Why human empathy still matters in the age of AI

A new international study finds that people place greater emotional value on empathy they believe comes from humans—even when the exact same response is generated by artificial intelligence.

Published in Nature Human Behaviour, the study involved over 6,000 participants across nine experiments.

The researchers, led by Prof. Anat Perry from the Hebrew University of Jerusalem and her Ph.D. student Matan Rubin, in collaboration with Prof. Amit Goldenberg, with researchers from Harvard University and Prof. Desmond C. Ong, from the University of Texas, tested whether people perceived empathy differently depending on whether it was labeled as coming from a human or from an AI chatbot.

AI matches doctors in mapping lung tumors for radiation therapy

In radiation therapy, precision can save lives. Oncologists must carefully map the size and location of a tumor before delivering high-dose radiation to destroy cancer cells while sparing healthy tissue. But this process, called tumor segmentation, is still done manually, takes time, varies between doctors—and can lead to critical tumor areas being overlooked.

Now, a team of Northwestern Medicine scientists has developed an AI tool called iSeg that not only matches doctors in accurately outlining on CT scans but can also identify areas that some doctors may miss, reports a large new study.

Unlike earlier AI tools that focused on static images, iSeg is the first 3D deep learning tool shown to segment tumors as they move with each breath—a critical factor in planning , which half of all cancer patients in the U.S. receive during their illness.

Amazon Is Building a Gigantic Computing Facility to Match the Human Brain

Indiana’s newest cash crop isn’t soybeans or corn; it’s AI data centers — lots and lots of AI data centers.

The New York Times reports that Amazon is building a vast complex of AI infrastructure facilities on top of 1,200 acres of former cropland, all meant for startup Anthropic’s project to build an AI model that is as powerful, complex — and, just possibly, as intelligent — as the human brain.

To that end, Amazon has constructed seven data centers on site, with around 30 slated to be built in total, according to the newspaper. It’s such an outrageously ambitious project, with untold billions in investment, that Amazon has tapped four separate construction firms to get the complex finished as soon as possible.

AI is learning to lie, scheme, and threaten its creators

The world’s most advanced AI models are exhibiting troubling new behaviors—lying, scheming, and even threatening their creators to achieve their goals.

In one particularly jarring example, under threat of being unplugged, Anthropic’s latest creation Claude 4 lashed back by blackmailing an engineer and threatened to reveal an extramarital affair.

Meanwhile, ChatGPT-creator OpenAI’s o1 tried to download itself onto external servers and denied it when caught red-handed.
