An article recently published in Science, entitled “The global tree restoration potential”, presents what it calls “the most effective solution at our disposal to mitigate climate change”. The lead author is Jean-François Bastin, an ecologist affiliated with the Swiss Federal Institute of Technology (ETH Zurich). The article attracted enormous media attention. It reports the results of a study in which Bastin and collaborators used remote sensing and modeling [...]

Een onderzoeksgroep van Braziliaanse en Japanse wetenschappers heeft ontdekt hoe luciferase wordt geproduceerd door de spoorwegworm Phrixothrix hirtus straalt rood licht uit. Luciferase is een enzym dat de oxidatie van luciferine in vuurvliegjes katalyseert, oxyluciferine produceert en vuurvliegjes in staat stelt licht uit te stralen. Verschillen in de moleculaire structuren verklaren de verschillende kleuren van deze bioluminescentie in verschillende soorten. Deze ontdekking heeft het [...]

Fungi of the genus Candida cause thrush and candidiasis, a fairly common disease in humans. It can be lethal to individuals with low immunity, especially when they are hospitalized. Although the drug is widely used to combat the disease, it is effective in most cases, some varieties of the fungus are drug-resistant. Compounds that combat two species of Candida have now been isolated from a plant by researchers based in Brazil and Spain. The plant is Mimosa caesalpiniifolia, a shrub native to [...]

Exercise immediately prior to and during pregnancy restores important tissues in the body, making them better able to control blood sugar levels and reducing the risk of long-term health problems, new research in mice suggests. Researchers from the University of Cambridge, who led the study published today in the journal Physiological reports, say the findings underline the importance of an active lifestyle in planning a pregnancy. In the UK, more than half of all women are of reproductive [...]

Researchers and caregivers have famous that excessive daytime sound asleep can expand lengthy earlier than the reminiscence complications linked to Alzheimer's disease start to spread. Prior reports have regarded this excessive daylight drowsing to be compensation for poor midnight sleep led to via Alzheimer's-associated disruptions in sleep-advertising mind regions, at the same time as others have argued that the sleep problems themselves give a contribution to the development of the [...]

The incidence of thyroid cancer among first responders who worked voluntarily or as fire brigade, rescue and cleaning personnel at Ground Zero in New York on or after September 11, 2001 is three times higher than in the general population. This difference has been confirmed by a method with a panel of four biomarkers that distinguish benign and malignant cases of thyroid cancer based on gene expression. The tests have been developed by researchers from the Federal University of São [...]

Heat flows from warm to cold objects. When a warm and a cold body are in thermal contact, they exchange heat energy until they reach a thermal equilibrium, whereby the warm body cools and the cold body warms up. This is a natural phenomenon that we experience all the time. This is explained by the second law of thermodynamics, which states that the total entropy of an isolated system always tends to rise over time until it reaches a maximum. Entropy is a quantitative measure of the disorder in [...]

Measuring the blood plasma ranges of an enzyme referred to as PDIA1 might sooner or later grow to be a way of diagnosing an individual’s predisposition to heart problems even when they’re wholesome, i.e., not overweight, diabetic or a smoker, and with regular ldl cholesterol. That is recommended by a research printed within the journalRedox Biologyby Brazilian researchers affiliated with the College of São Paulo (USP), the College of Campinas (UNICAMP) and Butantan [...]
