U.S. hospital admissions for non-COVID-19 have only partially rebounded from initial decline

#zrodlo
While declines in U.S. hospital admissions during the onset of COVID-19 has been well-documented, little is known about how admissions during the rebound varied by age, insurance coverage and socioeconomic groups. The decline in non-COVID-19 admissions was similar across all demographic subgroups but the partial rebound that followed shows that non-COVID-19 admissions for residents from Hispanic neighborhoods was significantly lower than for other groups.

Scientists discover why tarantulas come in vivid blues and greens

#zrodlo
Researchers find support for new hypotheses: that tarantulas' vibrant blue colors may be used to communicate between potential mates, while green coloration confers the ability to conceal among foliage. Their research also suggests that tarantulas are not as color-blind as previously believed, and that these arachnids may be able to perceive the bright blue tones on their bodies.

Remote neuropsychology tests for children shown effective, study finds

#zrodlo
Administering neuropsychology evaluations to children online in the comfort of their own homes is feasible and delivers results comparable to tests traditionally performed in a clinic, a new study indicates. The finding could help expand access to specialists and reduce barriers to care, particularly as the popularity of telemedicine grows during the COVID-19 pandemic.

Camera traps show impact of recreational activity on wildlife

#zrodlo
The COVID-19 pandemic has fired up interest in outdoor activities in our parks and forests. Now a new study highlights the need to be mindful of how these activities may affect wildlife living in protected areas. All wildlife tended to avoid places that were recently visited by recreational users. And they avoided mountain bikers and motorized vehicles significantly more than they did hikers and horseback riders.

Researchers examine COVID-19 impact on manufacturing

#zrodlo
A new study finds that manufacturing response to COVID-19 has been largely reactive and uncoordinated, and many firms' crisis communication plans do not include managing an infectious-disease outbreak.

New possibilities for working with quantum information

#zrodlo
The spin of particles can be manipulated by a magnetic field. This principle is the basic idea behind magnetic resonance imaging as used in hospitals. A surprising effect has now been discovered in the spins of phosphorus atoms coupled to microwaves: If the atoms are excited, they can emit a series of echoes. This opens up new ways of information processing in quantum systems.

COVID-19: Berlin scientists lay basis for a passive vaccination

#zrodlo
Researchers have identified highly effective antibodies against the coronavirus SARS-CoV-2 and are now pursuing the development of a passive vaccination. In this process, they have also discovered that some SARS-CoV-2 antibodies bind to tissue samples from various organs, which could potentially trigger undesired side effects.

Uncovering a 'suPAR' culprit behind kidney injury in COVID-19

#zrodlo
A new observational study finds patients in the hospital for COVID-19 have high levels of soluble urokinase receptor (suPAR), an immune-derived pathogenic protein that is strongly predictive of kidney injury.

Y chromosomes of Neanderthals and Denisovans now sequenced

#zrodlo
An international research team led by Martin Petr and Janet Kelso of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, has determined Y chromosome sequences of three Neandertals and two Denisovans. These Y chromosomes provide new insights into the relationships and population histories of archaic and modern humans, including new evidence for ancient gene flow from early modern humans into Neandertals.
