Elon Musk’s next mission: To send 100 humans to Mars

-
Billionaire Elon Musk has revealed plans for a spaceship that could ferry up to 100 people to Mars. The SpaceX  boss posted images on Twitter of the “test hopper” prototype that is currently under construction in Texas.   He also responded to a flurry of questions from his followers about the spaceship and its   rocket engine   which is designed to carry a 150 ton payload into space. Following speculation from one user that the space craft will make use of stainless steal, Musk confirmed that it would use similar materials to the Atlas rockets first produced in the 1950s.  The entrepreneur shared the details following the successful launch of the Falcon 9 rocket, which lifted off from Texas on a separate mission to deliver a spy satellite into orbit.   He continued: “Actually, the only significant design element in common with early Atlas is stainless steel and we’re using a different alloy mix.” The SpaceX boss also said the Raptor rocket engine that would help launch the spacecraft had been “radically redesigned”. Musk said more details about Starship would be revealed early next year following a test flight of the prototype.   “I will do a full technical presentation of Starship after the test vehicle we’re building in Texas flies, so hopefully March/ April,” he tweeted.

E-bandage generates electricity, speeds wound healing in rats

Skin has a remarkable ability to heal itself. But in some cases, wounds heal very slowly or not at all, putting a person at risk for chronic pain, infection and scarring. Now, researchers have developed a self-powered bandage that generates an electric field over an injury, dramatically reducing the healing time for skin wounds in ...

Fathers Are Happier Than Mothers, Study Shows — And Here's Why

-

The third study compared fathers to mothers and their level of happiness while caring for their children. Fathers, it seems, are more likely to be happy while caring for their children than mothers. A 2019 study out of the University of California Riverside, highlights one more aspect in the divide between fathers and mothers, and more broadly, men and women. The research, a meta-analysis of three different studies, looked at the emotional health of 18,000 people and compared traits like well-being, happiness, episodes of depression, and stress. The first two studies within the research compared parents to childless people and found that fathers are happier than their child-free peers. The reason? Dads, more often than moms, report playing with their children while providing care. Now, let's unpack this a bit. We can assume, that of the 18,000 couples who took part in this research, many split household chores equally. But over recent years, much light has...

Your friends shape your microbiome — and so do their friends

Analysis of nearly 2,000 people living in remote villages in Honduras reveals who’s spreading gut microorganisms to whom. Friends share more than just food when they dine together.Credit: Getty A shared meal, a kiss on the cheek: these social acts bring people together — and bring their microbiomes together, too. The more people interact, the more similar the make-up of their gut microorganisms is, even if individuals don’t live in the same household, a study1 shows. The study also found that a person’s microbiome is shaped not only by their social contacts but also by the social contacts’ connections. The work is one of several studies2 that raise the possibility that health conditions can be shaped by the transmission of the microbiome between individuals, not just by diet and other environmental factors that affect gut flora. In the quest to understand what shapes a person’s microbiome, social interactions are “definitely a piece of the puzzle that I think has been missing until rec...
