| Blueprints for how human kidneys form their filtering units Posted: 23 Aug 2021 09:58 AM PDT A team of scientists has conducted a comprehensive analysis reconstructing how kidneys form their filtering units, known as nephrons. The team studied hundreds of human and mouse nephrons at various points along their typical developmental trajectories, comparing important processes that have been conserved during the nearly 200 million years of evolution since humans and mice diverged from their common mammalian ancestor. The study details the similar genetic machinery that underpins nephron formation in humans and mice, enabling other groups of scientists to follow the logic of these developmental programs to make new types of kidney cells. |
| Phosphorescent material inspired by ‘glow in the dark’ wood Posted: 23 Aug 2021 09:58 AM PDT Scientists have harnessed the natural ability of wood to faintly glow to develop a new sustainable phosphorescent material that could potentially be used in a wide number of applications, from medical imaging and optical sensing to 'glow in the dark' dyes and paints. |
| Machine learning links material composition and performance in catalysts Posted: 23 Aug 2021 09:57 AM PDT In a finding that could help pave the way toward cleaner fuels and a more sustainable chemical industry, researchers have used machine learning to predict how the compositions of metal alloys and metal oxides affect their electronic structures. |
| High-rate magnesium rechargeable batteries move one step closer to realization Posted: 23 Aug 2021 09:57 AM PDT Magnesium rechargeable batteries show immense promise for a greener future because of their energy density, safety, and cost. But the lack of high-performance cathode materials has impeded their development. Now, a research team has developed liquid-sulfur/sulfide composite cathodes that enable high-rate magnesium batteries. |
| Smallest biosupercapacitor provides energy for biomedical applications Posted: 23 Aug 2021 09:57 AM PDT The miniaturization of microelectronic sensor technology, microelectronic robots or intravascular implants is progressing rapidly. However, it also poses major challenges for research. One of the biggest is the development of tiny but efficient energy storage devices that enable the operation of autonomously working microsystems -- in more and more smaller areas of the human body for example. In addition, these energy storage devices must be bio-compatible if they are to be used in the body at all. Now there is a prototype that combines these essential properties. |
| New air routes are vital for organ transplants Posted: 23 Aug 2021 09:57 AM PDT Research suggests that introducing new airline routes reduces the discard rate of donated kidneys and increases the number of kidneys sent to transplant centers across the U.S. |
| Lightweight composite material inspects itself: Changes in color indicate deformations Posted: 23 Aug 2021 09:57 AM PDT Researchers have developed a new type of laminate that changes color as soon as the material is deformed. This way, the materials researchers can kill two birds with one stone: a lightweight composite material that inspects itself. |
| Benefits outweigh risks for autonomous vehicles - if they are regulated Posted: 23 Aug 2021 09:56 AM PDT Experts have assessed the risks and potential benefits associated with deploying autonomous vehicles (AVs) on U.S. roads and predicts that the benefits will substantially outweigh potential harms -- but only if the AVs are well regulated. |
| Scientists distill cow’s milk into nano-capsules for drug delivery Posted: 23 Aug 2021 06:42 AM PDT Scientists have developed a novel way to isolate exosomes from cow's milk. Exosomes are nano-sized biological capsules that cells produce to protect and courier delicate molecules throughout the body. Harvesting them to achieve clinical-grade levels of purity, however, is a complex process. |
| Synthetic tissue model with blood vessels Posted: 23 Aug 2021 05:56 AM PDT Researchers investigate which material properties support vessel formation. |
| Accessing high-spins in an artificial atom Posted: 19 Aug 2021 07:27 AM PDT Researchers have devised a method for measuring the high-spin state of up to four electrons confined on a tiny gallium arsenide quantum dot. This research may lead to quantum computers that can process information by manipulating both electron charge and spin. |
