Nanocarbons for purifying water get a lot more efficient by exposing a precursor mixture to high voltage.

A new study has shown evidence of undetected concentrations and flows of dissolved organic matter entering Arctic coastal waters coming from groundwater flows on top of frozen permafrost. This water moves from land to sea unseen, but researchers now believe it carries significant concentrations of carbon and other nutrients to Arctic coastal food webs.
Egyptian blue is one of the oldest humanmade colour pigments. It adorns the crown of the world famous bust of Nefertiti: but the pigment can do even more. An international research team has produced a new nanomaterial based on the Egyptian blue pigment, which is ideally suited for applications in imaging using near infrared spectroscopy and microscopy.
The virus that causes COVID-19 remains for several hours to days on surfaces and in aerosols, a new scientific study has found. The study suggests that people may acquire the coronavirus through the air and after touching contaminated objects.
The few thousand galaxies closest to us move in a vast 'bubble' that is 250 million light years in diameter, where the average density of matter is half as large as for the rest of the universe. This is the hypothesis put forward by a theoretical physicist to solve a conundrum that has been splitting the scientific community for a decade: at what speed is the universe expanding?
A new device enables researchers to observe hundreds of neurons in the brain in real-time. The system is based on modified silicon chips from cameras, but rather than taking a picture, it takes a movie of the neural electrical activity.
The dynamics of electrons changes ever so slightly on each interaction with a photon. Physicists have now measured such interplay in its arguably purest form -- by recording the attosecond-scale time delays associated with one-photon transitions in an unbound electron.
The rapid pace of climate change threatens all living species. An international team of researchers has demonstrated that fish living in the Baltic Sea evolve using epigenetic mechanisms, yet to a lesser extent than previously hypothesized.
Researchers have come up with a way of getting conductive polymer gels to adhere to wet surfaces.
A new method to accurately record brain activity at scale has been developed. The technique could lead to new medical devices to help amputees, people with paralysis or people with neurological conditions such as motor neuron disease.
Key factors must be taken into account in determining the need for and allocation of scarce ventilators during a severe pandemic, especially one causing respiratory illness.
