Last year, more than fifty years after initial theoretical proposals, researchers in Pisa, Stuttgart and Innsbruck independently succeeded for the first time in creating so-called supersolids using ultracold quantum gases of highly magnetic lanthanide atoms. This state of matter is, in a sense, solid and liquid at the same time. "Due to quantum effects, a very cold gas of atoms can spontaneously develop both a crystalline order of a solid crystal and particle flow like a superfluid quantum liquid, i.e.
Mothers and fathers of children diagnosed with cancer are affected financially in different ways. While mothers' incomes fall in the short term and then rise, the adverse financial repercussions on fathers occur later. Researchers at Uppsala University have investigated the socioeconomic impact on parents of having a child diagnosed with cancer. The study is published in the International Journal of Cancer.
High-performance, eco-friendly, safe and at the same time cost-effective: the zinc-air battery is an attractive energy storage technology of the future. Until now, the conventional zinc-air battery has struggled with a high chemical instability, parasitic reactions which rooted in the usage of alkaline electrolytes lead to electrochemical irreversibility. Based on an innovative, non-alkaline, aqueous electrolyte, an international research team led by scientist Dr.
PORTLAND, Ore. - Researchers at Oregon State University have found that a few organisms in the gut microbiome play a key role in type 2 diabetes, opening the door to possible probiotic treatments for a serious metabolic disease affecting roughly one in 10 Americans.
To make kefir, it takes a team. A team of microbes.
EUGENE, Ore. -- Jan. 4, 2021 -- Phosphorous, calcium and charcoal in spotty patches of fertile soil in the Amazon rainforest suggest that natural processes such as fires and river flooding, not the ingenuity of indigenous populations, created rare sites suitable for agriculture, according to new research.
What The Study Did: Denmark was one of the first countries to enforce lockdown to reduce the spread of COVID-19 and subsequent gradual reopening, whereas Sweden has had few restrictions, largely limited to public recommendations. Researchers assessed public mobility and social media attention associated with COVID-19 spread and societal interventions from February to June in Denmark and Sweden.

What The Study Did: Researchers used health insurance data from Taiwan to investigate the risk of substance use disorder among patients with autism spectrum disorder and its associations with risk of death.

Mollusks build shells to protect their soft tissues from predators. Nacre, also known as the mother of pearl, has an intricate, highly regular structure that makes it an incredibly strong material. Depending on the species, nacres can reach tens of centimeters in length. No matter the size, each nacre is built from materials deposited by a multitude of single cells at multiple different locations at the same time. How exactly this highly periodic and uniform structure emerges from the initial disorder was unknown until now.
Drones, robots and autonomous systems can transform the natural world in and around cities for people and wildlife.
International research, involving over 170 experts and led by the University of Leeds, assessed the opportunities and challenges that this cutting-edge technology could have for urban nature and green spaces.
The researchers highlighted opportunities to improve how we monitor nature, such as identifying emerging pests and ensuring plants are cared for, and helping people engage with and appreciate the natural world around them.
Whether in beta-blockers to treat high blood pressure or in natural products: So-called vicinal aminoalcohols are high-quality organic compounds that are found in many everyday products. However, their production is difficult. For a long time, chemists are trying to develop efficient methods of synthesizing them. In their recent study published in the journal Nature Catalysis, scientists led by Prof. Dr. Frank Glorius of Münster University have found a solution for the production of a special variant of aminoalcohols.
What The Viewpoint Says: The rapid spread of scientific misinformation on social media platforms throughout the COVID-19 pandemic is discussed in this Viewpoint, which also proposes strategies to counteract its adverse effects including surveillance of digital data and partnering with trusted messengers to engage the public and advance scientifically sound public health measures.

ITHACA, N.Y. - From an observatory high above Chile's Atacama Desert, astronomers have taken a new look at the oldest light in the universe.
Their observations, plus a bit of cosmic geometry, suggest that the universe is 13.77 billion years old - give or take 40 million years. A Cornell University researcher co-authored one of two papers about the findings, which add a fresh twist to an ongoing debate in the astrophysics community.
All prediabetes is not the same: in people in the preliminary stages of type 2 diabetes, there are six clearly distinguishable subtypes, which differ in the development of the disease, diabetes risk, and the development of secondary diseases. This is shown in a study by the Institute for Diabetes Research and Metabolic Diseases (IDM) of Helmholtz Zentrum München at the University of Tübingen, Tübingen University Hospital and the German Center for Diabetes Research (DZD). The results have now been published in Nature Medicine.
The coronavirus pandemic is creating a large spike in significant psychological distress among Americans, with the first month of the pandemic causing as much distress in the same number of individuals that experienced it during the whole previous year, according to a new RAND Corporation study.
