Structure-based prediction of T cell receptor recognition of unseen epitopes using TCRen
Abstract T cell receptor (TCR) recognition of foreign peptides presented by major histocompatibility complex protein is a major event in triggering the adaptive immune response to pathogens or cancer. The prediction of TCR–peptide interactions has great importance for therapy of cancer as well as infectious and autoimmune diseases but remains a major challenge, particularly for…

A decomposition of light’s spin angular momentum density
Abstract Light carries intrinsic spin angular momentum (SAM) when the electric or magnetic field vector rotates over time. A familiar vector equation calculates the direction of light’s SAM density using the right-hand rule with reference to the electric and magnetic polarisation ellipses. Using Maxwell’s equations, this vector equation can be decomposed into a sum of…

Canada just hiked PhD and postdoc pay — here’s how to get your country to do it, too
Graduate students and postdoctoral scholars often struggle to make ends meet, despite playing a crucial part in driving research and innovation. The cost-of-living crisis, which took root in many countries in late 2021, has worsened the situation. Respondents to a November 2022 Nature survey of early-career academics reported sometimes having to get groceries from food…

How PhD students and other academics are fighting the mental-health crisis in science
On the first day of her class, Annika Martin asks the assembled researchers at the University of Zurich in Switzerland to roll out their yoga mats and stand with their feet spread wide apart. They place their hands on their hips before swinging their torsos down towards the mat and back up again. The pose,…

Iran elects heart surgeon as president: scientists are hopeful
Iran has elected a former heart surgeon as its next president. Scientists expect Masoud Pezeshkian, who ran the nation’s health ministry in an earlier administration, to revive universities and reconnect the country’s isolated scientists with their international counterparts. His term could also usher in improvements to human rights, investment in science, greater academic freedom and…

How conspiracies took root in our culture
Think to New Worlds: The Cultural History of Charles Fort and His Followers Joshua Blu Buhs Univ. Chicago Press (2024) In March 2024, a mammoth review by the US Department of Defense concluded that there was “no evidence” that the US government had encountered alien life. Yet, that pronouncement is unlikely to have changed many…
