A global study has found the key to mapping biodiversity has been staring us in the face the whole time: in the surrounding air. Led by Finland’s University of Jyväskylä, the paper 'Airborne DNA reveals predictable spatial and seasonal dynamics of fungi' is published in the journal Nature. Only a fraction of nature’s diversity, or species richness, is still known, especially when it comes to insects and fungi, both of which have millions of species still [...]

Already at the beginning of the COVID-19 pandemic, a group of Brazilian researchers pioneered in showing why SARS-CoV-2 infection tends to be more severe in diabetic patients. Now, the same team based at the Institute of Biology of the State University of Campinas (IB-UNICAMP) has discovered one of the reasons why obese people who do not have diabetes or even insulin resistance also have an increased risk of developing the severe form of the disease. "New experiments show that the [...]

Researchers from the Butantan Institute and collaborators are developing a more potent version of the BCG vaccine that protects against tuberculosis. While the conventional immunizer reduced infection by 90% in experiments with mice, the so-called recombinant BCG increased the protection rate to 99%. In addition, the new formulation protected the animals for a significantly longer period of time. "BCG is the first vaccine we receive at birth, and it's indeed effective in [...]

Luminescence refers to the result of a process in which an object absorbs light at one wavelength and then re-emits it at another wavelength. Through light absorption, electrons in the ground state of the material are excited to a higher energy state. After a certain amount of time characteristic of each excited state, the electrons decay to lower energy states, including the ground state, and emit light. The phenomenon is used in a wide array of technological applications involving highly [...]

Short bursts of exercise that last one minute or less could be beneficial for people who struggle to exercise regularly, an expert has said. It is suggested that the intense bouts – described as “exercise snacks” – could be particularly useful for bolstering the health and fitness of those who spend a lot of time sitting, such as obese people or those with chronic diseases. Examples used by Bruno Gualano, an associate professor at the Centre of Lifestyle Medicine [...]

Researchers at the Optics and Photonics Research Center (CePOF) in Brazil and collaborators at the University of Toronto and Princess Margaret Cancer Center in Canada have reported for the first time the effective use of a specific type of phototherapy to eradicate ocular melanoma in mice. Based on pulsed laser, the technique involves the application of a large amount of light in a short period of time to activate a drug. CePOF is a Research, Innovation and Dissemination Center [...]

Scientists at the State University of Campinas (UNICAMP) in Brazil and the University of Cadiz (UCA) in Spain have successfully deployed a novel method of extracting high-value-added chemical compounds from the peel of jabuticaba (Plinia cauliflora). The method, which simplifies the process and enhances its efficiency, is described in an article published in Journal of Food Composition and Analysis. The aim was to optimize extraction of anthocyanin, a potent antioxidant found in [...]
