Researchers at New York University have created artificial Hox genes—which plan and direct where cells go to develop tissues or organs—using new synthetic DNA technology and genomic engineering in stem cells. from Phys.org - latest science and technology news stories https://ift.tt/dNum9rA

Current AIs are very accurate but inflexible at image recognition. Exactly why this is remains a mystery. Researchers have developed a method called 'Raw Zero-Shot' to assess how neural networks handle elements unknown to them. The results have the potential to help researchers identify the common features that make neural networks 'non-robust,' and develop methods to make AIs more reliable. from Latest Science News -- ScienceDaily https://ift.tt/p8EHwU3

A gardener in Pasco County recently found a giant African land snail—or what Florida officials call "one of the most damaging snails in the world." from Phys.org - latest science and technology news stories https://ift.tt/KSkR0Ye

While there are many studies that discuss antibiotic resistance genes (ARG) in soil and water environments, there is currently very little research that focuses on ARG in aerial environments. In a recent review, researchers have analyzed current research trends regarding ARG in bioaerosols, including their sources, methods of detection, and implications for the future. from Latest Science News -- ScienceDaily https://ift.tt/Hra9zt8

Winemaking practices in coastal Italy during the Roman period involved using native grapes for making wine in jars waterproofed with imported tar pitch, according to a study published June 29, 2022 in PLOS ONE by Louise Chassouant of Avignon University and colleagues. from Phys.org - latest science and technology news stories https://ift.tt/wNm2lME

American Heart Association's checklist to measure cardiovascular health is updated, now called Life's Essential 8™, adding healthy sleep as essential for optimal cardiovascular health. Other health and lifestyle factors in the checklist, which were part of the previous, 7-item scoring tool, are nicotine exposure, physical activity, diet, weight, blood glucose, cholesterol and blood pressure. The new sleep metric suggests 7-9 hours of sleep daily for optimal cardiovascular health for adults, and more for children depending on age. from Latest Science News -- ScienceDaily https://ift.tt/5SDvGyf
