A new way to study HIV's impact on the brain

Friday March 27th, 2020 09:04:41 PM
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.

Double-walled nanotubes have electro-optical advantages

Friday March 27th, 2020 08:17:22 PM
Theorists find that flexoelectric effects in double-walled carbon nanotubes could be highly useful for photovoltaic applications.

Quantum copycat: Researchers find a new way in which bosons behave like fermions

Friday March 27th, 2020 08:17:20 PM
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.

In Earth's largest extinction, land animal die-offs began long before marine extinction

Friday March 27th, 2020 08:17:18 PM
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 before the rapid marine extinction 252 million years ago.

UK local authorities not ready for the number of deaths from Covid-19

Friday March 27th, 2020 06:15:26 PM
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.

Copper boosts pig growth, and now we know why

Friday March 27th, 2020 06:15:22 PM
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 the entire diet.

Gene mutation enhances cognitive flexibility in mice

Friday March 27th, 2020 06:15:18 PM
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.

Seafloor of Fram Strait is a sink for microplastic from Arctic and North Atlantic Ocean

Friday March 27th, 2020 06:15:17 PM
Working in the Arctic Fram Strait, scientists have found microplastic throughout the water column with particularly high concentrations at the ocean floor.

Standardizing COVID-19 data analysis to aid international research efforts

Friday March 27th, 2020 04:23:15 PM
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.

ALMA resolves gas impacted by young jets from supermassive black hole

Friday March 27th, 2020 03:37:55 PM
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 of galaxies in the early Universe.

How to boost immune response to vaccines in older people

Friday March 27th, 2020 03:37:52 PM
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 tailor the make-up of vaccines for older people.

Light funnel apparatus created

Friday March 27th, 2020 03:37:49 PM
Physicists have developed a light funnel apparatus. It could serve as a new platform for hypersensitive optical detectors.

COVID-19 linked to cardiac injury, worse outcomes for patients with heart conditions

Friday March 27th, 2020 03:37:43 PM
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.

Scientists predict the size of plastics animals can eat

Friday March 27th, 2020 03:37:02 PM
A team of scientists has, for the first time, developed a way of predicting the size of plastics different animals are likely to ingest.

Animals keep viruses in the sea in balance

Friday March 27th, 2020 03:36:58 PM
A variety of sea animals can take up virus particles while filtering seawater for oxygen and food. Sponges are particularly efficient.

A new battery chemistry promises safer high-voltage lithium-ion batteries

Friday March 27th, 2020 03:36:54 PM
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 journeys in electric vehicles possible and lead to the creation of a new generation of home energy storage, both with improved fire safety.

Forgotten tale of phage therapy history revealed

Friday March 27th, 2020 03:36:47 PM
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.

Disasters can affect cervical cancer screening for years

Friday March 27th, 2020 02:41:14 PM
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.

Biophysics: Lifting the lid on beta-barrels

Friday March 27th, 2020 02:41:12 PM
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.
