Nanoimaging the intracellular space to aid drug development

Iridium-based metallodrugs

Iridium-based metallodrugs are emerging as novel tools to destroy cancer cells by disrupting their intracellular redox balance. Scientists at IMDEA Nanociencia and researchers at ALBA, ESRF and CNB-CSIC have joined efforts to image the anticancer agent at work in the cryopreserved intracellular nano-space. Chemotherapeutics are key players in the clinical setting to fight most types … Read more Nanoimaging the intracellular space to aid drug development

Western University researchers begin work on COVID-19 vaccine

COVID-19

A multidisciplinary team of Western University researchers is beginning work on the development of a COVID-19 vaccine. They join the global effort to curb the spread of the virus which to-date has been confirmed in 225,000 cases worldwide, and has caused more than 9,000 deaths. The team is rapidly mobilizing its efforts to establish and … Read more Western University researchers begin work on COVID-19 vaccine

Lava flows tell 600-year story of biodiversity loss on tropical island

A natural experiment created by an active volcano gives new insight into the long-term negative impacts of human colonisation of tropical forest islands. The findings are published in the British Ecological Society journal, Journal of Ecology. Researchers from the University of Réunion island surveyed vegetation on more than 600 years of lava flows on the slopes … Read more Lava flows tell 600-year story of biodiversity loss on tropical island

USU herpetologist reports surprising evolutionary shift in snakes

In the animal kingdom, survival essentially boils down to eat or be eaten. How organisms accomplish the former and avoid the latter reveals a clever array of defense mechanisms. Maybe you can outrun your prey. Perhaps you sport an undetectable disguise. Or maybe you develop a death-defying resistance to your prey’s heart-stopping defensive chemicals that … Read more USU herpetologist reports surprising evolutionary shift in snakes

We must prioritise the protection of ecosystems

Prioritising and tracking the protection of countries’ ecosystems – from wetlands to reefs, forests and more – is critical to protecting Earth’s biodiversity. That’s the plea from The University of Queensland and the Wildlife Conservation Society’s Professor James Watson, as policy makers from 190 nations prepare to meet in Rome next week to develop the … Read more We must prioritise the protection of ecosystems

Improving assessments of an endangered lion population in India

An alternative method for monitoring endangered lions in India could improve estimates of their abundance and help inform conservation policy and management decisions. Keshab Gogoi and colleagues at the Wildlife Institute of India present their findings in the open-access journal PLOS ONE on February 19, 2020. Conservation practices have enabled Asiatic lions to recover from a population … Read more Improving assessments of an endangered lion population in India

Global relationships that determine bird diversity on islands uncovered

The study, a collection of molecular data from bird species found across 41 oceanic archipelagos, reveals how the area and isolation of islands are key to determining the diversity of species they contain. It is known that biodiversity is unevenly distributed across the planet. But why do some islands such as the Galápagos and Hawaii … Read more Global relationships that determine bird diversity on islands uncovered

Sweet beaks: What Galapagos finches and marine bacteria have in common

The variety of finch species on the remote Galapagos Islands is the most prominent example for Charles Darwin’s and Alfred R. Wallace’s theory of evolution through natural selection. Galapagos finch species have developed distinct beak sizes and shapes and thereby have adapted to different food sources. This exemplifies how even closely related species can effectively … Read more Sweet beaks: What Galapagos finches and marine bacteria have in common

What birdsong tells us about brain cells and learning

Most scientists who study the brain believe that memories are stored through networks of synapses, or connections that form between neurons. Learning takes place as neurons form new connections and strengthen or weaken existing ones, giving the brain its so-called synaptic plasticity. There is growing evidence, however, that the intrinsic, built-in properties of the cells … Read more What birdsong tells us about brain cells and learning

Biodiversity scientists pull together to document how life works before it’s too late

Time is running out to predict how potential climate futures will impact biodiversity and the functioning of our biosphere. To save and predict the future of biodiversity we need to rapidly accelerate our understanding of the planet’s diverse forms of life. A new, global network of international researchers is using the power of open source … Read more Biodiversity scientists pull together to document how life works before it’s too late
