To raise new questions, new possibilities, to regard old problems from a new angle, requires creative imagination and marks real advance in science.

Old Newtonian physics claimed that things have an objective reality separate from our perception of them. Quantum physics, and particularly Heisenberg's Uncertainty Principle, reveal that, as our perception of an object changes, the object itself literally changes.

The top row depicts immature human heart muscle cells generated from stem cells. Their shape and fibre organisation is irregular. Upon Rbfox1 expression, the cells, as seen in the lower row, are more organised, closer to the shape and organisation of mature muscle cells in an adult heart.

Circulation. 2023;148(16):1263-1266. doi: 10.1161/circulationaha.122.061602)
Researchers identify RBFox1 as a key intrinsic regulator of heart muscle cell maturation, overcoming a major limitation in cardiac regenerative therapy and disease modelling and demonstrating for the first time that RNA splicing control can significantly impact this process.

Researchers at NASA’s Langley Research Center in Hampton, Virginia recently flew multiple drones beyond visual line of sight with no visual observer. The drones successfully flew around obstacles and each other during takeoff, along a planned route, and upon landing, all autonomously without a pilot controlling the flight. This test marks an important step towards advancing self-flying capabilities for air taxis.
“Flying the vehicles beyond visual line of sight, where neither the vehicle nor the airsp...
Composite image of the Galactic plane region and Potoroo, with the red layer showing the ASKAP total intensity image at 1368 MHz, and the green and blue layers representing WISE infrared images at 12 µm and 22 µm respectively. Known Galactic SNRs are indicated by red circles (Green, 2019, 2022), while known Galactic HII regions are marked by green circles (Anderson et al., 2014). The box highlights the section of deep interest. The inset is the ASKAP zoomed-in image showing Potoroo where a red cross marks the position of the X-ray source, while a red dashed line is Potoroo’s axis of symmetry, which corresponds to the tail length studied in this paper.

With more of us looking for alternatives to eating animals, new research has found a surprising environmentally friendly source of protein – algae.
The University of Exeter study has been published in The Journal of Nutrition and is the first of its kind to demonstrate that the ingestion of two of the most commercially available algal species are rich in protein which supports muscle remodeling in young healthy adults. Their findings suggest that algae may be an interesting and sustainable alternative to animal-derived protein with respect to maintaining and building muscle.
Researcher Ino Van Der Heijden from the University of Exeter said: “Our work has shown algae could become part of a secure and sustainable food future...
