Scientists have called for a concerted global effort to stem the tide of disposable electronic technologies – such as vapes – contributing to international waste accumulation and environmental degradation. Writing in the journal Science, researchers from across the UK have highlighted how disposable vape sales quadrupled in the UK between 2022 and 2023, with consumers now throwing away around 5 million devices each week. In the United States, 4.5 disposable vapes are thrown away each second, and it is fast becoming an issue replicated right across the world. One of the main upshots, scientists say, is that vapes and other disposable ...

A new study published online today, April 25, in the scientific journal Science provides the strongest evidence to date that not only is nature conservation successful, but that scaling conservation interventions up would be transformational for halting and reversing biodiversity loss—a crisis that can lead to ecosystem collapses and a planet less able to support life—and reducing the effects of climate change. The findings of this first-ever comprehensive meta-analysis of the impact of conservation action ...

For most human proteins, there are no small molecules known to bind them chemically (so called “ligands”). Ligands frequently represent important starting points for drug development but this knowledge gap critically hampers the development of novel medicines. Researchers at CeMM, in a collaboration with Pfizer, have now leveraged and scaled a method to measure the binding activity of hundreds of small molecules against thousands of human proteins. This large-scale study revealed tens of thousands of ligand-protein interactions that can now be explored for the development of chemical tools and therapeutics. Moreover, ...

What happens in the body when we are hungry and see and smell food? A team of researchers at the Max Planck Institute for Metabolism Research has now been able to show in mice that adaptations in the liver mitochondria take place after only a few minutes. Stimulated by the activation of a group of nerve cells in the brain, the mitochondria of the liver cells change and prepare the liver for the adaptation of the sugar metabolism. The findings, published in the journal Science, could open up new avenues for the treatment of type 2 diabetes. The researchers ...

Global biodiversity has declined between 2% and 11% during the 20th century due to land-use change alone, according to a large multi-model study published in Science. The projections show that climate change could become the main driver of biodiversity decline by the mid-21st century. Land-use change is considered the largest driver of biodiversity change, according to the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES). However, scientists are divided over how much biodiversity has changed in past decades. To better answer this question, an international team of researchers modeled the impacts of land-use change ...

Companies’ emissions reduction targets should not be the sole measure of corporate climate ambition, according to a new perspective paper. Relying on emissions can favour more established companies and hinder innovation, say the authors, who suggest updating regulations to improve corporate climate action. The paper, published today in Science, is by an international team led by Utrecht University, which includes Imperial College London researchers. Lead author of the study Dr Yann Robiou Du Pont, from the Copernicus Institute of Sustainable Development at Utrecht ...

Exploratory behavior is one of the fundamental personality traits of animals – and these traits influence their probability of survival, among other things. For example, curious individuals can inhabit different areas in their habitats compared to more cautious conspecifics. At the same time, however, they expose themselves to a greater risk of being discovered and eaten. Exploratory behavior as a factor in evolution The cichlids of Africa’s Lake Tanganyika exhibit extraordinary diversity in terms ...

Climate change is a global phenomenon, but its impacts are felt at a very local level. Take, for example, dust. Dust can have a huge impact on local air quality, food security, energy supply and public health. Yet, little is known about how global climate change is impacting dust levels. Previous studies have found that dust levels are actually decreasing across India, particularly northern India, the Persian Gulf Coast and much of the Middle East, but the reason has remained unclear. Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) are working to understand how ...

Oil is an important natural resource for many industries, but it can lead to serious environmental damage when accidentally spilled. While large oil spills are highly publicized, every year there are many smaller-scale spills into lakes, rivers and oceans. And, according to research published in ACS’ Energy & Fuels, the longer that oil remains in freshwater, the more chemical changes it undergoes, creating products that can persist in the environment. Approximately 600,000 gallons of oil were accidentally spilled into the environment ...

LOS ANGELES — More than 660 Nevadans need an organ transplant, according to Nevada Organ Network, a federally designated organ procurement organization; but many currently struggle to access care because of limited transplant services available in Nevada.   Amid the growing need for additional transplant services in the state, Keck Medicine of USC has opened a new location in Las Vegas that will provide specialized care for patients in Las Vegas and surrounding communities who need a liver or heart transplant.   The clinic is the first in Nevada to offer ...

Chemokines are signalling proteins that orchestrate the interaction of immune cells against pathogens and tumours. To understand this complex network, various techniques have been developed to identify chemokine-producing cells. However, it has not yet been possible to determine which cells react to these chemokines. Researchers at the University Hospital Bonn (UKB) and the University of Bonn have developed a new class of genetically modified mice that enables the simultaneous identification of chemokine producers and sensors. Using the chemokine ...
