Team paves the way for cancer immunotherapy demonstrating a novel technique that attacked tumors and inhibited cancers from spreading.

Summary: Team paves the way for cancer immunotherapy with a novel technique that attacked tumors and inhibited cancers from spreading. [This article first appeared on LongevityFacts. Author: Brady Hartman. ]

While cancer immunotherapy is a powerful treatment for some types of tumors, up until now, it hasn’t worked well on colon cancer.

However, a team of researchers in Barcelona just showed a new technique that allows the immune system to recognize and begin fighting the tumor in mice. The treatment was so successful that it inhibited the tumors from spreading, or metastasizing to other parts of the body – as cancer is prone to do. Moreover, for those cancers that had already spread, the treatment enabled the immune system to eliminate them quickly.

Wow!

Mount Sinabung spews volcanic ash as it erupts in Karo, North Sumatra, Indonesia on Feb. 19, 2018. The volcano on the Indonesian island of Sumatra has shot billowing columns of ash more than 16,000 feet into the atmosphere. Sinabung is one of the most active volcanos in Indonesia. It erupted in 2010 and has killed 17 people in eruptions in 2014 and another nine people in 2016.

Researchers have unlocked the genetic code behind some of the brightest and most vibrant colours in nature. The paper, published in the journal PNAS, is the first study of the genetics of structural colour — as seen in butterfly wings and peacock feathers — and paves the way for genetic research in a variety of structurally coloured organisms.

The study is a collaboration between the University of Cambridge and Dutch company Hoekmine BV and shows how genetics can change the colour, and appearance, of certain types of brightly-coloured . The results open up the possibility of harvesting these bacteria for the large-scale manufacturing of nanostructured materials: biodegradable, non-toxic paints could be ‘grown’ and not made, for example.

Flavobacterium is a type of bacteria that packs together in colonies that produce striking metallic colours, which come not from pigments, but from their internal structure, which reflects light at certain wavelengths. Scientists are still puzzled as to how these intricate structures are genetically engineered by nature, however.

The experiment was held near the isolated Israeli township of Mitzpe Ramon, whose surroundings resemble the Martian environment in its geology, aridity, appearance and desolation, the ministry said.

The participants were investigating various fields relevant to a future Mars mission, including satellite communications, the psychological affects of isolation, radiation measurements and search ing for life signs in soil.

Participant Guy Ron, a nuclear physics professor from the Hebrew University in Jerusalem, said the project was not only intended to look for new approaches in designing a future mission to the Red Planet, but to increase public interest.
