Not all galaxies have the luxury of possessing a simple moniker or quirky nickname. This impressive galaxy imaged by the NASA/ESA Hubble Space Telescope is one of the unlucky ones, and goes by a name that looks more like a password for a computer: 2XMM J143450.5+033843.

An influenza infection in birds gives a good protection against other subtypes of the virus, like a natural vaccination, according to a new study.

The benefits of a "Mediterranean diet" (MD) are well-known when it comes to colorectal protection, but it's hard to know specifically what elements of the diet are the healthiest.

Professionally active doctors increasingly hesitate to take on the task of tutoring students from undergraduate medical education. Stress and pressure from higher up, and sometimes also from colleagues, contributes to this ambivalence.

Based on a new molecular study of tissues biopsied from various parts of the upper digestive tract, researchers have identified significant, if subtle, differences in gene mutations and other factors that could help in developing more tailored treatment options for cancer patients.

A new study urges the UNESCO World Heritage Convention to better conserve wilderness areas within Natural World Heritage Sites. The study revealed that only 1.8 percent of the world's wilderness is protected in these sites.

Laws that require increasingly older kids to sit in car safety seats appear to have limited impact, new research has found.

Devoted runners suffer from a surprisingly high rate of injury. One reason for these injuries is that runners endure many shocks from the impact, and these cause vibrations that travel from the foot throughout the entire body. A researcher who focuses on acoustics and biomechanics, studied these repetitive shocks and investigated how runners adapt their running patterns.

The blue whale is the largest animal that has ever lived. And yet they feed almost exclusively on tiny crustaceans known as krill. The secret is in the baleen, a complex filter-feeding system that allows the enormous whales to strain huge volumes of saltwater, leaving only krill and other small organisms behind. Now, researchers who have described an extinct relative of baleen whales offer new insight into how baleen first evolved.

Researchers who have analyzed the Y chromosomes of more than 50 horses representing 21 breeds have found that the paternal lines of nearly all modern horses trace to stallions brought to Europe from the Orient over the last 700 years. The findings reveal the overwhelming influence of breeding schemes driven by strong selection on males.

Defective viruses incorporated into grass genomes may adapt to form partnerships with other genome-incorporated viruses in order to complete their life cycle, according to a new study. The findings suggest that partner viruses evolve in concert, enabling them to maintain their relationship over time.

Unmitigated climate change will make the United States poorer and more unequal, according to a new study. The poorest third of counties could sustain economic damages costing as much as 20 percent of their income if warming proceeds unabated.

Worker and queen honeybees exposed to field realistic levels of neonicotinoids die sooner, reducing the health of the entire colony, biologists have found. The researchers were also surprised to find that the neonicotinoid contaminated pollen collected by the honeybees came not from crops grown from neonicotinoid treated seeds, but plants growing in areas adjacent to those crops. This is season-long, field realistic research with typical exposure.

The world's open grasslands and the beneficial fires that sustain them have shrunk rapidly over the past two decades, due to a massive increase in agriculture, according to a new study.

Researchers have generated near-atomic resolution images of key steps in CRISPR-Cas3 function. The findings reveal multiple layers of error detection that prevent unintended genomic damage. Structural understanding informs efforts to improve the accuracy of CRISPR systems for gene editing and to reduce off-target effects.
