Researchers from 68 sites across the country, led by David E.
An international team of scientists from NUST MISIS (Russia), Linköping University (Sweden) and University of Bayreuth (Germany) found that, contrary to the usual physical and chemical laws, the structure of some materials does not condense at ultrahigh pressures. Actually, it forms a porous framework filled with gas molecules. This happened with samples of Os, Hf, and W put together with N in a diamond anvil at a pressure of one million atmospheres. The discovery is described in Angewandte Chemie.
Next on the list of concerns, though notably less frequently mentioned, are unhealthy or wrong diet as well as climate and environmental pollution - these were the most frequently mentioned concerns in February's survey. "The coronavirus pandemic dominates public perception", says BfR President Professor Dr. Dr. Andreas Hensel.

Popular wisdom holds that tall, fast-growing trees are best for biomass, but new research by two U.S. Department of Energy National Laboratories reveals the size of trees is only part of the equation.
Of equal economic importance, according to scientists from the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) and Oak Ridge National Laboratory (ORNL), is the amount of sugars that can be produced from the ligno-cellulosic biomass that can be converted into fuels.
Scientists have shed new light on a relationship between a sea slug and tiny structures called chloroplasts from their food algae that allow the animals to photosynthesise in a similar way to plants.
The findings, originally posted on bioRxiv* and published today in eLife, add to our understanding of this animal-chloroplast relationship and photosynthetic animals more widely.
Intranasal administration of an anti-inflammatory drug helped reduce disease progression in a preclinical model of multiple sclerosis, according to recent research out of the University of Alberta.
Christopher Power, professor in the Faculty of Medicine & Dentistry, and Leina Saito, a graduate student on his team, showed that delivering an anti-inflammatory drug to mice helped prevent damage to brain cells, effectively slowing the progression of the disease.
New York, NY (October 20, 2020) -- Researchers at Mount Sinai have proposed a groundbreaking new way to study the interaction between complex biological systems in the body and the environment. Their theory suggests the existence of "biodynamic interfaces," an intermediate entity between the two realms, as opposed to conventional approaches that analyze individual aspects of the interaction between the environment and humans in isolation, according to a paper published in BioEssays in October.
As the world grapples with the coronavirus (COVID-19) pandemic, another virus has been raging again in the Democratic Republic of the Congo in recent months: Ebola. Since the first terrifying outbreak in 2013, the Ebola virus has periodically emerged in Africa, causing horrific bleeding in its victims and, in many cases, death.
TAMPA, Fla (Oct. 20, 2020) -- Our immune system's capacity to mount a well-regulated defense against foreign substances, including toxins, weakens with age and makes vaccines less effective in people over age 65. At the same time, research has shown that immunotherapy targeting neurotoxic forms of the peptide amyloid beta (oligomeric Aβ) may halt the progression of Alzheimer's disease, the most common age-related neurodegenerative disease.
Changing the surface chemistry of electrodes leads to the preferential growth of a novel electroactive bacterium that could support improved energy-neutral wastewater treatment.
To grow, electroactive bacteria break down organic compounds by transferring electrons to solid-state substrates outside their cells. Scientists have utilized this process to drive devices, such as microbial electrochemical systems, where the bacteria grow as a film on an electrode, breaking down the organic compounds in wastewater and transferring the resultant electrons to the electrode.
Spotting, pursuing and catching prey - for many animals this is an essential task for survival. Scientists at the Max Planck Institute of Neurobiology now show in zebrafish that the localization of neurons in the midbrain is adapted to a successful hunting sequence.
Month-on-month, year-on-year, the world continues to experience record high temperatures. In response to this and exacerbated by a growing global population, it is expected that air-conditioning demand will continue to rise. A new IIASA-led study explored the pros and cons of seawater air-conditioning as an alternative cooling solution.
Cochlear implants are a groundbreaking technology that has changed the lives of many people living with severe to profound hearing loss.
University of Sydney School of Biomedical Engineering researcher, Dr Greg Watkins, hears with the assistance of two cochlear implants after experiencing profound deafness in both ears following a 30-year career as an electrical engineer. Despite his profound deafness, with the help of his cochlear implant he has been able to complete a PhD in biomedical engineering.
Concentration of dinitrogen oxide - also referred to as nitrous oxide - in the atmosphere increases strongly and speeds up climate change. In addition to CO2 and methane, it is the third important greenhouse gas emitted due to anthropogenic activities. Human-made nitrous oxide emissions are mainly caused by the use of fertilizers in agriculture. Growing demand for food and feed in future might further increase the emissions. This is one finding of an international study published in Nature, in which Karlsruhe Institute of Technology (KIT) was one of the partners.
The Landau's theory of Fermi liquid (FL) (Note 1), established in the first half of the 20th century, is the foundation of the scientific and industrial usage of the metallic materials in our society. It is also the basis of our current understanding of metals. However, in the second half of the 20th century, more and more metallic materials were discovered which behave very differently. The non-Fermi liquid (NFL) behaviour of these "strange metals" remains a puzzle to physicists, and there is no established theory to explain them.
