Bile duct cancer, also called cholangiocarcinoma, is a rare disease in which cancer cells form in the bile ducts. Learn more about this cancer and treatment options.
External and internal radiation therapy are used to treat bile duct cancer and may also be used as palliative therapy to relieve symptoms and improve quality of life.

The question is, can DEI proponents, who are already being marginalized, retool? Can they see themselves as champions who will guide humanity — regardless of peoples’ race, class, sexual orientation, gender, etc. — in this Fourth Industrial Revolution?
For, if political leaders are as unable as they seem to establish meaningful guardrails, AI will push those struggling to live their best lives (a right that should belong to all) to be thrown so far under the bus that roadkill will be more recognizable.
Combustion engines, the engines in gas-powered cars, only use a quarter of the fuel’s potential energy while the rest is lost as heat through exhaust.
Now, a study published in ACS Applied Materials & Interfaces demonstrates how to convert exhaust heat into electricity. The researchers present a prototype thermoelectric generator system that could reduce fuel consumption and carbon dioxide emissions—an opportunity for improving sustainable energy initiatives in a rapidly changing world.
Fuel inefficiency contributes to greenhouse gas emissions and underscores the need for innovative waste-heat recovery systems. Heat-recovery systems, called thermoelectric systems, use semiconductor materials to convert heat into electricity based on a temperature difference.

“Of these children, 85% are going to beat their cancer, but it’s a win at a cost,” says Armstrong. “We know that these kids will have shortened lifespans. They often die young of chronic diseases like heart disease, stroke or secondary cancers which present much earlier. And we discovered about a decade ago that this is because they’re ageing much faster than their chronological age.”
In particular, this is reflected not just in their biology, but in physical frailty. When Kirsten Ness, a physical therapist and clinical epidemiologist at St Jude, assessed a group of childhood cancer survivors aged 24–41, she noted that when it came to heart function, flexibility, respiratory capacity and range of motion, they resembled people decades older. “We showed that at 30, they have physiological frailty that resembles people in their 70s and 80s, and it’s getting worse over time,” says Ness.
The underlying cause of this is senescence, a state in which cells cease to continue dividing as normal, but instead simply linger, refusing to die. Because of this quality, senescent cells have sometimes been described as “zombie cells” and they are now regarded as a driving force and a reflection of ageing. Over the course of a lifetime, our bodies incur increasing amounts of damage which in turn makes many of our cells, distributed throughout our body, more likely to become senescent.
A robotic labor force.
Engineering companies in China have begun the process of starting full-scale mass production of humanoid robots in anticipation of a commercial boom in 2025. Companies such as Shanghai Zhiyuan Innovation Technology (AgiBot) and Shanghai Kepler Robot Company have already been testing the robots to optimize performance while reducing production costs.
Getting a specific screening — the coronary artery calcium (CAC) score — can help detect early signs of heart disease. Experts share the benefits of the test and how people can obtain it.
The neural basis of affect sharing is not fully understood. Here, the authors show that the anterior cingulate cortex (ACC) stably recruits neural ensembles encoding observational fear, specifically represented by affective responses to pain experience.
