Using a newly developed laboratory model of three types of brain cells, scientists reveal how HIV infection -- as well as the drugs that treat it -- can take a toll on the central nervous system.

Theorists find that flexoelectric effects in double-walled carbon nanotubes could be highly useful for photovoltaic applications.
When a one-dimensional gas of strongly interacting bosons expands, the velocity distribution of the bosons transforms into one that is identical to non-interacting fermions.
Because of poor dates for land fossils laid down before and after the mass extinction at the end of the Permian, paleontologists assumed that the terrestrial extinctions from Gondwana occurred at the same time as the better-documented marine extinctions. But a new study provides more precise dates for South African fossils and points to a long, perhaps 400,000-year period of extinction on land...
Scientists have developed a new computer simulation model that includes microbubble nucleation to explain the flow slippage of fluids inside pipes. This work may help improve the flow rate of viscous fluids in commercial applications, as in the energy industry.
Even if fatality rates are at the lower end of expectations -- one percent of virus victims -- it is highly likely that death and bereavement services will be overwhelmed.
Pigs have better feed conversion rates with copper in their diets, but until now, scientists didn't fully understand why. Existing research from the University of Illinois shows copper doesn't change fat and energy absorption from the diet. Instead, according to new research, the element seems to enhance pigs' ability to utilize fat after absorption, resulting in increased energy utilization of...
Researchers have discovered in mice what they believe is the first known genetic mutation to improve cognitive flexibility -- the ability to adapt to changing situations.
Working in the Arctic Fram Strait, scientists have found microplastic throughout the water column with particularly high concentrations at the ocean floor.
Researchers have launched a new database to advance the international research efforts studying COVID-19. The publicly-available, free-to-use resource can be used by researchers from around the world to study how different variations of the virus grow, mutate and make proteins.
Researchers have demonstrated a new model of how competing pieces of information spread in online social networks and the Internet of Things (IoT). The findings could be used to disseminate accurate information more quickly, displacing false information about anything from computer security to public health.
Astronomers obtained the first resolved image of disturbed gaseous clouds in a galaxy 11 billion light-years away by using the Atacama Large Millimeter/submillimeter Array (ALMA). The team found that the disruption is caused by young powerful jets ejected from a supermassive black hole residing at the center of the host galaxy. This result will cast light on the mystery of the evolutionary process...
Identifying interventions that improve vaccine efficacy in older persons is vital to deliver healthy aging for an aging population. Immunologists have identified a route for counteracting the age-related loss of two key immune cell types by using genital wart cream to boost immune response to vaccination in aged mice. After this validation in mice, the findings offer an attractive intervention to...
Physicists have developed a light funnel apparatus. It could serve as a new platform for hypersensitive optical detectors.
COVID-19 can have fatal consequences for people with underlying cardiovascular disease and cause cardiac injury even in patients without underlying heart conditions, according to a new review.
A team of scientists has, for the first time, developed a way of predicting the size of plastics different animals are likely to ingest.
A variety of sea animals can take up virus particles while filtering seawater for oxygen and food. Sponges are particularly efficient.
For the first time, researchers who explore the physical and chemical properties of electrical energy storage have found a new way to improve lithium-ion batteries. They successfully increased not only the voltage delivery of a lithium-ion battery but also its ability to suppress dangerous conditions that affect the current range of batteries. This improved lithium-ion battery could make longer...
In the current situation when the fear of virus infections in the public is common, it is good to remember that some viruses can be extremely beneficial for humankind, even save lives. Such viruses, phages, infect bacteria. Recent research shed some light on the phage therapy history. It revealed that Brazil was a strong user and developer of phage therapy in 1920-40's.
Screening is important for the early detection of cervical cancer, but rates were significantly affected, in some areas for years, following a devastating earthquake and tsunami in Japan.
The interaction between biotin and streptavidin is a well-established experimental tool in bionanotechnology. Physicists have now shown that the mechanical stability of the complex is dependent on the precise geometry of the interface.
A research team has developed a new type of solar cell that can both withstand environmental hazards and is 26.7% efficient in power conversion.
A new research highlighted the importance of reducing fossil fuel combustion not only to curb the trend of global warming, but also to improve the quality of China's coastal waters.
Scientists have recently released guidance for prevention and management of COVID-19 among elderly in long term care facilities. The article outlines the objective of WHO interim guidance on Infection Prevention and Control (IPC) in Long-Term Care Facilities (LTCF) in the context of COVID-19 which is to prevent COVID-19-virus from entering the facility, spreading within the facility, and spreading...
A new technique allows researchers to test how the deformation of tiny train track-like cell proteins affects their function. The findings could help clarify the roles of deformed 'microtubules' in traumatic brain injuries and in neurological diseases like Parkinson's.
