The anxiety, stress and worry brought on by COVID-19 is not limited to daytime hours. The pandemic is affecting our dreams as well, infusing more anxiety and negative emotions into dreams and spurring dreams about the virus itself, particularly among women, according to new research.

People of Asian ancestry face yet another set of challenges posed by racism and xenophobia which has soared during the COVID-19 pandemic.

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.

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.

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.

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.

A world-first study has found that severely overweight people are less likely to be able to re-wire their brains and find new neural pathways, a discovery that has significant implications for people recovering from a stroke or brain injury.

Paradox-free time travel is theoretically possible, according to the mathematical modelling of an undergraduate student.

Geometric storm patterns on Jupiter's south pole have been a mystery to scientists, but researchers may have uncovered how they form.

A comprehensive search of genetic variation databases has revealed no significant differences across populations and ethnic groups in seven genes associated with viral entry of SARS-CoV-2.

Gravity can accelerate the homogenization of space-time as the universe evolves.

Scientists have spotted a once-in-a-century climate anomaly during World War I that likely increased mortality during the war and the influenza pandemic in the years that followed.

For people still employed during the COVID-19 pandemic, job insecurity and financial concern are associated with greater symptoms of depression and anxiety, according to a new study.

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.

Astronomers are warning that orbital debris posing a threat to operational satellites is not being monitored closely enough, as they publish a new survey finding that over 75% of the orbital debris they detected could not be matched to known objects in public satellite catalogues.

Physicists have published a review that explores Bell's inequalities and his concepts of reality and explains their relevance to quantum information and its applications.

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.

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.

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.

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.
