Artificial intelligence.
A novel system uses the discovery that the actinide berkelium, when oxidized, does not form negatively charged ions in solutions of high nitric acid, as other actinides do. This means an anion exchange column can separate berkelium by absorbing other actinides with negatively charged ions. The new method is much faster than the previously used approach, and is easier, cleaner, and yields purer product.

Weight regains is a common problem for weight loss individuals. A number of studies have shown that weight loss in overweight people results in a reduction in whole-body energy expenditure. This reduction in energy expenditure is disproportionate across tissues, known as energetic mismatch which primarily originates from lean tissue, thus increasing weight regain risk.

The researchers found that the specific material applied, and the specific application process used, impacted the properties of the coating, including how protective it was against corrosion. Their results were published recently in the scientific journal Frontiers in Metals and Alloys.
There is a need for new drugs. For example, many of the antibiotics that we have been using for a long time are becoming less effective. Chemists and pharmaceutical scientists are frantically searching for new active substances, especially those that can penetrate cell membranes, as these are the only ones that patients can take orally in the form of a tablet or syrup.
How can Marvel movie character Ant-Man produce such strong energy out of his small body? The secret lies in the “transistors” on his suit that amplify weak signals for processing. Transistors that amplify electrical signals in the conventional way lose heat energy and limit the speed of signal transfer, which degrades performance.
