SARS-CoV-2 has evolved to acquire mutations on the spike protein the part of the virus that protrudes from its surface and latches onto cells to infect them that enhance the coronavirus ability to bind to human cells or evade antibodies. A new study from the Centers for Genomics and Systems Biology at New York University and NYU Abu Dhabi uses computational modeling to assess the biological significance of spike protein mutations, uncovering versions of the virus that bind more tightly or resist antibodies and offering a promising public health surveillance tool. ....

Researchers have found the elusive genetic element controlling the elongated grains and glumes of a wheat variety identified by the renowned botanist Carl Linnaeus more than 250 years ago.
The findings relating to Polish wheat, Triticum polonicum, could translate into genetic improvements and productivity in the field.
Wheat, in bread, pasta, and other forms, is a vital energy and protein source for humans. Each individual grain is nestled within the glumes and other leaf-like organs called lemma and palea which affect the grain s final size, shape, and weight. ....

On 27 April, participants from more than 100 countries gathered to discuss key lessons from the COVID-19 pandemic. As part of an enterprise implemented by Portugal during its presidency of the Council of the EU, EMBL and Portugal brought international experts together for a virtual conference. A wide range of topics were covered, including immunology, infectious diseases, and the molecular biology of viruses. The conference provided a valuable opportunity to ensure that important lessons are not lost in the rush towards a world where life is no longer so dominated by COVID-19. ....
