Suicide molecules kill any cancer cell

Thu, 19 Oct 2017 00:00:00 EDT

(Northwestern University) A super assassin hidden in every cell forces the cell to commit suicide if it becomes cancerous, reports a new study, the first to identify molecules to trigger a fail-safe mechanism that may protect us from cancer. The mechanism -- RNA suicide molecules -- can potentially be developed into a novel form of cancer therapy. Cancer cells treated with the RNA molecules never become resistant to them because they simultaneously eliminate multiple genes that cancer cells need for survival.



Launch of the 'Alliance of Severo Ochoa Centres and Maria de Maeztu Units of Excellence'

Specialized communication narratives help couples deal with miscarriage

Thu, 19 Oct 2017 00:00:00 EDT

(University of Missouri-Columbia) Anywhere from 10 to 25 percent of clinically recognized pregnancies end in loss, according to the American Pregnancy Association, making miscarriage a socially significant health issue. A recent University of Missouri study examined how men also have to cope with their partner's miscarriage and how married couples can use 'communicated perspective-taking' to cope. The findings could help couples cope with miscarriage while also informing practitioners who treat anxiety and stress.



Fundamental research enhances understanding of major cancer gene

Thu, 19 Oct 2017 00:00:00 EDT

Cleaning up? Not without helpers

Thu, 19 Oct 2017 00:00:00 EDT

(University of Freiburg) Freiburg scientists explain assembly and transport function of 'old' calcium pumps by 'new' partner proteins.



Moonshot grant will help researchers see two of cancer's key food sources at once

Thu, 19 Oct 2017 00:00:00 EDT

(University of Pennsylvania School of Medicine) Imagine trying to take a picture of a runner, but only being able to see her feet. If you could see her whole body, you'd get the full picture of how she uses both legs to put one foot in front of the other to reach top speed. That's the idea behind a cancer imaging project that just received $1.4 million in funding from the National Institutes of Health.



ERC, Ca' Foscari wins two grants

Thu, 19 Oct 2017 00:00:00 EDT

(Università Ca' Foscari Venezia) Ca' Foscari University of Venice won two ERC Starting Grants as a host institution specifically chosen by the researchers for the first time, with a total fund of about 3 million euros.



'The father of the 2 degrees limit': Schellnhuber receives Blue Planet Prize

Thu, 19 Oct 2017 00:00:00 EDT

(Potsdam Institute for Climate Impact Research (PIK)) Hans Joachim Schellnhuber is the Director of the Potsdam Institute for Climate Impact Research (PIK), a member of the Leibniz Association. The Blue Planet Prize honors outstanding thinkers who help to meet challenges of planetary dimensions. It is awarded by the Asahi Glass Foundation and handed over in presence of Japan's Imperial Prince and Princess. Schellnhuber received the prize for establishing a new field of science, Earth System Analysis, and introducing most influential concepts including the notion of tipping elements in the climate system.
