A strong relationship exists between Zimbabwe's peasant farmers and city-dwellers, with family ties playing a vital role in securing employment and housing. This connection is particularly evident during Christmas, when many return to their rural roots laden with city-purchased goods.
Researchers Eric Cornell, Carl Wieman, and Wolfgang Ketterle create a super-size boson by manipulating Bose-Einstein Condensates. They achieved this feat using optical and magnetic trapping techniques, demonstrating the wave nature of matter.
The collaboration will focus on understanding infectious disease pathogens, host interactions, and environmental factors. Researchers will develop technologies for rapid detection, identification, and remediation of pathogens.
Researchers from Utrecht have discovered that carbon nanofibres can effectively replace active carbon as a carrier for catalysts, enhancing the efficiency of hydrogenation reactions. The new material allows for the reuse of catalysts and has shown promise in the industrial-scale production of compounds like cinnamon alcohol.
Researchers found a wide swath of the western Amazon has a forest with minimal species change over distances of over 1000 kilometers. In contrast, forests on the Isthmus of Panama exhibit high beta-diversity due to abrupt variation in rainfall across the Central American isthmus.
A recent study found that liver transplant patients from African American and Asian backgrounds experience lower two-year and five-year survival rates compared to their white American and Hispanic counterparts. The study suggests a need for further research into the reasons behind these disparities in patient outcomes.
Research shows that ant diversity near forest fragments is higher in shade than sun coffee farms, and salamander abundance is higher in disturbed streams confluent with undisturbed ones. Conservation efforts may focus on making surrounding areas more conservation-friendly rather than connecting fragments.
Researchers have discovered an experiment conducted by George Sinclair, head gardener to the Duke of Bedford, in a garden at Woburn Abbey in South East England. The study investigated the relationship between biodiversity and ecosystem functioning, which is currently a hot topic in ecology. The findings push back the link between commu...
Research in tropical dry forests reveals that fragmentation decreases seedling quality, with reduced germination rates and smaller leaves. Despite the negative effects, isolated trees can still serve as genetic stepping stones for pollinating moths and gene flow between populations.
A Hopkins-led study found that African Americans and Asians have poorer graft rejection and survival rates after liver transplantation compared to white Americans and Hispanics. The study's lead author suggests that more research is needed to determine the causes of these disparities, with preliminary data suggesting socioeconomic fact...
A new report identifies knowledge gaps in Central American flora, particularly among fungi and mosses. The Mesoamerican and Caribbean Herbarium Network, which holds over one million plant specimens, is a key resource for future discovery.
UCSF scientists have demonstrated in animals how morphine's potent painkilling powers can be sustained without increasing dosages. By pairing morphine with an opioid that facilitates endocytosis, they showed that the natural cellular process can arrest the pattern of tolerance to morphine.
Researchers at Duke University Medical Center found that stem cell transplants performed within the first 28 days of life have a 95 percent success rate in treating newborn babies with severe combined immunodeficiency (SCID). The early transplants also stimulate a more robust and effective immune system, with reduced stresses on the th...
A team of paleoecologists from Amsterdam used pollen grains to accurately recreate the local climate in Southern Mexico and Northern Guatemala around 1000 AD. The study suggests that the collapse of the well-organised Maya empire led to widespread destruction of wildlife and agricultural areas, resulting in a drier climate.
Scientists have identified a key gene, Rad54, involved in neat DNA repair, preventing mutations and potentially improving cancer treatment. The study found that patients with an inactive Rad54 gene are more susceptible to radiotherapy side effects, leading to the idea of milder treatments.
A study of 63 young persons found that children who started wheezing between ages 2 to 5 were highly likely to continue wheezing in adulthood. Researchers also developed a brief questionnaire to predict future asthma-related healthcare utilization. Additionally, sleep disordered breathing was linked to obesity and craniofacial abnormal...
A new virtual reality-based rehabilitation system was developed by Rutgers researchers, providing intensive therapy and improving range of motion, finger speed, and strength for patients with chronic stroke hand impairment. The treatment showed significant improvements after just three weeks of use.
Researchers found that shipping-related imposex substances are not always transported to the seabed in stratified water. Instead, the harmful substance TBT, which causes imposex, is unable to sink through the boundaries between seawater layers.
The CECRE will create a comprehensive database on clinical research characteristics, including IRB review costs and funding sources. It will also develop a systematic framework for determining which projects require heightened scrutiny.
Scientists have successfully pinned down water at a hydrophobic surface, revealing capillary waves that ripple against the surface. This finding may aid in understanding structure of water films near patchy hydrophilic-hydrophobic surfaces.

The study also highlights the increasing role of injection drug use in spreading the disease, particularly among young men.
The study found a clear relationship between organic carbon and smectite clay minerals, suggesting that dissolved organic molecules are drawn into the crystal lattice where they are protected from oxidation. This process, known as adsorption, plays a crucial role in maintaining habitable conditions in the biosphere.
A NASA-funded study reveals that ancient South American forests hold the key to understanding US ecosystems before the industrial revolution. The study finds complex organic compounds as the main form of nitrogen in unpolluted ecosystems, contradicting previous beliefs about inorganic nitrogen.
