Forcing cancer cells to die can alert the immune system to enhance anti-tumor attack

Unlike accidental cell death, some cells can actively decide to die through a controlled process. This is called programmed cell death and can occur in different forms, including apoptosis and necroptosis. Cells use this process when they are damaged, stressed, becoming cancerous, or infected by harmful microbes. This self-destruction mechanism helps to protect the body, but it is also involved in many diseases, such as infections, inflammatory conditions and cancer.

A major problem in cancer is that some tumors and cancer cells learn how to avoid apoptosis, allowing them to survive when they should die. This resistance can make cancer treatments less effective, especially in advanced or spreading (metastatic) cancers.

Japan space probe skims asteroid in test for planetary defense

This high-resolution view of Dimorphos was created by combining the final 10 full-frame images obtained by DART’s Didymos Reconnaissance and Asteroid Camera for Optical navigation (DRACO) and layering the higher-resolution images on top of the lower-resolution ones. Dimorphos is oriented so that its north pole is toward the top of the image. Credit: Public Domain

A Japanese space probe performed a flyby of a near-Earth asteroid on Sunday in a test mission for technology that could help protect the planet from space rocks.

The fridge-sized Hayabusa2 was due to fly within 800 meters (0...

Some agentic AI browsers may come with major cybersecurity risks

Some agentic AI browsers come with major cybersecurity risks, study finds

In the last year or so, artificial intelligence companies have rolled out a spate of web browsers equipped with AI agents. A user might ask one of these agents to plan a vacation, and it will open browser tabs to research routes and restaurants, then make reservations and add events to the user’s calendar. How well it does any of this varies.

New research from the University of Washington found that the most powerful of these browsers also open users up to significant cybersecurity risks...

Ovaries may take on job in immune system after their tenure as reproductive organs

Post-menopause ovaries transform to join the immune system after their tenure as the reproductive organ

For most women, the body begins to change dramatically in their 40s or 50s. This transition, known as menopause, is defined as 12 consecutive months without a menstrual period, marking the end of the reproductive years. While researchers are aware of the functions the ovaries perform during active reproductive years, what happens to the organ after menopause is largely a mystery.

A recent study in Molecular Human Reproduction investigated what happens to the ovary in mice after it stops producing eggs, a period known as the post-reproductive stage, similar to menopause in humans.

Researchers found th...
