Researchers at UT Southwestern Medical Center at Dallas have shown that some long-term breast-cancer survivors may have innate mechanisms to keep breast cancer at bay.
Their findings, published in the December issue of Clinical Cancer Research and available online, show that one-third of the longtime disease-free patients in the study had circulating tumor cells (CTCs). The presence of CTCs is often associated with a higher risk of recurrence if they are found soon after a mastectomy. The UT Southwestern discovery that CTCs can be found in patients up to 20 years after mastectomy is notable because these patients have a very low risk of recurrence. After 20 years, the risk of recurrence rises to 20 percent of survivors, and scientists are still unsure why.
"Dormancy is a mysterious phenomenon that occurs in certain types of cancer," said Dr. Jonathan Uhr, lead author of the study and professor in the Cancer Immunobiology Center and of microbiology and internal medicine. "The term refers to a recurrence of cancer long after the tumor has been removed."

World first experiments on sensor that may revolutionise everything from medical devices to unmanned vehicles
The new sensor - capable of detecting vibrations of living cells - may revolutionise everything from medical devices to unmanned vehicles.
Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
Just in time for Christmas, a Mars-analogue mission in Morocco, coordinated by the Robotics Innovation Center of the German Research Center for Artificial Intelligence (DFKI) as part of the SRC project FACILITATORS, has been successfully completed. SRC, the Strategic Research Cluster on Space Robotics Technologies, is a program of the European Union to support research and development in space technologies. From mid-November to mid-December 2018, a team of more than 30 scientists from 11 countries tested technologies for future exploration of Mars and Moon in the desert of the Maghreb state.
Close to the border with Algeria, the Erfoud region in Morocco – known to tourists for its impressive sand dunes – offered ideal conditions for the four-week...
