Brazilian researchers have identified activity against Xanthomonas citri in 29 fungi isolated from samples collected in Antarctica. One of the compounds inhibited reproduction of the bacterium by up to 98 percent. The process of purifying and submitting bioactive compounds to toxicological tests is expected to be concluded no later than 2019.

Brasilestes stardusti lived around 70 million years ago and was named after Ziggy Stardust, the singer's iconic persona. Description was based on a fossilized tooth. It's the first indication that placental mammals and dinosaurs co-existed in South America. For scientists, fossil features showed similarities with another prehistoric mammal found in India, suggesting both shared a common ancestral native from the Gondwana supercontinent.

Inspired by tokamaks, Brazilians researchers create via computer simulation an alternative for better control, in accelerators, of the particles' chaotic trajectories.

By testing an agrochemical designed to increase resistance on the mulberry plants used to feed silkworms, a research verified a rise in caterpillars' mortality and reduction in the size of cocoons. Intensive use of pesticides in monoculture systems may be the cause of silkworm crop losses in Brazil.

Professor Jean-Pierre Changeux, has been selected as the winner of the ALBERT EINSTEIN World Award of Science and Professor Malik Mâaza, will be awarded with the JOSÉ VASCONCELOS World Award of Education. The World Cultural Council's (WCC) 35th Award Ceremony will take place on 8 November 2018 for the first time in Hong Kong at City University of Hong Kong (CityU). During this event, the WCC will also grant special acknowledgements to nine promising young research leaders from CityU.

p53, known as the guardian of the genome, is a protein that blocks cancer development and progression. But mutated p53 adopts new roles and conformations that are catastrophic for the cell. A new study reports on innovative technique that traps p53 short-lived conformers.
