Nanocontainers Introduced Into the Nucleus of Living Cells

fahrbot-bot shares a report from Phys.Org: An interdisciplinary team from the University of Basel in Switzerland has succeeded in creating a direct path for artificial nanocontainers to enter into the nucleus of living cells. To this end, they produced biocompatible polymer vesicles that can pass through the pores that decorate the membrane of the cell nucleus. In this way, it might be possible to transport drugs directly into the cell's control center. In order to combat diseases, different therapies strive to intervene in pathological processes that occur in the cell nucleus. Chemotherapies, for example, target biochemical reactions that are involved in the proliferation of cancer cells, while the objective of gene therapies is to insert a desired gene into the nucleus. Therefore, a challenge in the field of nanomedicine is to develop a reliable method of introducing active substances specifically into the cell nucleus. Researchers at the University of Basel have now developed tiny nanocontainers that do just that in living cells. The findings have been published in the journal PNAS.

Dark Mode vs. Light Mode: Which Is Better?

Recently a well-respected UI consulting firm (the Nielsen Norman Group) published their analysis of academic studies on the question of whether Dark Mode or Light Mode was better for reading? Cosima Piepenbrock and her colleagues at the Institut für Experimentelle Psychologie in Düsseldorf, Germany studied two groups of adults with normal (or corrected-to-normal) vision: young adults (18 to 33 years old) and older adults (60 to 85 years old). None of the participants suffered from any eye diseases (e.g., cataract)... Their results showed that light mode won across all dimensions : irrespective of age, the positive contrast polarity was better for both visual-acuity tasks and for proofreading tasks... Another study, published in the journal Human Factors by the same research group, looked at how text size interacts with contrast polarity in a proofreading task. It found that the positive-polarity advantage increased linearly as the font size was decreased: namely, the smaller the fon...

Signal Is Finally Bringing Its Secure Messaging To the Masses

An anonymous reader quotes a report from Wired: [Cryptographer and coder known as Moxie Marlinspike] has always talked about making encrypted communications easy enough for anyone to use. The difference, today, is that Signal is finally reaching that mass audience it was always been intended for -- not just the privacy diehards, activists, and cybersecurity nerds that formed its core user base for years -- thanks in part to a concerted effort to make the app more accessible and appealing to the mainstream. That new phase in Signal's evolution began two years ago this month. That's when WhatsApp cofounder Brian Acton, a few months removed from leaving the app he built amid post-acquisition clashes with Facebook management, injected $50 million into Marlinspike's end-to-end encrypted messaging project. Acton also joined the newly created Signal Foundation as executive chairman. The pairing up made sense; WhatsApp had used Signal's open source protocol to encrypt all What...
