AI transformation of medicine: Why doctors are not prepared      (via sciencedaily.com) 

The success of artificial intelligence technologies depends largely on how physicians interpret and act upon a tool's risk predictions -- and that requires a unique set of skills that many are currently lacking, according to a new perspective article.

Deep learning for new protein design      (via sciencedaily.com) 

Deep learning methods have been used to augment existing energy-based physical models in 'do novo' or from-scratch computational protein design, resulting in a 10-fold increase in success rates verified in the lab for binding a designed protein with its target protein. The results will help scientists design better drugs against diseases like cancer and COVID-19.

Google and ChatGPT have mixed results in medical informatiom queries      (via sciencedaily.com) 

Computer scientists found that queries for medical information about dementia disease on ChatGPT provided more objective results than similar queries on Google, but both services have strengths and weaknesses. Google provided the most current information, but the query results are skewed by service and product providers seeking customers, the researchers found. ChatGPT, meanwhile, provides more objective information, but it can be outdated and lacks the sources of its information in its narrative responses.

That's funny -- but AI models don't get the joke      (via sciencedaily.com) 

Using hundreds of entries from the New Yorker magazine's Cartoon Caption Contest as a testbed, researchers challenged AI models and humans with three tasks: matching a joke to a cartoon; identifying a winning caption; and explaining why a winning caption is funny.

Why computer security advice is more confusing than it should be      (via sciencedaily.com) 

If you find the computer security guidelines you get at work confusing and not very useful, you're not alone. A new study highlights a key problem with how these guidelines are created, and outlines simple steps that would improve them -- and probably make your computer safer.

Detecting threats beyond the limits of human, sensor sight      (via sciencedaily.com)     Original source 

A new patented software system can find the curves of motion in streaming video and images from satellites, drones and far-range security cameras and turn them into signals to find and track moving objects as small as one pixel. The developers say this system can enhance the performance of any remote sensing application.

Researcher turns one of the basic rules of construction upside down      (via sciencedaily.com)     Original source 

Structural engineers are familiar with seventeenth-century scientist Robert Hooke's theory that a hanging chain will mirror the shape of an upstanding rigid arch. However, new research now shows that this common-held belief is incorrect because, regardless of the similarities, the hanging chain and the arch are two incompatible mechanical systems.

GPT detectors can be biased against non-native English writers      (via sciencedaily.com)     Original source 

Researchers show that computer programs commonly used to determine if a text was written by artificial intelligence tend to falsely label articles written by non-native language speakers as AI-generated. The researchers caution against the use of such AI text detectors for their unreliability, which could have negative impacts on individuals including students and those applying for jobs.

Number cruncher calculates whether whales are acting weirdly      (via sciencedaily.com)     Original source 

We humans can be a scary acquaintance for whales in the wild. This includes marine biologists tagging them with measuring devices to understand them better. These experiences can make whales behave erratically for a while. Such behaviour can affect research quality and highlights an animal ethics dilemma. Now, researchers have figured out how to solve the problems with math.
