Cancer cells force normal cells to mimic viruses to help tumors spread, resist treatment

In a study that could explain why some breast cancers are more aggressive than others, researchers say they now understand how cancer cells force normal cells to act like viruses – allowing tumors to grow, resist treatment, and spread. The virus mimic is detected in the blood of cancer patients, particularly in cases of an aggressive type known as triple-negative breast cancer. Researchers say cracking the code of how this process works opens up the possibility of targeting this mechanism for treatment.

Complex gas motion in the centre of the Milky Way

Our solar system is located in the outer regions of the Milky Way, a disk-shaped galaxy with an approximate diameter of 100,000 light years. From Earth, its appearance can only be observed indirectly, by measuring positions and movements of stars and gas clouds. In addition to luminous stars, a substantial portion of the visible matter in our Milky Way is interstellar gas. Gas clouds in the so-called central molecular zone (CMZ) -- the innermost 1,500 light years of the Milky Way -- move on an elliptical central disk that has two spiral arms.

    Researchers have surveyed the environmentally protected area in Campinas, Southeastern Brazil, which has undergone several changes by human action, especially the implementation of condominiums, and revealed that more than one percent of dogs, as well as some opossums and insect species in the area carry the parasite responsible for the most dangerous form of leishmaniasis.

    One of the primary missions of neuroscience is to make connections between particular neurons in the brain and specific behaviors. Now a team of researchers has used computer-vision and machine-learning techniques in fruit flies to create behavior anatomy maps that will help us understand how specific brain circuits generate Drosophila aggression, wing extension, or grooming.

    Scientists have created comprehensive brain maps linking different groups of neurons to specific behaviors, using a machine-learning program that annotated more than 225 days of videos of flies -- a feat that would have taken humans some 3,800 years.

    Vaccines protect fetuses from Zika infection, mouse study shows

    Zika virus can cause severe brain damage in people infected before birth. A new study in mice shows that females vaccinated before pregnancy and infected with Zika virus while pregnant bear pups who show no trace of the virus. The findings offer the first evidence that an effective vaccine administered prior to pregnancy can protect vulnerable fetuses from Zika infection and resulting injury.
