Human contact plays big role in spread of some hospital infections, but not others

An observational study conducted in a French hospital showed that human contact was responsible for 90 percent of the spread of one species of antibiotic-resistant bacteria to new patients, but less than 60 percent of the spread of a different species. Audrey Duval of the Versailles Saint Quentin University and Institut Pasteur in Paris, France, and colleagues present these findings in PLOS Computational Biology.

Scientists engineer unique 'glowing' protein

Biophysicists from the Moscow Institute of Physics and Technology have joined forces with colleagues from France and Germany to create a new fluorescent protein. Besides glowing when irradiated with ultraviolet and blue light, it is exceedingly small and stable under high temperatures. The authors of the paper, published in the journal Photochemical & Photobiological Sciences, believe the protein holds prospects for fluorescence microscopy. This technique is used in research on cancer, infectious diseases, and organ development, among other things.

Entrectinib gets edge over crizotinib against ROS1+ lung cancer

Crizotinib and entrectinib are both active against ROS1+ non-small cell lung cancer. But which is best? The answer seems easy: Just compare the drugs' clinical trial results. However, not all trials are created equal, and these differences in trial designs can lead to irrelevant comparisons—like comparing athletes' running times without noting that one ran a kilometer while the other ran a mile. Now results from an innovative, "virtual" clinical trial presented at the American Society for Clinical Oncology (ASCO) Annual Meeting 2019 attempt to place crizotinib and entrectinib on an equal playing field. In this analysis, patients taking entrectinib were able to stay on treatment longer and had about almost 6 months longer progression-free survival than patients treated with crizotinib.

Researchers try to recreate human-like thinking in machines

Researchers at Oxford University have recently tried to recreate human thinking patterns in machines, using a language guided imagination (LGI) network. Their method, outlined in a paper pre-published on arXiv, could inform the development of artificial intelligence that is capable of human-like thinking, which entails a goal-directed flow of mental ideas guided by language.
