A new tool developed by University of British Columbia researchers could help ensure limited conservation dollars are well spent by determining which actions would save the most species per dollar.

In a case study published in Conservation Letters, researchers from UBC and Environment and Climate Change Canada (ECCC) applied the tool to endangered species in Canada for the first time, focusing on 15 species at risk in southwestern Saskatchewan.

Super Typhoon Mangkhut is a powerful tropical cyclone headed toward the northern Philippines. It is a Category 5 storm on the Saffir-Simpson hurricane wind scale. NASA-NOAA's Suomi NPP satellite provided a visible image as it passed over the Northwestern Pacific Ocean and stared the storm in its eye.

The British mainland was formed from the collision of not two, but three ancient continental land masses, according to new research.

Scientists have for centuries believed that England, Wales and Scotland were created by the merger of Avalonia and Laurentia more than 400 million years ago.

However, geologists based at the University of Plymouth now believe that a third land mass - Armorica - was also involved in the process.

BOSTON, MA (Sept. 13, 2018) -- Airborne marine biologists were amazed by the sheer abundance and diversity of large marine wildlife in their recent aerial survey of the Northeast Canyons and Seamounts Marine National Monument, the only marine national monument on the East Coast, about 150 southeast of Cape Cod. Scientists with the Anderson Cabot Center for Ocean Life at the New England Aquarium documented more than 600 animal sightings in just four hours, including a "superpod" of about 250 common dolphins and a rare sighting of a giant manta ray.

A new study in the journal Scientific Reports gets to the bottom of it: Why do dogs that are trained to locate poop sometimes find the wrong kind of poop?

It happens anywhere from 4 percent to 45 percent of the time, said Karen DeMatteo, a biologist in Arts & Sciences at Washington University in St. Louis. Her new research confirms that there are three viable, alternative explanations beyond errors in handler or dog training that can explain the collection of non-target scats with detection dogs in some ecosystems.

GAINESVILLE, Fla. --- Using the fossil record to accurately estimate the timing and pace of past mass extinctions is no easy task, and a new study highlights how fossil evidence can produce a misleading picture if not interpreted with care.

Human herpesvirus 6 (HHV-6) infects almost all of the human population, but only very few will show any symptoms during their lifetime: HHV-6 is one of the most widespread viruses among the population. Between 95 and 100 percent of healthy adults have antibodies to the virus which means that they have been infected at some point in the past.

The virus hides in the genomic DNA

University of Colorado Boulder researchers have discovered a key mechanism by which skin begins to develop in embryos, shedding light on the genetic roots of birth defects like cleft palate and paving the way for development of more functional skin grafts for burn victims.

"This study maps how skin development starts, from the earliest stages," said Rui Yi, senior author of the paper published online today in the journal Developmental Cell.

CORVALLIS, Ore. - An international collaboration led by Oregon State University scientists has made a key advance toward understanding which of the trillions of gut microbes may play important roles in how humans and other mammals evolve.

Researchers came up with a novel way of classifying the microbes - a taxonomy that groups them based on their ancestry and common distribution across mammals.

Findings were published this week in mBio.

AMHERST, Mass. - Based on field surveys in northern Afghanistan, Zalmai Moheb, an ecologist with the Wildlife Conservation Society's Afghanistan Program and a doctoral candidate in environmental conservation at the University of Massachusetts Amherst, with others, report this week that they have for the first time documented by direct observation the presence of two rare Asian wild goat species in the country.
