Using stem cell-derived heart muscle cells to advance heart regenerative therapy
Regenerative heart therapies involve transplanting cardiac muscle cells into damaged areas of the heart to recover lost function. However, the risk of arrhythmias following this procedure is reportedly high. In a recent study, researchers tested a novel approach that involves injecting 'cardiac spheroids,' cultured from human stem cells, directly into damaged ventricles. The highly positive outcomes observed in primate models highlight the potential of this strategy. 04/26/2024 11:00 AM
Advance in the treatment of acute heart failure identified
A multicenter study has identified a potential new treatment for acute heart failure, a leading cause of hospitalization and death. 04/25/2024 04:15 PM
Early trauma cuts life short for squirrels, and climate change could make matters worse
Life can be tough for young red squirrels living in the Canada's Yukon territory, where frigid winters, food scarcity and predators threaten their long-term survival. Scientists want to know what factors might protect young squirrels, especially as their environment becomes more impacted by climate change. 04/25/2024 04:15 PM
RNA modification is responsible for the disruption of mitochondrial protein synthesis in Alzheimer's disease
A team of researchers has identified a mechanism that causes mitochondrial dysfunction in Alzheimer's patients resulting in a reduction of the supply of energy to the brain. 04/25/2024 04:15 PM
Climate change could become the main driver of biodiversity decline by mid-century
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. Projections show climate change could become the main driver of biodiversity decline by the mid-21st century. 04/25/2024 04:15 PM
Vitamin D alters mouse gut bacteria to give better cancer immunity
Researchers have found that vitamin D encourages the growth of a type of gut bacteria in mice which improves immunity to cancer. 04/25/2024 04:15 PM
Food in sight? The liver is ready!
What happens in the body when we are hungry and see and smell food? A team of researchers 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 could open up new avenues for the treatment of type 2 diabetes. 04/25/2024 04:15 PM
Voluntary corporate emissions targets not enough to create real climate action
Companies' emissions reduction targets should not be the sole measure of corporate climate ambition, according to a new perspective paper. 04/25/2024 04:14 PM
Curiosity promotes biodiversity
Cichlid fishes exhibit differing degrees of curiosity. The cause for this lies in their genes, as reported by researchers. This trait influences the cichlids' ability to adapt to new habitats. 04/25/2024 04:14 PM
Airborne single-photon lidar system achieves high-resolution 3D imaging
Researchers have developed a compact and lightweight single-photon airborne lidar system that can acquire high-resolution 3D images with a low-power laser. This advance could make single-photon lidar practical for air and space applications such as environmental monitoring, 3D terrain mapping and object identification. 04/25/2024 01:16 PM
Treatment for deadly superbug C. diff may be weakening
The antibiotic vancomycin, recommended as first-line treatment for infection caused by the deadly superbug C. difficile (C. diff), may not be living up to its promise, according to new research. 04/25/2024 01:16 PM
Herring arrives earlier in the Wadden Sea due to climate change
Due to the changing climate, young herring arrive in the Wadden Sea earlier and earlier in spring. 04/25/2024 01:15 PM
With hybrid brains, these mice smell like a rat
Mice lacking an olfactory system have had their sense of smell restored with neurons from rats, the first time scientists have successfully integrated the sensory apparatus of one species into another. 04/25/2024 01:15 PM
Estimating emissions potential of decommissioned gas wells from shale samples
Extracting natural gas from shale formations can provide an abundant, lower-carbon footprint fossil fuel, but also creates concerns over increased methane emissions. Researchers have now developed a new tool that can estimate the emission potential of shale wells after they are no longer active. 04/25/2024 01:15 PM
Nanomaterial that mimics proteins could be basis for new neurodegenerative disease treatments
A newly developed nanomaterial that mimics the behavior of proteins could be an effective tool for treating Alzheimer's and other neurodegenerative diseases. The nanomaterial alters the interaction between two key proteins in brain cells -- with a potentially powerful therapeutic effect. 04/25/2024 01:15 PM
Scientists released long-term data of ground solar-induced fluorescence to improve understanding of canopy-level photosynthesis
A recent study utilized ground-based instruments to measure solar-induced fluorescence (SIF) that reflect plant health and photosynthesis. 04/25/2024 01:15 PM
The longer spilled oil lingers in freshwater, the more persistent compounds it produces
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. The longer that oil remains in freshwater, the more chemical changes it undergoes, creating products that can persist in the environment. 04/25/2024 01:15 PM
Warming Arctic reduces dust levels in parts of the planet
Dust can have a huge impact on local air quality, food security, energy supply and public health. Previous studies have found that dust levels are decreasing across India, particularly northern India, the Persian Gulf Coast and much of the Middle East, but the reason has remained unclear. Researchers found that the decrease in dust can be attributed to the Arctic warming much faster than the rest of the planet, a phenomenon known as Arctic amplification. This process destabilizes the jet stream and changes storm tracks and wind patterns over the major sources of dust in West and South Asia. 04/25/2024 01:15 PM
Identifying a new liver defender: The role of resident macrophages
Researchers discovered liver resident macrophages' pivotal role in defending against gut bacteria and related substances entering via the portal vein, particularly under compromised intestinal barrier conditions. Identified as 'sentinel macrophages,' they are activated by isoallo-lithocholic acid. This finding holds promise for developing preventive and therapeutic strategies for liver chronic inflammatory diseases, such as metabolic dysfunction-associated steatohepatitis (MASH), by enhancing the function of these macrophages to mitigate inflammation and improve treatment efficacy. 04/25/2024 01:15 PM
