The house fly might be a worldwide pest, but its genome will provide information that could improve our lives. From insights into pathogen immunity, to pest control and decomposing waste, the 691 Mb genome has been sequenced and analyzed by a global consortium of scientists, and is published in the open access journal Genome Biology. The genome highlights detoxification and immune system genes that are unique to the insect, and could be subjects of further study to help humans deal with toxic and disease causing environments.

A parasite spread by cat poop is causing a big problem for endangered sea otters in California, and researchers have finally figured out how. Sea otters were nearly wiped out by the fur trade at one point, but they've been slowly making a comeback thanks to conservation efforts and protection under the Endangered Species Act. While they're on the road to recovery the latest numbers from the U.S. Geological Survey released last month shows they're population growth has stalled, with the biggest issue being that they're dying in record numbers.

Large numbers of fish will disappear from the tropics by 2050, finds a new University of British Columbia study that examined the impact of climate change on fish stocks. The study identified ocean hotspots for local fish extinction but also found that changing temperatures will drive more fish into the Arctic and Antarctic waters.

Open pipes, widely used for a variety of purposes across the western U.S. landscape, have been reported as a "potentially very large" source of bird mortality according toresearch by scientists at Los Alamos National Laboratory (LANL). The finding was part of a peer-reviewed study accepted for publication by the "Western North American Naturalist" and authored by Charles D. Hathcock and Jeanne M. Fair.

Elephants are worth 76 times more when they’re alive than dead, according to a new analysis released this past weekend. The report follows on the heels of findings by WWF that the world has lost 50 percent of its wildlife over the past 40 years, with more than half of African elephants killed for ivory in just one decade. The analysis, conducted through the David Sheldrick Wildlife Trust's iworry campaign, compared the value of elephants to local economies to profits netted through the illegal ivory trade.

A vaccine for parasitic intestinal worms has been shown to be safe in Brazilian clinical trials, according to its US developer. Hookworm parasites infect more than 600 million people worldwide, attaching themselves to the intestines to feed on blood. Infection can lead to iron deficiency and capillary damage, and may retard children’s growth and mental development.

Hawai'i's sea turtles are afflicted with chronic and often lethal tumors caused by consuming non-native algae, "superweeds," along coastlines where nutrient pollution is unchecked. The disease that causes these tumors is considered the leading cause of death in endangered green sea turtles. The new research was just published in the scientific journal PeerJ. Turtles that graze on blooms of invasive seaweeds end up with a diet that is rich in a particular amino acid, arginine, which promotes the virus that creates the tumors. Scientists at the University of Hawai'i at Mānoa and their NOAA colleague estimate that adult turtles foraging at high-nutrient grazing sites increase their arginine intake 17–26 g daily, up to 14 times the background level.

The rusty-patched bumble bee (Bombus affinis), which has not been seen in the eastern United States in five years, has been found by a Smithsonian Conservation Biology Institute research team at Sky Meadows State Park in Delaplane, Va. This formerly common bee has disappeared from 87 percent of its range in the Upper Midwest and Eastern Seaboard and is feared headed for extinction. The research team, led by Bill McShea and Tom Akre of the Smithsonian Conservation Biology Institute and T'ai Roulston from the University of Virginia, surveyed bee populations at 17 Virginia sites from May through August to study the influence of land management on bee diversity. Only one individual of this now rare species was found among nearly 35,000 bees belonging to 126 species collected and examined by the study.

A mass of thousands of walruses were spotted hauled up on land in northwest Alaska during NOAA aerial surveys earlier this week. An estimated 35,000 occupied a single beach – a record number illustrating a trend in an unnatural behavior scientists say is due to global warming. Walruses (Odobenus rosmarus)—iconic arctic mammals that are only distantly related to seals—traditionally use sea ice to rest, breed, and give birth, and as a vantage from which to spot mollusks and other food sources. However, as their habitat warms and sea ice melts, walruses are forced to come to land more often and in greater numbers.

Americans love their dogs, but they don't always love to pick up after them. And that's a problem. Dog feces left on the ground wash into waterways, sometimes carrying bacteria — including antibiotic-resistant strains — that can make people sick. Now scientists have developed a new genetic test to figure out how much dogs are contributing to this health concern, according to a report in the ACS journal Environmental Science & Technology.
