Scientists pave the way for new culinary frontiers.

This E-tongue can identify four tastes – saltiness, sourness, astringency, and sweetness – in just a tiny bit of food, and uses deep-learning technology to understand taste. It even works well with different kinds of wines.

The E-tongue is like a super tool that can be used in different industries like food, drinks, makeup, and medicine, explained the researchers in a press release by Daegu Gyeongbuk Institute of Science & Technology (DGIST).

“The novel technology developed in this study is an electronic tongue system that integrates sensors and deep learning and measures complex flavors, and it is a sensor-deep-learning technology that can quantitatively evaluate taste, which was difficult in the past,” said Professor Kyung-In Jang from the DGIST Department of Robotics and Mechanical and Electronic Engineering.

In the Lord of the Rings, there was “one ring to rule them all.” Now, a team of researchers is developing their own single ruler, an approach to CAR T-cell therapy that could treat all forms and types of blood cancer.

In experiments in mouse models of different blood cancers, the treatment rapidly eliminated tumors, including in mice with acute myeloid leukemia (AML), a difficult-to-treat type of blood cancer for which researchers have struggled to develop effective immunotherapies.

There was also no evidence of serious side effects in the animals. And, finally—and distinctly from the standard approach to current CAR T-cell therapies—it provided the mice with a healthy supply of new blood cells.

On every count, nanoelectrofuel flow batteries appear to beat lithium-ion batteries for use in EVs and larger systems. Influit expects that its current generation of nanoelectrofuel, together with the entire ecosystem needed to produce, distribute, and recycle the fuel that the company is building around it, should cost $130/kWh when used in an EV. In comparison, lithium-ion batteries cost around $138/kWh. True, lithium-ion’s costs should drop below $100/kWh in a few years, but Influit expects its next-generation nanoelectrofuel to fall even further, to around $50 to $80/kWh. That next-gen system should have 5 times the energy density of present Li-ion systems.

Here’s what that means for an EV.

A typical EV battery today occupies about the same volume as would a flow battery with 400 liters of nanelectrofuel. If nanoparticles made up 30 percent of the weight of that fuel, the EV would have a range of only 105 km. Raise that to 40 percent, and the range would climb to 274 km. At 50 percent, it hits 362 km. And at 80 percent, it’s 724 km (450 miles). And that’s all assuming the flow battery’s tank remains the same size.

NEW YORK (AP) — Nearly three years after rioters stormed the U.S. Capitol, the false election conspiracy theories that drove the violent attack remain prevalent on social media and cable news: suitcases filled with ballots, late-night ballot dumps, dead people voting.

Experts warn it will likely be worse in the coming presidential election contest. The safeguards that attempted to counter the bogus claims the last time are eroding, while the tools and systems that create and spread them are only getting stronger.
