› Vitamin D deficiency for the first time visible after cremation
The cremation process destroys a lot of information that can usually be obtained from the human skeleton. Especially diseases are difficult to observe. Researchers have now found a way to reveal some of the information. For the first time, they have succeeded in detecting vitamin D deficiency in cremated human remains. |

› Infant planet discovered
One of the youngest planets ever found around a distant infant star has been discovered by an international team of scientists. |

› Controlling light with a material three atoms thick
Thin structures made of black phosphorus can tune the properties of light, with implications for science and technology. |

› A diet of essential amino acids could keep dementia at bay
Protein intake is known to be vital for maintaining brain function in older individuals. Now, using a mouse model of Alzheimer's disease, researchers have shown that the intake of a specific set of amino acids can inhibit the death of brain cells, protect the connections between them, and reduce inflammation, preserving brain function. Their research suggests that this amino acid combination called Amino LP7 can hinder the development of dementia, including Alzheimer's disease. |

› Stronger than spider silk: Bagworm silk enables strong conducting fibers
Researchers have harnessed the strength of bagworm silk to produce a strong conductive fiber. To obtain this novel fiber, the research team combined bagworm silk with polyaniline as a conducting polymer. The composite fibers act as an optical waveguide and are suitable for use in textile transistors. This production of a bagworm silk/polyaniline composite will enable the use of biocompatible conducting fibers for applications ranging from microelectronics to biomedical engineering. |

› Traces of an ancient road in a lake
Eight hundred years of settlement history with land reforms, epidemics and repeated wars are preserved in the sediments of Lake Czechowskie in Poland. The key role was played by the so-called Margrave's Road, the 'Via Marchionis', between the Prussian heartland and the Teutonic Order's castle Marienburg (today Malbork in Poland). The road remained significant for centuries. |

› Need for larger space telescope inspires lightweight flexible holographic lens
Inspired by a concept for discovering exoplanets with a giant space telescope, a team of researchers is developing holographic lenses that render visible and infrared starlight into either a focused image or a spectrum. |

› Historical analysis finds no precedent for the rate of coal and gas power decline needed to limit climate change to 1.5°C
Limiting climate change to the 1.5°C target set by the Paris Climate Agreement will likely require coal and gas power use to decline at rates that are unprecedented for any large country, finds an analysis of decadal episodes of fossil fuel decline in 105 countries between 1960 and 2018. Furthermore, the findings suggest that the most rapid historical cases of fossil fuel decline occurred when oil was replaced by coal, gas, or nuclear power in response to energy security threats of the 1970s and the 1980s. |

› Electrical control over designer quantum materials
In the past few years, suitably engineered stacks of two-dimensional materials have emerged as a powerful platform for studying quantum correlations between electronic states. Physicists now demonstrate how key properties of such systems can be conveniently tuned by changing an applied electrical field. |

› VR experiment with rats offers new insights about how neurons enable learning
A new study provides deep insights into how the brain's hippocampus works, involving networks of millions of neurons. That knowledge could be an important step toward the development of treatments for neurological disorders such as Alzheimer's disease, schizophrenia and epilepsy, all of which are related to dysfunction in the hippocampus. |

› Discovery of new tiny fish, lizard species
Two tiny new species that inhabited part of what is now the American south some 100 million years ago have been discovered by paleontologists. |
