Now researchers have found a remarkable example: male spider mites guard and then actively strip off the skin of premature females that are soon to molt and mature to make them accessible for mating sooner.

Researchers have shown how bacteria can compete for food, but also cooperate thanks to differences in metabolism -- resulting in stably structured communities. Their models can accurately predict these interactions and can help to design microbiomes for specific applications in the future.

But not all the birds alive at the time made it. Why the ancestors of modern birds lived while so many of their relatives died has been a mystery that paleontologists have been trying to solve for decades. Two new studies point to one possible factor: the differences between how modern birds and their ancient cousins molt their feathers.

The research team found that 66% of hospitalized patients were colonized with bacteria resistant to third-generation cephalosporins, compared to 49% among community residents. Third-generation cephalosporins are typically used for serious infections, and resistance to these antibiotics leaves limited options for treating patients with some bacterial infections. The study was part of a pair of projects in Kenya and a third in Guatemala to determine the prevalence of antibiotic-resistant bacteria. The research also aimed to identify risk factors for colonization with bacteria resistant to important and frequently used classes of antibiotics, including third-generation cephalosporins.

One of the largest animals to live during the Cambrian, it was probably agile and fast, darting after soft prey in the open water rather than pursuing hard-shelled creatures on the ocean floor.

As a result, they're raising fewer young. By the end of the 21st century, climate change will cause springlike weather to begin 25 days earlier, but birds will only breed about seven days earlier. That change could lead to an average reduction of 12% in breeding productivity for songbird species.

Antonio Baeza, an associate professor in the Department of Biological Sciences, discovered the new worm while researching parental behaviors of the spiny lobster Panulirus argus in the Florida Keys. New research shows the worm affected embryo mortality, fecundity and reproductive output in brooding females.
