A new type of dressing is shaping up as a way to heal chronic wounds without the need for antibiotics. Using a helium plasma jet to activate hydrogel, researchers have created a highly effective antibacterial cover that can swiftly overpower wounds.
-
Researchers have devised an economical way of reducing the environmental impact of both the steel and aluminum industries by using hydrogen to melt down the toxic red mud left over from aluminum production to produce green steel in around 10 minutes.
-
Researchers have used plasma technology to transform blue-green microalgae into a novel coating that can be applied to dressings and medical devices to protect patients from infection, speed up healing and reduce inflammation.

A team of scientists led by University of Virginia professor Patrick Hopkins is developing a plasma "freeze ray" that will be less interesting to super villains than to engineers looking for ways to cool electronics in the vacuum of space.

Solar wind – charged particles from the Sun – pervades our solar system, but the exact mechanism behind it remains murky. Now ESA’s Solar Orbiter spacecraft has observed previously unknown tiny flares on the Sun’s surface spewing plasma into space.

A world-first clinical trial has found blood or plasma donations can reduce levels of toxic PFAS chemicals by up to 30 percent. The trial is the first to find an effective intervention that reduces blood levels of substances known as “forever chemicals”.
-
Scientists have discovered a new form of space weather – superfast electron rains that precipitate into the atmosphere from the radiation belts. The rains could affect satellites, spacecraft and astronauts, but aren’t accounted for in current models.
-
The results of a major trial testing convalescent plasma therapy for COVID-19 in high-risk outpatients have been peer-reviewed and published. The once-promising therapy was found to be ineffective in preventing disease progression in high-risk patients.
-
Bacterial infections of the middle ear are quite common, particularly in children, yet they can be difficult to treat. An experimental new device has been designed to help, by zapping the bacteria with plasma.
-
More than 40 years after launch, Voyager 1 is still making new discoveries. The latest achievement by the craft is the detection of a faint, plasma “hum,” indicating that there may be more activity in interstellar gas than previously thought.
-
A clinical trial run by the NIH exploring the efficacy of convalescent plasma in treating mild to moderate COVID-19 patients has been halted. In a similar conclusion to prior trials, the once-promising treatment was deemed unlikely to be of any benefit.
-
Scientists have found evidence of a “space hurricane” for the first time. The storm, made up of swirling clouds of plasma, raged in Earth’s upper atmosphere for hours, dumping huge amounts of electrons like rain in a system that resembles a regular hurricane.
