Novel electrode for improving flowless zinc-bromine battery

The flowless zinc-bromine battery (FLZBB) is a promising alternative to flammable lithium-ion batteries due to its use of non-flammable electrolytes. However, it suffers from self-discharge due to the crossover of active materials, generated at the positive graphite felt (GF) electrode, to the negative electrode, significantly affecting performance. Now, researchers have developed a novel nitrogen-doped mesoporous carbon-coated GF electrode that effectively suppresses self-discharge. This breakthrough can l Read more ›

Groundcherry gets genetic upgrades: Turning a garden curiosity into an agricultural powerhouse

Imagine a small fruit that tastes like a cross between a tomato and a pineapple, wrapped in its own natural paper lantern. That's the groundcherry (Physalis grisea) -- a little-known relative of tomatoes that's been quietly growing in gardens and small farms across North America for centuries. Now, this humble fruit is getting a 21st-century upgrade thanks to some cutting-edge genetic research. Read more ›

PEPITEM -- a novel protective agent for 'inflammageing'

A naturally occurring peptide called PEPITEM could potentially rejuvenate the immune response in older individuals and protect against 'inflammageing', which is widely believed to be the root cause of many age-related diseases. A study raises the exciting possibility of a protective agent that could dampen age-related inflammation and restore normal immune function in older adults. Read more ›

Although tiny, peatland microorganisms have a big impact on climate

Polyphenols are generally toxic to microorganisms. In peatlands, scientists thought microorganisms avoided this toxicity by degrading polyphenols using an oxygen-dependent enzyme, and thus that low-oxygen conditions inhibit microbes' carbon cycling. However, a new study found that Arctic peatland microorganisms used alternative enzymes, with and without oxygen, to break down polyphenols. This suggests carbon stored in these ecosystems is more at risk than previously thought. Read more ›

Improving HIV treatment in children and adolescents -- the right way

Globally, around 2.6 million children and adolescents are currently living with HIV, the majority of them in Africa. These young people are much more likely to experience treatment failure than adults. Experts long assumed that testing for viral drug resistance could improve treatment in cases where treatment has failed. However, a research team now shows that it is much more important to support patients in taking their medication regularly. Read more ›

Does the type of workstation you use make a difference in your health and productivity?

Although devices such as standing desks have been found to alleviate physical symptoms and increase worker productivity, questions remain regarding the best use of the primary types of workstations -- stand-biased, sit-stand or traditional -- for increasing workers' physical activity and preventing health problems. To answer these questions, researchers measured the computer usage and activity levels of 61 office workers for 10 days to evaluate any discomfort and develop possible... Read more ›

Autoantibodies behind lifelong risk of viral infections

A new study shows that about two percent of the population develop autoantibodies against type 1 interferons, mostly later in life. This makes individuals more susceptible to viral diseases like COVID-19. The study is based on an analysis of a large collection of historical blood samples. Read more ›
