Recycling spent lithium-ion batteries plays a significant role in alleviating the shorting of raw materials and environmental problems. However, recycled materials are deemed inferior to commercial materials, preventing the industry from adopting recycled materials in new batteries.

Now, researchers at Worcester Polytechnic Institute (WPI) in Massachusetts have demonstrated that the recycled materials from used lithium-ion batteries can outperform new commercial materials, making the recycled materials a potentially green and profitable resource for battery producers. Led by Yan Wang, professor in the Department of Mechanical and Materials Engineering, the team of researchers used physical tests, imaging, and computer simulations to compare new cathode materials recovered from old electric vehicle batteries through a recycling process, which is being commercialized by Battery Resourcers Inc. of Worcester.

The technology involved shredding batteries and removing the steel cases, aluminum and copper wires, plastics, and pouch materials for recycling. Researchers then dissolved the metals from those battery bits in an acidic solution. They by tweaking the solution’s pH, the team removed impurities such as iron and copper and recovered over 90% of three key metals – nickel, manganese, and cobalt. The recovered metals formed the basis for the team’s cathode material.

Forget about He Jiankui, the Chinese scientist who created gene-edited babies. Instead, when you think about gene editing you should think of Victoria Gray, the African-American woman who says she’s been cured of her sickle-cell disease symptoms.

This week in London, scientists are gathering for the Third International Summit on Human Genome Editing. It’s gene editing’s big event, where researchers get to awe the audience with their new ability to modify DNA—and ethicists get to worry about what it all means.

The field equations of Einstein’s General Relativity theory say that faster-than-light (FTL) travel is possible, so a handful of researchers are working to see whether a Star Trek-style warp drive, or perhaps a kind of artificial wormhole, could be created through our technology.

But even if shown feasible tomorrow, it’s possible that designs for an FTL system could be as far ahead of a functional starship as Leonardo da Vinci’s 16th century drawings of flying machines were ahead of the Wright Flyer of 1903. But this need not be a showstopper against human interstellar flight in the next century or two. Short of FTL travel, there are technologies in the works that could enable human expeditions to planets orbiting some of the nearest stars.

Certainly, feasibility of such missions will depend on geopolitical-economic factors. But it also will depend on the distance to nearest Earth-like exoplanet. Located roughly 4.37 light years away, Alpha Centauri is the Sun’s closest neighbor; thus science fiction, including Star Trek, has envisioned it as humanity’s first interstellar destination.

Brave new world let’s create happiness for everyone by putting microelectrode arrays in our brains but be careful not to create a situation like death by ecstacy by Larry Niven.

In the brain, pleasure is generated by a handful of brain regions called, “hedonic hotspots.” If you were to stimulate these regions directly, you would likely feel pleasurable sensations. However, not all of the hedonic hotspots are the same–some generate the raw sensations of pleasure whereas others are responsible for consciously interpreting and elaborating on the raw pleasure produced by the other hotspots. In this video, in addition to exploring the neuroscience of pleasure, we’ll see how understanding pleasure, happiness, meaning, and purpose can help us live better lives.

Scientists Believe, ‘Organoid Intelligence’, Is the Future of Computing. CNN reports that as part of a new field called “organoid intelligence,” a computer powered by human brain cells could shape the future. Organoids are lab-grown tissues capable of brain-like functions, such as forming a network of connections. Brain organoids were first grown in 2012 by Dr. Thomas Hartung, a professor of environmental health and engineering, by altering human skin samples.
