COVID-19: Air quality influences the pandemic
An interdisciplinary team from the University of Geneva and the ETH Zürich spin-off Meteodat investigated possible interactions between acutely elevated levels of fine particulate matter and the virulence of the coronavirus disease. Their results suggest that high concentrations of particles less than 2.5 micrometers in size may modulate, or even amplify, the waves of SARS-CoV-2 contamination and explain in part the particular profile of the COVID-19 pandemic.

Galaxy encounter violently disturbed Milky Way, study finds
The long-held belief that the Milky Way, the galaxy containing Earth and the solar system, is relatively static has been ruptured by fresh cosmic insight. The spiral-shaped disc of stars and planets is being pulled, twisted and deformed with extreme violence by the gravitational force of a smaller galaxy - the Large Magellanic Cloud (LMC).

Which particulate air pollution poses the greatest health risk?
Researchers at the Paul Scherrer Institute PSI, together with colleagues from several other European institutions, have investigated whether particulate matter from certain sources can be especially harmful to human health. They found evidence that the amount of particulate matter alone is not the greatest health risk. Rather, it could be the so-called oxidative potential that makes particulate pollution so harmful. They are publishing their results today in the scientific journal Nature. (2020-11-18)

Early details of brain damage in COVID-19 patients
Looking at six patients using a specialized magnetic resonance technique, researchers at Massachusetts General Hospital found that COVID-19 patients with neurological symptoms show some of the same metabolic disturbances in the brain as other patients who have suffered oxygen deprivation from other causes, but there are also notable differences.

COVID-19 shutdown effect on air quality mixed
In April 2020, as remote work and social distancing policies were in place in Delaware and a number of other states, there was a sense the skies were clearer and less polluted with fewer people on the road. But new research from a team led by University of Delaware, Penn State and Columbia University researchers found a murkier picture. (2020-11-12)

Dark matter from the depths of the universe
Cataclysmic astrophysical events such as black hole mergers could release energy in unexpected forms. Exotic low-mass fields (ELFs), for example, could propagate through space and cause feeble signals detectable with quantum sensor networks such as the atomic clocks of the GPS network or the magnetometers of the GNOME network. These results are particularly interesting in the context of the search for dark matter, as low-mass fields are regarded as promising candidates for this exotic form of matter. (2020-11-11)

Black hole or no black hole: On the outcome of neutron star collisions
A new study lead by GSI scientists and international colleagues investigates black-hole formation in neutron star mergers. Computer simulations show that the properties of dense nuclear matter play a crucial role, which directly links the astrophysical merger event to heavy-ion collision experiments at GSI and FAIR. These properties will be studied more precisely at the future FAIR facility. The results have now been published in Physical Review Letters. (2020-11-10)

Has the hidden matter of the universe been discovered?
Astrophysicists consider that around 40% of the ordinary matter that makes up stars, planets and galaxies remains undetected, concealed in the form of a hot gas in the complexe cosmic web. Today, scientists at the Institut d'Astrophysique Spatiale (CNRS/Université Paris-Saclay) may have detected, for the first time, this hidden matter through an innovative statistical analysis of 20-year-old data. Their findings are published on November 6, 2020 in Astronomy & Astrophysics. (2020-11-06)

Urban air pollution estimates may overshadow full picture for China
For the first time, researchers have compared air pollution in urban and suburban areas across all of China. Using data from the China National Environmental Monitoring Center (CNEMC), the researchers found that one air pollutant, called particulate matter (PM2.5), may be overestimated in winter, while another pollutant, called ozone (O3), is significantly underestimated.

From hard to soft: making sponges from mussel shells
Scientists have discovered a spongy form of calcium carbonate (CaCO3), a material found in limestone, chalk, marble, and the shells of mussels and other shellfish. While most forms of calcium carbonate are hard minerals, this new form is soft and absorbent. The researchers, reporting November 5 in the journal Matter, made the discovery while exploring new uses for leftover mussel shells. (2020-11-05)

Thermal vision of snakes inspires soft pyroelectric materials
Converting heat into electricity is a property thought to be reserved only for stiff materials like crystals. However, researchers--inspired by the infrared (IR) vision of snakes--developed a mathematical model for converting soft, organic structures into so-called 'pyroelectric' materials. The study, appearing October 21, 2020 in the journal Matter, proves that soft matter can be transformed into a pyroelectric material and potentially solves a long-held mystery surrounding the mechanism of IR vision in snakes.

COVID-19 lockdowns averted tens of thousands of premature deaths related to air pollution
Scientists at Notre Dame found that particulate matter concentrations in China dropped by an unprecedented 29.7 percent, and by 17.1 percent in parts of Europe, during lockdowns that took place between Feb. 1 and March 31 in China and Feb. 21 to May 17 in Europe. (2020-10-14)

The puzzle of the strange galaxy made of 99.9% dark matter is solved
At present, the formation of galaxies is difficult to understand without the presence of a ubiquitous, but mysterious component, termed dark matter. Astronomers have measure how much dark matter there is around galaxies, and have found that it varies between 10 and 300 times the quantity of visible matter. However, a few years ago, the discovery of a very diffuse object, named Dragonfly 44, changed this view. (2020-10-13)

Winners and losers of energy transition
Drastically reducing greenhouse gas emissions in the electricity sector could have substantial economic and social impacts. Some regions might benefit more than others from new employment opportunities and from reduced air pollution, while others face threats to employment. Such a transition to renewable electricity thus risks creating new regional winners and losers. In a study published in Nature Communications, scientists from the University of Geneva (UNIGE) quantify regional impacts associated with Central European electricity targets. (2020-10-13)

School absences correlate to impaired air quality
In Salt Lake City schools, absences rise when the air quality worsens, and it's not just in times of high pollution or ''red'' air quality days--even days following lower levels of pollutions saw increased absences. (2020-10-09)

Evidence of Alzheimer's, Parkinson's & MND in brains of young people exposed to dirty air
After examining the brainstems of 186 young Mexico City residents aged between 11 months and 27 years of age, researchers, including Professor Barbara Maher from Lancaster University, found markers not only of Alzheimer's disease, but also of Parkinson's and of motor neurone disease (MND) too. These markers of disease were coupled with the presence of tiny, distinctive nanoparticles within the brainstem - their appearance and composition indicating they were likely to come from vehicle pollution.

Enforcement more effective than financial incentives in reducing harmful peat fires?
A new study looking at incentives to reduce globally harmful peatland fires suggests that fear of enforcement and public health concerns influence behaviour more than the promise of financial rewards. The findings come as wildfires devastate the US West Coast and Russian Arctic, and fire season begins in Australia, Indonesia and Brazil. (2020-09-30)
