While humans can survive large temperature fluctuations, such species as corals are only comfortable within a 12-degree temperature range. And rising global temperatures appear to be threatening their survival, according to Drew Harvell, Cornell professor of ecology and evolutionary biology.
A team of researchers from the UAB's Mutagenesis Group, led by Dr Jordi Surrallés, has identified one of the mechanisms used by cancer cells to resist chemotherapy.
It is a vision of information technology to store data in the smallest available units - single atoms - thus enabling the development of novel mass storage devices with huge capacities but compact dimensions. It is crucial to understand the mutual interaction and dynamics of individual spins, both for realising such a visionary device as well as to explore the limits of conventional mass storage media.
A new study from Joslin Diabetes Center may shed light on why some people can eat excessive amounts of food and not gain weight or develop type 2 diabetes, while others are more likely to develop obesity and this most common form of diabetes on any diet. The study, which used two strains of mice with differing tendencies to gain weight and develop diabetes on a high-fat diet, identified genetic and cellular mechanisms that may prevent certain mice on a calorie-dense diet from gaining weight and developing metabolic syndrome.
New research has examined the usefulness of bone marrow stem cells for treating male infertility, with promising results. The related report by Lue et al, “Fate of bone marrow stem cells transplanted into the testis: potential implication for men with testicular failure,” appears in the March issue of The American Journal of Pathology.
Researchers at the University of Illinois have found that a molecular pathway known to have a role in the progression of bone cancer in humans is also critical to the pathology of skeletal tumors in dogs and cats. Their work could lead to advances in the palliative care of companion animals afflicted with osteosarcoma.
There is no clear benefit from a hormone commonly prescribed to enhance the effectiveness of infertility treatments, according to a new review of studies.
The steroid hormones called glucocorticoids have potent effects on the body’s inflammatory and immune responses, so many fertility specialists prescribe them in hopes of making the lining of the uterus more receptive to embryo implantation. But lead review author Carolien Boomsma says that routine practice should stop.
Scientists at the University of Illinois have conducted a genetic analysis of vespid wasps that revises the vespid family tree and challenges long-held views about how the wasps’ social behaviors evolved.
In the study, published in the Feb. 21 Proceedings of the National Academy of Sciences, the researchers found genetic evidence that eusociality (the reproductive specialization seen in some insects and other animals) evolved independently in two groups of vespid wasps.
A penalty kick places a goalkeeper at such a disadvantage that only approximately 18% of penalty kicks are saved. However, some soccer fans think goalkeepers might save penalty kicks more easily by standing marginally to the left or right.
It turns out they're right! In an article published in the March issue of Psychological Science, Professors Rich Masters, John van der Kamp and Robin Jackson of the Institute of Human Performance at the University of Hong Kong found that penalty takers are more likely to direct the football to the side with more space.
Researchers have taken advantage of the unique coupled semiconducting and piezoelectric properties of zinc oxide nanowires to create a new class of electronic components and devices that could provide the foundation for a broad range of new applications.
