A new study offers hope that kidney transplant patients could one day have a monthly treatment instead of multiple pills every day. The new treatment also may reduce side effects and increase the lifespan of the donor organ.  Currently, patients who have had a kidney transplant must take a cocktail of pills every day for the rest of their lives. These standard immunosuppressants prevent the immune system from attacking the new organ, but over time may damage kidney function and become less effective.  Standard immunosuppressants also are associated with diabetes, hypertension, high cholesterol, and cause side effects that lead most transplant ...

Florida’s Indian River Lagoon (IRL), one of the state’s most ecologically productive estuaries, is facing a growing but invisible threat that could reshape its marine ecosystems. Over the past decade, the lagoon has suffered severe degradation caused by nutrient pollution, excessive freshwater runoff, harmful algal blooms (HABs), and declining water quality. These changes have led to the loss of tens of thousands of acres of seagrass and have negatively impacted shellfish, fish, dolphins, manatees and other key species. A new study from Florida Atlantic University’s ...

As we shift toward more sustainable fuels, natural gas and biogas, which mainly contain methane (CH4), have become important sources of energy and raw materials for chemical production. However, these gases also contain impurities that must be removed before use. One major contaminant is carbon dioxide (CO2), which reduces the energy content of the gas and can cause corrosion in pipelines. One promising method for efficiently separating CO2 from these gases is filtration using graphene membranes containing ...

Thermoelectric conversion devices offer a promising route for sustainable heat-to-energy conversion. They are particularly attractive for recovering energy from waste heat, such as that produced by conventional fossil fuel-based engines, improving their overall energy efficiency. Around 20–50% of the input energy is lost as waste heat in industries. This could be used as source by thermoelectric conversion devices. These devices also have the potential to enable portable power generation, for example, to run small sensors in remote locations. Currently, most thermoelectric devices rely on the longitudinal thermoelectric effect in which electricity ...

International labor migration plays a vital role in supporting families across low- and middle-income countries, often providing a critical source of income for families back home. However, when mothers migrate abroad for work, young children may be left without steady parental care during important developmental stages. While this concern is widely discussed, there has been limited real-world evidence showing how policies that restrict maternal migration affect children’s outcomes.   A new study made available online ...
