“Gene editing offers unique opportunities to make food production more sustainable and to further improve the quality, but also the safety, of food. With the help of these new molecular tools, more robust plants can be developed that deliver high yields for high-quality nutrition, even with less fertiliser,” says co-author Stephan Clemens, Professor of Plant Physiology at the University of Bayreuth and founding Dean of the new Faculty of Life Sciences: Food, Nutrition & Health on the Kulmbach campus.

For more sustainability on a global level, EU legislation should be changed to allow the use of gene editing in organic farming. This is what an international research team involving the Universities of Bayreuth and Göttingen demands in a paper published in the journal “Trends in Plant Science”.

In May 2020, the EU Commission presented its “Farm-to-Fork” strategy, which is part of the “European Green Deal”. The aim is to make European agriculture and its food system more sustainable. In particular, the proportion of organic farming in the EU’s total agricultural land is to be increased to 25 percent by 2030. However, if current EU legislation remains in place, this increase will by no means guarantee more sustainability, as the current study by scientists from Bayreuth, Göttingen, Düsseldorf, Heidelberg, Wageningen, Alnarp, and Berkeley shows.

Large swaths of U.S. military land are covered with munitions components, including the explosive chemical RDX. This molecule is toxic to people and can cause cancer. It also doesn’t naturally break down and can contaminate groundwater. Now researchers have genetically engineered a grass commonly used to fight soil erosion so that it can remove RDX from the soil, according to a new paper published May 3 in Nature Biotechnology.

A team, which includes researchers from the University of Washington, demonstrated that over the course of three years, a genetically engineered switchgrass could break down an explosive chemical in…

At Rehab, a nurse explained to me that my swallowing problem was caused by weak muscles in the esophageal sphincter. That information stimulated me to create my own therapy for the esophageal sphincter. I wrote out the transcript for the therapy, and a lady named Collette read it into a recorder. I listen to the recording several times a day. My swallowing problems resulted in a feeding being inserted up my nose. The therapy makes it possible for me to eat oatmeal, grits, eggs, pasta & beef, and corn flakes. After passing the swallowing test last Friday, the Speech Pathologist sent me to the Emergency Room, where they pulled the feeding tube from my nose.

Dysphagia refers to the difficulty in swallowing after a stroke. It is a problem that can be easily managed with proper medical care.

Quantum entanglement occurs when two separate entities become strongly linked in a way that cannot be explained by classical physics; it is a powerful resource in quantum communication protocols and advanced technologies that aim to exploit the enhanced capabilities of quantum systems. To date, entanglement has generally been limited to microscopic quantum units such as pairs or multiples of single ions, atoms, photons, and so on. Kotler et al. and Mercier de Lépinay et al. demonstrate the ability to extend quantum entanglement to massive macroscopic systems (see the Perspective by Lau and Clerk). Entanglement of two mechanical oscillators on such a large length and mass scale is expected to find widespread use in both applications and fundamental physics to probe the boundary between the classical and quantum worlds.

Quantum entanglement of mechanical systems emerges when distinct objects move with such a high degree of correlation that they can no longer be described separately. Although quantum mechanics presumably applies to objects of all sizes, directly observing entanglement becomes challenging as masses increase, requiring measurement and control with a vanishingly small error. Here, using pulsed electromechanics, we deterministically entangle two mechanical drumheads with masses of 70 picograms. Through nearly quantum-limited measurements of the position and momentum quadratures of both drums, we perform quantum state tomography and thereby directly observe entanglement. Such entangled macroscopic systems are poised to serve in fundamental tests of quantum mechanics, enable sensing beyond the standard quantum limit, and function as long-lived nodes of future quantum networks.

Humans are distinguished from other species by several aspects of cognition. While much comparative evolutionary neuroscience has focused on the neocortex, increasing recognition of the cerebellum’s role in cognition and motor processing has inspired considerable new research. Comparative molecular studies, however, generally continue to focus on the neocortex. We sought to characterize potential genetic regulatory traits distinguishing the human cerebellum by undertaking genome-wide epigenetic profiling of the lateral cerebellum, and compared this to the prefrontal cortex of humans, chimpanzees, and rhesus macaque monkeys. We found that humans showed greater differential CpG methylation–an epigenetic modification of DNA that can reflect past or present gene expression–in the cerebellum than the prefrontal cortex, highlighting the importance of this structure in human brain evolution. Humans also specifically show methylation differences at genes involved in neurodevelopment, neuroinflammation, synaptic plasticity, and lipid metabolism. These differences are relevant for understanding processes specific to humans, such as extensive plasticity, as well as pronounced and prevalent neurodegenerative conditions associated with aging.

Organic transistors that can simulate basic synaptic functions and act as biomimetic devices are advantageous for next generation bioelectronics. Here, the authors realize non-volatile organic electrochemical transistors with optimized performance required for associative learning circuits.
