An ultra-high-resolution imaging technique using X-ray diffraction is a step closer to fulfilling its promise as a window on nanometer-scale structures in biological samples. Researchers report progress in applying an approach to “lensless” X-ray microscopy that they introduced one year ago, with the potential to yield insights for evolutionary biology and biotechnology. They have produced [...]

Researchers have developed a rapid, automated system to differentiate strains of influenza.
Over the past decade, researchers have developed a variety of reliable real-time and archival instruments to study sounds made or heard by marine mammals and fish. These new sensors are now being used in research, management and conservation projects around the world with some very important practical results. Among them is improved monitoring of endangered [...]

Pre-market approval by the FDA of cardiovascular devices is often based on studies that lack adequate strength or may have been prone to bias, according to a new study. Researchers found that of nearly 80 high-risk devices, the majority received approval based on data from a single study.
Scientists are developing new scaffolding technology which could be used to grow tissues such as skin, nerves and cartilage using 3D spaghetti-like structures.

The past year has been marked by a series of moral transgressions by powerful figures in political, business and celebrity circles. New research explores why powerful people — many of whom take a moral high ground — don’t practice what they preach.
Humans share at least 97 percent of their genes with chimpanzees, but, as a new study of transcription factors makes clear, what you have in your genome may be less important than how you use it.

Researchers have discovered how an oncogene gets activated in mature B cells, suggesting a new target for therapy in B cell lymphomas. The study marks the first time researchers have understood how the over-activation of c-myc can lead to blood-related cancers.
Scientists have identified the dominant odor naturally produced in humans and birds that attracts the blood-feeding Culex mosquitoes, which transmits West Nile virus and other life-threatening diseases. The groundbreaking research explains why mosquitoes shifted hosts from birds to humans and paves the way for key developments in mosquito and disease control.
