for weight-loss surgery and endorse metabolic surgery for patients with type 2 diabetes beginning at a body mass index (BMI) of 30, a measure of body fat based on a person's height and weight and one of several important screening...

Ever wonder what happens to the rubber tread that wears off a vehicle's tires? New modelling suggests an increasing amount of microplastics -- fragments from tires and roadways -- are ending up in lakes and streams.
The Download: Starlink’s satellite signals, and joyless tech
This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology. Starlink signals can be reverse-engineered to work like GPS—whether SpaceX likes it or not For years, Todd Humphreys has been trying to persuade SpaceX to tweak its Starlink constellation to also offer ultra-precise…

The secret behind spectacular blooms in world's driest desert
The Atacama desert, which stretches for approximately 1,600 km along the western coast of the cone of South America, is the driest place on Earth. Some weather stations there have never recorded rainfall throughout their existence. But it's far from barren: many species live here that occur nowhere else, adapted to its extreme conditions.
Starlink signals can be reverse-engineered to work like GPS—whether SpaceX likes it or not
Todd Humphreys’s offer to SpaceX was simple. With a few software tweaks, its rapidly growing Starlink constellation could also offer ultra-precise position, navigation, and timing. The US Army, which funds Humphreys’s work at the University of Texas at Austin, wanted a backup to its venerable, and vulnerable, GPS system. Could Starlink fill that role?
