End of life physician-patient communication

A study found that physician-patient communication training using the Four Habits Model can have a positive impact on the delivery of end-of-life care. The training increased professional satisfaction among physicians and enhanced their ability to express condolences, advance care planning discussions, and manage family emotions.

Biology enters 'The Matrix' through new computer language

Researchers have developed a computational language called Little b that can assemble complex models of proteins and their interactions with DNA. By incorporating principles of engineering, the program allows for modularity and abstraction, enabling scientists to build upon existing models and refine them in new ways.

Measuring the stress of forested areas

Researchers at the University of the Basque Country study plants' defence mechanisms to predict photo-oxidative stress. They discover antioxidants like vitamin E and carotenoids, which help protect plants from excessive light, and identify new cycles like the lutein epoxide cycle.

Parasitic worm infections increase susceptibility to AIDS viruses

A recent study published in PLoS Neglected Tropical Diseases found that parasitic worm infections can increase the risk of acquiring HIV/AIDS. The study showed that rhesus macaques with acute schistosomiasis were more susceptible to an HIV-like virus, with higher peak viral loads and memory cell concentrations.

No need for gene screens in breast cancer families

A recent study published in BMC Cancer reveals that a family history of breast cancer does not significantly increase the likelihood of developing the disease at an early age. The research suggests that applying strict screening criteria can help reduce unnecessary testing and alleviate psychological harm.

Cancer drug delivery research at Case Western Reserve University cuts time from days to hours

Researchers at Case Western Reserve University have developed a technique that can deliver cancer-fighting drugs to diseased areas within hours, reducing the current delivery time from two days. The system uses gold nanoparticle vectors to deliver photodynamic therapy (PDT) drugs through the bloodstream.
