A study of over 1,000 professionals shows that while AI makes managers’ messages more polished, heavy reliance can damage trust. Employees tend to accept low-level AI help, such as grammar fixes, but become skeptical when supervisors use AI extensively, especially for personal or motivational messages. This “perception gap” can lead employees to question a manager’s sincerity, integrity, and leadership ability. Tue, 12 Aug 2025 02:15:41 EDT https://www.sciencedaily.com/releases/2025/08/250811104226.htm https://www.sciencedaily.com/releases/2025/07/250718031218.htm In a groundbreaking UK first, eight healthy babies have been born using an IVF technique that includes DNA from three people—two parents and a female donor. The process, known as pronuclear transfer, was designed to prevent the inheritance of devastating mitochondrial diseases passed down through the mother’s DNA. The early results are highly promising: all the babies are developing normally, and the disease-causing mutations are undetectable or present at levels too low to cause harm. For families once haunted by genetic risk, this science offers more than treatment—it offers transformation.

In a new study using functional MRI, researchers uncovered two key brain regions that activate when people feel cognitively fatigued—regions that appear to weigh the cost of continuing mental effort versus giving up. Surprisingly, participants needed high financial incentives to push through challenging memory tasks, hinting that motivation can override mental fatigue. These insights may pave the way to treating brain fog in disorders like PTSD and depression using brain imaging and behavior-based therapies.

A study shows that this effect shapes how food prices respond to agricultural climate policies: While value-added components buffer consumer price changes in wealthier countries, low-income countries -- where farming costs dominate -- face greater challenges in managing food price increases due to climate policies.

The analysis finds that large-language models excel at making diagnoses from exam-style questions but struggle to do so from conversational notes. The researchers propose set of guidelines to optimize AI tools' performance and align them with real-world practice before integrating them into the clinic.
