A study published in Nature discusses the newly discovered species, Yuezhuornis yangyuanensis, which lived during the Late Jurassic period (150–148 million years ago). The research suggests that the evolution of the avian body plan was not a straightforward progression toward improved flight capabilities, but a complex process involving the exploration of different ecological niches, including some that did not require flight.
Scientists have developed a material that can grow and coordinate its own movement until the entire structure pulses in unison, paving the way for versatile robots that behave more like living systems.
Publishing their findings on Oct. 14 in Nature, engineers from the University of Birmingham working with the Universities of Amsterdam, Lyon, Delft, Leiden and Cambridge reveal that they have created a mechatronic metamaterial that behaves as a ‘time crystal.'Scientists have identified and activated a small group of neurons responsible for the initiation of learned movements. The study used cutting-edge techniques to not only “read” brain activity down to the level of individual cells, but “write” patterns that allowed researchers to control movement.
Scientists at the University of Bath (UK) have produced a new azulene-based fluorescent probe that is five times brighter than the original molecule. Their research has uncovered the tiny molecular changes needed to transform both the colour and brightness of the probes, paving the way for more powerful imaging tools for detecting diseases such as Alzheimer's, Parkinson’s and cancer.
Collagen plays a critical role in keeping heart valves strong, but the heart is surrounded by enzymes designed to break down collagen. So how can heart valves function efficiently decade after decade? A new study shows that the biomechanical tension applied to these valves every time your heart beats plays a key role in protecting the collagen from breaking down.
A team from IRB Barcelona, in collaboration with the Sant Joan de Déu Research Institute and the Pediatric Cancer Center Barcelona at Sant Joan de Déu Hospital, has described a mechanism by which a cancer-related protein can activate regions of DNA that normally remain silenced.
Using the Drosophila fruit fly, the researchers demonstrated that this activation depends on collaboration with another protein, enabling the study of a mechanism that is difficult to isolate in human cells.
The study, published in G3: Genes|Genomes|Genetics, may help explain previous observations in prostate cancer and B-cell acute lymphoblastic leukemia.
