An estimated 2.3 million cancer cases worldwide in 2024, about one in eight, were attributable to infections, according to a study published in The Lancet Oncology. "This recent Lancet data is a profound reminder that a significant portion of our global cancer burden is fundamentally preventable," said David Greenberg, MD, of Hackensack Meridian Jersey Shore University Medical Center, in a news release. "We have historically siloed infectious diseases and oncology, but they are deeply intertwined. By shifting our focus toward aggressive infection control, we can literally vaccinate and treat our way out of millions of future cancer diagnoses." From a report: The study found that an estimated 2.3 million new cancer cases were attributable to infections globally in 2024, equivalent to 12% of all cancer cases. Of these, the largest number (760,000 cases, or 4%) were caused by H. pylori, followed by HPV (750,000 cases, or 4%), HBV (360,000 cases, or 2%), EBV (260,000 cases, or 1%) and HCV (160,000 cases). More than three quarters of infection-attributable cancers occurred in low- and middle-income countries. Eastern Asian had the largest burden, with 990,000 cases (42% of the global total). Rates were also higher than the global average in sub-Saharan Africa, Central and Eastern Europe and Southeast Asia.

alternative_right shares a report from Phys.org: Nanoparticles could someday provide a new way to help soldiers fight back against deadly nerve agents on the front lines. In a new study, Northwestern University scientists developed a nanoparticle-based compound that, when mixed into clothing dyes, could limit the impact of chemicals commonly found in pesticides, insecticides and nerve agents. Manufacturers could potentially add the nanoparticles to clothing used by those most at risk, such as farmers' masks and gloves or soldiers' uniforms and tactical gear. Or, if someone is exposed to a potentially deadly chemical, they could spray their clothing with water mixed with the compound to deactivate the chemical before its damaging effects take hold. The study has been published in the journal ACS Nano.

Also reporting from Euronews where I got the link to the article Me: This demonstrates a systematic issue and reinforces the need to talk with a doctor about treatment plans if you can and not just go with the flow when overwhelmed or in pain.

This sort of research is both exciting and terrifying:

The two models in question were told to generate complete genomes for a viable bacteriophage—a type of virus able to infect and replicate itself inside bacteria, destroying them from the inside.

Using an existing bacteriophage as an example—ΦX174 (pronounced “fie-ex-1-7-4”), known for its ability to infect and destroy E. coli bacteria—the models generated about 700,000 potential designs, of which the researchers picked 285 that looked most promising.

The researchers then synthesised new DNA molecules using those designs and inserted them into E. coli bacteria, before waiting to see if viable bacteriophages would emerge.

Shortly afterwards, 16 of the Petri dishes in which the bacteria were growing began to show clear spots, as the viruses began to attack and replicate themselves inside the E. coli, demonstrating their viability.

Some of those viable viruses proved more effective at attacking E. coli than the original ΦX174 bacteriophage.

That’s a positive use of a synthetic virus. We can all imagine the negative uses.
