AI foundation model for eye care to supercharge global efforts to prevent blindness      (via sciencedaily.com) 

Researchers have developed an artificial intelligence (AI) system that has the potential to not only identify sight-threatening eye diseases but also predict general health, including heart attacks, stroke, and Parkinson's disease.

Nature's great survivors: Flowering plants survived the mass extinction that killed the dinosaurs      (via sciencedaily.com)     Original source 

A new study by researchers from the University of Bath (UK) and Universidad Nacional Autónoma de México (Mexico) shows that flowering plants escaped relatively unscathed from the mass extinction that killed the dinosaurs 66 million years ago. Whilst they suffered some species loss, the devastating event helped flowering plants become the dominant type of plant today.

Unlocking the genetic code of peppers: New study reveals insights into domestication and diversity      (via sciencedaily.com)     Original source 

Peppers are a versatile, flavorful, and widely popular crop, used not only as a healthy food source but also for their medicinal properties. Scientists have now sequenced the genomes of key cultivated and wild pepper species, offering unprecedented insights into pepper evolution, domestication, and genetic diversity.

You say tomato, these scientists say evolutionary mystery      (via sciencedaily.com)     Original source 

Biologists have found evidence for evolutionary 'syndromes'-- sets of traits that occur together -- that help to explain how tomatoes first evolved their distinctive blend of color, sweetness, acidity and aroma. The research not only shines a light on how fruits evolve in the wild, but will also be valuable to crop-improvement efforts aimed at breeding more nutritious and appealing varieties of fruits.

Not too big: Machine learning tames huge data sets      (via sciencedaily.com) 

A machine-learning algorithm demonstrated the capability to process data that exceeds a computer's available memory by identifying a massive data set's key features and dividing them into manageable batches that don't choke computer hardware. The algorithm set a world record for factorizing huge data sets during a test run on the world's fifth-fastest supercomputer. Equally efficient on laptops and supercomputers, the highly scalable algorithm solves hardware bottlenecks that prevent processing information from data-rich applications in cancer research, satellite imagery, social media networks, national security science and earthquake research, to name just a few.

AI can help write a message to a friend -- but don't do it      (via sciencedaily.com) 

Using artificial intelligence applications to help craft a message to a friend is not a good idea -- at least if your friend finds out about the use of AI, a new study suggests.

Online AI-based test for Parkinson's disease severity shows promising results      (via sciencedaily.com) 

A new artificial intelligence tool can help people with Parkinson's disease remotely assess the severity of their symptoms within minutes. While expert neurologists performed slightly better than the AI model, the AI model outperformed the primary care physicians with UPDRS certification.

How does the social behavior of wheat plants influence grain production?      (via sciencedaily.com)     Original source 

Researchers have investigated how the behavior of an individual wheat plant under limiting light conditions influences the performance of the whole community. They assessed morphological and biomass phenotypes of single plants grown in mixtures under sunlight and a simulated canopy shade, and the relevance of these phenotypes for the monoculture community in the field.

Human shoulders and elbows first evolved as brakes for climbing apes      (via sciencedaily.com)     Original source 

Researchers report that the flexible shoulders and elbows that allow us to throw a football or reach a high shelf may have evolved as a natural braking system that let our primate ancestors get out of trees without dying. The researchers used sports-analysis software to compare the climbing movements of chimpanzees and small monkeys called mangabeys. While the animals climb up trees similarly, the researchers found that the shallow, rounded shoulder joints and shortened elbow bones that chimps have -- similar to humans -- allow them to fully extend their arms above their heads when climbing down, holding onto branches like a person going down a ladder to support their greater weight. When early humans left forests for the grassy savanna, these versatile appendages would have been essential for gathering food and using tools for hunting and defense. The findings are among the first to identify the significance of 'downclimbing' in the evolution of apes and early humans.

Most species are rare, but not very rare      (via sciencedaily.com)     Original source 

More than 100 years of observations in nature have revealed a universal pattern of species abundances: Most species are rare but not very rare, and only a few species are very common. These so-called global species abundance distributions have become fully unveiled for some well-monitored species groups, such as birds. For other species groups, such as insects, however, the veil remains partially unlifted. A new study demonstrates how important biodiversity monitoring is for detecting species abundances on planet Earth and for understanding how they change.
