Cancers like melanoma are hard to treat, not least because they have a varied bag of tricks for defeating or evading treatments. A combined research effort by scientists at the Weizmann Institute of Science and researchers in the Netherlands Cancer Institute in Amsterdam and the University of Oslo, Norway, shows exactly how tumors, in their battles to survive, will go so far as to starve themselves in order to keep the immune cells that would eradicate them from functioning.

Prime Minister Binyamin Netanyahu and Health Minister Yuli Edelstein received the first doses of the Pfizer coronavirus vaccine in Israel on Motzoei Shabbbos at an event that was live-streamed as part of the campaign to encourage the public to get the vaccine.
“It’s a small shot for a person and a huge step toward the health of us all,” the prime minister said.
They were inoculated at Sheba Medical Center, Tel Hashomer by the prime minister’s doctor, Dr. Zvi Herman Berkowitz.

Comments Off on The Mass of Manmade Stuff Now Equals the Planet’s Biomass
The mass of human-produced materials, such as concrete, steel and asphalt, has grown to equal the biomass of all life on the planet, according to a study from the Weizmann Institute of Science in Israel.
Humans are adding new buildings, roads, vehicles and products at a rate that doubles every 20 years. This “concrete jungle” is predicted to weigh more than twice the total biomass of living things by 2040.
Study shows how melanomas assist T cells from identifying and killing tumor cells
Cancers like melanoma are hard to treat, not least because they have a varied bag of tricks for defeating or evading treatments.
Now, a combined research effort by the Weizmann Institute of Science, the Netherlands Cancer Institute in Amsterdam, and the University of Oslo shows exactly how tumors, in their fight to survive, will go so far as to starve themselves in order to keep the immune cells that would eradicate them from functioning. The work was published in
Nature.
The immunotherapies currently administered for melanomas work by removing obstacles that keep immune cells called T cells from identifying and killing tumor cells. Recent research suggested that, in melanoma, another blocker – one that stops IDO1, an enzyme that is overproduced by cancer cells – could also assist the T cells.
