Die neue Batterie von XNRGI verspricht 1.100 Kilometer Reichweite für Elektroautos. Zugleich ist der Akku leichter, günstiger und sicherer — wie geht das?
Who knew?
Not only are the batteries eco-friendly, but they are powerful as well. The researchers found a way to make them last longer and provide more electricity batteries by using silicon anodes — an electrode through which the current enters into an electrical device — instead of traditional graphite.
“Today graphite is used as the main commercial material for fabricating the anode electrodes,” Cengiz Ozkan, a professor of mechanical engineering at UC Riverside explained.
A deadly outbreak of “superbug” salmonella sprung up in the US late last year. While this is certainly not the first time drug-resistant bugs have been found in the US, the outbreak marks yet another milestone on the road to a future without antibiotics.
Over 250 people across 32 states fell sick with a strain of Salmonella that’s resistant to multiple antibiotics between June 2018 and March 2019, according to a recent Morbidity and Mortality Weekly Report from the US Centers for Disease Control and Prevention (CDC). At least two people died from the infection, and a further 60 cases were so severe that they required hospitalization.
The outbreak of antibiotic-resistant Salmonella infections was linked back to beef bought in the US and a “Mexican-style soft cheese” obtained in Mexico. They found that the strain didn’t respond to ciprofloxacin and had “decreased susceptibility” to azithromycin, two of the main antibiotic drugs used to treat Salmonella infections. The unusual strain – known as Salmonella enterica serotype Newport – emerged no later than 2016 and is still continuing to spread among cattle.
It would be much easier to escape Earth’s gravity if you could skip the energy-intensive rockets.
That’s the idea behind the Spaceline, a newly-proposed type of space elevator that would link the Earth and the Moon in a bid drastically cut the cost of space travel.
Described in research published to the preprint server ArXiv by researchers at Columbia University and Cambridge University, the Spaceline would be tethered to the surface of the Moon and dangle down into geostationary orbit around the Earth like a plumb bob, waiting for astronauts to latch on and ride into the cosmos. The proof-of-concept paper found that the Spaceline could be constructed out of materials that exist today, raising the possibility of easier space travel and perhaps even orbital settlements.
When British futurist James Lovelock looks to the future, he doesn’t see humans ruling the Earth.
“Our supremacy as the prime understanders of the cosmos is rapidly coming to end,” he wrote in his new book “Novacene,” according to NBC News. “The understanders of the future will not be humans but what I choose to call ‘cyborgs’ that will have designed and built themselves.”
What Is Quantum Gravity?
Posted in particle physics, quantum physics, space
Gravity was the first fundamental force that humanity recognized, yet it remains the least understood. Physicists can predict the influence of gravity on bowling balls, stars and planets with exquisite accuracy, but no one knows how the force interacts with minute particles, or quanta. The nearly century-long search for a theory of quantum gravity — a description of how the force works for the universe’s smallest pieces — is driven by the simple expectation that one gravitational rulebook should govern all galaxies, quarks and everything in between.

In the past several months, the issue of ensuring a truly equal future for women in society has risen up the agenda of global challenges – whilst at the same time indicators suggest the actual gap is growing globally. From harassment and #metoo to #timesup and the rights to equal pay and equal access in education, the workplace, and the boardroom, women have been succeeding in spotlighting the issues and arguing for their rights. So, as we look to the future, some fundamental questions arise: What is the future of women? Are women’s futures different from men’s futures? How do we proceed in the coming years to embed a gender equality mindset while accounting for the unique challenges women face?
This article draws on insights from our recent book – The Future Reinvented – Reimagining, Life, Society and Business to explore how business and society can adjust to ensure a more positive future for women, focusing on what we consider to be critical agenda issues. We conclude with our advice and dreams for the future of women.
