Researchers capture moving object with ghost imaging
Researchers have developed a way to capture moving objects with the unconventional imaging method known as ghost imaging. The new method could make the imaging technique practical for new applications such as biomedical imaging, security checks and video compression and storage.
Distant worlds under many suns
An astrophysicist has discovered many new multiple star systems that contain exoplanets. For this, he searched more than 1,300 exoplanet host stars. He found that 15 per cent of those stars have at least one companion star, which is only about half the frequency expected for solar like stars. This could indicate that the influence of several stars in a system disrupts the process of planet formation.
Insulin can increase mosquitoes' immunity to West Nile virus
A discovery has the potential to inhibit the spread of West Nile virus as well as Zika and dengue viruses. The researchers demonstrated that mammalian insulin activated an antiviral immunity pathway in mosquitoes, increasing the insects' ability to suppress the viruses. Since mosquito bites are the most common way humans are infected with West Nile, stopping the virus among the insects would protect human health.
Could cytotoxic T-cells be a key to longevity?
Scientists have used single-cell RNA analysis to find that supercentenarians -- meaning people over the age of 110 -- have an excess of a type of immune cell called cytotoxic CD4 T-cells.
Environmental cost of cryptocurrency mines
Bitcoin, Ethereum, Litecoin and Monero -- the names of digital-based 'cryptocurrencies' are being heard more and more frequently. But despite having no physical representation, could these new methods of exchange actually be negatively impacting our planet? It's a question being asked by researchers who are investigating the environmental impacts of mining cryptocurrencies.
