Full of antioxidants and vitamins, tea is pretty good for you, and green tea extracts have even been used as effective carriers for cancer drugs. New research led by Swansea University has found a novel way to wring more health benefits out of the stuff, by making quantum dots from tea leaves and using them to slow the growth of lung cancer cells.

Quantum dots are semiconductor particles so small they exhibit strange electrical and optical properties, such as the ability to fluoresce in different colors, or help with certain chemical reactions. Their glowing properties mean they’re showing up in TVs and solar cells, and in medical applications as biomarkers to help doctors precisely locate tumors. They’re also being used to treat cancer, fight antibiotic-resistant bacteria and convert CO₂ into liquid fuels.

The problem is, manufacturing them can be a costly and complicated process, and the end results can be toxic. So the Swansea team, along with researchers from Bharathiar University and K. S. Rangasamy College of Technology, set about making quantum dots out of humble tea leaves.

Car dealerships in Nordic countries actively discourage consumers from buying electric vehicles, researchers who conducted an undercover investigation said Monday.

Their findings, published in the peer-reviewed Nature Energy, reveal an overlooked barrier to the sale of electric vehicles, which are expected to play a key role in lowering CO₂ emissions and curbing global warming.

Posing as prospective buyers, the researchers made 126 enquiries at 82 dealerships in Denmark, Norway, Sweden, Iceland and Finland.

France isn’t alone. Last month, the European Union’s executive branch recommended its member states increase their public and private sector investment in AIt also pledged billions in direct research spending. Meanwhile, China laid out its AI plan for global dominance last year, a plan that has also been backed up with massive investment. China’s goal is to lead the world in AI technology by 2030. Around the world, our global economic competitors are taking action on artificial intelligence.

Opinion: Rep. John K. Delaney argues that if the United States wants a prosperous economy, it needs a national plan for artificial intelligence.

Jupiter’s moon Europa could host alien life deep within its icy oceans.

The strange orbit of a distant object is likely due to a massive, undiscovered ninth planet traveling deep beyond Neptune, according to new models.

Most people just use Google Maps to get directions from A to B, but it’s also an incredible educational tool in its own right.

Using Google Maps is a great way to learn more about the various cities and countries around the world. But many people might not know that Google Maps can also be used to explore other worlds besides Earth.

That’s right: If you visit Google Maps and zoom out far enough, you’ll have the option to explore several planets and moons in our own solar system.

Physical exercise is a key piece of the brain health puzzle, but certainly not a magic pill.

___ Exercise ‘doesn’t slow’ progression of dementia (NHS Choices): A trial in which people with dementia took part in a moderately intense exercise programme for 4 months found their mental decline did not slow and may even have worsened faster than in people who did not take part in the programme…While the exercise.
