While most believe artificial intelligence (AI) is changing science, researchers at the University of Notre Dame are exploring the reverse. In an article published in Chemical Reviews, AI and chemistry experts alike discussed how the intricacies of organic chemistry are changing the way researchers design AI technology, leading the way for a new generation of development. 

An IIT Gandhinagar-Indian Council of Agricultural Research-DRMR study has characterised the self-rejection genes in India’s commercial mustard varieties, toria and yellow sarson. Combining molecular genetics with Artificial Intelligence-based protein structure prediction, the team mapped the four genes that allow some mustard flowers to turn away their own pollen. The study sheds light on a natural mechanism breeders can harness to produce the high-yielding hybrids the country needs to cut its heavy reliance on imported edible oil. 

Scientists at HHMI's Janelia Research Campus and collaborators have completed a wiring diagram of the central nervous system of an adult male fruit fly, the culmination of nearly two decades of groundbreaking research.

With the advancement of long-term crewed deep-space exploration missions, the effects of the microgravity environment on astronauts' brain function have become an important topic in aerospace medicine. The disappearance of the hydrostatic pressure gradient during spaceflight induces cephalad fluid shifts, which can alter cerebral blood flow (CBF) and are closely associated with visual impairment, spatial disorientation, and cognitive decline. However, existing studies have predominantly focused on the steady-state phase during the middle and late stages of microgravity exposure, with insufficient understanding of the characteristics of CBF fluctuations during the early phase of postural transitions. Moreover, as an indicator of terminal perfusion in the cerebral microcirculation, the coupling relationship between CBF and the upstream hemodynamics of the internal carotid and vertebral arteries has not been systematically investigated. In addition, magnetic resonance imaging (MRI) cannot be applied in real time during spaceflight due to its bulky equipment, whereas ultrasound offers the advantages of portability, real-time capability, and radiation-free operation. Therefore, elucidating the association between early macrovascular hemodynamic changes under simulated microgravity and regional CBF alterations, and evaluating the feasibility of using ultrasound parameters as portable predictors of CBF, holds significant scientific importance and application value.
