The European Molecular Biology Laboratory [EMBL] has developed a new computational tool that makes images obtained with cutting-edge microscopes even sharper. The technological advance and its applications are published in this week's online issue of the journal Nature Methods.

Psychologists have been fond of stating in recent years that human happiness, or what psychologists call subjective well-being, is largely independent of our life circumstances. The wealthy aren’t much happier than the middle class, married people aren’t much happier than single people, healthy people aren’t much happier than sick people, and so on.

Frog skin and human lungs hold secrets to developing new antibiotics, and a technique called solid-state NMR spectroscopy is a key to unlocking those secrets.

That's the view of University of Michigan researcher Ayyalusamy Ramamoorthy, who will discuss his group's progress toward that goal March 3 at the annual meeting of the Biophysical Society in Baltimore, Md.

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.
