Self-improving AI method increases 3D-printing efficiency      (via sciencedaily.com)     Original source 

An artificial intelligence algorithm can allow researchers to more efficiently use 3D printing to manufacture intricate structures. The development could allow for more seamless use of 3D printing for complex designs in everything from artificial organs to flexible electronics and wearable biosensors. As part of the study, the algorithm learned to identify, and then print, the best versions of kidney and prostate organ models, printing out 60 continually improving versions.

Peering into the mind of artificial intelligence to make better antibiotics      (via sciencedaily.com)     Original source 

Artificial intelligence (AI) has exploded in popularity as of late. But just like a human, it's hard to read an AI model's mind. Explainable AI (XAI) could help us do just that by providing justification for a model's decisions. And now, researchers are using XAI to scrutinize predictive AI models more closely, which could help make better antibiotics.

Why do researchers often prefer safe over risky projects? Explaining risk aversion in science      (via sciencedaily.com)     Original source 

A mathematical framework that builds on the economic theory of hidden-action models provides insight into how the unobservable nature of effort and risk shapes investigators' research strategies and the incentive structures within which they work, according to a new study.

Leading AI models struggle to identify genetic conditions from patient-written descriptions      (via sciencedaily.com)     Original source 

Researchers discover that while artificial intelligence (AI) tools can make accurate diagnoses from textbook-like descriptions of genetic diseases, the tools are significantly less accurate when analyzing summaries written by patients about their own health. These findings demonstrate the need to improve these AI tools before they can be applied in health care settings to help make diagnoses and answer patient questions.

AI poses no existential threat to humanity, new study finds      (via sciencedaily.com)     Original source 

Large Language Models (LLMs) are entirely controllable through human prompts and lack 'emergent abilities'; that is, the means to form their own insights or conclusions. Increasing model size does not lead LLMs to gain emergent reasoning abilities, meaning they will not develop hazardous abilities and therefore do not pose an existential threat. A new study sheds light on the (until now unexplained) capabilities and shortcomings of LLMs, including the need for carefully engineered prompts to exhibit good performance.

Researchers outline promises, challenges of understanding AI for biological discovery      (via sciencedaily.com)     Original source 

Machine learning is a powerful tool in computational biology, enabling the analysis of a wide range of biomedical data such as genomic sequences and biological imaging. But when researchers use machine learning in computational biology, understanding model behavior remains crucial for uncovering the underlying biological mechanisms in health and disease. Researchers now propose guidelines that outline pitfalls and opportunities for using interpretable machine learning methods to tackle computational biology problems.

Early mammals lived longer      (via sciencedaily.com)     Original source 

What distinguishes the growth and development patterns of early mammals of the Jurassic period? Paleontologists have been able to gauge the lifespan and growth rates of these ancient animals, and even when they reached maturity, by studying growth rings in fossilized tooth roots.

Smallest arm bone in human fossil record sheds light on the dawn of Homo floresiensis      (via sciencedaily.com)     Original source 

A new study reports the discovery of extremely rare early human fossils from the Indonesian island of Flores, including an astonishingly small adult limb bone. Dated to about 700,000 years old, the new findings shed light on the evolution of Homo floresiensis, the so-called 'Hobbits' of Flores whose remains were uncovered in 2003 at Liang Bua cave in the island's west.
