Nanomedicines - typically drugs hidden within nanoscopic fatty membranes ('liposomes') - have potential to transform chemotherapy treatments, improving drug delivery and reducing toxic side effects for thousands of cancer patients every year.

Now, world first research conducted by the University of South Australia has identified that the frequently used chemotherapy drug (5-FU or Fluorouracil) is 100 per cent more effective at targeting tumours (rather than surrounding tissues) when administered using an optimised liposomal formulation.

As COVID-19 upended societal norms when it swept through the United States in 2020, a second pandemic - or "infodemic" - was also on the rise. An analysis of Twitter users by researchers at the University of California, Davis, and University of Texas, Austin, suggests that Republican-identifying individuals who believe their local government has positive intentions are vulnerable to believing politically fueled COVID-19 misinformation.

Investigators at Cedars-Sinai have identified a potential new therapy for COVID-19: a biologic substance created by reengineered human skin cells.

Scientists found the substance stopped SARS-CoV-2, the virus that causes COVID-19, from reproducing itself and also protected infected cells when tested in human lung cells.

SARS-CoV-2 viruses can hide from recognition by the immune system. However, the antiviral immune receptor RIG-I can be stimulated, which improves protection against lethal SARS-CoV-2 infections. Researchers led by Prof. Dr. Gunther Hartmann from the Institute of Clinical Chemistry and Clinical Pharmacology at the University Hospital Bonn, in cooperation with other members of the cluster of excellence ImmunoSensation2 at the University of Bonn, have shown this in mice.

By combining CRISPR technology with a protein designed with artificial intelligence (AI), it is possible to awaken individual dormant genes by disabling the chemical “off switches” that silence them. Researchers from the University of Washington School of Medicine in Seattle describe this finding in the journal Cell Reports.

The national science academies of the G7 states publish a joint statement on Russia's attack on Ukraine.

The science academies have been accompanying the annual meetings of the G7 states for more than 15 years. In the run-up to each summit, they address scientific agenda-related issues that require multilateral action.

A new study has found that artificial intelligence (AI) apps helped protect small and medium-sized businesses against many of the risks that emerged during the COVID-19 pandemic - yet only a quarter of small firms currently use them.

The research, undertaken by Anglia Ruskin University (ARU) and published in the journal Information Systems Frontiers, surveyed 317 small and medium sized firms based in London.
