Modified virtual reality tech can measure brain activity      (via sciencedaily.com) 

The research team at The University of Texas at Austin created a noninvasive electroencephalogram (EEG) sensor that they installed in a Meta VR headset that can be worn comfortably for long periods. The EEG measures the brain's electrical activity during the immersive VR interactions.

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.

Researchers discuss the ethical challenges of studying DNA from a 18th--19th century African American community      (via sciencedaily.com)     Original source 

A population genetics team recently identified the genetic relationship between over 40,000 23andMe users and a population of enslaved and free African Americans that lived in Catoctin Furnace, Maryland between 1776--1850. Over the course of this study, the researchers considered how best to inform descendants and other genetic relatives of their genetic connection to the site.

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 ChatGPT, meanwhile, provides more objective information, but it can be outdated and lacks the sources of its information in its narrative responses.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.

Reinforcement learning allows underwater robots to locate and track objects underwater      (via sciencedaily.com) 

A team has shown that reinforcement learning -i.e., a neural network that learns the best action to perform at each moment based on a series of rewards- allows autonomous vehicles and underwater robots to locate and carefully track marine objects and animals.

Family trees from the European Neolithic      (via sciencedaily.com)     Original source 

The Neolithic burial site of Gurgy 'les Noisats' in France revealed two unprecedentedly large family trees which allowed a Franco-German team to explore the social organization of the 6,700-year-old community. Based on multiple lines of evidence, the team describes a close kin group which practiced monogamy and female exogamy, and experienced generally stable times.

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.
