The COVID-19 pandemic significantly challenges cancer prevention and control in Africa, diverting resources away from cancer patients. However, this crisis also creates opportunities for innovation and improved access to cancer care.
The Asian tiger mosquito Aedes albopictus has been shown to transmit the Zika virus and trigger large outbreaks in a simulated environment. However, experimental studies suggest that the mosquito's infection rate is low, making it unlikely to cause major Zika virus epidemics.
Researchers from St Petersburg University have discovered a complex of rocks forming an ancient island arc in the Songkultau Mountains of Kyrgyzstan, dated to around 500 million years ago. The finding provides valuable insights into the geological history of Central Asia and has implications for understanding large ore deposits.
A novel virtual screening strategy identified pralatrexate as a promising treatment for Covid-19. Lab experiments showed that the chemotherapy medication inhibited viral replication more effectively than remdesivir.
Researchers have created microfabricated elastic diamonds that can stretch up to 10% without losing their shape. This controlled elasticity changes the diamond's electronic properties, including a reduced bandgap, making it suitable for advanced electronics and quantum information technologies.
Researchers from Iowa State University and Penn State University developed a method to measure and model desalination membranes, leading to improved water flow and salt removal. By creating uniform membrane density at the nanoscale, they found that membranes with fewer hot spots perform better.
High aerosol concentrations increase environmental humidity by producing more clouds, which can mix condensed water into the surrounding air. This humidification enhances updraft speeds, intensifying thunderstorms.
Researchers discover new mutations in malaria parasite that enhance resistance to sulfadoxine-pyrimethamine, a key preventive drug. These mutations are already widespread in Africa and Asia, threatening efforts to use the drug to prevent malaria in vulnerable groups.
Desalination membranes' density distribution at the nanoscale is crucial for performance. Thinner membranes with consistent density improve water filtration, contrary to previous thought that thickness matters more. This breakthrough could lead to 30-40% efficiency increase and cost savings.
Researchers identified traditional Ghanaian medicines that work in the lab against schistosomiasis, onchocerciasis, and lymphatic filariasis. Eight extracts showed good activity against these diseases, as well as trypanosomes, which cause other human diseases.
A large randomized clinical trial compared thresholds for blood transfusions in premature babies and found no advantage in survival or neurological impairment. The study, led by Dr. Rosemary Higgins of George Mason University, suggests that current guidelines for blood transfusions may not be optimal.
Preliminary data from the non-powered U.S. Phase 2 study showed that orally-administered opaganib was safe and demonstrated consistent trends of greater improvement in reducing oxygen requirement across key primary and secondary efficacy outcomes. The opaganib-treated arm demonstrated a greater improvement in reaching room air, reducti...
A new study by Ohio State University found that social media posts with matched imagery and text are more effective in recalling safety messages among young parents. Participants spent significantly longer on posts with matched messages, indicating better understanding and recall of safety knowledge.
Active matter systems, which can move under their own power, have been found to spontaneously order without higher-level instructions. Researchers developed a theory that predicts certain types of active matter will enter
Researchers found that combining CAR T cells with a proinflammatory environment created by STING pathway activation can improve their ability to attack tumor cells. This approach, combined with therapeutic antibodies, led to the complete eradication of breast tumors in mice.
A new study suggests that adding a small molecule to CAR-T cell therapy can boost the effectiveness of immunotherapy against breast cancer and other solid tumors. Researchers found that the addition of cGAMP activated an immune response, leading to enhanced T cell proliferation and tumor growth reduction.
Researchers have developed a new method to enhance the sensitivity of quantitative phase imaging, enabling the observation of tiny particles in living cells without labels or stains. The technique, called ADRIFT-QPI, produces images with seven times greater sensitivity than traditional methods.
Two recent studies from Oregon State University found that Oregon's Medicaid expansion led to increased prenatal care among low-income women and improved health outcomes for newborn babies. The expansion resulted in a nearly 2 percentage point increase in first trimester prenatal care utilization.
A new analysis suggests that subsidence, the sinking of ground's surface, will impact 19% of the world's population - 21% of GDP - by 2040. The model identifies areas with high susceptibility to subsidence, particularly in Asia, where 635 million inhabitants are exposed.
Researchers from the University of Texas at Austin and Penn State have developed a new understanding of desalination membranes, which can clean more water while using significantly less energy. The breakthrough could lead to increased access to clean water and lower water bills for individual homes and large users alike.
Researchers have successfully stretched diamond to achieve large, uniform tensile elastic straining, opening up new possibilities for advanced functional devices. The findings suggest the potential of strained diamonds as prime candidates for microelectronics, photonics, and quantum information technologies.
A study published in PLOS Pathogens reveals that mosquitoes feeding on blood multiple times increase malaria transmission potential, shortening the incubation period and making disease control more challenging. The research suggests that younger mosquitoes with reduced reproductive ability may contribute to infection, undermining curre...
