Researchers discovered strong evidence of a 55.5 million-year-old global warming event linked to a massive methane release. The 'latest Paleocene thermal maximum' led to the extinction or disappearance of deep-sea species and changed ecosystems. Further research is needed to understand this phenomenon.
The UofA research team is working to prevent rejection of transplanted islet cells, allowing diabetics to become insulin-free. Researchers are also developing procedures for transplanting islet cells before physical complications set in.
Victor Velculescu, a cancer researcher, develops SAGE technique to rapidly analyze gene expression in cells. The method provides a snapshot of all active genes and has potential applications in disease research.
The American Psychoanalytic Association's Fall 1999 meeting explores the latest in psychiatric research, including topics such as school violence and adolescent therapy. Key perspectives on psychoanalysis goals and interdisciplinary approaches to addressing complex issues were also presented.
Scientists at Johns Hopkins University have created a model that suggests a thin jet of relatively cold molten iron is streaming down across the liquid outer core from an area in the mid-Pacific to Earth's solid iron inner core. This 'cold front' could account for irregularities in the magnetic patterns observed over the Pacific.
Researchers at Brookhaven National Laboratory have discovered the molecular mechanism by which adenovirus binds to human cells, paving the way for the development of drugs that block infection. This breakthrough could lead to more effective vaccines and targeted therapies for viral infections.
A Yale research team has successfully turned supercritical carbon dioxide into a gel form, which could be used to extract oil from the ground instead of water. The new process is less expensive and more environmentally friendly than traditional methods.
Researchers at Princeton University have created ultrasmall plastic structures using a novel technique called LISA. The discovery has yielded insights into material behavior at nanoscales and has potential applications in computer memory chips, DNA sorting, and more. Refinements of the technique may lead to even smaller structures.
A new technique allows scientists to introduce desired genes directly into embryonic cells using the baculovirus, enabling the study of gene function in non-model organisms. This method has shown promising results in fruit flies, beetles, and other species, offering a breakthrough for understanding developmental processes.
A Mayo Clinic researcher found that nearly 8% of female soldiers on active duty in the US Army suffer from eating disorders. The study, led by Dr. Tamara Lauder, suggests that military fitness requirements and pressure to maintain a lean physique contribute to the higher prevalence of eating disorders among women.
Researchers have discovered a new target for treating chronic pain by disabling specific nerve cells that send pain signals to the brain. The study found that combining substance P with saporin can significantly reduce pain sensitivity, even when administered after neuropathic pain has developed.
